Food Dryer Design and Analysis of Velocity and Temperature Profiles

摘要

The chamber of a hot air dryer is the most important zone within the process of moisture extraction focused in food. Because of this, it is necessarily make a control of its variables for guarantee the homogeneity in velocity and temperature. For this, is possible identify how are the contours within a simulate environment using CFD methods and with this, modify the necessary for improve the performance of the system. According with that, in this work was made a design of a hot-air dehydration system focused in food, proposing different configuration of the trays and position of the inlets an outlets of air flux. With these designs were made the analysis of the contours of temperature and velocity from the CFD simulations made in the tool Flow simulation of the Solidworks software. With this, it was found that the geometry that guarantee uniformity in the average value of the velocity and temperature in the chamber, is a system with outlets in both sides and horizontal trays.
