Abstract

The invention relates to an external dry type granulator. The granulator comprises a transmission case body, wherein a transmission mechanism is arranged in the transmission case body; a material feeding mechanism, which is vertically arranged along the transmission box body; and a pair of granulating rollers, which is horizontally arranged along the transmission case body, and also comprises a material pushing mechanism, wherein the material feeding mechanism, the granulating rollers, and the material pushing mechanism are all arranged on the exterior of the transmission case body, the material feeding mechanism is fixed on the transmission case body, and is above the material pushing mechanism, the material outlet of the material feeding mechanism is communicated with the material pushing mechanism, the material pushing mechanism is fixed on the outer wall surface of the transmission case body, the material outlet of the material pushing mechanism is arranged between the two granulating rollers, and the first output shaft in the transmission case body goes through the wall of the transmission case body and is connected to the granulating rollers. In the external dry type granulator, the transmission chamber is separated from the granulating chamber so as to avoid the material contamination caused by splashed lubricant.

Description

technical field [0001] The invention relates to a granular material production equipment related to the fields of pharmacy, chemical industry, food and the like, in particular to an external dry granulator. Background technique [0002] With the deepening of the concept of quality from design, the research and development of pharmaceutical production process and pilot test are also more and more valued by the pharmaceutical industry, aiming to solve the current situation that many problems commonly exist in the process of pharmaceutical production process from experimental scale-up to mass production . Compared with traditional wet granulation, dry granulation has the ability to directly make powder raw materials into granular products that meet user requirements without any intermediates and additives. After granulation, the product has uniform particle size and significantly increased bulk density. It not only controls pollution, but also It also reduces powder and energy...
