Equipment for preparing Chinese medicine granules by freeze-drying method and method for preparing Chinese medicine granules

Abstract

The invention discloses a method and a device for preparing traditional Chinese medicine particles through a freeze pelletizing drying method. The device for preparing the traditional Chinese medicine particles through the freeze drying method comprises a freezing cabin 1, a spraying nozzle 2, a fluidization wind distribution plate 3, an exhaust system 4, a vibrating device 5 and a freezing medium bucket 8; the freezing cabin 1 is formed by a cover 11 and a bottom cabin 12; the cover 11 and the bottom cabin are flexibly connected; the top of the cover 11 is provided with a circular hole 13; the spraying nozzle 2 which is connected with a vibration device 5 is arranged above the circular hole; the cover 11 is connected with the exhaust system; the fluidization wind distribution plate 3 is arranged on the middle lower portion of the bottom cabin 12; the spraying nozzle is connected with a material bucket through a pipeline; the bottom of the bottom cabin 12 is connected with the freezing medium bucket 8 through a pipeline; the top of the freezing medium bucket 8 is provided with a freezing medium inlet-outlet pipe 9 and a high pressure gas inlet pipe 10. The device for preparing the traditional Chinese medicine particles through the freeze drying method has the advantages of overcoming the disadvantages that the existing traditional Chinese medicine particle production technology is high in accessory dependency, combining vibrating mist spraying freezing solidification and fluidized drying, enabling the traditional Chinese medicine particles to be controlled to be uniform, regular and good in mobility.

Description

technical field [0001] The invention relates to traditional Chinese medicine preparation equipment and methods, in particular to a preparation equipment and method for traditional Chinese medicine granules with wider material applicability and lower dependence on auxiliary materials. Background technique [0002] Traditional Chinese medicine granules are a commonly used traditional Chinese medicine preparation, which has the characteristics of convenient administration, fast absorption, and simple storage and transportation. The traditional production process of traditional Chinese medicine granules generally uses methods such as decoction to extract, purify and concentrate the original medicinal materials to obtain the liquid extract or extract required for the preparation of granules, and then use methods such as extrusion, sieving, fluidized drying, etc. Granulation. In addition, traditional Chinese medicine granules can be further processed to prepare other medicines in...

Problems solved by technology

[0005] At present, the heating process is commonly used to dry traditional Chinese medicine granules, but because Chinese medicine extracts usually contain polysaccharides, it is difficult to dry the viscous traditional Chinese medicine extract under heating, and it is easy to harden and coke, so a large amount of auxiliary materials need to be added Improve granulation drying molding and dispersion performance
