“…This shows that the drying chamber temperature was higher than the ambient temperature, with a temperature difference of 13.07 0 C. The temperature fluctuation pattern in the drying chamber followed the solar collector's temperature fluctuation pattern. The temperature test results in the Dafa-type Pliek U solar energy dryer were still above the average maximum temperature of the Aceh region of 34.7 °C [9]. The increase in temperature in the drying chamber is also caused by the presence of a solar collector with a transparent cover as an absorber of sunlight so that heat is trapped in the drying chamber [7].…”

One of the food diversification strategies of coconut commodity is to process it into Pliek U. Pliek U is a typical food of the Province of Aceh, Indonesia, which in its processing stage requires a drying process. So far, Pliek U drying process is often conducted conventionally through direct drying (sun drying), so that Pliek U produced is susceptible to dust and other dirt contamination. This research aimed to design a Pliek U dryer using Dafa type solar energy. The Dafa type solar energy dryer used a turbine ventilator with a vertical axis wind turbine equipped with two solar collectors. This turbine had a simple shape and construction and was arranged like the letter S. While the two parts of the solar collector were used to collect energy from the sun directly. In the experiment, the blank test was carried out in the time range, namely from 10.20 am to 04.50 pm in sunny weather, with an interval of 30 minutes for each temperature data recording. The empty test results of the Dafa type solar energy dryer showed that the average shelf temperature was 44.21 °C, the collector temperature was 45.64 °C, and the ambient temperature was 31.14 °C. This initial test revealed that the performance ability of the tool was very effective in maintaining temperature during the drying process, so that further tests using materials for drying Pliek U may be carried out.

The development of modified greenhouse dryer is the latest drying technology today. The development of dryers with digitalization technology is a necessity in order to increase production efficiency at the farmer/craftsman level. The process of monitoring in the drying room was developed by utilizing data acquisition system technology. Whereas data on temperature, humidity, solar radiation, moisture content were plotted during the drying process. The objective of this study was to monitor the performance of the modified greenhouse dryer of stem stalk water hyacinth (Eichhornia crassipes) based on the Arduino nano microcontroller. The method was divided into three parts: hardware design, programming algorithm development, and dryer performance monitoring. The output of this study is expected to be an alternative method for monitoring of the greenhouse dryer on industrial scale. The results of this study could be an alternative dryer for other agricultural products, the method for monitoring of the dryer in real time will be an important information guiding the farmer during the drying process.

“…al. [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.…”

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.
