Follow up:

Detailed description of topics:

  • Introduction and course domain.

  • Cooling and freezing of products (temperature profiles, heat extraction, cooling and freezing processing lines, moisture transport).

  • Refrigeration equipment (cooling and freezing tunnels, flat plate freezers, systems for particular products, design methods).

  • Thawing of products (with liquid, gas or steam, radiation, electrical methods or micro waves).

  • Cold storage (building constructions, insulation, doors, transport systems, air circulations and ventilation, controlled atmosphere, refrigeration capacity, humidity, safety aspects).

  • Insulation (demand and properties, humidity and moisture inside walls, constructions for insulation of walls and equipment).

  • Climate control in cold stores (control of temperature and humidity, gas composition, pressure).

  • Liquefied natural gas (processes for liquefaction, storage and applications of LNG).

  • Safety aspects (related to humans, products and the environment).
