Abstract
Description
Technical Field
[0001] This utility model relates to a low-temperature drying and dehumidification device, belonging to the field of low-temperature drying and dehumidification technology. Background Technology
[0002] The low-temperature drying technology primarily utilizes a self-developed dry air system, which significantly revolutionizes traditional electric heating methods for evaporating moisture. This technology effectively preserves the original aroma, nutrients, and active ingredients of the materials, while mitigating the effects of high temperatures on the solution, such as aroma loss, nutrient degradation, and cell death due to excessive heat. The efficient use of dry air circulation in this technology saves energy and simultaneously dries the materials more thoroughly.
[0003] The following are existing drying methods for Chinese medicinal herbs: 1. Sun-drying: This method involves spreading the herbs flat on thin reed mats or cleaned cement floors and exposing them to sunlight until fully dry. Sun-drying is low-cost and easy to operate, but because the external environment cannot be controlled during the process, the herbs are susceptible to damage. Furthermore, the drying time is long, and it's difficult to scientifically and effectively determine the moisture content after drying, thus failing to guarantee that the moisture content meets the requirements of the pharmacopoeia. 2. Shade-drying: Shade-drying involves air-drying the herbs in a cool, well-ventilated place. The principle is to utilize the natural flow of air and wind to remove free moisture, thereby achieving the drying purpose. This method is often used for herbs containing volatile oils and those prone to oil loss or discoloration. Both shade-drying and sun-drying have the advantages of being simple to operate and low-cost, but shade-drying takes a long time and the herbs can become contaminated. Utility Model Content
[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a low-temperature drying and dehumidification device.

The small fan can rotate 0-150 degrees via the T-shaped connector and U-shaped base. The lighting uses an infrared heating lamp, whose temperature exceeds 100°C when in operation. The fan evenly disperses hot air and hot air downwards onto the support platform and the grid surface. The lighting and the grid surface are 100cm apart, facilitating the drying and dehumidification of materials placed on the grid surface.
