Title:
PRODUCE WASHING SYSTEM UTILIZING MULTIPLE ENERGY SOURCES
Document Type and Number:
WIPO Patent Application WO2001019539
Kind Code:
A3
Abstract:
A produce cleaning system (20) and process (10) that employs plural forms of energy in an ionic liquid-based washing system (22, 24, 26) is described. The washing system (22, 24, 26) includes employing solvents and solutes in the wash bath (24) which promote the conduction of electrical energy. The electrical energy can be applied to the produce in the wash bath (24) in various waveforms, such as a modulating wave superimposed on a carrier wave. Additionally, ultrasonic energy is employed to provide high-frequency mechanical pressure waves against the produce. The electrical energy and the mechanical energy combine to produce energy in the applicable resonant frequency range that acts to destroy or transform pathogens, dirt and synthetic molecules that may exist on the produce to either destroy them or render them harmless.
