poultry processors can maximise yield and ensure that their processing machinery can cater for various bird weights, from the smallest to the largest birds, entering the processing line at any time. Processing big birds weighing up to 4.3kg with- out disrupting the flow of production can be challenging. Another trend impacting the poultry processing sector is the growing market share of concept birds – an alternative to regular birds – particularly in Western Europe. An increasing number of poultry processors handle both types of birds on the same day and on the same processing lines. The differ- ence in shape and size between these birds often requires processors to make adjustments to their processing systems to achieve the best results.
Precision adjustment for each individual bird Over the last 20 or 30 years, the emphasis of breeding com- panies has been on breast meat yield and therefore eviscerat- ed yield has also increased considerably. This was in response to changes in consumer preferences for further processed items and greater demands from the food service sector. The Oxford Academic report notes that in 1962, 83% of broilers in the US were marketed as whole carcass, 15% as cut-up birds or pieces and 2% as further processed value-added items. By 2009, only 12% of broilers were marketed as whole birds, 42% as cut-up birds or pieces and 46% as further processed products. This trend has continued. A machine that offers the greatest accuracy of anatomical cuts will therefore have a tremendous impact on the yield of
deboned chicken breast fillets. When a precise anatomical cut between the two joints is achieved, there will be almost no pieces of wing joint on the griller. When required, the cut can include the maximum amount of back meat while minimising the amount of breast meat. A precise wing cut can result in more than 5g net breast meat yield.
Precision wing cutter In close cooperation with various poultry processors and to bring a solution to market that can handle birds of varying sizes – and which results in the maximum yield possible – Meyn set out to redesign its original wing cutter. The result is the next generation Meyn self-adjusting Wing Cutter High Yield Pro featuring dual circular knives with stainless-steel motors fitted within a spring coil suspension. This improved design, which is suitable for grillers of up to 4.3kg grill weight, enables the module to self-adjust to a bird weight differentia- tion of up to 1.5kg in one setting, even while running at line speeds of up to 7,500 birds per hour (15,000 birds per hour when running a double line). For the modern, high-speed poultry processor, a processing line that runs smoothly, does not require adjustments and therefore downtime and which requires minimal attention from the processor, can make all the difference. Cutting pre- cisely between the two joints, Meyn’s wing cutter leaves al- most no wing joint on the griller and results in increased yield. The poultry sector has made huge strides in improving production, but for a poultry processor to maximise yields and returns, a high quality precision tool is required.
