The performance evaluation of Mixed-Mode Passive Solar Dryer for drying codfish (Gadusmorhua) was conducted. dryer is comprised among other things, materials sensible heat storage to discharge during the off-sunshine period. chamber integrated with a suction device aid convective airflow avoid reversible reaction accumulated moisture. solar evaluated fresh samples at initial moisture content 79...

The paper deals with the block-oriented approach in modelling of a solar domestic hot water system. Due to the linking possibility to other technological processes (greenhouse, dryer, etc.) the Matlab+Simulink software was decided to use. The entire model consists of the sub-system models as collector, heat exchanger and storage tank. The governing heat and mass transfer equations are given alo...

This paper presents the design, construction of an IoT greenhouse solar dryer for semi-dried jerky. In dryer, heated air is controlled automatically by based system, and at same time, absorbs energy directly through polycarbonate transparent walls roof. The results showed that was a good jerky after drying into ensured food safety with non-detected total aerobic organisms, heavy metal, bacteria...

In this study, coriander leaves were subjected to three different drying techniques; direct sun, shade, and using an indirect solar dryer. the developed dryer, hot air obtained from a black-body collector was pushed by blower powered panel, sent chamber with multiple trays for thin-layer drying. Experiments conducted summer winter seasons, temperature relative humidity variations in measured da...

This paper proposes an indirect-mode forced convection solar dryer equipped with a PV/T air collector. The collector generates both heated and electrical energy, which are used to force in the dryer. Experiments were carried out on selected tomato slices for temperature humidity readings as well masses of dried samples instantaneously recorded two days. A thermal analysis was performed drying s...
