Starch gelatinization system

Abstract

The invention discloses a starch gelatinization system. The starch gelatinization system comprises a gelatinization heating cylinder, a stirring assembly and a shunting mechanism, the bottom of the gelatinization heating cylinder is connected with a heating base, the heating base is further connected with an air supply mechanism, and an end cover is detachably arranged at the top of the gelatinization heating cylinder; and a stirring assembly is rotationally arranged in the gelatinization heating cylinder and used for stirring starch in the gelatinization heating cylinder and scraping and separating starch attached to the inner wall of the gelatinization heating cylinder. According to the gelatinization heating cylinder, an annular partition plate is arranged in a heating cavity formed between a heating inner container and a heating cylinder body, the annular partition plate can be adjusted to ascend and descend through an adjusting screw rod, the heating area of the gelatinization heating cylinder is changed according to the gelatinization starch amount, and the effects of saving energy and reducing the processing cost are achieved.

Description

technical field [0001] The invention relates to the technical field of starch gelatinization processing equipment, in particular to a starch gelatinization system. Background technique [0002] Starch is insoluble in water at room temperature, but when the water temperature rises above 53°C, the physical properties of starch change significantly. Starch swells and splits at high temperature to form a uniform paste-like solution, which is called gelatinization of starch. Raw starch is heated in water until the micellar structure completely collapses, and starch molecules form single molecules, which are surrounded by water and become a solution state. Since the starch molecules are chain-like or even branch-like, they are involved with each other, resulting in the formation of a viscous pasty solution, which is called gelatinization. [0003] Starch gelatinization system is a kind of equipment for starch gelatinization processing. Currently, most of the fixed gelatinization ...

AI Technical Summary

Problems solved by technology

[0003] Starch gelatinization system is a kind of equipment for starch gelatinization processing. Currently, most of the fixed gelatinization heating tanks are used to heat starch through the compartment cavity of the tank body. The heating area is fixed, and the starch dosage cannot be adjusted according to the needs of gelatinization heating. The size of the area, and starch gelatinization is to produce a viscous paste solution on the inner wall of the heating tank. Traditional stirring measures cannot separate the external gelatinized starch from the convective flow, resulting in uneven heating of the starch and affecting the gelatinization effect of the starch.
