The technologically prepared drying materials are spread in equivalent layer with a thickness of 2-3 centimetres, on endless bend, on three levels.

The circulating of the warm air firstly does the warming, then earn- away the moisture of the material that is drying.

In a case of increased humidity, part of the air with overpressure is pressed out of the dryer, and the same quantity of dry air is absorbed in through the chamber.
The complete regulating of the given temperature and the air moisture are regulated and controlled with electronic watering process of the defined drying regime.

Technical characteristics of the dryer:

- The drying is indirect, with warm air;
- The daily capacity is 1000 kg dried vegetables, per on bend (The drying process is 6 hours);
- The role of the ventilator is equal mixing of the air in the tunnel and releasing the steam;
- The work of the electromotor and the ventilator is time-programmed;
- Two crossly set thermometers control the temperature in the tunnel;
- The tunnel of the dryer enables maximal technical isolation;
