BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention is directed to an apparatus for blast freezing a commodity such as a food product.
2. Description of Background Art
It is common in the food industry to use a blast freezer to freeze various food products. Normally, a blast freezer requires the use of an expensive specially designed tunnel in which food products are positioned on pallets within the tunnel. The tunnel is a freezer that is maintained at a temperature of approximately −40° Fahrenheit (−40° Celsius). Air is blown or pushed onto the food products disposed in the tunnel to freeze the food products. However, as the cold air is first blown or pushed towards the first pallet of food products to be frozen, the air is warmed by the temperature of the food products so that the second pallet in the row is exposed to a warmer air as compared to the first pallet of food products. This problem is exacerbated as air is blown or pushed towards the third pallet and thereafter the fourth pallet and subsequent pallets. Thus, the food products positioned on the last pallet will be frozen at a different time as compared to food products disposed directly adjacent to the air handler. After the food products are frozen, the food products are transferred to a freezer that is maintained at a temperature of approximately −20° Fahrenheit (−28.88° Celsius) or at a temperature of approximately −10° Fahrenheit (−23.33° Celsius).

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 or at least a portion of the top surface 12 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 14, 16 for sealing the space S between the two rows of pallets on the end surfaces 14, 16. The cover C may be a flexible tarp for positioning on the space S or on the top surface of at least a portion 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 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 a 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 to blast freeze the commodity.
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 treating a commodity positioned in the boxes on the pallets.
As illustrated in
The apparatus 10 of the present invention may be used as a blast freezer for freezing the commodity, such as a food product. By placing the pallets of food products in a normal freezer at a temperature in a range of approximately 8 degrees F. to −20° Fahrenheit (−13.33 degrees C. to −28.88° Celsius) and using an air handler 20 an even flow of air is achieved from between adjacent pallets 11A-14A, 11B-14B, 11C-14C and 11D-14D and through the ventilation holes in the boxes stacked on the pallets and along the two rows I and II of the pallets 1A-5A, 1B-5B, 1C-5C and 1D-5D for evenly blast freezing a commodity positioned in the boxes on the pallets. Thereafter the products may be positioned into a freezer that is maintained at approximately −10° Fahrenheit (−23.33° Celsius).
A substantial savings in energy is achieved by using the present invention to blast freeze a product. The expensive, specially designed tunnel that is maintained at a low temperature of approximately −40° Fahrenheit (−40° Celsius) is no longer needed.
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 freezer, or in any environment for permitting the treating of a commodity as the need arises. The present invention is not limited for use in a freezer. The present invention provides for blast freezing for ensuring that a commodity is properly handled depending on the conditions required for the commodity.
The speed of blast freezing permits the present invention to process a commodity very quickly.
The blast freezing of a food product according to the present invention occurs within 36 hours at a temperature of approximately −8° Fahrenheit (−22.22° Celsius). This is to be compared to a conventional tunnel that is used to blast freeze a food product in 72 hours at a temperature of approximately −40° Fahrenheit (−40° Celsius). Again, a substantial saving occurs by reducing the time and the energy needed for blast freezing the food product. Thus, a better turn over occurs to permit additional food products to be blast frozen by using the present invention.
Pulling the air through the pallets makes it possible to form a plenum to block the air flow where needed by using a cover C or tarp that is sucked up tight to make a seal with the space S as compared to providing a rigid structure. By pulling the air through the pallets and through the ventilation holes in the boxes stacked on the pallets the air flow seals the tarps to space S. In another embodiment, the cover C or tarp may be positioned on a portion of the top surface of the boxes wherein the seal with the space S is foamed without the need of using a rigid structure.
As illustrated in
A cover C is positioned to be placed on the top of the space S and may be positioned on at least a portion of the top surface 112 of the commodities for sealing the two rows of pallets along the top surface.
