Description

Technical Field

[0001] The invention relates to the technical field of starch drying devices, and in particular to a modified starch drying device for food. 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] Modified starch requires drying during processing. Drying is the process of heating and drying the raw materials mixed with the solvent to remove the moisture from the product after the reaction. To improve the drying efficiency, a roller is usually used. However, some starch will clump during the drying process. The clumped starch is mixed with the non-clumped starch. The clumped starch will block the heat, reducing the heating area of ​​the non-clumped starch and affecting the drying efficiency. Summary of the invention

[0034] As shown in the accompanying drawings, a modified starch drying device for food comprises a frame 1, a drying cylinder and a driving assembly;

[0035] The drying cylinder is rotatably arranged on the frame 1, and the driving assembly is installed on the frame 1 to drive the drying cylinder to rotate;

[0037] In the above scheme, the drying cylinder is composed of an inner cylinder and an outer cylinder, and the inner cylinder is used to place the modified starch to be dried. During the rotational drying process of the drying cylinder, the powdered modified starch in the inner cylinder is dried and enters the outer cylinder through the sieve holes on the inner cylinder, while the agglomerated modified starch remains in the inner cylinder, which can effectively improve the drying efficiency.

[0038] As another embodiment of the present invention, the inner cylinder includes a fixing frame 8 and a screening net 9, the fixing frame 8 is cylindrical, the screening net 9 is wound and installed on the fixing frame 8, and the sieve holes are arranged on the screening net 9.
