Problems solved by technology

[0002] Soybean is the main food crop in my country. Soybean contains a lot of oil. Soybean is also the main source of edible oil. When soybean oil is processed, it is mainly processed by high-temperature extrusion, but the oil yield is low. The oil yield can only reach about 75%, and high-temperature oil extraction will destroy the unsaturated fatty acids in soybean oil, which will affect the nutritional value of the oil.

Embodiment 1

[0011] A soybean oil processing method for improving the oil yield, comprising the following steps: (1), using a crusher to crush soybeans into 40-mesh particles; (2), putting the crushed soybeans into a steamer and steaming at 130°C for 35 minutes, Then add salt of 1% of the total weight of soybeans to the soybeans, and mix well; (3), put the steamed soybeans into a centrifuge and centrifuge at 1000r / min for 10 minutes; (4), then mix the centrifuged soybeans with absolute ethanol Add a distillation device to carry out vacuum distillation, carry out distillation at 90° C., and separate the distillate to obtain soybean oil.

[0012] The processing speed of the soybean oil processed by the method is fast, the oil yield reaches 95%, and the oil yield is much higher than that of the conventional method, and the nutritive substances of the soybean oil are not destroyed, and the soybean oil has high quality.

Embodiment 2

[0014] A soybean oil processing method for improving the oil yield, comprising the following steps: (1), crushing soybeans into granules by using a crusher; (2), steaming the crushed soybeans in a steamer at 140°C for 30 minutes, and then Add 0.5% salt of the total weight of soybeans to the soybeans, and mix well; (3), put the steamed soybeans into a centrifuge and centrifuge at 1200r / min for 8 minutes; (4), then add the centrifuged soybeans and absolute ethanol The distillation device performs vacuum distillation at 87° C., and separates the distillate to obtain soybean oil.

[0015] The oil yield of soybean oil processed by this method reaches 94.5%, which is also significantly improved compared with other methods.

Abstract

The invention relates to a soybean oil processing method capable of improving oil yield. The method comprises the steps of (1) crushing soybeans into particles by using a crusher; (2) putting the crushed soybeans into a steamer, steaming for 30-40 minutes at 125-140 DEG C, then adding salt which is 0.5-2% of the total weight of the soybeans into the soybeans, and uniformly mixing; (3) adding the steamed soybeans into a centrifuge, and performing centrifuging treatment for 6-10 minutes at a rotating speed of 800-1200r / min; (4) then adding the centrifuged soybeans and absolute ethyl alcohol into a distillation device for reduced-pressure distillation, performing distillation at 85-92 DEG C, and performing oil-water separation on a distillate to obtain soybean oil. The processing method disclosed by the invention is capable of greatly improving the oil yield of the soybeans.

Description

technical field [0001] The invention belongs to the field of vegetable oil processing, and in particular relates to a soybean oil processing method for improving oil yield. Background technique [0002] Soybean is the main food crop in my country. Soybean contains a lot of oil. Soybean is also the main source of edible oil. When soybean oil is processed, it is mainly processed by high-temperature extrusion, but the oil yield is low. The oil yield can only reach about 75%, and the use of high-temperature oil extraction will destroy the unsaturated fatty acids in soybean oil and affect the nutritional value of the oil. Contents of the invention [0003] The purpose of the present invention is to provide a soybean oil processing method that improves the soybean oil yield, improves the soybean oil yield and ensures the quality of the oil. [0004] The present invention is realized through the following technical solutions: [0005] A soybean oil processing method for improvin...
