The ice cream manufacturing process involves mixing ingredients, pasteurization, homogenization, aging, freezing, and packaging.

• Ingredients such as milk, cream, sugar, and flavorings are mixed together in a large vat.

• The mixture is then pasteurized to kill any harmful bacteria.

• Homogenization is done to break down the fat molecules and create a smooth texture.

• The mixture is aged to allow the flavors to meld together.

• The mixture is then frozen using a continuous freezer.

• Finally...read more
