Embodiment Construction

[0017] Such as figure 1 As shown, a device for concentrating extracts in the preparation of traditional Chinese medicines comprises an upright container tank 1, the upper head of the container tank is connected to a negative pressure device, the lower head of the container tank is connected to a concentrated liquid discharge pipe, and the top of the inner chamber of the container tank is A liquid distribution device 2 for uniformly spraying the extraction liquid downward is provided, and a steam-heated serpentine tube bundle 3 is provided at the lower part of the inner cavity of the container tank.

[0018] In order to prevent corrosion and ensure the quality of the traditional Chinese medicine liquid, the inner wall of the container is enamelled.

[0019] In order to further increase the solute concentration, it also includes a circulating pump that extracts the bottom liquid of the container to the liquid distribution device.

Abstract

The invention provides a liquid extract condensing device in the traditional Chinese medicine preparation. The device comprises a vertically-arranged container tank, the upper seal head of the container tank is connected to a negative pressure device, the lower seal head of the container tank is connected to a liquid extract discharge pipe, the top of the internal cavity of the container tank is provided with a liquid distribution device that can evenly spray liquid extract downwards, and the lower part of the internal cavity of the container tank is provided with a steam-heated snake-shaped pipe bundle. Traditional Chinese medicine is extracted through decoction and then filtered to obtain liquid extract; the liquid extract is sprayed downwards from the liquid distribution device, when the liquid contacts with the steam-heated snake-shaped pipe bundle, dividing wall type heat transferring may happen, the liquid extract is heated, the solvent is evaporated, and the solute concentration is increased to form a concentrate. The heat exchange happens after the liquid extract is evenly sprayed, the heat exchange efficiency may be increased, the condensing speed is accelerated, and the production efficiency is high.

Description

technical field [0001] The invention relates to a device for concentrating extract liquid in the preparation of traditional Chinese medicine. Background technique [0002] Chinese medicine is becoming more and more important in the medical field. Compared with Western medicine, it is safe, has no side effects, and has the effect of treating the root cause. Most of Chinese medicine comes from natural plants, followed by animals, minerals and some artificial products. The efficacy of many Chinese herbal medicines has not only withstood the test of long-term medical practice, but also has been confirmed by modern scientific research. The active ingredients and molecular structures of some Chinese herbal medicines have also been fully or partially studied. In order to guarantee the curative effect of the drugs, our working people have accumulated abundant experience in the cultivation, harvest, processing, processing, storage, and keeping of drugs through the long-term practi...
