  • How Do Indirect Heat Rotary Dryers Work?

    Indirect Heat Dryers How Indirect Heat Dryers Work; 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 processed, constantly exposing new material to the heatedIndirect dryers rely on the heat emanating from the drum’s shell to dry the material via conduction and radiation Subsequently, indirect dryers would not benefit from the addition of lifting flights, since there is no process gas moving through the drumIndirect Drying vs Direct Drying FEECO International IncIn the last 25 years, a more efficient and cost effective method has been introduced, using indirect heat transfer to heat free flowing bulk solids A series of vertically stacked modules filled with hollow, stainless steel plates comprise an indirect heat exchanger This unit uses a countercurrent flow of heating water or fluid runningDirect vs indirect heating technology Solex

  • 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 deliveredSystems that primarily use conduction for heat transfer are referred to as “indirect” dryers With indirect dryers, solid metal walls separate the wet cake from the heat transfer medium (such as steam, hot water, or oil) Thermal energy is transferred from the heat transfer medium into the metal wall and then from the metalThermal Drying of Wastewater Solids
