A crushing mechanism for the production of modified rice starch

Abstract

The invention provides a crushing mechanism for producing modified rice starch, comprising a stirring pond, a heating tank, a filter tank, a lifter and a crusher; raw material is conveyed into the stirring pond for stirring, is then pumped into the heating tank for reacting and cooled via a condenser, is fed into the filter tank that carries out moisture filtration removal in the same time and is finally lifted by the lifter into the crusher; the crushing mechanism is simple in structure and reasonable in design, the stirring pond is arranged underground, material conveying is facilitated, manual cost is reduced, the raw material is cooled while conveyed for moisture filtration, the technological process is simplified, the filter tank and a third connecting pipe are obliquely arranged, the raw material is never easily stacked to block the pipe, a crusher spindle is positioned through a spindle positioner, the spindle is clamped through positioning mechanisms that are crisscross arranged, axial derivation of the spindle is prevented, a slider and a slide may cooperate to provide certain support for the spindle, and sealing blocks can be provided to prevent dirt from entering the crusher from the spindle and prevent the modified starch from being polluted.

Description

technical field [0001] The invention relates to the field of modified rice starch production, in particular to a crushing mechanism for modified rice starch production. Background technique [0002] Modified rice starch is a modified starch. It has been applied in many fields such as textile, paper making, food, feed, casting, medicine, construction, petroleum, etc. Including oxidized starch, acid-modified rice starch, starch ester, starch ether, cross-linked starch, cationic starch, grafted starch, cyclodextrin, white dextrin, pregelatinized starch (pregelatinized starch), dialdehyde starch, etc. Wait. [0003] Modified rice starch refers to the use of physical, chemical or enzymatic treatment to introduce new functional groups on starch molecules or change the size of starch molecules and the properties of starch granules in order to improve the performance of starch and expand its application range, thereby changing the natural characteristics of starch ( Such as: gela...

AI Technical Summary

Problems solved by technology

[0004] In the production of modified rice starch, the existing raw materials need to be crushed, and the commonly used crushing mechanisms and processes have the following disadvantages: 1. The existing mixing pool is set above the ground surface, which leads to certain difficulties in feeding and increases the labor cost. Cost, or the need to purchase lifting equipment, which increases the cost of equipment purchase; 2. The condensation and cooling links are relatively independent, which increases the complexity of the process; 3. The stability of the main shaft of the pulverizer is insufficient, which leads to poor crushing effect; 4. The main shaft and Insufficient sealing between the pulverizers, causing oil and other dirt to easily enter the pulverizer and contaminate the product
