Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and more specifically, to a dryer. Background Technology

[0002] The value of drug drying technology far exceeds that of simple water removal; it is a crucial barrier to ensuring the stable quality of medicines throughout the entire process from production to use. By precisely controlling the moisture content, not only are risks such as mold and spoilage during storage eliminated, but the concentration effect also optimizes the stability and bioavailability of drug components, ultimately ensuring the safety and efficacy of the medicine and directly enhancing the product's core competitiveness.

[0003] Existing dryers still have the following problems: Current hot air conveying systems in drying equipment have significant limitations. Airflow can only enter the drying chamber from a fixed direction, resulting in uneven heat distribution within the chamber. Some materials are exposed to high-temperature airflow for extended periods, causing rapid localized moisture evaporation, while other areas do not receive sufficient heat exchange. This ultimately leads to inconsistent drying quality, affecting the overall quality of the finished product. Furthermore, existing drying devices lack effective material agitation. The material is heated in a static environment, resulting in rapid surface drying but difficulty in removing internal moisture. This not only significantly prolongs the required drying time and reduces efficiency but also makes the material prone to agglomeration and hardening, causing inconvenience for subsequent processing steps.

[0004] In view of this, we propose a dryer. Utility Model Content

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a dryer with the following advantages: 1.

The fan 19 is fixedly connected to the support shell 15.

[0023] Please see Figure 4 and Figure 6 The agitation structure includes equally spaced discs 20, with equally spaced circumferentially spaced guide rails 21 fixedly connected to the discs 20, and a lever 22 slidably connected to the guide rails 21; a sliding rod 23 is slidably connected to the middle of the rotating sleeve 7, and the rotating sleeve 7 is provided with spaced through slots; a sliding sleeve 24 is slidably connected to the rotating sleeve 7, and the sliding sleeve 24 slides within the through slots of the rotating sleeve 7, and the sliding sleeve 24 is fixedly connected to the sliding rod 23; a hinge rod 25 is hinged between the sliding sleeve 24 and the lever 22; an electric push rod 26 is fixedly connected to the top cover 3, and the telescopic end of the electric push rod 26 is fixedly connected to the sliding rod 23.

[0024] The working principle of this utility model: Place the material in the tray 10, then open the closing door 4, pull down the spline sleeve 8, the spline sleeve 8 slides down along the rotating sleeve 7, the spring 9 is compressed, then insert the tray 10 and the connector 11 into the rotating sleeve 7, then insert the limiting post 12 into the through hole of the spline sleeve 8, then release the spline sleeve 8, the spline sleeve 8 supports the connector 11 by the elastic force of the spring 9, the tray 10 is supported by the spline sleeve 8, place the tray 10 into the fixed shell 2 in sequence, then close the closing door 4, start the fan 19 and the heating wire 18, the fan 19 blows air into the support shell 15, the air is heated by the heating wire 18 and blown into the fixed shell 2 along the air guide pipe 17, the hot air dries the material on the tray 10, and then the hot air is discharged through the exhaust pipe 5.

[0025] When drying the material on the tray 10, the motor 13 is started. The output shaft of the motor drives the rotating sleeve 7 to rotate. The rotating sleeve 7 drives the connecting piece 11 and the tray 10 to rotate circumferentially through the spline sleeve 8, thereby improving the uniform contact between the hot air and the material on the tray 10 and improving the drying effect of the material.

[0026] During the drying process, the rotating sleeve 7 drives the disc 20 and the sliding sleeve 24 to rotate synchronously. The electric push rod 26 is activated, causing its telescopic end to move up and down reciprocally. The telescopic end of the electric push rod 26 drives the sliding rod 23 to move up and down along the rotating sleeve 7. The sliding rod 23 drives the sliding sleeve 24 to move synchronously. The sliding sleeve 24 pulls the actuating element 22 along the guide rail 21 through the hinge rod 25. At this time, the actuating elements 22 move closer to each other. When the sliding sleeve 24 moves downward, the actuating rods move further apart. The actuating element 22 actuates the material in the tray 10, changing the original accumulation state of the material, allowing hot air to flow from the gaps in the material, improving the drying efficiency of the material, and reducing material caking.
