sunflower oil press machine and peanut oil making machine

The Main raw material and Processing Of Sunflower Cooking Oil Making Machine

Flowchart of oil extraction machine:

Oil seeds →  cleaning →  softening  →  flaking  →  extrusion → drying →  to extraction workshop →DTDC →first and second evaporation →stripping tower →condenser →solvent recovery

Consumption of oil extraction machine:

Residual oil in meal	≤1% (soybean)
Solvent consumption	≤3Kg/T(6#solvent oil)
Crude oil moisture and volatile matter	≤ 0.30%
Power consumption	≤ 15KWh/T
Steam consumption	≤280Kg/T (0.8MPa)
Finished meal moisture	≤ 10-13% (adjustable)
Residual solvent in finished meal	≤ 300PPM (qualified detonated experiment

Advantage of oil extraction machine:

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 send 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.

Process of pretreatment

Cleaning device: remove the raw material peanut in various impurities, such as: iron, stones, clump, such as the plant leaf, clean up till impurity content does not exceed 0.2%.

Crushing machine: peanut is 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%.

Softening process: the purpose of softening is to adjust the moisture and temperature of oil, and make it soft.

Flaking process: rolling raw material into flakes, and the purpose is to increae surface area, destroy the peanut cell tissue, shorten the way of oil out from cake.

Extrusion: through high temperature and high pressure, soybean flakes are transfered into expanded pellet, which is easy to extract oil from, and keep high nutritive value.
