SOLAR ENERGY – AN ENERGETIC SOURCE FOR THE VEGETABLE AND FRUIT PRODUCTS DRYING IN BRASOV AREA

Abstract

The dried vegetables and fruits can have multiple usages, if they keep much better their food and commercial features. For drying process an important amount of energy is consumed. In the paper is analyzed the possibility of the solar energy use for drying those products, with the condition that the process of water evacuation to be rigorous checked up, without damaging the nutritious elements which they contain. In Romania the method is recommended for the south and east zones where the solar radiation intensity is bigger, and the vegetables and fruits have an important weight in the agricultural production. The heat needfulness for drying it can be assumed with solar panels, and the energy for the fans with photovoltaic panels.
