Ozone rain pan
Embodiments of the present disclosure relate generally to systems and methods for combing ozone and water to deliver ozonated water in a rinse stream. The ozone rain pan finds particular use for rinsing food products traveling along a conveyor line with ozonated water.
1. A system for delivering ozonated water to an ozone treatment zone, the system comprising:
an ozone rain pan box defining a lower surface, side walls connected to the lower surface, and a lid configured to be positioned over the side walls to define a water containment portion within the ozone rain pan in use,
a plurality of openings spanning the lower surface, the plurality of opening sized and configured to allow water to flow therethrough via rainfall;
a baffle that defines a channel between the baffle and one of the side walls; and
at least one ozonated water inlet positioned to deliver ozonated water into the channel.
2. The system of claim 1 , wherein the side walls comprise two end side walls and two elongated side walls to define a rectangular ozone rain pan.
3. The system of claim 1 , wherein the side walls are between about 3 inches to about 8 inches high.
4. The system of claim 1 , wherein the plurality of openings range in size from about 0.02 inches to about 0.08 inches in diameter.
5. The system of claim 1 , wherein the plurality of openings are spaced from about 0.5 inches to about 1.5 inches between a center of one opening to a center of an adjacent opening and are arranged in a grid-like pattern.
6. The system of claim 1 , wherein the baffle is secured to the lower surface of the ozone rain pan and comprises baffle openings therethrough, wherein water collecting in the channel flows through the baffle openings or over the baffle or both, depending upon speed of water delivery.
7. The system of claim 6 , further comprising a second channel bounded by the baffle and a second baffle, wherein the second baffle is mounted between opposite side walls to form a flow channel under the second baffle.
8. The system of claim 7 , further comprising a third channel bounded between the second baffle and a third baffle secured to the lower surface of the ozone rain pan, wherein water from the flow channel flows over the third baffle.
9. The system of claim 1 , wherein the at least one ozonated water inlet comprises a first inlet positioned to deliver water to a channel located on one side of the water containment portion, and a second inlet positioned to deliver water to a second channel located on an opposite side of the water containment portion.
10. The system of claim 1 , further comprising a water overflow management system comprising an exit opening in one of the side walls that is bounded by an overflow wall.
11. The system of claim 1 , wherein the baffle comprises a baffle system positioned within the interior water containment portion, the baffle system comprising a plurality of baffles over and under which incoming ozonated water is caused to flow prior to entering a central water holding portion.
12. The system of claim 1 , wherein the baffle comprises a baffle system that comprises a series of three baffles, (a) a first baffle secured to the lower surface of the water containment portion and defining a first channel between a water containment portion sidewall and the first baffle, (b) a second baffle adjacent to the first baffle, the second baffle having a raised configuration such that water may pass through a flow channel defined thereunder, and (c) a third baffle adjacent to the second baffle, the third baffle secured to the lower surface of the water containment portion and having a height that is shorter than the first baffle.
13. The system of claim 12 , wherein incoming water collects in the first channel, flows over or through the first baffle, flows under the second baffle, and flows over the third baffle to enter a central holding portion of the water containment portion.
14. The system of claim 1 , further comprising an ozone destruct outlet fluidly cooperating with the ozone rain pan.
15. The system of claim 14 , wherein the ozone destruct outlet is positioned on the lid.
16. The system of claim 1 , further comprising an ozone destruct unit for treating removed off gassed air.
17. The system of claim 1 , further comprising one or more air openings in the side walls or lid for allowing fresh air to enter the interior water containment portion.
18. The system of claim 1 , further comprising adjustable legs or a shower head-like mount for mounting the ozone rain pan with respect to a conveyor.
19. A method for delivering a rain stream of ozonated water to an ozone treatment zone, comprising:
(a) mounting an ozone rain pan of claim 1 over the ozone treatment zone; and
(b) delivering ozonated water into the at least one inlet of the ozone rain pan.
20. The system of claim 1 , wherein the plurality of openings allow ozonated water to rain out from the ozone rain pan via gravity.
