| Other similar calcium salt solids | Crystalline solids after concentration and cooling | Water content similar to dihydrate calcium chloride |
Equipment Working Principle
The equipment operates on the principles of fluidized drying and air cooling, achieving material drying and temperature reduction through heat and mass exchange:
1. Drying Stage: Hot air is heated to 220°-240° and then introduced into the boiling fluidized bed, where it fluidizes the solid calcium tablets. The materials fully contact the high-temperature hot air, rapidly evaporating excess moisture. Precise temperature control ensures the final content stabilizes at 72-74%.
2. Cooling Stage: Dried materials enter the cooling bed, where ambient temperature air passes through the material layer, dissipating heat and reducing the material temperature to 50-60℃, preventing high temperatures from affecting subsequent packaging and storage.
Refined Working Procedures
| Step Number | Operation Process | Core Parameter Control |
|---|---|---|
| Step 1 | Raw Material Conveying | 68% content solid calcium tablets are uniformly fed into the boiling fluidized bed via a belt conveyor; conveying speed is adjusted based on processing capacity |
| Step 2 | Hot Air Drying | 220°-240° hot air is continuously supplied to the fluidized bed, maintaining stable material fluidization; drying time is dynamically adjusted according to initial material moisture content |
| Step 3 | Content Detection | Material content is monitored online. When it reaches 72-74%, the system automatically triggers material transfer to the cooling bed |
| Step 4 | Ambient Cooling | Ambient temperature air is supplied to the cooling bed at a constant velocity; materials are evenly distributed in the bed and cooled to 50-60℃ |
| Step 5 | Finished Product Conveying | Cooled materials are transferred to the packaging silo via a conveyor, awaiting subsequent packaging processes |

Frequently Asked Questions (FAQ)
What is the primary material input capacity range for this drying equipment?
The processing capacity is fully customizable based on production demands, typically ranging from 500kg/h to 5000kg/h.
What are the key drying and cooling temperatures managed by the system?
The high-temperature drying stage is strictly maintained at 220°-240° with a control accuracy of ±5℃. In the cooling stage, the post-cooling material temperature is brought down to 50-60℃.
How does the system ensure the finished product reaches the desired concentration?
The equipment uses real-time online content monitoring. When the material's solid calcium concentration stabilizes at 72-74% (with error margins ≤0.5%), the system automatically transfers the product to the cooling stage.
Can the system process materials other than dihydrate calcium chloride?
Yes. While primarily optimized for 68% content dihydrate calcium chloride solid tablets, it has high adaptability to process other crystalline calcium salt solids with similar water content.
How does the fluidized bed design contribute to energy efficiency?
The fluidized bed design ensures continuous, complete contact between hot air and the solid materials, boosting thermal exchange efficiency by more than 20% compared to traditional drying systems.
