Abstract

Apparatus for melting and heating shortening includes a housing having a top, a bottom and sidewalls; a heating grid mounted in the housing and spaced above the bottom thereof for melting shortening and allowing melted shortening to pass therethrough toward the bottom of the housing. A door is mounted to the housing for introducing a block of shortening onto the heating grid. A bottom heater is mounted adjacent the housing bottom for maintaining the melted shortening at a desired temperature. A control circuit maintains control of the operation of both the heating grid and the bottom heater in a predetermined fashion for initially melting a block of shortening introduced onto the heating grid while substantially preventing smoking of the same, and for maintaining melted shortening at the desired temperature.
