发明名称 Double piston coffee brewing machine - has two rotors swinging pistons into line with filling, brewing and discharge stations
摘要 The coffee making machine with two brewing positions has a flat plate (2) with two side by side sieves (22) one long side and has two rotors (3, 4) which can be operated so that a brewing piston (6) can be swung into line with a sieve. On a centre line parallel to this side are located two ejection positions (23, 25) for coffee grounds. The two rotors are swung about respective vertical axes (31, 41) so that few brewing chambers (32, 42) can be swung alternately into line with a sieve, and with a coffee powder filling station supported overhead. ADVANTAGE - Compact design, fast action.
