Abstract

Abstract A system is provided for injecting slaughtered animal carcasses with tenderizing solution. The carcasses to be injected are weighed and are conveyed to a plurality of sequential injection stations. A number of injection headers are energized for calculated energization time periods. Each carcass is injected by each injection header with solution that flows automatically for a calculated time period that is directly proportional to the carcass weight. A microprocessor is utilized to provide a separate data storage location for each injection station. Data is provided to each storage location in proper sequence as the side to be injected is conveyed to sequential injection stations. A separate timing means is provided for each injection station, and data from the storage location is transferred to the timing means in sequence as the carcass to be injected is conveyed to sequential injection stations. The microprocessor is also utilized to generate a display that is used to monitor the output and internal performance of the injection system with regard to weight data sequential transfer and also injection count number information. An alarm status condition is generated if the system performance is not in compliance with internal standards.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 182 words
A system for injecting slaughtered carcasses with tenderizing solution, in which the carcasses to be injected are weighed and are conveyed to a plurality of sequential injection stations, the improvement comprising, in combination: at least one injection header located at each injection station; means for providing injection solution to each header; storage means for storing weight data for each injection station; means for providing weight data to said storage means, in sequence corresponding to the injection station sequence, whereby different carcasses may be at each of the plurality of stations at the same time and each carcass will be tracked as it is conveyed to each successive station and the weight data in a storage location for the respective station will correspond to the carcass at the respective station; means for providing energization time periods that are directly proportional to the carcass weight; and means for energizing the injection headers for calculated energization time periods whereby each carcass is injected by each injection header with solution that flows automatically for said calculated time period that is directly proportional to the carcass weight.
Claim 2
Independent Claim 182 words
A system for injecting slaughtered carcasses with tenderizing solution, in which the carcasses to be injected are weighed and are conveyed to a plurality of sequential injection stations, the improvement comprising, in combination: at least one injection header located at each injection station; means for providing injection solution to each header; storage means for storing weight data for each injection station; means for providing weight data to said storage means, in sequence corresponding to the injection station sequence, whereby different carcasses may be at each of the plurality of stations at the same time and each carcass will be tracked as it is conveyed to each successive station and the weight data in a storage location for the respective station will correspond to the carcass at the respective station; means for providing energization time periods that are directly proportional to the carcass weight; and means for energizing the injection headers for calculated energization time periods whereby each carcass is injected by each injection header with solution that flows automatically for said calculated time period that is directly proportional to the carcass weight.
Claim 3
Dependent Claim 35 words
A system for injecting carcasses as described in claim 1, including a plurality of injection headers located at each injection station, and means for counting the number of injections which occur at each injection station.
Claim 4
Dependent Claim 25 words
A system for injecting carcasses as described in claim 2, including means for displaying the number of injections which have occurred at each injection station.
Claim 5
Dependent Claim 46 words
A system for injecting carcasses as described in claim 1, including a separated timing means for each injection station, and means for providing data from said storage locations to said timing means in sequence as the carcass to be injected is conveyed to sequential injection stations.
Claim 6
Dependent Claim 35 words
A system for injecting carcasses as described in claim 4, wherein each of said timing means comprises a down counter; and an oscillator for counting down said down counters to provide calculated energization time periods.
