6. Ice cream making method
1) At present in China the ice cream is usually made by mixing the ice cream materials with water.
Please mix them in strict accordance with the ratio as printed on the ice cream bag (Generally 1
kilogram of ice cream material should be mixed with 2.5-3 kilograms of purified water.).
2) Place down the mixed ice cream pulp for 15 minutes and then evenly pour it two the two
material cylinders on the top of the machine. It is required that the pulp cannot caking in order that
the pulp can smoothly flow into the refrigerating cylinder through the feeding hole of the puffing
tube.
3) Pull down the left and right handles in order to let the two discharge holes flow out 2-3 cups of
ice cream pulp in a natural manner. Then pour it into the top material cylinders to prevent water
freezing at the discharge mouth, for it will influence the making of ice cream.
4) Switch on the power supply. As the machine enters the standby state, press the “Cleaning” key
and let the machine run about 3-5 minutes. After that press the “Stop” key to stop the machine.
（6）
5) Press the “Auto” key. As the machine enters the refrigeration and moulding state, press the
“Soft or Hard” key to choose the hardness of the ice cream as you want (Notes: At the prior
cleaning state, you must closely observe the current hardness value displayed. If the current value
is displayed as 3.5, then the hardness of the ice cream should be set between 4.5-5.5. If it is
displayed as 4.0, then the hardness should be set between 5.0-5.5.).
6) When the actual measured hardness of the ice cream reaches the set value, the machine will
automatically stop operation and enter the standby state. At the time you can press the “SET”key
to set the time as required for the cycle of automatic refrigerating. The automatic refrigerating
cycle is set as 3-9 minutes. As you press the key every time, 1 minute is increased. Until it reaches
9 minutes, as you press the key again, the machine will return to the 3 minutes state. (Note: when
it is hot, you’d better set the stop time shorter and vice versus.)
7) Take one ice cream cone or cup and place it at the valve outlet. As you pull down the material
discharge handle, the ice cream will be extruded. After a while pull back the handle, and it is OK.
7. Maintenance and repair
To guarantee the health of ice cream consumers, improve the service life of the machine
components, and avoid unnecessary troubles, you must clean the refrigerating cylinder one time
every day.
1) The cleaning of the refrigerating cylinder
a. Press the “CLEAN” key to discharge all the pulp inside the cylinder. Press the “STOP” key to
stop the machine.
b. Add appropriate amount of disinfectant to the warm water. Then pour the mixture into the two
material cylinders respectively, each being with basically the same amount of solution.
c. Press the “CLEAN” key again and let the machine stir for about 5 minutes. Then discharge the
cleaning solution.
d. Clean the machine 2-3 times with clear water and then stop the machine.

stirring shaft and bellmouth seals, for often using vaseline can prolong the service life of the
components.
2) Body cleaning
Since the consumers require beautiful appearance, clean and sanitary machine, please keep the
appearance clean at any time. You can use the warm towel to scrub the body to remove the dirts
and spots, but avoid washing it directly with waer in case the appliance breaks down.
3) Condenser cleaning
After the machine works a period of time, the condenser will be covered with dusts, thus
affecting the heat dissipation and making the refrigerating effect worse (which embodies: the
output of ice cream drops in the same time or it is hard to take shape.). Please have it cleaned one
time every three months (If the working environment is poor, please clean it once every month.)
by professional workers. Before clean the condenser, please switch off the power supply and note
not damaging the condenser fins.
4) Adjustment of the belt
After the machine works a period of time, the driving belt of the stirring system may be pulled
longer, so timely adjustment to the belt should be made by professionals. Before adjustment, you
must cut off the power supply. Then dismantle the enclosure plates to adjust the belt tension nuts
and ensure appropriate tightness. If you still feel the belt is still to loose after adjustment, please
replace it with the same typed belt.
