Problems solved by technology

[0002] 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 traditional vegetable oil production process has not been scientifically and effectively controlled due to parameters such as the temperature of each section and the concentration of alkali refining. , so that the content of linolenic acid in linseed oil is reduced, which affects the quality of the product, and its α-linolenic acid content is only about 40%.

Embodiment 1

[0025] Embodiment 1, a kind of method of refining linseed oil is characterized in that, concrete steps are as follows:

[0026] (1) Screening and making billets: After pretreatment of raw materials with vibrating screen, winnowing destoner and permanent magnet cylinder equipment, crush them with roller flaking machine to obtain billets;

[0027] (2) Steaming and frying: Pour the billet into a stainless steel cylinder steaming and frying pan for turning and frying, the temperature is controlled at 109-101°C, and the time is controlled at 14-16 minutes;

[0028] (3) Pressing: use a screw press to press, and the temperature is controlled at 68-72°C to obtain crude oil;

[0029] (4) Primary filtration: filter the pressed crude oil through a plate and frame filter, then enter the sedimentation tank, and settle at room temperature for 24-36 hours; the plate and frame filter model is 370YTX500;

[0030] (5) Secondary filtration: After being filtered by a pipeline filter, it enters t...

Abstract

The invention relates to a method for refining linseed oil. The method specifically comprises the following steps: screening and blanking; cooking; squeezing; primarily filtering; secondarily filtering; degumming; deacidifying; decoloring; filtering for the third time; deodorizing; finely filtering; and filling. According to the method, a spiral squeezer is adopted in the squeezing section, so that the squeezing efficiency is improved, the continuity is good, the utilization ratio of effective components of the raw material is improved and the smoke point of linseed oil is improved. The oil yield reaches 38.4% and the content of linolenic acid in oil reaches up to 69.76%.

Description

technical field [0001] The invention belongs to the field of oil processing, and in particular relates to a method for refining flax oil. Background technique [0002] 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. The production of oils with low linolenic acid content, such as soybean oil and peanut oil, has less impact on production, but has 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 traditional vegetable oil production process has not been scientifically and effectively controlled due to parameters such as the temperature of each section and the concentration of alkali r...
