Rapeseed oil extraction production line
A complete set of machines for extracting rapeseed oil by solvent extraction. First, the rapeseed is pre-pressed, and the pre-pressed rapeseed cake is extracted by leaching. The machine process mainly includes rapeseed pretreatment, rapeseed oil pre-pressing, rapeseed oil extraction and rapeseed oil extraction. Refined four parts. After refining, rapeseed oil that meets national standards can be obtained and sold on the market. Next, let’s take a look at the detailed process of producing canola oil by prepress leaching extraction.
1. From the production process, it can be divided into pressed rapeseed oil and leached rapeseed oil.
2. According to whether the raw material is genetically modified, it can be divided into genetically modified rapeseed oil and non-genetically modified rapeseed oil.
3. According to the erucic acid content of the fatty acid composition, it can be divided into general rapeseed oil and low erucic acid rapeseed oil.
 
Generally dark yellow or brown. Rapeseed oil contains 0.4-1.0% arachidic acid, 14-19% oleic acid, 12-24% linoleic acid, 31-55% erucic acid, and 1-10% linolenic acid. From the perspective of nutritional value, the human body can digest and absorb rapeseed oil as high as 99%, and it has a gallbladder function. When the liver is in a pathological state, brassicone can also be metabolized by the body normally. In addition, rapeseed oil contains a small amount of substances such as erucic acid and sinigrin, which are generally believed to be harmful to the growth and development of the human body. If it can be eaten in conjunction with high-quality edible oil rich in linoleic acid, its nutritional value will be improved.
Pretreatment of rapeseed oil extraction production line
Rapeseed pretreatment refers to the cleaning of rapeseed before the production of rapeseed oil, including a series of treatments such as screening of rapeseed, softening, pressing, steaming and frying. The purpose is to remove impurities in the rapeseed and adjust the internal structure of the rapeseed to make it suitable for pre-pressing. In order to improve the pre-pressing efficiency of rapeseed oil. Rapeseed pretreatment equipment used includes cleaning equipment (magnetic separator, cleaning screen, stoner), flaking machine and steamer. Cleaning and other machine parts can be selected according to the type of rapeseed impurities and the amount of rapeseed impurities, or manual equipment can be used instead of mechanical equipment to reduce investment costs, but it will also affect the pretreatment effect.
  Pre-pressing section of rapeseed oil extraction production line
Pre-pressing of rapeseed oil extraction production line; mainly to press the pre-treated rapeseed with a pre-pressing machine. After pre-pressing, most of the oil in the rapeseed is extracted, and the residual oil in the rapeseed cake is generally 15%-18%. The rapeseed cake needs to be transported to the extraction workshop to extract the rapeseed oil in the cake.
The extraction section of the rapeseed oil extraction production line
The rapeseed cake after pre-pressing part of the oil by the pre-pressing machine is sent to the extractor by the conveyor, and the pre-pressing cake is soaked in countercurrent with No. 6 solvent oil to fully dissolve the oil components in the pre-pressing cake into the solvent oil . The solvent oil dissolved with rapeseed oil is called mixed oil, and finally the mixed oil is fully separated from the solid oil cake. The rapeseed meal is dried in an off-line steamer to remove the solvent, and the solvent is cooled and recovered for reuse. The mixed oil passes through a multi-effect evaporator, evaporates and separates the rapeseed oil component, and the solvent oil is cooled and separated for reuse. The separated crude oil goes to the refining workshop. Complete the complete process of extracting rapeseed oil with a grease extraction machine.
Zhengzhou Dayang Oil Chemical Equipment Co., Ltd. produces various types of rapeseed oil extraction production lines, with a processing capacity of 30 tons/day---2000 tons/day.
Oil refining section of rapeseed oil extraction production line
Whether it is rapeseed oil obtained by pre-pressing or leaching, it is called crude oil. Crude oil contains harmful impurities that are harmful to the human body and some useless impurities, which need to be removed by refining. The refining process of rapeseed oil mainly includes four parts: degumming, deacidification, decolorization and deodorization. After the rapeseed oil is refined, all the indicators meet the national standards and can be sold on the market.
 
The above is the detailed process of producing rapeseed oil by pre-pressing extraction method. In addition to the production of rapeseed oil, there are pressing method and direct leaching extraction method, but the specific rapeseed oil production method needs to be based on the quality of rapeseed and the processing amount of rapeseed. , market requirements for rapeseed oil, and investment costs and other factors to choose a rapeseed oil extraction machine. To choose a suitable rapeseed oil production method, these factors need to be considered comprehensively and carefully analyzed.
