Apparatus used for uniformly mixing trace reagent and macro material in production of modified starch

Abstract

The invention discloses an apparatus used for uniformly mixing a trace reagent and a macro material in the production of modified starch. The apparatus comprises a bottom base plate and a mixing cylinder, wherein one end, close to a hinge rod frame, of the bottom wall of the mixing cylinder is provided with a material discharge channel, a stirring round pipe coaxial with the mixing cylinder is arranged inside the mixing cylinder, the side wall, positioned inside the mixing cylinder, of the stirring round pipe is provided with a plurality of mixing pushing pipes, the side walls of the mixing pushing pipes are provided with a plurality of reagent dispersing holes, the outer side of the stirring round pipe is fixedly connected to a plurality of pushing rod frames, the pushing rod frames are provided with pressing rollers rotatably connected to the pushing rod frames, an airbag sleeve is arranged close to the inner wall of the mixing cylinder, the stirring round pipe bears against the inner side surface of the airbag sleeve, and the side wall of the mixing cylinder is provided with an inflation port. According to the present invention, the apparatus has characteristics of simple structure, convenient discharge of the mixed material, complete mixing, relatively low energy consumption, continuous mixing, continuous production, high production efficiency and strong practicability.

Description

technical field [0001] The invention relates to the technical field of modified starch production, in particular to a device for uniformly mixing trace reagents and macroscopic materials for modified starch production. Background technique [0002] Modified starch is a new material technology, that is, after the original starch is processed by a certain method, its original physical or chemical properties are changed to varying degrees. On the basis of the inherent characteristics of natural starch, in order to improve the performance of starch and expand its application range, physical, chemical or enzymatic treatment is used to 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 (such as: gelatinization temperature, thermal viscosity and its stability, freeze-thaw stability, gel force, film-forming property, transparency, etc.), making it mor...

Problems solved by technology

In the existing dry modified starch production process, liquid reagents and macro-materials are mixed. However, due to the small amount of liquid reagents added in this method, there will be too much local mixing of the two materials that react with each other. The problem of less mixing of most materials, that is, uneven mixing, leads to uneven product reaction and unstable performance
