The Multi-Belt dryer is a continuous convection process. The product to be dried is layered evenly on a conveyor system that transports the product through the dryer housing while being exposed to hot air. Multi-Belt dryers redeploy the product several times throughout the drying process onto new belt systems to optimize the removal of the desired moisture and produce uniform product quality. The main advantage of the BINDER’s Multi-Belt dryer is the large drying surface created in relation to the small footprint of the extremely efficient machinery. Especially in the food industry, shorter run times at low drying temperatures and bed heights can be realized.
For the process shown below, a large amount of water needed to be evaporated; therefore, a pre-dryer is being used in conjunction with the Multi-Belt dryer to achieve optimal results.
