Vane dryers / granulators
Paddle dryer/cooler is a high-speed horizontal dryer, consisting of a casing, two rotating in opposite directions hollow shafts with special paddles and a gas-tight cover.
Blade technology based on conductive drying method of drying (using a coolant, for example oil). During conductive drying, the heat transfer between the coolant and the product occurs through the metal surface. Optimal heat transfer is guaranteed, if the product is in constant contact with the heated surface and is constantly updated. Thanks to a special wedge-shaped form of the blades, which are mounted on the shafts of the dryer, the product is optimally mixed, which further increases the heat transfer coefficient, and is moved further along the dryer.
The shafts are designed so that the blades provide an intensive heat exchange. This achieves high heat transfer coefficient and increase in heat output of the dryer.
Paddle dryers provide high intensity and efficiency of drying and may be used for the treatment of a number of materials, from solids to high-moisture slurries or paste-like mixtures, including those sensitive to high temperature.
