Versatile Veneer Production
We offer everything from individual dryer plants with manual feeders, to complete veneer drying lines with automatic feeders, scanners and stacking systems. We supply the wood manufacturing sector with state-of-the-art technology for veneer drying, including the highest possible energy efficiency.
Decorative veneers are sliced and dried in Grenzebach plants all over the world. These veneers are used in the furniture sector, on yachts, in hotels, and for other interior design purposes. Peeled veneers dried on our drying lines are used to make plywood and LVL (laminated veneer lumber).

Babcock BSH merged with Grenzebach
In 2002 we acquired Babcock BSH in Bad Hersfeld, Germany. Today Grenzebach bundles worldwide the competencies and state-of-the-art technologies for the building materials sectors.
Veneer Drying Technology for Peeled Veneers & Decorative Veneers
Equipment & Highlights
Automatic infeed system with up to 23 cycles/min
Overlapping of the veneer sheets at the infeed to optimize the track load and taking into account the shrinkage of the veneer during drying.
Improved air distribution
Flow-optimized air distribution zones and a better balanced air volume over all decks for best, uniform drying results. The result is a higher drying capacity at lower energy consumption, and a high quality final product.
Modular design
Each modular dryer section is 2.25 m long. These modules are combined to obtain the required dryer length. Four, six or eight deck dryers with a working width of 4 m, 4.8 m, 5 m, 5.8 m and 6.2 m are available.
Special door design
Each aluminized access door extends over an entire section. It can be opened with one hand and features a special door hinge design. Soft bends instead of sharp 90° corners ensure a long lasting and perfect sealing effect.
Sine wave system
The special sine-wave guiding system between carry and cover belt helps to reduce the waviness in particularly wet and difficult to dry veneer species.
Consistent drying
The optimized nozzle boxes with saw tooth tread design guarantee a homogenous distribution of the drying air over the entire width and prevent damage to the veneer sheets.
Improved seal section
End-seal section at the wet end to prevent condensation and carbonization of wood pitch on the dryer walls.
Insulated dryer floor
Insulated floor for highest energy efficiency. No need for special foundations.
Improved end-seal system
End-seal at the dry end to prevent condensation and carbonization of wood pitch on the dryer walls.

Your Benefits at a Glance
Pioneering Technology
Optimized drying process with flow-optimized air distribution and balanced airflow across all decks for more uniform drying results.
Durability
Aluminized sheet metal construction for the entire dryer skin, providing corrosion resistance and long-lasting durability.
Efficient Access
Floating skin-type doors with a special hinge design, easily opened with one hand, featuring durable, flexible stainless steel seals covered with Kevlar®-reinforced fabric.
Superior Insulation
Thick insulation and advanced sealing systems minimize heat loss and ensure rapid, uniform heat-up.
Advanced Airlock Systems
Airlock systems and fresh air preheating devices prevent condensation and resinification, maintaining optimal conditions within the dryer.
Modular Flexibility
Dryer sections are 2.25 m long, allowing for customizable dryer lengths, available in four, six, or eight-deck configurations with various working widths.
Reliability & Quality
Grenzebach’s new generation roller track dryers offer exceptional reliability, minimized downtime, low energy consumption, and superior final product quality. Our partner company Millennium is serving the right solution for your needs on programming and controls.

Sine-wave guiding system in the veneer dryer
The unique sine-wave guiding system reduces the waviness of the veneers even when drying wood species with an extremely high moisture content, making handling and processing of the plywood veneers better and easier. The carry and cover belts and the special sine-wave system ensure that the moist veneer sheets, which tend to become wavy, are dried smooth and flat. Belt dryers without sine-wave guiding systems sometimes face the problem of so-called "omega" dry veneers, i.e. deformed sheets that obstruct the run of the sheets and clog up the dryer. Such sheets are not suitable for further processing into plywood or LVL. In the sine-wave belt dryer there are no such stoppages, and waste can be minimized. Not least thanks to the high availability of the system, this also results in a better utilization in downstream production stages.
“We have opted for Grenzebach because their team has a lot of experience in veneer drying. Grenzebach's know-how and service have assisted us with our innovation process. Of course, a number of trial runs were necessary before the optimum was reached, but then drying 3.55 mm beech veneer is not something that can easily be mastered.”
