Product Description

The biomass veneer roller dryer has the biggest feature of lowest production cost in drying one cubic meter green veneer, namely USD 6-11/m³ including the cost of labor, fuel and electricity. The biomass burner works as the heat source whose function is like steam boiler or thermal oil boiler. But the biomass burner can burn waste wood, tree barks, waste veneer from veneer peeling machine or slicer directly to heat air and supplying to the dryer instead of indirect heating of water or oil. The temperature supplied from biomass burner to the veneer roller dryer is 140-180℃ which is adjustable according to the veneer thickness and moisture content. Typically the biomass veneer roller dryer is divided into feeding section, heating or drying section, cooling section and discharging section. 

Main Technical Specification

 Analysis and Comparison of Fuel Cost

In conclusion, the composite cost of drying one cbm veneer is $6 -$11 including the dried waste wood cost, labor cost and electricity cost which is the lowest production cost compared to the other type veneer dryers.

Advantages 

-- High Productivity, Energy Efficiency, Lowest Drying Cost and Perfect Drying Effect.

-- High temperature roller drum directly contact with wet veneer for heat transfer, and the heat efficiency is high, heat loss is reduced.

-- The veneer after drying has uniform MC, flat without split, buckle or end waviness, the surface is in good condition for gluing, and avoid collapse and honeycomb.

-- Automatic electric control system, frequency conversion, which can adjust the transmission speed and temperature automatically according to different veneer thickness and moisture content to achieve and ideal drying effect

-- Adopts step by step heat transfer, and different specifications for each section. The hot air in the heat exchanger can be uniformly emitted to the veneer.
