Reaction kettle protection device for processing modified starch

Abstract

The invention discloses a reaction kettle protection device for processing modified starch, and belongs to the technical field of modified starch processing, and the reaction kettle protection devicecomprises a reaction kettle body, the reaction kettle body is arranged in a protection shell, and a guide plate is also welded between the outer surface of the reaction kettle body and the inner sidewall of the protection shell; a temperature sensor and a pressure sensor are used for sensing the temperature and the pressure in the reaction kettle body; sensed real-time data is converted by a signal conversion module and then sent to a single-chip microcomputer; the single-chip microcomputer calls standard temperature and pressure upper limit values stored in a storage module and sends the twokinds of data to a comparison module; when the real-time temperature and pressure data exceeds the standard upper limit values, a water pump and a pressure release valve are started, so that coolingwater enters a cooling water pipe to cool the reaction kettle body, the pressure release valve is used for releasing pressure, the protection performance is good, and the problem that safety accidentsare easily caused by loosening of a remote operator is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of modified starch processing, and in particular relates to a reactor protection device for modified starch processing. Background technique [0002] After the raw starch is processed by a certain method, its original physical or chemical properties are changed to varying degrees. On the basis of the inherent properties of the native starch, in order to improve the performance of the starch and expand its application range, physical, chemical or enzyme Introduce new functional groups on starch molecules or change the size of starch molecules and the properties of starch granules, thereby changing the natural characteristics of starch and making it more suitable for certain application requirements. This kind of starch that has undergone secondary processing and changed properties is collectively referred to as For modified starch. [0003] In the original modified starch processing process, the operator rem...

AI Technical Summary

Problems solved by technology

[0003] In the original modified starch processing process, the operator remotely observes the internal pressure and temperature of the reactor through the computer. When the temperature and pressure are too high, the pressure is released and cooled remotely. When the operator is slack, the pressure and temperature cannot be adjusted in time. control, which can easily lead to safety accidents
