Baking
Not surprisingly, utility usage is a
key focus when calculating ROI in
baking applications. Technology
improvements have reduced gas
usage by as much as 40% in newer
oven systems, according to Sam
Pallottini, director of biscuit,
cookie and pet treat equipment
sales, Reading Bakery Systems,
Robesonia, Penn. Consistent temperature and airflow also bakes
product more consistently, avoiding
burnt edges or underbaked centers
thus reducing product waste.
Continuous mixing offers cost
savings and efficiency benefits as
well. With continuous mixing, the
product load going into the mixer
is always the same so the mixer
can run at constant speeds.
" Continuous mixing requires
constant amp draw and requires up to 30% less electricity, "
Pallottini explained. " On top of
that, you are mixing in less ingredients at a time, which takes less
energy to produce a consistent
product. Continuous mixing also
enables you to have a lower-cost
dough feed system to the forming
machine because you are dealing
with smaller incremental batches. "
Another benefit is continuous mixing helps to fine tune the
moisture level of a product prior to
forming and baking. This enables
processors to lower the moisture
of the product going into the oven,
which reduces the work needed by
both the oven and dryer.

Packaging
An added value of packaging that
is hard to quantify is the impact of
the packaging on consumers' purchasing decisions.
Research suggests that " consumers will pay more for products
that look better, perform better,
and especially provide improved
functionality like easier opening,
reclosability, improved dispensing,

more portability, better storage
and other improved features, " said
Sal Pellingra, vice president, global application and innovation,
ProAmpac, Cincinnati.
Derek Lennox, vice president
of sales, pet and animal nutrition,
ProAmpac, pointed out that flexible packaging materials deliver
significant savings by using less
plastic compared to rigid packaging, and also achieve the sustainability goal of reducing raw material consumption.
" On a relatively more important total cost basis, flexible packaging requires less freight when
filling up a truck to ship empty
packaging to a processor, " Lennox
added. " It also has less weight and
is conformable for shipping and
distribution after filling. This is
becoming more important as ecommerce grows. "
When shipping products directly to consumers, flexible packaging costs less, requires less protective packaging and is damaged
less than rigid packaging, according to ProAmpac.

Continuous mixing in baked pet
product applications uses up to

30%

LESS
ELECTRICITY.

Analytics
Overall equipment effectiveness
(OEE) metrics that provide visibility upstream and downstream
from a piece of equipment allow
processors - and the suppliers of
that equipment - to confidently
and accurately diagnose issues
when they occur, which represents substantial savings.
" These kind of OEE metrics
allow you to identify issues not
just more easily but with confidence that you have located the
problem because you have data
to map over the course of time, "
Hanrahan said. " It gives you a
A continuous mixer can provide added
product benefits and cost savings
throughout a baking system.
