11 General Information
Two measurements of product
consistency are temperature and
overrun. Several observations can
be made by looking at and tasting the
product, but actual measurement of
temperature and overrun provides precise
information concerning the condition
of the product being served and the
operation of the freezer and the mix
transfer system.
Standard Dairy Queen
®
product should be
between 17° and 19°F (-8° and -7°C). It
should have an overrun of 40 to 45%. Its
appearance should be “dry” and appear
much like silk. If the product appears
“wet” or “slick” then it is usually an
indication that the temperature is too high.
If the product appears pockmarked and
soft, it may be an indication of too much
overrun. If the product appears grainy
and hard, it is an indication of either too
low overrun or too low temperature. In
any of the above cases, always measure
temperature and overrun to see if they fall
into normal operating ranges.
