Problems solved by technology

[0002] The preparation of spherical particles in the pharmaceutical, food and chemical fields can use a variety of processes, such as extrusion spheronization, extrusion spheronization, centrifugal granulation, fluidization Bedside spraying method, etc., each process method has its own characteristics and advantages. Extrusion spheronization method and extrusion spheronization method belong to plastic granulation technology. The process is simple and the particle size distribution of spherical particles is narrow. Centrifugal granulation method and The fluidized bed side spray method belongs to the pan-manufacturing granulation technology, and the process is relatively complicated, but the spherical particles have high roundness and can be prepared in layers; , Raw materials with a small proportion of auxiliary materials are not completely suitable for spherical particles with a small particle size range

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] figure 1 and figure 2 The automatic preparation machine for the spherical particle mother nucleus shown has an adjustable-speed spheronizing device, a binder spraying and atomizing device, a powder quantitative supply device, a particle generating device and an automatic control device.

[0016] Put a certain amount of raw material powder on the bottom of the water chestnut type rolling barrel, turn on the main motor, and drive the rolling barrel to rotate clockwise at a low speed. In the initial stage of preparation, the rolling barrel maintains a low speed of 5-10 rpm. After the belt particles are basically formed, set Set a high speed to make the particles round into a spherical shape. Turn on the spray gun, keep the spray pressure at 0.05-0.2MPa, spray the adhesive evenly on the inner wall of one side of the drum, control the flow rate of the adhesive at...

Abstract

A spherical particle parent nucleus automatic preparation machine is characterized by possessing a speed-adjustable rounding device, a binder spraying atomizing device, a powder quantitative supply device, a particle generating device and an automatic control device. The machine is capable of simulating the manual preparation process of the spherical particle parent nucleuses, and is especially suitable for spherical particle parent nucleuses prepared from powder with strong wettability, high viscosity and low auxiliary material ratio in medicinal, food and chemical raw materials. Prepared particles have the advantages of high finished product rate, high spherical degree, small particle size, narrow particle size distribution and the like.

Description

technical field [0001] The invention relates to an automatic preparation machine for spherical particle mother cores in the fields of pharmacy, food and chemical industry, in particular to a mechanical device capable of automatically preparing powders of medicine, food and chemical raw materials into spherical particle mother cores. Background technique [0002] The preparation of spherical particles in the pharmaceutical, food and chemical fields can use a variety of processes, such as extrusion spheronization, extrusion spheronization, centrifugal granulation, fluidized bed side spraying, etc. Each process has its own characteristics and advantages , the extrusion spheronization method and the extrusion rubbing method belong to the granulation technology of the plastic manufacturing method, the process is simple, and the particle size distribution of the spherical particles is narrow. It is more complicated, but the spherical particles have high roundness and can be prep...
