Company introduction
Xinxiang Chemical company is mainly focused on all kinds of seed oil extraction line . Our company has established about 30 years . We have got much more experience in this field . And On the technology ,we cooperate with our Industry .University .And we have the professional engineer .And our workers all
work with their certification .

Main method of soya bean cooking process
We choose the leaching method to extract soybean oil .
Why we choose the leaching method to extract soybean oil ?
The soybean extraction oil rate is 12-18 % . All the seed oil extraction rate is not up 25 % .
We all choose the leaching method to extract oil .
Pretreatment of soya bean oil process
The soybean is processed by magnetic selector - vibrating screen of wiping off the big and small impurities - specific-gravity stoner of cleaning the stones - Crush the soybean ,which make the soybean
5pcs - Soften the soybean ,which add soybean moisture - flaking the soybean - bulking the soybean ,which make oil come out Easily .
Leaching soybean of soybean oil process What is the leaching method ?
Extraction is a chemistry way to extract oil from soybean . It makes use of Solvent Extraction Principles ,which makes Number 6 solvent oil come into soybean cake .Then oils and fats is dissolved from Mixed oil.When we finished the soybean pretreatment , the moisture of soybean need to be 90% So we must control the moisture before sending the soybean to extractor . The soybean is processed by oil fatty extracted - wet meal desolvation - mixed oil evaporation - stripping by steam - solvent recovery .

Soybean cooking oil refinery What is the crude oil ?
The oil is processed by presser and leaching ,not refinery .
What is the refinery ?
We wipe off the impurities from the crude oil is called refinery .The component of crude oil is made of Fatty acids in triLDycerides ,phospholipid , free fatty acid, pigment , peroxide , waxiness , and other machanical impurities .
The main process of refinery
Crude oil - degumming - decolorization - deodorization -deacidification - dewaxing - fractionation .
Degumming
Degumming mainly remove phospholipid , The method is aqueous method and heating method ,and add acid method .
Decolorization
The process is that we make use of sorbent ,removing the pigment and other impurities ,then filter the sorbent and impurities ,we can get clear oil
The request of sorbent
1. Name activated carclaLDte
2. Temperature of adsorption 80~ 110 degree we control 80~ 85 degree
3. Speed of stir less than 80r/min
4. Time of decolorization 10~ 30 min
Sorbent dosage : carclaLDte is 1%~ 3 % of oil weight
Deodorization
Vacuum deodorization steam method
Mainly make use of big difference of smelly substance and volatility of triLDyceride , At the high temperature and high vacuum ,we make the smelly substance in the deodorizator with the vapour coming out from the deodorization container .
