Jackson has been involved in the drying of wood shavings since 1979. In that time, we have seen a number of different methods employed, with varying degrees of success. Our experience has shown that the most cost-effective and efficient method for drying wood shavings is the use of triple-pass drum dryers(click for Brochure), such as those pioneered in the 1920s by the Arnold Dryer Company of Milwaukee (later a division of the Heil Co.). New drum dryers are now built by Baker-Rullman Mfg. and others, and reconditioned used units are also a popular and economical option when available.

The Ideal Method

This simple, direct, and highly effective method of drying has been successfully applied in the dehydration of a wide range of materials; and has proved to be the ideal method for drying shavings. The drying drum features an expanding cross-sectional area and a compound showering flight pattern which guarantees maximum exposure of all particles to the drying medium. The velocity and temperature of the air stream are different in each of the three passes to suit the changing rates of evaporation as the moisture content of the shavings decreases.

How It Works

Choices and Costs of Fuels

Traditionally, these drum dryer systems have been fired with either fuel oil or natural gas burners; but the current equipment of choice is a biomass solid fuel Webb Burner™. These burners offer very significant advantages:


  1. They are substantially more economical to operate when fuel costs are taken into account. Fuel savings of 80% to 99.5% are not uncommon.

  2. They are very environmentally friendly; generating virtually no polluting emissions, and producing no net gain in the "greenhouse" gases associated with global warming.

  3. They help alleviate needless depletion of limited fossil fuel reserves and reduce dependence on foreign petroleum.

Our Expertise

Jackson has been a leader in the wood shaving industry for over 40 years. In that time, we have manufactured over 200 wood shaving mills, and have worked with many customers over the years to set up entire shaving plants. We bring this unparalleled depth of experience to every customer -- whether building one of our smallest shaving mills for a one-man owner/operator just getting started, or designing, installing, and starting up a complete plant layout "from scratch."

We can:

Afterward, we follow up to make sure everything is right, and provide on-going support for replacement parts and service work if necessary. We would be happy to discuss your project -- simply give us a call at (715) 926-3816, or see the "Contact Us" page.
