Medicine granule production system

Abstract

The invention discloses a medicine granule production system. The key point of the technical scheme of the medicine granule production system is that the medicine granule production system comprises a vertical installation frame, a wet mixing granulator, a wet straightening granulator, a fluidized bed and a dry straightening granulator, and the wet mixing granulator, the wet straightening granulator, the fluidized bed and the dry straightening granulator are arranged sequentially from the top down on the vertical installation frame; a transfer hopper is arranged over the feed inlet of the wet mixing granulator; an air-replenishing assistor which is used for driving medicine granules to get into the fluidized bed is arranged between the wet straightening granulator and the fluidized bed; a turning discharge valve is arranged at the discharge outlet of the fluidized bed; a discharge bin valve is arranged at the feed inlet of the dry straightening granulator, and a discharge bin is arranged between the turning discharge valve and the discharge bin valve; a mixing hopper is arranged under the discharge outlet of the dry straightening granulator. The system utilizes gravity to transfer materials, and the process of the whole medicine granule production system drops the materials from high positions to low positions rather than pumps the materials from the low positions to the high positions, consequently, the structure of the system is simple, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of medicine production, more specifically, it relates to a medicine granule granulation system. Background technique [0002] Granulation is the process of agglomerating finer particles into coarse powder clumps to improve powder flowability. Through granulation, the operation of processing materials in the state of powder, molten liquid or aqueous solution into granular objects with a certain shape and size. The preparation process of almost all solid preparations is inseparable from the granulation process. The resulting granules may be final products such as granules. [0003] The existing granulation system is mainly composed of pharmaceutical equipment such as wet mixing granulator, wet granulator, fluidized bed, dry granulator, etc. These pharmaceutical equipment are usually arranged horizontally in order, and each pharmaceutical equipment The discharge port will be connected with the feed port of the adjacen...

Problems solved by technology

[0003] The existing granulation system is mainly composed of pharmaceutical equipment such as wet mixing granulator, wet granulator, fluidized bed, dry granulator, etc. These pharmaceutical equipment are usually arranged horizontally in order, and each pharmaceutical equipment The discharge port will be connected with the feed port of the adjacent pharmaceutical equipment to realize material transfer, but the discharge port of the pharmaceutical equipment will be lower than the feed port of the adjacent pharmaceutical equipment, so that there is a need between two adjacent pharmaceutical equipment Set up a "low to high" pumping drive device to realize material transfer, which makes the structure of the granulation system complex and the cost of equipment investment is high
