[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Combination Figures 1 to 3 A pharmaceutical dryer shown in the figure comprises a box body 1 and a drying chamber 11 opened in the box body 1. A box door 2 is provided on the side of the box body 1 and is connected by a rotating shaft. A rotating shaft 3 is vertically provided on the inner side of the drying chamber 11. A plurality of trays 4 are equidistantly provided on the outer side of the rotating shaft 3 and are connected by screws. Transmission mechanisms 5 are provided at both ends of the rotating shaft 3. Heating rods 6 are provided on both sides of the tray 4. A plurality of dehumidification components 7 are equidistantly provided on the inner side of the box door 2. A first mounting plate 12 and a second mounting plate 13 are provided on the inner side of the drying chamber 11. An air pump 8 is provided above the first mounting plate 12. The dryer uniformly heats the medicines on the trays through the heating rods 6 provided on both sides of the trays 4. At the same time, the medicines can be fully dried at all angles through the rotation of the trays on the rotating shaft 3, thereby improving the drying efficiency.

[0020] The first mounting plate 12 and the second mounting plate 13 are both connected to the box body 1 through screws, and the first mounting plate 12 is penetrated by the rotating shaft 3 and connected through the rotating shaft.

[0021] The dehumidification component 7 includes an installation box 71, which is connected to the box door 2 by screws. A flip cover 72 is provided at one end of the installation box 71 and is connected to the buckle by a hinge. A plurality of ventilation holes 73 are provided on one side of the installation box 71. A water-absorbing resin rod 74 is installed on the inside of the installation box 71. The dehumidification component 7 arranged on the inside of the box door 2 can effectively absorb moisture in the box and maintain a dry environment in the drying chamber 11. The water-absorbing resin rod 74 has a strong moisture absorption capacity to ensure that the medicines will not be affected by the evaporated moisture during the drying process.

[0022] The transmission mechanism 5 includes a first transmission box 51 and a second transmission box 52. The first transmission box 51 and the second transmission box 52 are respectively located at the two ends of the rotating shaft 3. The first transmission box 51 and the top of the first mounting plate 12, and the second transmission box 52 and the second mounting plate 13 are all connected by snaps. A motor 53 is provided under the second mounting plate 13 and is connected by screws. The output end of the motor 53 passes through the second mounting plate 13 and is connected to the second transmission box 52 for transmission. The transmission mechanism 5 drives the second transmission box 52 through the motor 53, thereby driving the rotating shaft 3 and the tray 4 to rotate, thereby realizing the rotary drying of the medicine. The motor-driven transmission mode is stable and reliable, ensuring that the dryer can operate stably for a long time.

[0023] The vacuum pump 8 is connected to the first mounting plate 12 by screws, the input end of the vacuum pump 8 passes through the first mounting plate 12 and is fixed by a buckle, and the output end of the vacuum pump 8 passes through the side wall of the box 1 and is fixed by a buckle. The setting of the vacuum pump 8 can extract the humid air in the drying chamber 11, further improving the drying effect.

[0024] Working principle: When the utility model is in use, the medicines or raw materials to be dried are placed in the tray 4, and after closing the box door 2, the heating rod 6 is turned on for heating, and the vacuum pump 8 is turned on to extract moisture. At the same time, the absorbent resin rod 74 absorbs the residual water vapor in the drying chamber 11 to prevent the medicines from being damp and degraded due to the absorption of evaporated water vapor.
