Tomato (Solanum lycopersicum) and brinjal (Solanum melongena) are food products that are frequently wasted in Indian markets as their shelf lives are only a few days. An indirect type solar dryer (ITSD) has been developed. It’s performance and drying kinetics of brinjal and tomato slices have been analyzed. The moisture content of tomato decreased from 15.667 to 0.803 kg/kg of dry basis (db) and that of brinjal reduced from 10.111 to 0.498 kg/kg of db. The drying curve was fitted with the different models of existing studies. The average effective moisture diffusivity is estimated and it is 3.60 × 10⁻⁹ and 4.00× 10⁻⁹ m²/s for tomato and brinjal, respectively. Mass transfer coefficient was in the range of 0.82 × 10⁻⁴ to 2.85 × 10⁻³ m/s for tomato and 1.11 × 10⁻⁴ to 3.32 × 10⁻³ m/s for brinjal. The heat transfer coefficient was in the range of 0.089 to 2.888 W/m² K and 0.1066 to 3.3564 W/m² K for tomato and brinjal, respectively. The activation energy for tomato and brinjal was 21.19 and 19.46 kJ/mol, respectively. The average thermal efficiency of the collector and dryer was 59.05% and 31.4% during tomato drying and 58.42% and 25.16% for brinjal drying, respectively.

番茄（Solanum lycopersicum）和茄子（Solanum melongena）是食品，在印度市场上经常被浪费，因为它们的保质期只有几天。已经开发出一种间接型太阳能干燥器（ITSD）。对茄子和番茄切片的性能和干燥动力学进行了分析。番茄的水分含量从15.667降至0.803 kg / kg干基（db），而茄子的水分含量从10.111降至0.498 kg / kg db。干燥曲线符合现有研究的不同模型。估计平均有效湿气扩散率是3.60×10 ^-9和4.00×10 ^-9  m ²/ s分别表示番茄和茄子。质量传递系数是0.82×10的范围内^-4到2.85×10 ^-3 米/秒为番茄和1.11×10 ^-4到3.32×10 ^-3 米/秒茄子。 对于番茄和茄子，传热系数分别在0.089至2.888W / m ²  K和0.1066至3.3564W / m ² K的范围内。番茄和茄子的活化能分别为21.19和19.46 kJ / mol。番茄干燥过程中收集器和干燥器的平均热效率分别为59.05％和31.4％，茄子干燥过程中的平均热效率分别为58.42％和25.16％。
