box 99 this allows a conventional food waste disposer to be easily connected to the food preparation sink system it also facilitates the control of the electronic control module 94 relative to activation of the food waste disposer 90 when desired the electronic control module 94 may include various settings to control the water flow into the sink 10 and operation of the food waste disposer 90 for example the electronic control module 94 may receive a signal from the switch 93 to initiate water flow into the sink 10 and then start the food waste disposer 90 after a delay of a set period of time following the water flow this allows the water to enter the sink 10 and flow down to the sump 43 before the food waste disposer 90 is started the water flow and the food waste disposer 90 may instead be started simultaneously in addition the electronic control module 94 may be set to turn the food waste disposer 90 off after a period of time of operation also the electronic control module 94 may be configured to sense operation of the food waste disposer 90 to determine when the disposal 90 is finished disposing of the waste this may be accomplished by sensing output voltage to the food waste disposer 90 e g sensing the rpms of the food waste disposer 90 or by sensing the turbidity of the water exiting the sink 10 or by other sensing means in some embodiments the food preparation sink may have only one nozzle the pressure of the water from the single nozzle may be spread across the entire bottom wall 21 instead a single nozzle may be mounted to oscillate and vary the water flow path along the bottom wall 12 however by using the.
