types of industrial dryers heat echange and transfer

Process dryers fall into two main types direct and indirect. Direct dryers convectively heat a product through direct contact with the drying medium. Indirect dryers conductively transfer drying heat to the product to be dried through contact with a heated wall, pipe, belt, etc. Industries Using Process Dryers.

Nov 09, 2011018332based on the dryers steam and temperature measurements. Basis for this calculation is that the heat transfer coefficient, U, is a function of the average moisture of the product in contact with the surface. Assume the products solid specific heat value is constant, for water is 1.0. This resulting mixture heat transfer should be.

Membrane type air Dryer. Refrigerated type air dryer- Refrigerated type air dryer is most popular and common for general purpose application.The compressed air is cooled in an air-to-refrigerant heat exchanger to about 4 Deg C, at this temperature moisture in air get condense and drained though moisture separator.

The shape and angle of the shovels ensure optimal heat exchange between product and side wall. Separately driven choppers dissolve lumps, thus resulting in a fine-grained to powdered material consistency. Benefits include very short drying times, which can be further reduced by including a vacuum dryer in the design.
