energy and exergy analyses of thin layer drying of tomato in a forced solar dryer
in this paper the energy and exergy analyses in chamber drying process of thin layer drying of tomato in a forced solar drying was investigated. the experiments were carried out with two thicknesses of 5 and 7 and two airflows 0.5 m.s-1 and 1 m.s-1. during the experimental process, ambient temperature was between 22 and 36 , air relative humidity between was 14 and 50, and solar radiation range...
متن کاملDevelopments in Solar Water Heating
Solar water heating system technology is described and the scale of the International solar water heater market is surveyed. New product developments for both direct solar water heating and solar boosted heat pump water heating are outlined. Procedures adopted by the International Standards Organisation for assessing solar water heater performance and quality are discussed.
متن کاملSolar drying of whole mint plant under natural and forced convection
Two identical prototype solar dryers (direct and indirect) having the same dimensions were used to dry whole mint. Both prototypes were operated under natural and forced convection modes. In the case of the later one the ambient air was entered the dryer with the velocity of 4.2 m s(-1). The effect of flow mode and the type of solar dryers on the drying kinetics of whole mint were investigated....
متن کاملmonitoring effective parameters of drying leafy vegetables in a forced-convection solar dryer
monitoring the effective parameters of drying crops is necessary to evaluate and determine system performance under real conditions. hence, a monitoring system was constructed to determine the performance of a vegetation forced-convection solar dryer. digital temperature sensors were set up in the air inlet and outlet of the collector and the air outlet of the drying chamber. a program was writ...
متن کاملPerformance Evaluation of a Forced Convection Solar Drier with Evacuated Tube Collector for Drying Amla
A forced convection solar drier is designed with evacuated tube collector and a blower. The performance of the designed drier is evaluated by carrying drying experiments at Thanjavur District, Tamilnadu, India with amla. Solar drying of amla is carried at different air velocity flow rates – 4m/s, 4.25m/s and 4.5m/s and is compared with natural sun drying. The temperature of the drying chamber r...
