Abstract

Abstract A food preparation table in which perishable ingredients are maintained in a refrigerated state in a conveniently accessible location to a food preparer. The table includes means for providing the circulation of refrigerated air over the ingredients as well as in an adjacent refrigerator cabinet. Collecting trays adjacent the table surface are also refrigerated and preserve surplus ingredients which would otherwise be wasted in the food preparation process.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 267 words
A food preparation table including a means for maintaining foodstuffs in a continuous refrigerated state including: a work surface operatively disposed above a refrigerated area providing a work zone in which food ingredients are assembled; the food preparation table including a collection pan beneath the work surface, said work surface including a series of spaced openings of predetermined size thru which food pieces will pass to the collection pan and in which at least the bottom surface of the collection pan is refrigerated; said work surface being adjacent a refrigerated ingredient zone in which food ingredients are maintained in an accessible open relationshp with respect to the work surface; an enclosure for the refrigerated ingredient zone adjacent said work surface; said enclosure presenting an open front facing the work surface and having a fixed top surface extending above the food ingredients and including a means for providing a circulating flow of diffused refrigerated air flowing over the top surface of the food ingredients; said means including a cooperating diffuser plate and an air duct at separate locations adjacent the ingredient zone, whereby refrigerated air will flow between the plate and duct over the food ingredients; and a source of refrigeration for providing refrigeration adjacent the work surface and for providing the circulating flow of diffused refrigerated air over the top surface of the food ingredients in the refrigerated ingredient zone; said work surface being the upper surface of a lower cabinet on which lower cabinet the enclosure for the ingredient zone is mounted and in which cabinet the source of refrigeration is contained in a separate zone.
Claim 2
Dependent Claim 267 words
A food preparation table including a means for maintaining foodstuffs in a continuous refrigerated state including: a work surface operatively disposed above a refrigerated area providing a work zone in which food ingredients are assembled; the food preparation table including a collection pan beneath the work surface, said work surface including a series of spaced openings of predetermined size thru which food pieces will pass to the collection pan and in which at least the bottom surface of the collection pan is refrigerated; said work surface being adjacent a refrigerated ingredient zone in which food ingredients are maintained in an accessible open relationshp with respect to the work surface; an enclosure for the refrigerated ingredient zone adjacent said work surface; said enclosure presenting an open front facing the work surface and having a fixed top surface extending above the food ingredients and including a means for providing a circulating flow of diffused refrigerated air flowing over the top surface of the food ingredients; said means including a cooperating diffuser plate and an air duct at separate locations adjacent the ingredient zone, whereby refrigerated air will flow between the plate and duct over the food ingredients; and a source of refrigeration for providing refrigeration adjacent the work surface and for providing the circulating flow of diffused refrigerated air over the top surface of the food ingredients in the refrigerated ingredient zone; said work surface being the upper surface of a lower cabinet on which lower cabinet the enclosure for the ingredient zone is mounted and in which cabinet the source of refrigeration is contained in a separate zone.
Claim 3
Dependent Claim 26 words
The food preparation table of claim 1 in which the work surface comprises an arrangement of spaced extending rod elements in the form of a grill.
Claim 4
Dependent Claim 40 words
The food preparation table of claim 1 or claim 2 in which the same source of refrigeration provides refrigeration for the circulating flow of diffused refrigerated air flowing over the ingredient zone and for the refrigeration adjacent the work surface.
Claim 5
Dependent Claim 77 words
The food preparation table of claim 1 or claim 2 including a refrigerated cabinet beneath the work surface, which refrigerator cabinet includes a means therein to provide the circulation of refrigerated air between the duct and diffuser adjacent the ingredient zone and the cabinet, and in which the bottom surface of the collection pan is exposed to the refrigeration maintained in the refrigerated cabinet and operatively provides the refrigeration for the work surface disposed above said pan.
