Abstract
Abstract Ways and means are provided for destroying odorous components of gases released from garbage and food waste byproduct processing plants during receiving, storage and processing operations. Destruction is accomplished by collecting all such odorous gases and cycling them through a high temperature region, raising them to an odor-destroying temperature, of e.g. 1300* F., before releasing them to the atmosphere. Where wet composted material is to be dried in the plant, some of the gases are utilized in a direct contact dryer. The gases utilized in the dryer are preheated by indirect heat exchange with the deodorized gases, thus lowering the temperature of the exhausted, deodorized gases, to e.g. 600* F.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
27 words
The apparatus of claim 1 wherein said valve operator means is further connected to the first-mentioned valve means for coordinate operation thereof with the last-mentioned valve means.
Claim 2
Dependent Claim
17 words
The apparatus of claim 1 wherein said withdrawing means and said separating means comprise a cyclone separator.
Claim 3
Dependent Claim
47 words
The apparatus of claim 1 wherein said fifth conduit means terminates exteriorly of said combustion chamber in means defining a duct proceeding at least partially circumferentially of said combustion chamber, means defining a plurality of angularly spaced, spirally proceeding openings into said combustion chamber from said duct.
Claim 4
Dependent Claim
89 words
The apparatus of claim 1 further including: storage enclosure means for receiving the dried biological material; enclosed conveyor means for transferring the dried biological material from said centrifugal separating means to said storage enclosure; an exhaust pump having a pressure side and a suction side; conduit means communicating the suction side of said exhaust pump with said storage enclosure means for maintaining at least slightly lower than atmospheric pressure therein; conduit means communicating the pressuRe side of said exhaust pump with the first side of said indirect heat exchanger.
Claim 5
Dependent Claim
94 words
The apparatus of claim 1 further including: means defining a wet biological material processing room; enclosed conveyor means for transferring the wet biological material from said processing room to said conduit means for adding wet biological material to said dryer; an exhaust pump having a pressure side and a suction side; conduit means communicating the suction side of said exhaust pump with said processing room for maintaining at least slightly lower than atmospheric pressure therein; conduit means communicating the pressure side of said exhaust pump with the first side of said indirect heat exchanger.
Claim 6
Dependent Claim
108 words
The apparatus of claim 6 further including means defining an enclosed truck lock adjoining said processing room and sharing a common wall therewith; means defining at least one truck receiving opening into said truck lock; means defining at least one opening through said common wall; door means for both said openings, whereby at least one truck containing wet biological material for processing may enter said truck lock and be enclosed therein by closing the door of said truck receiving opening and said door of said opening in said common wall may then be opened for transfer of said wet biological material from the truck into the processing room.
