Determining the cause of deviation in feed systems soft drinks applying Pareto methods.

One of the most important standards approaching process quality is ISO 9001, which is based on 8 principles. Therefore, the measurement, testing, analysis, and process capability basis are usually used for assessment of the achieved quality level, and can be utilized for improvement of processes and products quality. This paper presents the essence and significance of the process approach and methodology of testing, analysis and assessment process as the basic assumptions in quality improvement process. The emphasis is on basic indicators of process capability index potential (scatter) and ability (adjustment) process. Using the software package QI Macros, quality index of the production process of non-alcoholic carbonated beverages in serial production is determined. Our aim was to shown the need of applying the Pareto analysis, quality system statistical tool for ranking the errors that lead to deviations in the system of soft drink “Orangina” filling, and to make recommendations an implementation of corrective actions based on the indices are priorities. The main objectives of the work was to determine the causes of deviations in soft drink filling system with different groups of samples (filling of 0.5, 1.0, 1.25 and 1.5 liters), and to establish whether application of recognized methods for determination of level of process control (calculating the index of resources (Cp) and capability indices (Cpk)) can determine whether the whole process is under control. Examined processes of filling in the brewery were working on 3 sigma level. The results showed that the maximum deviation occurs when the group of samples with a volume of 1.5 liters are filling. On the other hand, a group of samples of 0.5 liters showed the most accurate and statistically the most appropriate index values Cp and Cpk. Pareto method proved that the four groups of causes (needles soaking juice, heating with blowers bottle, the pressure in the carousel and calibration) cause the greatest number of defects (78.1%).
