Wood Toasting/Drying

CFW Projects supplies wood seasoning and toasting solutions. We offer various solutions for different ambient conditions and customer requirements, for producers of any scale.

Our wood drying solutions have included:

  • Refrigeration-type heat pump dehumidifiers
  • Electrical heat and vent drying
  • Steam heat and vent drying
  • Hot water heating
  • Hybrid systems consisting of a combination of various components above to optimize and improve flexibility
  • Tunnel drying arrangements
  • Batch room drying systems
  • Containerized drying systems
  • Rental drying solutions
  • Wood toasting for oak barrel aging of wine

With the wide range of options we are able to offer cost effective solutions for drying. We also offer advice on improving existing drying systems together with upgrading / repairs and changing to new energy sources.

Besides the wood drying systems we have supplied in South Africa, we have also exported drying equipment and systems to Botswana, Mozambique, Zimbabwe and Malawi.

CFW also manufactures reversible flow fans used in wood drying kilns.

About Timber Seasoning

Timber seasoning is used to adjust the moisture content of wood so that it will be as nearly as possible in equilibrium with its surroundings. Wood naturally loses or gains moisture to adjust to its environment, but uneven and rapid change can result in various defects. The ideal final moisture content depends on the type of wood and its uses.

Controlled wood drying to moisture levels of below 30% helps to strengthen it and protect it from fungi, insects and other causes of decay. Dryer wood insulates more effectively and is more amenable to further processing with protective treatments, paints and fixing tools. The fact that it is lighter also reduces transport and handling difficulties and costs.

Sawed lumber is dried in kilns. The main drying challenges for wood processing operations are drying defects and high energy costs. The stresses that occur during drying can warp, check or otherwise damage the wood. Poorly controlled drying can also cause case hardening. The energy consumption of wood kilns is a result of heating and fan use, with kiln residency times that can be fairly long, particularly in unfavourable ambient conditions. Heating costs can be particularly high given the fact that hot, humid air may simply be exhausted from the kiln, wasting heat energy.

Various types of kiln are in use. Kilns that use heat generation to remove moisture are perhaps the most common, but dehumidifier kilns are also in use. Larger drying kilns typically use bi-directional fans to minimise the risk of uneven drying. By changing the direction of the airflow, the problems associated with higher evaporation rates near the inlet compared to the outlet are reduced.
