Novel vertical granulator for pharmaceutical preparation manufacturing

Abstract

The invention provides a novel vertical granulator for pharmaceutical preparation manufacturing. The granulator comprises a grinding box, a transmission box, a discharging box, a cutting pipe, a feeding hopper and a granulating cylinder. The transmission box and the discharging box are fixedly connected to the centers of the upper end and the lower end of the grinding box. The grinding box is communicated with the transmission box and the discharging box. The right front end of the transmission box is fixedly connected with the cutting pipe, and the feeding hopper is fixedly connected to the center of the right side of the top of the cutting pipe. The granulating cylinder is fixedly connected to the center of the rear end of the bottom of the discharging box. Throwing assemblies are fixedly connected to the positions, which are on the left side and the right side of the upper end of a stirring runner, of a second connecting shaft. The top of the granulating cylinder is communicated with the discharging box. Guide plates are fixedly connected to the left side and the right side of the lower end of a second blanking opening in the discharging box. A discharge hole is formed in the bottom of the granulating cylinder. According to the novel vertical granulator for pharmaceutical preparation manufacturing, the problems that raw materials of an existing granulator are prone to adhering to the interior, raw material losses are caused, meanwhile, the grinding efficiency is low, and the production efficiency is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of granulator, in particular to a novel vertical granulator used for the manufacture of pharmaceutical preparations. Background technique [0002] In the process of pharmaceutical and food manufacturing, especially the manufacture of tablets or granules, granulators are generally used. The current granulators are generally horizontal structures, which are bulky and occupy a lot of space on the bottom surface. It is not high. When crushing and grinding the raw material of the drug, the drug is easy to adhere to the upper end of the blade. At the same time, the grinding efficiency is slow, which reduces the production efficiency. The drug cannot be dried during granulation, which makes the drug easy to adhere to the upper end of the granulation screen Causes problems that are difficult to clean. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides...
