Raj Process Equipments & Systems Pvt. Ltd. is a pioneer in compressed biogas (CBG) technology, offering patented solutions for biogas generation and purification. As one of India’s leading CBG plant manufacturers, we deliver turnkey systems that convert organic waste into high purity compressed biogas — a sustainable, eco friendly fuel for the future. Aligned with national initiatives like SATAT and GOBARdhan, Raj Process is driving India’s clean energy transition by designing and executing next generation CBG plants across the country and globally. Organic Waste In. Clean Fuel and Fertilizer Out. Compressed Biogas — commonly called Bio-CNG — is biomethane produced from the anaerobic digestion of organic waste, purified to 96–99% methane purity, and compressed to 200–250 bar for dispensing and sale. It is chemically identical to fossil CNG in energy value, calorific content, and physical properties. Every CNG vehicle on the road can run on CBG without any modification. Every existing CNG dispensing station is compatible. The process, in simple terms: Organic waste enters a sealed, temperature-controlled digester. Over 15–25 days, a carefully managed consortium of microorganisms breaks it down and produces raw biogas — typically 55–65% methane and 35–40% CO₂. This raw biogas passes through our cleaning and upgrading systems, where CO₂, hydrogen sulphide, moisture, and trace contaminants are removed. What remains is biomethane meeting IS 16087:2023 specifications. We compress it, store it in high-pressure cascade systems, and it is ready for sale to Oil Marketing Companies or direct consumers. The digestate — the solid and liquid material remaining after digestion — is not waste. It is a nutrient-rich Fermented Organic Manure (FOM) and bio-slurry that sells as a premium organic fertilizer, adding a second revenue stream to your plant from day one. One plant. One waste problem solved. Two revenue streams generated. That is the CBG business model. FEEDSTOCKS The feedstock landscape for CBG production in India is broad. We have designed and commissioned plants running on: Napier grass and dedicated energy crops Press mud from sugar mills Cattle and cow dung Distillery spent wash — molasses based and grain-based Municipal solid waste (organic fraction) Poultry litter Food processing effluents Fruit and vegetable market waste Rice straw and wheat straw Sugarcane trash and bagasse Sewage sludge Biogas yields across these feedstocks range from 30 m³ per tonne for cattle dung to 350–400 m³ per tonne for high-fat food waste. The differences are not just in yield — each feedstock brings its own pre-treatment requirements, C:N ratio considerations, sulphur loading, and digester design implications.

Premium Spray Drying Solutions: Engineering Excellence by Raj Process In the landscape of industrial thermal processing, Raj Process has solidified its reputation as the premier spray dryer manufacturer in India. Our systems represent the pinnacle of liquid-to-powder conversion technology, offering unparalleled efficiency for diverse industrial sectors. The Science of Spray Drying: How It Works Spray drying is a sophisticated method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. It is the preferred method for thermally sensitive materials because the drying process is near-instantaneous. The process follows four fundamental stages: Atomization: The liquid feed is turned into tiny droplets using a nozzle or rotary atomizer. Spray-Air Contact: The droplets meet a stream of hot air. Drying: Moisture evaporates instantly, cooling the particle as it dries. Separation: The dry powder is recovered from the exhaust air using cyclones or bag filters.

