Introduction to oil production line
1.The process of pretreatment
Cleaning:remove most impurities from the material, such as stones, dirt, etc., to prepare for the
next crushing process, improve crushing efficiency and extend machine life.
Crushing:after the crushing process, the material is broken into small pieces, which improves the
efficiency of the material being pressed.
Softening process:Increase the moisture content and temperature of the material, and ultimately
increase the final oil output of the material.
Flaking process:the material is pressed into pieces in this process to increase the amount of oil
discharged from the material.
Oil press:the treated oil enters the squeegee from the hopper. Under the condition of high pressure,
the embryo is continuously pushed inward by the screw press, and is pressed to finally produce oil.

Extraction→DTDC→Evaporation→Stripper→Crude oil
Extraction:The solvent enters the material and extracts the oil inside the material under a certain
temperature and pressure.
DTDC:It consists of seven layers. In the first three layers, the wet mash is heated and heated by indirect
steam to pre-dissolve and remove a large amount of solvent. In the next two layers, stripping is carried
out under the action of direct steam, the sixth layer is dried with hot air, and the seventh layer is cooled.
Evaporation:The difference between the boiling point of the oil and the solvent is used to separate the
solvent and the oil.
Stripper:The separated solvent can be dissolved in the selected paraffin or solvent and recovered.
The operating principle of the oil extraction process
(a) At a certain speed, the material is transported clockwise, and the solvent enters the material
counterclockwise, so that the solvent and the material can be contacted to the greatest extent, and the
oil yield is improved.
(b) In DTDC, in the evaporation stage, the solvent is evaporated as much as possible, and the solvent is
recycled to recycle. Then in the stripping stage, the amount of solvent in the final oil is less than the
local specified amount.
(c) The most important thing in the whole process is to control the temperature. Because the boiling
point of the solvent and oil are different, so the temperature is controlled, then the quality of the obtained
oil will be very good. Do the work of exhaust gas generated during the process of recycling and leaching to
protect the environment.
