Abstract
In the food sector, the packaging process of manufactured products represents a critical stage of production. In the manufacture of products in the form of powders such as flours and spices, this stage becomes more delicate due to the great tendency of failures and leaks, compromising quality, plant safety and productivity. In this case, the behavior of equipment failures can become unpredictable, making maintenance planning difficult, and consequently causing significant production losses, as well as unforeseen maintenance costs. In order to permit the prediction of the behavior of this type of process, the use of the equipment reliability analysis methodology becomes a strategic tool for maintenance management, allowing the forecast of the average time between stops, the risk analysis and facilitating the decision-making. Combined with this method, it is possible to use other strategic maintenance management tools, such as Reliability Centered Maintenance (RCM), Failure Mode and Effect Analysis (FMEA), and failure tree analysis (FTA). The aim of this work is to present a case study of a powder product packaging line, using the reliability engineering technique for analyzing the performance of the equipment. Data related to the maintenance activities of a company from the food sector were used. The packing line was composed of 15 machines with the capacity of packaging weights between 10g to 250g. Due to confidentiality, data relating to the company, model and brand of equipment, will be kept confidential. Weibull distribution function will be used for probabilistic analysis using the Excel software. After a study of the critical equipment of this line, the analysis of its failure tree will be carried out in order to identify the failure mechanisms of the equipment, in order to seek an optimization of the components with less functional performance. In addition, a plan of actions will be proposed to work on the four main root causes of failure to reduce the high rate of unplanned corrective maintenance events.