High-Efficiency Rotary Dryer Solutions: The Ultimate Industrial Guide In the modern industrial landscape, moisture control is the difference between a high-quality product and a wasted batch. As a premier Rotary Dryer Manufacturer, RAJ Process provides engineering marvels designed to handle the most challenging materials with precision, durability, and thermal efficiency. Our rotary drying systems are engineered to transform wet cakes, powders, and minerals into high-value dry products. Whether you are processing silica sand or delicate coconut powder, our technology ensures uniform drying with minimal energy consumption. 1. What is a Rotary Dryer? (Technical Overview) A Rotary Dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct or indirect contact with a heated gas. The dryer consists of a large, rotating cylindrical tube, usually supported by steel beams. The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. How It Works: The Three-Step Process Feeding & Distribution: Wet material is fed into the drum. Internal “flights“ (lifting blades) pick up the material and shower it through the hot air stream. Heat Transfer: As the drum rotates, the material makes contact with heated gas. This can be done via Direct Firing (gas touches material) or Indirect Firing (heat transferred through the drum wall). Moisture Evacuation: Vaporized moisture is carried away by the air stream and filtered through a cyclone or bag filter, while the dry product exits the lower end. 2. Industry-Leading Capacity & Performance We design our systems to accommodate everything from boutique processing to massive mining operations. 3. Rotary Dryers vs. Calciners: Versatility Redefined One of the key advantages of our engineering is the ability to use these units as Calciners. Drying: Removes surface or bound moisture at lower temperatures. Calcination: Involves heating the material to high temperatures (up to 600°C) to induce a chemical change or phase transition. Because our drums are built with heat-resistant alloys, a RAJ Process Rotary Dryer can double as a calciner, making it a “two-in-one“ asset for chemical and mineral plants. 4. Strategic Advantages of Our Rotary Drying Systems A. Material Versatility Unlike flash dryers or spray dryers, rotary dryers are incredibly “forgiving.“ They can handle: Sticky Cakes: Using specialized internal chain systems to prevent clogging. Non-Uniform Sizes: From fine dust to large mineral chunks. Abrasive Solids: Reinforced shells that withstand constant friction. B. Energy Efficiency & Heat Recovery We integrate advanced heat exchangers that pre-heat the incoming air using the exhaust gas, significantly lowering the “Cost Per Ton“ of dried product. C. Customized Internal Flights The “flights“ inside the drum are the secret to efficiency. We customize flight patterns (radial, cruciform, or honeycomb) based on your material’s flow characteristics to ensure a perfect “curtain“ of material for maximum heat exposure. 5. Extensive Industrial Applications Our rotary dryers are deployed across diverse sectors. Here is how we add value to specific materials: Mineral & Construction Industry Silica Sand: Essential for glass and foundry industries. We provide high-temp drying to ensure 0.1% moisture content. Limestone & Gypsum: High-capacity drying for cement and wallboard production. China Clay: Precise temperature control to prevent discoloration. Agriculture & Food Processing Coconut Powder: Gentle drying at controlled temperatures to preserve natural oils and flavor. Bagasse: Converting sugar mill waste into high-calorie biofuel by reducing moisture for better combustion. Grain & Seed: Large-scale moisture reduction for long-term storage. Chemical & Waste Management Sludge Drying: Reducing the volume of industrial sludge for cost-effective disposal. Fertilizers: Creating free-flowing granules that don't cake during packaging. 6. Engineering & Maintenance: Built for Longevity As a leading manufacturer, we don't just sell equipment; we provide a lifecycle solution. Precision Alignment: Our technicians use laser alignment for the trunnion rollers to ensure the drum rotates with minimal vibration, extending the life of the bearings. Sealing Technology: Advanced graphite or mechanical seals prevent dust leakage and maintain thermal vacuum. Automation: Fully integrated PLC panels allow for remote monitoring of moisture levels and fuel consumption.

