The biggest challenge in successfully cleaning spiral
freezers is trying to reach all the surfaces. Spiral freezers are
constructed with minimal clearances, making it hard to use traditional cleaning
techniques such as the spraying of liquid chemicals. The interior is too
tight to maneuver cleaning equipment properly and operate it effectively.
Cleaning every nook and cranny inside of a spiral freezer is a very difficult
task when taking into consideration all of the internal components, all of the
hard to reach crevices, the difficulty in maintaining the correct contact time
of the chemical being used, and the difficulty in the agent reaching all
surfaces.
Chlorine dioxide gas has been proven effective at
eliminating listeria from within spiral and tunnel freezers. ClorDiSys’
chlorine dioxide gas is made using a proprietary generation method and is
registered with the US EPA as a sterilant providing a 6-log (99.9999%)
reduction of all viruses, bacteria, fungi, molds and spores. As a true gas,
chlorine dioxide naturally fills the spiral freezer evenly and completely, and
with a molecule size smaller than the smallest organism, there’s no surface
that is safe for pathogens to hide. Gaseous CD is the only decontaminant that
penetrates water and decontaminates both the water and the surface beneath,
which is important for spiral freezers that typically have condensation issues.
One facility which produced frozen sausages had a persistent
listeria problem, resulting in consistent positive swabs. After one treatment
with chlorine dioxide gas, the facility was able to eclipse 16 weeks without a
single positive swab after testing 2-3 times per day. CD gas decontamination
has been written into a quarterly preventive maintenance schedule.
