The interactions between refrigerated foods and their surroundings, and these surroundings and the refrigeration system, are often as important as the technical aspects of the refrigeration system itself.  Food will often have characteristics that require a certain type of refrigeration process that preserves the quality of the product.

RD&T has a great deal of expertise in the interaction between foods and refrigeration systems and so can provide a complete package to help design, troubleshoot and optimise food refrigeration systems.

RD&T have been involved in projects that include:

• heat removal and temperature reducing operations of primary and secondary chilling, freezing and crust freezing
• temperature maintenance operations of chilled and frozen storage, transport, retail display and consumer handling
• thawing and tempering under refrigerated conditions
• optimisation of domestic and commercial refrigerators and freezers
• design, optimisation and testing of commercial refrigerated cabinets
• reducing energy consumption
• troubleshooting refrigeration system problems throughout the cold chain

Often tools are used to help optimise refrigeration systems and refrigeration of food . These tools include computer modelling such as:

• computational fluid dynamics (CFD) for predicting temperatures, airflows, and energy requirements in rooms and refrigerated cabinets
• heat and mass transfer models of foods and cold storage spaces
• refrigeration system models

Our experience, and the combination of modelling and measurement that are used in most of our projects enable us to save our customers considerable time and money.
