How to reduce the energy consumption cost of spray dryer drying?

Drying can be one of the energy-consuming unit operations in your factory. Due to the high cost of crude oil, it is more important than ever to control the heat requirements of spray dryer drying operations. This column will discuss some ways you can do this.

Before deciding how to reduce the drying energy demand, you need to understand where the heat is during the drying process. The heat is input to the spray dryer through the heated inlet drying gas or through the heated wall of the dryer. Distribute the heat to the dried product, evaporate during the drying process and export the drying gas. Some heat is also dissipated through the dryer walls and components.
