Diseño de una cámara de congelación para la planta procesadora de pulpas de frutas de Industrias del Cerro.

Abstract

This research is aimed at designing a freezing chamber for fruit pulper factory at “Industrias del Cerro “located at San Miguel city, Bolivar province. This design is based on a mathematical model for determining the thermal load that the system must provide to freeze the finished product. Polyurethane foaming was used as an insulated because of its low thermal conductivity which was adapted for the freezing chamber and whit this, avoid heath losings. It determined a cooling cycle with a coefficient of performance whit 3.30 and the efficiency of the cycle 76.77%. The freezing chamber will have the following measurements length 3m, width 3m , and height 2m (42m3) with a capacity of 595.3 kilograms of de fruit pulp refrigeration using R-717 refrigerant which a -20℃. The sides of the freezing chamber will be made of polyurethane of 12 centimeters thick. If the factory decides to build the equipment, the factory will have the capacity to preserve their products during a longer period. It is recommended to freeze the fruit pulp because this can guarantee the requirements provided by the NTE INEN 223 7 (Ecuadorian Technical Norm) for pulps, frozen juice and nectar.
