So how is such a small can of yogurt packaged?
· Preparation and sterilization:
Before filling, yogurt needs to be fermented, sterilized and cooled. After the milk is sterilized, lactic acid bacteria are added for fermentation, and then cooled to the appropriate temperature.

The containers (such as plastic cups, bottles or bags) in which yogurt is packaged are usually cleaned, sterilized or exposed to ultraviolet light before filling to ensure hygiene. Automated equipment can usually clean and sterilize multiple containers at the same time.
· Choose a suitable cup filling machine:
1 Yogurt is transported from the storage tank to the filling machine through a pipe. The filling machine is usually equipped with multiple filling heads, which can fill yogurt into multiple containers at the same time. When filling, ensure that the amount of yogurt in each container is consistent to avoid too much or too little.
