Diseño de una máquina mezcladora horizontal helicoidal de materias primas para la obtención de balanceado avícola con capacidad de 100 kg/h

Abstract

The research focuses on the mechanical design of a horizontal mixer for poultry feed production, with an operating capacity of 100 kg/h. The design considers geometric, mechanical, and material strength criteria, selecting AISI 304 stainless steel due to its compatibility with the food industry. The dimensions of the container, mixing shaft, and propellers are calculated, and the torque, power requirements, and motor selection are estimated. In addition, a structural analysis of the shaft under combined bending and torsion loads is performed, applying fatigue design criteria using the modified Goodman method, in order to ensure an adequate safety factor during operation. Finally, the optimal shaft diameter is obtained and construction parameters are established to ensure efficient, safe, and reliable operation of the equipment.
