  1. 1. Fouling modelling in a UHT unit based on plant data.

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Thai Lam; [2023]
    Nyckelord :UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

    Sammanfattning : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. LÄS MER

  3. 2. Kartläggning av processvariationer och optimering av värmebehandling i produktionen av gurkmix

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Johan Hallbeck; [2021]
    Nyckelord :Gurka; Värmebehandling; Livsmedelsteknik; Teknisk mikrobiologi; Cucumber; Thermal treatment; Food engineering; Applied microbiology; Technology and Engineering;

    Sammanfattning : Cucumber relish is a classical Swedish product that is produced in large scale in an Automatic process. The goal of this project was to map the process variations and optimize the heating process. The heating process consists of one tubular heat exchanger where the cucumber relish is heated and one holding cell where it is kept warm. LÄS MER

  4. 3. Fouling Dependency of Air in Dairy Processing

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erik Lorin; [2018]
    Nyckelord :Fouling; Dairy; UHT; Bubble; Bubble induced fouling; Drying; THE; Dairy Processing; Processing; Bubble Nucleation; Differential Pressure; Oxygen sensors; chemical engineering; kemiteknik; Agriculture and Food Sciences; Chemistry; Technology and Engineering;

    Sammanfattning : In this master thesis project, the formation of fouling on heat exchanger surfaces in dairy processing and mainly the influence of air was examined. Based on prior experimental findings regarding the influence of air bubbles in combination with calculations based on solubility properties of air in milk, a hypothesis was stated. LÄS MER

  5. 4. Convective Heat Transfer with Nanofluids

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Simon Ströder; [2011]
    Nyckelord :;

    Sammanfattning : The present Master thesis is concerned with forced convection heat transfer in laminar and turbulent flowwith nanofluids. Nanofluids are defined as a colloidal suspension of particles in a base fluid, where theparticles have a characteristic length of less than 100 nm. LÄS MER
