High efficiency vegetable seeds oil mill for extraction machine
A brief introduction to vegetable seeds oil mill for extraction machine
1.The pretreatment process of vegetable seeds oil mill for extraction machine
The oil material pretreatment process includes the cleaning section,breaking section,flaking section ,softening section and oil pressing section.
a. Create a good product environment.
b. Minimize the total fat loss ,increase oil yield and output and improve the quality of oil and cake meal
c. Comprehensively utilize impurities and offal.
d. Perfectly match extraction production line ,design different
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.

2.The extraction process of vegetable seeds oil mill for 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 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.
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 vegetable seeds oil mill for extraction machine
(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.
