Cleaning multi-deck ovens between batches.

In an industrial bakery, multi-deck ovens have to be cleaned between batches to keep the product consistent and the process hygienic. But the ovens are hot and awkward to reach across several decks, and cleaning them by hand between bakes was a lengthy, complex job.

Every minute spent cleaning is a minute the oven is not baking — so the bakery needed a way to clean thoroughly, at temperature, without holding up production.

Depureco supplied a PUMA 15 P built for the environment: an 11 kW side-channel blower specifically treated for high-temperature work, paired with a NOMEX filter rated to 250°C so the system can pull hot debris straight from the ovens without waiting for them to cool.

Six brush-tipped suction arms on a support structure move back and forth to reach into each deck for a meticulous clean, with a rotary level sensor and remote control managing the cycle. Debris collects in a 175-litre bin and empties through a tiltable bin kit — so operators clean the ovens quickly and safely, batch after batch.

Quicker, more thorough cleaning between bakes keeps the ovens hygienic and the line moving — improving the quality of the finished product, supporting hygiene compliance and saving time on a job that used to hold up production.
