Item Desenvolvimento de mensurador de granulometria em fábricas de rações para suínos(Universidade Brasil, 2021) Evangelista, Mariane Zabotto; Zeferino, Cynthia PieriThe objective was to develop an unprecedented particle size measurer for swine feed factory. This is because there are difficulties to get an ideal granulometry in the feed production, due absence practical technologies available inside market. The prototype was made of hardware parts (stand to collect ground grains sample, digital microscope, lighting ring, white leds, pneumatic cylinder, air compressor, microscope tube, potentiometer, solenoid valve, sphincter set and set of fasteners) and software parts (programation development with environment PyCharm Community®, version 2020.3, and the libraries Scipy®, Matplotlib®, Datetime®, Numpy®, Time®, Imutils® e Open CV®). The average geometric diameter was calculated for 02 treatments: T1 (sendding samples of 160 g ground grains to laboratory) and T2 (removal of 500 g ground grains to calculate with the prototype). LPV, IRR and simple and discounted payback was canculated for economic viability. In T1, the mean AGD found was 828,56 μm and marjority number of grains was at 500 μm gap. In T2, the mean average geometric diameter found was between 831,8 ± 124,6 μm e 1258,1 ± 445,1 μm, being these variations no significance (p≥0,05). These results suggests that measurer develop provides AGD values identification with more detailment, because it made individual read for each grain, don’t considering weight critery, what is approached in T1. LPV and IRR were positive (R$ 8.570.902,71 and 387,34%, respectively) and the simple and discount payback’s were less than 1 month. Thus, as the product doesn’t give a simple AGD average, like what is made in laboratorial methodology by density, the measurer has more details to calculation method. Moreover, the economic viability was positive, being low cost and with easy buy by farmers, commercial feed factory or machines industry.Item Desenvolvimento de mensurador de granulometria em fábricas de rações para suínos(Universidade Brasil, 2021) Evangelista, Mariane Zabotto; Zeferino, Cynthia PieriThe objective was to develop an unprecedented particle size measurer for swine feed factory.
