Description

Technical Field

[0001] This utility model relates to the field of modified starch processing technology, specifically to a reaction vessel for modified starch processing. Background Technology

[0002] Modified starch is starch that has undergone physical, chemical, or enzymatic treatment, altering its original structure and properties to impart new characteristics, thus enabling its wider application in various industries and food processing. Compared to natural starch, modified starch typically exhibits significant differences in viscosity, solubility, and stability. In the production of modified starch, a reaction vessel is used to mix starch with chemical agents (such as acids, oxidizing agents, or etherifying agents), and the mixture is heated and stirred to ensure a uniform reaction. The required high temperature is provided by a heating system (such as steam heating or electric heating), causing the starch to undergo physical or chemical modification.

[0003] For example, a high-efficiency reaction vessel for processing modified starch, disclosed in CN212790992U, includes a vessel body. A fixed plate is fixedly connected to the inner wall of the vessel body, and filter holes are formed on the surface of the fixed plate. A motor base is fixedly connected to the upper surface of the vessel body, and a motor is mounted on the surface of the motor base. The output end of the motor is movably connected to a transmission rod via a coupling. Through the arrangement of spiral blades, a fixed rod, and a brush, during use, turning on the motor switch drives the spiral blades to rotate, causing the starch and additive liquid to react evenly. When acidic starch residue adheres to the inner wall of the vessel, the rotating brush removes the residue, allowing it to be stirred again with the starch. This avoids the hassle of manually cleaning the inner wall of the vessel, allowing for simultaneous cleaning and stirring, thus improving efficiency.

[0004] The aforementioned patent proposes that the rotating brush can remove starch residue, allowing the acidic starch residue to be stirred with the starch again, thus avoiding the hassle of manually cleaning the inner wall of the reactor. However, in actual use, long-term use of a brush to clean the inner wall may cause damage or scratches to the inner wall of the reactor, especially in high temperature or high acid environment, repeated friction may cause the coating on the inner wall of the reactor to peel off or corrode.
