Method for preparing hand-brewed coffee by capsule coffee machine and capsule coffee machine

Abstract

The invention relates to the technical field of food processing, in particular to equipment and a method for preparing hand-made flavor coffee. The method includes a heating stage, a primary water injection stage, a steaming stage and an extraction stage. Due to addition of the steaming stage, taste of coffee made according to the method is closer to that of hand-made coffee. Hot water is injected into a capsule to steam coffee powder, water supply is stopped for a while to allow complete contact of the hot water and the coffee powder, the coffee powder is heated to expand and release carbon dioxide at the same time, bubbled gaps are formed among the coffee powder and enable the coffee powder to form an uniform filter layer, a space required for penetration of hot water is provided, and quality of coffee extracted at the extraction stage is improved. The volume of the coffee powder is not larger than 80% of the capacity of a capsule, so that a space is reserved for coffee powder expansion and gap formation, and influences on extraction time and extraction quality due to coffee powder gap nonuniformity caused by insufficient expansion of the coffee powder in the capsule are avoided.

Description

technical field [0001] The invention relates to the technical field of beverage preparation, in particular to a method for preparing hand-brewed coffee through capsules and a capsule coffee machine for realizing the method. [0002] technical background [0003] With the improvement of people's living standards and the adjustment of eating habits, the number of coffee drinkers is increasing, and the beverage machines are becoming more and more popular. [0004] At this stage, there are some capsule machines that can use capsules to make drinks, but generally they can only make espresso or Americano coffee. To make espresso coffee capsules, the coffee powder inside is completely compacted, and the high-pressure water pump is used to make coffee. Hot water is forcibly passed through the compacted coffee powder, thereby extracting the oil and coffee components in the coffee. This production process generally involves deep roasting of coffee beans, and the pursuit of coffee taste...

[0004] At this stage, there are some capsule machines that can use capsules to make drinks, but generally they can only make espresso or Americano coffee. To make espresso coffee capsules, the coffee powder inside is completely compacted, and the high-pressure water pump is used to make coffee. Hot water is forcibly passed through the compacted coffee powder, thereby extracting the oil and coffee components in the coffee. This production process generally involves deep roasting of coffee beans, and the pursuit of coffee taste is more about the content of the coffee oil. Aroma, due to the effect of high temperature and high pressure, for different types of coffee powder, there is a tendency to obtain a uniform coffee taste, so that the characteristics of different coffees cannot be well preserved; and the coffee capsule production process for making American coffee, because of The pursuit of fast production and strong taste is also lacking in retaining the characteristic flavor of coffee itself

[0005] On this basis, in recent years, the more popular pour-over coffee (or called single-origin coffee), the process is precisely controlled by the barista and coffee equipment, which can better extract the flavor of the coffee itself, while avoiding over-extraction and There are mixed flavors, but each barista has his own opinion on the best brewing method, and the flavor will be different according to the mood of the barista at the time, actual operation and other factors, which is difficult to promote on a large scale, and at the same time, it is automated too low level
