Kinetics of osmotic solution regeneration in the evaporator IUR 20

Abstract

A team of researchers from the Faculty of Agriculture in Novi Sad designed an original device for the regeneration of osmotic solution used in the process of osmotic drying. The effects of two types of ceramic (porcelain) fillings and air temperature on the regeneration process were studied. On the basis of Fisher's criterion, it was concluded that air temperature affects the specific energy consumption for a probability of 95%. Moreover, it was also concluded (on the basis of Fisher's criterion and for a probability of 95 %) that a type of a porcelain filler has no impact on the specific energy consumption. In addition, a mathematical model of the functional dependence of regeneration kinetics on regeneration temperature and duration was also established. The regression analysis resulted in the functional dependence of regeneration kinetics and energy efficiency on the air temperature and the type of examined fillers.
