Description

Liquid milk supply device and self-service coffee machine

Technical Field

The invention relates to the technical field of self-service coffee machines, in particular to a liquid milk supply device and a self-service coffee machine.

Background

Coffee blended beverages are typically composed of freshly ground espresso and milk flavor ingredients, and commercial cafe coffee machines typically function to deliver the coffee blended beverage.

In the related art, it is common to blend with a formula of instant milk powder to form a milk-flavored ingredient, followed by the production of a coffee-blended beverage. The instant milk powder is conveyed to a mixing cavity by a conveying screw during production, and is mixed with hot water to form hot milk flavor liquid ingredients, and the hot milk flavor liquid ingredients are conveyed to a coffee cup below a drinking outlet of the coffee machine through a pipeline and are mixed with coffee liquid ingredients to form the final prepared beverage. However, the instant milk powder formulation has a low milk reducing degree, so that the flavor quality and taste of the coffee blended beverage prepared by the instant milk powder formulation cannot be compared with those of the product using the liquid milk raw material. Meanwhile, some coffee blended beverages need to be blended by using foamed hot milk, and ingredients formed by the instant milk powder in the formula cannot be compared with liquid milk raw materials in shape.

In view of the above, the related art proposes a scheme for providing liquid milk to prepare a coffee blended beverage, and specifically, the liquid milk is stored in a manner that an open container or an open container inside a refrigerator is covered, and the liquid milk raw material is delivered to a corresponding heating and foaming device of a coffee machine in a manner of being extracted through a pipeline, so as to form hot milk ingredients, and then the hot milk ingredients are delivered to a coffee cup below a drinking outlet of the coffee machine and mixed with the coffee ingredients to form a final blended beverage. However, since many places where the self-service coffee machine is applied are semi-open spaces, the surrounding biological environment is complex, the risk of invasion of external microorganisms into raw materials cannot be isolated in an open or semi-closed mode, and the food safety risk is uncontrollable. Meanwhile, according to the relevant regulations of food safety regulations, the milk container needs to be cleaned every day, which can not exceed 48 hours at most, so that the vicinity of the cafeteria site needs to be provided with cleaning and sterilizing facilities which are often provided in the kitchen of a restaurant to meet the requirements of the regulations, which leads to an increase in production cost, and sometimes the cafeteria itself and the vicinity thereof cannot be provided with the cleaning and sterilizing facilities.
