Technical Specifications
Technical specifications
Listed values apply to the identified configuration. Confirm material conditions, utilities and optional equipment before selection.
| Model | Reference Drying Capacity (kg/h) | Fan Power (kW) | Fan Pressure (Pa) | Air Volume (m³/h) | Inlet Air Temp. (°C) | Feeding Method |
|---|---|---|---|---|---|---|
| Model 1 | 10–15 | 7.5 | 5.5×10³ | 1500 | 60–200 | Star feeder / Pneumatic conveying |
| Model 2 | 20–25 | 11 | 5.8×10³ | 2000 | 60–200 | Star feeder / Pneumatic conveying |
| Model 3 | 30–40 | 15 | 7.1×10³ | 3850 | 60–200 | Star feeder / Pneumatic conveying |
| Model 4 | 50–80 | 30 | 8.5×10³ | 7000 | 60–200 | Star feeder / Pneumatic conveying |
The capacities are reference test values for sour-plum crystals at 20% initial moisture, 5% final moisture and 130°C inlet air. These values are not guaranteed sodium gluconate throughput. Actual capacity depends on the feed and operating conditions and requires a separate material test.
Model-specific capacity, inlet temperature, fan power, dimensions and utility consumption must be confirmed against the material and final equipment configuration.
Applications
Typical industries and materials for fluidized-bed drying.
Confirm material properties and process conditions before selecting the equipment configuration.
Typical Materials
Pharmaceutical raw materials, tablet granules, traditional Chinese medicine granules, health-food granules, beverage powders, corn germ, animal feed, plastic resins, citric acid and other suitable granular or powder materials.
Sodium Gluconate Drying Application
The horizontal fluid bed dryer can be evaluated for sodium gluconate drying as a material application of the equipment family. Selection depends on feed moisture, target final moisture, particle size, fluidization behavior and the inlet-air temperature suitable for the material.
Actual throughput depends on the incoming feed and operating conditions. A pilot or material test is recommended to confirm stable fluidization, drying performance and final product quality before sizing the equipment. The sour-plum crystal reference capacities in the model table are not a sodium gluconate production guarantee.

Working Principle
Fluidization, moisture removal and controlled discharge.
Clean heated air enters through the bottom distributor. Upward airflow suspends the material, promotes heat and mass transfer and maintains the dryer under normally negative pressure.
Material Feeding
Wet material is introduced continuously or intermittently according to the selected operating mode.
Air Distribution
Filtered heated air is distributed uniformly through the lower air-distribution section.
Fluidization
Upward airflow suspends the particles and maintains the material in a fluidized state.
Heat & Mass Transfer
Intensive air-to-material contact supports rapid transfer of heat and moisture.
Moisture Removal
For continuous operation, material remains in the drying zone for seconds to several minutes, depending on process conditions.
Product Discharge
Dried material is discharged automatically from the opposite end of the horizontal bed.
Dust Separation
Entrained fines pass through the selected cyclone, bag filter or combined collection system.
Induced Draft & Exhaust
The centrifugal fan maintains airflow and negative pressure before the cleaned exhaust air is discharged.
Key Features
Process flexibility for granular and selected powder materials.
Final performance depends on material properties, operating mode and the selected air, feeding and dust-collection configuration.
Efficient Fluidized Drying
Intensive contact between heated air and fluidized material promotes efficient heat and mass transfer.
Continuous or Batch Operation
The system can be configured for continuous or batch processing according to production requirements.
Short Drying Time
In continuous operation, material can pass through the drying zone within seconds to several minutes, depending on material and process conditions.
Flexible Dust Collection
Cyclone separation, bag filtration or a combination can be selected according to particle size, bulk density and dust characteristics.
Negative-Pressure Operation
Normal negative-pressure operation supports controlled airflow and dust management.
Flexible Feeding
The feeding arrangement can be adapted to material properties and production requirements.
Flexible Heat Source
Steam, electricity or a hot-air furnace can be configured according to project requirements.
System Configuration
Main system sections and their process functions.
Cyclone separation and bag filtration are selected according to material density, particle size and dust-loading conditions; neither is automatically treated as standard for every project.
