Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 237 words
Apparatus for the processing of food by means of at least smoke, comprising a housing; a partition within said housing separating the interior thereof into a distribution region and a food processing chamber; fluid circulating means mounted in said housing and having an inlet and outlet communicating with said distribution region and said food processing chamber; a door pivotably carried by said housing and sufficiently large for introduction and removal of food; means for generating smoke carried by said door for pivotal movement therewith; a first pair of conduit means carried by said housing and having one end extending therefrom outwardly of said housing, a second pair of conduit means carried by said door and having one end extending into said means for generating smoke, the other ends of said first and second pairs of conduit means being connectable on closing of said door to form two passages for the inlet of air to and the outlet of air from said smoke generating means; in said first pair of conduit means the conduit forming the air inlet passage having a section open adjacent the outlet of said fluid circulating means and the conduit forming the exhaust passage having a section open adjacent the inlet of said fluid circulating means, whereby the smoke is circulatable by said fluid circulating means from said smoke generating means through said food processing chamber and is recycled to said smoke generating means.
Claim 2
Dependent Claim 237 words
Apparatus for the processing of food by means of at least smoke, comprising a housing; a partition within said housing separating the interior thereof into a distribution region and a food processing chamber; fluid circulating means mounted in said housing and having an inlet and outlet communicating with said distribution region and said food processing chamber; a door pivotably carried by said housing and sufficiently large for introduction and removal of food; means for generating smoke carried by said door for pivotal movement therewith; a first pair of conduit means carried by said housing and having one end extending therefrom outwardly of said housing, a second pair of conduit means carried by said door and having one end extending into said means for generating smoke, the other ends of said first and second pairs of conduit means being connectable on closing of said door to form two passages for the inlet of air to and the outlet of air from said smoke generating means; in said first pair of conduit means the conduit forming the air inlet passage having a section open adjacent the outlet of said fluid circulating means and the conduit forming the exhaust passage having a section open adjacent the inlet of said fluid circulating means, whereby the smoke is circulatable by said fluid circulating means from said smoke generating means through said food processing chamber and is recycled to said smoke generating means.
Claim 3
Dependent Claim 31 words
Apparatus according to claim 1, wherein said door is hollow and a removable flap is provided whereby said means for generating smoke is accessible from the outer side of the door.
Claim 4
Dependent Claim 30 words
Apparatus according to claim 1, wherein said door is hollow and a removable flap is provided whereby said means for generating smoke is accessible from the interior of the chamber.
Claim 5
Dependent Claim 17 words
Apparatus according to claim 1, wherein said means for generating smoke is arranged exteriorly of the door.
Claim 6
Dependent Claim 19 words
Apparatus according to claim 1, wherein said means for generating smoke is arranged on the inside of the door.
Claim 7
Dependent Claim 25 words
Apparatus according to claim 5, wherein steam generating means is arranged on the inner side of the door and is accessible from the outside thereof.
Claim 8
Dependent Claim 23 words
Apparatus according to claim 1, wherein the means for generating smoke is accessible through an additional opening which is located in said door.
Claim 9
Dependent Claim 14 words
Apparatus according to claim 1, wherein the interior of said door is thermally insulated.
Claim 10
Dependent Claim 68 words
Apparatus according to claim 1, wherein said means for generating smoke comprises a smoke generator, a portion of the smoke generator including a smouldering place, a container for the smoking material being provided and connected with said smouldering place, an ash pan and an exhaust air line, said smouldering place, said container, said ash can and said exhaust air line being connected by means of disconnectable coupling means.
Claim 11
Dependent Claim 174 words
Apparatus for the processing of food by means of at least smoke, comprising a housing having a food processing chamber therein; a door pivotably carried by said housing, said door being sufficiently large for introduction and removal of food; means for generating smoke carried by said door for pivotal movement therewith; fluid circulating means carried by said door for pivotal movement therewith; first conduit means carried by said door communicating said fluid circulating means with said chamber and with said smoke generating means and second conduit means communicating said smoke generating means with said chamber, third conduit means carried by said housing in the bottom region thereof and having one end extending therefrom outwardly of said housing, said end and one of said first and second conduit means carried by said door being connectable on closing said door, the third conduit means having smoke outlets distributed along the length of the third conduit means, whereby food processing medium is recirculated from said chamber, through said fluid circulating means and is returned to said chamber.
Claim 12
Dependent Claim 174 words
Apparatus for the processing of food by means of at least smoke, comprising a housing having a food processing chamber therein; a door pivotably carried by said housing, said door being sufficiently large for introduction and removal of food; means for generating smoke carried by said door for pivotal movement therewith; fluid circulating means carried by said door for pivotal movement therewith; first conduit means carried by said door communicating said fluid circulating means with said chamber and with said smoke generating means and second conduit means communicating said smoke generating means with said chamber, third conduit means carried by said housing in the bottom region thereof and having one end extending therefrom outwardly of said housing, said end and one of said first and second conduit means carried by said door being connectable on closing said door, the third conduit means having smoke outlets distributed along the length of the third conduit means, whereby food processing medium is recirculated from said chamber, through said fluid circulating means and is returned to said chamber.
