Method for providing ozone sanitation of fruits and vegetables

This invention describes a system for washing fruits and vegetables with ozonated water to kill germs. It uses an ozone generator to mix ozone gas into temperature-controlled water, creating a sanitizing solution. The process involves first washing the produce with warm ozonated water, followed by a chilled ozonated water wash to cool the items and help them retain moisture.

Why it matters: Filed before compact, energy-efficient ozone generators and precise digital temperature controls were widely available. These advancements now make integrating such a system more practical and cost-effective for point-of-sale applications.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateOzone generator, pumps, temperature controls, tanks.
