Accurate dryer scaleup with help from your supplier
Maybe you've been in this situation: The powder or granule you developed in a lab-scale or pilot-plant dryer just doesn't come out right in a productionscale unit. A poor or inadequate scaleup technique is typically the problem. This article gives you an idea of what's involved in working with the dryer supplier to accurately scale up test results from lab-scale or pilot-plant dryer to predict the drying cycle in a production-scale unit. The information here uses the example of a mechanical fluidized-bed mixer-dryer to show how drying test results can be scaled up.
Drying is an energy-intensive process. When you scale up from lab-scale dryer tests to predict your material's drying time in a production-scale dryer, accurate calculations are critical. The more accurate your calculations, the more likely your drying process will be as energy- and cost-efficient as possible.
