Patent ID: 7237600

Claim:
A support surface for transferring heat between a source and food articles placed adjacent to said support surface, said support comprising: a) a plurality of longitudinally extending heat transfer support elements arranged substantially in parallel to form a substantially flat surface, each of said support elements having at least one longitudinal passageway therethrough extending from a first end to a second end thereof for transporting a heat transfer fluid, b) a first and second header for interconnecting the first end and second ends respectively, of said support elements in a fluid relationship, c) first and second end tube nipples for interconnecting said first and second header and said first and second ends of said support elements respectively in a fluid relationship, and d) a plurality of longitudinally extending flow control tubes of reduced diameter, operatively positioned by positioning means, in selective passageways of said support elements forming a reduced fluid passageway between said flow control tubes and said support elements that balances the fluid flow between said support elements and reduces the amount of heat transfer fluid therein.
