FILTER FOR COFFEE-EXTRACTION, COFFEE EXTRACTOR USING IT, AND COFFEE BAG

摘要

PROBLEM TO BE SOLVED: To provide a filter for extracting coffee that can efficiently extract coffee that is rich in taste from roasted coffee aggregate using normal tempera ture water. SOLUTION: The filter for extracting coffer that is used for extracting a roasted coffee aggregate at a room temperature is a slender inverse-conical one whose diameter is contracted downward while accommodating a roasted coffee aggregate 4 so that weight per the unit bottom area of the roasted coffee aggregate 4 becomes larger than the buoyancy of the room temperature water and forming an agitation flow for agitating the mixed liquid of the roasted coffee aggregate 4 that is accommodated in side and the room temperature water in upper and lower directions by pouring the room temperature water.
