AgroDry® Grain dryers with circulating air system

You would like to dry grain gently and homogeneously for storage, processing or transport? AgroDry® grain dryers with circulating air system from STELA offer a suitable solution for various types and quantities.

Our grain dryers can be designed in many different ways. This system for dryer volumes from about 44 m³ allows energy savings of approximately 20% compared to pure exhaust air systems by its active heat recovery. In contrast to exhaust air systems with passive heat recovery, circulating air systems have an additional circulating air fan that actively mixes the cool air with the warm air - as well as non-saturated exhaust air from the drying area.

                                                                                  

STELA grain dryers dry evenly

AgroDry® grain dryers with a circulating air system are modular in design and can be implemented in all capacities from approx. 4.5 t/h upwards. The basic functionality always remains quite similar: a free-flowing drying product, for example different types of grain, is conveyed into a storage bunker. From there, the drying product passes through the drying system from top to bottom by gravity only.

Roof-shaped channels are installed horizontally to the direction of fall. They have three functions: The staggered roofs continuously mix the drying product on its way down. The roofs are open at the bottom and lead alternately - depending on their function as warm or exhaust air ducts - into the neighboring warm or exhaust air channel. These cavities allow the air to pass through the drying material everywhere in the grain flow, which enables a homogeneous drying result.

The drying tower thus consists of the drying column and two air ducts: a warm air side, which ends in the roofs open to the warm air side, and an exhaust air side. The moisture from the grain flow inside is conducted through the roofs, which are open to the exhaust air side, into the exhaust air channel.

Custom grain dryers

Optionally direct and indirect firing via burners or air heaters can be used for air heating. Depending on the locally available resources, conventional energy sources such as heating oil or gas as well as superheated steam or hot water from existing combined heat and power (CHP) systems can be used for heating. Alternative energy sources such as biogas or biomass from grain straw or wood chips can also be used as climate-neutral heating methods. And of course, a combination of different energy sources is also possible (STELA AgroDry® Hybrid).

All STELA grain dryers are also adapted to the respective conditions and requirements regarding dust and noise emissions.

The dry product is removed continuously from below via a discharge hopper using appropriate conveyors. The pneumatic discharge system also provides a constantly even discharge moisture due to the variable control of the discharge interval.
