The single-pass rotary drum drying system is mostly used for drying products with low moisture content or raw materials such as 3-phase pomace that can be dried at high temperatures. Thanks to the carrier sides in the single-pass drying drum, the drying surface area is increased and effective drying is achieved.

This drying system, consisting of 2 different interlocking drums, is used in sawdust, animal manure and pomace drying systems.

The three-pass drying drum is used in drying light raw materials such as sawdust and also in drying high-humidity raw materials such as 2-phase pomace. This system, which consists of 3 interlocking drums, is the most efficient among rotary drum drying systems.
