[0002] Granules are a common dosage form, which is made by granulating drugs or other active ingredients and mixing them with excipients;

[0003] Since the presence of moisture in granules may cause instability and decomposition of the preparation, drying can reduce the moisture content of the granules, thereby improving their stability and shelf life; The presence of moisture in granules may cause instability and decomposition of the preparation. Drying can reduce the moisture content of the granules, thereby improving their stability and shelf life;

[0004] Therefore, drying is an essential step in the preparation of granules. However, in current drying equipment, the heating component is located at the bottom of the box, and the air is drawn upward through the exhaust device to achieve the purpose of drying the granules. However, in this way, the temperature of the warm air will decrease during the upward rise, and the drying effect is not ideal for the granules on the upper layer. On the other hand, due to the small diameter of the granules, it is not convenient to place, pick up and transport them later. Utility Model Content

[0019] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figure 1-6 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the accompanying drawings.

[0020] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0021] 4. The hopper 24 is a bottom hopper 26 of the embodiment 1. The hopper 24 is a bottom hopper 27 of the embodiment 1. The hopper 24 is a bottom hopper 28 of the embodiment 1. The hopper 24 is a bottom hopper 26 of the embodiment 1. The hopper 24 is a bottom hopper 28 of the embodiment 1. The hopper 24 is a bottom hopper 28 of the embodiment 1.

[0022] When in use, first, place the granules into the placement box 5, and then place each placement box 5 into the placement box 5 of the placement bracket 3. Under the elastic force of the return spring 17, the pressing plate 6 and the placement box 5 are clamped in the placement bracket 3. Under the action of the pressing plate 6, the stability is further enhanced. When it is necessary to take it out, open the closing door 2 and take out the placement box 5.

[0023] The heating wire assembly 14 is controlled by the controller to generate heat. When the exhaust fan 8 is started, the cooperation between the heating wire assembly 14 and the exhaust fan 8 can form a warm air circulation in the drying box 1. Since the heating wire assembly 14 corresponds to the placement box 5, the generated warm air can pass through the air vents 22 provided on the placement box 5 to dry the granules in the placement box 5. The moisture is discharged through the air collecting hood 9 provided at the upper end of the drying box 1 and the exhaust duct, completing the drying work.

[0024] When placing the granules, open the buckle 21 and place the granules between the upper box 19 and the lower box 20. Then close the upper box 19 and the lower box 20 and lock them with the buckle 21. After drying, the granules can be transported by holding them in the placement box 5 as a whole, which is easy to carry and transport.

[0025] Example 2, based on Example 1, the inner wall of the drying box 1 is slidingly provided with a mounting plate 13 that cooperates with the filter box, the mounting plate 13 is provided with a heating wire assembly 14, the mounting plate 13 is slidingly connected to a positioning block 15, the rear end of the positioning block 15 is provided with an adjustment handle 16, a reset spring 17 is provided between the adjustment handle 16 and the mounting plate 13, and the inner wall of the drying box 1 is provided with a positioning hole 18 that cooperates with the positioning block 15.

[0026] When in use, it is necessary to debug the heating wire assembly 14, pull open the adjustment handle 16, overcome the elastic force of the return spring 17, and separate the positioning column from the positioning hole 18. At this time, the mounting plate 13 can be slid along the inner wall of the drying box 1 to the specified position, and the adjustment handle 16 is released. Under the action of the return spring 17, the positioning hole 18 cooperates with the positioning column to achieve the adjustment purpose, which is convenient for adjustment and easy to operate.

[0027] Embodiment 3, based on embodiment 1, a heat-resistant transparent plate 23 is provided on the closed door 2, through which the working conditions inside the drying box 1 can be observed.

[0028] The above description is only for the purpose of illustrating the present invention. It should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the scope of protection of the present invention.
