Oilseeds Pretreatment Machine
Oilseeds Pretreatment Process
Cleaning , crushing, softening, flaking, cooking and pre-press. Oilseeds Pretreatment section is the important part of oil processing equipment, oilseeds pretreatment equipment will use different configuration and technology as different material¡¢different capacity and different finished oil level. Such as, rice bran pretreatment needs expanded section, palm fruit pretreatment need sterilizer section, Cottonseed pretreatment need delinting process etc.
The oilseeds pretreatment process is related to the oil seeds type:
Sunflower seeds: Cleaning, Shelling, Crushing/Flaking, Cooking
Soybeans: Cleaning, Crushing, Softening, Flaking (Expansion)
Peanuts: Cleaning (Shelling), Crushing/Flaking, Cooking
Rice bran: Cleaning (Rice bran and tip separation), Softening, Expansion
Cottonseed: Cleaning, Shelling, Flaking, Expansion
Rapeseed: Cleaning, Softening, Flaking, Cooking
Flow Chart of Oilseeds Pretreatment Pre-press
Oilseeds pretreatment equipment of HUATAI Oil machinery advantages:
1.To reduce the wear on the follow-up device, improve the quality of workshop environment.
2.Improving equipment production, enhance the oil yield rate, maximum ensure quality of oil, cake and by-products.
3.Minimum oilseeds broken rate, the destructive effect for cake protein can down to the lowest.
Technical Specifications
Engineered for efficiency, built for performance.
Working Principle
Cleaning & destoning
Vibrating screen, magnet and destoner remove impurities, stones and metal to >99% purity.
Crushing
Roller crusher breaks seeds to uniform size for even flaking.
Softening
Conditioning cylinder warms and softens kernels to the right plasticity.
Flaking
Flaking rolls form thin, uniform flakes to shorten the oil pathway.
Cooking / conditioning
Stacked cooker adjusts moisture and temperature to the optimal pre-extraction state.
Extruding / pre-pressing
Extruder gelatinizes flakes (for extraction) or pre-press recovers part of the oil from high-oil seeds.
Why Choose This Equipment
