August 15, 2006 - An industrial-scale system that utilizes PEF (pulsed electric field) technology, resulting in >5 log bacteria kill for food pasteurization and water purification applications, rather than harmful heat or chemicals, is being introduced by Diversified Technologies, Inc. of Bedford, Massachusetts.Diversified Technologies’ PEF System is a non-thermal, chemical-free, all solid-state system which passes liquefied food products or water through a chamber and subjects it to brief pulses of very high voltage.
Engineered and built to customer requirements with up to 10,000 LPH throughput, this industrial-scale sterilization system produces >5 log bacteria kill.Unlike heat processing in food applications, Diversified Technologies’ PEF System does not alter the flavor of foods or juices and requires much less energy to operate. In water purification applications, it eliminates the need for chlorine, ozonation, and other chemicals.
Power levels are offered from 25 kW to 750 kW, with full control over pulse and frequency.Diversified Technologies’ Industrial-Scale PEF Systems are priced from $250,000.00, depending upon configuration.
