B,the pretreatment is a very important section,it will directly affect the oil making effect.
The Pretreatment Machines as follows:
2.Leaching
The leaching process refers to use a kind of solvent that can dissolve the oil ,through humidify the oil and molecular diffusion,then extract the oil from the castor seed flake.
The Edible Oil leaching process flow chart and the Edible Oil production leaching machines as follows:
3.Refining
A,the first step is degum,add the phosphoric acid to the crude oil,the weigLD is 1â°of the oil's,the concentration is 85%.stir for 5 minutes then add hot water 80°C, weigLD is 4%of the oil.after stilling 120 minutes, let off the residue.
B,the second step is deacidify,as the castor oleic value is generally less than 6, so have to use a high concentration of lye.adding the lye into the oil(about 80°C)quickly,then stir,the still about 4 to 5 hours.at last let off the soapstock.
C,the third step is washing,heat the oil about 85°C,then add the same hot water that weigh 20% of oil ,then stir, still about 40 minutes is ok, generally washing 2 times.
D,the forth step is dry decoloring,The drying temperature keep 105â110 ° C, the vacuum of 0.08â0.094Mpa is a dry qualification.it have to use the dry acid clay and activated carbon, and the bleaching temperature keep about 100â110 ° C.at last filtrate after cooled to 70-80°C,then will get the refined castor oil.