In the modern era of “Zero Liquid Discharge“ (ZLD) and high-purity chemical processing, the demand for efficient thermal separation has never been higher. As a premier Agitated Thin Film Dryer (ATFD) Manufacturer, RAJ Process delivers cutting-edge evaporation solutions engineered to handle the most complex, heat-sensitive, and high-viscosity fluids. Our systems are designed to maximize heat transfer, minimize residence time, and ensure that even the most difficult-to-handle slurries are converted into high-quality solids or concentrated liquids. 1. Understanding ATFD Technology: The Science of Thin Films An Agitated Thin Film Dryer (ATFD) is a vertical or horizontal thermal separation unit. Unlike traditional evaporators where the liquid sits in a vessel or flows through tubes, the ATFD uses mechanical agitation to create a highly turbulent, thin film of product against a heated jacketed wall. How the Process Works Feed Entry: The liquid or slurry enters the top of the cylindrical heating jacket. Thin Film Formation: A high-speed rotor with specialized blades spreads the liquid into a thin film (typically 0.5 to 2 mm thick) across the internal heated surface. Rapid Evaporation: Because the film is so thin, the heat transfer is near-instantaneous. Vapors travel upward through a mist eliminator. Solid Recovery: As the moisture evaporates, the material transitions from a liquid to a paste, and finally into a dry powder or flakes, which are discharged at the bottom. 2. Technical Specifications & Performance Chart Our ATFD units are custom-built to match the thermal sensitivity of your specific product. Below is the standard technical roadmap for our high-performance systems. 3. Specialized Rotor Blade Configurations The “heart“ of an ATFD is its rotor. Depending on whether your material is sticky, abrasive, or heat-sensitive, we offer four distinct blade configurations to optimize your yield: A. Fixed Blade Rotor Best For: Low to medium viscosity liquids. Mechanism: Maintains a precise, fixed clearance between the blade tip and the heated wall. It is ideal for continuous, high-speed evaporation of stable solutions. B. Cylindrical Wiper Rotor Best For: Highly viscous fluids and concentration tasks. Mechanism: Uses wipers to physically “wipe“ the film across the surface, preventing any stagnant “hot spots“ that could degrade the product. C. Spring-Loaded Rotor Best For: Products that tend to scale or form a hard crust on the walls. Mechanism: The blades are pushed against the wall by spring tension, ensuring the heating surface stays clean and heat transfer remains at 100% efficiency throughout the run. D. Centrifugal Blade Rotor Best For: Slurries with high solids content. Mechanism: Utilizes centrifugal force to press the blades outward. As the product thickens, the blades adapt to the changing resistance, making it the most versatile option for multi-product plants. 4. Key Advantages of Using ATFD Systems Zero Liquid Discharge (ZLD) Compliance In today’s regulatory environment, industrial plants are under pressure to eliminate wastewater. Our ATFDs act as the final stage of a ZLD plant, taking the “reject“ from Reverse Osmosis (RO) or Multi-Effect Evaporators (MEE) and turning it into dry, disposable salt or reusable solids. Minimal Residence Time Traditional evaporators can subject a product to heat for hours. In an ATFD, the residence time is measured in seconds. This is critical for pharmaceuticals, flavors, and enzymes that would otherwise lose their potency or change color if exposed to heat for too long. Single-Pass Operation Our technology allows for a “liquid-in, powder-out“ transition in a single pass. This eliminates the need for separate thickeners, centrifuges, or secondary dryers, significantly reducing your plant's footprint and capital expenditure. 5. Industrial Applications Across Sectors Pharmaceutical & Biotech Concentrating APIs: Gentle handling of active pharmaceutical ingredients. Solvent Recovery: Efficiently separating high-value solvents from waste streams. Herbal Extracts: Maintaining the bio-activity of natural extracts during concentration. Chemical & Petrochemical Dye & Pigment Concentration: Achieving high-purity colorants. Agrochemicals: Drying pesticides and fertilizers into stable powder forms. Resin Processing: Handling high-viscosity polymers without clogging. Food & Beverage Dairy Products: Concentrating whey and milk derivatives. Fruit Pulps: Reducing volume for transport while preserving nutritional integrity. Sweeteners: Processing sugar alcohols and corn syrup. 6. Engineering Excellence: Why RAJ Process?

