Ice cream uses drinking water, milk, milk powder, cream (or vegetable fat), sugar as raw material and then add some food additives. It is made by mixing, pasteurizing, homogenizing, aging, freezing, hardening etc. processing.

According to the raw material, the ice cream can be divided into milk cream ice cream, yogurt ice cream, fruit and vegetable ice cream etc.

Industrially made ice cream is generally injected with a mixed ice cream liquid into a mold placed in an ice-salt mixture. During the melting process, the ice-salt mixture will absorb a large amount of heat and can easily freeze the prepared liquid into ice cream.
