“…Specifically, Replication 1 was the only one that had a duration of 3 days in contrast with the other replications, which their duration was 2 days. This drying duration (2-3 d) is comparable to other alternative drying methods, such as solar drying, where the drying duration varies between 1 and 3 days depending on the type of solar drier [35].…”

Agricultural product drying is of great importance as it is a reliable method for fruit and vegetable preservation. Tackling the high energy consumption of the process will reduce the final product cost and mitigate greenhouse gas emissions. In this work, a passive drying method was experimentally evaluated. The method was based on the principle of the stack effect taking place in the solar chimney structure. Different types of solar chimneys in terms of dimensions and materials were evaluated for the drying of banana and potato slices. The results of the experiments showed that the drying rate was close to solar drying systems. Parameters such as height and material characteristics of drying tubes, as also weather conditions, influenced the drying rate. It was found that the banana and potato slices were dried at a satisfactory rate for almost 48 h during the summer period in Greece. From the parameters of the drying tubes that were varied, it was found that both the height and material played a major role, as did the air flow rate. With the increase in the drying tube by 1 m and with the choice of proper manufacturing material, an increase in the flow rate between 40% and 100% can be achieved. When only the color of two 3 m-high tubes changed, the flow rate varied between 4% and 15%. The proposed method has almost zero energy consumption, and it could be used as a standalone or as a part of a hybrid drying system. It can also be adjusted in existing greenhouse-type agricultural structures as a parallel operation system.

“…From the results, with respect to the temperature, inside the solar dryer it doubles the temperature outside the solar dryer, this occurs due to the brass and its color, which is an accumulating element of heat energy. The relative humidity outside the solar dryer was 46.08%, for the proper drying of the precooked potato cut into sticks it decreased to 33%, this humidity percentage allowed to reduce the drying time of the precooked potato mass to 8 hours, compared to traditional drying time which is more than 24 hours [Norton, 2017].…”

“…To solve these issues, solar dryers are used because they are a closed drying system that produces heat inside the drying chambers to dry the intended products without letting them be contaminated by external factors [27]. This process leads to faster moisture removal from products being dried.…”

Fish is a vital source of proteins and nutrients and can be eaten in many forms, one of which is dried fish. In Cambodia, fish is mostly dried in traditional ways and can be subject to dust, flies, rain, and weather events, resulting in low-quality products. These issues can be addressed by using solar dryers. Thus, this study was aimed to (1) compare the socio-economic conditions between dried fish processors practicing traditional drying and those using solar dryers, (2) to identify potentials and challenges to dried fish production between the two groups, and (3) to determine the factors affecting income. The study was conducted between May and August 2023, using purposive sampling to select two groups of dried fish processors in three provinces along the river systems in Cambodia. The selection criteria included (1) engagement in year-round dried fish production, (2) at least 100 kg of raw fish dried per month, and (2) willingness to participate in the interviews. Then, 35 dried fish processors that practiced traditional drying and 9 processors that utilized solar dryers were selected. T-tests, chi-square tests, analysis of variance (ANOVA), Likert scale analysis, and multiple linear regression model were used to compare the socio-economic conditions, perceptions, and the factors affecting the income. The results show that the solar dryer group used more labor, produced more dried fish, and had a higher selling price when compared to the traditional drying group. They had more opportunities to attend training and trusted the solar dryer technology. Meanwhile, the traditional drying group preferred direct sun-drying, but dried fish quality was better when solar dryers were used. Experience, total costs, and the use of solar dryers affect the income. In conclusion, using solar dryers tends to produce dried fish of better quality and a higher income, which is good for both health and improved livelihoods of fish producers and sellers.