With global energy shifts and India’s ambitious E20 (20% Ethanol Blending) mandate, the demand for efficient, multi-feedstock distilleries has reached an all-time high. Raj Process Equipments & Systems Pvt. Ltd. is at the forefront of this revolution, providing bankable, first-principles engineered solutions that turn raw agricultural waste into high-value ethanol and clean energy. Whether you are operating a molasses-based unit, a grain-based distillery, or a multi-feedstock plant, the goal remains the same: Maximizing yield while achieving Zero Liquid Discharge (ZLD). RajFerment – Advanced Fermentation Systems The Science of Superior Alcohol Conversion At the heart of every distillery lies the fermentation house. Raj Process has engineered a next-generation system that focuses on yeast health and substrate utilization. Our fermentation architecture is designed to handle rapid changeovers between molasses, cane syrup, and grain feedstocks without losing productivity. Technical Features & Innovations Advanced Agitator Design: We utilize custom-engineered, low-shear agitators. High-shear mixing often ruptures yeast cells; our design ensures uniform nutrient distribution while preserving yeast viability, leading to higher alcohol percentages in the wash. High-Conversion Architecture: Precision tank geometry and internal cooling coils (or external PHEs) maintain the ideal temperature (32–34°C). This prevents “stuck fermentation“ during peak summer months in regions like Maharashtra and Uttar Pradesh. Liquefaction Integration: For grain-based distilleries, our fermentation house integrates seamlessly with the liquefaction section, ensuring that 100% of starch is converted into fermentable sugars. Integrated CO₂ Capture: Instead of venting emissions, our systems capture and purify CO₂, transforming it into food-grade revenue. RajPurify – High-Purity Distillation Platforms Primary Goal: Efficiency in Every Drop Distillation is the most energy-intensive part of a distillery. RajPurify systems are engineered to minimize steam consumption through Multi-Pressure Distillation and advanced heat integration.

(ABEPL) project, where we delivered the ethanol separation package for the world's first bamboo-based 2G refinery. The Raj Process 2G Technology Cycle Step 1: Biomass Pretreatment (The Lignin Barrier) Lignocellulosic biomass is naturally resistant to breakdown. Our pretreatment systems use a combination of Mechanical Shredding and Steam Explosion (or chemical impregnation) to disrupt the lignin-hemicellulose matrix. Why Raj Process? Our patented Non-Clog Extra Long Tube systems ensure that even the most “sticky“ or fibrous residues don't cause downtime. Step 2: Enzymatic Hydrolysis (Saccharification) Once pretreated, the biomass is treated with specialized cellulase and hemicellulase enzymes. This stage converts complex cellulose into simple C6 (Glucose) and C5 (Xylose) sugars. KPI: We achieve up to 85% conversion efficiency, maximizing the sugar recovery from every ton of straw or bamboo. Step 3: Advanced Co-Fermentation Standard yeast cannot ferment C5 sugars efficiently. Raj Process employs Next-Generation Co-Fermentation technology. We use engineered microbial strains that ferment both C5 and C6 sugars simultaneously, significantly increasing the total alcohol yield per ton of feedstock. Step 4: RajPurify Distillation & Dehydration Our multi-pressure vacuum distillation columns separate alcohol from the wash with extreme precision. Purity: We reach 99.5% to 99.7% purity (Fuel-Grade) using Molecular Sieve Dehydration (MSDH) technology, ensuring compatibility with the latest BS-VI and Flex-Fuel vehicle engines.

The spentwash Challenge in Modern Distilleries In the wake of India’s E20 Ethanol Blending Mandate and the global push for sustainability, the ethanol industry is booming. However, this growth brings a massive environmental hurdle: Spentwash. Also known as vinasse or distillery slop, spentwash is the dark, viscous, and highly acidic liquid left after the distillation of molasses or grain. With a high BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand), untreated spent wash can devastate local ecosystems. Raj Process Equipments provides the definitive solution with our Next-Generation Spent wash Dryers, designed to achieve 100% Zero Liquid Discharge (ZLD) while creating a revenue-generating by-product. Why Traditional Waste Management is Failing For decades, distilleries relied on “Lagooning“ or dilution. These methods are no longer viable in 2026 due to: Strict Regulatory Norms: CPCB and SPCB have mandated absolute ZLD for all distilleries. Groundwater Contamination: Leaching of salts and organic matter into the water table. High Land Footprint: Massive lagoons occupy valuable industrial land. Odor and Public Health: Foul smells lead to community friction and legal liabilities. The Raj Process Spentwash Dryer eliminates these issues by reducing waste volume by over 80%, converting a problematic liquid into a dry, easy-to-handle powder. The Raj Process Spentwash Drying Mechanism Our system is not a simple heater; it is a sophisticated thermal engineering platform. 1. Advanced Evaporation & Concentration Before drying, the spentwash is concentrated in our Multi-Effect Evaporators (MEE) or Mechanical Vapor Recompression (MVR) systems. This reduces the moisture content to a level where thermal drying becomes highly energy-efficient. 