The company does engineering, sales and service of drying systems and was founded in 1982 as a Wisconsin Corporation by Wilfried P Duske.

Mr. Duske holds a M.S. in Engineering Mechanics from the University of Wisconsin-Milwaukee and is a registered Professional Engineer. He has worked in the dryer field since 1964 with the Heil Company where he was chief engineer until 1978 when he left. The Heil Company was a major builder of rotary dryers at the time and was the first company to introduce the triple pass rotary dryer.

During the twenty plus years of it’s existence Duske Engineering Company has established itself as a major supplier of rotary drying systems to the meat packing industry, drying by-products such as bone meal, blood meal, feather meal and sludge.

Many other products are dried in Duske dryers, such as fish meal, chicken manure, compost, alfalfa, egg shells, wood particles and many more.

More than 100 new dryers have been built and many dryers of other manufactures have been rebuilt and reconditioned to suit specific products. Duske dryers are in operation in North America, Samoa, New Zealand and Australia.

The line of dryers includes triple pass and single pass drums with capacities ranging from 1,000 lb/hr (455 kg/hr) to 25,000 lb/hr (11.5000 kg/hr) water evaporation. The smaller units up to 5,000 lb/hr (2,275 kg/hr) evaporation can be pre-assembled at the factory for legal size truck shipment and easy plant installation.

The company has been an innovator in the dryer design and holds several U.S. Patents related to the drying industry.

In support of the drying systems the company maintains a spare parts inventory and provides field service including start-up, training of customer personnel, and trouble shooting.
