Document Type and Number:
WIPO Patent Application WO/2019/144363
Kind Code:
A1
Abstract:
A method of impact coffee tamping based on a constant pressure, comprising the following steps: (1) starting tamping, places a tamping cradle on the coffee powder to be tamped and pressing down an operating handle, and stores the pressure into an energy storage mechanism; (2) after pressing down to a preset position, the energy storage mechanism relieves the pressure and releases the same to the tamping cradle by triggering an impact transmission mechanism, achieving the impact tamping operation; (3) after the tamping is finished, raises the operating handle to stop pressing down and triggers the impact transmission mechanism and the energy storage mechanism to automatically return back for preparing for the next tamping operation. The method achieves tamping with a constant impact pressure, has the effect of increased pressure and reduced labor.
