Theoretical Research on the Thermal Calculation of the Convective Drying Installations for Vegetables and Fruits

Abstract

The paper presents an algorithm for the thermal calculation of a convective-drying installation for vegetables and fruits. Starting from the functional scheme of the drying installation, at first, the chosen or imposed input or output data are specified, thereupon the mathematical modeling of the moisture balance, of the theoretical thermal balance for the drying chamber, and of the specific heat consumption is made. Next, the calculation model of the real thermal balance, of the incoming and outgoing energies of the system is specified; and the equation of the general thermal balance of the convective drying process of vegetables and fruits in the aforementioned installation is established. In the end, an efficiency calculation of the energy use in the drying installation is made. These instructions are formulated for presenting the template used for editing the articles for the scientific journal Bulletin of the Transilvania University of Braşov. The material presents the camera-ready form of the articles. The abstract should synthetically outline all the pertinent results, in a short but intelligible form. The abstract should begin by clearly stating the purpose of the paper and should end by formulating the most important conclusions. There will be used short, direct, and complete sentences, written in a single paragraph, without “tab” -s. The abstract will have 7...10 lines.
