Preferred applications
The hygienic design 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, drums or similar receptacles.
Design
The feeding hopper is available in two different grades of stainless steel with a roughness depth of < 0.6 µm or < 0.8 µm depending on the surface finish. The radii on the inside of the feeding hopper are greater than 50 mm and can be cleaned leaving no residue. Wet cleaning is carried out with the integrated jet cleaner. The gasket used for the cover can easily be replaced as required, as it is not attached with adhesive. It is made of silicone and is metal detectable. The feeding hopper is suitable for use in zones 22 and 2 areas 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 cover of the feeding hopper is opened.
The cover switch is suitable for use in safety applications up to performance level D, such as shutting down downstream dosing units.
The sack support can be folded down or completely detached. The support feed are hygienically designed with no visible thread.
