Overrun Adjustment; Rerun - ELECTRO FREEZE GENESIS Series Operator's Manual

ELECTRO FREEZE Soft Serve Model GEN-5400

11.2 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.
You were supplied with three air meters,
each having 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
result in a 3-5% increase in overrun. Each
full size change 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!

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 with a lid.
2. Store in a cooler with a
temperature below 40
3. DO NOT prime the machine with
rerun. Always skim off with a sanitized
spatula and discard foam. Then combine
the rerun with fresh mix in a ratio of 50/50
and add to the mix container during
operation.

The mix will be a factor in determining
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.
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.
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.
