Mission Statement
  • In bioeconomical understanding biological materials are needed to provide people with food, energy and materials. Physical properties are a key in automized processing of food-, agri-, pharma- and health care products. The module will:
  • 1. Provide students with fundamental knowledge of physical and rheological properties needed for the engineering design of processing, storage and handling systems for food and biological materials.
  • 2. Provide students with an opportunity to master communicative and technical writing skills by submitting technical reports complete with summary, objectives, methodology, and presentation of results, following rules of convention for data presentation.
  • 3. Provide students with team building and teamwork experiences through self-directed team formation and organization, with grades based on team output and teammate evaluation.
  • 4. Train students in the use of modern computational and experimental testing equipment.

Physical and rheological properties that is needed for the engineering design of systems used in the processing, storage and handling of biolog-ical materials, e.g. rheological, interfacial, thermal, electromagnetic and optical properties of biological materials based on carbohydrates, fats, proteins and properties of complex biological materials like emulsions, suspensions, foams, frozen systems and nano materials as well as communicative and technical writing skills. Lessons are on:Water Activity, Water SorptionPhysical Characteristics (Shape and Size) Volume, Density, Porosity, Permeability and Surface Area Specific Surface Area, Particle Size Distribution Modulus of Elasticity (Bulk, Shear, Young's) Analysis of Force/Deformation Data Creep (Strain Retardation) and Stress Relaxation Rheology of Liquids (Flow Behavior) Mechanical Impact and Aerodynamic Properties Particle Mechanics of Granular Materials Flow and storage of Granular Materials
