The main objective of the work is study process dehydration fruits and vegetables, using two different types equipment for dehydration: convective dryer, equipped with drying trays; microwave field instalation, continuous flow. In case divided products will be placed evenly on trays following specific parameters determined: initial final humidity products; air temperature; air. equipment, in a ...

BACKGROUND Hair dryers are commonly used and can cause hair damage such as roughness, dryness and loss of hair color. It is important to understand the best way to dry hair without causing damage. OBJECTIVE The study assessed changes in the ultra-structure, morphology, moisture content, and color of hair after repeated shampooing and drying with a hair dryer at a range of temperatures. METH...

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 ...

banana samples were purchased from a local market in sabzevar located at northeast of iran. then samples stored at refrigerator between 5–10oc during experiments, for prevention of chilling injury, 36 samples at three replications were prepared so as bananas were peeled and sliced with a sharp knife at three thicknesses (3, 5 and 10 mm) and then treated by three pretreatment methods (t1: chemic...

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...

The study targeted towards drying of cantaloupe slices with various thicknesses in a microwave dryer. experiments were carried out at three powers 180, 360, and 540 W 2, 4, 6 mm for drying, the weight variations determined. Artificial neural networks (ANN) adaptive neuro-fuzzy inference systems (ANFIS) exploited to investigate energy exergy indices using afore-mentioned input parameters. result...
