Farmet offers a series of highly sophisticated stack cookers with an efficient heat transfer into the heated material, for the purposes of the technology of hot pressing. This equipment is designed for a high performance and work efficiency, uniformity of heat transfer as well as compact dimensions. Thanks to their simple design, the heaters do not require extensive service and maintenance.

The stack cookers are always equipped with a system of intelligent heat control, which precisely controls levels and the evenness of heating and temperature distribution in different layers of the cooker. For optimized humidity of the output material, the cooker is equipped with a material moistening procedure.

Thanks to the sophisticated regulation system, it is possible to monitor the temperature of the material as well as resting time, for which the material was exposed to a certain temperature. This positively affects the feed value of press cakes, namely the protein transformation. Optimization temperature and time exposure can make proteins less soluble in the rumen of ruminant animals (e.g. cattle), raising the content of by-pass proteins.

Technology Description

Stack-type cookers consist of several components: steam-heated floors, a drive, air suction, and regulation valves. The particular implementation depends on the required properties of the output material.

The material is supplied into the cooker via a screw conveyor. Inside the cooker, the material is gradually heated up as it falls through the several layers towards the discharge. Temperature as well the seed level at individual layers can be regulated. The cookers are equipped with a sophisticated system for the control of output humidity, which can be used to optimize the humidity by a precise dosing of steam into the cooker.

Technical Parameters

Stack cookers are offered at a range of performances and are always optimized for a particular technology.


The cooker can be supplemented with a range of various hoppers, conveyors, and other equipment. Yet the best solution is usually our turnkey delivery, which fulfils your requirements and guarantees a solution optimized from both the technical and economic perspectives, as well as comprehensive automatization.
