Embodiment 1

[0037] Desolvation and conditioning of soybean protein concentrate

[0038] After removing impurities, soybeans are sent to the drying tower for medium temperature conditioning, and after cooling, they are crushed into 4 to 6 petals by the crusher, and the bean skins are selected by the air separator. Generally, according to the difference in protein content, the skin content index is required to be 1% to 1%. About 5%. The peeled soybean petals enter the softening process to soften. The softening temperature is 75°C and the softening time is about 30 minutes. Embryo, in order to maximize the extraction of the fat in the embryo, the green embryo needs to be dried to remove part of the water and change the distribution of oil in the embryo. Then it is sent to the degreasing extractor for degreasing, and the moisture content of the embryo entering the degreasing extractor is required to be less than 8%, the temperature is 60°C, and the powder degree is less than 10%.

Embodiment 2

[0049] Desolvation and conditioning of dephenolized cottonseed protein

[0050] The light seeds go through a wind-powered seed cleaning machine to remove impurities, sieve and remove the cotton husk after peeling, control the husk content in the kernel at 10% to 15%, and enter the softening process to soften. The softening temperature is 75°C, and the softening time is about 30 minutes. After softening, it is rolled. Embryo machine flaking, the thickness of the embryo sheet is required to be 0.35mm. After flaking, the embryo before immersion is called green embryo. In order to extract the fat in the embryo to the maximum extent, the green embryo needs to be dried to remove part of the water. , Change the distribution form of oil in the embryo. Then it is sent to the degreasing extractor for degreasing, and the moisture content of the embryo entering the degreasing extractor is required to be less than 8%, the temperature is 60°C, and the powder degree is less than 10%.

Abstract

The invention discloses a desolvation tempering method for plant protein containing single or mixed solvent, relates to a method for producing plant protein and aims at providing desolvation tempering method for plant protein containing single or mixed solvent, which is low in energy consumption, low protein degeneration rate and high in solvent removing rate. The desolvation tempering method for plant protein containing single or mixed solvent comprises the following steps of: A, pre-desolventizing the degreased or leached protein material by a dryer under the normal pressure; B, feeding the protein material which is pre-desolventized under the normal pressure to the dryer for being desolventized under reduced pressure; C, indirectly heating up the protein material which is desolventized the under reduced pressure by steam for being pre-desolventized under a high-vacuum state; D, directly ventilating steam to the pre-desolventized protein material under the high-vacuum state and indirectly heating up the protein material by the steam after being heated up by the steam; and E, humidifying the protein material, which is indirectly heated up by the steam, by hot air and cooling the protein material to remove water.

Description

technical field [0001] The invention relates to a method for producing vegetable protein, in particular to a method for removing and conditioning solvent in vegetable protein. Background technique [0002] my country is the country with the largest population in the world. The demand for protein in the food industry and animal husbandry industry is very large, and it cannot be self-sufficient. Every year, it imports more than 50 million tons of soybeans, produces more than 10 million tons of soybeans, and 4 million tons of cottonseed. In addition, my country's rapeseed and peanut production are also among the top in the world, as well as corn gluten. At present, according to analysis, the demand for self-produced vegetable protein in my country is at least 50%. [0003] Protein is the basic nutrient component of human body and animals. After entering the body, it will constitute all or most of the skeleton and body of the human body. Therefore, its biotransformation rate i...
