ABSTRACT:
An electrical control system for regulating the humidity of an enclosed atmosphere in a dough proof box or the like, comprising a cast metal steamer tray, incorporating an electrical heating element operable to heat the tray between selected upper and lower temperature limits determined by a thermostat responsive to temperatures of the tray casting. A time controlled valve supplies water to the tray for selected time intervals when the thermostat senses the tray's upper temperature. A humidistat controls operation of the thermostat. As a result, the steamer tray is heated between high and low limits and supplied with measured amounts of water to effect rapid generation of limited quantities of steam to satisfy the humidity levels demanded by the humidistat.
