Precision biscuit making

A bit of precision biscuit making has increased the output at McVities biscuit factory in Manchester. Using ABB Industrial Systems’ ACS 600 AC variable speed drives, the moulder, extraction web and conveyor speeds can be more accurately controlled than they were before so biscuits can be placed closer together. This allows n extra lane of biscuits placed on the extraction web conveyor, giving improved productivity. If speed is not accurately controlled biscuits can overlap and join together when baked.
