Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

1 to 3, a circulating drying and cooling device for Radix Rehmanniae Preparata comprises a sand pot 1, a feeding hopper 2 is connected to the top of the sand pot 1, a cold air duct 3 and a hot air duct 4 are fixedly penetrated through the side walls of the sand pot 1, the cold air duct 3 and the hot air duct 4 are respectively connected to a cold air blower 5 and a hot air blower 6 at one end outside the sand pot 1, the cold air blower 5 and the hot air blower 6 are both fixedly connected to the outer wall of the sand pot 1, a water storage tank 24 is fixedly connected to the front wall of the sand pot 1, a water pump 25 whose water outlet end is fixedly penetrated into the sand pot 1 is fixedly connected to the side wall of the water storage tank 24, a temperature sensor 22 is fixedly connected to the inner wall of the sand pot 1, and a controller 14 is fixedly connected to the outer wall of the sand pot 1. When in use, the Radix Rehmanniae Preparata to be dried and cooled is poured into the sand pot 1 through the feeding hopper 2, and then the water pump 25 is turned on to make the storage tank 24 cool. The water in the water tank 24 flows into the sand pot 1 to clean the Rehmannia root in the sand pot 1, and then when drying the Rehmannia root, the hot air blower 6 is turned on and the cold air blower 5 is turned off, and the hot air is transported to the sand pot 1 through the hot air pipe 4 for drying. After the drying is completed, the hot air blower 6 is turned off and the cold air blower 5 is turned on, and the cold air is transported to the sand pot 1 through the cold air pipe 3 to cool the Rehmannia root. During use, the temperature and time of drying the Rehmannia root in the sand pot can be controlled by the temperature sensor 22 and the operation controller 14. The user only needs to turn on the designated fan to achieve drying and cooling of the Rehmannia root. When drying, the controller 14 and the temperature sensor 22 can be used to cooperate to make the temperature and drying time in the sand pot 1 60°C-70°C and two hours respectively. The operation is simple and convenient.

A rotating shaft 7 is movably provided through the front wall of the sand pot 1, and a stirring rod 8 is fixedly connected to the side wall of the rotating shaft 7. A reciprocating stirring mechanism is provided at one end of the rotating shaft 7 located outside the sand pot 1, and the reciprocating stirring mechanism includes a motor 11 fixedly connected to the outer wall of the sand pot 1, and a half gear 10 is fixedly connected to the end of the output shaft of the motor 11. A rack 9 is meshed with the lower side wall of the half gear 10, and a door-type plate 12 located at the periphery of the half gear 10 is fixedly connected to the upper side wall of the rack 9. A tooth groove is provided on the inner top wall of the door-type plate 12, and a gear 19 fixedly connected to the end of the rotating shaft 7 is meshed on the side of the rack 9 away from the half gear 10. The outer wall of the rack 9 is symmetrically movably sleeved with two limit blocks 13 fixedly connected to the front wall of the sand pot 1. When the Rehmannia glutinosa is washed, dried or cooled, the start The motor 11 drives the half gear 10 to rotate clockwise. When the half gear 10 and the rack 9 are meshed, the rack 9 moves to the right. When the half gear 10 is disengaged from the tooth grooves on the rack 9 and the door plate 12, the rack 9 will be driven to move to the left. Therefore, under the continuous rotation of the half gear 10, the rack 9 can be reciprocated left and right. Then, the gear 19 meshing therewith can be used to realize the reciprocating swing of the stirring rod 8, so as to stir the Rehmannia glutinosa back and forth in the sand pot 1, increase the contact area of the hot air or cold air of the Rehmannia glutinosa in the sand pot 1, so as to fully dry and cool the Rehmannia glutinosa in the sand pot 1, so as to reduce the drying or cooling time, thereby improving the drying or cooling effect of the Rehmannia glutinosa, greatly improving its working efficiency, and accelerating the pharmaceutical preparation progress.

The lower wall of the sealing plate 18 is fixedly connected to a sewage pipe 23 connected to the inside of the sand pot 1. An electronic valve is provided in the sewage pipe 23. After the Rehmannia glutinosa is just cleaned, the electronic valve is opened to discharge the sewage through the sewage pipe 23. After the Rehmannia glutinosa is dried and cooled, the motor 20 is turned on when it is necessary to discharge the material, so that the end of its output shaft drives the sealing plate 18 to rotate clockwise to open the discharge port, so that the Rehmannia glutinosa that has been dried and cooled can be smoothly taken out, and the operation is simple.

The bottom of the sand pot 1 is fixedly connected to a base 16 through two legs 15, and a collecting box 17 is movably inserted into the upper side wall of the base 16. The upper side wall of the collecting box 17 is open, and the Rehmannia glutinosa discharged from the discharge port after drying and cooling is completed can be collected. The upper side wall of the base 16 is provided with a positioning groove matching the collecting box 17, so that the collecting box 17 can be limited while collecting the Rehmannia glutinosa to prevent shaking.

Furthermore, a plurality of protrusions 21 are fixedly connected to the inner wall of the sand pot 1, so that when the Rehmannia root moved by the stirring rod 8 contacts the protrusions 21, the Rehmannia root can be further turned over, thereby further improving the drying and cooling effect of the Rehmannia root.
