We want to raise the bar for the standards
our customers expect when purchasing
industrial equipment and services.

Since 1945 Thompson Dryers has been pioneering drying: patenting, perfecting, and servicing dryers across many industries.  We build and service single-pass rotary dryer systems designed for your specific product and capacity needs.

Industries We Serve

Once the sugars and starches have been removed from the corn to make ethanol, the mash left over is wetcake, or WDGS – wet distillers grains and solubles.  It is quite nutritious for livestock since it has a relatively high protein content.  However, the shelf-life is very short if left in its wet state.  Thompson Dryers are used to process wet cake and syrup into distillers dried grains and solubles (DDGS) which can be stored longer and shipped further for use as a livestock feed product.

Biomass is the new buzzword on the street, well at least the energy production street. Biomass is a renewable energy source that can be grown in a sustainable way.  With world energy summits ending in promises to reduce and cap carbon emissions, the demand for renewables is rising.  Solar, wind, geothermal, etc. all have their place in the new energy economy, but the only way to replace a significant portion of energy generated by coal and other fossil fuels is through sustainable biomass.  Drying biomass saves on shipping costs and improves combustion characteristics.

Thompson dryers have many uses in the Forestry industry. In the building materials sector, our dryers help to create stronger, more consistent OSB, particle and waferboard products. In the pulp and paper sector, our dryers are used to create more efficient fuels out of sludge, hog fuel and forest residual products. Likewise, our dryers are used in conjunction with sawmills and other forest processing plants to use wood waste as a fuel or pelletized for consumer and industrial use.

As biomass is increasingly shipped worldwide, countries have become concerned about the possibility of cross contamination of insects and diseases. Thompson’s phytosanitary system design has been reviewed by the USDA and determined to meet the requirements of the European Union.

With higher demand for biomass, there is also an increasing concern for long term storage and fuel stability. Most biomass can be torrefied, which will transform the fuel into a hydrophobic substance that will not decompose readily. Torrefied material can also be added directly to coal-fired power plants, as it has very strong coal-like characteristics, without many of the complications that non-torrefied biomass exhibit. Thompson, through its alliance with Konza Renewable Fuels, is able to offer torrefaction systems that can process 50,000-tonnes/yr or 100,000-tonnes/yr.
