Ice cream, also known as ice cream, is a sweet food made of frozen milk and one of the common foods in summer. In its simplest form, ice cream is a kind of cold food mixed with ordinary food (milk, cheese, cream, etc.). ) with some desserts and other seasonings. After mixing them together, it is necessary to lower the ambient temperature to a very low temperature to ensure that a softer form is formed instead of large ice cubes. Generally, industrially manufactured ice cream is made by injecting mixed ice cream liquid into a mold placed in a mixture of ice and salt. In the process of melting, the mixture of ice and salt will absorb a lot of heat, so it is convenient to freeze the prepared liquid into ice cream.
