[0030] The kudzu root powder concentration mechanism 1 comprises a material storage box 101, the top of the material storage box 101 is an open mouth, the back of the material storage box 101 is provided with a material inlet, the bottom of the material storage box 101 is fixedly connected with a material discharge part 102, the material discharge part 102 is conical, and the bottom axis of the material discharge part 102 is provided with a material discharge port;

[0031] A transmission roller 103 is symmetrically installed inside the material box 101 and driven by a motor. A synchronous belt 104 is transmitted on the outer surface of the transmission roller 103. The width of the synchronous belt 104 is equal to the width of the inner wall of the material box 101, and the synchronous belts 104 on both sides are close to each other.

[0032] The circulating conveying device 3 includes a vertical cylinder 301, a feeding auger 302 is installed inside the vertical cylinder 301, and a transmission motor 303 is installed on the top of the vertical cylinder 301, and the transmission motor 303 drives the feeding auger 302;

[0033] A feed pipe 304 is installed at the bottom of the side of the vertical cylinder 301 and is connected to the discharge port at the bottom of the lower material part 102 . A discharge pipe 305 is installed above the side of the vertical cylinder 301 and is connected to the feed port on the material holding box 101 .

[0034] Through the above technical solution, a transmission roller 103 is arranged inside the material box 101 to drive the synchronous belt 104 to rotate relatively, break up the agglomerated kudzu root powder, and the kudzu root powder at the bottom of the material box 101 is conveyed to the top of the synchronous belt 104 by the feeding auger 302, so as to achieve repeated rolling and avoid the agglomeration of the kudzu root powder.

[0035] By repeatedly conveying the kudzu root powder to the top of the synchronous belt 104 by the feeding auger 302, in addition to effectively preventing the kudzu root powder from clumping, the repeatedly conveyed kudzu root powder will turn over due to the repeated conveyance, thereby increasing the contact area with the hot air blown out by the drying device 2, thereby achieving the effect of improving the drying efficiency.

[0036] Specifically, the synchronous belt 104 is arranged obliquely, and the synchronous belt 104 arranged obliquely on both sides is in an inverted figure eight shape.

[0037] Through the above technical solution, the synchronous belt 104 is tilted so that the kudzu root powder can fall into the inside of the discharge part 102 under the action of gravity so as to be further transported, and the inverted figure eight shape can make the kudzu root powder fall into the feed pipe 304 more easily.

[0038] Specifically, the feed port opened on the material holding box 101 is located above the synchronous belt 104 , and the feed port is located at the intersection between two synchronous belts 104 .

[0039] Through the above technical solution, the position of the feed port is set so that the repeatedly conveyed kudzu root powder can fall onto the surface of the synchronous belt 104 more concentratedly, and then be crushed under the relative power of the synchronous belts 104 on both sides, thereby avoiding agglomeration.

[0043] Through the above technical scheme, the diameter of the wing of the feeding auger 302 is set to avoid the existence of a gap between the outer surface of the feeding auger 302 and the inner wall of the vertical cylinder 301. The existing gap will affect the feeding efficiency of the feeding auger 302, and the height of the discharge pipe 305 is set so that during the feeding process of the feeding auger 302, the kudzu root powder can enter the interior of the material containing box 101 through the discharge pipe 305.

[0045] Through the above technical solution, the protective box 201 is mainly used for protection and heat insulation, and the heating tube 203 is used to heat the air. The heated air is sent to the interior of the material box 101 through the air blown by the air supply fan 204 to dry the kudzu powder.

[0046] Specifically, there are multiple air supply fans 204 , and the multiple air supply fans 204 are evenly distributed on the top of the protection box 201 .

[0047] Through the above technical solution, the purpose of providing multiple air supply fans 204 is to increase the blowing area of ​​hot air, thereby achieving better drying effect and drying efficiency.

[0048] When in use, a transmission roller 103 is arranged inside the material box 101 to drive the synchronous belt 104 to rotate relatively, so as to break up the agglomerated kudzu root powder, and the kudzu root powder at the bottom of the material box 101 is conveyed to the top of the synchronous belt 104 by the feeding auger 302, so as to achieve repeated rolling and prevent the kudzu root powder from agglomerating.

[0049] By repeatedly conveying the kudzu root powder to the top of the synchronous belt 104 by the feeding auger 302, in addition to effectively preventing the kudzu root powder from clumping, the repeatedly conveyed kudzu root powder will turn over due to the repeated conveyance, thereby increasing the contact area with the hot air blown out by the drying device 2, thereby achieving the effect of improving the drying efficiency.
