What are the applications of fluidized bed dryers?

2026,02,09

A fluidized bed dryer, also known as a Boiling Dryer, generally consists of a heater, a fluidized bed unit, a cyclone separator, a bag filter, an induced draft fan, and an operating platform. Depending on the properties of the material, a cyclone separator or a bag filter can be selected as needed.

Working Principle

The fluidized bed dryer utilizes air heated by a heat exchanger to form hot air, which is then distributed into the main unit via a valve plate. Wet material enters the dryer through the feeder. Due to the air pressure, the material enters a boiling state within the dryer, making extensive contact with the hot air, thus drying the material in a relatively short time.

Features

Improves flowability and reduces dust emissions through powder granulation;

Improves solubility through powder granulation;

One-step granulation process combining mixing, granulation, and drying;

Uses anti-static filter cloth for safe operation;

Features include a pressure relief vent to prevent personnel injury in the event of an explosion;

Equipped with no dead zones, allowing for easy and quick loading and unloading, and thorough cleaning, meeting GMP standards.

Applications

Physical industry granulation: tablet granules, powder granules, capsule granules.

Food industry granulation: cocoa, coffee, milk powder, fruit juice granules, seasonings, etc.

Other industries granulation: pesticides, feed, fertilizers, pigments, dyes, chemicals, etc.

Drying of powdery or granular wet materials.

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

Equipment Classification

Based on shape, it is divided into two main categories: horizontal and vertical. Horizontal is also known as a box-type fluidized bed dryer, and vertical is also known as a high-efficiency fluidized bed dryer. The working principle of horizontal and vertical dryers is the same.

Applicable Materials

Powdered and granular materials in the pharmaceutical, chemical, and food industries.
