Thompson Dryers

Thompson Dryers

Since 1945 Thompson Dryers have been pioneering drying; patenting, perfecting and servicing dryer systems across many industries. Take a tour around one of our single-pass rotary drying systems. We believe equipment should work like it’s supposed to and you deserve the very best solution for your drying needs. Thompson Dryers is committed to bring products & services to the market that satisfy a need. If, in the early days, no one had needed a dryer that worked like it was supposed to, Thompson Dryers would not exist as we know it today, or at all. But Thompson Dryers looked at the needs of other dryer owners and operators, who were looking at the needs of their customers, and provided solutions accordingly. All the people we helped along the way were producing products that were in high demand. Today, the uses and capabilities of industrial dryers grow continually; they are increasingly essential to markets around the world.

Industries We Serve

Throughout the years Thompson has been involved with dozens of industries, hundreds of plants and numerous different products to dry.

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.
