Roller Veneer Dryers
Roller dryers designed primarily for core and thicker veneer in a cut-before-dry process. Hot-air circulation promotes faster, more even drying and helps reduce moisture variation.
BG1334 Four-Deck Roller Veneer Dryer
BG1334 4-deck jetting roller veneer dryer consists conveying system, heating section, steam system, cooling section, exhausting system and input & output roller system. Heating section consists of two parts, front and back part, with heating fans set on both side to ensure consistent final moisture at each point.
In heating process, air is compressed into heaters by erect centrifugal fans for heating, and then compressed into jetting bellows. Afterwards, hot air is jetted onto veneers conveyed between rollers for drying. Hot damp air then again is drawed into centrifugal fans for a circular use. Part of hot damp air is exhausted through exhausting system in exchange of some fresh air to keep a proper air moisture. It adapt to the technologic conditions: first, cut; second, dry. It is mainly with drying core board of veneers. The stringy orientation of dry veneer is the same as inputting veneer, and the width should be more than 350mm, or it will be happened phenomenon of walling up veneers.
BG1333 Three-Deck Roller Veneer Dryer
BG1333 3-deck jetting roller veneer dryer consists conveying system, heating section, steam system, cooling section, exhausting system and input & output roller system. Heating section consists of two parts, front and back part, with heating fans set on both side to ensure consistent final moisture at each point.

BG1332 Two-Deck Roller Veneer Dryer
BG1332 2-deck jetting roller veneer dryer is a main equipment of producing veneer. It adapt to the technologic conditions: first, cut second, dry. It is mainly with drying core board of veneers. The stringy orientation of dry veneer is the same as inputting veneer, and the width should be more than 350mm, or it will be happened phenomenon of walling up veneers. There is a ventilator in every unit dry area; it adopts straight-conveying transverse - circulating jetting way, and it lets heat put into and make humidity (wet) vent, quicken the dry pace much. Also, it makes the veneer dry be well-proportioned, reduce warp of the hydrous rate. The product has some advantages: maintain convenience, trusty safe and so on. So this is a perfect product for drying thick veneers in producing veneers process.

How to choose the right dryer model?
The veneer type, veneer dimensions, thickness, initial moisture content, final moisture content, and daily production volume (calculated over 24 hours) are all taken into account.Generally, a mesh dryer is chosen for veneer thicknesses of 0.2mm to 1.5mm, and a roller dryer for 1.5-6mm.

Each one's pros and cons
The belt dryer is versatile; it can dry both thin and thick veneers. When dryers first came about, there were only belt dryers. Drum dryers were only gradually introduced from abroad and developed after 2000.
The only downside of a belt dryer is that the veneers aren't very flat after drying, especially those thicker than 1.5mm. So, except for pine, for other materials with veneers over 1.5mm thick, it's better to use a drum dryer. The veneers get pressed by the upper and lower rollers, and they come out flat!
But a roller dryer can't dry veneer thinner than 1.5mm, because the veneer is too thin and can slip through the gaps between the rollers, causing blockages! If the thickness is over 1.5mm, especially between 1.7mm and 6mm, roller dryers basically won't have any blockage issues. That's because our roller dryers and the spray box have a patented design. -
About choosing a type of dryer
Regarding choosing the type of dryer, if the customer's raw material wood is pine, then only a conveyor belt veneer dryer should be chosen because pine contains resin. After long working hours, the resin inside the veneer will stick to the rollers, and the more the resin accumulates on the rollers, the harder it becomes for the rollers to turn. Plus, once the resin dries, it's extremely tough and hard to clean! So only a conveyor belt dryer is suitable, a roller dryer can't be used.
