CME8130 : Food Processing

  • Offered for Year: 2023/24
  • Module Leader(s): Dr Colin Hare
  • Owning School: Engineering
  • Teaching Location: Newcastle City Campus
Semester 1 Credit Value: 10
ECTS Credits: 5.0


To outline the challenges involved with food processing, including:
- Handling complex fluids such as suspensions and emulsions
- Characterising particles and handling powders
- Preventing contamination and maintaining a sanitary process

Outline Of Syllabus

The module will first focus on rheology and processing implications of dispersions. Classification of dispersions (e.g. suspensions, foams and emulsions) will be explained, followed by a detailed examination of the interaction forces that control the flow behaviour (rheology) of these complex fluids. The focus here will be on suspensions and emulsions with relevant food examples discussed.

Particle properties such as size and strength will be explained, including how these can be characterized and how to account for the distribution in a powder. Problems of powder handling such as segregation and poor flowability will be outlined, including how to design a hopper to ensure reliable flow, taking account of the stresses in the powder bed.

The causes of contamination, cleaning practices and guidelines for hygienic equipment design will be discussed. Specific unit operations often encountered in foods industries, such as spray drying, fluid mixing and homogenisation will also be explained, accompanied by design equations.

Consideration will be given to how a food manufacturer can manipulate the formulation of the product to achieve desirable properties for the consumer.
