Drying principle

Hot air is blown through a double floor – a grate floor – through the product to be dried. A moving paddle system mixes and conveys the product throughout the drying time. This simple principle guarantees virtually maintenance-free and fault-free drying.
The paddle wheel is moved across the dryer by the running gear several times throughout the drying process. The change of direction is controlled by limit switches and the corresponding automatic control system.
This combination ensures optimal mixing of the goods and thus consistent and homogeneous drying. The risk of clumping is avoided with this system, even if the goods are heavily contaminated or extremely damp.
The feed-and-turn dryer is the ideal application for small and medium-sized quantities of drying material. Two different operating modes are available: batch drying and continuous drying.
With small quantities, batch drying is selected, i.e. the dryer is filled and the drying programme is then started.
Once the dryness level required has been reached, cooling can be carried out if necessary, and emptying follows automatically.

stela has developed a special feed-and-turn mechanism, by means of which green plants, herbs, grasses, pellets, granulates, wood chips, pomace and many similar products can be dried. In the middle power range of around 2,000 kW, the feed-and-turn dryer with its new turning mechanism is an outstanding alternative to a belt dryer.
