Abstract
An experimental investigation of solar-assisted heat pumpa drying mango has been conducted. A new solar-assisted heat pump drying system with a secondary heat recovery was setup, which can operate ...
Highlights
Drying process is an energetic intensive activity and plays a significant role in many industrial applications such as food, textile, paper, and in many other processing industries (Abdulmalek et al, 2018)
An indirect forced convection solar dryer has been presented for drying mango; the solar dryer could attain an average thermal efficiency between 30.9 and 33.8% with the drying air temperature of 52C (Wang et al, 2018)
A solar distillation cum drying unit with parabolic reflector was made and heat transfer coefficients were evaluated by experimental analysis (Manchanda and Kumar, 2017)
Summary
Drying process is an energetic intensive activity and plays a significant role in many industrial applications such as food, textile, paper, and in many other processing industries (Abdulmalek et al, 2018). Solar energy has been considered as one of the main heat sources employed to reduce the conventional energy consumption for the drying process. A solar distillation cum drying unit with parabolic reflector was made and heat transfer coefficients were evaluated by experimental analysis (Manchanda and Kumar, 2017). A solar dryer comprising of two different solar collectors was developed, which used an air-type solar collector with an area of 12 m2 for direct heating and a flat-plate type solar collector for the accumulation of converted heat energy (C ipliene et al, 2015), by combining operation of two different solar collectors, the solar irradiance variability could be compensated and the stability of the drying process could be ensured
