Embodiment 1

[0032] A preparation method of rapeseed oil, comprising the following steps:

[0033] (1) Cleaning: first use a windmill to remove the ash debris lighter than the rapeseed, and then sieve it with a coarse and fine sieve to remove the debris larger and smaller than the rapeseed, and then put the rapeseed into the water and lightly clean it with your hands. Knead gently for 5 minutes to remove the sludge covering the surface of the rapeseed, and then remove the rapeseed;

[0034] (2) Stir-fried seeds: Put the fished rapeseed into the interlayer pot, control the initial frying temperature to 150°C for 30 minutes, then adjust the temperature to 100°C, and after frying for 25 minutes, adjust the temperature to 80°C and stir-fry When the moisture content of the rapeseed is 8%, it can be out of the pot;

[0035] (3) Grinding: put the roasted rapeseed into the grinder, add water to grind, the amount of water is 30% of the weight of the rapeseed, and add 0.4% of the salt in the water,...

Embodiment 2

[0041] A preparation method of rapeseed oil, comprising the following steps:

[0042] (1) Cleaning: first use a windmill to remove the ash debris lighter than the rapeseed, and then sieve it with a coarse and fine sieve to remove the debris larger and smaller than the rapeseed, and then put the rapeseed into the water and lightly clean it with your hands. Knead gently for 10 minutes to remove the sludge covering the surface of the rapeseed, and then remove the rapeseed;

[0043] (2) Stir-fried seeds: Put the fished rapeseed into the interlayer pot, control the initial frying temperature to 200°C for 20 minutes, then adjust the temperature to 120°C, and after frying for 15 minutes, adjust the temperature to 100°C and stir-fry When the moisture content of the rapeseed is 12%, it can be out of the pot;

[0044] (3) Grinding: add camellia seed kernel and corn germ to the rapeseed after frying and mix evenly, add water and grind, the consumption of water is 40% of rapeseed weight,...

Embodiment 3

[0050] A preparation method of rapeseed oil, comprising the following steps:

[0051] (1) Cleaning: first use a windmill to remove the ash debris lighter than the rapeseed, and then sieve it with a coarse and fine sieve to remove the debris larger and smaller than the rapeseed, and then put the rapeseed into the water and lightly clean it with your hands. Gently knead for 8 minutes to remove the sludge covering the surface of the rapeseed, and then remove the rapeseed;

[0052] (2) Stir-fried seeds: Put the fished rapeseed into the interlayer pot, control the initial frying temperature to 180°C for 25 minutes, then adjust the temperature to 110°C, and after frying for 20 minutes, adjust the temperature to 90°C and stir-fry When the water content of the rapeseed is 10%, it can be out of the pot;

[0053] (3) Grinding: Add camellia seed kernels and corn germ to the fried rapeseed and mix evenly, then send it into the grinder, add water to grind, the amount of water is 35% of th...

Abstract

The invention discloses a preparation method of rapeseed oil and belongs to the technical field of oil processing. The preparation method comprises the steps as follows: firstly, rapeseed is cleaned, the rapeseed covered with water after cleaning is fried directly in a rapeseed frying process with a sectional type gradual cooling method, and the fried rapeseed is ground to obtain preliminary ground crude oil and rapeseed residues; the granularity and moisture of the rapeseed residues are adjusted, then the rapeseed residues are fed into an agitation tank for leaching, and leached crude oil and rapeseed residues are obtained; the preliminary ground crude oil and the leached crude oil are mixed to obtain mixed crude oil; the mixed crude oil is refined to obtain finished rapeseed oil. The rapeseed oil leaching efficiency is high after processing with the preparation method, the inherent flavor, aroma and nutrient substances of the rapeseed oil are kept, and the prepared rapeseed oil is pure and higher in quality.

Description

technical field [0001] The invention relates to the technical field of edible oil processing, in particular to a preparation method of rapeseed oil. Background technique [0002] Rapeseed oil is commonly known as rapeseed oil, also known as rapeseed oil. It is sweet, pungent, and warm in nature. It can moisten dryness and kill insects, disperse fire pills, and reduce swelling and poison. The human body has a high absorption rate of rapeseed oil, which can reach 99%. Therefore, the unsaturated fatty acids such as linoleic acid and vitamin E and other nutrients contained in it can be well absorbed by the body, and have certain effects of softening blood vessels and delaying aging. Since the raw material for oil extraction is the seed of a plant, it generally contains a certain amount of seed phospholipids, which is very important for the development of blood vessels, nerves, and brain. Rapeseed oil contains little or no cholesterol, so people who control their cholesterol in...
