10.1 Dairy Queen
®
Mix
10 General Information
Two measurements of product consis-
tency 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
about the quality of the product being
served and the operation of the freezer.
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 tem-
perature. In any of the above cases,
always measure temperature and
overrun to see if they fall into normal
operating ranges.
