Indirect vs. Direct: The Heat Transfer Method Does Affect

Most applications employ steam as an indirect source, using either a heat exchanger to transfer heat to a gas carrier or a jacketed vessel or drum to heat a surface. It also is used as a direct heat source to achieve effective drying. The amount of energy that can be carried by steam is related to the pressure at which the steam is delivered.

How Do Indirect Heat Rotary Dryers Work?

Indirect Heat Dryers Custom Solutions; Process Advantages of Indirect Heat Dryers; Direct-Fired Dryers. Heat transfer is accomplished through conduction of the heat from the shell to the product and radiation of heat off the shell. The internal flighting inside the rotating drum is specially designed to gently roll the material being

Dryers Heat Exchange and Transfer, Inc.

A dryer is used for the evaporation of liquids from solids. Most types of dryers are indirectly heated with either an internal exchanger coil or an external heat transfer jacket. This allows the use of remote heating and cooling utilities such as water or oil to precisely control temperatures inside the dryer.

Common Dryer Problems and Easy Ways to Fix Them

Start by reading our article describing how a dryer works before tackling a problem head-on, and as always, unplug the dryer or turn the power off prior to starting any repairs. For many of the problems you could be facing, finding a solution may require the use of a Volt-Ohm (VOM) reader, which can be picked up at most hardware stores.

Indirect Drying vs. Direct Drying FEECO International Inc.

Conversely, indirect dryers do not utilize direct contact with process gas to dry the material. In fact, this is the precise advantage of an indirect rotary dryer for two reasons: It avoids the issue of fine materials becoming entrained in a process gas, which can be a problem when processing fine materials in a direct dryer.
