Construcción y prueba de un prototipo a escala de laboratorio de un secador por CO2 subcrítico con control de temperatura

Abstract

The present project consisted in the design, construction and testing of a machine, which through the use of subcritical carbon dioxide, was used to eliminate the greatest humidity found in food products. In the first instance, all the machine components were designed starting with the calculation of the pressure tanks, the clamping rods, the secondary covers and other components that intervene in the safety of the machine operator. Subsequently, the design of the machine and its plans were did through the use of SOLIDWORKS. After having schematized the machine, construction was carried out by means of the guide of the design and construction codes of the American National Institute of Standards (ANSI) and the American Society of Mechanical Engineers (ASME). Construction development were carried out in the faculty laboratories. Finally, with the built machine the tests of the established food products were carried out, obtaining as a result the percentage of mass of water extracted. A maximum extraction of sixty-six and thirty-nine percent was obtained, this value suggests that the method can be improved with the variation of the operating conditions.
