The Study of the Apple Juice Evaporation Characteristics on a Heat Pipe Evaporator

Abstract:

In this paper, the apple juice was used as the experimental medium, the main factors, such as the evaporating temperature, feed rate, temperature difference of the heat transfer and concentration, were analyzed, the heat transfer of the juice was studied on a heat pipe evaporator, a dynamic model of the apple juice during the constant volume heat process was built up, the heat transfer during evaporation, affected the heat transfer properity in evaporating process were investigated, the experimental relating formula was obtained finally. The above informations could provide some help to design new evaporators and optimize the fruit juice concentrating parameters.
