ABSTRACT:
This invention increases the yield of output shrimp meat produced by roller type peeler apparatus, and achieves this without any substantial decreases in throughout quantity. The yield increase is achieved by means of critical interacting operating relationships in the peeling action between power rollers, intermediate rollers and insert rollers, expressed in terms of relative roller diameters. Preferred sets of rollers are identified that significantly increase the yields of cold water Pandalus species of shrimp in sizes of 90/kg to 350/kg over conventional commercial rollers. Surprisingly, the high throughput quantity of the peelers is not seriously compromised and may be even increased by the ability to provide more peeling channels in a conventional size peeling tray by replacement with smaller diameter power rollers. The preferred roller sets for use in current standard commercial equipment, without other changes, has lower power rollers of 2.5 inch (6.4 cm) diameter, intermediate upper channel forming rollers of 2 inch (5 cm) diameter and insert rollers of 7/16 inch (1.1 cm) diameter. The methods of establishing critical roller diameters provided by this invention will permit adaption of the feature of obtaining highest yields feasible with critical roller diameter selections for various conditions encountered in the shrimp peeling industry ar at a particular peeling site, including product variations from different shrimp catches, sizes, species, etc.
