The HSF spray nozzle is an innovation by Glatt for fluid bed and spouted bed processes.
"HSF" stands for hygiene and safety by fixed installation.
Hygienic design and CIP-ability are important for applications in the food and pharmaceutical industries. All industries will profit from the easy cleaning (WIP) and
simple handling.
Can be retrofitted to existing equipment.
Hygienic design
Hygienic design, according to EHEDG-guidelines, is the first requirement for cleaning in place (CIP).
The HSF-nozzle of Glatt has only smooth, round surfaces in contact with product and atomization air.
There are no possibilities for product to remain in gaps or along edges. After flushing both lines -
liquid and atomization air - with cleaning water, product will be easily flushed out with no residues
remaining, leaving the nozzle clean for accurate spraying.

Safety
Explosion protection is crucial for fluid bed and spouted bed processes, since many powders form
potentially explosive dust-air mixtures.
Up until now, there has been a risk when changing the spray nozzle during the process, because the
processing chamber needs to be opened. The new nozzle remains in the equipment, even when changing the
nozzle, since only the liquid insert needs to be changed.
The outer shaft stays in the equipment; the only opening is the small hole where the atomization air
enters the process - too small to allow any explosion to propagate.

Fixed installation
Fixed installation means very easy handling. The nozzle can remain in the equipment.
When inspection of the nozzle is required it can be easily and quickly dismantled.
It consists of only five parts which are screwed together.
