Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to an extruder for pharmaceutical use. Background Art

[0002] At present, the most widely used method for preparing small pellets is to use an extruder in combination with a spheronizer. The extrusion-spheronization method must use at least two machines, an extruder and a spheronizer, to complete the pelleting process. In the fields of medicine, chemical industry, fertilizer, feed, food, etc., micro-pellet production is an indispensable process. In the prior art, the commonly used methods for making micro-pellets are mainly panning and plasticizing. Sugar coating pan, tilted disc granulator, centrifugal granulation coating machine, fluidized bed tangential spray are the main equipment for panning micro-pellets; extrusion spheronization is a common method for plasticizing micro-pellets. Panning is to directly make micro-pellets from powder, which is inefficient, and the content of micro-pellet components is uneven when there are multiple components. For sticky materials, extrusion spheronization is generally used. Extrusion spheronization is to first obtain strip-shaped soft materials, and then enter the spheronizer to cut and centrifugally spheronize to obtain micro-pellets. It has a fast speed and a high yield rate
