The objective of this research is to create a system that can dry grapes more effectively than sun drying with electricity or natural drying methods while simultaneously comparing their drying features. Procedures and materials: Everything is running well at the moment thanks to solar plates, an LCD screen, a charger controller, a temperature indicator, a battery, etc. The grape samples are dried in a solar drier to check their moisture content, drying rate, and drying time. In this study, 20 samples were used for the control group that used the natural drying technique, and 20 samples were used for the experimental group that used the solar drying approach. Using the criteria used to determine the drying rate of grapes, a total of 40 samples were examined, with 20 samples each group. With a 95% alpha of 0.05 and a confidence level of 80%, the G power formula was used to determine the sample size. The results showed that the natural drying approach dried the grapes at a rate of 38% for the 12gm sample, whereas the solar drying method dried them at a rate of 41%. Natural drying yielded a drying rate of 10.3960 percent, whereas solar drying produced a drying rate of 18.6765 percent. There is a statistically significant difference (p=0.001) between the two groups when it comes to sunlight drying and open sun drying. The two groups' significance values are p=0.001 (p≤0.05). This is a discrepancy with strong statistical support. The results showed that a newly constructed solar dryer performed admirably when tested with grapes. A comparison research was conducted to investigate the drying capabilities of carrots using both natural and solar drier approaches. There was a statistically significant difference between the two groups when it came to drying the carrot samples. [ABSTRACT FROM AUTHOR] |
