15.2 Overrun Adjustment

NOTE: Each person who operates the
freezer should know what overrun is
and how to calculate it.
Overrun is regulated by the air meter. The
four air meters supplied with the freezer
each have a different size orifice. The
smaller the hole and number, the lower
the overrun. The larger the hole and
number, the higher the overrun. Each
half-size change of the air meter number
will change the overrun 3-5%; each full-
size change of the air meter number will
change the overrun 8-10%.
The orifice or hole in this air meter must
be open at all times. It is the only source
of air into the freezing cylinder. Check this
daily!
The mix will be a factor in determining

Rerun

Rerun is product that has been drawn through the freezer into a container and has
melted down to be re-processed. If local health codes permit the use of rerun make
sure to follow these procedures:
1. Store rerun mix in a clean,
sanitized container.
2. Store in a cooler with a
temperature below 40
3. DO NOT prime the machine with
rerun. Always skim off and discard foam.
Then combine the rerun with fresh mix
in a ratio of 50/50 and add to the mix
container during operation.
4. Once a week run the mix as low
as possible and discard after closing. This
will break the rerun cycle and reduce the
possibility of high bacteria and coliform
counts.

the amount of overrun you will be able to
achieve. Some mixes will accept more air
than others, thus affecting the size of air
meter you can use. Test to see which air
meter will give you the best overrun and
the best product. Run each air meter for a
few hours until you decide.
You may have a slightly higher overrun
when you first start up the machine.
After the machine has run long enough
to dispense at least one full cylinder of
product, you will have the overrun that
the machine will hold the remainder of
the day. Contact your mix supplier for the
recommended amount of overrun for each
product used.
NOTE: Rerun product is unable to accept
the same amount of air as fresh product.
As a result, the quality will be affected and
product may appear grainy and icy.
