Versatile Direct Steam Injection

Pro-active thinking & actions

As an experienced dairy technologist and processed cheese factory manager, it became apparent to Robert ‘Bob’ Smith that cooking systems available to food manufacturers were inadequate for a variety of design, mechanical and operational reasons.

From idea to market

In response to this, Bob built the first RotaTherm® continuous cooker in his family garage in Melbourne, Australia. It was successfully trialed and installed at Murray Goulburn Co-operative’s Cobram plant in 1988. The performance and peer acceptance was so positive that Bob decided to establish Gold Peg International Pty Ltd and begin commercial production of his continuous cooking systems.

Natural expansion from domestic to international

It wasn’t long before Gold Peg was distributing RotaTherm® equipment to food manufacturing plants throughout the world. A great part of Gold Peg’s success has been due to the fact that Bob is a food technologist and factory manager – with very solid operational expertise in food production.


Today the RotaTherm® continuous cooker continues to be the most sophisticated and technologically advanced direct steam injection continuous cooker in the world and is available in a range of models for a wide variety of food applications. It is a credit to Robert Smith’s foresight that Gold Peg is now an international manufacturing force in food production equipment.

Gold Peg are proud to share the exciting news that Bob's contribution to Australia has been acknowledged with him being awarded with an Order of Australia Medal (OAM)...read more.
