Aplicação de ferramentas da qualidade no desenvolvimento de um biorreator secador solar para estudos de cinética de secagem

Abstract

The fruit processing industries generate wastes whose use has been the subject of recent research, showing the viability of the protein enrichment cell growth of microorganisms using semisolid fermentation techniques, aimed at obtaining supplements for animal and human consumption. This study aimed to apply quality tools in order to improve the drying kinetics of pineapple husks, enriched using Saccharomyces cerevisiae as the inoculum. The procedure was divided into two stages. The first consisted of the protein enrichment of the substrate for 24 hours at relative humidity of 40%, using an inoculation of 2% corresponding to 300g of the substrate. The next step was determined by drying the mixture. Both steps were performed in a bioreactor solar dryer. The analysis reveals that the drying time was not enough to obtain the desired moisture, making an expert inspection on the causes that led to the failure of the procedure through quality tools.
