For products which need a very high standard quality level, a different version of the horizontal paddle dryer (Fig. 6) has been designed. The construction differences can be summarized as follows:

- The shaft is supported on only one side to allow the opening of the opposite head for cleaning and inspection

- The design of the paddles provides for self-cleaning of the cylindrical body and heads

- All surfaces are consistent with GMP norms

- The sealing system is a special double mechanical seal with flushing system

- All surfaces in contact with the product are mirror polished.

The geometrical volume ranges from a few liters to approximately 5000 liters (Table 5).

Vacuum Shelf Dryer. It is the simplest and oldest vacuum dryer known. It can be used for drying a wide range of materials like solids, free flowing powders, fibrous solids having special forms and shape, practically any material that can be contained in a tray. It finds application where the material is sensitive to heat and so valuable that labor costs are insignificant. At the same time, it is normally used when the powder production is very low.
