CFD Dryer
The CFD-type walking floor dryer is designed for drying biomass to a specific target moisture content.
The drying systems are intended for continuous operation.
The drying systems can be supplemented by the LiPRO conveying system and thus individualized e.g. by an extended sieve unit.


Compact drying system designed as a container unit with sieving function on the walking floor for fine particles and dust, suitable for drying wood chips and similar, developed for outdoor installation.
There is a filter system with replaceable filter mats on the air inlet side.
The heat supply, and thus the wood chips drying, is controlled by the temperature difference between the top and bottom of the drying material, measured by thermo-sensors. At the same time, the cycle times for the walking floor (material feed) and the discharge screws for the wood chips and the fine particles are set.
- high manufacturing quality
- statically laid out walking floor
- the almost wear-free walking floor is developed by a special company
- hot-dip galvanizing and powder coating of the dryer guarantee a long and safe use of the machine
- the hydraulic power unit is composed of industrial solutions designed by us for continuous use

Specification
