     Overview of drying technology and basic application of boiling granulating dryer

     The boiling granulation should be an organic combination of mechanical design and preparation technology. The boiling granulation dryer is specially designed according to the characteristics of the material and the process requirements. Its drying technology uses powder granulation to improve fluidity and reduce dust flying;

     Powder granulation to improve its dissolving performance; mixing, granulating and drying in one machine to complete one-step granulation; using antistatic filter cloth, the equipment is safe to operate; the equipment has no dead corners, and the loading and unloading is light and fast, and it is cleaned to meet GMP specifications .

     Boiling granulation dryer can play a role in the following industries:

     Granulation in the pharmaceutical industry: tablet granules, granules, capsule granules;

     Granulation in the food industry: cocoa, coffee, milk powder, granulated juice, condiments, etc .;

     Granulation in other industries: pesticides, feed, fertilizers, pigments, dyestuff chemicals, etc .;

     Coating: granules, pill protective layer, coloring, sustained release, film, enteric coating, etc.

     The powder particles of the material in the boiling granulation dryer are in a circular fluidized state in the raw material container (fluidized bed). They are preheated and mixed by purified heated air, and the binder solution is atomized and sprayed to make a number of particles. Aggregates into binder-containing pellets. Due to the continuous drying of the material by hot air, the moisture in the pellets evaporates, and the binder solidifies. This process is repeated continuously to form ideal, uniform microporous spherical particles.

     Boiling granulation dryer is also suitable for:

     Granulation in the pharmaceutical industry: tablet granules, granules, capsule granules.

     Granulation in the food industry: cocoa, coffee, milk powder, granulated juice, condiments, etc. Granulation in other industries: pesticides, feed, fertilizers, pigments, dyestuff chemicals, etc. Drying of powdery or granular wet materials.

     Coating: granule, pill protective layer, color preparation, sustained release, film, enteric coating, etc.

     The structure of the boiling granulation dryer is a vertical cylinder with several layers of turntables inside. The material can be added from the top and dropped down to the bottom. The hot air is introduced from the bottom, and the air is circulated in sections by several blower turbines located in the center of the cylinder. A heater is installed on the inner wall of the device to supplement the heat of the air and improve the thermal efficiency and drying rate.
