Description

Technical Field

[0001] The utility model relates to the technical field of kudzu root powder processing equipment, in particular to a kudzu root powder drying device. Background Art

[0002] Pueraria root powder is often used as a traditional Chinese medicine because of its effects of relieving fever, relieving restlessness, promoting body fluid and quenching thirst.

[0003] Pueraria powder is made from kudzu root through a series of processing techniques, and its production process generally includes the following steps: picking kudzu root - cleaning - drying - cutting into strips and grinding - sieving - drying - cooling, wherein the drying process mainly functions to extend the shelf life of kudzu root powder. In the existing kudzu root powder production process, the kudzu root powder is dried with the aid of drying equipment.

[0004] After searching, a Chinese utility model patent with the authorization announcement date of CN221036511U and the authorization announcement date of May 28, 2024, and the patent name of "A device for uniform drying of kudzu root powder" was found. It discloses that by setting a stirring tank, a stirring rod in the stirring tank is driven by a motor to stir the kudzu root powder, so that the blocky kudzu root powder can be crushed to make the volume of the kudzu root powder more uniform, thereby saving drying time and making the kudzu root powder more uniform when drying. In the above scheme, the main problem is that the kudzu root powder raw material is stirred by the stirring device set. Since the kudzu root powder raw material itself has a certain humidity, when the stirring device is used to rotate and stir the original kudzu root powder, the kudzu root powder is very easy to adhere to the inner wall of the stirring tank and the stirring rod, and the kudzu root powder is easy to clump, which is not conducive to the subsequent uniform drying of the kudzu root powder. Summary of the invention

[0005] In view of the defects existing in the prior art, the purpose of the utility model is to provide a kudzu root powder drying device to solve the problem that the existing kudzu root powder drying equipment uses a stirring device to stir the original kudzu root powder in order to ensure the uniformity of the kudzu root powder, which causes the kudzu root powder to adhere and agglomerate easily.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The present application provides a kudzu root powder drying device, which includes a housing, a hopper, a drying pipe, a rotation driving assembly, a conveying assembly and a hot air blower. The hopper is arranged at the top end of the housing, and the bottom end of the hopper is communicated with the inner cavity of the drying pipe. The drying pipe is horizontally arranged in the inner cavity of the housing along the length direction of the housing, and the drying pipe is rotationally connected with the housing. The rotation driving assembly is connected with the drying pipe and is used for driving the drying pipe to rotate. A plurality of material dropping holes are arranged at intervals on the pipe wall of the drying pipe. The conveying assembly is installed at the bottom end of the housing, is arranged below the drying pipe, and is communicated with the inner cavity of the housing for receiving the powder falling in the inner cavity of the drying pipe. The hot air blower is communicated with the inner cavity of the housing through a provided hot air pipeline.

[0008] Furthermore, the kudzu root powder drying device further includes a plurality of hot air supply pipes. The plurality of hot air supply pipes are arranged at intervals along the length direction of the housing. One ends of the plurality of hot air supply pipes are communicated with the hot air blower, and the other ends of the plurality of hot air supply pipes are respectively connected with a corresponding plurality of the hot air pipelines.

[0009] Furthermore, an inclined guiding surface is formed at the inner wall position of the housing corresponding to the hot air pipeline. The hot air pipeline is fixedly installed on the inclined guiding surface, and the hot air pipeline is formed with a hot air inlet.

[0010] Furthermore, the conveying assembly includes a conveying pipe, a conveying screw and a screw driving motor. The conveying pipe is fixedly arranged at the bottom end of the housing, and the upper part of the conveying pipe is communicated with the inner cavity of the housing. The conveying screw is rotatably installed in the inner cavity of the conveying pipe. The screw driving motor is connected with one end of the conveying screw and is used for driving the conveying screw to rotate. An outlet is formed at the bottom of the other end of the conveying pipe relative to the screw driving motor.

[0011] Furthermore, the kudzu root powder drying device further includes a powder collection box, and the powder collection box is arranged below the outlet.

[0012] Furthermore, a heat insulation layer is arranged on the inner wall of the housing.

[0013] Furthermore, the rotation driving assembly includes a rotation motor and a rotation shaft. Two ends of the rotation shaft are respectively rotatably installed on the housing, the drying pipe is fixedly installed on the rotation shaft, and the rotation motor is connected with one end of the rotation shaft and is used for driving the rotation shaft to rotate.

