Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] The extraction process of traditional Chinese medicine is carried out in the extraction tank. Steam inlet valves are arranged on the steam inlet pipes of the upper jacket, lower jacket and tank bottom jacket of the extraction tank. The steam pipeline of the extraction tank is provided with a steam regulating valve. An upper and lower double-point temperature transmitter is arranged in the extraction tank. A temperature sensor is arranged in the extraction tank.

Abstract

The invention discloses a temperature stability control method during the extraction process of traditional Chinese medicines. The temperature stability control method comprises the steps: starting a steam inlet valve on an extraction pot, and adjusting the opening degree of a steam adjusting valve according to a function K=0.18(T-T0) / t*100% so as to guarantee the stability of the temperature rise time; entering an insulation and decoction phase when the temperature in the extraction pot achieves a set extraction temperature, and adjusting the opening degree of the steam adjusting valve according to the difference between the detection temperature TS in the pot and a set insulation and decoction temperature T1 so as to guarantee the temperature stability during the insulation and decoction phase; and finishing decoction when the time of insulation and decoction achieves a set insulation and decoction time t1. Through the above mode, the temperature stability control method during the extraction process of traditional Chinese medicines realizes accurate control of the temperature rise time and the temperature during the extraction process of traditional Chinese medicines, and reduces the difference between batches during the extraction process of traditional Chinese medicines, and can provide a new technology for improvement of quality stabilization of traditional Chinese medicine products and modernization of traditional Chinese medicines.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine extraction technology in traditional Chinese medicine pharmacy, in particular to a method for controlling temperature stability during the extraction process of traditional Chinese medicine. Background technique [0002] The extraction process of traditional Chinese medicine is the process of dissolving the active ingredients in traditional Chinese medicine from plant tissues with an appropriate solvent. The heating rate of the extraction process temperature and the extraction temperature directly affect the dissolution rate of the active ingredients. If the temperature is too low, the extraction of the active ingredients will be incomplete and the final product will be unqualified; if the temperature is too high, the heat-sensitive ingredients may be decomposed. , It may even cause the liquid medicine to fry, and eventually lead to unqualified products. The extraction time also direct...
