Glycol pan chiller systems
View Patent ↗A glycol pan chiller comprises a cooling area 110 cooled by glycol contained within a glycol void area 130, the void area defined within an inner liner 160. Under normal conditions, the glycol will remain stationary within the inner liner and will be chilled by a refrigerant line 140 contained within the glycol void area. For optional cooling, a separate glycol tank 230, stored away from the inner liner, is cooled by the refrigerant system, upon the cooling area 110 reaching a predetermined temperature, cooled glycol is circulated within the glycol void area.
1. A food cooling system, the system comprising:
a) an inner liner, the inner liner comprising an outer wall connected to an inner wall, the inner wall and outer wall defining a glycol void area, and an inside area of the inner wall defining a cooling area;
b) a refrigerant flow line disposed within the glycol void area;
c) glycol disposed within the glycol void area, the glycol in contact with the refrigerant flow line;
d) the refrigerant flow line containing circulating refrigerant, the refrigerant cooled by use a compressor, condenser and evaporation coil;
e) the glycol within the glycol void area cooled by contact with the refrigerant flow line;
f) the glycol disposed within the glycol void area having a pipe line to a glycol tank, the glycol tank comprising glycol and a second freon flow line, the second refrigerant flow line in direct contact with the glycol within the glycol tank cooling the glycol within the glycol tank; and
g) a thermostat and control valve measuring the temperature within the cooling area, and connected to a glycol pump, the thermostat and control valve activating the glycol pump upon the cooling area exceeding a predetermined temperature.
2. The system of claim 1 further comprising a removable layer of insulation in contact with the outer wall of the inner liner.
3. The system of claim 1 further comprising a plurality of food pans disposed within the cooling area and a lid attached with a hinge to a preparation table assembly, the lid, in a closed position preventing cooled air from reaching the food pans.
4. The system of claim 3 further comprising a tray shelf attached to the preparation table assembly, and the tray shelf attached to a raised chamber, the raised chamber containing the inner liner and glycol void area, the raised chamber further containing a plurality of support bars.
5. The system of claim 4 wherein the preparation table assembly further comprising a lower interior compartment defined by a door, a floor, a back wall and a ceiling, the back wall attached to the evaporation coil.
6. A method of cooling food, the method comprising:
a) using an inner liner, the inner liner comprising an outer wall connected to an inner wall, the inner wall and outer wall defining a glycol void area, and an inside area of the internal wall defining a cooling area;
b) using a refrigerant flow line disposed within the glycol void area;
c) using glycol disposed within the glycol void area, the glycol in contact with the refrigerant flow line;
d) using the refrigerant flow line containing circulating refrigerant, the refrigerant cooled by use a compressor, condenser and evaporation coil;
e) using the glycol within the glycol void area cooled by contact with the refrigerant flow line;
f) using the glycol disposed within the glycol void area having a pipe line to a glycol tank, the glycol tank comprising glycol and a second refrigerant flow line, the second refrigerant flow line in direct contact with the glycol within the glycol tank cooling the glycol within the glycol tank; and
g) using a thermostat and control valve measuring the temperature within the cooling area, and connected to a glycol pump, the thermostat and control valve activating the glycol pump upon the cooling area exceeding a predetermined temperature.
7. The method of claim 6 further using a removable layer of insulation in contact with the outer wall of the inner liner.
8. The method of claim 7 further using a plurality of food pans disposed within the cooling area and a lid attached with a hinge to a preparation table assembly, the lid, in a closed position preventing cooled air from reaching the food pans.
9. The method of claim 8 further using a tray shelf attached to the preparation table assembly, and the tray shelf attached to a raised chamber, the raised chamber containing the inner liner and glycol void area, the raised chamber further containing a plurality of support bars.
10. The method of claim 9 using the preparation table assembly further comprising a lower interior compartment defined by a door, a floor, a back wall and a ceiling, the back wall attached to the evaporation coil.
