Energy Saving on Spray Drying Process by Modifying the Hot Air Flow

simulation, calculation and possibility of energy saving in the spray drying process

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...

Drying Macadamia Nuts by Hot Air Combined with Microwaves as Compared to the Conventional Hot Air Process

Saving Energy by Exergetic Analysis of MTP Process Refrigeration System

The exergetic analysis is a tool that has been used successfully in many studies aiming a more rational energy consumption to reduce the cost of processes. With this analysis, it is possible to perform an evaluation of the overall process, locating and quantifying the degradation of exergy. This paper applies exergy approach for analyzing the heat exchanger network design and refrigeration of M...

mathematical modeling of onion drying process using hot air dryer

the main purpose of present paper is the modeling of onion drying process and investigation of experimental data of onion drying obtained with using a hot air dryer. therefore some empirical and regression models have been considered to fit experimental data. the investigation of the experimental data shows the onion drying happens only in falling rate zone. the experimental data have been fitt...

Powder agglomeration during the spray-drying process: measurements of air properties

Instant food powders are usually produced by spray drying of formulated liquid and powder agglomeration, either into the drying chamber or in an external fluid bed. During spray drying, according to the liquid composition, the viscosity of the initial liquid drops increases more or less rapidly, until the drop surface reaches a rubbery state considered as sticky, before further drying. This sti...
