BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention is directed to an apparatus and method for thawing a frozen commodity such as a food product.
2. Description of Background Art
A problem occurs in the food industry when it is desired to thaw a food product. For example, the food products may be positioned on a loading dock and subjected to ambient air to thaw the food products. Normally, a plurality of pallets of food products are arranged on the loading dock or in a warehouse and ambient air is blown or pushed towards the pallets. If the ambient air is at 72° Fahrenheit (22.22° Celsius), the first pallet of food products will thaw first and may reach a temperature above the mandated safety zone of 40° Fahrenheit (4.44° Celsius). The thawing of the food products on a loading docket or in a warehouse may lead to the growth of bacteria in the food products that may be transmitted to contaminate adjacent food products and other areas of the warehouse. In addition, the thawing of a food product in this manner may lead to the discoloration of the food product. Further, the food products will be thawed unevenly and thus lead to problems in determining which food products are properly thawed for delivery to a customer. Still further, the thawing of frozen food products in ambient air leads to the production of condensation within the boxes of the food products. This will produce a wet or soggy box with a wet food product that is not suitable for delivery to a customer.
Another way to thaw a food product is to position the food product in a cooler that is maintained at a temperature of approximately 37° Fahrenheit to 70° Fahrenheit (2.77° Celsius to 21.11° Celsius). Again the pallets of food products have air that is blown or pushed towards the pallets. The pushing of the air unto the pallets of food products will lead to the thawing of the food on the pallet that is located immediately adjacent to the air handler. Pallets of food products that are displaced away from the first pallet will be thawed at a different rate. It is difficult to determine when the various pallets of food products are properly thawed. Uneven thawing will lead to the need to use a longer time to thaw the food products. By using the conventional blowing or pushing of air method towards the food products, it takes approximately 7 to 10 days to thaw a frozen food product, such as ham or turkey, in a cooler.

However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
As illustrated in
A cover C is positioned to be placed on the space S to seal the two rows of pallets along the top space S. In addition, the cover C may be positioned on at least on a portion of the top surface 12 of the commodities for sealing the two rows of pallets along the top surface to form the plenum. In addition, the cover C may also extend along end surfaces 14, 16 for sealing the space S between the two rows of pallets to form the plenum. In another embodiment, the cover C may extend along at least a portion of the top surface 12 and the end surfaces 14, 16 to seal the space S and to form the plenum. The cover C may be a flexible tarp for positioning on the top surface of the commodities that is sucked up tight to make a seal as air is pulled through the space S formed between the pallets and through the ventilation holes H in the boxes stacked on the pallets. In another embodiment, the cover C may be a more rigid board material that is positioned on the space S or on at least a portion of the top surface of the commodities.
As stated above, it is to be understood that the two rows I and II of pallets 1A-5A, 1B-5B and 1C-5C, 1D-5D may be arranged in straight rows as illustrated in
A plenum P is formed between the two rows I and II of the pallets 1A-5A, 1B-5B and 1C-5C, 1D-5D with the plurality of pallets being spaced apart 11A-14A, 11B-14B, 11C-14C and 11D-14D from adjacent pallets to permit a flow of air therebetween. The boxes of commodities positioned on the pallets include a plurality of ventilation holes H for permitting air to be pulled through the boxes as the commodity is thawed.
The air handler 20 is positioned between the two rows I and II of pallets and is spaced along a length thereof. As illustrated in
As illustrated in
As illustrated in
By positioning the air handler 20 between the rows I and II of pallets, an even flow of air is achieved from between adjacent pallets 11A-14A, 11B-14B, 11C-14C and 11D-14D and along the two rows I and II of the pallets 1A-5A, 1B-5B, 1C-5C and 1D-5D and through the holes H in the boxes for evenly thawing a commodity positioned in the boxes on the pallets.
