Self contained popcorn popper
An improved popcorn popper ( 10 ) has effluent filtration structure to treat the oil laden vapor and steam effluent from popping popcorn within the popper and with discharge of effluent having less than 5 milligrams of particulates per cubic meter of effluent discharged directly into the area in which the popper ( 10 ) is located. There is no need for external hoods or for external ducting of effluent to outside the area and facility in which the popcorn is popped. The filtering is carried out within the popper ( 10 ). A fire suppression system is provided to handle fires even within the kettle ( 14 ). Methods are disclosed.
1. A self-contained popcorn popper for use in an area, comprising:
a cabinet including a popcorn receiving chamber;
a popcorn popping kettle assembly including a kettle and a kettle top located within the popcorn receiving chamber;
a popped popcorn bin in the popcorn receiving chamber for receiving popped popcorn from the kettle;
a self-contained vapor and particulate filtering system integrated with the self-contained popcorn popper and being configured to remove oil and particulates from a vapor effluent issuing from the popping of popcorn in the kettle; and
a self-contained fire suppression system integrated with the self-contained popcorn popper and being configured to suppress a fire within the self-contained popcorn popper through emission of a fire suppression agent via the fire suppression system,
wherein the kettle top has at least one opening and baffle structure rigidly fixed in a stationary position relative to and supported by the kettle top beneath the at least one opening and the kettle top,
wherein the baffle structure is configured to define a tortuous path for egress of smoke and vapor from the kettle and to allow ingress of the fire suppression agent emitted by the fire suppression system into the kettle,
and further wherein the baffle structure and the at least one opening are movable relative to the kettle in response to at least a portion of the kettle top moving relative to the kettle, wherein the fire suppression system comprises a source of a fire suppression agent and a plurality of suppression agent delivery conduits terminating in a plurality of agent dispensing outlets located within the self-contained popcorn popper.
2. The popper as in claim 1 wherein the fire suppression system is further configured to suppress a fire within the kettle.
3. The Popper as in claim 1 wherein the plurality of agent dispensing outlets comprise a plurality of agent dispensing nozzles located within the self-contained popcorn popper.
4. The popper as in claim 3 wherein at least one of the plurality of agent dispensing nozzles is located within the vapor and particulate filtering system.
5. The popper as in claim 3 wherein at least one of the plurality of agent dispensing nozzles is located within the popcorn receiving chamber.
6. The popper as in claim 3 wherein at least one of the plurality of agent dispensing nozzles is directed at the kettle.
7. The popper as in claim 3 wherein the cabinet has two opposite sides which are each open for operator access therein.
