Milkshakes were first born in the United States, and there are mainly two types: "machine milkshake" and "manual milkshake". Traditional milkshakes are hand-cranked and are usually sold in fast food restaurants and cold food shops. The milkshakes in the shop are now sold, and customers have bought them now. In fast food restaurants, most of them use large floor-standing milkshakes, which generally sell vanilla and strawberry chocolate flavors. Although this milkshake is made by machine, its scale and packaging are not industrial products after all. Even if this milkshake is stored at room temperature, the storage period can be as long as half a year. Therefore, this new type of milkshake has quickly become popular in European countries because of its novel and unique drinking method.
