Drying capacity had been a bottleneck in production at Koskisen’s sawmill for years, and the capacity of the old dryers was stretched to the limit prior to the investment.
“Now it appears that soon we will need to do something about our sawing capacity in order to fill up the dryers,” says Project Manager Osmo Oksanen with satisfaction.
The new progressive kiln is ideal for the efficient and high-quality drying of both heartwood and boards. In terms of average tree species and dimensions, the kiln produces 62,000 cubic metres of shipping-dry timber a year, and even considerably more with the right dimensions.
“The new kiln is superior in terms of drying technology properties. For example, the pressure frames in the ceiling press down on the stack during drying, which helps keep the boards straight and reduces the moisture-content spread,” explains Mikko Pitkänen, Valutec’s Country Manager for Finland.
