if the ambient temperature is at 75°F. The times will vary depending on the ambient temperature (a higher ambient tem-
perature requires more time for the product to cool).
Viscosity Setting
The control system includes a function to select the desired product viscosity. This function is referred to as “Viscosity Set-
ting”. There are selectable viscosity ranges from 1-9. The higher the number selected, the more viscous the frozen product
in the barrel becomes. This increased viscosity is achieved by freezing the product in the barrel to a lower temperature
thereby increasing ice crystal size/growth. As the ice crystal size increases, however, there is potential for product quality to
diminish.
Cornelius recommends that the viscosity settings be set at the lowest possible setting to achieve the desired drink quality.
In most typical installations using a sugar-based syrup, acceptable drink quality can be achieved by programmed viscosity
settings in the range of 3-5 for Viper.
Diet FCB syrups freeze much more readily than sugar based syrups, so the viscosity setting should be selected at the mini-
mum value available (which is 1 or 2 for the Viper).
