Abstract

The invention discloses a compression granulator which granulates more uniformly, and comprises a double-screw type extrusion feeding device in a handpiece and a discharging barrel which is matched with the extrusion feeding device, wherein the discharging barrel is sequentially provided with a collection tray with a central hole, a distribution part and an extrusion plate, the outer part of the extrusion plate is provided with a rotary cutter with an elastic part, distribution chutes are uniformly distributed at the feeding side of the distribution part, the discharging side of the distribution part is provided with a central boss and a support block, all the distribution chutes are converged at a discharging chute, the central hole has gradual diameter change, the discharge hole of the extrusion plate also has gradual diameter change, and cooling structures are respectively arranged on screws and spiral tubes of the double-screw type extrusion feeding device. The compression granulator uniformly discharges, can adapt to larger extrusion force, processes materials with larger viscosity, operates stably, has good reliability, and is particularly suitable for processing pharmaceutical particles.

Description

technical field [0001] The invention relates to a granulation equipment, in particular to a compressed granulator which performs granulation through template extrusion. Background technique [0002] At present, in the field of traditional Chinese medicine preparation processing, there are many kinds of granulation devices, and the commonly used one is mainly the screw extrusion granulator, which conveys the material through the screw and extrudes from the perforated template to form a material strand, and cuts the material strand to form particles. [0003] The Chinese invention patent application with the publication number CN1444917A published on October 1, 2003 discloses a "Chinese medicine pellet granulation device", which is composed of a mixing bin, a screw feeder, a splitting bin, a rotary cutter, etc. , there is a splitter plate between the splitter bin and the outlet of the screw feeder, the other end of the splitter bin is a discharge template, the splitter cone is...
