Centralized system for the vacuuming of flour and food powders

Explosion risk from food dust

Confectionery production involves handling volatile ingredients with specific challenges:

• Accumulation of residues: flour and sugar were constantly settling along the production lines.
• ATEX hazard: confectionery dust is potentially explosive if saturated in the air or accumulated in large quantities.
• Multi-line coverage: need to serve three different production lines simultaneously without loss of power.
• Structural requirement: need for a fixed system that would eliminate the need for mobile extractors between process machines.

Third-party certified centralized system

Delfin implemented a centralized system configured to operate at the highest safety levels:

• MTL3533 EX1/3D Extractor: three-phase floor-mounted version, certified for Zone 20 (indoor) and Zone 22 (outdoor), updated in accordance with the latest safety regulations.
• Cyclone separator: unit dedicated to the reduction and pre-separation of material, essential for protecting the main filtration system.
• Integrated automation: 24V electrical panel with the option of local or remote control for total system management.
• Fixed infrastructure: connection to a network of fixed piping designed to optimize flow rate at every suction point.

Certified safety and production efficiency

• Risk mitigation: safe handling of combustible flours and sugars in full compliance with ATEX regulations.
• Filtration efficiency: the cyclone intercepts most of the material before the filter, reducing routine maintenance.
• Healthy working environment: drastic reduction in airborne dust, ensuring more effective cleaning of production lines.
• Scalability: a user-friendly centralized system already designed for future expansion or integration of new lines.
