Specific Energy Consumption of Onion Slices During Hot-air Convection, Infrared Radiation and Combined Infrared-Convection Drying
(AENSI Journals, 2014)
Total energy requirement and specific energy consumption for drying of onion slices
were evaluated using various drying methods including hot-air convection, infrared
radiation and hot air convection-infrared combination ...
Humidity Control System for Wine Maturation Structures
(2013-12-13)
Abstract. Fogging systems can be used to maintain the high humidity required in wine aging structures at acceptable levels during the day and as long as temperature inside the wine maturation store is rising. However, as ...
5 Infrared Drying
(CRC Press, 2010-07-26)
This chapter will present the mechanism, techniques, and advantages of infrared (IR) drying
for various food and agricultural products. The propagation of IR radiation from a source
(considered as any material at a ...
Mathematical Modelling of Thin Layer Drying Kinetics of Onion Slices Hot-air Convection, Infrared Radiation and Combined Infrared- Convection Drying
(AENSI Publisher, 2014)
Onion slices were dried in convection hot-air, infrared radiation and combined infraredconvection
hot air dryers. A systematic experimental design was applied to analyse
drying kinetics due to the effect of type of dryer, ...
Comparison of a gas fired hot-air dryer with an electrically heated hot-air dryer in terms of drying process, energy consumption and quality of dried onion slices
(Academic Journals, 2012-08-14)
Onion slices were dried in either a gas-fired hot air dryer or an electrically heated hot air dryer at air temperatures of 50, 60 or 70°C, and at air flow velocities of 0.5, 1.0 or 2.0 m/s. Records of the drying rates and ...
Alternative methods of harvesting and storage of grass biomass in a semi-arid region
(Academic Journals, 2012-04-12)
Biomass is considered a potential feedstock for many renewable energy production systems and interest especially in grass production has increased markedly in the last two decades. The present work focuses on grass biomass ...
The potential for second generation bio-ethanol production from agro-industrial waste in South Africa
(Academic Journals, 2013)
There has been a sustained and growing interest in the production of liquid fuel from biomass in recent years. South Africa is a large producer of sugar, maize and wheat among other agricultural products that release big ...
The drying of onion slices in two types of hot-air convective dryers
(Academic Journals, 2012-08-07)
Drying experiments were carried out using two types of convective hot-air dryers such that the hot air passed perpendicularly through a thin layer of onion slices in one dryer while the air passed parallel to the thin layer ...
Performance of a convective, infrared and combined infrared-convective heated conveyor-belt dryer
(Springer, 2015-05)
A conveyor-belt dryer was developed using a combined
infrared and hot air heating system that can be used in
the drying of fruits and vegetables. The drying system having
two chambers was fitted with infrared radiation ...
Mechanical expression of oil from grated and preheated coconut meat Botswana Journal of agricultural sciences
(2015)
Coconut oil was extracted from grated coconut using a hydraulic pressing method after the coconut gratings were preheated at heating medium air temperature in the range of 30-90oC and heating durations ranging from zero ...
