This research aimed to examine the need of adding hot water blanching pre-treatment on drying ginger rhizomes using a hybrid solar-dryer with paraffin liquid as thermal storage infused into copper tube form compact heat exchanger. Blanching duration quickened rate and average for at 90 s, 60 30 s un-blanched varied between 0.0147 kg/h 0.0245 sensible ratio 4.12 × 10-5 2.53 10-3. The optimal from 0.01161 0.0263 all treatment collector temperature range 39.5 °C-40.5 °C efficiency 14.3%-30%....
This study presents the effect of loading on heat transfer rate and specific water consumption detached loosed fresh palm fruits during sterilization. Sterilization is an integral process oil extraction that consumes a lot water. However, most industrial research in past focused fruit bunch (FFB) sterilization dynamics. At same time, medium- small-scale industries sterilize already (LFPF) have been removed from spikelet as purchased aggregators. Therefore, data generated FFB might not be...

The study investigates influence methods Andropogon tectorum (Gamba grass) Pennisetum puerperium (Elephant forage used hay...
This study evaluates a solar PV-powered evaporative cooling system for vegetable cooling. The features dual chambers with two different biomass pads, operating at temperatures. To assess its potential, the research examines evolution of temperature and humidity chamber, effectiveness, capacity, coefficient performance (COP), energy metrics, greenhouse gas emissions, overall cost. results show that achieved depression range 0.22 to 5.2 °C 0.57 10.94 wood shavings polyurethane foam,...
Experimental evaluation of the tribological performance boron steel ploughshare used for soil tillage operation has been studied under dry sliding contact. A ball-on-disc properties test was performed following ASTM standards. Surface morphology examination sample using optical microscopy. The effect applied load, speed, and time on analyzed. Results showed that with increasing load from 2 to 10N, friction material operated within boundaries 0.232≤µ≤0.325, 0.283≤µ≤0.378, 0.308≤µ≤0.381,...
The effects of surface texturing on the tribomechanical properties epoxy composites reinforced with chemically activated carbon were studied. Activated produced from palm kernel (PKSAC) and coconut shells (CSAC) composed in three concentrations (XCSAC): 100 vol. % CSAC + 0 PKSAC, 50 PKSAC particle sizes (XPS): 60, 105 150 μm, reinforcement amounts (XRW): 4, 6 8 wt. %, used to fabricate cylindrical discs Ø × mm height four texture geometries. epoxy/activated experimentally evaluated for...
Epoxy/activated carbon composites of particle sizes (60, 105, 150μm) and reinforcement weight percentages (2, 4, 6 8) have been developed evaluated for engineering applications. The physicomechanical properties were determined according to ASTM standard methods. Density decreased with an increase in percentage. 2% increment the chemically activated fillers yielded tensile flexural strengths higher than that selected commercial brake pads (CB1) (CB2), strength 4.84 6.58MPa, 12.84 21.61MPa...
