CONTACT HEAT TRANSFER COEFFICIENT DURING DOUBLE-SIDED COOKING OF HAMBURGER PATTIES

Contact heat transfer coeficient values during double-sided contact cooking of hamburgerpatties were calculated from grill plate temperatures, patty surface temperatures, and heat flux values. The patties were cooked for 130 s using different top and bottom grill plate temperatures (1 77C, I91 C, or 204C) and gap thicknesses between plates (10.0 mm, 10.5 mm, or 11.0 mm). Heat transfer coeficient values obtained were in the range of 250 to 650 W/m2C, depending on the cooking conditions. After reaching a maximum value, the coeflcient decreased and reached an asymptotic value at the end of the cooking cycle. The maximum heat transfer coeficient values depended on top or bottom grill plates and gap thicknesses between plates. Average heat transfer coencient values during 80 to 130 s of cooking depended on top or bottom grill plates and set grill temperatures.
