Processing line of automatic oil expeller
1. Flowchart of automatic oil expeller:
Metering →Cleaning →Magnetic separation→Destoner→Crushing →Softening →Flaking →Cooking
→Pre-pressing →go to extraction section
Second oil press
2.Pretreatment process of automatic oil expeller:
a. Cleaning device: To remove various impurities in oilseeds, such as: iron, stones, clump, such as the plant leaf, clean up till impurity content does not exceed 0.2%.
b. Crushing machine: Oilseeds are crushed into 6-8 pieces. In order to meet the requirements of crushing, the peanut is suitable for crushing with the moisture of 7% to 12%.
c. Softening Process: The purpose of softening is to adjust the moisture and temperature of oil, and make it soft.
d. Flaking process: Rolling raw material into flakes, and the purpose is to increase surface area, destroy the peanut cell tissue, shorten the way of oil out from cake.
e: Cooking process: Use steam cooking, inject direct steam and cook the flakes to meet the requirement of oil press.
f. Pre-press: Press the flakes to leave about 16%-18% in the cake. The cake will go to extraction process.
g. Second oil press: Press the cake till the oil residue is about 5%.
3. Consumption in Operation :
|Residual oil in cake||≤5%|
|Crude oil moisture and volatile matter||≤ 0.30%|
|Power consumption||≤ 15KWh/T|
|Steam consumption||≤120Kg/T (0.8MPa)|
|Mechnical impurities||≤ 0.3% (adjustable)|
|Moisture in crude oil||≤ 0.2% (qualified detonated experiment|