2. Thermal Drying & Solidification The concentrated wash is fed into the Raj Process Dryer. Utilizing controlled hot air or steam, we flash-dry the material. The result is a fine, free-flowing powder that retains all the nutrient value of the original waste but without the water weight. 3. Patented Energy Recovery Energy is the highest cost in drying. Raj Process systems are engineered with Waste Heat Recovery (WHR) units. We recycle the latent heat from the exhaust vapors to pre-heat the incoming spentwash, cutting fuel costs by up to 25%. 4. Emission & Odor Control (The Scrubber System) To address the “foul odor“ problem, our dryers are equipped with integrated venturi scrubbers and activated carbon filters. This ensures that the air released into the atmosphere is clean, odorless, and compliant with air quality standards. The Economic Value – Waste into Resource 1. Production of Bio-Potash Fertilizer The dried powder from a Raj Process dryer is a “Gold Mine.“ India currently imports a vast majority of its Potash. By drying spentwash, distilleries produce Bio-Potash, which can be sold to farmers or fertilizer companies at lucrative rates (₹15,000 to ₹25,000 per tonne). 2. Fuel Substitution In certain plant configurations, the dried solids have a Calorific Value of approximately 2,200 to 2,500 kcal/kg. This allows the powder to be co-fired in the distillery's boiler, reducing the consumption of expensive coal or bagasse. 3. Drastic Logistics Savings By reducing the volume of waste by over 80%, the cost of transporting waste for composting or disposal is virtually eliminated. 100 truckloads of liquid waste are reduced to just 20 truckloads of high-value powder. Chapter 5: Why Choose RAJ Process Equipments? 1. Proven Large-Scale Track Record: We have successfully commissioned some of the largest spentwash drying units in Asia and South America. Our systems are not theoretical; they are field-proven assets. 2. Turnkey EPC Capability: We provide everything from the initial chemical analysis of your spentwash to the final packaging unit for the dried powder. 3. Compliance Assurance: Our systems are designed to help you meet the most stringent Zero Liquid Discharge (ZLD) norms, ensuring your distillery stays operational even under strict environmental audits. 4. Advanced Automation: With real-time monitoring of moisture levels and flow rates, the Raj Process system adjusts itself to variations in spent wash quality, ensuring a consistent final product.

As the global community accelerates toward the Net-Zero 2050 goal, industrial emissions are under unprecedented scrutiny. In India, the Carbon Credit Trading Scheme (CCTS) and stricter CPCB norms have turned carbon management from a corporate social responsibility (CSR) activity into a core economic necessity. Raj Process Equipments & Systems Pvt. Ltd. is the leading engineering partner in this transition. We provide turnkey Carbon Capture and Utilization (CCU) solutions that do more than just “store“ carbon; we empower industries to recycle $CO_2$ into high-value products like Green Methanol, Sustainable Aviation Fuel (SAF), and Food-Grade Dry Ice. With five advanced manufacturing facilities and a legacy of process engineering, Raj Process is redefining the circular economy. Understanding CCU – From Waste to Value What is CCU?Carbon Capture and Utilization (CCU) is the process of capturing Carbon Dioxide ($CO_2$) directly from industrial flue gases—such as those from distilleries, power plants, and refineries—and converting it into useful products. CCU vs. CCS: The Profitable Alternative Unlike Carbon Capture and Storage (CCS), which involves pumping $CO_2$ underground at a significant cost, CCU focuses on valorization. By treating $CO_2$ as a feedstock rather than a waste product, industries can create new revenue streams that often offset the entire cost of the capture plant. The Raj Process CCU Technology Suite At Raj Process, we understand that no two flue gas streams are the same. We offer a diverse range of capture technologies tailored to specific industrial profiles. 1. Advanced Chemical Absorption (Solvent-Based)This is the gold standard for high-volume emissions. We utilize specialized amine-based or potassium carbonate-based solvents to selectively “scrub“ $CO_2$ from flue gases.Efficiency: Achieves 95% to 99% recovery.Application: Ideal for large-scale ethanol plants and thermal power units. 2. Membrane SeparationFor plants with space constraints or lower flue gas volumes, our membrane systems offer a compact, energy-efficient solution. This technology uses semi-permeable materials to separate $CO_2$ based on molecular size and solubility. 3. Adsorption & VPSA SystemsUsing solid adsorbents like Zeolites or Activated Carbon, our Vacuum Pressure Swing Adsorption (VPSA) systems trap $CO_2$ molecules. This is a dry process, ideal for applications where water usage must be minimized. 4. Cryogenic Purification & Lique faction Once captured, the $CO_2$ must be purified. Raj Process systems deliver 99.9% purity, meeting the stringent requirements for:ISBT (International Society of Beverage Technologists) standards for carbonated drinks. Pharmacopoeia standards for medical use. Why Partner with Raj Process? 1.

