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 ...
Evaluation of the effect of ripening on the sensory quality and properties of tamarillo (Cyphomandra betaceae) fruits
(Elsevier, 2007-03-31)
Tamarillo (Cyphomandra betaceae) fruits were sourced from a single farmer from the Central province of Kenya soon after harvesting. The fruits were then cleaned and sorted in order to remove all immature and damaged fruits. ...
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 ...
A study of yield characteristics during mechanical oil extraction of preheated and ground soybeans
(2007)
Soybeans were extracted for oil by compressing a ground sample at various operating pressures, pressing durations and product bulk temperatures. The oil yield from the various operations was measured and expressed as a ...
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 ...
The drying kinetics of kale (Brassica oleracea) in a convective hot air dryer
(Elsevier, 2005-12-31)
The effect of air temperature and sample thickness on the drying kinetics of kale was investigated using a convective air dryer at a fixed airflow rate of 1 m/s and drying air temperatures of 30, 40, 50 and 60 °C. The ...
Research trends in modeling, optimization and control of the drying operation
(2007)
Drying food is an extremely sensitive operation that requires the proper monitoring and control of the heating medium temperature as well as the length of time that the product is exposed to this temperature. Since the ...
Physical changes during coffee roasting in Rotary Conduction‐Type Heating Units
(Blackwell Publishing Ltd, 2003-08-23)
Coffee beans were roasted in a rotary conduction-type-heating unit under constant heating surface or product temperatures ranging from 200 to 240C or 170 to 210C, respectively. the roasting duration was varied from 0 to ...
