Problems solved by technology

[0003] With the promotion of "double-low" rapeseed varieties, when the content of glucosinolates in whole seeds gradually decreases, the proportion of glucosinolates in the seed coat to the content of whole seeds has increased. The seed coat of the seed has not been peeled off, so that the oil can be directly produced without peeling off the skin. In addition to increasing the color of the crude oil and reducing the quality of the oil, it will also bring harmful substances in the seed coat into the oil, and it will also affect the further processing of rapeseed meal. The development and utilization of rapeseed dehulling oil production has become the consensus of the industry, therefore, a method for preparing dehulled rapeseed oil is proposed

Embodiment 1

[0021] A preparation method of dehulled rapeseed oil, comprising the steps of:

[0022] S1. Screen and remove impurities. Select a certain amount of rapeseed according to the storage capacity of the pre-used equipment for screening. After removing impurities, make the rapeseed contain less than 0.5% of impurities, and then transfer the rapeseed to a container for cleaning. Then put it into the conditioning machine, adjust the water content of rapeseed to 8% and set aside;

[0023] S2, peeling, the rapeseed after conditioning in S1 is transferred to a peeling machine for peeling treatment;

[0024] S3, separation, the rapeseed after the peeling treatment in S2 is separated from the skin and kernel by winnowing, the peeling rate is ≥ 80%, the skin content in the kernel is ≤ 5%, the kernel content in the skin is ≤ 1%, and the obtained skin For other purposes, such as leaching oil, as a fungal culture medium or as a fuel, the obtained rapeseed kernels are ready to be put into a c...

Embodiment 2

[0031] A preparation method of dehulled rapeseed oil, comprising the steps of:

[0032] S1. Screen and remove impurities. Select a certain amount of rapeseed according to the storage capacity of the pre-used equipment for screening. After removing impurities, make the rapeseed contain less than 0.5% of impurities, and then transfer the rapeseed to a container for cleaning. Then put it into the conditioning machine, adjust the water content of rapeseed to 9% and set aside;

[0033] S2, peeling, the rapeseed after conditioning in S1 is transferred to a peeling machine for peeling treatment;

[0034] S3, separation, the rapeseed after the peeling treatment in S2 is separated from the skin and kernel by winnowing, the peeling rate is ≥ 80%, the skin content in the kernel is ≤ 5%, the kernel content in the skin is ≤ 1%, and the obtained skin For other purposes, such as leaching oil, as a fungal culture medium or as a fuel, the obtained rapeseed kernels are ready to be put into a c...

Embodiment 3

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

[0042] S1. Screen and remove impurities. Select a certain amount of rapeseed according to the storage capacity of the pre-used equipment for screening. After removing impurities, make the rapeseed contain less than 0.5% of impurities, and then transfer the rapeseed to a container for cleaning. Then put it into the conditioning machine, adjust the water content of rapeseed to 9% and set aside;

[0043] S2, peeling, the rapeseed after conditioning in S1 is transferred to a peeling machine for peeling treatment;

[0044] S3, separation, the rapeseed after the peeling treatment in S2 is separated from the skin and kernel by winnowing, the peeling rate is ≥ 80%, the skin content in the kernel is ≤ 5%, the kernel content in the skin is ≤ 1%, and the obtained skin For other purposes, such as leaching oil, as a fungal culture medium or as a fuel, the obtained rapeseed kernels are ready to be put into a c...

Abstract

The invention discloses a preparation method of peeled rapeseed oil. The preparation method comprises the following steps of sorting to remove impurities, peeling, separating, flaking, steaming and frying, mixing, pressing, filtering, and settling, so as to obtain a finished product. The prepared peeled rapeseed oil has the advantages that multiple nutrient ingredients in rapeseed are maintained, and the oil product is more fragrant. The preparation method has the advantages that the harmless and pollution-free are realized, the pure physical pressing is adopted, the industry requirement is met, and the economic and social benefits are obvious; meanwhile, the pigment is reduced along with the peeling, the content of crude protein in the peeled rapeseed oil is effectively improved, the anti-nutrient factors of sinapine, tannin and the like in meal are reduced, and the utilization value of the meal is improved.

Description

technical field [0001] The invention relates to the technical field of rapeseed oil, in particular to a method for preparing dehulled rapeseed oil. Background technique [0002] Rapeseed is the most important oil crop in my country. Rapeseed is rich in nutrients, especially the rapeseed that grows on the Qinghai-Tibet Plateau in my country. It is of good quality, pure natural, and pollution-free. It has many unique advantages such as high altitude, long sunshine, air, water, and soil. Its oil content Generally around 35-42%, crude protein content is 20-27%, rich in various fatty acids, vitamin E, physiologically active substances, amino acids and other nutrients, but more than 90% of rapeseed whole seeds contain phytic acid, pigments, Tannin, saponin, etc. are all present in the seed coat, and sinapine is also mostly present in the seed coat. Although the seed coat also contains about 16% oil and 18-20% crude protein, the contained crude fiber is as high as 30-34%. [0003]...
