304 stainless steel solid base is made of high quality 304 stainless steel without rust and resistance The impact pressing method causes strong vibration inside the coffee powder through the instant powerful impact force, breaks the local support structure, and eliminates the internal . The coffee particles are more closely fit. The high-pressure water is more evenly shared, resulting in more uniform and efficient extraction. Impact powder through a large impact force to squeeze coffee powder, compacting powder is uneven, reducing the requirements of cloth powder, easy to deal with the agglomeration problem, and solve the channel effect Horizontal pressing powder vertical filling gasket and powder bowl close fit to make the pressing powder to achieve balance horizontal pressing powder to solve the pressure deviation pressure deviation trouble to reduce channel effect After pressing to a fixed force value, the base impact and squeeze the powder again, reduce the of the powder, the channel effect, and automatically reset the powder after pressing without adjustment.
