Cleans up the coffee dust

Green coffee beans come into the plant via bulk containers and are tipped into floor grills before being cleaned. Green bean dust is a known potential allergen and reducing/eliminating it is important for staff. Operators previously used brushes or compressed airlines to collect the dust.

During a DSEAR assessment, blowing the dust was identified as a problem as the fine dust has potential explosive qualities. The area is now classified as ATEX Zone 22 and any clean-up must be carried out with ATEX Zone 22 certified equipment.

Additionally, incoming containers must be thoroughly cleaned before they are returned to the docks for use by other customers and products.

Mondelez approached Nilfisk’s Industrial Vacuum Solutions area manager, Paul Gage who, after a full site survey, specified a 415V CTS40 Z22 industrial vacuum with 15m of anti-static hose and tools. The 4kW vacuum is fixed to the wall from where the hose can clean down the entire production area and the haulage containers.

The compact CTS40 is easy to use and suitable for confined areas where a powerful machine is required. The steel waste bin has a capacity of 50L, the wheeled design and quick release mechanism makes for easy disposal of hazardous products. 

Larry Parkes, warehouse shift lead for Mondelez in Banbury commented on the solution now in place: "We previously used compressed air lines to blow the dust out prior to collection but this was not ideal. The Nilfisk CTS40 is a much improved solution, the advice and support we have received from Nilfisk both pre and post-sale was excellent, they really know their stuff."
