PārZ2004, Food Engineering and Equipment I

Course abstract

– The second part of the course describes the design, specific characteristics, and application possibilities of certain technological equipment corresponding to the basic groups described in the first part of the course. The suitability of the described equipment for various foods production and raw material processing tasks is studied in the course.

Learning outcomes and their assessment

After completing the course student will have:
• theoretical knowledge on food processing equipment design, variety and principles of operation – lectures, exam;
• skills to select appropriate food processing equipment for the certain technological goal, develop the scheme of machinery and the graph of equipment use for production of selected product - laboratory works and defence;

• competence - to justify selection of food processing equipment, to explain safety and exploitation - laboratory works and defence.

Course Content(Calendar)

For each topic 1 hour of lectures and 3 hours of laboratory work is planned.
1. Introduction: Classification of food processing equipment, general principles of design.
