“…Furthermore, they are chemically stable and do not degrade over time, making them suitable for long-term storage applications. Additionally, paraffin wax-based organic PCMs are relatively inexpensive compared to other PCM options, which can make them an attractive choice for certain applications [69].…”

The most recent developments in the use of phase change materials (PCM) in solar dryers around the globe are summarised in this review article. The article emphasises the benefits of utilising PCM in solar dryers, including enhanced thermal performance and accelerated agricultural product drying. The review discusses the various PCM kinds and their characteristics, as well as the various arrangements of solar dryers that use PCM. The difficulties and restrictions of employing PCM in solar dryers are also covered in the study, including the need for careful PCM integration and selection as well as the complexity of PCM modelling. Overall, the study offers a thorough summary of the status of research on PCM-based solar dryers and offers insights into potential future research areas.

“…[29] and Abedini et al [30], studied deep bed drying performance on paddy and shrimp respectively, using hybrid infrared-solar dryer and found it to be more effective than solar dryer only. Using an organic paraffin wax, with a melting point of 60 ℃ as phase change material (PCM) in a solar dryer chamber with black stones as the base, Radhakrishnan et al, [31] dried coconut from an initial moisture content of 55.5% to a final moisture content of about 9%, observing that the drying time of coconut decreased by about 28 and 52 h on using 100 g and 200 g of PCM, respectively, compared to open sun drying; the sensory characteristics like colour, taste, flavour, quality, and texture of the dried coconut sample were superior to the sun-dried coconut sample. Senthil et al, [32] also found the integration of PMC in the solar dryer to enhance drying and reduced drying time up to 60% over a solar dryer without PCM.…”

A chimney dependent solar crop dryer (CDSCD) was designed and developed. Design of Experiments (DOE) was used to carry out experiments using a statistical three level non randomized factorial experimental design in Minitab statistical software version 19.0. The effect of three drying parameters, roof angle (º), Inlet gap size (mm), and time (h) on dryer inlet mass flow rate (kg/s) and moisture content (%) were studied. The regression results showed that there was a satisfactory fit of the model variability for both dryer inlet mass flow rate and crop moisture content. The p-value for each parameter was less than 0.005, which is statistically significant. The R-squared (R2) value was 94.67% for inlet air mass flow rate study and 99.72% for moisture content. It was observed that the optimal values for achieving a low moisture content response (≤ 24%) were roof angle of 81º, inlet to outlet cross-sectional area ratio of 1.08768:1 and a minimum drying time of 24 hours while the optimal values for achieving high inlet air mass flow rate (≥ 0.357 kg/s) were roof angle of 51º, inlet to outlet cross-sectional area ratio of 1.08768:1 and a minimum drying time of 5 hours. The findings could be implemented and utilized for achieving optimum ventilation and drying performances to refine dryer (CDSCD) design.
