Solar dryers have always been criticized for their lower performances. There are numerous ways to define the performance of a solar drying system such as thermal performance, drying kinetics, environmental aspects, economic evaluations, and quality of the dried product. Different modeling techniques have also been developed to design and analyze solar dryers and drying processes. This article presents a systematic, comprehensive, and state-of-the-art overview of various performance indicators and modeling techniques used for the evaluation and analysis of solar dryers, especially domestic and low cost solar dryers. Environmental analysis has severe global implications, and product quality is one of the biggest concerns of consumers. But the environmental impact and product quality assessments for domestic solar dryers are observed to be rarely reported in the literature. The use of modeling techniques in solar drying has changed the way of analyzing any thermal system. Here, an attempt is made to establish an overall assessment criterion for domestic solar dryers and to give a one-stop solution for researchers and users around the world.

“…Desiccating is a preservation procedure to reduce mycotoxin contents. A low-cost and simple inflated solar dryer has been designed for smallholder chili farmers [20]. In a single layer 5-15 cm deep, the performance of 3.5-ton red chili was evaluated using the inflated solar dryers (Figure 6).…”

“…One of the alternative dryers with energy efficiency, a cost-benefit ratio, and affability to the environment is an inflated solar dryer [15]. The dryer has been widely used to desiccate a variety of products of grain, corn, oyster mushrooms, and chili [15][16][17][18][19][20]. Inflated solar-energy-utilized dryers are used to dry agricultural products with their unique features such as being simple in design, easily transportable, and low maintenance compared to mechanical dryers.…”

“…They can be installed in new locations in a very short time and prevent excessive heat from the top-layer objects exposed to sun rays [6]. The inflated solar-energy-utilized dryer provides an opportunity to increase the quality of the product because it inactivates mycotoxigenic fungi, enteric bacteria, and browning enzymes [20]. This study aimed to review in depth the features and advantages of an inflated solar dryer.…”

Drying is a mass transfer process consisting of the removal of water or another solvent by evaporation from a solid, semi-solid or liquid. This processing technique can be used to preserve agricultural products. Insufficient drying techniques may result in a progressively worse standard of the product. A number of different sources of energy are commonly utilized in drying processes such as fuel or biomass. The shortage of fossil fuels and expensive processes may damage the environment; consequently, solar-energy-utilized dryers become the main choice for drying agricultural crops. The inflated solar-energy-utilized dryers were used to dry agricultural crops because the design was simple and easy to operate and maintain, and the dryers prevented excessive heat on the top layer of the exposed object to the sun’s rays. In addition, they could be installed in new locations in a very short time. This study aimed to review in depth the inflated solar-energy-utilized dryers and found out their advantages. What’s more, it paid particular attention to providing a comprehensive description of the design of inflated solar-energy-utilized dryers and their application to a variety of different agricultural commodities. The results of the study showed that the inflated solar-energy-utilized dryers were both faster for drying and improved the product quality regarding the aflatoxin level and impurities.

“…In addition, there is a risk that cereal grains and other products may be contaminated with aflatoxin. In this regard, numerous studies have been undertaken on the natural convection of solar drying for agricultural products [13][14][15]. For successful pest management particularly for store grain pests, use of solar energy with specified materials, tools and techniques achieved a certain lethal dose of heat without affecting the seed quality [16] but still require further improvement for maximum seed volume and efficiency.…”

Worldwide, stored grain pests are massively infesting most stored crops and their by-products. The main losses are due to infestation of these pests occurring on various carriers just prior to harvest, during storage or shipping. Methyl bromide and phosphine fumigation have been widely used for phytosanitary treatment of stored grains but are recognized as highly effective in depleting ozone, and similarly, residue-free grains are important for thermal disinfection. Solarization is one of the best ways to manage and disinfect crops, the traditional solarization methods are already practised by farmers but are inefficient to kill all stages of pests and require additional land exposed to the sun. In this work, thermal disinfection systems using solar heaters are proposed, designed, and developed to offset the actual lethal heat window. For the experiment work, the solar heater boxes were constructed in an octagon shape with 135o at the base for trapping maximum heat inside the solar the heater box. The characteristics of the proposed system proved simpler, faster, and inexpensive but equally effective to achieve the desired results in terms of heat generation and seed moisture.