[0014] The beneficial effects of the present utility model are as follows: The powdery kudzu root powder falls into the inner cavity of the drying pipe arranged horizontally and rotatably below through the hopper. When the kudzu root powder entering the inner cavity of the drying pipe rotates along with the drying pipe, the rotating kudzu root powder will rotate from the bottom end of the inner wall of the drying pipe to the top end and then fall freely. During this process, collisions and squeezes will occur between the kudzu root powders and between the kudzu root powder and the inner wall of the drying pipe, effectively avoiding caking between the kudzu root powders. And as the drying pipe rotates and with the continuous addition of kudzu root powder, the kudzu root powder at the feeding port of the drying pipe will gradually move towards the other end of the drying pipe. While rotating and moving in the inner cavity of the drying pipe, the kudzu root powder will fall downward through the material dropping holes opened on the pipe wall of the drying pipe and enter the conveying screw below (the arrangement of the material dropping holes can prevent the blocky kudzu root powder from discharging). At the same time, hot air provided by a hot air blower is filled in the inner cavity of the housing, and the hot air will flow from the inner cavity of the housing into the inner cavity of the drying pipe, and the hot air exchanges heat with the kudzu root powder to heat and dry it; the kudzu root powder after being heated and dried falls into the conveying screw and is conveyed forward, completing the drying and conveying process of the kudzu root powder.

The hot air duct 141 is communicated with the inner cavity of the housing 110. At the same time, in order to ensure the uniformity of the hot air entering the inner cavity of the housing 110, the other ends of the plurality of hot air ducts 141 are evenly arranged at intervals along the length direction of the housing 110. In this way, the hot air entering the inner cavity of the housing 110 can be evenly supplied along the length direction of the housing 110, which is more beneficial to the drying effect of the kudzu powder. Continue to refer to the attached Figure 1 and the attached Figure 3As shown, in addition, a plurality of hot air supply pipes 143 and a hot air duct 141 can be formed symmetrically on the front and rear opposite sides of the housing 110, so that the drying effect of kudzu starch is better. Additionally, referring to the appendix Figure 3 As shown, in order to slow down the heat loss in the inner cavity of the housing 110, a heat insulation layer 115 is formed on the inner wall of the housing 110.

[0026] Referring to the appendix Figure 1 As shown, in order to enable the hot air entering the inner cavity of the housing 110 to be discharged more effectively, a plurality of air discharge ports 113 are formed near the top of the front and rear side surfaces of the housing 110, and the plurality of air discharge ports 113 are arranged at equal intervals along the length direction of the housing 110.

[0027] Referring to the appendix Figure 3 As shown, an inclined guiding surface 117 is formed at the inner wall position of the housing 110 corresponding to the hot air duct 141, the hot air duct 141 is fixedly installed on the inclined guiding surface 117, and a hot air inlet 117a is formed at the port of the hot air duct 141 installed in the inner cavity of the housing 110.

[0028] Referring to the appendix Figure 1 to the appendix Figure 3 As shown, the conveying assembly is arranged at the bottom end surface of the housing 110, and its function is to receive the kudzu starch output from the drying pipe 120 and continue to convey it forward for discharging.

[0029] Specifically, the conveying assembly includes a conveying pipe 130, a conveying screw 133a, and a screw driving motor 133. The conveying pipe 130 is fixedly arranged at the bottom end of the housing 110, the upper part of the conveying pipe 130 is communicated with the inner cavity of the housing 110, the conveying screw 133a is rotatably installed in the inner cavity of the conveying pipe 130, the screw driving motor 133 is connected to one end of the conveying screw 133a for driving the conveying screw 133a to rotate, and a discharge port 135 is formed at the bottom of the other end of the conveying pipe 130 relative to the screw driving motor 133. Additionally, referring to the appendix Figure 1 As shown, a powder collection box 150 for receiving kudzu starch is further provided below the discharge port 135 on the conveying pipe 130.

[0030] Referring to the appendix Figure 2 As shown, in order to better understand the kudzu starch drying device in this embodiment, the following briefly describes its working principle:

[0031] The kudzu root powder to be dried is added to the silo. The powdery kudzu root powder falls into the inner cavity of the drying pipe 120 arranged horizontally and rotatably below through the hopper 111. When the kudzu root powder entering the inner cavity of the drying pipe 120 rotates along with the drying pipe 120, the rotating kudzu root powder will rotate from the bottom end of the inner wall of the drying pipe 120 to the top end of the drying pipe 120 and then fall freely. During this process, collisions and squeezes will occur between the kudzu root powders and between the kudzu root powder and the inner wall of the drying pipe 120, effectively avoiding caking between the kudzu root powders. And with the rotation of the drying pipe 120 and the continuous addition of the kudzu root powder, the kudzu root powder at the feed inlet of the drying pipe 120 will gradually move towards the other end of the drying pipe 120. While the kudzu root powder rotates and moves in the inner cavity of the drying pipe 120, the kudzu root powder will fall downward through the material dropping holes 125 opened on the pipe wall of the drying pipe 120 and enter the conveying screw 133a below (the setting of the material dropping holes 125 can prevent the agglomerated kudzu root powder from discharging). At the same time, hot air provided by the hot air blower 140 is filled in the inner cavity of the housing 110, and the hot air will flow from the inner cavity of the housing 110 into the inner cavity of the drying pipe 120. The hot air exchanges heat with the kudzu root powder and heats and dries it. The kudzu root powder after heating and drying falls into the conveying screw 133a and is conveyed forward, completing the drying and conveying process of the kudzu root powder.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model is also intended to include these changes and modifications.
