For the high oil content material sesame seed ,it will need pre-press,then the cake go to solvent extraction workshop,oil go to refining. As a salad oil, it is used in mayonnaise, salad dressings, sauces, and marinades. As a cooking oil, it is used for frying in both commercial and home cooking.
1.The pretreatment process of sesame oil extraction machine 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 sesame oil extraction machine production line
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. 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 sesame oil extraction machine 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.
Deacidification and Degumming:This step is mainly to remove the excess acid in the grease.
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.
Deodorization:Deodorization of oil and fat not only removes odor substances in oil, but also improves the safety of oils and fats.
Filteration:Miscella mixed by oil and clay from bleaching tower is pumped into decolorizing filter.
Dewaxing process:Bleached oil enter into crystallizing tank through heat exchanger and begin the cooling crystallization process.
