Diseño de un molino tipo picadora para la molienda de carnes y productos afines, destinado al área de alimentos del CESTTA-ESPOCH

Abstract

The research is the design of a grinder type mill to grind meats and related products for the Food Area of the Center for Technical Services and Environmental Technology Transfer (CESTTA) of the Faculty of Sciences of the Polytechnic School of Chimborazo. With an experimental method used for being a factual research of applied type with a non-determined population, the simulation of grinding was carried out in a meat mill model 100-22 Pigor, 110 Volts rough motor with three speeds, using two samples at different times and revolutions, obtaining a record with variables (weight vs. time), and parameters that intervene in the process, the optimum design conditions were observed. The equipment has a capacity of 68kg/h, with a screw conveyor that acts by turning its propellers to transport material to the blades and grid where it defines the size, the mill works at 80 rpm measuring 45 cm high x 22 cm wide x 34 cm long, where the motor will be with a capacity of 0.5 HP at 110V, being optimal operating conditions, giving us a homogeneous sample of 3 mm particle with 90% reduction. We conclude that the mill is designed for optimum operation based on physical characteristics such as hardness, specific weight and dimensions required by the meat sample for subsequent bromatological analysis in the CESTTA laboratory. We recommend the equipment manufacturer to take into consideration a construction so that the equipment can be easily disassembled for cleaning at the end of each operation.
