Vegetable oil press machine

Pretreatment and prepressing section is a very important section before extraction. It will directly affect extraction effect. Our vegetable oil press machine is used to process various kinds of oilseeds such as peanuts, sunflower, soybean, rapeseed, cottonseed, rice bran ,and palm fruit, etc. And our vegetable oil press machine capacity can becustomized. Prepress/pretreament process can be devided to several parts, cleaning, delinting, husking/dehulling/shelling, drying, crushing, softening, flaking, cooking etc.

1.Cleaning: Cleaning is a series of operation to remove impurities in oil seeds.
2. Husking/dehulling/shelling: Oil seeds like peanut, sunflower seed, cotton seed, palm kernel, etc, have hard shells above nuts. Husking/dehulling/shelling is to seperate shells from nuts.
3. Drying: Reducing oil seed moisture to proper moisture is drying.
4. Crushing:  For big-size oil seeds, crushing reduces its size to benefit flaking, while for prepressed cake, crushing turns cake to proper size and creats better oil yeild for second press or solvent extraction. Crushing is always necessary for soybean, peanut, palm kernel, coconut copra, tung oil seed, etc.
5. Softenning: Softenning adjusts moisture and temperature of oil seeds, softens and increases plasticity of oil seeds.
6. Flaking: Flaking damages oil cells, increases oil surface, and shortens the oil outflowing distance, which benefits oil extraction and impoves cooking efficiency.
7. Puffing: Puffing turns oil seeds(cracked, flaked, or whole seed) to polyporous matters, which improves solvent permeability in extraction and increases leaching rate.
8. Cooking: Cooking is to wet, heat, steam and to cook flakes to change the internal structure of flakes, including destorying cells, protein solidification and denaturation, etc. All these changes makes oil easy to isolate and also enhance crude oil quality.
9. Pressing/prepressing: Pressing/prepressing is to press oil from oil seeds or cakes. In general, there are several oil press machine for this step.
