[0020] In the structure of the dryer main body 1 of the present utility model, a drying chamber 102 is provided inside the dryer main body 1. A hot air drying device 6 communicating with the drying chamber 102 is provided at the top of the dryer main body 1. The hot air drying device 6 inputs hot air from top to bottom into the drying chamber 102 through the air outlet pipe 605. The drying tray 2 is arranged in the middle of the drying chamber 102. A storage tray 5 for carrying the fallen medicinal powder is provided at the bottom of the drying chamber 102, that is, below the drying tray 2 correspondingly. The hot air acts on the medicine on the drying tray 2 from top to bottom to dry the medicine.

[0021] Further, in the above solution, the hot air drying device 6 includes a housing 601 arranged at the top of the dryer main body 1 and a hot air pipe 602 arranged in the housing 601. The housing 601 fits with the top of the dryer main body 1 to form a hot air chamber 603. An air inlet pipe 604 is provided at the top end of the hot air chamber 603, and an air outlet pipe 605 communicating with the drying chamber 102 is provided at the bottom end of the hot air chamber 603.

[0022] In one implementation manner of the present utility model, the hot air of the hot air drying device 6 is transported from top to bottom into the drying chamber 102. The air outlet pipe 605 faces the drying bracket, and the hot air directly acts on the surface of the medicine to be dried, rapidly heating the medicine, which helps to quickly take away the water vapor evaporated from the surface of the medicine and improve the drying efficiency. In order to prevent the water vapor from condensing on the cold wall surface of the drying chamber to form water droplets, an exhaust fan assembly 7 is provided between the drying tray 2 and the storage tray 5 in the drying chamber 102. The water vapor between the drying tray 2 and the storage tray 5 is discharged through the exhaust fan to realize the circulation process of the hot air in the drying chamber, which is applicable to the situation where rapid drying is required and the medicine is relatively tolerant to temperature.

[0023] In another implementation manner of the present utility model, the hot air of the hot air drying device 6 is transported from top to bottom into the drying chamber 102. A baffle for blocking the hot air is provided above the drying bracket to prevent the hot air from directly acting on the surface of the medicine. In the initial heating state, when the hot air drying device 6 is in the working state, the exhaust fan assembly 7 is in the non-working state. The temperature in the drying chamber 102 is increased by the hot air of the hot air drying device 6. When the temperature in the drying chamber 102 reaches the predetermined drying temperature, the temperature is controlled by suction through the exhaust fan to prevent the medicine from overheating. By controlling the temperature of the drying chamber 102 through suction, a drying effect of multi-stage drying can be achieved.

[0024] Further, in the above solution, on the inner walls on both sides of the drying chamber 102, a first fixed guide rail 103, a second fixed guide rail 104, and a third fixed guide rail 105 are successively arranged from top to bottom.

During use, the heat insulation door 101 is opened, and the storage tray 5 is slid into the drying chamber 102 along the third fixed guide rail 105. The drying tray 2 is slid into a predetermined position along the second fixed guide rail 104. The baffle is selected to be slid into the drying chamber 102 along the third fixed guide rail 105 according to the characteristics of the drug and the requirements of the drying process;

[0025] Further, in the above solution, a swing assembly 3 for flipping materials is provided in the drying tray 2, including a swing rod 301 and a movable piece 302 sleeved on the swing rod 301. A plurality of movable pieces 302 hinged to the swing rod 301 are sleeved along the length direction of the swing rod 301. The movable pieces 302 on adjacent two swing rods 301 divide the drying tray 2 into a plurality of storage slots 202 for placing drugs. The height dimension of the movable piece 302 is greater than the height dimension of the drying tray 2. Therefore, when the swing rod 301 fits with the upper edge of the drying tray 2, the movable pieces 302 are arranged in the drying tray 2 in the same direction and inclined. The drugs are placed between the inclined movable pieces 302. After the driving assembly 4 drives the swing rod 301 to displace, the movable piece 302 follows the position adjustment of the swing rod 301 to adjust the inclination direction, thereby flipping the drugs.

[0026] Further, in the above solution, the drying tray 2 is a frame made of wire mesh. The drying tray 2 is provided with positioning strips 201 extending along the width direction of the drying tray 2 corresponding to the gaps between adjacent movable pieces 302 to form storage slots 202. The bottom end of the movable piece 302 is hinged to the drying tray 2, and the top end of the movable piece 302 is hinged to the swing rod 301, so that the movable piece 302 can flip the drugs in the storage slot 202 as the position of the swing rod 301 is adjusted, and fully dry both sides of the drugs.

[0027] In the connection structure between the swing assembly 3 and the drive assembly 4 of the utility model, a fixing groove 106 adapted to the end of the drying tray 2 is provided in the middle of the second fixed guide rail 104, and the fixing groove 106 is used to fix the end of the drying tray 2 to prevent the drying tray 2 from moving.
