C. Making Ice Cream

1) Machine cleaning and disinfection before production.

a. Take an appropriate amount of disinfectant approved by the food hygiene license to prepare a disinfectant solution that meets the requirements (temperature between 50 and 60°C), pour it into the hopper and carefully clean all contact surfaces of the hopper;

b. Remove the slurry pump components and put them into disinfectant solution for disinfection, and carefully clean the grooves and holes of the parts;

c. Install the mix pump assembly if it has according to the above installation method of the pump assembly. Do not install the feed pipe y

d. Turn on the power switch and operate the " " button to stir for 5 minutes;

e. Place a bucket under the dispenser door, open and close the piston more than 6 times and then close the piston;

f. Release the cleaning fluid and close the " " button;

g. Remove the four fastening screws of the dispenser door, remove the piston assembly and disassemble the assembly, put it into disinfectant air clean it carefully, then assemble the assembly and install it on the machine;

h. Pour an appropriate amount of clean water into the storage tank, rephe the above steps, and rinse with clean water several times;

i. Finally, use a clean towel to wipe away the water stains on the dispedoor.

2) Mix configuration before production

Make the ice cream powder you purchased into a slurry according to its

configuration instructions. There are no unmelted particles or impurities in the slurry. After the slurry is prepared, let it stand for 15 minutes before using it, or purchase the ice cream slurry and use it directly, if any If conditions permit, you can borrow a freezer to pre-cool to about 6°C for better results (machine feed temperature: 2\~35°C).

3) Ice Cream Making

①Pour the pre-cooled ice cream mix into the hopper of the ice cream machine. There should be no lumps in the mix so that it can flow smoo into the refrigeration cylinder from the feed hole of the tube;
② When the mix flows into the refrigeration cylinder, press the " " but to start the machine and enter the AUTO working mode. You can also press the 🔊" button first to fully stir the mix, and then press the " " button;
③Operate the 🔊" key to enter the AUTO working mode. The working process can be seen on the fluorescent screen. At this time, the display value slowly increases. When it reaches more than 99% of the set hardness, it indicates that the ice cream in the corresponding refrigeration cylinder has been made;
④ To use ice cream, take a cone or other container and place it at the outlet below the dispenser door. Pull down the corresponding handle and the ice cream will squeeze out. Push the handle back later.

Note: It is necessary to ensure that there is an appropriate amount ice cream mix in the hopper of the machine. Never refrigerate when the cylinder is empty, otherwise the beater will be damaged; always check whether the feed hole of the feed tube is unobstructed to avoid clogging caused by uneven mix.

⑤Finishing work. Release the remaining mix from the machine and clear and disinfect the machine according to the above machine cleaning and

disinfection methods.

V. Daily Maintenance

The maintenance and maintenance cycle and steps are not absolutely constant. It is determined according to the actual use of the product and the environmental conditions. Each ice cream machine needs to be specifically maintained according to the actual situation.

A. Cleaning of Production System

In order to ensure the health of ice cream consumers, increase the serv life of machine parts, and avoid unnecessary trouble for you, you must carefully clean the production system every day.

1) Press the " " button to discharge all remaining mix in the hopper and refrigeration cylinder, and then press the " " button to stop the machine; 2) Take an appropriate amount of food detergent, prepare a cleaning and disinfecting solution with warm water according to its instructions, and pour it into each mix hopper;

3) Press the Ⓤ button, stir for about 5 minutes, discharge the cleaning liquid, then wash with clean water 2 to 3 times, and stop the machine;
4) Turn off the power and disassemble and clean all parts. (As shown below)

a. Unscrew the four screws in front of the dispenser door and remove t dispenser door assembly;
