Dupps Co. has completed construction of its Quad-Pass rotary drum dryer pilot plant for application trials.

Dupps Co., Germantown, Ohio, has completed construction of its Quad-Pass rotary drum dryer pilot plant for application trials. Prospective customers can use the pilot plant to judge drying effectiveness on nearly any raw material as well as calculate operational costs and measure end-product quality. The pilot facility is designed to provide an accurate model of a permanent QuadPass system¿s performance.

The pilot plant is a duplicate of the company¿s typical QuadPass system in every detail except size. The plant¿s dryer is rated at about 600 lb/hr of moisture evaporation, which is smaller than a normal installation. To complete the system, the dryer is coupled to a material-loading conveyor, propane or bio-mass heating system, drive train and centrifugal cyclone extractor. Raw material shipped to Dupps for testing is dried in the same way as a larger commercial system, providing the customer with verification of improvements in product quality and a complete, objective projection of return on investment. In addition, current Quad-Pass operators may test new, untried raw materials at the pilot plant before making any modifications to their installed dryer.

Although it is currently set up at Dupps¿ Germantown headquarters, the pilot plant can be shipped to and installed at the customer¿s location. This will allow customers to perform trials on biodegradable raw materials that are not suitable for shipping or to test under the same operating conditions as an anticipated permanent system.
