Method for deep processing and treating starch for foods

Abstract

The invention relates to a method for deep processing and treating starch for foods. A food processing device is used by the method. The food processing device comprises a discharging frame, a mincingunit, a feeding opening, and a discharging unit, wherein the mincing unit is arranged at the upper end of a discharging frame; the feeding opening is formed in the upper end of the mincing unit; andthe discharging unit is arranged on the inner wall at the lower end of the discharging frame. According to the method for deep processing and treating starch for foods disclosed by the invention, through the two-stage crushing and milling method, sweet potatoes are completely crushed; through triangular material waiting regions formed between a cooperation block and smashing strips, the problem that an inlet of a milling mechanism is blocked by sweet potato blocks which are not completely crushed, and the discharging of the sweet potato blocks is influenced is solved; and by a method of performing discharging, performing precipitation, performing dividing and performing precipitation again, most of a starch solution is reserved, so that the problem that a part of starch is discharged alongwith moisture, and the yield of the collected starch is reduced, is solved.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a food starch deep processing method. Background technique [0002] Starch is a high molecular weight carbohydrate, a polysaccharide composed of a single type of sugar unit. The basic unit of starch is glucose, and the covalent polymer formed by the dehydration of glucose and linked together through glycosidic bonds is starch molecule. Starch is a polyglucose. [0003] Sweet potato starch is also called sweet potato starch, sweet potato starch, sweet potato starch, yam starch, mountain powder, etc. It is better to buy coarse grains at home. Sweet potato starch, like corn starch, will become viscous when heated in water, while sweet potato powder has a higher viscosity than corn starch. Therefore, sweet potato powder is less used when thickening Chinese dishes, because the viscosity is difficult to control. It is widely used in the production of Chinese dim sum, such a...

AI Technical Summary

Problems solved by technology

[0004]Sweet potato starch often has the following problems in the production process: 1. During the process of crushing sweet potatoes, some sweet potato pieces are not completely crushed, so that the sweet potato pieces cannot be crushed. It enters the milling mechanism and is processed, and accumulates at the entrance of the milling mechanism, thereby hindering the cutting of sweet potatoes; 2. Due to the lack of fluidity of starch, it is necessary to drive the starch to be discharged through the flow of water, so in the final collection process Due to too much water, the container cannot carry the load, resulting in part of the starch being discharged with the water, which reduces the yield of the collected starch.
