Batching and
mixing systems
Designing for the addition of
micro-ingredients and liquid ingredients
by Fred Fairchild

In previous articles we have determined batching and mixing cycle times, capacity and size of feeders from the ingredients stored in the overhead bins, batching scale capacity,
and mixer capacity for the two formulations we introduced
in the May 2018 article.
In this article we will complete the design of the batching and mixing system for the addition of the micro-ingredients and the liquid ingredients needed to complete the
formulations being produced.
MICRO-SYSTEM SELECTION
A micro-system is a small self-contained batching system
with compartments for the individual ingredients added
to formulas in small amounts. Each compartment usually
holds two to three bags of an ingredient. Each compartment has a miniature screw feeder that meters each ingredient into a common long-scale hopper that discharges into
a drag conveyor that transfers the micro-ingredient batch
directly to the mixer.
The micro-system weighs up the micro-ingredients while
the overhead bins ingredients are being batched in the large
batching scale hopper.
When called for in the mixing cycle, the micro batch
hopper discharges into a drag conveyor that takes the batch
of micro-ingredients to the mixer. A slide gate should be
installed on the discharge of the transfer conveyor that is
opened only when the micro batch is being delivered to
the mixer.
This eliminates air pressures and surges that occurred in
the mixing system so they do not affect the micro-system
when the micro-ingredients are being weighed.
A second type of micro-system has each compartment
mounted on its own scale, which operates as a loss-in-weight
46

feeder. With this system, each needed ingredient is measured
individually into the transfer conveyor to the mixer.
One advantage of this system is that an inventory of the
amount of ingredient in each compartment is always available.
With the formulas we are using for this series of articles,
the micro-ingredients used are Ameribond 2X (dry pellet
binder), Tylan 10 (antbiotic 10g/lb), Swine Vit/TM premix, salt, Pig Krave-Flavoring agent, Ronozyme CT (ProBiotic), ENDOX Dry (antioxidant), SMI Pellet Pal (pellet
binder), Broiler Premix, Lysine, MonoCal Phos, Salinomycin and RonozymeCT (probiotic), for a total of 13 microingredients.
For this facility, I would recommend a micro-system
with a minimum of 14 to 16 compartments.
In some cases, the amount of a micro-ingredient needed
