Soybean oil line make cold pressed oil Company image
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 parameter of soybean extraction
The general soybean oil extraction rate 12 %- - 18 % Transgenosis soybean extraction oil rate 18 %- 21% Protein of general extracted 50 % Protein of transgenosis soybean extracted 65 -70 % Oil extracted rate of soybean 98 % After refinery, oil in the cake 1 %
Main fatty acid of soya bean
Stearic acid 2-5 % palmitic acid 7-10% linoleic acid 5-9% linoleic acid 50-60% oleic acid 22-30% arachidic acid 1-3%
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 4-5pcs - 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 .
Material embryos→Extraction→Wet meal→Evaporation→Cooling→Product meal packing ↓ Mixed oil→Filter→Negative pressure evaporation → Crude oil ↓ 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 triglycerides , 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 mainly remove phospholipid ,
The method is aqueous method and heating method ,and add acid method .
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 carclazyte
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 : carclazyte is 1%~ 3 % of oil weight
Vacuum deodorization steam method Mainly make use of big difference of smelly substance and volatility of triglyceride , At the high temperature and high vacuum ,we make the smelly substance in the deodorizator with the vapour coming out from the deodorization container .
