Pretreatment is a series of processing steps before oil extraction, which is called oilseeds pretreatment. The basic process includes: cleaning, shelling/peeling, crushing/softening/flaking, cooking/expansion, etc. Its purpose is to remove various impurities in the oil seeds and adjust the moisture and temperature of the oil seeds to facilitate the oil pre-press and oil solvent extraction plant. Depending on the type of oil seeds, the oilseeds pretreatment processes and methods selected are also different.
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
The related equipment in Oilseeds Pretreatment Plant:
Cleaning equipment: Cleaning screen, specific-gravity stoner, magnetic separator
Shelling/Peeling: 1. Shelling machine (disc/roller/centrifugal) for sunflower seeds/cotton seeds
2. Peeling for soybean: conditioning/drying/aspiration/screening series equipment
Crushing/Softening/Flaking: Crusher, softening pot/tower, flaking machine
Cooking/Expansion: Cooker, extruder
The design of the oilseed pretreatment process fully considers energy saving and environmental protection: controlling dust emissions, recovering heat energy, reducing production energy consumption, etc. The efficient integration of technology and automation reduces customer labor input and improves product indicators and stability.
