1.The pretreatment process of sunflower oil production equipment china suppliers
The oil material pretreatment process includes the cleaning section,breaking section,flaking section ,softening section and oil pressing section.
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 sunflower oil production equipment china suppliers
(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.
3.The refining process of sunflower oil production equipment china suppliers
A general term for a series of processes for removing solid impurities, free fatty acids, phospholipids, gums, waxes, pigments, odors, etc. contained in vegetable oils. Enhancing the nutritional value of edible
oils has great benefits for human health.
