Description

Technical Field

[0001] The utility model belongs to the technical field of mixers, and more specifically, particularly relates to a high-speed mixer for producing modified starch. Background Art

[0002] Modified starch is a modified starch. On the basis of the inherent properties of natural starch, in order to improve the performance of starch and expand its application range, new functional groups are introduced into starch molecules or the size of starch molecules and the properties of starch particles are changed by physical, chemical or enzymatic treatment, thereby changing the natural properties of starch (such as gelatinization temperature, thermal viscosity and its stability, freeze-thaw stability, gel strength, film-forming property, transparency, etc.) to make it more suitable for certain application requirements. This kind of starch that has undergone secondary processing and changed its properties is collectively called modified starch.

[0003] The purpose of starch deformation is to meet the requirements of various industrial applications, such as: high temperature technology (canning sterilization) requires starch to have good high temperature viscosity stability, frozen food requires starch to have good freeze-thaw stability, jelly food requires good transparency and good film-forming properties, etc.; secondly, to open up new uses for starch and expand its application range. For example: using starch in textiles; hydroxyethyl starch and hydroxypropyl starch instead of plasma; highly cross-linked starch instead of talcum powder for surgical gloves, etc.

[0004] In the production process of modified starch by hot rolling, mixing, drying, crushing, screening and other processes are usually required. During mixing, chemicals and water need to be added to the original starch in a mixing barrel and stirred. The existing technology often uses chemicals and aqueous solutions to be added through the feed port or the liquid addition port. To ensure safety, the above operations are usually carried out after shutdown, and a lot of stirring is required after adding liquid, and it is not easy to ensure uniform mixing.
