Abstract

A food preparation table includes a housing at least in part defining multiple food pan receiving locations and a cooling air flow path internal of the housing below the food pan receiving locations. A first food pan is positioned within a first one of the food pan receiving locations such that side walls and a bottom wall of the first food pan are within the cooling air flow path, a first one of the side walls of the first food pan includes a plurality of openings therein to permit some cooling air to enter the first food pan and flow in contact with food items therein.

First claim

What is claimed is:

1. A food preparation table, comprising:
a housing at least in part defining multiple food pan receiving locations, a refrigeration system within the housing and a cooling air flow path internal of the housing and leading from the refrigeration system to a region below the food pan receiving locations and back to the refrigeration system;
a first food pan positioned within a first one of the food pan receiving locations such that side walls and a bottom wall of the first food pan are within the cooling air flow path, a first one of the side walls of the first food pan includes a plurality of openings therein to permit cooling air to enter the first food pan and flow in contact with food items therein, and the bottom wall of the first food pan includes a plurality of openings therein to allow the passage of cooling air therethrough, wherein the plurality of openings in the first one of the side walls are distributed along a majority of a height of the first one of the side walls for effective distribution of cooling air through a depth of food items in the first food pan, such that cooling air delivered into the pans is recirculated back to the refrigeration system;
wherein the first one of the side walls is oriented parallel to a main flow direction of cooling air flowing past the first food pan along the cooling air flow path.

2. The food preparation table of claim 1 , wherein a second one of the side walls runs perpendicular to the main flow direction and has an external surface that faces against the main flow direction, wherein the second one of the side walls does not include any openings.

3. The food preparation table of claim 2 , wherein a third one of the side walls runs perpendicular to the main flow direction and has an external surface that faces toward the main flow direction, wherein the third one of the side walls does not include any openings.

4. The food preparation table of claim 3 , wherein a fourth one of the side walls is oriented parallel to the main flow direction, the fourth one of the side walls having a plurality of openings therein.

5. The food preparation table of claim 2 , wherein the first one of the side walls is longer than the second one of the side walls, such that a long direction of the first food pan is oriented parallel to the main flow direction.

6. The food preparation table of claim 1 , further comprising:
a second food pan within a second one of the food pan receiving locations such that side walls and a bottom wall of the second food pan are within the cooling air flow path, wherein the side walls and the bottom wall of the second food pan do not include any openings.

7. The food preparation table of claim 6 , wherein the first food pan holds solid food product, wherein the second food pan holds liquid food product.

8. The food preparation table of claim 7 , wherein the first food pan holds eggs in the shell, wherein the second food pan holds liquid eggs.

9. The food preparation table of claim 7 , further comprising:
a third food pan within a third one of the food pan receiving locations such that side walls and a bottom wall of the third food pan are within the cooling air flow path, wherein at least one of the side walls of the third food pan includes a plurality of openings.

10. The food preparation table of claim 9 , wherein the second food pan is located between the first food pan and the third food pan.
