Diseño, construcción y automatización de una mezcladora de sales minerales para la estación experimnetal tunshi.

Abstract

A mixer of mineral salts made in the Balanced Specialized Laboratory was designed, built and automated, in the Tunshi Experimental Station, belonging to the Faculty of Animal Science, ESPOCH, located in kilometer 12 of the Riobamba-Licto road way, Riobamba Canton, Chimborazo Province. Using descriptive research for the design, construction and automation of the mixer; once the machine is installed, we carry out functional tests; trough samples sent to the laboratory we determined the distribution of sulfur levels mg/kg, in different segments of the mixing machine, with five repetitions for each treatment analyzed under a completely random design, after having used the tukey test (p≤ 0,05) and (p≤0,01) it was observed that the best mixing time with 200 kilograms of mineral salts was 20 minutes, there being no statistical differences (p> 0,05) in the tree segments, with the segment close to the hopper 4900 mg/kg, the middle segment a value of 5020 mg/kg the segment close to the engine 5140 mg/kg. It was concluded that the homogeneity of the mineral mixture is related to the mixing time, demonstrating an efficiency of 99,98% and a waste of 0,01% of the mixer. It was recommending 20 minutes as the optimum time for mixing mineral salts for the supply to all zootechnical species, disseminating this type of research to small and medium livestock productions.
