Abstract
Abstract An apparatus is provided for heating a continuing series of articles, such as canned or bottled potable goods, to substantially room temperature in order to prevent condensation from forming on the containers. The apparatus comprises an elongated housing having an interior housing chamber and open on each longitudinal end. An endless conveyor transports the articles from one open end of the housing and to the other end of the housing along a substantially horizontal plane. An elongated trough is disposed under the conveyor and is partially filled with heating water so that the articles are partially submerged in the water as they are transported through the housing. A recirculation system is also provided for continuously reheating the heating water.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
159 words
Apparatus for heating a series of articles comprising: a housing having an interior housing chamber; an elongated reservoir formed in the bottom of the housing; means for transporting a continuing series of the articles substantially horizontally through said housing chamber from an inlet end of said housing and to an outlet end of said housing, said transporting means comprising a belt upon which said articles are supported, an elongated U-shaped trough having a base and a side portion extending upwardly from each side of the base, said trough base being positioned underneath and immediately adjacent said belt so that said trough side portions extend above the upper surface of the belt and wherein the ends of the trough are spaced inwardly from the inlet and outlet ends of the transporting means and positioned above said reservoir, and means for supplying a heated liquid to said trough in an amount sufficient to maintain a predetermined fluid level in the trough.
Claim 2
Dependent Claim
