OTC continuous kiln

Valutec's OTC continuous kiln is based on a patented solution that minimizes the risk of checking for larger dimensions as well.

This kind of kiln is specially developed for producing boards and planks at an annual capacity of up to 100,000 m3 (43 mmbf) and a target moisture content down to around 12–18%.

OTC stands for Optimized Two-stage Continuous and the kiln has a climate development along the channel's lengthwise direction similar to a batch drying schedule. The combination of the continuous kiln's high capacity and the batch kiln's high quality provides a kiln that also manages rapid drying down to a low final moisture content. The kilns can advantageously be equipped with a heat recovery system.


The timber is dried as it is transported through the different climates in a drying channel with two separate zones. The timber is placed on trolleys and fed from a buffer track into the kiln's input end. A fully automatic feed system transports the timber through the kiln and on out at the output end. Axial fans in each zone blow circulation air via heat coils and through the timber. In the first zone, the air blows in the direction of the feed while in the second zone, it blows against the timber's feed direction.
