Description

Technical Field

[0001] The utility model relates to traditional Chinese medicine drying equipment, in particular to a through-flow pill drying box. Background Art

[0002] In the traditional Chinese medicine processing industry, pill-shaped medicines are a common type. Among these medicines, some products must be dried in a natural state, such as honey pills and water-honey pills. The reason is that the extreme changes in temperature and humidity will destroy the efficacy of the medicine. However, in actual applications, the drying cycle of a batch is relatively long, exceeding 48 hours, which affects the production rhythm. At the same time, long-term drying will increase the risk of microbial contamination of the product; the product needs to be spread flat in the clean area, occupying a large area, affecting the production space in the clean area. In the current traditional technology, all artificial drying (such as ovens, vacuum drying, microwaves, etc.) requires heat to be transferred to the material being dried. Such equipment is not suitable for the process requirements of the product.

[0003] To solve the above problems, we made a series of improvements. Utility Model Content

[0021] The following is a further description of the present invention in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] Example 1

[0023] Figure 1 It is a structural schematic diagram of the utility model. Figure 2 It is a side view of the utility model. Figure 3 Schematic diagram of the air duct structure. Figure 4 A schematic diagram of the structure of a tray.

[0024] like Figure 1-4 As shown, a through-flow pill drying box includes: a box body 100, an inner liner 200, a box door 300, an air duct 400, a tray 500, a dehumidification system 600, a circulating fan 700 and a control system 800. The box body 100 is provided with an inner liner 200, the inner side of the inner liner 200 is provided with an air duct 400, the box door 300 is connected to the front of the box body 100, the tray 500 is fixed in the box body 100, the dehumidification system 600 and the circulating fan 700 are arranged on the top of the box body 100, and the dehumidification system 600 and the circulating fan 700 are connected to the control system 800;

[0025] Among them, the air duct 400 includes: a dehumidification air duct 410, a circulation air duct 420 and a balancing air duct 430. The dehumidification air duct 410 is connected to the dehumidification system 600. The dehumidification air duct 410 is arranged on one side of the box body 100, and the balancing air duct 430 is arranged on the other side of the box body 100. The circulation air duct 420 is connected to the circulation fan 700.

[0026] The circulation fan 700 includes: a circulation motor 710 and a circulation wind wheel 720 . The circulation motor 710 is fixed to the top of the box body 100 , and the circulation wind wheel 720 is connected to the transmission shaft of the circulation motor 710 .

[0027] The tray 500 is provided with ventilation holes 510 .

[0028] The dehumidification system 600 includes: a dehumidifier 610 and a guide plate 620 , and the guide plates 620 are provided at both ends of the dehumidifier 610 .

[0029] like Figure 1 and 2 As shown, the utility model itself does not have any heating structure, but uses a circulating fan to achieve the phenomenon of gas flow inside the box. The flow is also called forced convection. In the utility model, in order to ensure that the product is dried evenly naturally, the air duct 400 and the tray 500 with air holes 510 are passed through the box, so that the airflow can wrap the product during the drying process, making the pills dry more evenly. Figure 3 As shown, specifically, guide plates 620 for controlling the balanced flow of air are installed on the left and right sides of the box. The guide plate 620 on one side controls the air to enter the dehumidification system 600 along the dehumidification air duct 410. After dehumidification, the air enters the balanced air duct 430 along the guide plate 620 on the other side, so that the entire air flow cycle is balanced. The reason why balance is needed is that the circulating fan 700 will only flow air in one direction, and enter the circulating air duct 420 from one side to complete the air circulation of the entire box, so a balanced air duct 430 is needed. Through these air ducts, the airflow in the upper and lower parts of the box can be even. Figure 4 As shown, the tray is composed of a plurality of air holes 510. During the closed drying process of the device, the circulating fan guides the hot air to pass through the material layer evenly from bottom to top. Compared with the horizontal airflow, the hot air passes through the material layer evenly from left to right. The through-flow type makes the contact area between the hot air and the wet material larger, the internal moisture diffusion distance is short, and the drying effect is better.

[0030] The drying principle of the utility model is: to ensure the drying effect of the pills, the air in the box needs to be dehumidified. The drying box leads out an air duct in the overall circulating air duct 420, and then communicates with the dehumidification air duct 410 through the air duct, and then communicates with the dehumidification system 600 through the dehumidification air duct, and discharges moisture through the dehumidification system 600 to keep the box dry continuously. In combination with the cross-flow circulating air, the product drying effect is achieved. The dehumidification system 600 in the utility model is a traditional dehumidifier including: a compressor, an air suction system, a throttle valve and a dehumidification thermostat controller, so the description of its principle will not be expanded.

[0031] Compared with the traditional technology, the utility model simulates the environment of natural drying state and provides the pills with gas with low humidity and normal temperature for through-flow drying.

[0032] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
