Visualization and control of food drying processes at the MAPES company plant

The Mapes company specializes in production and sale of dry dog food. The company was founded in 1990 and began production of feed in its original plant. In 1993, a new building was built and all production and production technology for drying were moved there. Today, Mapes is among the top producers and sellers of quality dry food. Their products are preferred not only by Czech breeders, but also internationally, where the company distributes a wide selection of its products.

Control system

The control system of air-conditioning provided for the food drying process at MAPES consists of an operator PC fitted with the Reliance 3 visualization software.

The control processor directs four valves with Belimo actuators, four fans, and six Sahara coil heaters. Drying is performed in two chambers. The control system handles automatic operation of drying, control of sterilizing and maintenance cycles with temperature control in the drying chambers and humidity control in the final stage chamber. The processor also handles automatic renewal of system states in the event of power failure, without operator intervention.

The Reliance 3 visualization system serves for controlling individual armatures in manual mode, setting drying parameters, saving system values, and creating protocols for each drying cycle.
