Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of traditional Chinese medicine processing equipment, specifically a drying device for the production of traditional Chinese medicine decoction pieces. Background Technology
[0002] Drying of Chinese medicinal herbs is a crucial step in ensuring their efficacy stability and shelf life. The quality of drying directly affects the retention of active ingredients, color, and risk of mold growth. Existing drying equipment for Chinese medicinal herbs has several shortcomings in practical application: First, it suffers from poor drying uniformity. Traditional equipment often uses a single heat source or a fixed airflow path, resulting in a significant temperature difference between the stacked herbs and the surface, easily leading to localized over-drying or under-drying. This is especially true for multi-layered herbs, where uneven heat distribution at the bottom layer often results in low drying efficiency. Second, it has limited adaptability. Different Chinese medicinal herbs have significantly different requirements for drying temperature and humidity, but existing equipment often uses fixed parameter settings, making it difficult to flexibly adjust the process according to the type of herbs, potentially causing damage to active ingredients or excessively long drying cycles. Third, it has a low degree of automation, requiring frequent manual monitoring and adjustment during the drying process. Fourth, it lacks post-drying treatment. When high-temperature herbs are directly removed and stacked, residual heat can easily cause internal heat buildup, leading to discoloration and moisture reabsorption, affecting quality. These shortcomings make it difficult to meet the requirements of modern Chinese medicine production for high efficiency, precision, and environmental protection.
[0003] Therefore, those skilled in the art have provided a drying apparatus for the production of traditional Chinese medicine decoction pieces to solve the problems mentioned in the background art. Utility Model Content
