“…A greenhouse solar dryer that uses PCMs stores and releases thermal energy, which helps maintain a stable internal temperature and enhances the efficiency and consistency of the drying process. [57] PCMs have the ability to absorb heat when the temperature within the dryer exceeds a specific threshold, and subsequently releases this stored heat when the temperature falls below that threshold. This procedure facilitates the maintenance of a consistently controlled drying temperature, which is crucial for attaining superior drying outcomes.…”

This review reports recent developments in solar greenhouse drying systems in conjunction with hybrid technological features and their designs, operations, and economic implications as well as application in agro‐food product processing. Solar energy is one of the most efficient renewable energy sources to be used as an alternative to fossil fuels. This form of energy is the finest option for space heating and electricity generation among the available renewable energy sources. Solar energy can be used directly or indirectly for dehydrating agricultural and nonagricultural products. However, the products are susceptible to natural disasters such as rain, insects, and animals in open‐air sun drying. Solar greenhouse drying systems in conjunction with hybrid technological features are one of the most recent applications used in the agro‐food processing sectors. The review shows that the quality of products dried in conservatories is superior to that of products traditionally dried under the sun. Further, higher sustainability of the solar greenhouse‐oriented hybrid drying system in terms of embodied energy, energy return time, CO2 emission, net CO2 mitigation, and carbon credit can also be observed with the strengths, weaknesses, opportunities, and threats analysis, i.e., strengths, weaknesses, opportunities, and threats of solar dryers. This shows the framework for abundant real‐world applications.

“…Many investigations are available in the literature on application of PCM in solar dryers for temperature control, heat storage and continuous operation during off shine periods. [49][50][51][52][53][54][55] The literature shows that various modifications have been tested to improve the performance of solar dryers. The present study has been planned to investigate the effect of an air cavity around the drying chamber in a natural convection domestic solar dryer (NCDSD) under no-load conditions.…”

Solar dryers have been tested with various simple and complex design modifications for better efficiencies. This article attempts to investigate the effect of a very simple design modification on the no‐load performance of a natural convection domestic solar dryer (NCDSD). A direct‐type domestic solar dryer has been developed with an air cavity surrounding the drying chamber. To compare the effect of air cavity, a domestic solar dryer without air cavity has also been developed and both the dryers were tested simultaneously under the climate of Hisar, India. The values of thermal efficiency were calculated along with convective heat transfer coefficient from absorber plate to the drying air. Both the dryers were also analyzed by developing finite element models in COMSOL multiphysics computer software. The no‐load thermal efficiency for the domestic solar dryer without and with air cavity was found to be 22.68% and 34.08%, respectively. The values of coefficient of correlation for modeled and actual drying tray temperatures for dryer without and with air cavity were 0.980466 and 0.9833917, respectively. The proposed finite element model would be helpful in the design and development of NCDSDs.
