ABSTRACT:
An improved system, which conserves both energy and water, is provided for disposing of waste materials in environments such as restaurants and institutional food serving facilities. A commercial type food disposer unit having an electric motor for powering a mechanism for grinding or comminuting waste food materials and requiring running water for lubrication, flushing and/or cooling purposes is provided with an electric control circuit for automatically operating the motor and water supply valves associated with the unit in manner assuring both more efficient operation of the unit and minimum usage of electrical power and water. The control circuit of the system employs a plurality of interdependently actuated timer switches, at least certain of which preferably have adjustable length operating periods, in conjunction with various interrelated control relays for iteratively cycling the unit in an improved fashion, not only as to optimizing operation during individual cycles, but also as to iterated usage over a long or continuing period during which the motor is reversed with each successive cycle. When supplied with sources of electrical power and water, the system may be started or reset by simple actuation of a manual start switch, and will then function automatically until stopped by simple actuation of a manual stop switch. Since the disposer unit is operated only intermittently, wear and tear thereon, as well as electrical energy and water, are conserved by the improved system.
