This paper is attempt to utilize the solar radiation in a dryer for saving day-light, energy, and environment. Solar was designed based on thermal analysis heat transfer equations, then it constructed tested Thailand (on latitude 14 ° N. longitude of 100 E). The main three stages were carried out order test performance. Initially, energy consumption data recorded from 8:00 a.m. 5:00 p.m., witho...

This paper presents a kinetic study of solar dehydrated mint (Mentha spicata L.) with no prior treatment. The drying kinetics leaves dried in Domestic Solar Dryer terms colour attribute, moisture content, time, non enzymatic browning, water activity, rehydration ratio were calculated. is very useful for household scale to optimize process and achieve superior quality product at home maintaining...

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 ...

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...

This study is aimed at investigating the moisture sorption behavior and thin-layer drying kinetics of local sweet potato sada (LSPS) variety slices. The tubers were sliced 3, 5, 7 mm dried temperatures 45, 55, 62°C a constant air velocity 0.6 m/sec in laboratory-scale cabinet dryer. BET (Brunauer, Emmet, Teller) GAB (Guggenheim-Anderson-De Bore) models applied to fit data. Fick’s diffusion equa...

The development of a low temperature storage cabinet for the preservation of viruses and other infectious agents some years ago (Horsfall, 1940) led to the use of similar solid C02 cabinets in numerous laboratories. The original cabinet has been in continuous operation for more than 11 years, and others more or less like it have been operating for almost as long. Despite the generally satisfact...

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...
