Description
- The present application claims priority to Provisional Application 62/625,343, filed Feb. 2, 2018, and the disclosure of the parent application is incorporated in entirety at least by reference.
- The instant invention is in the field of apparatus useful for defrosting frozen food items and pertains more particularly to a portable apparatus for re-circulating water over a frozen food item.
- Freezing food is a widespread practice for preserving food, and frozen food items have to be defrosted to be used. Common industry practice for defrosting frozen items include refrigerating at 40 degrees F. or running cold tap water over the frozen item. Both these methods have particular problems. When defrosting items in a refrigerator space that can be allocated for other storage is used. Defrosting food in a refrigerator is also time consuming. It can take up to several days to fully defrost frozen meat.
- The practice of running cold tap water over frozen items to thaw is faster than the refrigeration practice but is also subject to specific problems. To safely defrost an item a continuous flow of cold tap water is necessary at or below seventy degrees Fahrenheit to avoid bacterial growth. Defrosting food in this manner is highly inefficient because copious amounts of water are wasted. On average, for every minute that a sink faucet is fully on 2 or more gallons of water may be used. To defrost one pound of meat using the running water method generally takes around one hour. So a great deal of water may be wasted in defrosting one pound of meat.
- A culinary kitchen that defrosts with tap water typically uses approximately 17,700 gallons of water a month for defrosting. To comply with food and health regulations the water must be constantly moving and cannot be stagnant. The water also must be maintained at or below 70 F. as mentioned above.

The defrosting apparatus is placed on the bottom surface of the container with the opening fully beneath an upper surface of the water, and the pump is operated to re-circulate water from the container through the conduits to the downspout, and water from the downspout is directed over a frozen item to be defrosted.
- In one embodiment of the system the horizontally-oriented conduit is a telescoping assembly. In one embodiment the frozen item to be defrosted is placed on the bottom surface of the container away from the foundation unit of the defrosting apparatus, and the vertical and horizontal conduits are adjusted to place the downspout over the frozen item to be defrosted.
