FOOD SAFETY
ELIMINATING PATHOGENS
 Sormac's Pulstar washer.
that germicidal effect was highest between 240 and
280 nm. At this wavelength, the light disrupts the DNA of
microorganisms, inhibiting them from multiplying. The
study, which was conducted at pilot-scale first and then
larger scale, garnered positive results when UV-C was
used correctly.
UV-C disinfection offers processors three possible
benefits. It has the capacity to reduce the probability of
cross-contamination where pathogens are transferred
from one product to another. Because the end product is
microbiologically " cleaner, " it's possible to extend product
shelf life. UV-C disinfection may also offer financial savings,
as less fresh water is needed in the process.
Kronen improves hygienic design and overall
performance
Processors don't have time to fuss with hard-to-clean
machines. They want to minimize downtime and get
sanitation crews to get in and out quickly. To address this
concern, Kronen focuses on quick and easy disassembly
and re-assembly methods for cleaning.
Speed isn't always desirable, though, especially in washers
designed for leafy greens.
" One of the downsides of most washers is dwell time, "
said U.S. sales manager Russell Quandt. " The product has
to be in contact with the sanitizing solution for a very strict
amount of time, and most washers run too fast for that. "
To address this issue, Kronen designed a new washer for
vegetables and leafy greens: GEWA 3800 RT.
The GEWA 3800 RT washer utilizes helical-style water
agitation. Instead of running through the washer, the
discharge is blocked for a set amount of time so product in
the wash tank can be thoroughly agitated and separated,
allowing for complete exposure to sanitizer. The timer can
be changed to suit customer specifications.
" It takes the guesswork out from having operators decide
how long the product's been in the solution, " said Quandt.
Kronen is also constantly working to upgrade the hygienic
design and performance of their washers, he added. They're
doing this by eliminating harboring points, including square
corners, steel tube, and wire and cable management systems.
They use continuous welds instead of stitch welds, as wall
as standoffs to eliminate surface-to-surface connections. All
surfaces in the washers are sloped so water cannot pool and sit.
" In the machine industry, it's easy to make a machine
complicated, " Quandt concluded. " It's more difficult to make
them simple, and Kronen has been very good at designing
machines that work extremely well with the least amount
of parts. "
Kronen works with small to medium-sized processors
and customizes equipment to customer specifications.
