  1. 1. Ultrasound Doppler Based In-Line Rheometry - Development, Validation and Application

    Författare :Johan Wiklund; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; Livsmedelsteknik; Technological sciences; non-Newtonian; Chemistry; Kemi; process control; In-line rheometry; Doppler; process monitoring; ultrasound;

    Sammanfattning : The trend within fluid industry is towards continuous production, leading to an increasing demand for new and improved methods that allow real-time monitoring of quality parameters and fast process control. The consistency and viscosity can be described by fluid rheology and are frequently used as quality control parameters. LÄS MER

  3. 2. On the Extraction of Essential Oils by Supercritical Carbon Dioxide and its Influence on the Mesomorphic Phase Structures

    Författare :José da Cruz Francisco; Kemiska institutionen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural oils; fats and waxes technology; Naturliga oljor; fetter; vax; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; phase behavior; soybean lecithin; monoolein; cineole; terpenes; eucalyptus; extraction; Essential oils; supercritical carbon dioxide;

    Sammanfattning : A comparison of essential oils from leaves of Eucalyptus camaldulensis Dehn. obtained by hydrodistillation (HD) and supercritical carbon dioxide (SC-CO2) extraction is presented. Selected major components of the oils showed a predominance of higher molecular weight components in the SC-CO2 extracts than in those obtained by HD. LÄS MER

  4. 3. Some Fluid Dynamic Characteristics in the Scale-up of Rushton Turbine-Agitated Tanks

    Författare :Eva Ståhl Wernersson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; Rushton turbine; turbulent kinetic energy; geometry; local energy dissipation rate; power input; scale-up; anemometry measurements; agitated tanks; turbulence; Kemiteknik och kemisk teknologi;

    Sammanfattning : Turbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. LÄS MER
