Processing method of soya flour

Abstract

The invention relates to a processing method of soya flour, and belongs to the technical field of preparation of products. The processing method of the soya flour comprises the following steps: machine selecting, color sorting, cryogenic grinding, autoclaving, drying and packaging. The processing method of the soya flour has the advantage that the color, aroma and taste of the soya flour and the characters of active substances are kept fixed.

Description

technical field

[0001] The invention relates to a processing method of bean flour, which belongs to the technical field of product preparation. Background technique

[0002] According to the applicant's understanding, the existing soybean powder processing has the following problems:

[0003] 1. The existing beans are tough at room temperature, difficult to crush, and cannot maintain the color, aroma, and texture of the product.

[0004] The taste and the nature of the active substance remain unchanged;

[0005] 2. Soy flour made from existing beans has poor fluidity and poor particle size distribution.

[0006] Ensure that the product is fine in detail;

[0007] 3. The deterioration phenomenon caused by heat, oxidation, etc. when the existing beans are crushed at room temperature;

[0008] 4. Odor escape, dust explosion, noise, etc. will occur when the existing beans are crushed;

[0009] 5. In the sterilization processing of existing beans, there are deterioration phe...

Examples

Embodiment

[0032] The processing method of the bean flour of the present embodiment may further comprise the steps:

[0033] (1) Machine selection: According to the particle size requirements of the product, select the screen of the corresponding specification to screen the beans, and at the same time perform magnetic separation to remove metal objects, powder and weeds;

[0034] (2) Color sorting: remove the heterochromatic particles left by the previous process;

[0035] (3) Frozen crushing: Put the beans separated from rice and rough into a freezing crushing device for freezing and crushing. The refrigerant is liquid nitrogen, and the freezing temperature is controlled at -100°C, and the beans are crushed into soybean powder;

[0036] The freezing and crushing device is generally composed of a refrigerant supply device (liquid nitrogen tank), a storage pre-cooling cylinder, a raw material freezer, a screw propeller, a low-temperature pulverizer, a product collector (cyclone separator)...
