PURPOSE:To obtain tasty coffee of a fixed quality at all times, by arranging a plurality of blades on the upper surface of the upper section of a basket, an approximately disc-formed rotary plate with a wall erected on the full periphery and provided eccentrically with a hot water inlet, and a spray outlet with one end communicated with a water feeder and with the other end opened near the blades on the rotary plate. CONSTITUTION:By a pump 42, water in a water tank 4 is fed to a heating pipe 3, and is turned into hot water, and hot water discharged from a spray outlet 41 via a riser 17 is orthogonally butted to the blades 32 of a rotary plate 31, to push them. Then, the rotary plate 31 is slightly rotated. By repeating this working, the rotary plate 31 is rotated in one direction. In the meantime, after the blades 32 are pushed by the hot water discharged from the spray outlet 41, the hot water is stored on the rotary plate 31 by a wall 33 set on the full periphery. Then, the hot water dripping from a hot water inlet 36 set eccentrically on the rotary plate 31 is continuously rotated, and at the same time, the hot water is uniformly dripped on pulverulent coffee 24 in a basket 45. |
