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...
متن کاملefficient solar air heater with perforated absorber for crop drying
outdoor experiments on a once-through single glazed solar air heater with perforated metal absorber plate were conducted to determine the practical effect of absorber plate porosity as well as suction air flow rate on the collector thermal efficiency and its total pressure drop. three aluminum absorber plates were made perforated by drilling circular holes with different diameter/pitch ratios i...
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...
متن کاملOperational trends of a mini parabolic solar collector for agricultural purposes in a non-active solar environment
The mode of operation of mini parabolic solar panels made of germanium, mild steel and aluminium were investigated experimentally, as means of providing heated water on a farmland; the process was also modelled. Angular adjustments of the solar collectors from 70-90o were adopted in order to determine, the best material of construction for the parabolic solar collector and the angular orientati...
متن کاملInterconnected Heat Pipe Solar Collector
This paper deals with the performance of a heat pipe solar collector. The solar collector consisted of an interconnected heat pipe so as to reduce the production cost by using an interconnected heat pipe because all the heat pipes can be evacuated, sealed and tested at once. Performance of a prototype of the heat pipe solar collector was experimentally examined, and the results were compared wi...
