DEPOSITING

itself. Larger openings, like larger piping, will help with
thicker, stickier batters.
" Carefully designed large openings and smooth transitions
of Unifiller depositors and nozzles guarantee efficient
and delicate handling of batters to ensure that batters
are deposited with consistent integrity and accurate
portions, " Ms. Bal said.
For cutting off the batter once the appropriate weight is
metered, Hinds-Bock uses auxiliary positive cut-off spouts.
These are air actuated nozzles that act like a scissor.
" It opens and closes the nozzle and shears the product
off by force and cutting it off cleanly by opening and
closing the nozzle, " Mr. Gregg said. " It helps us handle
sticky gluey gluten-free products. "
Hinds-Bock also offers individual metering pistons to
ensure each deposit in the depositors' metering piston
chambers are correct.
The proper nozzle opening also preserves the expensive
inclusions in better-for-you products like blueberries
and nuts. These inclusions can be delicate and, when
Servo-controls improve depositing accuracy and efficiency and
help fill the workforce gap.
Unfiller
broken, can either smear into the batter, discoloring
them or destroying the pieces' integrity that makes them
so appealing in the first place.
" Many batters include particulates, such as fragile
blueberries, particulates that need to remain suspended,
or heavy batters that are stiff and include a high
number of particulates, " Ms. Bal said. " Most Unifiller
systems can handle those through larger ports, attachments
that allow a cleaner, intrusion-free deposit,
the use of hopper agitators and more. Higher egg content
batters can also be easily portioned through depositors,
although processes prior to depositing may
need to be adjusted. "
AMF Tromp designed its Unimac Depositor to handle
a wide range of different batters, and therefore it offers
easy-to-change depositing heads as well as interchangeable
nozzles and dies. This allows bakers to choose the
proper nozzle opening for the batter being deposited.
The right nozzle may be the key to an accurate and
clean portion of batter, but bakers should not overlook
flow. A proper flow may be critical to product
consistency, but it's also key to a consistent, accurate
deposit. While speed is a baker's friend when cutting
off the deposit, slowing down will aid in accuracy
when it comes to flow.
" Another thing that will help with accuracy is slowing
down the speed that we draw the product into the machine, "
Mr. Gregg explained. " If you draw a thick product
into the machine too fast, you can draw in air instead
of all the product and the deposit will be inaccurate. "
This extra air will throw off weights. To combat
this, controls on Hinds-Bock depositors have slow
suction flow to gently pull in thick batters without introducing
air.
As bakers try to incorporate new products into
their batter lines, they need equipment that can accommodate
changing needs. With servo technology
and proper equipment design, bakers can adjust to the
viscosity changes that come with these formulations
and still deliver products that meet expectations.
