Embodiment 1

[0009] The company's golden rooster ointment production experiment example adopts the process of plant medicinal material preparation process, soaking process, extraction process, extract concentration process, and paste product in the prior art; it is characterized in that: the process conditions of the extract concentration process are as follows: Water is used as the heating medium, and the temperature of the heating medium does not exceed 103°C; the concentration of the extract is controlled under vacuum at 0.06-0.08Mpa.

Embodiment 2

[0011] The company's golden rooster ointment production experiment example adopts the process of plant medicinal material preparation process, soaking process, extraction process, extract concentration process, and paste product in the prior art; it is characterized in that: the process conditions of the extract concentration process are as follows: Water is used as the heating medium, and the temperature of the heating medium does not exceed 99°C; the concentration of the extract is controlled under vacuum at 0.06-0.08Mpa.

Embodiment 3

[0013] The company's golden rooster ointment production experiment example adopts the process of plant medicinal material preparation process, soaking process, extraction process, extract concentration process, and paste product in the prior art; it is characterized in that: the process conditions of the extract concentration process are as follows: Water is used as the heating medium, and the temperature of the heating medium does not exceed 95°C; the concentration of the extract is controlled under vacuum at 0.06-0.08Mpa.

[0014] Above embodiment, all do not produce the phenomenon of scorch, and gained ointment and its further processing into products including tablet, capsule, granule, drop pill, oral liquid, decoction etc., its quality is all better than original process method product . (In the quality control method, the identification method has good reproducibility, negative and no interference; the content determination method is based on the test results and shows t...

Abstract

The invention relates to an internal circulation low-temperature single effect vacuum concentration method for traditional Chinese patent medicines. The process conditions of an extract concentration process is that water is used as a heating medium, and the temperature of the heating medium is no more than 95 to 103 DEG C, and concentration vacuum is controlled between 0.06 and 0.08 MPa. Circulating hot water is used as the heating medium, the temperature is adjustable, a whole heater is heated uniformly so as to achieve an effect of low-temperature concentration, so that problems of coke breeze generation caused by local high temperature of the heater can be prevented and the quality of a condensed extract is guaranteed; low-temperature concentration does not break the characteristics of the medicine(physical properties such as dissolubility and chemical properties such as heat sensitivity), so that the product quality of medicinal preparations can be controlled effectively, and the efficacy of medicines can be guaranteed; at the same time, the low-temperature single effect vacuum concentration method is suitable for resisting explosion or preventing high temperature operation areas; and by adopting a hot water circulating solution, the method has the advantages of low heat loss, high heat utilization rate and remarkable energy-saving effect.

Description

technical field [0001] The invention belongs to a production and processing method of a Chinese patent medicine, in particular to a method and equipment for concentrating a Chinese patent medicine. Background technique [0002] At present, the pharmaceutical industry concentrates liquid medicine, and the internal circulation single-effect vacuum concentration device with steam heating is widely used in time. Because the single-effect inner heating tube is in a circular layout, there is only one steam inlet, and the steam temperature is relatively high. The steam pressure produced is all above 0.2Mpa, that is, the corresponding temperature is above 120°C; the temperature difference between the heating medium and the liquid medicine is too large and the influence of local high temperature, especially when the liquid medicine is concentrated to a thick paste with a relative density of 1.28-1.33, Very prone to scorching. The prior art has the disadvantage that it is easy to gen...
