Diseño de la cadena de frío post-cosecha para conservar rosas de exportación: diseño del cuarto de preenfriamiento para remover calor de campo del producto florícola.

Abstract

The present work intends to contribute to the improvement of energy efficiency and thermal performance in pre cooling chambers used in post-harvest for the reduction of harvest temperature and conservation of export roses, commonly used by SMEs whose business is floriculture. In general, with the purpose that the efficiency and performance of the refrigerated conservation system are complemented with the quality for the export of roses, an analysis of the behavior of the chamber is carried out, thus verifying and validating the internal conditions together with the construction parameters. commercials of this. For the analysis of the proposed behavior, a transient three-dimensional model of computational fluid dynamics (CFD) is developed, which models the effect of the speed of the air flow inside the chamber on the temperature distribution of the roses in the pre-cooling by forced convection at different points in the chamber.
