Spray Belt Dryer

Description

The TAG spray-belt dryer (SBS) combines the spray drying and the belt drying principles within one system. The pulverized product, which has relatively high residual moisture, drops onto the belt integrated inside the dryer, where it forms a bed up to several centimetres high. The belt conveys the product from the primary drying zone to an agglomeration zone, and from there to zones for secondary drying and cooling. The drying and cooling air is sucked through the product layer and the belt and is removed underneath the belt.

Application

The spray-belt system has been developed specifically for highly viscid, thermoplastic, hygroscopic, temperature-sensitive products that have to undergo a liquid-to-solid transition process. The system also lends itself ideally for highly oily and fatty products.

Advantages

	Production of agglomerated, low-dust powders with instant properties
	Controlled modification of particle properties
	Secondary drying and cooling in conditioned air
	Low outgoing-air temperature; low product temperature
	Controlled addition of powder to assist agglomeration
	Liquid gas may be used to encourage the formation of particles
	High automation level
	CIP cleaning
	Pilot dryer available for drying tests in our own experimental facility
