Description
Technical Field
[0001] The utility model relates to the technical field of kudzu powder drying, and more specifically, it relates to a kudzu powder drying device. Background Art
[0002] Kudzu powder is dark white in color and has a state like artificially ground small stones, with edges and corners as well as powder. It is very difficult to grind it into powder by hand. After slightly grinding it finer, there is a fine granular feeling. It has the effects of nourishing the face and skin and removing garbage in the body. The processing process of kudzu powder includes cleaning the root tuber, crushing and grinding into pulp, screening, washing, dehydration, drying and other processes. In the process of drying kudzu powder, a corresponding kudzu powder drying device is required.
[0003] Most of the existing kudzu powder drying equipment uses hot air flow to circulate inside the drying tank to dry the falling kudzu powder. Since the kudzu powder is wet and easy to form lumps, in order to ensure the uniformity of drying the kudzu powder, the lumped kudzu powder is usually dispersed by a stirring rod. Due to the wetness of the kudzu powder, when the stirring rod disperses the lumped kudzu powder, the kudzu powder will stick to the stirring rod. Since the stirring rods are all arranged inside the drying tank, it is not convenient to clean the stirring rods. In addition, the kudzu powder is dried during the falling process, and the contact time between the kudzu powder and the hot air flow is short, so the drying effect on the kudzu powder is poor. Summary of the Utility Model

Through the plurality of stirring rods 7, it is convenient to disperse the agglomerated kudzu powder on the sieve 3.
[0035] In summary, when the whole device is in use:
[0036] Add the kudzu root powder to be dried into the interior of the storage bin 28, then cover the lid of the storage bin 28 on the storage bin 28, and then open the first valve 30. The kudzu root powder inside the storage bin 28 falls onto the screen 3 inside the drying tank 1 through the connecting pipe 29. The kudzu root powder passes through the mesh holes of the screen 3 and falls into the interior of the cylinder 12. At the same time, drive the first gear 22 to rotate by the first motor 21. The first gear 22 drives the second gear 23, the rotating pipe 5, the rotating plate 6 and a plurality of stirring rods 7 to rotate. It is convenient to disperse the agglomerated kudzu root powder on the screen 3 through the plurality of stirring rods 7. The dispersed kudzu root powder passes through the mesh holes of the screen 3 and falls into the interior of the cylinder 12.
