Distribution/retention plate for minimizing off-gassing
First Claim
1. An apparatus for promoting the efficient use of gas dissolved in a liquid by limiting the amount of off-gassing from the liquid, the apparatus comprising:
- a treatment chamber;
a liquid reservoir;
a distribution/retention plate separating the treatment chamber from the liquid reservoir; and
a pressure relief device to increase pressure in the liquid reservoir relative to the pressure in the treatment chamber and limit off-gassing from liquid in the liquid reservoir,wherein the apparatus is utilized in a dishwashing system and the distribution/retention plate comprises at least one downward flow passage to promote the flow of liquid from the treatment chamber to the liquid reservoir.

Abstract
An apparatus for promoting the efficient use of gases dissolved in a liquid by limiting the amount of off-gassing or evaporation from the liquid. The apparatus is a distribution/retention plate, may be utilized in a portable food washing system. The food washing system is a portable unit having a treatment chamber with an access door for the placement of food products on a loading plate. A food product is placed in the chamber and sprayed with ozonated water containing diffuse concentrations of ozone which reacts with and destroys organic contaminants on the food product. The distribution/retention plate is located at the bottom of the treatment chamber, and divides the treatment chamber from a reservoir and controls the rate of ozone off-gassing from the reservoir, thereby increasing ozone concentration in the water in the reservoir. In an alternative embodiment, the distribution/retention plate is utilized in an automatic dishwashing system.
