“…In the rural communities, sun drying is the most prevalent method of fish drying, and a large amount of the dried fish is spoiled each year due to lack of proper drying techniques, preservation and storage facilities particularly in the rainy seasons (Dey et al, 2016;Payra et al, 2016). As a result, the physical and organoleptic qualities of the most of the traditional sun dried products available in the domestic markets are inferior (Kumar et al, 2017;Nath, Saikia, Saikia, Chowdhury, & Majumder, 2018;Paul, Reza, Islam, & Kamal, 2018).…”

The drying behavior of different freshwater fishes (with/without scales) is investigated using a simple convective heated air dryer. Drying processes are analyzed to study the kinetics of drying, shrinkage dependent variable effective diffusivity, convective heat and mass transport, and the energy aspect of drying. Among the drying kinetic models, Hasibuan–Daud and Haghi–Angiz‐I models produce the best fit for fishes with scales and Hii model produces the best fit for fish without scales. Diffusion analysis performed based on simplified solution of Fick's diffusion equation shows higher effective diffusivity for fish without scales, proving additional barrier from scales (for fish with scales) that need to be considered during dryer design. Calculated instantaneous heat and mass transfer coefficients (different for fish with or without scales) also agree with this observation, accentuating the difference based on scales. Drying process for all fishes obeys the heat‐mass transfer correlation. Estimated parameters such as effective diffusivity (0.2–1 × 10−9 m2/s) and convective heat and mass transfer coefficients (7–14 W/m2/K and 2.8–4.5 × 10−6 m/s, respectively) can be utilized in designing different fish drying systems. Average and instantaneous total energy consumption, specific moisture extraction ratio, and specific energy consumption are evaluated in order to provide a comprehensive picture of the drying process.Practical ApplicationsFresh‐ and salt‐water fishes account for major sources of protein‐rich food for substantial parts of the population in underdeveloped and developing nations. To circumvent the wastage associated with microbial contaminations during prolific seasons, fish drying has been widely employed as a way of preserving this perishable food. Convective drying of agricultural products as well as marine foods is a commonly employed drying method for food preservation. This study investigates the drying behavior of three different freshwater fishes using an in‐house constructed forced convective air dryer. The experimental drying characteristics and estimated parameters by model fitting during fish drying will be particularly applicable in the wide field of fish drying. The outcome of this study can also be utilized for more effectively designing and evaluating low‐cost convective fish dryers.

“…Indonesian fishermen perform a traditional process of drying fish using direct sunlight. Drying using this method is usually done by placing fish products on fishing nets, mats, floor mats, or woven bamboo and placing them in the sun [20]- [23]. This method is unsanitary and supports products that have lost weight due to insect, bird, cat and other animal losses.…”

The abundance of fish catches in Indonesia is excellent potential. Still, if the abundant results cannot be adequately managed and are just wasted, it will eventually lead to bad things. This problem was also found in Seraya village, Karangasem, Bali, where large fish yields and the fish processing process were still constrained by weather and environmental conditions causing the expected results to not be achieved. To overcome this, a photovoltaic (PV) system-based fish dryer was developed that can assist the fish drying process. Utilization of this system is also supported by good solar energy potential. The system can generate 402.78 Wh of electrical energy per day, covering 104.89% of the electrical energy demand of the fish dryer. The results of statistical tests using the Mann-Whitney test for fish weight and unpaired t-test for fish moisture content showed no significant results (p0.05). This value states that there is no difference in the results of drying fish with the PV system and the traditional method. From this, we can conclude that fish drying using a solar power system works similarly to conventional fish drying methods.

“…In addition, the product will be easily exposed to dust. The drying process will be delayed if it rains, so the expected results are not optimal and the amount of production produced is not appropriate [18]− [21]. These conditions led to an idea to design and manufacture a hybrid fish dryer by utilizing energy from the sun with the type of greenhouse effect.…”

<span>The catch of fish is so large and often not completely sold, causing the fish to be wasted for free. This situation even indirectly causes environmental pollution around the area where fishermen live. To overcome this problem, a fish drying machine was made using a PV system. This tool is also a form of solving the problem of the traditional fish drying process which is sometimes not clean, safe, and depends on direct sunlight. This PV system can meet 169.95% of the need for 240 Wh/day of electrical energy from fish dryers. PV system can produce electrical energy for 407.81 Wh/day, where the largest energy can reach 520 Wh and the smallest is 160.8 Wh. The results of the analysis of the impact of using fish dryers socially and economically also gave significant results (p<0.005), where there was an increase from before and after the use of fish dryers experienced by fishermen. When viewed from the perspective of fishermen on the tool, the accuracy of the use of the tool, the benefit factor, and the shape of the fish dryer, the fishermen gave a good response, with an average value of <br /> 4.19-5.26.</span>
