Developing New type of Disk Plate for Meat Chopper and its Effect to Water-Binding Capacity and Yield Stress of Minced Meat

This paper describes the construction of meat chopper with new type of perforated disk plate with variable sized holes. Cutting mechanism of meat chopper consists of knives, disk plate, rings and protracted screw-nut. Two set of cutting mechanism is used in this study: first (control) with disk plate with equal holes and the second (experimental) – disk plate with variable sized holes. Meat samples (beef, horse meat, poultry and pork) transported to the cutting mechanism by screw. Grinding process is carried out by cutting meat with four blade knife and squeezing it through disk plate with variable-sized holes. Water-binding capacity of minced meat grinded through second set of cutting mechanism showed higher values than control samples, as well as yield stress of minced meat. The obtained experimental data confirm that the process of grinding of meat can be improved by developing a cutting mechanism with new type of perforated disk plate with variable sized holes.
