Embodiment 1

[0034] This embodiment provides an online control device for moisture in the drying process of Chinese herbal medicines, such as figure 1 As shown, it includes: a drying box 1, a temperature and humidity sensor 2 connected to the inner cavity of the drying box 1 is arranged outside the drying box 1, and a transmission mesh belt 3 for transmitting Chinese medicinal materials is installed in the drying box 1 and is located in the drying box 1. The spectrophotometer 4 above the end of the conveying mesh belt 3 in the transmission direction. The drying box 1 is communicated with a heating mechanism that provides dry hot air to it. Heater, the inlet of the air heat exchanger communicates with the blower fan 6, the air heat exchanger is provided with a steam heating pipe, the inlet pipe of the steam heating pipe is connected to the steam input pipe, and the outlet pipe of the steam heating pipe is connected to A steam trap, the steam input pipe is provided with a steam regulating va...

Embodiment 2

[0042] This embodiment provides a method for online moisture control in the drying process of loquat leaves, comprising the following steps:

[0043] Step 1: Establishment of moisture content detection model

[0044] 1) Get 100 parts of loquat leaf shreds to be dried in different batches, divide them into 10 groups, and dry them for 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, and 35 minutes through the online control device for the drying process of Chinese medicinal materials described in Example 1, respectively , 40min, 45min, and 50min, take it out, and record the real-time data collected by the controller: the color difference value ΔE*ab value of the Chinese herbal medicine to be tested and the Chinese herbal medicine with the target moisture content, the temperature T (°C) in the drying oven 1 and Relative humidity RH (%), where: the diameter of the observation area of ​​the spectrophotometer is 100mm, the diameter of the measurement area is 25...

Abstract

The application relates to an online moisture control method and device in the drying process of Chinese herbal medicines. The device includes: a drying box, a temperature and humidity sensor connected to the inner cavity of the drying box is arranged outside the drying box, a transmission mesh belt is installed inside the drying box, and a conveyor belt is located in the drying box. The spectrophotometer above the end of the transmission direction of the mesh belt, and the drying box is connected with a heating mechanism that provides dry hot air to it; the temperature and humidity sensor, the spectrophotometer and the controller are connected by communication, and Chinese medicinal materials are stored in the controller Moisture content detection model; the method is: separately measure the color difference between multiple samples of Chinese medicinal materials transported to the end of the transmission direction by the transmission mesh belt in the drying oven and the Chinese medicinal materials with the target moisture content, and measure the temperature and humidity in the drying oven at the same time ; Measure the moisture content of a plurality of Chinese herbal medicine samples by drying method respectively; Adopt the partial least squares method to establish the moisture content detection model between the color difference value, temperature and humidity and the moisture content, to detect the Chinese herbal medicine to be tested moisture content.

Description

technical field [0001] The application belongs to the technical field of traditional Chinese medicine pharmacy, and in particular relates to an online moisture control method and device in the drying process of Chinese medicinal materials. Background technique [0002] The processing of Chinese herbal medicines is directly related to the quality and efficacy of Chinese herbal medicines. Scientific and reasonable processing can play a role in reducing toxicity and increasing efficiency, while unscientific and unreasonable processing will often cause the active ingredients of medicinal materials to be lost, and even produce toxic and side effects. The level of processing is related to the content, form and solubility of active ingredients in Chinese herbal pieces, and the degree of processing directly affects the curative effect of Chinese herbal pieces. Therefore, the processing of Chinese herbal pieces is crucial to the quality of Chinese herbal pieces and their preparations...
