Applications
Loose materials suitable for continuous internal-heating fluid-bed drying.
Applications include loose materials suitable for continuous internal-heating fluid-bed drying across chemical, pharmaceutical, food and environmental applications. Confirm material properties and process conditions before selecting the equipment configuration.
Pharmaceutical Industry
Antibiotic materials, pharmaceutical granules, traditional Chinese medicine extracts and enzyme preparations.
Food Industry
Sugar, monosodium glutamate, salt, soy protein, starch, feed additives, and fruit or vegetable granules.
Environmental Applications
Sludge granules and biomass particles where the material and process conditions permit fluidized drying.
Suitable Material Forms
Granular, powder, crystalline and fibrous materials.
Working Principle
Internal heat transfer combined with fluidization and moisture removal.
Internal exchangers add a conductive heat-transfer path inside the material layer, while fluidizing air maintains movement and carries evaporated moisture from the dryer.
Fluidization & Preheating
Heated air enters the lower chamber and passes through the distribution plate, bringing the wet material into a continuously moving fluidized state.
Internal Heat Transfer
A heat-transfer medium circulates through immersed tubular exchangers and transfers heat to the surrounding material. The medium and utility conditions require confirmation for the selected configuration.
Convective Drying
Fluidizing air supplies supplementary heat and removes moisture. Internal heating allows the required air volume to be reduced.
Discharge & Exhaust Treatment
Dried material is discharged continuously after reaching the target moisture, while moist exhaust air passes through the selected dust-separation system.
Key Advantages
Process benefits of internal heating within the fluidized material layer.
Actual performance depends on material characteristics, heating conditions, airflow and the selected equipment configuration.
Energy-Efficient Drying
Direct heat transfer inside the material layer reduces dependence on large volumes of hot air and supports higher thermal utilization.
Reduced Air Consumption
Lower drying-air demand can reduce fan power and the load on downstream exhaust-treatment equipment.
Uniform Product Conditions
Controlled internal heating helps maintain stable material temperature and reduce local overheating dryer.
High Drying Intensity
Combined internal heat transfer and fluidization provide intensive heat and mass transfer within a compact processing section.
Flexible Process Control
Heating-medium temperature and flow, fluidizing airflow and material residence time can be adjusted around the drying duty.
Compact, Configurable Structure
The internal exchanger and its contact material can be selected according to capacity, material characteristics and corrosion requirements.
Lower Exhaust Load
Reduced exhaust airflow can decrease discharged heat loss and dust-treatment demand.
