Problems solved by technology

[0002] Peanut is an important oil crop in my country, with an annual output of about 12 million tons, most of which are used to extract edible oil, and the protein content of the cake produced after oil extraction is about 40%, which is currently widely used as feed and fertilizer. When the intake is far below the national nutritional standard, it is a great waste of nutritional resources
According to the review of relevant materials, it was once proposed that peanut cakes should be crushed directly with a grinder to obtain peanut protein powder. The protein content in it has not changed, and there are no sanitation measures for sterilization and odor removal.

Embodiment

[0011] Example: The peanut cake is crushed into a powder with the pulverizer 1, and then soaked in the soaking tank 2 with an aqueous solution. After the powder absorbs water to reach saturation, it enters the fine mill 3 for fine grinding, and the finely ground solution is processed into a slurry with a separator 4. Separation, the separated solution enters the acidification tank 5 for acidification, the acidity is controlled below PH6.8, the acidified solution enters the dehydration separator 6 to remove part of the water, and the dehydrated solution enters the high temperature sterilizer 7 for 115°C- High-temperature sterilization at 135°C, the sterilized solution enters the deodorizer 8 to remove peculiar smell, and the deodorized solution enters the vacuum concentrator 9 to depressurize, lower the boiling point of the solution to evaporate the water quickly, and the concentrated solution enters the homogeneous The machine 10 is homogenized, and the homogenized solution is ...

Abstract

The invention relates to the technology of extracting edible protein from the peanut tablet. The main processing procedures go as follows: pulverizing, dipping, fine grinding, separating, acidifying, dehydrating, sterilizing, deodorizing, concentrating, homogenizing, pressurizing, spray-drying, cooling, weighing and packaging.

Description

technical field [0001] The invention relates to a process for extracting plant protein, in particular to a process for extracting edible protein from peanut cake. Background technique [0002] Peanut is an important oil crop in my country, with an annual output of about 12 million tons, most of which are used to extract edible oil, and the protein content of the cake produced after oil extraction is about 40%, which is currently widely used as feed and fertilizer. When the intake is far below the national nutritional standard, it is a great waste of nutritional resources. According to relevant information, it has been proposed that peanut cakes can be directly pulverized with a pulverizer to obtain peanut protein powder, in which the protein content does not change, and there are no sanitation measures for sterilization and deodorization. Contents of the invention [0003] The purpose of the present invention is to take...
