Embodiment Construction

[0041] In order to illustrate the technical features of the solution more clearly, the solution will be described below through specific implementation modes.

[0042] see figure 1 , a process method for extracting pea albumin in water, the method comprises the following steps:

[0043] Step S1: preparing waste water, adjusting its temperature, pouring the waste water into centrifuge 1-2, under the action of centrifuge 1-2, large particles in the waste water are precipitated, and finally the first clear liquid is obtained;

[0044] Step S2: the first clear liquid is concentrated through the first concentration membrane to form two substances, the first concentrated liquid and the first clear water, the first concentrated liquid is kept for use, and the first clear water passes through the reverse osmosis membrane for reverse osmosis to obtain purified water;

[0045] Step S3: increasing the air pressure at the upper end of the first concentration membrane through the pressure...

Abstract

The invention provides a process method and device for extracting pea albumin from water. The process method comprises the following steps: the waste water is prepared and poured into a centrifuge, and finally first clear liquid is obtained; the first clear liquid is concentrated through a first concentration membrane to form two substances of first concentrated liquid and first clear water; saccharides in the first concentrated liquid are separated out through an ultrafiltration membrane, and second clear liquid and interception liquid are formed; then the interception liquid is concentratedthrough a second concentration membrane to form second concentrated liquid and second clear water; a pressure circulation assembly simultaneously further changes the air pressure intensity of the bottom of a reverse osmosis membrane, and the air pressure intensity of the bottom end of the second concentration membrane; and the second concentrated liquid is subjected to compatibility drying to obtain pea protein powder. According to the process method and device for extracting the pea albumin from the water, the technical problem of how to extract pea protein from the waste water is solved, water resources are saved, and the added value of water resource utilization is increased.

Description

technical field [0001] The invention belongs to the field of food industry production, and in particular relates to a method for extracting pea albumin from process water for producing protein from peas. Background technique [0002] Peas belong to legumes. Peas are rich in various nutrients needed by the human body, especially high-quality protein. And legumes do not contain cholesterol, which is better than animal protein. Pea protein powder is a high-quality protein separated and extracted from pea using advanced technology and low-temperature and low-pressure technology. Pea protein contains 18 kinds of amino acids necessary for the human body and is a complete protein. Peas→cleaning→soaking→refining→pulp residue separation→centrifugation to remove starch→acid precipitation→centrifugation→sediment alkali dissolution→spray drying→finished product. Soak the peas that have been removed of impurities in water for 12-24 hours, then rinse them with clean water, and then grin...
