Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 279 words
Apparatus for smoking a quantity of comestible products comprising: conveyor means for moving a stream of said products along a predetermined path of travel; a first operating station positioned along said path for loading a supply of said product onto said conveyor means to form said product stream; a second operating station positioned downstream from said first station along said path for removing said products from said conveyor means; a smoking chamber positioned along said path intermediate said first and second stations arranged to receive said conveyor means and temporarily enclose a portion of said product stream; means to direct a supply of liquid smoke into said chamber; means to nebulize said liquid smoke to form a cloud of liquid smoke within said chamber in the path of said product stream, with the major portion of said cloud being formed from droplets of a size less than about 150 microns; means to circulate said cloud to bring said nebulized smoke into substantially uniform contact with the exposed surfaces of said product within said chamber; means to create a pressure differential between the interior of said smoking chamber and the surrounding atmosphere to prevent escape of any substantial portion of nebulized liquid smoke cloud from said chamber into the adjacent atmosphere; means to flush accumulated liquid smoke condensate from said chamber and said conveyor means; means to control the speed of travel of said conveyor means; and means to regulate the density of said smoke cloud within said housing; whereby a smokey flavor is rapidly imparted to said products by exposure of said product stream to said cloud of liquid smoke of a selected density for a selected time interval.
Claim 2
Dependent Claim 279 words
Apparatus for smoking a quantity of comestible products comprising: conveyor means for moving a stream of said products along a predetermined path of travel; a first operating station positioned along said path for loading a supply of said product onto said conveyor means to form said product stream; a second operating station positioned downstream from said first station along said path for removing said products from said conveyor means; a smoking chamber positioned along said path intermediate said first and second stations arranged to receive said conveyor means and temporarily enclose a portion of said product stream; means to direct a supply of liquid smoke into said chamber; means to nebulize said liquid smoke to form a cloud of liquid smoke within said chamber in the path of said product stream, with the major portion of said cloud being formed from droplets of a size less than about 150 microns; means to circulate said cloud to bring said nebulized smoke into substantially uniform contact with the exposed surfaces of said product within said chamber; means to create a pressure differential between the interior of said smoking chamber and the surrounding atmosphere to prevent escape of any substantial portion of nebulized liquid smoke cloud from said chamber into the adjacent atmosphere; means to flush accumulated liquid smoke condensate from said chamber and said conveyor means; means to control the speed of travel of said conveyor means; and means to regulate the density of said smoke cloud within said housing; whereby a smokey flavor is rapidly imparted to said products by exposure of said product stream to said cloud of liquid smoke of a selected density for a selected time interval.
Claim 3
Dependent Claim 185 words
Apparatus for smoking a quantity of comestible products comprising: means for moving a stream of said products along a predetermined path of travel; enclosure means defining a smoking chamber along said path arranged to temporarily receive a portion of said product stream; means to direct a supply of liquid smoke into said chamber; means to create a moving cloud of nebulized liquid smoke within said chamber in the path of said product stream; means to control the speed of movement on said product stream along said path to thereby control the residence time of said products in said smoking chamber; exhaust means operative to create a pressure within said enclosure means lower than the pressure of the surrounding atmosphere so that the resulting negative pressure differential thereby seals said liquid smoke cloud within said enclosure; and means to remove liquid smoke condensate from said chamber and said means for moving said product stream; whereby a smokey flavor is rapidly imparted to said products by exposure of said product stream to said cloud of nebulized liquid smoke of a selected density for a selected time interval.
Claim 4
Dependent Claim 185 words
Apparatus for smoking a quantity of comestible products comprising: means for moving a stream of said products along a predetermined path of travel; enclosure means defining a smoking chamber along said path arranged to temporarily receive a portion of said product stream; means to direct a supply of liquid smoke into said chamber; means to create a moving cloud of nebulized liquid smoke within said chamber in the path of said product stream; means to control the speed of movement on said product stream along said path to thereby control the residence time of said products in said smoking chamber; exhaust means operative to create a pressure within said enclosure means lower than the pressure of the surrounding atmosphere so that the resulting negative pressure differential thereby seals said liquid smoke cloud within said enclosure; and means to remove liquid smoke condensate from said chamber and said means for moving said product stream; whereby a smokey flavor is rapidly imparted to said products by exposure of said product stream to said cloud of nebulized liquid smoke of a selected density for a selected time interval.
Claim 5
Dependent Claim 236 words
Apparatus for smoking a quantity of comestible products comprising: means for moving a stream of said products along a predetermined path of travel; enclosure means defining a smoking chamber along said path arranged to temporarily receive a portion of said product stream; means to direct a supply of liquid smoke into said chamber; means to create a moving cloud of nebulized liquid smoke within said chamber in the path of said product stream; means to control the speed of movement on said product stream along said path to thereby control the residence time of said products in said smoking chamber; inlet and outlet ports included in said enclosure for said product stream; exhaust means operative to create a negative pressure Within said enclosure lower than the pressure of the surrounding atmosphere to thereby create a negative differential pressure substantially sealing said liquid smoke cloud within said enclosure, said exhaust means including means adjacent said ports to withdraw a substantial portion of the air induced into said enclosure through said ports by said negative pressure differential, to reduce the loss of nebulized liquid smoke from said housing; and means to remove liquid smoke condensate from said chamber and said means for moving said product stream; whereby a smokey flavor is rapidly imparted to said products by exposure of said product stream to said cloud of nebulized liquid smoke of a selected density for a selected time interval.
Claim 6
Dependent Claim 236 words
Apparatus for smoking a quantity of comestible products comprising: means for moving a stream of said products along a predetermined path of travel; enclosure means defining a smoking chamber along said path arranged to temporarily receive a portion of said product stream; means to direct a supply of liquid smoke into said chamber; means to create a moving cloud of nebulized liquid smoke within said chamber in the path of said product stream; means to control the speed of movement on said product stream along said path to thereby control the residence time of said products in said smoking chamber; inlet and outlet ports included in said enclosure for said product stream; exhaust means operative to create a negative pressure Within said enclosure lower than the pressure of the surrounding atmosphere to thereby create a negative differential pressure substantially sealing said liquid smoke cloud within said enclosure, said exhaust means including means adjacent said ports to withdraw a substantial portion of the air induced into said enclosure through said ports by said negative pressure differential, to reduce the loss of nebulized liquid smoke from said housing; and means to remove liquid smoke condensate from said chamber and said means for moving said product stream; whereby a smokey flavor is rapidly imparted to said products by exposure of said product stream to said cloud of nebulized liquid smoke of a selected density for a selected time interval.
