Product Description

Flash Dryer

We offer Flash dryers in three type negative draft (negative pressure drying), positive draft (positive pressure conveying) and balance draft (positive-negative conveying).

Flash type or pneumatic dryer are used for removing surface or unbounded moisture from a feed. Technology behind it is relatively low residence time and moisture is flashed off, a consequential amount of evaporative cooling takes place allowing higher inlet temperature to be used without excessively heating the product.

We offer a complete flash dryer package including hot air generation system via steam or gas, feeding system, cyclones or air bags, wet or dry scrubber for capturing fines, product collection section, control & instrumentation. We also provide optional accessories like feed preconditioning depending upon application, product conveying cooling.

Falling Film Evaporator

A falling film evaporator is used in industries to concentrate liquid especially heat sensitive materials In this type of evaporators the liquid is feed from the top of the evaporator design of the product distribution system in the evaporator is such that the product wetting of the tubes should be full and evenly.

The product is distributed into the heating tubes in a form of thin layer and it flows downwards at boiling temperature and start evaporating.

The product and the vapors goes into the separator where the both is separated and vapors is forwarded to next effect. This type of evaporators can be operated with very low temperature differences between the heating media and the liquid. The effect of this type evaporator depends of the capacity and type of product. While designing number of effect is calculated considering steam economy and cost.
