    Effect of moisture content on the physical properties of three varieties of sorghum seeds 

    Gikuru, Mwithiga; Sifuna, Mark Masika (Elsevier, 2006-08-31)
    Three sorghum varieties (Kari-mtama, Serena and Seredo) were obtained from the Kenya Agricultural Research Institute and reconditioned to moisture contents ranging from 13.64% to 21.95% db. The reconditioned grain kernels ...

    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 

    Gikuru, Mwithiga; EL-Mesery, Hany S. (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 ...

    Analysis of Fish Fillet Drying Rates under Three Solar Energy Drying Systems 

    Gikuru, Mwithiga; Mwangi, Samuel Gathuki (2009-02-20)
    A small Box type solar dryer with controllable air inlet was designed and tested. The dryer had a mild steel absorber plate and a polyvinyl chloride (pvc) transparent cover and could be adjusted to allow variation in airflow ...

    The drying of onion slices in two types of hot-air convective dryers 

    Gikuru, Mwithiga; El-Mesery, Hany S. (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 

    Gikuru, Mwithiga; El-Mesery, Hany S. (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 ...

    A study of yield characteristics during mechanical oil extraction of preheated and ground soybeans 

    Gikuru, Mwithiga; Lamech, Moriasi (2007)
    Abstract: 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 ...

    Coffee Drying in a Rotary Conduction-Type Heating Unit 

    Gikuru, Mwithiga; Jindal, V.K. (Blackwell Publishing Ltd, 2004-06-01)
    Parchment coffee (Arabica) was dried from an initial moisture content of about 90% to 10% dry basis (db) in a recirculating rotary conduction type heating unit at controlled plenum temperatures of 100, 120 and 140C or ...

    Evaluation of the effect of ripening on the sensory quality and properties of tamarillo (Cyphomandra betaceae) fruits 

    Gikuru, Mwithiga; Mukolwe, Michael Inzoberi; Shitanda, Douglas; Karanja, Paul Nyota (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. ...
