Cattle Feed
Animal feed comes in many forms. Pelleted or mash feeds are popular in
the market. Both products share a similar production sequence until
the mixing process. pelleted feed needs to undergo pellet mill,
cooler, and sifter after the mash is prepared.
Mash feed is a form of a complete feed that is finely
ground and mixed so that animals or birds cannot easily separate the
essential nutrients. The purpose of feeding mash diet is to provide a
well-balanced diet, give greater growth unification, less
death-incurred loss also feeding mash feed is more economical. When
producing mash feed, the material undergoes pre-grinding before mixing
and packing.
Pelleted feed is the continuation of mash
feed. The purpose of pelleting is for easy transport and feeding. The
nutrient value in every pellet is the same, so farmed animals will
consume all the good nutrients incorporated inside the pellets.
Raw Material
The raw material for cattle feed consists of coarse and powdery
material

Pre-grinding
Optional step for coarse material.
Pre-grinding will lower the
energy needed for fine grinding.
Daily Tank Storage
Daily tank storage will contain the material needed for production
that day.
Some material from the silo will be placed in this daily tank
before entering the flow of feed production.
Dosing and Weighing
The material will be dosed based on the formula.
Post-grinding
Post-grinding is the final size reduction in the system.
It is common to use fine grinder in this process.
Mixing
In this step, trace ingredients such as vitamins, minerals, and
other liquid materials will be added.
Powder Feed (Mash Feed)
Pelleting
Pelleting starts with pre-conditioning, adding steam to further
hydrate, and cook the material before entering the pelleting chamber
to be formed into pellets.
Cooling
Cooling utilizes ambient air to cool down the hot pellet from the
post-conditioner (or dryer).
Thorough cooling is needed to prevent condensation inside the
packaging.
Pelleted Feed
Crumbling
In animal feed production, it is common to crumbler the feed.
This particle reduction is needed for easier consumption in
smaller animal or poultry
Packing
Packing gives protection to the pellets and also give easiness to
handle and transport to customer's hand
Pelleting process description for cattle feeds
Raw material silo and intake systems
Corn, soybean, rice, and other macro ingredients are stored and conveyed
to an individual silo.
Dosing and weighing are used
for dosing the raw materials based on the formula.
Grinding system
When required, coarse or fine grinding will be done to reduce the
particle size.
Mixing system
Depending on the formulation some liquid, fat, or molasses will be added
to the mixer. The well-mixed mash can be directed to the finished
product bins for bagging or carried away by trucks in bulks when
producing mash feed. The mash feed can also be directed to the pellet
forming machine.
Pelleting with Pre-conditioning
Well-mixed mash is fed to a pre-conditioner where the mash will be
heated either by steam or electric heater, to kill salmonella and other
harmful bacteria. Pre-conditioned mash feed is then pelleted.
Cooling
The counterflow cooler is used for cooling pellet and extrudate. Warm
(hot) pellets get into the cooling chamber, the suction fan will
transport out the air inside the chamber, and fresh ambient air will
enter the chamber from the bottom, promoting pellet cooling action. When
pellets are accumulated and touch the high-level limit sensor, a
pneumatic discharge swivel valve will operate immediately to discharge
the products. Counterflow air heat exchange ensures to achieve high
cooling efficiency.
Impurity and dust sieve
Pellets are conveyed through a sieve to remove impurity and deformed
pellets. Fines and deformed pellets are recycled back to bins before the
pellet mill. The sieved pellet of different sizes is stored in
individual bins.
Bagging and sealing system
Finished pellets will be placed in bags or other transportation vessels
to the reseller or customer site.
Pellet crumbling system
IDAH crumbler series is designed for high capacity and highly efficient
particle reduction. Every crumbler is equipped with the feeder on the
top, to control the throughput of the product. The roll gap is easily
adjustable to achieve the required granulation.
Features and Benefits of IDAH Process Design and Equipment
IDAH firmly believes in a strategy of design fit for purpose. We
recognize the constraints our customers face with rising ingredient
costs, energy costs, and overheads costs, yet in the face of these
challenges, it is still expected that high-quality products be supplied
into a very competitive market. Our design philosophy is to work
continuously to refine and improve processes and equipment to maximize
the success of our customers. The following describes some of the
features and benefits resulting from this philosophy.
Heat sensitive formulation
Piglet feeds formula usually contain milk powder or sugar which are
heat-sensitive ingredients. When exposed to heat, milk powder and sugar
can form browning Maillard Reaction which will result in brown color. A
low-temperature pre-conditioning is the key to success with mash at
outlet attains temperature no higher than 50 °C.
Other pig feed formulation
Formulation usually contains a high amount of grains: barley, wheat, or
corn. With different proportions of those grains, the parameters of the
pellet mill operation vary. Usually, steam is used to pre-condition the
mash. In Pig feed, molasses may be added during mixing or after the
pellet is formed.
