Suction and filtration system for food dust

To ensure maximum efficiency in food dust filtration, GGE has designed and manufactured two customised filter units for a leading company based in Perugia (Italy) that builds robotic cells for the food industry.

The two filter units were specially designed by our technical department based on the end customer’s requirements: as they were to be installed in a food production department, these two filter units were built to operate at high negative pressure and guarantee a high degree of filtration, in full compliance with the food industry’s health and hygiene regulations.

TM EVO filter unit for food dust

In order to extract dust more effectively, we have redesigned our TM EVO cartridge filter unit with a special structure that maintains high filtering capacity even at high vacuum levels.

The dust extraction and filtration system consists of several parts.

• The filtering body has a cylindrical construction with a diameter of 1 m and houses 4 antistatic filtering cartridges inside. The cartridges are cleaned by means of an automatic cycle of compressed air jets in countercurrent, managed by the Eco-Compact APC digital control unit.
• The extracted dust is discharged into a wheeled bin located at the base of the filter unit, which is easy to remove for maintenance operations. The discharge hopper has a level indicator with a warning light, which signals when the collection bin is full of dust and the inner bag needs to be replaced.
• Air suction is provided by an 18.5 kW DT centrifugal fan located on the side of the TM EVO filter unit and connected to it by a dedicated pipe. Since the filter unit is installed inside the production department, the fan is placed in a soundproofing box, which reduces the acoustic impact on the surrounding environment.
• Before being returned to the working environment, the extracted air is further filtered by an H13 absolute filter, with a filtering efficiency of 99.95%.

Management and automation of the extraction system

The filter unit start-up and shutdown are managed by an electrical control panel designed by our team of technicians and installed on board the filter unit.

To optimise the machine’s energy consumption, an automatic inverter is installed in the panel, which can adjust the fan’s operating frequency based on actual suction requirements. This allows to:

• reduce electricity consumption;
• extend the service life of components;
• optimise system performance based on operating conditions.
