Abstract
The present disclosure relates to a coffee beverage extractor of a hand-drip type, and to a simple and convenient coffee beverage extraction method and apparatus, wherein, to reduce filter clogging and shorten the extraction time, by installing an improved dripper having a stirring function applied thereto, a coffee beverage can be quickly extracted at an espresso level from finely ground coffee beans, and a coffee beverage with deep flavor and increased extraction efficiency can be brewed from compressed coffee bean blocks and different types of ground coffee beans.
Claims13
A coffee beverage brewing extraction method for extracting a coffee beverage using a hot water brewing method, the coffee beverage brewing extraction method comprising:
- maintaining a rate at which a coffee beverage is extracted from a mixed solution of coffee beans and hot water in a dripper or a filter through an extraction port of the dripper or filter holes for a certain period of time in order to expand an extraction area where the dripper or a filter surface of the filter and a mixed solution of coffee beans and hot water contact each other while coffee is being extracted to secure an extraction area where the mixed solution comes into contact with the dripper or the filter surface of the filter;
- and
- stirring the mixed solution in a state in which a level of the mixed solution is raised by a volume of a rotor disposed inside the dripper or the filter and submerged in the mixed solution to further expand the extraction area to extract the coffee beverage from the dripper or the filter.
A coffee beverage brewing extraction apparatus for extracting a coffee beverage using a hot water brewing method, the apparatus comprising:
- a dripper or a filter having an extraction port or filter holes for maintaining a rate at which a coffee beverage is extracted from a mixed solution of coffee beans and hot water in the dripper or the filter through the extraction port or the filter holes for a certain period of time in order to expand an extraction area where the dripper or a filter surface of the filter and the mixed solution of coffee beans and hot water contact each other while coffee is being extracted to secure an area where the mixed solution comes into contact with the dripper or the filter surface of the filter;
- and
- a rotor that raises a level of the mixed solution by a volume of the rotor disposed inside the dripper or the filter and submerged in the mixed solution to further expand the extraction area and stirs the mixed solution.
