handle the wide variety. All of the downstream processes
like extrusion and drying perform better if you
provide them a consistent, quality input. "
Batching options
Modern batching systems are designed with factors
such as accuracy, reliability, traceability, flexibility and
food safety in mind.
" Due to the increased food safety regulations and
requirements to adhering to exact ingredient percentages
in a given pet food recipe, the use of high accuracy
LIW [loss-in-weight] batching using gravimetric screw
feeders is quickly becoming the most reliable batching
device of choice, " Nowak said. " LIW batching utilizing
Coperion K-Tron high-accuracy screw feeders provides
a significant accuracy and process time advantage over
traditional GIW [gain-in-weight] batch techniques.
LIW batching is used when the accuracy of individual
ingredient weights in the completed batch is critical or
when the batch cycle times need to be very short. In
addition, LIW feeding affords broad material handling
capability and thus excels in feeding a wide range of materials
from low to high rates. "
" There are several different
types of batching systems, "
added Joe Lewis, marketing, Sterling Systems &
Controls, Inc., Sterling, Ill. " These include semi-automatic
hand prompt/add batching systems, semi-automatic
self-contained 'kitchen type' batching systems,
and automatic batching systems. "
Utilizing different systems and features allows pet
food and treat processors to fine-tune the batch process
from start to finish. Options include manual or automatic
batch delivery, various ingredient storage methods,
and integration to the ERP system to communicate
production schedules and ingredient usages.
" Most modern batch controls have dozens of features,

but a couple of useful ones for pet food are an order
grid and automatic bin level checking, " Ensch said. " An
order grid includes order number, formula name, the
amount of material to be produced, the required date,
destination bins and comments. The grid can have orders
entered direct or interfaces with your ERP system.
Automatic bin level checking has the system check bin
levels of each ingredient in a production run prior to
starting the batch. The system will alert the operator of
any insufficient ingredients.
" Another useful feature is production usage tracking

and inventory management with lot code tracking, "
Ensch added. " This allows the batch system to track
material used for each production run, batch, and track
respective lot codes for ingredients. Statistical process
control (SPC) charting is one more feature that's great
for fine-tuning the batch process. A system tracks the
production data to the level to produce statistical process
control charts. Being able to understand when a system
is in control or out of control and having the data
to either troubleshoot it or reduce variation for greater
accuracy can change your business. "
Product quality
There are several ways in which batching systems can
impact product quality.
" Vacuum conveying systems help to provide the right
amount of ingredients or final products to the next processing
or packaging step, " said Andrea Bodenhagen,
communication and content manager, Piab Vakuum
GmbH, Butzbach, Germany. " Thanks to the closed system,
it also provides a dust free environment and protects
the product from contamination. While the pet food industry
is often still using mechanical or manual material
handling, vacuum conveying systems are state of the art
in the pharma and food sector. Pet food manufacturers,
