RESEARCH ON THE IMPORTANCE OF USE VENTILATION FOR DRYING TOMATOES, CARROTS AND APRICOTS

Abstract

In this paper is presented the importance of using a ventilation system during drying plant products, in this case for tomatoes, carrots and apricots. In all drying equipments the ventilation system plays a very important role because it keeps constant the drying temperature, ensure the uniform spread of the drying agent throughout the drying chamber and also helps to evacuate the excess water from the drying chamber, increasing the process efficiency. For tomatoes, carrots and apricots the use of a ventilation system is very important because the initial water moisture of this products is high enough, it varies between 85...90%, while the storage humidity can not be over 12...14%. To achieve this is necessary to use a very good ventilation system, to ensure the evacuation of water vapors from the drying chamber, especially because the drying temperature is relatively low and there is the risk of molding products because of the high level of humidity in the interior of drying chamber.
