Description

Technical Field

[0001] The utility model relates to the technical field of starch processing, in particular to a dehydration device for producing high-purity wheat starch. Background Art

[0002] Wheat is the name of a plant in the wheat family. It is a monocotyledonous plant and a grass plant widely grown around the world. The caryopsis of wheat is one of the staple foods of humans. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods. After fermentation, it can be made into beer, alcohol, white wine, or biofuel.

[0003] Existing starch processing technology often uses a dehydration device for producing wheat starch, such as the one disclosed in announcement number CN217154896U. The device places the starch to be dehydrated on a filter cloth layer of a first belt conveyor. When the starch moves under the extrusion plate, the piston rods of the two synchronous cylinders extend at the same time to squeeze the starch and squeeze out the water in the starch. The extruded starch falls onto a second belt conveyor, and the electric heating element heats and dries the starch inside the drying box. The extruded starch forms powder blocks, which are less heated when entering the drying box, and some moisture will remain, affecting the dehydration quality of the starch. Utility Model Content

[0029] The function principle of the device can be described by the following operation mode:

[0030] Starch is placed in the main body 1, and liquid is injected into the heating chamber 2 from the water inlet 3 to heat it. The first drive motor 6 is turned on to control the central shaft 12 and the support turntable 11 to rotate clockwise. The first drive bevel gear 14 rotates to drive the transmission bevel gear 15 to rotate, thereby driving the second drive bevel gear 17 to rotate counterclockwise, and then driving the driven shaft 13 to rotate counterclockwise.
