Choosing the right tool for the right task.

With pet ownership at an all-time high, the demand
for innovative pet food products continues to grow. In
response, pet food manufacturers are closely watching
food industry trends to forecast the future demands of
pet food customers who are looking for high-quality
products combining nutrition and other health-oriented
properties, according to Dave Carney, petfood market
segment leader, B├╝hler, Lake Bluff, Ill.
" Pets are valued members of the family, and feeding
them a minimally processed, whole food, human-grade
diet is increasingly important to people and their pets, "
said Carmen Velasquez, vice president of marketing, The
Honest Kitchen, San Diego, Calif.
Such a mindset is producing pet food trends that mimic
those in human food including the use of more highend
ingredients like fresh meats. Previously limited to
mainly semi-moist or moist types of pet food, interest is
spreading to the dry pet food products known as kibble.
These products look to meet the varied needs of pets
with formulas for different life stages including young,
adult and senior animals, small and large breeds, and
active and overweight pets. Increased demand for pet
foods free of common food allergens such as soy, wheat
and corn find producers looking to the natural diet of
wild animals with formulations including novel and sustainable
proteins, vegetables, and good sources of fiber.
The production of kibble employs a process of extrusion
followed by baking and drying and the option
of enrobing the product in mixtures of fats, flavors, vitamins
and minerals before packaging. Processors can
choose from cold forming extruders, pellet mills and
cookers to extrude and portion materials before drying,
according to Jeff Zeak, national development manager,
bakery, Reiser, Canton, Mass.
Evolutions in baking and dehydration drying machinery
offer hybrid oven dryers in combinations of convection
impingement technology (variable heat and air
velocity), humidity control (injecting steam), and radio
or microwave technology (heating, cooking and drying
from the inside out).
Freeze-drying is another method for drying kibble to
a lower finished product moisture content.
Evolving processes
As calls for baked kibble continue to grow, Reading
Bakery Systems, Robesonia, Pa., is finding more customers
in search of ways to reduce dollars per pounds. For
many, the answer is found in automation, sizing the feed
system, building the dryer accordingly to match the oven,
and allowing customers to run bigger systems with fewer
employees while achieving a more consistent product.
To improve kibble product consistency and throughput
efficiency, Zeak recommends pre-blending dry ingredients
as well as pre-mixing dry with wet ingredients and
pre-heating mixtures to help processors improve ingredient
dispersion, solubility and hydration. Reiser recommends
a preconditioner mixer blender for the delivery of
homogenous product mixture to the extrusion process,
whether in the form of a pellet mill, cooker or a Vemagbrand
cold forming extrusion machine for processing.
