Yogurt & soft ice cream machines offers the following advantages
1.Minimum noise and refreshing cooling system
With a high efficiency and low noise motor, we can provide minimal noise from
the refreshing cooling system.
2. MICOM control method
Use of an artificial intelligence control system achieves an optimal cooling system.
3. Pasteurization function implemented
A low-temperature pasteurization process is implemented for heating products at 68 ℃
for 30minutes to supply sanitary ice cream products the spoilage of materials.
4. Defrost function
The soft ice cream inside the cylinder can be defrosted to liquids
5. Touch sensitive LCD display
Push button design for easy operation.
6. Convenient washing system
Feedwater lines are directly connected to the system; the model with pasteurization functions
allows using boiling water when cleaning the cylinder and the storage tank to facilitate
the cleaning of the system.
7. Patented texture & taste control system
By allowing separate speed controls for producing and projecting soft ice-cream,
you can have the best ice cream quality.

Check prior to use
【 Make sure to check them prior to use ! 】
This product is for 230V, 50Hz / 220V, 60Hz.
Install it independently in an earth leakage circuit breaker with more than 20A
and provide an external grounding.
(Ask a qualified electrical technician for the installation.)
The power cable should be connected before the product can be operated normally.
●
Do not block the air vent.
The air suction and discharge should be facilitated so that the cooling performance can be optimized.
Upper discharge

●
Periodic filter cleaning(Once a week). - Air cooled type
For better taste of soft ice cream, do not miss the filter cleaning time.
●
Clean the condenser once a month. - Air cooled type
It is recommended to clean the cylinder, the mix tank, the impeller, the dasher,
the carburetor, the piston every day.
Clean the condenser at least once a month or more often.
●
Pasteurize it at least once a day.
The cylinder, impeller, dasher, or piston inside the product makes a contact
with the ingredient, so you should clean them once every day.
If you intend to leave it unused for a long time, wash it and turn off the water supply

If pasteurization is not done every day, and the ingredients
are stored at a temperature below 5℃, after 2 or 3 days,
it can cause deformation or decay.
To prevent decay and to maintain the initial refreshing
soft ice cream ingredients, then you should heat it at
68~70℃ for more than 30minutes every day.
This method is called pasteurization and is known as
“pastea pastea.”The function allows you to keep the
