Abstract
The invention relates to a condiment dispensing system for dispensing condiment and the like which includes a gas operated pump for moving condiments from a condiment source to a delivery nozzle through a pinch valve that operates to close and open the delivery flow path in response to and absence of gas pressure. A swipe valve to clean the delivery nozzle is also provided.
Claims8
A condiment dispensing system comprising a rack for holding a source of condiment having an outlet port;
- a pump having a condiment inlet and a condiment outlet;
- means for operating said pump;
- conduit means connecting the outlet port of the source of condiment with the condiment inlet of said pump;
- a delivery nozzle;
- delivery conduit means connecting said delivery nozzle with the condiment outlet of said pump;
- pinch valve means on said delivery conduit means between said condiment outlet and said delivery nozzle, said pinch valve means including a normally open central flow path for condiment flow;
- means for closing said flow path;
- and control means for activating said pump for dispensing condiment through said delivery nozzle, said control means including means to open said pinch valve and simultaneously start said pump to provide condiment delivery through said nozzle and means to stop said pump to close said pinch valve.

A condiment dispensing system comprising a rack for holding a source of condiment having an outlet port;
- a gas driven pump having a condiment inlet and a condiment outlet and a gas inlet for operating said pump;
- conduit means connecting the outlet port of the source of condiment with the condiment inlet of said pump;
- a source of gas under pressure;
- gas conduit means connecting said source of gas with the gas inlet of said pump;
- a delivery nozzle;
- delivery conduit means connecting said delivery nozzle with the condiment outlet of said pump;
- pinch valve means on said delivery conduit means between said condiment outlet and said delivery nozzle, said pinch valve including a normally open central flow path for condiment flow;
- means for closing said flow path in response to gas pressure;
- control conduit means connecting said source of gas with said pinch valve and operable to close said pinch valve when gas under pressure is flowed thereto and control means for activating said pump for dispensing condiment through said delivery nozzle, said control means including means for simultaneously operating said pump to dispense conduit through said delivery nozzle and means to close said pinch valve to stop condiment flow and to stop said pump.
