  1. 26. Processing of raw Cassava (Manihot esculenta) - Experiments and Modelling

    Författare :Carola Rojas; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amylopectin; hydrodynamic radius; field flow fractionation; overlap concentration; minerals; enzymes; cassava; hydrolyses; glucose; maltose; sucros; amylase; hydrolyses kinetics; starch granule structure; radius of gyration; drying kinetics; heat transfer; high pressure homogenisation; mass transfer;

    Sammanfattning : The objective of the present thesis was to understand how the quality and performance of dried cassava products could be developed by drying and other processing steps. This goal was achieved in several stages. LÄS MER

  3. 27. Syngas production by integrating thermal conversion processes in an existing biorefinery

    Författare :Katarina Åberg; Anders Nordin; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; biofuels; syngas; gasification; torrefaction; methane reforming; H2 CO ratio; system analysis; CO2 negativity;

    Sammanfattning : The use of carbon from fossil-based resources result in changes in the earth’s climate due to emissions of greenhouse gases. Biomass is the only renewable source of carbon that may be converted to transportation fuels and chemicals, markets now fully dominated by traditional oil supply. LÄS MER

  4. 28. Functionality of Spray-Dried Whey Protein Powders - Surface Composition, Particle Morphology and Rehydration

    Författare :Ida-Marie Andersson; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Milk serum protein; Lactose; Whey protein powders; Spray drying; Particle morphology; Surface composition; Rehydration; Functionality; Milk serum protein; Lactose; Whey protein powders; Spray drying; Particle morphology; Surface composition; Rehydration; Functionality;

    Sammanfattning : Whey protein powder functionality is expected to be closely linked to both structure and properties of the proteins. It is essential that whey protein powders are easily dispersed and dissolved in order to fulfil the specified nutrient content and the functionality in the final product. LÄS MER

  5. 29. Heat and Mass Transfer Effects in a U-Bend in Pneumatic Drying

    Författare :Muslikhin Hidayat; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Pneumatic conveying drying is a widely used process in many engineering applications. Due to the high velocity of the drying medium and the limited conveying distance, the drying times of theses dryers are typically short, in the order of seconds. LÄS MER

  7. 30. Energy and Resource Efficiency in Convective Drying Systems in the Process Industry

    Författare :Jan-Olof Andersson; Zhifa Sun; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Growing concern about environmental problems has increased the public’s interest in energy usage. The subsidies for biomass, together with the rising energy prices have madebiomass a desirable product on the energy market. LÄS MER
