Such a cooking oil press production line can produce high quality pressed oil, but the residual oil rate is about 6-7%. If you want to get more oil out and the economy allows, you can choose pre-press and solvent extraction method.

After pre-pressing, the residual oil rate is about 15%, and then through solvent extraction, the residual oil rate can achieve 1%. The oil seed cakes enter the solvent extractor. The extractor fully mixes the n-hexane with the oil by spraying n-hexane, so as to extract the oil from the oil cakes, and the obtained mixed oil will evaporate the n-hexane from the oil by evaporative stripping. The evaporating and stripping equipment includes a first evaporator, a second evaporator, a flash box, etc. Finally, the solvent in the meal is evaporated through the evapo-separated machine or DTDC, and finally the solvent is recovered and recycled.

If you want the oil to be refined, we also have cooking oil refining machine with different capacity. Small scale cooking oil refinery machines have electrical type and oil conduction type. Refining can enhance oil storage stability, improve oil flavor, improve grease color, and provide raw materials for deep-processed oil products. After refining, your cooking oil can be sold to the market directly.(Recommend reading: Sunflower oil processing plant)

The refining process of cooking oil refinery machine:

1. Degumming: The process of removing peptized impurities from the crude oil is called degumming.

2. Deacidification: There is always a certain amount of free fatty acids in vegetable oils, deacidification is to reduce the oily fatty acids in the oil.

3. Decolorization: Oil decolorization commonly used adsorption decolorization method. The principle of the adsorption decolorization method is to use an adsorbent with strong adsorption such as activated clay to remove the adsorbed pigments and impurities while filtering and removing the adsorbent.

4. Deodorization: removal of small molecule odors in oil.
