Online quick detection method of moisture in traditional Chinese medicines of animal glues

Abstract

The invention discloses an online quick determination method of moisture in traditional Chinese medicines of animal glues. The method comprises the following steps of: 1) performing zero calibration for a microwave moisture detection instrument to zero, namely, performing zero calibration in dry air and water; 2) calibrating the moisture value coefficient through the microwave moisture defection instrument, namely, collecting tpAve values of a plurality of samples, detecting the moisture values of the samples by drying method, and enabling the tpAve values of the samples to be associated with the moisture value; and 3) testing the tpAve value of the a sample to be detected through the microwave moisture detection instrument on line, so as to obtain the moisture value of the sample to be detected on line. According to the online quick detection method, the microwave moisture detection instrument is utilized to quickly detect the moisture on line during producing the traditional Chinese medicines of animal glues; and the tpAve values of the traditional Chinese medicine materials of semi-fluid glues which are of high temperature, high viscosity and deep color are detected based on the microwave theory and then are associated with the moisture value detected by the drying method and calibrated. The online quick detection method of moisture in the traditional Chinese medicine materials of semi-fluid glues is convenient, fast in speed and accurate.

Description

technical field [0001] The invention relates to a method for quickly measuring the online water content in the rubber-making process of traditional Chinese medicine of animal glue based on microwave principle, and belongs to the technical field of traditional Chinese medicine production. Background technique [0002] Animal glue traditional Chinese medicine is one of the main components of traditional Chinese medicine. It has been used in China and has a documented history of more than 2,500 years. It has good disease treatment and nourishing health care value. The key processes in the production of animal glue traditional Chinese medicine include glue melting, filtration, foam extraction, rubber mixing, glue discharging and drying, among which rubber mixing is one of the most critical processes for the quality of the glue. In this process, the moisture content of the glue paste is Rapid detection is an important quantitative index to evaluate the degree of rubber mixing, an...

Problems solved by technology

[0003] At present, the methods for determining the moisture content of traditional Chinese medicine mainly include drying method, distillation method, Karl Fischer method (coulomb method), ultrasonic method, infrared absorption spectroscopy and high-frequency attenuation method, etc., among which drying method, distillation method and Karl Fischer method , it takes a long time, the operation is complicated, and the reagent consumption is large, etc., all of which cannot realize the rapid monitoring of online moisture.

Ultrasonic method and near-infrared absorption spectroscopy are used to measure the mixing degree of donkey-hide gelatin and the water content of the gelatin. Due to the dark color and high viscosity of the test material, it is easy to adhere to the detection probe, resulting in no signal display or a relatively weak signal in the measurement. The error of the measurement result is relatively large; the high-frequency attenuation method has a great influence on the attenuation of high-frequency electromagnetic waves emitted by the detector probe to the surroundings due to the high-frequency attenuation method. The signal received by the sensor is relatively weak, and the error of the measurement result is relatively large.
