Abstract

This application relates to a method and device for controlling the moisturizing process of medicinal materials. The medicinal material moisturizing device includes a medicinal box, a vacuum pump and a vacuum pressure sensor connected to the inner cavity of the medicinal box. The medicine moistening rack on the load cell, the vacuum pressure sensor, the load cell and the controller are connected in communication, and the moisture content detection model corresponding to the moist medicinal materials is stored in the controller; the method for controlling the medicinal material moistening process includes the following steps: adding the medicinal materials to In the moistening medicine box, when the decompression in the moistening medicine box is reduced to negative pressure, steam is passed into the moistening medicine box to moisten the medicinal materials; the weight data of the medicinal materials collected by the weighing sensor and the moistening medicine box collected by the vacuum pressure sensor The vacuum degree data in the machine is transmitted to the controller, and the controller calculates the moisture content of the moistened medicinal materials in real time according to the moisture content detection model, and judges whether the moistening end point has been reached, realizing the real-time monitoring of the moistening process and the rapid judgment of the moistening end point.

Description

technical field [0001] The application belongs to the technical field of medicinal material production, and in particular relates to a method and device for controlling the moistening process of medicinal materials. Background technique [0002] Chinese herbal medicines must be processed into Chinese herbal decoction pieces before they can be used for clinical dispensing of traditional Chinese medicine and as raw materials for the production of preparations. The processing of Chinese herbal medicines into decoction pieces generally needs to go through three processes, namely, cleaning, cutting, and processing. Traditional Chinese medicinal materials generally need to be softened before cutting, and moistening is a relatively common softening method. Moisturizing mainly involves soaking medicinal materials with an appropriate amount of water so that they can fully absorb water and soften them for cutting. The quality of the moisturizing medicine directly affects the appearan...
