Andrew Murray has been running his own consultancy since 1985. Andrew Murray Consulting is active within many of the sectors of the food processing industry both in South Africa and in other countries.

Specialist fields include the processing of fruit, vegetable and dairy products particularly where such unit operations as heat exchange, pasteurisation or evaporation take place. The range of products and operations handled by AMC is, however, wide. Many projects undertaken to date have been for on-farm processors.

Because of strong ties (and proven working relationships) with a number of other consultants and research organisations in related fields such as food science and other areas of engineering, multi-disciplinary projects can and have been undertaken by AMC.

Andrew Murray also undertakes energy audits and hygienic design audits based on SANS 14159  and runs short courses in these fields.
