There are many ways to obtain air and product property measurements. Once obtained, these measurements will reveal the efficiency of your drying process and allow you to make the necessary improvements.
Solids drying is a complex process of simultaneous heat and mass transfer.
The measurement and control of gas and solids properties is important for efficient operation. The majority of solid drying applications are convective in nature, involving heated air to transport heat to the product and remove evaporated water. Air and product property measurements can be part of a manual control or optimization plan. They also can be developed into a continuous control or optimization application by using online instrumentation. A common machinery configuration for solids drying in many industries is a conveyor dryer.
