Microcapsule granulation device

Abstract

The invention relates to a microcapsule granulation device. The microcapsule granulation system is provided with a granulation tower, a slurry supply pipeline, a drying fluidized bed, a finished product storage hopper, an encrusting auxiliary material storage hopper and a feed mechanism. Encrusting auxiliary material is delivered into the granulation tower through the bottom of the encrusting auxiliary material storage hopper; slurry enters a granulation head through the slurry supply pipeline and is thrown into the granulation tower to form innumerable spherical liquid beads; the spherical liquid beads are enwrapped by the encrusting auxiliary material, and water is extracted to form microcapsule granules; the microcapsule granules and most of the encrusting auxiliary material fall into the drying fluidized bed from the granulation tower to be dried for the second time, and the microcapsule granules and the encrusting auxiliary material are separated while drying, then the encrusting auxiliary material is delivered into the encrusting auxiliary material storage hopper for cyclic utilization; and the microcapsule granules enter the finished product storage hopper. The invention performs drying granulation through the encrusting auxiliary material. For general materials, the encrusting auxiliary material is heated to certain temperature through hot air for granulation according to the requirement, and for heat-sensitive and oxidizable materials, low-temperature granulation can be realized. The granule circular degree of the products is good, and the granulation effect is perfect.

Description

Technical field [0001] The invention relates to a microcapsule granulation device. Background technique [0002] Microcapsule technology is a technology that uses natural or synthetic polymer film-forming materials (wall materials) to embed liquid or solid drugs (capsule materials) to form microcapsule particles with a diameter of 100-5000μm. [0003] The process of preparing microencapsulated particles is called microencapsulation for short. It is widely used in industries such as additives, intermediates, pharmaceuticals, pesticides, food, environmental protection, petrochemicals, fine chemicals, and basic organic chemicals. The microencapsulation of the drug has many advantages: [0004] 1. It can reduce the contraindications between the drugs in the compound preparation, and isolate the reaction between the drug components. [0005] 2. Mask the bitter or peculiar smell of drugs, such as sulfa drugs. [0006] 3. Control the release of drugs. [0007] (1) For controlled or sustained...

AI Technical Summary

Problems solved by technology

This equipment is mostly produced in batches, which cannot meet the requirements of assembly line production, and the shape of the product particles is irregular. At the same time, the boiling granulation device also uses hot air to dry, and it is also helpless for heat-sensitive and easily oxidized materials.
