AI Technical Summary

Technical Problem

Traditional Chinese medicine decoction piece moisture detection devices have problems with heating uniformity and temperature control, resulting in inaccurate test results. Furthermore, unstable sample placement affects weighing accuracy, making it difficult to meet the high-efficiency and accurate testing requirements of modern Chinese medicine production.

Method used

A layered drying tank was designed, with heating wires and surrounding heating wires installed between the inner and outer walls. Combined with a blower and branch pipes, uniform heating and airflow agitation are achieved through unilateral air holes and ventilation holes. A cleaning brush is provided to maintain a dry environment, ensuring the accuracy of moisture detection and the stability of the equipment.

Benefits of technology

It achieves uniform heating of Chinese herbal medicine slices, improves the accuracy and efficiency of moisture detection, prevents water vapor accumulation, extends equipment life, and ensures the reliability of test results and the stability of samples.

Abstract

This utility model relates to the field of traditional Chinese medicine (TCM) decoction piece testing technology, specifically to a device for detecting the moisture content of TCM decoction pieces. The device includes a drying tank with a layered structure. A heating wire surrounds the inner and outer walls. The lower end of the inner wall has an inverted conical base, forming a ventilation chamber between the conical base and the outer wall. An electronic scale is located at the center of the bottom of the drying tank, with its upper tray penetrating the bottom. A lid is located on the top of the tank, and a blower is installed at the center of the lid. The blower's output is rotatably connected to a main air pipe, with several branch air pipes radially distributed around the main air pipe. This device detects the moisture content of TCM decoction pieces through the combined action of heating with the heating wire and blowing with the blower. The design of the single-sided air vents in the branch air pipes ensures that the airflow evenly covers the TCM decoction pieces, guaranteeing uniform drying and improving the reliability of the test results. A cleaning brush promptly removes residues and stains adhering to the inner wall of the tank during the testing process, preventing interference with subsequent tests.
