Improving Heat Transfer in Falling Film Evaporators in Food Industries
Falling film evaporators, due to their high heat transfer coefficients, low energy loss, rather a low holdup time, and the ability to handle high capacities have broad applications in food industries. Thus, this kind of evaporator is being used in the production of temperature sensitive compounds such as syrups. In this study, through modelling of the falling film evaporator with the use of...
متن کاملHeat Transfer Coefficient Correlations for Robert Juice Evaporators
CORRELATIONS FOR heat transfer performance in sugar factory juice evaporators are important for benchmarking and prediction of evaporator set performance. The correlation recently proposed by Broadfoot and Dunn (2007) (B&D) is examined and comparisons are made between it and formulae currently being used, in particular with the ‘Australian typical’ correlation, using data from Australian and ov...
متن کاملHeat Transfer, Mass Transfer and Scaling Characteristics in a Long Tube, Climbing Film, Pilot Plant Evaporator
ing characteristics could be investigated. Finally the pilot plant A single tube plant Kestner evaporator'was set up at was run under 1st effect conditions in order that a comparison Illovo to investigate heat transfer characteristics when could be made with industrial 1st effect evaporators (both simulating different evaporator Tests carried out have Roberts and Kestner). This particular trial...
متن کاملSome Data on Heat Transfer in Multiple Effect Evaporators
Heat transfer data from measurements covering 15 Roberts evaporator vessels at 3 mills (82 data sets total) is presented. Heat transfer coefficient (HTC) is plotted against brix, temperature, temperature difference ( At) and viscosity respectively. It is shown that the influnce of At on HTC cannot be deduced from this type of data. The pronounced difference in operating conditions between last ...
متن کاملAverage Heat Transfer Coefficient in Rectangular Ducts with Baffle Blockages
An experimental investigation was conducted to study the average and the fully-developed heat (mass) transfer coefficients in a rectangular smooth duct and a duct with repeated-baffle blockages. The focus of attention in this work is the conventional correlation Nu / Nufd 1 + C / ( X / D ) for the average heat transfer coefficient. It was shown that for relatively short ducts, the coefficient C...
