“…D eff increased as the drying temperature increased (Figure 4) and drying at 85 °C yielded the highest D eff by far. The D eff generally ranges from10 −8 to 10 −12 m 2 /s for biological samples (Silva et al, 2022;Aghbashlo et al, 2008). D eff values for lily scales were similar to those of other vegetables and fruits predicted in other studies: 1.02-2.65 × 10 −9 m 2 /s for drying tomato slices from 60-100 °C (Purkayastha et al, 2013), 2.74-4.64 × 10 −9 m 2 /s for drying carrot pomace from 60-75 °C (Kumar et al, 2012), and 1.09-5.99 × 10 −9 m 2 /s for drying thyme from 40-60 °C (Doymaz, 2011b).…”

“…As a necessary element, simple representations are required to predict drying characteristics and optimize drying parameters. Previous studies have evaluated the precise characteristics and established mathematical models describing drying behavior of various vegetables [e.g., garlic (Demiray & Tulek, 2014), carrot (Doymaz, 2017), araticum epicarp (Ataides et al, 2022), banana (Silva et al, 2022), red ginseng (Ning et al, 2021)]. There is limited empirical information on these aspects of hot-air dried lily scales, however.…”

This study investigated the effects of temperature on the drying behavior and kinetic features of lily scales. A series of experiments were carried out at 65, 75, and 85 °C to dry the scales in a laboratory air-ventilated oven dryer. Drying temperature was found to significantly affect drying times and drying rates. The rate curves suggested that the drying process of lily scales occurred entirely within the descending rate period. During the simulation of drying kinetics, Page and Logarithmic models were proven highly accurate by evaluating the efficacy of seven different thin layer models. Based on Fick's second law, the effective moisture diffusivity was determined as 4.12 × 10 −9 , 7.71 × 10 −9 , and 9.49 × 10 −9 m 2 /s for temperatures of 65, 75, and 85 °C, respectively. The calculated figure of activation energy was 42.42 kJ/mol.

“…The air was guided to pass through the banana slices spread in each tray. The heat circulation supported by the forced convection can be used to improve drying efficiency (Silva et al, 2021). The drying temperature and humidity affected by the circulation are parameters in a drying acceleration besides the thermophysical properties of product (Majdi & Esfahani, 2018).…”

An evaluation was carried out on a simple tray dryer of banana slices in the "sale pisang" production. The dryer is designed to use gas fuel and a wood-burning stove as a source of energy. The dryer's performance is analyzed to evaluate its ability to dry the product efficiently and effectively to prevent excessive heat use. The research aims to analyze the temperature distribution in the drying chamber, the profile of the product's moisture content, the drying rate on each shelf, as well as the efficiency of dryers using gas fuel and wood-burning stoves. At an air speed of 0.0176 m3/s, the drying chamber reaches a maximum temperature of 76.2 ℃ using gas and 66.23 ℃ using a wood stove. The use of Liquid Petroleum Gas (LPG) gives an average room temperature of 73.46 ℃, while the furnace gives a less stable pattern with an average temperature of 63.02 ℃. Drying using LPG occurs more quickly with a constant drying rate and a falling rate period of 0.8262%/hour and 0.01504%/hour, higher than using wood fuel which is 0.5482%/hour and 0.0098 %/hour. Within 400 minutes, the product’s moisture content reached 24.64% using LPG and 36.762 using the furnace. The efficiency for heating the drying air is 28.51% and the drying process efficiency is 27% using 8.6 kilograms of LPG as fuel. Meanwhile, using a furnace energy source, the dryer provides a heating efficiency of 15.9% and a drying efficiency of 7.37% with a fuel consumption of 34.12 kg of wood.
