Grapes Drying: An Indigenous Profitable Enterprise in Balochistan

Drying Kinetics of Muscat Grapes in a Solar Drier with Evacuated Tube Collector

A solar drier assisted with evacuated tube collector is designed and developed to study and examine the drying Kinetics of muscat grapes in Thanjavur, Tamilnadu, India.  During the drying period, temperature at various places, relative humidity, wind velocity and mass of the sample are measured on hourly basis.  The outlet temperature of the collector and temperature within the chamber varies f...

A Rational and Profitable Way of Artificial Drying Artificial Drying of Agricultural Products at a High Level of Quality

Towards an Early Profitable PowerSat

For initial development of almost anything, small systems are preferred over large for obvious reasons. Unfortunately, development of space solar power (SSP) suffers from the extremely large dimensions and mass of traditional designs making small scale tests and initial operations difficult. So difficult that SSP is perceived to be orders of magnitude away from profitability, requiring new laun...

evaluation of microwave and convective finish drying parameters and drying effects on color of dried grapes

in this study, the possibility of microwave finish drying for two types of dried grapes (natural and sultana) was investigated. the samples were washed in water bath at given temperature ranges (25 and 45 c) for 30 to 60 minutes. after dewatering the samples, they were dried using microwave (at two powers: 270 and 450 w) and hot air convective dryer (at 50 c). water gain (%), effective moistu...

Fixed and Incremental Levels of Microwave Power Application on Drying Grapes under Vacuum

Microwave vacuum drying has been investigated as promising potential for high-quality dried fruits. In this study, a batch microwave vacuum dryer was used to understand the effect of levels of microwave power on the drying characteristics and moisture content of grapes. Thompson seedless grapes were treated 1st for 30, 60, and 90 min at fixed levels of 500, 750, 1000, 1250, and 1500 W at a redu...
