Dx microwave wood kiln

Types of DX Microwave Wood Kilns

A device that uses radiation-emitting wave energy to remove moisture from wood is known as a microwave wood kiln. Many designs for microwave kilns have been proposed, all of which rely on a similar principle of drying wood through microwave energy. The DX microwave wood kiln has several models of varying sizes and capacities.

The microwave-modified MX-1 model has a chamber capacity of 1,000 board feet of lumber and a drying time of 1 to 2 weeks for thicknesses of up to 4 inches. It is built from a standard commercial microwave unit that is altered to dry wood instead of heating food. An industrial microwave with 200,000 watts of power forms the basis of the design for the DX-1 model. The entire unit can be moved with the aid of forklift slots. The drying time for wood with this model is 6 to 20 days depending on the thickness and species. A power source of 1000 watts per cubic foot of space for every load is needed.

An industrial microwave with 400,000 watts of power is the basis of the DX-2 model. Its chamber capacity is 2,000 board feet of lumber, and the wood dried with this model takes 6 to 20 days. More optional features are available with this model, such as a loading door on one or both sides, an end wall, a vent pipe assembly, an exhaust fan, and baghouse filters. An entire unit in this series is 32 feet long, 15 feet deep, and 15 feet tall. Some specific DX-2 models have a vent assembly with an exhaust fan that can be installed with reverse flow bag filters.

The DX-3 model has a chamber capacity of 3,000 board feet of lumber and is built to double-stack, triple-stack, or U-shaped configurations with stainless steel. The material for this model, galvanized steel, is 14-gauge. The wood dried with this model will have the same quality as lumber from a DX-2 kiln. The operating temperature of this model is up to 150 degrees F. Super-60 baghouse filters with 6,500 CFM are included in this model.

A moisture content as low as 15% is possible for the DX-4 model. The chamber capacity of this model is 4,500 board feet of lumber. Its capacity can range from 1,200 to 15,000 board feet of lumber. The age of the wood really matters when calculating the number of hours needed to dry it. When an industrial microwave with 600,000 watts of power is used to build the DX-5 model, the chamber capacity will be 6,000 board feet of lumber. It will have the same features and optional components as the DX-2 model described above. The operating temperature of this model is up to 180 degrees F.
