Problems solved by technology

These oil production methods are all oil production under high temperature and high moisture conditions, which causes the color of rapeseed oil and cake obtained by hot pressing to deepen and deteriorate in quality, and it is easy to destroy the rich nutrients in this kind of high-quality rapeseed. The quality of edible vegetable oil is still not good, and there is still a lot of room for improvement in the existing technology

Embodiment 1

[0029] Oil is prepared according to the method of the present invention with the high-oil high-quality rapeseed of the Youyan 817 rapeseed variety that Guizhou Province Rape Research Institute has researched, and the steps are as follows:

[0030] (1) The raw materials are sun-dried to reduce the moisture to 8%, and preliminarily sorted and screened.

[0031] (2) The rapeseed is air-selected, de-stoned and selected to remove impurities in the rapeseed.

[0032] (3) Low-temperature drying and tempering: On the second day after the raw materials are purchased and stored in the warehouse, use a low-temperature grain dryer to dry and temper the rapeseed at a low temperature of 50-55 °C, and slowly reduce the moisture to 6. %; The drying and tempering time at low temperature is 5 hours.

[0033] (4) Dehulling and separation of high-quality seeds with high oil content and separation of skins and kernels: The separation equipment uses the principles of roller crushing, vibration, sc...

Embodiment 2

[0038] Oil is prepared according to the method of the present invention with the high-oil and high-quality rapeseed of the Youyan No. 10 rapeseed variety that is researched by the Rape Research Institute of Guizhou Province, and the steps are as follows:

[0039] (1) The raw materials are sun-dried to reduce the moisture to 10%, and preliminarily sorted and screened.

[0040] (2) The rapeseed is air-selected, de-stoned and selected to remove impurities in the rapeseed.

[0041] (3) Low-temperature drying and tempering: On the third day after the raw materials are purchased and stored in the warehouse, the rapeseed is dried and tempered at a low temperature at a low temperature of 45-50 °C with a low-temperature grain dryer, and the moisture is slowly reduced to 7%; low temperature drying and tempering time is 7 hours.

[0042] (4) Dehulling and separation of high-quality seeds with high oil content and separation of skins and kernels: The separation equipment uses the princip...

Embodiment 3

[0047] Oil is prepared according to the method of the present invention with the high-oil high-quality rapeseed of the Youyan 50 rapeseed varieties that are researched by the Rape Research Institute of Guizhou Province, and the steps are as follows:

[0048] (1) The raw materials are sun-dried to reduce the moisture to 11%, and preliminarily sorted and screened.

[0049] (2) The rapeseed is air-selected, de-stoned and selected to remove impurities in the rapeseed.

[0050] (3) Low-temperature drying and tempering: On the second day after the raw materials are purchased and stored in the warehouse, use a low-temperature grain dryer to dry and temper the rapeseed at a low temperature of 50-55 °C, and slowly reduce the moisture to 7. %; The drying and tempering time at low temperature is 9 hours.

[0051] (4) Dehulling and separation of high-quality seeds with high oil content and separation of skins and kernels: The separation equipment uses the principles of roller crushing, v...

Abstract

The invention discloses a method for preparing oil from high-quality rapeseeds with high content of oil under low-temperature and low-moisture conditions. The method comprises the following steps: selecting raw materials, cleaning and carefully choosing the raw materials, drying and conditioning at a low temperature, conditioning, peeling the rapeseeds, separating peels from kernels, conditioning at a low temperature, squeezing at a low temperature and carrying out pure physical filtration and fine filtration. High-quality natural high-grade and high-end oil is obtained from the high-quality rapeseeds with high content of oil under low-temperature and low-moisture pure physical process technical conditions, compared with commercially available leaching oil and hot-pressed oil, the rapeseed oil is natural, clear and transparent, has golden color and is rich in natural vitamin E and phytosterols; the content of protein in the cakes is increased and the biological activity of protein in rapeseed meals is ensured; the method has the advantages of low energy consumption, low cost and no pollutants.

Description

technical field [0001] The invention relates to the technical field of rapeseed oil extraction, in particular to a method for producing oil from high-quality rapeseed with high oil content under low-temperature and low-moisture conditions. Background technique [0002] With the improvement of living standards, people's demand for edible vegetable oil is increasing year by year. In recent years, the amount of imported oil and oilseeds in my country has increased from 4.614 million tons in 2000 to 20.889 million tons in 2010, an increase of 535% in ten years, with an average annual growth rate of 35.3%. The self-sufficiency rate of edible vegetable oil has dropped from 60% at the beginning of this century to about 37% at present. The self-sufficiency rate of edible vegetable oil is quite lacking, especially the demand for high-end edible vegetable oil is quite scarce, and there is an urgent need to develop and produce high-end edible vegetable oil suitable for the lives of ou...
