ISHIDA’S GENTLE SOLUTION FOR
STICK SNACK PRODUCTS
Ishida’s ability to devise universally
available solutions for specific products and
applications has been underlined by the
introduction of a new multihead weigher into
its Sector Solutions range. The CCW-RV-216W-
1S-20-SS-STK1 is a standard model designed
to handle the particular challenges of stick
snack products at high speeds - up to 120
packs per minute - with no loss of accuracy or
product quality.
Pretzel sticks - in salted, plain, seeded and
filled varieties - are a hugely popular snack
in countries such as Germany, Turkey and
the Middle East and are a growing market
in many other areas. Their fragile and dusty
nature makes them particularly difficult to
pack in an automated weighing system.
The Ishida stick weigher has been designed
for gentle handling of the fragile stick snacks
to minimise the potential for breakages. It
ensures optimum flow of the sticks, with
reduced angles throughout, a low-profile

inlet chute, convex dispersion table, and
waterfall ends for smoother transition of the
long products into the pool hoppers. Special
electrostatic polished contact parts reduce
dust build up throughout the weighing
process.
To enable maximum flexibility in handling
different pack sizes, from 35g to 250g, the
weigher is also supplied with special hopper
inserts. These align the sticks and keep them
upright, ready for a clean transfer.
Following initial weighing, each batch of
sticks used in the combination is held in
a special shutter hopper mid-way down
the discharge chute to ensure they remain
correctly aligned, ready for discharge into the
bag. The correct combination of product is
then transferred via a high-speed discharge
chute which also incorporates an inner guide
insert to maintain alignment down to the next
section.
