Workshop details:
leaching (extraction), evapo-separate (embryos solvent material separation), evaporation (oil and solvent separation), condensation, 
exhaust gas recycling, water recovery and other systems

Working principle:
Leaching system is an oil extraction through soaking or spraying prepressed cake by a certain organic solvent. The principle of this 
part is the different solubility of solvent.

Main process:
(1) The material (for pretreatment) is sent to rotary extraction by the scraper conveyor. The material will extracted by the solvent or mix oil. After this step, we will get meal and mix oil.
(2) Meal is sent to toaster. Through the toaster, the solvent in the meal will separate from the meal. The solvent goes to condenser and is recycled to rotary extraction.
(3) After the mix oil from the rotary extraction enters into 1st evaporator and 2nd evaporator, most of the solvent in the mix oil is 
separated. 
(4) The mix oil from 2nd evaporator goes to stripping tower and almost all the solvent is separated. From the stripping tower, we can 
get crude oil and solvent. The solvent is sent to condenser and is recycled to rotary extraction. 

C-1. oil degumming and deacidification: removing the phosphatide by adding hot water and alkalia.

2. oil decolorizing:removing the pigment by adding bleaching earth,and then use the filter to separated the wasted earth.

C-3. oil deodorization: removing the FFA  and other solid particle to get the good smell oil
