A STUDY ON THE DESIGN, MANUFACTURING, AND TESTING OF AN AUTOMATED BOILED CHICKEN EGG PEELING MACHINE

The automated machine for peeling boiled chicken eggs with a design capacity of 500 eggs per hour was calculated, designed, and fabricated. The machine was tested using a completely randomized experimental design. The evaluated technical indicators included the egg peeling rate, egg damage rate, productivity, and electrical energy consumption. The experimental results and statistical analysis determined the operating parameters of the machine, including the distance and speed of the two shell-cracking rollers, which were Δ = 45 mm and vd = 0,83 m/s, respectively; and the clearance and speed between the peeling roller pairs, which were e = 1 mm and vb = 0,42 m/s, respectively. The egg peeling rate was 95%, the egg damage rate was less than 4,5%, the achieved machine productivity was 590 eggs per hour, and the electrical energy consumption for the peeling process was 124,3 Wh.
