Illustrated is a Vertical Blender combined with the ancilliary items mentioned above. All Ross Mixers and Blenders are available with complete vacuum and control systems.
Vacuum Drying Flow Chart
Once vacuum is applied, low vapor pressure, gentle heat and slow agitation quickly force moisture from the bulk material. The vapor passes through a filter and condenser, then is transferred to a receiver. The vessel is jacketed to control internal heat.
