Double-Cone Rotary Dynamic Vacuum Dryer vs. Round Static Vacuum Dryer:
A Comparative Analysis of Pros and Cons
VS
I. Structure and Working Principles
1. Circular Static Vacuum Dryer
- Structure: A circular sealed vessel where materials rest statically on trays or racks.
- Working Principle: Drying is achieved through external heating (e.g., jacket heating) and vacuum pumping to lower the boiling point of water. Materials remain stationary during the process.
2. Double Cone Rotary Vacuum Dryer
- Structure: A sealed vessel composed of two conical sections joined at the center, rotating around a horizontal axis.
- Working Principle: Materials are continuously tumbled and mixed during rotation, while jacket heating and vacuum pumping facilitate drying.
II. Key Differences, Advantages, and Disadvantages
1. Circular Static Vacuum Dryer
Advantages:
- Simple structure, easy to clean.
- Ideal for fragile, irregularly shaped, or shape-sensitive materials (e.g., tablets, 块状物料).
- No mechanical agitation ensures minimal abrasion, suitable for high-purity materials.
Disadvantages:
- Uneven heating due to material stacking, resulting in lower efficiency and longer drying times.
- Not suitable for high-viscosity or caking-prone materials.
2. Double Cone Rotary Vacuum Dryer
Advantages:
- Uniform heating and large surface area exposure through rotation, enabling faster drying.
- Effective for high-viscosity, pasty, powdery, or caking-prone materials (tumbling breaks clumps).
- Airtight design minimizes material loss, ideal for oxidizable or valuable substances.
Disadvantages:
- Potential damage to fragile materials (e.g., crystals) due to rotation.
- Larger footprint and higher space requirements.
III. Application Scenarios
- Circular Static Dryer: Best suited for stable, non-caking materials or low-volume, cost-sensitive production.
- Double Cone Rotary Dryer: Optimal for high-efficiency drying of viscous or caking-prone materials, particularly in batch processing.
