Applications
Wet granules and powders for pharmaceutical, food, chemical and feed production.
Applications include wet granules and powders for pharmaceutical, food, chemical and feed production. Confirm material properties and process conditions before selecting the equipment configuration.
Food Industry
Food granules, nutritional ingredients and powder materials.
Chemical Industry
Chemical granules, fine chemical materials and powder products.
Feed Industry
Feed additives and granular feed materials.
Other Suitable Materials
Extruded granules, wet mixed granules, large particles, small blocks, sticky granular materials and materials with volume change during drying.
Working Principle
Purified-air heating, agitated fluidization and negative-pressure moisture removal.
The batch sequence combines conditioned airflow and mechanical stirring to maintain material movement and uniform drying.
Air Heating & Purification
Air is filtered and heated before the induced draft fan introduces it into the lower chamber.
Fluidization & Mixing
Hot air passes through the perforated distribution plate. Airflow, negative pressure and internal stirring establish fluidization and reduce agglomeration.
Moisture Removal
Hot air contacts the material directly, transfers heat and carries evaporated moisture through the exhaust route.
Product Discharge
Dried material leaves through the unloading system. Automatic feeding and discharge can be configured when required.
Key Features
Batch fluidization engineered for uniform drying and contained handling.
Actual drying time and performance depend on material properties, loading and operating conditions.
Efficient Fluidized Drying
Intensive contact between heated air and fluidized material supports rapid moisture evaporation and uniform drying.
Uniform Temperature Distribution
The combination of controlled airflow and mixing helps maintain consistent drying conditions throughout the batch.
Anti-Agglomeration Design
The stirring device helps prevent wet material from forming lumps and reduces channeling during drying.
GMP-Compatible Design
Enclosed negative-pressure operation, filtered airflow, hygienic construction and an easy-cleaning structure support GMP-oriented production.
Flexible Loading & Unloading
Tipping discharge supports fast, complete unloading; automatic loading and unloading can be configured.
Wide Fluidization Range
The system can process suitable materials with different particle sizes and moisture characteristics.
Short Drying Time
Typical drying time is 15–30 min, depending on materialutes, depending on material properties and process conditions.
Main System Components
Core equipment sections and their process functions.
The final component scope and automation level are confirmed according to production and cleaning requirements.
