Estudo de caso sobre a importância da padronização de tempo e temperatura no digestor de vísceras

Abstract

Establishments that manufacture flour and fat products for animal feed are also known as rendering plants or poultry by-product factory. Currently, they have a new meaning for their functioning. What previously had only environmental value, is now also added to economic and social issues. The companies started to provide resources to obtain expressive returns, such as the development of processes through the standardization of procedures, identifying the important and critical points of the system and concentrating efforts for control and improvement, such as the digester, a machine considered of great relevance to the production line. This case study addresses the importance of systematizing Time and Temperature in the viscera digester, with emphasis on statistical process control. Through quantitative analysis, the Shewhart Control Chart is used to prepare the Amplitude, Mean and Standard Deviation graphs. With the survey of information, through graphic analysis, it was possible to conclude the importance of standardizing the physical variables that modify the performance of the digester, since the performance of the data directly impacts the process and reflects on the quality of the product. This highlights the desirable standards for this stage of the process, according to the company, and indicates a point for improvement.
