BG1933B Three-Deck Mesh-Roller Combined Veneer Dryer

Our product is a kind of straight-conveying transverse- circulating net-roller dryer, provided with both net and roller structures. net-roller veneer dryer has two kinds' layers of net and roller; it can be in process to dry for face plate and thick core plate at the same time. It has the advantages of less ground space and multi-use of one machine. Our product is a kind of straight-conveying transverse- circulating net-roller dryer, combining advantages of European dryers. It uses the side equipped centrifugal fans( air flow 62 thousands m3/h). New heat exchanger and rectangle variable cross-section spray boxes make the veneer surface uniformity for heating air. Heating sections fans of front and back areas are equipped by left and right, so they make the veneers the same final humidity after dried. In addition, for the damp climate condition, the dyer adds the cooling open sections length, it is advantages for veneers cooling that it avoids getting damp. The dryer's heating system use steam or oil boiler. When it uses the oil boiler, it needs to know the system safety, heating system tubes and heating exchangers should avoid carbon deposit and fire accident. Don't let water, acidity and low boiling point material into system.

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.

Routine Checks for Stable Veneer Drying

Operators should regularly inspect heat-supply pressure, condensate discharge, fan operation, exhaust-air settings, conveyor condition and heat-exchanger cleanliness. Recording inlet moisture, outlet moisture, line speed and drying temperature makes it easier to identify trends before they become production problems.

Five Factors That Affect Veneer Dryer Capacity

Dryer output is influenced by drying temperature, initial veneer moisture, wood density, veneer loading density and heat-exchanger cleanliness. Because these conditions vary between factories, published capacity figures should be treated as configuration references. A reliable selection should be based on the customer's actual material and production data.

How to Select a Veneer Dryer

Choosing a dryer starts with the veneer itself. Face veneer, core veneer and mixed production lines often require different conveying structures. Buyers should prepare veneer species, dimensions, thickness, initial and final moisture, daily output, heat source and available plant space. This information helps determine whether a mesh belt, roller or combined dryer is the right starting point.
