~Introduction

Rotary vaccum dryers offer clean,simple and effective method of drying wet case,powder and even slurry.Labor and energy costs are minimal compared to tray dryers and product losses during handling are also negligible.Additionally valuable organic solvents can be conveniently condensed and recovered.

Working Principle

The drying in a rotary vacuum dryer is a batch operation under vacuum.It is possible to dry heat sensitive materials at well below boiling points of water and solvents.Drying time depends on materials being dried,amount of solvent or water to be removed,desired final moisture content,permissible jacket temperature etc.The dryer is available in sizes ranging from 100 liters to 20.000 liters gross volume.The volume of wet material loaded into the dryer is usually restricted to 40-45% of gross volume.

Features

• Valuable organic solvents can be conveniently condensed and recovered;

• Labor requirements is minimum and product losses during handling are negligible provided;

• The agitator is usually the hallow cylinders with hollow arms this allows a considerable increase in heating surface are these by reducing the drying time;

• Low temperature drying under vacuum makes them more suitable for heat sensitive materials to maintain the quality;

• The expensive solvents can be almost completely recover through a suitable Condenser&Vacuum Receiver;

• As a heating media we can used Thermatic Fluid,Steam or Hot water.When hot water is used for heating it can be electricaally heated when steam is not available;

• The rotary parts are slow in rotating that ranges from 5-15RPM.The drying done in a Rotary Vacuun Dryer is a form of batch operation;
