  Drying is an important agricultural process, particularly for crops, and
shriveled products are used all over the world. The performance of drying green
chili was also tested in this article, which created an alternate way of drying
agricultural products. The goal of this study is to provide a solar biomass
hybrid dryer with improved design, construction, and performance testing.
During most hours of the trial, the temperature within the solar collector and
dryer was sufficiently higher than the ambient temperature, according to the
results obtained during the test period. The temperature of the ambient air at
the collector intake ranged from 30 to 35 degrees Celsius. The temperature of
the air at the collector's outlet ranged from 54 to 64 degrees Celsius, while
the temperature of the drying chamber ranged from 51 to 60 degrees Celsius,
making it suitable for drying green chili and a variety of other agricultural
products. The collector was found to be 46.54 percent efficient. The findings
revealed that the alteration of the collector, which produces turbulent air
flow and improves chamber wall insulation, affects drying. Based on the results
of this study, the created solar biomass hybrid drier is cost-effective for
small-scale crop growers in rural areas of developing countries.
