A pure powder granulating tablet press machine

Abstract

The invention provides a pure powder granulation negotiable machine and belongs to the field of medical instruments. The pure powder granulation negotiable machine comprises a feeding device, a roller pressing device, a granulating device and a negotiable device; the feeding device is located on the upper portion of the roller pressing device, and the granulating device is arranged between the roller pressing device and the negotiable device; the feeding device is provided with a feeding screw inside; the granulating device comprises a smashing mechanism and a granulating mechanism, and a discharging hopper is arranged below the granulating mechanism and is connected to the feeding port of the negotiable device. A radial blade and drum of the smashing mechanism are integrated as designed, a fixing bolt is arranged inside the drum, the end of the smashing mechanism is provided with the blade, the smashing dead corner is avoided, the integral production of granulating and negotiable is implemented, pure powder negotiable can be implemented, additives and water are omitted, and the producing efficiency can be improved effectively.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a pure powder granulation tablet press machine. Background technique [0002] At present, in the production process of pharmaceutical tablets, powder direct dry pressing and wet granulation are the most common production processes. However, many drugs are unstable under water and heat conditions. The performance is relatively poor, the production efficiency is low, and it is difficult to directly press the dry powder into tablets, and the pressed tablets are also easily broken. [0003] Therefore, people first press the dry powder into a block or a large tablet, and then crush the drug into particles of a suitable size, and then perform the tableting operation, which not only improves the fluidity of the drug during the tableting process, but also improves the tablet quality. The firmness of the agent. At the same time, the dry granulation tablet does not need to go through the p...
