Dryers/dehydrators: Rotating dryer

An energy efficient, robust, rotary dryer.

The Rotary Dryer is used for the drying of loose, bulk products of varying size: organic materials such as crushed olives, alfalfa, chopped bread, seeds, grains, etc, or minerals such as various chemical products, sludge and slurry cake, etc.

The internal cellular structure ensures that the product is uniformly distributed. This not only increases the surface area of the product but also balances the cylinder, which consequently reduces the input of power needed to operate the process.

The heat flow can be air heated by an electric heater, by a mixture of air and combustion gases produced by a hot air generator or, when possible, by steam generator or co-generation, this according to the product to be treated. A wide variety of fuels can be burnt including diesel, fuel oil, or even by-products such as wood offcuts, sawdust, olive cake, shells and husks, etc.
