Cylindro Conical Dryer
The high performance of conical dryers, without the height limitation
Best state-of-the-art drying, customized
The cylindro-conical offers the best drying performance with less constraints.
The high customization possibilities allow to rely on a high efficiency multi-purpose drying equipment or on a fine-tuned vacuum drying unit for demanding batch processes.
Space-saving design
The cylindro-conical dryer keeps the features of conical shaped-dryer, in a more compact design.
On a 700L equipment (used volume), the cylindro-conical dryer typically saves 1300 mm in height, approximately 25% of height saving.
Customizable diameter/height ratio awwlos to adapt to all kind of space available in plant.
Central shaft agitation
The agitation is key to the performance of the drying and emptying performance of the equipment.
The cylindro-conical dryer relies on a customizable central shaft. This agitator geometry allows for high customization in the agitation and heating efficiency.
The system is engineered to handle critical phase transitions where products move from liquid or viscous paste to a uniform final solid. The central shaft agitator ensures continuous movement, efficient heat transfer and reliable performance across all phases of the process.
Key advantages
Adapted to all height constraints
Short drying times
Uniform heat distribution
Flexible batch size working from 15 to 80% of nominal volume
Best discharge
The Cylincro-conical design orginally developped by Bolz-Summix meets the needs for intensive, low-maintenance applications in Chemical or food industry:
- Flexibility of mixing elements design
- Compliant with high temperature applications up to 350°C
- No sealing in contact with product, no bottom bearing
- Massive vessel flanges
- Chopper available
- option for shock pressure resistant design
- 15 to 15 000 litres effective volume
Pharmaceutical drying processes require high cleanability, no cross-contamination designs, as the original condry equipment design by Comber:
- Excellent discharge thanks to narrow agitator-wall tolerances, even more with machined surfacing option
- Excellent drying with large heated agitator surface
- No bolts, no couplings in the product area for cGMP compliance
- Openable vessel design option for inspection and cleaning
- From 25 to 15 000 liters
Final control before pack-off
After upstream particle formation or drying technologies, such as spray drying, some API and HPAPI powders still require a final vacuum drying step before pack-off.
At this stage, the product is close to its final specification. The key requirement is not only to reach the target residual moisture level, but also to secure the last critical control point before final handling.
For pharmaceutical applications, the dryer can be equipped with a swivable-bottom option. The cone is lowered and guided into a parking position, giving direct access to the vessel internals for visual inspection and cleanliness checks after each batch.
Key benefits of the swivable bottom
- Complementary final drying after spray drying or particle formation
- Direct access for inspection
- Suitable for high-value API and HPAPI powders
