It is responsible for unscheduled downtimes due to quality issues. The mitigation of segregation is a primary objective when handling mixtures and blends. Page 6 Shaft Seal Upgrade Reduces Cost, Product Loss A leaking mixer seal that requires replacement every six months is costly. These costs include lost product, extensive maintenance, increased downtime, and safety hazards. Page 40 Aeromechanical Conveyors for Brewery and Distillery Applications Breweries and distilleries face a common set of conveying challenges: Transporting the dry grain ingredients used as production inputs to the mixing vessel or mash tun. Page 44 Macrowave Bulk Pasteurization Systems Radio Frequency Co.'s new Macrowave pasteurization systems are ideal for batch or conveyorized applications for bagged or bulk product. In a Macrowave heating system, an RF generator creates an alternating electric field between two electrodes. The material to be treated is conveyed through an electrode array where this alternating energy causes polar molecules in the material to continuously reorient themselves to face opposite poles, much like the way bar magnets behave in an alternating magnetic field. The friction resulting from molecular movement causes the material to heat both rapidly and uniformly throughout its entire mass. Radio Frequency Company, Inc., Millis, MA 508-376-9555 www.radiofrequency.com Drum Screen System The Screenmaster RT features an internally fed, rotating drum screen, providing fine screening for a variety of applications, including wastewater treatment, pulp and paper processing, and manufacturing operations. The RT has a simple and reliable design. It employs a cylindrical screen constructed with perforated metal, wedge wire, or filter cloth, along with a weir system. In operation, the material is fed into the unit's inlet and is distributed along the internal screen surfaces. As the drum rotates, the weir moves the solids along the screen length. Solids are conveyed to the unit's discharge and liquids are drained via the unit's outlet port.
