Simulación y diseño de un cuarto de congelación para la producción de pulpa de fruta de la empresa ASOPRUV

Abstract

The objective of this work is to simulate and design a freezing room for the production of fruit pulp of the company ASOPRUV, in order to preserve the production of two new fruit pulps of soursop and passion fruit for export. During the evaluation of the system it was found that the current refrigeration system works with ammonia and also has a compressor, a condenser and an evaporator. Based on the calculation made to establish the operating parameters, it was determined that this equipment can supply the freezing chamber to be implemented; however, it is necessary to design a refrigerant storage tank o maintain the flow of the system in case of any leakage, and to empty the system in case of maintenance. The simulation was performed with DWSIM, because it is a free software for chemical engineering applications, in order to validate the calculated data. It was determined that the calculated and simulated energies vary up to 13.38%, and the temperatures vary up to 0.17%, being these acceptable differences; the values that were calculated for the refrigeration cycle are optimal; therefore, they were used to calculate the dimensions of the ammonia storage tank. The economic analysis indicates that the project is viable with an NPV of 83248.68 and IRR of 2.3452207, analysed for periods of one year each, with an initial investment of US$1,864.6, corresponding to the costs of the storage tank. It is recommended to train the personnel on the correct use of the refrigeration chambers
