Supplier News

AUSTRALIAN-owned Crest Chocolates has been delivering chocolates and confectionery for the fundraising, tourism, hotel and corporate world since 1956. Their pure milk chocolates are created at their custom-built chocolate factory at Stafford on Brisbane’s northside.

Like many companies today, Crest Chocolates must adhere to the strict safety policies and guidelines outlined in the Workplace Health and Safety Act 1995 and Australian Standard - AS 4024. 1-1996: Safeguarding of machinery - general principles. With safety in mind, manufacturing equipment at the factory has been upgraded in recent years.

Alan Davis from Crest Chocolates identified that the 1000 litre and 200 litre capacity chocolate vats, which are used in the manufacturing process, required safety upgrades. Used for mixing and stirring chocolate, the vats have high torque internal agitators that rotate at a low speed.

Due to the high power associated with these agitators, it was deemed necessary to introduce a safety system that would prevent the lids of the vats from being opened during operation.

A safety specialist from MPA Engineering , located at Brendale in Brisbane was contracted to install two types of Sick safety switches to the chocolate vats.

When the lids are now closed the sensors become activated, and if they are opened during the manufacturing process, the agitators stop immediately.
