Drying technology

During the drying process, moisture mostly in the form of water is removed from the material to be dried.

Two things can be achieved with this procedure. First of all, thereby microorganisms such as fungi and bacteria can be deprived of their livelihood base and second the heat value can be increased. These two advantages are on the one hand used during storage of grain and oilseeds and on the other hand, during storage of heating material such as wood chips, firewood, or similar material. We can offer you different components for drying.


Heat exchanger

Compact unit for waste heat utilisation

The Heat exchanger is perfectly tailored to the utilisation of waste heat attained from biogas and combined heat power plants.

The completely individual combination of fan and heating coil enables us to meet all the demands of our customers. This has been especially compiled to allow a quick and easy air-heating for container-drying and storage ventilation drying.

At a flow temperature of 80° C and a return flow temperature of 65°C, the air temperatures shown in the table in °C obtain at an ambient temperature of 20°C at the output side of the Heat exchanger.

The control system is adjusted and fitted according to your plant.



The heat box is a complete heat exchanger unit for an outdoor installation. The different sizes are optimally adapted to the drying with waste heat.

At a flow temparature of 80°C and a return flow temparature of 65°C, the air temparatures shown in the table in C° obtain at an ambient temparature of 20°C at the output side of the Air-Heater.

Mixing conveyor

Our new Spiral Mixer – Grain Mix not only improves the homogeneity of a bulk material but also the drying process by circulating the grains in the storage. As a result, pressure losses can be reduced and uniform ventilation of the layers in the bed can be achieved.

With a maximum traverse length of 12m, it is also possible to use it to homogenize even large storage cells. A simple control with an adjustable limit switch also guarantees variable use. The Spiral Mixer is also suitable for all grains and is recommended in conjunction with an aeration floor.

  • Combination option of Spiral Mixer with full-surface aeration floor
  • Homogenization of large storage cells
  • Reduction of pressure losses
  • More efficient ventilation and drying
  • Suitable for all grains
  • Variable application through simple control with adjustable limit switch





Box for ventilation and drying of grain and seed.


  • ventilatation and drying with low pressure loss
  • storage of grain and seed
  • ideal for small and minimum quantities
  • 2 boxes stackable on top of each other at simultaneous ventilation
  • perforation inside the hopper 1,5mm
  • also suitable for rape
  • transportation with a forklift
  • made of galavanized sheet steel

hay bale drying system

With the new hay bale drying system, the production of hay in the form of round bales of high quality is guaranteed. The technical ventilation ensures shorter drying times, which improves the forage quality.

The hay bale drying system can still be expanded in a modular way, which is why it can be optimally used by both small farmers and large farms. The compact design also ensures high stability and easy operation and assembly.

  • Obtaining high quality hay
  • Greater cleanliness and hygiene
  • High flexibility through modular design
  • Corrosion and weather resistance
  • High stability through the use of galvanized steel sheet
  • Compact construction

full surface aeration floor

Storage hygiene is a very essential topic. This is why aeration floors have been used for decades. The attachment is usually on a substructure made of wood and screwed and uncoated steel sheets. However, this can result in the formation of mold and oxidation residues, which in turn attract insects or other pests.

In addition to good weather and corrosion resistance, our newly developed, full-surface aeration floors also have a smooth surface, which makes surface cleaning easy. Special cleaning flaps even make it possible to clean the floor or the interior space. However, the greatest advantage of the new full-surface aeration floor is that they can be driven over, for example with a wheel loader.

  • Corrosion and weather resistance
  • Easy cleaning due to smooth surfaces
  • Floor and interior cleaning by cleaning flaps
  • Greater cleanliness and hygiene
  • Higher stability and trafficability (e.g. with wheel loader)
  • Full-surface and variable ventilation from fine seeds to coarse wood chips
  • Efficient ventilation through minimal opening cross-section
  • Specific adaptation of the opening area to the material to be dried
  • Very high air volumes for drying possible
  • Material made of galvanized steel or stainless steel sheets
