Experimental investigation and energy analysis of a solar-assisted fluidized-bed dryer including solar water heater and solar-powered infrared lamp for paddy grains drying

Conventional and intermittent drying modeling of agricultural products: A review

“…Drying condition Heat saving (%) Reference Barley T = 20-25 C 2 9 -44 (Carvalho et al, 2021) Camellia oleifera seeds T = 40-80 C 29.3 (Huang et al, 2020) Corn grains T = 23-36 C 6.1 (Silva et al, 2020) Corn seeds t = 0-20 h 70 (Xie et al, 2020) Green soybeans Seeds t = 0-550 min 53 (Zhao et al, 2017) Paddy grains T = 35-55 C 59 (Mehran et al, 2019) Red beetroot T = 25-85 C 5 0 -75 (Szadzinska et al, 2020) Rough rice grains T = 40 and 70 C 6 8 -72 (Franco et al, 2020) Soybean seeds T = 50 and 70 C 4 2 -46 (Bissaro et al, 2020)…”

Dynamically structured fluidization: Oscillating the gas flow and other opportunities to intensify gas-solid fluidized bed operation

“…When possible, fluid viscosity and density could be modified to alter the flow regime by adequate selection of the gas [26], temperature and pressure [27,28], and even working under supercritical conditions, common in the pharmaceutical [29,30] and energy sectors [31,32]. There are also many ways to supply an additional source of energy in so-called "assisted fluidization" technologies, for example with direct solar irradiation [33,34], using microwaves in fast biomass pyrolysis [35], or introducing radio frequency [36,37] and ultrasound [38,39] in the design of fluidized bed dryers.…”

A detailed investigation of the temperature-controlled fluidized bed solar dryer: A numerical, experimental, and modeling study

“…Average specific energy consumption value was found to be 4.76 kWh/kg water. In a study performed by Mehran et al [24], solarassisted FBD with solar collector and solar-driven infrared heater was analyzed. They compared the system with conventional drying method.…”
