Resumo


The region of Bastos-SP is responsible for a large part of the Brazilian egg production. Many of its poultry farms produce bird feed by grinding corn and soybeans using electric engines which are often oversized. In order to analyze the use of such power, there are power (pf) and load (lf) factors that indicate its efficiency and rationality. This study aimed at developing mathematical models to evaluate a company’s power use through the volumes of solids. Such models are referred to as Load and Power Hyperboloids. It is an innovative methodology that has been in several studies on energy efficiency is always of great importance to estudados.O cases this goal was analyze these models, an egg-laying aviculture company (poultry farm) in Bastos-SP Brazil was evaluated no period de 3 anos. In this illustration, the load and power factors remained within limits [0.11, 0.21] and [0.69, 1]. For this company, the solid volume calculated with the proposed methodology was Vc  77.6 u.c. Whereas the Total Useful Volume, representing the volume in the domain with limits over 1, was Vtu  450.6 u.c., it was concluded that it is possible to improve power use by 83%, which can be achieved by applying the procedures herein proposed in order to increase pf and lf
