Problems solved by technology

[0002] At present, most of the processing methods of Luzhou-flavored rapeseed oil are to directly fry the seeds after cleaning the rapeseed kernels, and then squeeze and refine the finished oil. Since the rapeseed oil slides quickly when it is overheated and pressurized, it often leaks when the oil is pressed. When the oil is not thorough enough, it will be squeezed out of the oil press with the oil cake, which reduces the oil yield, and the decolorization method is single and the adsorption capacity is poor, which not only increases the cost of investment, but also the decolorization effect is not good, and the quality of the oil is reduced

Embodiment 1

[0023] A kind of rapeseed oil processing method specifically comprises the following steps:

[0024] S1. Rapeseed treatment: use a sieve to screen out the pre-selected rapeseed, spread it flat in the sieve, and drain it. Because the silt has certain oil absorption properties, sifting out the silt can increase a certain amount of output. oil quantity;

[0025] S2. Stir-frying of rapeseed: Put the processed rapeseed into a pot heated at 80 degrees, and stir-fry until it is half mature, then reduce the temperature to 60 degrees, and stir-fry with a slow fire to avoid the rapeseed being mushy due to high heat pot;

[0026] S3. Oil extraction: quickly introduce the cooked rapeseed in S2 into the oil press for oil extraction. Since the oil molecules are most active at high temperature, more oil can be produced from the rapeseed just out of the pot;

[0027] S4. Addition of auxiliary materials: when extracting oil, add grain bran to the oil press according to the mass ratio of 18:1...

Embodiment 2

[0033] A kind of rapeseed oil processing method specifically comprises the following steps:

[0034] S1. Rapeseed treatment: use a sieve to screen out the pre-selected rapeseed, spread it flat in the sieve, and drain it. Because the silt has certain oil absorption properties, sifting out the silt can increase a certain amount of output. oil quantity;

[0035] S2. Stir-frying of rapeseed: Put the processed rapeseed into a pot heated at 90 degrees, and stir-fry until it is half mature, then reduce the temperature to 70 degrees, and stir-fry with a slow fire to avoid the rapeseed being mushy due to high heat pot;

[0036] S3. Oil extraction: quickly introduce the cooked rapeseed in S2 into the oil press for oil extraction. Since the oil molecules are most active at high temperature, more oil can be produced from the rapeseed just out of the pot;

[0037] S4. Addition of auxiliary materials: During oil extraction, add rice bran to the oil press at a mass ratio of 20:1. When pres...

Embodiment 3

[0043] A kind of rapeseed oil processing method specifically comprises the following steps:

[0044] S1. Rapeseed treatment: use a sieve to screen out the pre-selected rapeseed, spread it flat in the sieve, and drain it. Because the silt has certain oil absorption properties, sifting out the silt can increase a certain amount of output. oil quantity;

[0045] S2. Stir-frying of rapeseed: put the processed rapeseed into a pot heated at 100 degrees, and stir-fry until it is half mature, then reduce the temperature to 80 degrees, and stir-fry with a slow fire to avoid the rapeseed being mushy due to high heat pot;

[0046] S3. Oil extraction: quickly introduce the cooked rapeseed in S2 into the oil press for oil extraction. Since the oil molecules are most active at high temperature, more oil can be produced from the rapeseed just out of the pot;

[0047] S4. Addition of auxiliary materials: when extracting oil, add rice bran to the oil press according to the mass ratio of 22:1...

Abstract

The invention discloses a processing method of rapeseed oil. The processing method comprises the steps of rapeseed treatment, parching of rapeseed, oil expression, addition of auxiliary materials, dephosphorization treatment, purification of rapeseed oil, decolorization, deodorization and the like. Sediments in the rapeseed are sifted out before parching and a proper amount of cavings is added into the rapeseed when oil is expressed; the sediments have certain oil absorption and the oil pump capacity can be improved by sifting out the sediments; meanwhile, the cavings can slow down the slidingof the rapeseed; the rapeseed oil is expressed more thorough, so that the oil pump capacity is effectively improved. During the dephosphorization treatment, a table salt solution is added into the crude oil; table salt has the advantages that harmful components such as erucic acid and jervine in the crude rapeseed oil to a human body can be weakened, and further the quality of the oil is increased; in addition, water-soluble silicate and active white earth are synergized together during decolorization; due to complementary characteristics of the two substances, as well as higher adsorption activity to phospholipids, trace metals and soaps, the oil color can be improved; besides, the method has the advantages that the use of white earth can be effectively saved and the investment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of rapeseed oil, in particular to a method for processing rapeseed oil. Background technique [0002] At present, most of the processing methods of Luzhou-flavored rapeseed oil are to directly fry the seeds after cleaning the rapeseed kernels, and then press and refine the finished oil. Since the rapeseed oil slides quickly when it is overheated and pressurized, it often leaks when the oil is pressed. When the oil is not thorough enough, it will be squeezed out of the oil press with the oil cake, which reduces the oil yield, and the decolorization method is single and the adsorption capacity is poor, which not only increases the cost of investment, but also has poor decolorization effect and reduces the quality of the oil. For this reason, we propose a kind of rapeseed oil processing method, in order to solve the problem mentioned in the above-mentioned background technology. Contents of the invention [...
