Dryer

Schaaf uses special short-wave and medium-wave infrared emitters for the thermal post-treatment of the products, which, in contrast to conventional hot-air drying processes, operate with a very high degree of efficiency.

The infrared drying process does not require the heating of dry air, the extrudate is heated directly by the infrared radiation. The heat flow within the product carries the moisture to the outside, where it is extracted by the air flow of the built-in room air blower.

The stepless control of the heat emission allows the energy flow to be precisely determined, from gentle drying to browning roasting.

The roasting drum runs on special, low-noise carrier rollers and is made of corrosion-resistant materials. The special drum profile guarantees a gentle circulation of the product and ensures a uniform drying result.

The continuously adjustable drum speed and a discharge device that can be adapted to the products enable the filling level in the drum to be regulated.


Dryer with PTFE coating

In order to dry the sweet slurries applied to breakfast cereals, the inner drum surface of the post-drier is coated with a PTFE film to prevent the sticky product from sticking to the drum surface. This ensures particularly hygienic and gentle drying of the product.

Combination drying / application drum

As an alternative to single drum systems, in which the products are conveyed into the downstream drum via belt or vibration conveyor systems, Schaaf offers space-saving drum systems in which the drying and application drums are arranged one above the other. The product is gently transferred via a hopper from the dryer to the application drum positioned below. There is no need for a separate transfer device.
