Abstract
Description
Technical Field
[0001] This utility model belongs to the field of modified starch processing technology, and in particular relates to a reaction vessel for the preparation of modified starch. Background Technology
[0002] To improve starch properties and expand its applications, starch is treated using physical, chemical, or enzymatic methods. This introduces new functional groups into the starch molecules or alters the size of the starch molecules and the properties of the starch granules, thereby changing the natural characteristics of starch (such as gelatinization temperature, thermal viscosity and its stability, freeze-thaw stability, gelling power, film-forming properties, and transparency) to better suit the requirements of specific applications. Starch that has undergone secondary processing and had its properties altered is collectively called modified starch.
[0003] In the prior art, the reaction vessel for the preparation of modified starch is generally simple in structure and does not have an internal cleaning device. When the modified starch is processed inside the vessel, residue is easily left, making it inconvenient to clean the inner wall of the vessel and affecting its later use. Therefore, a reaction vessel for the preparation of modified starch is proposed to solve the above problems. Utility Model Content

A heating plate with an annular structure is installed on the inner surface of the vessel body, facilitating temperature control within the vessel body, accelerating the reaction time during modified starch preparation, and improving the efficiency of the device. The magnetic suction plate, also an annular structure, is slidably mounted on the outer surface of the vessel body.

This allows the movable scraper to clean the inner wall of the heating plate, preventing modified starch residue and facilitating cleaning and subsequent use of the device.
[0007] Furthermore, the movable scraper has an annular plate structure, and the movable scraper is magnetically attracted to the magnetic plate. Two guide holes are opened on the upper surface of the movable scraper, and two guide rods are installed on the bottom surface inside the tank. The two guide rods are made of non-metallic material.

[0009] Furthermore, one end of each of the two lead screws passes through the upper surface of the two bearing plates, and the output ends of the two drive motors are fixedly connected to one end of each of the two lead screws.
[0010] Furthermore, a top cover is movably installed on the upper surface of the tank, a rotating motor is installed on the upper surface of the top cover, a controller is installed on the front side of the rotating motor, and a feed inlet is installed on one side of the rotating motor.
[0011] Furthermore, the lower end of the feed inlet is connected to the inside of the tank, a rotating shaft is installed at the output end of the rotating motor, the lower end of the rotating shaft extends into the inside of the tank, and several stirring blades are welded to the circumferential side of the rotating shaft.

[0013] Furthermore, the controller is electrically connected to the heating plate, the drive motor, and the rotation motor, respectively.
[0014] This utility model has the following beneficial effects:
[0015] This invention utilizes a screw, magnetic plate, and drive motor structure to facilitate the movement of the magnetic plate up and down, thereby moving the scraper inside the tank that is attracted to the magnetic plate. This allows the scraper to clean the inner wall of the heating plate, preventing the residue of modified starch and facilitating the cleaning and subsequent use of the device.
