Vacuum Drying Systems
Member of Process Equipment Manufacturers Association
The Rota-Cone Vacuum Drying System will accomplish the following:
- Gentle tumbling and blending to continually cause wet material to contact the heated walls and to promote easy escape of vapors from the batch under vacuum
- Vapor condensation to accomplish solvent recovery
Similar engineered Drying Systems are applied to Horizontal Rotary Vacuum Drying Systems
Custom-designed PACKAGED DRYING SYSTEMS can include:
- Heated vessel in combination with vacuum atmosphere to ensure vaporizaion of moisture and drying of product.
- Stainless Steel or Nickel Alloy vessels
- ASME code pressure vessels and jackets
- Vacuum systems and solvent recovery
- Heating systems with temperature control
- Integrated controls with PLC-based process control
- Sanitary construction
- Solids sampling
- Load cell systems integration
- Liquid addition if required
- Computerized process control
- Data acquisition hardware and programming
- Vessel positioning system
- Dust tight extension sleeves
- Drum loading and discharging mechanisms
- Extended Warranty
Heating Systems
All Paul O. Abbé vacuum dryers can be heated by a variety of methods. These include steam, hot water or fluids.
Packaged heating systems based on any of these fluids can be supplied for any size or type of dryer. They are normally complete with all controls and can be skid-mounted or free-standing as required.
Vacuum and Solvent RecoveryVacuum dryers can be used with a wide array of vacuum systems. These are usually based on liquid ring pumps (water, oil or solvent sealed), or, in some cases, rotary vane pumps, rotary piston pumps or other vacuum sources.
Vacuum systems are available to operate from a few inches Hg to sub torr levels.
They can be built to the process requirement, with one or more precondensers, condensate receiver, transfer pump, seal fluid circulation and cooling pumps (liquid ring systems), separator tanks, aftercondensers and any level of instrumentation and control that is desired.
