Problems solved by technology

[0004] In the traditional vegetable oil production process, the steaming temperature and pressing temperature of the oil are not controlled as an important parameter, and there is no corresponding measurement and control system in the production equipment. In the production process, the temperature is very important for rapeseed oil. Oils with low linolenic acid content, such as soybean oil and peanut oil, have less impact on production, but have a greater impact on linseed oil
α-linolenic acid in linseed oil is an unsaturated fatty acid that is easily oxidized by heat. Therefore, the linseed oil produced by the tra

Abstract

The invention belongs to the field of oil plant processing, and more specifically relates to flaxseed oil production technology. The flaxseed oil production technology comprises following steps: pre-treatment, stir frying, squeezing, primary filtering, secondary filtering, refining, degumming, degreasing and dewatering, dewaxing, and filling; wherein in the process of degumming, 0.05 to 1 mass part of a phosphoric acid solution is added into a refining tank, uniform stirring is carried out, settlement is carried out for 1 to 2h; 0.05 to 1 mass part of a sodium hydroxide solution is added intothe refining tank, uniform stirring is carried out, and settlement is carried out for 10 to 14h; at last, 0.05 to 1 mass part of a Sodium Chloride solution is added into the refining tank, uniform stirring is carried out, and settlement is carried out for 10 to 14h; after settlement, refining tank bottom solution is pumped out to obtain degummed flaxseed oil. According to the technology, hydrationdegumming is adopted for flaxseed oil degumming, phosphoric acid, Sodium Hydroxide, and Sodium Chloride are added into the refining tank for hydration degumming, so that non-glyceride impurity content is low, the produced flaxseed oil is excellent in mouthfeel, the color is bright yellow, the flaxseed oil is clear liquid, and product quality is improved.

Description

Technical field: [0001] The invention belongs to the field of oil processing, and in particular relates to a production process of linseed oil. Background technique: [0002] Flaxseed oil is the oil extracted from flaxseed. Flaxseed, also known as flaxseed, is the seed of flax, an annual or perennial herb of the family Linaceae and the genus Flax. Linseed oil is the oil obtained by pressing the seeds of the oil crop flax. Flaxseed oil contains linoleic acid, an omega-6 fatty acid, but unlike most vegetable oils, it is dominated by another essential fatty acid, alpha-linolenic acid (ALA ), an omega-3 fatty acid. The production process of oil is generally divided into pressing method and leaching method (refining method). [0003] The pressing method, also known as the "physical pressing method", is to use external force to squeeze out the oil in the oil, without using other chemical solvents, etc., to avoid the residue of organic solvents in the oil. The pressing producti...
