Tetra Pak Hygienic Powder Bin Aerators

Tetra Pak’s Hygienic Powder Bin Aerators can be installed on powder bins, silos and batch hoppers to promote powder flow during discharge and prevent powder compaction during long-term storage. The working principle is based on introducing food-grade compressed air between the bin wall and the powder. Fluidising with compressed air loosens powder inside the bin and reduces the friction angle between the product and bin surface.

The aerators eliminate the risk of valve rubber parts falling inside the hopper. The flush poppet-style valve head avoids the retention of powder particles between the valve parts and the inside of the hopper walls, preventing product cross-contamination and microbial growth inside the powder storage plant.

The Retrofit Hygienic Powder Bin Aerator M25 is supplied fully assembled and allows easy installation in new and existing plants, with no additional work to retrofit the bins with previously installed fluidisers of other brands.

The Externally Fitted Hygienic Powder Bin Aerator M50 allows mounting of the aeration points from outside of the bin, making it suitable for aeration of small vessels, vessels with difficult internal access or when handling difficult powders. It enables fast valve replacement and gives easy access to the product inside the hopper during inspections or maintenance.

The Hygienic Powder Bin Aerator M75 for powder handling systems with cleaning in place (CIP) delivers compressed air, CIP fluid or drying air via the hygienic aerator valve inlets. It can be installed on a new plant or retrofitted onto powder vessels as part of an existing CIP system.

Hygienic Powder Bin Aerators are air activated and controlled via pilot solenoid valves. They have a sanitary design, are fabricated from stainless steel or food-grade plastics, and require minimal maintenance.
