CIP-Nozzles:
We can’t talk CIPable sifters, without also talking CIP nozzles!
Alvibra offers integration of basically 2 different types of CIP nozzles. Integration also includes careful and technical consideration of the nozzles positioning for ideal sanitation. Nozzles are positioned both under and above the screen and the number of nozzles depend on several factors.
Replaceable nozzles are only in place and in use while the sifter is not in operation / in cleaning mode. After completed sanitation, nozzles are replaced with blind-caps.
Retractable nozzles stay in place all the time both during screening operation and during the sanitation process. Nozzles open (pop-in) for cleaning by the CIP water pressure or by a separate pneumatic air-pressure. Proximity switches for open / close detection is an add-on.
Consequently, the Alvibra retractable nozzles are designed to withstand the vibrations 24-7. The Alvibra retractable nozzles are vibration resistant, pop-in/pop-out type and features a wide spray pattern with impact cleaning for removal of even difficult powder build-up.
Customers often provide hose connections to each of the Alvibra nozzles however, to make integration easier, Alvibra also offers a single connection point solution.
The Alvibra sifter series range up to 7,5 m2 screening area. To reduce the sifter height and ease the handling of screens, the largest sifters are made with 2 screens instead of 1.
