Testing provides unparalleled information when designing a rotary dryer and can allow experts to work out process variables to help define the recipe for successful drying.
The reasons to engage in rotary dryer testing include:
To Test Pre-Conditioning. Material is often dried prior to further processing, because many processes require a material feedstock within a specific moisture range. Testing the material during the pre-conditioning stage can determine what drying parameters are required to reach the target moisture range.
To Confirm End Product Characteristics. Specific characteristics are often desired in an end-product. Testing can ensure that characteristics such as crush strength, or moisture content are met, and define the variables necessary to reach those parameters.
To Optimize an Existing Process. Testing different variables, such as adding in a back-mixing process prior to the dryer, or testing a recycle loop, allows one to define the parameters necessary to improve their process.
To Design a New Process. Dryer tests are valuable when looking to design a new industrial drying system, and especially valuable when working with new processes or materials. Testing can help work out process variables and ultimately offer a recipe for process scale-up in the design of the dryer.
