Oil Seed Preparation
The preparation section is the first and most critical stage in edible oil solvent extraction plants. The efficiency of the entire extraction process depends largely on how well the oil seeds are prepared. This stage involves cleaning, conditioning, cracking, flaking, Dehuller, Hull Separator and cooking the seeds to achieve optimum cell rupture, maximize oil yield, and ensure smooth downstream processing.
Seed Cleaners
Seed cleaning is the first and one of the most vital steps in the oilseed preparation process. The purpose of seed cleaning is to remove all foreign materials and impurities from the raw seeds before they enter further processing stages. Clean seeds not only improve the efficiency of the solvent extraction process but also protect downstream equipment from damage and ensure the production of high-quality edible oil and meal
Key Features & Benefits:
- Improved oil yield and product quality
- Protection of downstream machines such as crackers, de-stoners, and flakers
- Reduced solvent loss during extraction
- Consistency in seed preparation leading to stable plant operation
De-stoner
The de-stoner is designed to remove high-density foreign materials such as stones, glass, and metal pieces from oilseeds. Since stones and heavy impurities have similar size to the seeds, simple screening cannot separate them effectively. The de-stoner works on the principle of density difference, using a combination of vibration and air flow.
Key Features & Benefits:
- Efficient separation of heavy impurities that could damage downstream equipment
- Adjustable air flow and deck inclination for different seed types
- Protects crackers, flakers, and extruders from severe wear
- Ensures consistent product purity and improves oil quality
Cracker
Crackers reduce oilseeds into smaller pieces to facilitate efficient oil cell rupture during flaking. Uniform cracking increases seed surface area and enables better heat transfer and conditioning.
Key Features & Benefits:
- Precision-designed chilled cast rollers for uniform cracking
- Roller gap adjustmentfor different oilseeds (soybean, sunflower, cottonseed, etc.)
- Heavy-duty bearings and drive system for continuous operation
- Ensures higher flaking efficiency and better oil recovery
Dehuller
Dehullers are used to separate seed kernels from their outer husks or hulls. Removing hulls enhances oil quality, reduces fiber content in meal, and increases efficiency in further processing. In addition, A hull separator is used to ensure effective separation of kernels from hulls, helping to prevent excess fiber in the final meal and ensuring maximum oil recovery.
Key Features & Benefits:
- High-speed impact or abrasion principle for effective hull removal
- Adjustable design for different oilseeds like soybean, sunflower, groundnut, and cottonseed
- Reduced fiber carry-over, improving meal digestibility and protein content
- Lower wear and tear on downstream equipment
Cooker
Engineered for Maximum Oil Recovery & Efficient Extraction. The Sungates Cooker is designed to optimize seed structure before pressing or solvent extraction. It ensures uniform heating, moisture control, enzyme deactivation, and cell structure modification, resulting in higher oil yield and improved DOC quality.
Key Features & Benefits:
- Thermal Conditioning Softens seed matrix for better oil release
- Moisture OptimizationLive steam integration maintains ideal moisture levels (8–12%)
- Enzyme Deactivation Essential for soybean and rice bran to control FFA formation
- Protein Structure Refinement Enhances DOC digestibility and pellet quality
Flaker
The flaker converts cracked seeds into thin flakes, exposing maximum surface area for oil extraction. This step is crucial in preparing oilseeds for solvent penetration
Key Features & Benefits:
- Large diameter rolls with rigid support to maintain flake thickness
- Hydraulic or spring-loaded system for roll pressure adjustment
- Flakes produced with uniform thickness, improving solvent extraction rate
- Robust design ensuring long life and minimal maintenance
Conditioner
The conditioner adjusts seed moisture and temperature before flaking or expanding. Proper conditioning improves flake pliability, reduces fines, and increases oil recovery
Key Features & Benefits:
- Direct or indirect steam injection for uniform heating
- Stainless steel chamber with agitators for homogeneous mixing
- Precise control of moisture and temperature
- Ensures optimum preparation for solvent extraction
Expander
The expander subjects oilseeds or flakes to high temperature, pressure, and mechanical shear. This ruptures cellular structures, gelatinizes starches, and reduces anti-nutritional factors. Expanded material forms porous collets, improving percolation of solvent and reducing fines
Key Features & Benefits:
- Steam injection for precise cooking and conditioning
- Produces uniform collets with high porosity
- Increases extraction efficiency and reduces solvent loss
- Improves meal quality for animal feed
Cooler
After expansion, oilseed collets must be cooled to ambient temperature to prevent condensation, clumping, or microbial growth. The cooler ensures product stability before entering the extraction section
Key Features & Benefits:
- Counter-flow cooling technology for efficient heat exchange
- Gentle product handling to prevent breakage of collets
- Even cooling to maintain product moisture balance
- Ensures safe storage and smooth extraction performance
