Strands for OSB

Once called wafer boards, everyone has heard of the OSB boards used in construction and packaging; long, thin flakes (strands) from debarked logs are layered and then pressed into large boards.

The wood-based panel industry‘s modern, highly-efficient presses require a source material which exhibits a permanent uniform degree of moisture. 

This is where Siempelkamp Energy & Drying Solutions comes in:

Our single-pass drum dryers, which are heated with flue gas, ensure that both thick and thin strands always have the proper moisture content. Our energy and drying systems allow for the precise pre-treatment and drying of the wood material; this ensures that the OSB boards are always of the same high-quality. The entire process is precisely modulated and monitored. 
The flue gas required for heating the dryer is generated either in the grate firing system or in special combustion chambers with multifuel burners. Manufacturing wastes, e.g. bark, screening and waste material from board production, are used as fuel. Under certain conditions primary fuels such as oil or natural gas can also be utilised.

Efficient and reliable drying process

At large factories an energy system must often provide for two or more heat consumers acting partially independently from one another. Our sophisticated control concept for energy systems helps to provide a constant supply of heat to all consumers.
Our single-pass drum dryers make a significant difference to the quality of the finished OSB boards. With an efficient and reliable drying process, they allow for optimal, smooth production processes in the wood industry. And all of this globally.
