David Reznik conducts research on the physics of wave phenomena to reduce water and biological oxidation.

A chemical engineer with an advanced degree in food science and engineering, Reznik began his career in metal packaging and food processing in 1967, later forming his own R&D company in Israel before joining Tri Valley Growers. In 1982 he launched Tri-Valley’s Technical Research Center, which was spun off as Raztek Corp. five years later. Reznik serves as president and R&D director of the Sunnyvale, Calif.-based firm, which develops technology for food processing and can manufacturing. Electroheaters pass high-voltage electricity via graphite electrodes along the flow line of a fluid. Voltages of opposite polarity are applied to the first and second electrode assemblies to heat the product as it flows through the apparatus. The conduit is made of nonconducting, food grade materials.
