If the temperature is too low (overfreezing) while operating the product, issues may arise such as interrupted
operation or damage on a part or the power delivery axis. Some issues may involve too much noise
or burning smell due to friction, and foreign substance may come out with the ice cream due to damage
of a part inside the product.
Refer to the main causes of overfreezing and operate the product safely.
1. We highly recommend using the proper liquid ingredients. If you intend to use powder
ingredients by mixing it with water or milk, be sure to follow the mixture ratio suggested
by its manufacturer.
(This ice cream machine should use properly mixed ingredients in order to produce
good-quality ice cream. Please apply additional caution if you intend to use powder-type
ingredients, since it tends to precipitate or gets separated over time from the water or milk,
which results in overfreezing and troubles with producing ice cream and operating the product.)
2. Even if you use the proper liquid ingredients, adding an additive to it or arbitrarily
adjusting the dilution ratio may result in poor quality of the ice cream or overfreezing.
We do not provide warranty or assume responsibility for issues related to the ingredients.
Be sure to check and follow the dilution ratio.
3. The powder ingredients must be mixed manually and slowly.
If the powder ingredients is mixed fast using mechanical means, too much oxygen will be
mixed into the final ingredients, which easily causes oxidization and coagulation over time.
In this case, the ingredients will become lumpy like pieces of tofu, causing troubles
with the supply of the ingredients and overfreezing.
4. Overfreezing may also occur due to the poor supply of the ingredients to the drum
which the ice cream is produced. Be sure to check the amount of the ingredients, so that
the product is always operated with sufficient amount of ingredients. Due to the nature
and viscosity of the ingredients, it may easily get lumpy and block the carburetor
(mixing valve) hole through which the ingredients is supplied to the drum. Be sure to remove
and wash the carburetor frequently.
5. If the product is not expected to be used for an extended period of time, ice formation may
occur in the mix tank(hopper) due to the extended waiting time, which causes poor supply
of ingredients; repeated production process during the waiting time will facilitate the separation
of fat. In this case, the ice cream will become too thin, or overfreezing will occur. Be sure to
operate the product on a regular basis even when there is no demand so that the waiting time
of the ingredients can be minimized.
6. Repeated use of the ingredients will result in the poor quality of ice cream and overfreezing.
When intending to clean the product, refill with new ingredients for re-start.
