Definitions
- French racks can be used in a variety of dishes and are popular with chefs worldwide.
- French racks are a premium cut of meat but preparation in the past has been labour intensive requiring a skilled butcher with a knife to clear and clean the rib tips.
- the invention may broadly be said to consist in a method of preparing french racks, said method comprising the steps of positioning a prepared rib section relative to the rib ends so that the rib section is exposed to a first water jet cutting means to form a cut line in the meat, fat, collagen and membrane beyond which the rib bone ends are to be cleared and directing a second water jet cutting means in the form of a plurality of substantially parallel water jets to clear the rib ends of meat, fat, collagen and membrane with a cutting and peeling action.
- Figure 1 is a diagrammatic representation of apparatus according to the present invention
- Figure 2 is an alternative form of apparatus
- Figure 5 diagrammatically illustrates the cutting action of the present apparatus to clean the rib tips and form the french rack
- Figure 6 shows the rib section formed into the french rack being removed from the apparatus; and
- Figure 7 is an exploded view of the operating components employed in the apparatus as depicted in Figure 1.
- the apparatus for forming the french cuts is normally installed in a boning room of a freezing works or abattoir.
- the operating apparatus 1 is mounted on the boning room or other meat processing area and receives a supply of high pressure water through a line 2.
- the high pressure water is diagrammatically represented as coming from a supply line 3 through appropriate filter banks 4 and 5 and a storage tank 6 before being delivered through a high pressure pump 7 driven by an electric motor 8, all located in another area, for example a floor above.
- the apparatus 1 comprises a stainless steel casing 9 supported on a stainless steel frame and legs 10 with a slot 11 through which the rib section can be placed to be processed to form the french rack.
- the operator stands to one side of the apparatus and has a control lever 12 actuated by the knee to turn on and off the high pressure water jets used in the apparatus to process the rib section into a french rack. Waste water from the apparatus is discharged through an effluent drain 13.
- the apparatus may be produced in different configurations and an alternate configuration is illustrated in Figure 2.
- the apparatus 14 has a water supply 15 delivered under high pressure in the same manner.
- a slot 16 is provided in an inclined front face of the apparatus and in this instance the slot is associated with a carriage which will traverse the rib section being processed along the track 17 past fixed high pressure water jets which are arranged essentially in a configuration that will be explained below.
- the invention may be reduced to practice in a number of ways but it is necessary to ensure that the rib section being processed is moved past the high pressure cutting water jets either by moving the water jets relative to the rib section or by moving the rib section relative to the water jets.
- the prepared section of rib is supported on a holder 45 which is accessible through the slot 11. The relative location of the holder and water jets determines the length of the cleared section of the rib bones. This distance is adjustable.
- the meat, fat, collagen and membrane beyond the cut formed by the jets 18 is removed by a second set of high pressure water jets operating at an angle to the rib section.
- the second set of jets is delivered from a pillar 20 on one side and pillars 21 and 22 on the opposite side.
- Each pillar 20, 21 and 22 produces a plurality of parallel jets 24, with the jets operating in planes that are parallel or substantially parallel to the rib bones being cleaned but impacting the rib bones at an acute angle to remove with a clearing and peeling action the meat, fat, collagen and membrane leaving the rib ends clear.
- a rib section 25 is placed by an operator 26 into the slot 11.
- the jets 18 cut the line 27 in the meat, fat and tissue but not the bone and the plurality of jets 24 extending from the columns 20 clean the rib bone ends 28 of all or substantially all meat, fat, collagen and membrane.
- the french rack 29 so formed is then removed by the operator 26.
- the operator will place the rib section with the membrane side, that is the inner rib cage, which will be impacted by the parallel jets from the two columns 22 and 21.
- a satisfactory cleaning job may be achieved with only one column of parallel jets on each side but the speed of operation would be impaired.
- the number of jets in each column will depend upon the length of rib bone tip to be cleaned and the speed of operation. We have found that for satisfactory operation there needs to be a number of jets (from seven to 15) but this is given by way of example only and a particularly effective cleaning action over the length found normally acceptable by the market is achieved with 13 jets.
- These jets are mounted in a cut back corner of the column and comprise high pressure water jets of an acceptable design.
- the interior of the column is hollow and supplies to the jets water under high pressure. It is of course important to use a water pressure which will achieve the cleaning action as quickly as possible while not damaging the rib bones.
- the inclined action of the parallel jets cleans the bones with a cutting and peeling action and we have found that this is particularly effective both in the speed of processing achievable and the quality of the finished french rack.
- a deflector 30 is provided for nozzle 18.
- a deflector 31 is provided for nozzle 19.
- a wider deflector 32 is provided for the twin columns 21 and 22 and a deflector 33 is provided for the jets directed from column 20.
- the holder 45 is adjustably supported on adjustment screws 47 and 48 and the adjustment is made manually.
- the adjustment may be controlled by pneumatic cylinders operating to move the holder preferably between the set position to allow the apparatus to operate with two lengths of rib ends cleaned.
- a pneumatic cylinder 46 is operatively connected to reciprocate the plate 44 from which the water jets operate. Water connections are of course made to the water jets and appropriate control componentry is incorporated so that when an operator activates the lever 12 the water jets will be activated and the carriage will be reciprocated to clean the rib ends as diagrammatically illustrated in Figures 4-6. The apparatus will continue a reciprocating cycle until the operator releases the control 12 when the cleaned french rack 29 is duly processed.
- the apparatus as illustrated has been designed to form french racks from rib sections of lamb carcasses but the invention as indicated above has application to form french cuts from any animal carcass from which french racks would be required.
