Agitated vacuum pan dryer

Agitated Vacuum Pan Dryer

Turbodry® - series TD 0.8/1.1 - TD 40/60

The Turbodry® pan dryer has proven to be excellent for the drying of sensitive, pasty and other “difficult” products that pass through a highly viscous stage during the drying process. Excellent product discharge and shortest cycle times.

Designed for frequent product changes with excellent cleanability using CIP systems, simple validation. Suitable for use with microwaves for optimum drying performance. 

Ideally suited for the installation of isolator systems for contained discharge, sampling and heel removal.

Inerting

Prior to feeding slurry into the agitated Nutsche filter or filter dryer the vessel interior is inerted by a controlled displacement of the oxygen containing atmosphere with Nitrogen. This procedure prevents the potential formation of an explosive atmosphere in the vessel interior.

Filling

After inertization is completed wet filter cake from a centrifuge or Nutsche filter, or dependent upon the application slurry is fed into the dryer.

Drying

For efficient drying the dryer is typically evacuated in steps and heated up at the same time. During the drying process the product is agitated. The dryer is maintained under vacuum and at the maximum allowable temperature for the product until the final required product humidity level is reached.

Cooling

After drying is completed the product is cooled down prior to discharging.

Discharging

The dried and cooled product is discharged thru the side discharge valve. The product is transported to the discharge valve by the agitator.

Cleaning

Using spray balls a cleaning fluid is sprayed onto all product wetted internal surfaces for the internal cleaning of the equipment in between individual batches or for product change over. This provides for full and efficient cleaning of the dryer interior.

Technical data
