The type KSP 22 condensation dryer is intended for drying all types of plant mass, especially that where the loss of essential oils during the drying process needs to be prevented. Traditional convection dryers accrue significant losses, even during methodical drying, which can be as high as 45% because heating the air, and with it the plant mass, increases air saturation, so fresh, unsaturated air needs to be supplied continuously, while the saturated, heated air is released into the atmosphere.
At temperatures over 30%, losses become significant due to oil volatility.
When it comes to condensation dryers, drying may be conducted at lower temperatures, from 20°C to 30°C, where fresh air is not added, but rather the same air is constantly recirculated.

Moisture condensation and extraction from the chamber is conducted by air passing through a capacitor.

In other words, during recirculation the air captures the moisture from the plant mass being dried and supplies it in the form of water in the capacitor.

The dryer is designed as both a trolley and floor dryer, i.e. the plant mass can be supplied through the perforated dryer floor or into shelves (frames with a permeable bottom) or one or more levels.

Supplying through the floor or one or more levels depends on the type of material, density and layer height.

This method of drying with the same air being recirculated and without adding fresh air leads to significant energy savings, but above all, it improves the quality of the final product. The benefits of the system are the quality of the product and energy savings, while the only drawback is longer drying times, i.e. a higher number of units of time is needed for the same dried plant mass. The drying time of the condensation dryer is 36 to 48 hours.
