  • Drying characteristics of orthodox broken type tea 
    Raveendran, K; Amarasinghe, ADUS; Botheju, WS
    Drying characteristic of Orthodox broken type tea was examined using a laboratory-scale fluid bed tea dryer. Drying experiments were carried out at loading of 29 kg/m2 and moisture content of tea was reduced from 106% to ...
  • Effect of loading density on quality of dried teas in fluidized bed drying 
    Raveendran, K; Amarasinghe, ADUS; Botheju, WS
    Loading density is a critical parameter that affects the drying behaviour of teas in a fluidized bed dryer and hence the final product quality. During fermentation process, polyphenols available in teas are converted ...
  • Study on bedplate configuration for fluidizing orthodox broken type tea 
    Raveendran, K; Amarasinghe, ADUS; Botheju, WS; Jayarathna, WAR [Conference-Abstract]
    Orthodox broken type tea produced in Sri Lanka is popular for its distinct characteristics. Fluid bed dryers which are widely used in manufacturing of tea has been changed over the years and consequently, drying the tea ...
  • A Study on fluidization behaviour of orthodox-rotorvane teas 
    Raveendran, K; Amarasinghe, ADUS; Botheju, WS [Conference-Abstract]
    Orthodox-Rotor-vane teas dried in liquidized bed driers in tea factories at present have, on average, smaller size particles than that of teas produced a decade ago. Further particles are distributed over a wide size range. ...
