A brief introduction to oil production line

1.The pretreatment process of oil production line 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 oil production line

(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→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.

3.The refining process of oil production line

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.

(1)Deacidification and degumming

This step is mainly to remove the excess acid in the grease. If the peptized impurities of the oil are not removed, the excessive emulsification will occur during the alkali refining process, so that the oil soap can not be separated well, affecting the refining and Oil quality.

(2)Decolorization

The decolorization process greatly enhances the oxidation stability of the oil, and this process also has a great influence on the subsequent deodorization process of the oil. In this process, the oxide is completely removed, and the trace amount of metal, residual soap and residual fat are removed in a maximum amount, and a part of the pigment is moderately removed.

(3)Deodorization

Deodorization of oil and fat not only removes odor substances in oil, but also improves the smoke point of oils and fats, improves the flavor of edible oils, and effectively improves the safety of oils and fats.

(4)Filteration

Miscella mixed by oil and clay from bleaching tower is pumped into decolorizing filter, then enters into fine filter, in which clay and fixed impurities are blocked.(5)Dewaxing processBleached sunflower seed oil enter into crystallizing tank through heat exchanger and begin the cooling crystallization proces,this process is controlled by the computer through the parameters preestablished,the computer controls temperature of circulating water in the frozen coil to comand cooling speed of the oil,thereby receive the best crystal result.
