Since ancient times, conventional techniques of food drying, such as sun have been used. Currently, drying methods developed with the latest technology to reduce damages caused by biochemical changes, which decrease nutritional value during process. Some typical used for products are solar tunnel dryer, cabinet-type etc. While this is going on, cutting-edge being created combine several produce...

A mathematical model of the coupled heat and mass transfer has been developed to calculate the drying process in a mixed-flow grain dryer. Periodical discharge operation of the dryer causes strong variations of temperature and moisture of the material. A series of quasi-stationary drying experiments have been carried out. These results are used to test and to improve the dryer model. The calcul...

This study was conducted to determine that carrot powder obtain by different drying methods (oven and vacuum-freeze dryer) of carrot unfit for human consumption that whether feed additives in animal nutrition or not. Carrots randomly divided 2 groups. First group was dried by using oven, second group was by using vacuum freeze dryer methods. Dried carrot prepared from fresh carrot was analysed ...

Rice is the main food in Indonesia. drying by using traditional method directly under sun light can require a long time to complete. The aim of this study investigate appropriate kinetics modeling rice with applied fluidized bed dryer. A 2-cm thickness has been dried at various temperatures (50℃, 60℃, and 70℃) air velocity 10 m/s from hot dryer obtained pyrolysis process. selected based on agre...

The objective of the work was to study effect drying temperature on cup quality robusta coffee subjected mechanical in comparison with conventional sun drying. processed by wet (parchment coffee) and dry (cherry methods were at different regimes (40 oC, 50 oC 60 oC) a rotary dryer. results indicated that as increased, time reduced. Sun parchment took 48 hours (approximately seven days) attain d...

Significance: Sep 30, 2002 Identified By: NRC Item Type: FIN Finding UNEXPECTED CHANGES IN UNIT 2 OPERATING PARAMETERS AND DRYER FAILURE DUE TO FLOW INDUCED VIBRATION. The failure to consider the impact of new flow induced vibration failure mechanisms on the Unit 2 steam dryer as part of the extended power uprate analysis resulted in unexpected and unpredictable changes in reactor power, reacto...

Performance of a tractor mounted solar-biomass hybrid dryer which utilise combined energy solar and biomass was investigated. Drying behaviour maize grains in the also investigated using 10 thin-layer mathematical models. The models were compared based on coefficient determination (R2) root mean square error (RMSE) values between experimental predicted moisture ratios. Moisture content (MC) red...

The photovoltaic thermal (PVT)-based solar dryer is advantageous in terms of energy-saving ability, efficiency, self-sufficient design, and ability to work without any additional electrical energy requirement. However, there a requirement for comprehensive analysis the energy, exergy, environ-economic parameters developing an efficient sustainable PVT dryer. In this study, PVT-based indirect mo...

The aim of this study was to develop a user-friendly model for spray drying that can aid in the development of a pharmaceutical product, by shifting from a trial-and-error towards a quality-by-design approach. To achieve this, a spray dryer model was developed in commercial and open source spreadsheet software. The output of the model was first fitted to the experimental output of a Büchi B-290...
