The improvement of the apparatus used to obtain certain high quality products in food industry, cased by the development of the synthesis processes in the last few years, brought about the working out of calculations more and more complex as far as their technological dimensioning is concerned. One of these is the agitated film evaporator, which, due to its performances, has gained more and more ground lately. The purpose of thy present work is to offer calculating program of the main technological dimensions realized according to a mathematical model that takes into account the physical proprieties of the mixture that undergoes the evaporation in order to simplify the dimensioning work of these apparatus.
