This research presents 3D steady-state simulations of a skim milk spray drying process in counter-current configuration dryer. A two-phase flow involving gas and discrete phase is modeled using the Eulerian–Lagrangian model with two-way coupling between phases. The kinetics incorporated Reaction Engineering Approach. predictions are found to be accordance experimental temperature measurements m...

spray drying is one of the most important processes applied in the industry. the equipment used in this process evaporates water in a very short time and so, need a lot of energy. in this work, we used microsoft excel as an analysis tool for the optimization of fuel usage in this dryer. we have described the process in terms of thermodynamic calculations and mass and heat balance equations. our...

In this paper, the modelling and control of the moisture content of the particles in a batch Fluidised bed dryer are studied. First, a lumped mechanistic model is developed to describe the heat and mass transfer between solid, gas and bubble phases and experimental validation shows that the model can be used to predict the particle moisture content and temperature profiles during the drying pro...

The manufacture of egg yolk powder by spray drying requires regular cleaning in order to remove fouling deposits and prevent microbiological growth on the pasteurisation heat exchanger dryer. A life cycle assessment (LCA) study a typical manufacturing plant, using literature data, indicated that breaking, storage steps were major contributors plant’s environmental impacts rather than cleaning-i...
