AZO's hygienic design feeding hopper serves to feed bulk solids in powdered and granular form into closed materials handling systems, especially in areas calling for the highest standards in hygiene. Products can be fed from sacks, boxes, barrels or similar receptacles.
The feeding hopper is available in two different grades of stainless steel and, depending on the surface finish, has surface roughness of < 0.6 µm or < 0.8 µm. The radii on the inside of the feeding hopper are greater than 50 mm and can be cleaned leaving no residue at all. Wet cleaning is done via an integrated spray head. The gasket used for the lid can easily be replaced when needed, as it is not attached with adhesive. It is composed of silicone and is metal detectable. The feeding hopper is suitable for use in areas in zones 22 and 2 where there is a risk of explosion.
To avoid dust escaping when sacks are discharged, an aspiration process can be connected that starts when the lid of the feeding hopper is opened. The lid switch complies with safety requirements for applications up to performance level D.
