wood drying

Our drying chambers use the effect of dehumidification to dry the wood. We also offer wood sterilization to get rid of bugs and insects in the wood.

what is included

• Moisture content readings.
• Air dry wood.
• Wood drying chamber.
• Heat sterilization (optional).
• Properly spaced stacking.

Wood drying services

This is the first step in getting the wood to its optimum moisture content.

• The wood is stacked inside the chamber with appropriate spacers to minimize warping and cupping.
• We have a dehumidification drying chamber that uses a refrigeration system to remove moisture from the wood.
• Chamber drying can take anywhere from 2 - 7 days, depending on the thickness and moisture content of the wood.
• $1,500 – $4,500 /wood inch, depending on quantity and initial moisture content. Average is about $2,400/lumber inch, additional pickup and delivery charges may apply.

heat sterilization

Logs and wood in general, when left stacked for a long time, often attract bugs, insects and fungus.

• We use heat sterilization to remove unwanted elements and make the wood safe for use.
• $2,000/wood inch. additional charges apply for pickup and delivery

what to expect

• We use a moisture meter to monitor the moisture content of the wood throughout each stage of the process, managing the rate of drying until equilibrium moisture content is reached.
• Wood that has not been properly seasoned will warp, cup, warp, and crack over time. This can make surfaces uneven, bend frames, and cause permanent damage to the part, rendering it unusable.
• Our wood drying process begins with air drying because it dries the wood at a slower rate to minimize cupping and warping. Then the pieces are placed in the dehumidification oven to reach the final equilibrium moisture content (between 8% and 12%). Kiln drying can significantly shorten drying time and allows for faster turnaround time on projects.

Operating principle:

The TROCKNNER heat pump dryer uses the reverse Carnot principle to absorb heat from the air and transfer it to the room to increase the temperature of the drying room. The basic components of the heat pump dryer are: Compressor, heat exchangers, expansion device and other components that make up the refrigeration circuit. The compressor circulates the refrigerant in the system and enters the condenser and releases high temperature heat to heat the air in the drying chamber. At the same time, it cools down and turns into a liquid. After that, the liquid quickly absorbs heat, and then evaporates again to become a gas. At the same time, the temperature dropped from minus 20 °C to 30 °C. At this time, the air around the radiator will continuously transfer heat to the coolant. The refrigerant circulates continuously to transfer heat from the air to the drying chamber to increase the air temperature in the room.