As illustrated in
In one embodiment of the present invention, the pallets are positioned in a cooler wherein the temperature of the cooler is maintained at approximately 37° Fahrenheit to 70° Fahrenheit (2.77° Celsius to 21.11° Celsius). The commodity may be raised to a temperature above the mandated safe zone of 40° Fahrenheit (4.44° Celsius) for no more than four (4) hours and thereafter should be lowered to be below the mandated safe zone of 40° Fahrenheit (4.44° Celsius). At least one air handler is provided for pulling air within a predetermined temperature range through the ventilation holes in the boxes and along a length of the space S formed between the two rows and discharging the air therefrom for thawing the commodity while not raising the temperature of the commodity above a mandated safe zone for longer than a predetermined time. To thaw a frozen food product it is necessary to remove the latent heat of the frozen product to be in a state where the frozen food product is thawed. Removing latent heat requires additional BTUs as compared to cooling a product from a warm temperature of 70° Fahrenheit to 85° Fahrenheit (21.11° Celsius to 29.44° Celsius) to a lower temperature of 60° Fahrenheit to 65° Fahrenheit (15.56° Celsius to 18.33° Celsius). According to the present invention, the thawing in a cooler occurs in approximately 24 to 36 hours. A substantial amount of energy can be conserved by using the cold air from the frozen product to maintain the temperature in the cooler at approximately 37° Fahrenheit to 70° Fahrenheit (2.77° Celsius to 21.11° Celsius). The cold, frozen product provides cooling for the cooler.
The present invention includes a method that may be used to thaw the commodity, such as a food product. The thawing of the commodity may be performed in a cooler that is maintained in a temperature range from 37 degrees F. to 70° Fahrenheit (2.77° Celsius to 21.11° Celsius) below the mandated safe zone of 40 degrees F. (4.44° Celsius) for thawing food products within the safe zone. At least one air handler is provided for pulling air within a predetermined temperature range through the ventilation holes H in the boxes and along a length of the space S formed between the two rows and discharging the air therefrom for thawing the commodity while not raising the temperature of the commodity above a mandated safe zone for longer than a predetermined time.
The present invention may be used with any number of pallets arranged in straight rows or in rows disposed at an angle relative to each other. The air handler 20 is portable for positioning the air handler 20 in a warehouse, a cooler, on a loading dock or in any environment for permitting the thawing of a commodity as the need arises. The present invention is not limited for use in a cooler. The present invention provides for tempered thawing for ensuring that a commodity is properly handled depending on the conditions required for the commodity.
The speed of thawing permits the present invention to process a commodity very quickly. For example, with regard to a food product, a code date is provided for the food product that starts to run as the food product is thawed. If the code date is 10 days, a conventional way of thawing the food product would take approximately 7 to 10 days. Thus, the code date has expired or almost expired by the time the food product is thawed. According to the present invention, the thawing occurs within 24 to 36 hours. Thus, a substantial time still remains with regard to the code date for permitting a customer to have sufficient time to use the food product in a restaurant or to sell the food product in a grocery store.
Pulling the air through the pallets makes it possible to form a plenum to block the air flow where needed by using a tarp that is sucked up tight to the space S to make a seal for forming a plenum or for the cover C to engage at least a portion of the top of the boxes to make a seal as compared to providing a rigid structure. By pulling the air through the pallets and through the ventilation holes H in the boxes stacked on the pallets the air flow seals the tarps to the space S or to the product without the need of using a rigid structure.
As illustrated in
A cover C is positioned to be placed on the space S to form a plenum or may be positioned on at least on a portion of the top surface 112 of the commodities for sealing the two rows of pallets along the top surface. In one embodiment, the cover C can also extend along end surfaces 114, 116 for sealing the space S between the two rows of pallets along the space S or the cover C may extend along both the top surface 112 and the end surfaces 114, 116. The cover C may be a flexible tarp for positioning on the space S or on the top surface of the commodities that is sucked up tight to make a seal as an air flow is pulled through the ventilation holes H. In another embodiment, the cover C may be a more rigid board material that is positioned on the space S or on the top surface of the commodities.