Raj Process designs utilize Heat Integration Schemes, using waste heat from your existing boiler or evaporator to drive the $CO_2$ stripper, drastically reducing OPEX. 4. Global Compliance:Our plants are designed to help you generate Carbon Credits (Verified Emission Reductions) that can be traded on international markets like the Gold Standard or Verra.

In the industrial landscape of 2026, waste is no longer a liability—it is a raw material. As global agriculture shifts toward organic and sustainable inputs, the demand for uniform, nutrient-rich granules has skyrocketed. However, many industries, particularly distilleries and sugar mills, face the challenge of handling fine, dusty by-products like Spentwash Powder and Press-mud. Raj Process Equipments & Systems Pvt. Ltd. provides the definitive solution with our Advanced Industrial Granulation Plants. We specialize in “Value Engineering,“ taking low-value powders and transforming them into free-flowing, easy-to-handle, and highly marketable granules. With five state-of-the-art manufacturing facilities and a legacy of process innovation, Raj Process is helping industries achieve Zero Waste while creating new revenue streams in the bio-fertilizer sector. What is Industrial Granulation? Granulation is the process of particle enlargement, where small particles or powders are gathered into larger, permanent aggregates. For industrial by-products, this is essential for: Improved Flowability: Fine powders often clog machinery and are difficult to transport. Granules flow easily through industrial dispensers and agricultural seed drills. Controlled Release: In fertilizers, granules ensure that nutrients are released slowly into the soil, preventing “nutrient leaching.“ Dust Reduction: Eliminating fine dust reduces respiratory hazards for workers and prevents material loss due to wind during field application. The Raj Process Technical Advantage At Raj Process, we don't believe in “one-size-fits-all.“ Our granulation plants are engineered based on the specific chemical and physical properties of your feedstock. 1. High-Precision Pan & Drum Granulators Depending on the required throughput, we offer high-efficiency Disc (Pan) Granulators for precision size control and Rotary Drum Granulators for massive industrial volumes. Custom Scrapers: Our systems feature adjustable scrapers to prevent material buildup, ensuring a smooth, continuous process. 2. Advanced Moisture & Binder Management The “secret“ to perfect granules lies in the binder-to-powder ratio. Our automated dosing systems precisely inject water or organic binders (such as molasses) to create strong, spherical granules that don't crumble during transport. 3. Integrated Energy-Efficient Drying Freshly formed “green“ granules contain moisture that must be removed. We integrate Fluid Bed Dryers (FBD) or Rotary Dryers that utilize waste heat from your existing boilers, drastically reducing operational costs (OPEX). Major Applications – Turning Waste into Gold 1. Press-Mud Granulation (Sugar Industry) Press-mud is a bulky, smelly waste. Raj Process transforms this into Bio-Fertilizer Granules rich in organic carbon. These granules are a direct substitute for chemical fertilizers, commanding high market prices. 2. Spentwash / Potash Powder Granulation (Distilleries) For distilleries using our Spentwash Dryers, the resulting potash powder is often too fine for direct use. Our granulation plants turn this powder into Potash-Rich Pellets, which are essential for increasing crop yields in fruit and vegetable farming. 3.
