Arrowhead Seperation Engineering Pvt. Ltd.

Wet feed is charged as a batch and is subjected to indirect heating while undergoing agitation due to the action of tumbling. The operation is normally carried out in vacuum. Recovery of solvent is possible by condensing the vapours generated during the drying operation.

Features:

1. Granular wet materials can be handled.
2. Low temperature operation is possible.
3. Solvent recovery can be carried out.
4. System is batch.
5. High energy efficient.
6. Mode of heating is indirect.
7. Conduction drying.
8. Closed operation.

Typical Applications:

1. Pharmaceuticals.
2. Crystalline Materials.
3. Insecticides.
4. Pesticides.

The system consists of Vacuum Double Drum Dryer, Condenser, Receiver, Feed Vessel with Valve, Accessories, Skid etc. The Double Drum Dryer except the drive is enclosed in a suitable cylindrical enclosure having quick opening doors at both the ends. The enclosure is jacketed, to which low pressure steam is supplied. This ensures that there is no condensation of vapour generated during the drying operation, on the walls of the enclosure. The drive to the double drum dryer is fixed outside the enclosure. The vapours escaping from the dryer enclosure are condensed in a suitable shell and tube type condenser and collected in a suitable receiver. Material is fed to the drum dryer because of vacuum suction. The valve provides requisite control.

Features:

1. Suitable for handling liquid or pasty feeds.
2. Suitable for materials required low temperature drying.
3. Product is in the form of powder.
4. Uniform drying due to uniform application of film. Medium/high range capacities.
5. Very high thermal efficiency.
6. Continuous operation.
7. Compact installation.
8. Heat sensitive material can be dried.
9. Heating medium can be either low pressure steam or hot water.
10. Solution containing solvents can be dried with complete recovery of solvent in continuous manner.
11. Totally enclosed machine and no exposure to the atmosphere.

Typical Applications:

1. Heat Sensitive Materials.
