China FL Series Boiling and Granulating Dryer - Top Suppliers and Factory for Efficient Powder Processing
Principle
The powder granule in vessel (fluid bed) appears the state of fluidization. It is pre heated and mixed with clean and heated air. At the same time adhesive is sprayed into the container. It makes some particles become granulating which contains adhesive. Being of unceasing dry through hot air, the moisture in the granulating is evaporated and the adhesive is solidification. The process is carried out continuously. Finally it forms ideal, uniform and porous granules.
Applications
Pharmaceutical industry: granular tablet, granule taken with water, granular capsule.
Foodstuff: cocoa, coffee, milk powder, juice of granule, flavoring and so on.
Other industries: pesticide, feed, fertilizer, pigment, dyestuff and so on.
Drying: for powder or granule damp material.
Coating: granule, pillprotection layer, pigmentation, controlled release, film, or bowels solved coating.

Frequently Asked Questions
What is the working principle of the FL Series Boiling and Granulating Dryer?
The powder granules inside the vessel are fluidized using clean and heated air. Simultaneously, an adhesive is sprayed into the container, causing the particles to aggregate. As hot air continuously dries the mixture, moisture evaporates, solidifying the adhesive to form uniform and porous granules.
What are the primary applications of this fluid bed dryer?
It is widely used in the pharmaceutical industry (for granular tablets and capsules), the foodstuff industry (for cocoa, coffee, milk powder, and juice granules), and other sectors like pesticides, fertilizers, and pigments. It is ideal for drying damp materials and applying protective or controlled-release coatings.
What is the temperature range and how is it controlled?
The operating temperature of the FL Series Boiling and Granulating Dryer is fully adjustable, ranging from room temperature up to 120℃, allowing you to customize settings based on the specific thermal properties of your raw materials.
What is the dust collection efficiency of this granulating dryer?
The equipment features an exceptionally high collect rate of ≥99%, ensuring minimal material waste, clean operation, and compliance with environmental and production safety standards.
How long does the granulating and drying process typically take?
The working time per batch is not fixed; it is decided and adjusted in accordance with the specific physical and chemical properties of the raw materials you are processing.
What utilities are required to operate the FL Series Dryer?
The system requires steam for heating (with a working pressure of 0.1~0.4 Mpa) and compressed air (with expenditure rates ranging from 0.6 to 1.5 m³/min depending on the specific model).
