Zerno Z1 ワイドスチールホッパー + シリコンベローズコンボ

Wide funnel makes loading the beans easier. With the zerno requiring a bit more RDT in order to prevent grounds from sticking everywhere on the chute, the moist beans tend to get bottlenecked at the feed port of the grinder. No fault of the funnel, but the design of the funnel.

For the bellows, it works, but not the way I thought. It does push a bunch of grinds out, but there must be some dead zones that the air doesn't seem to reach. I still use a bulb blower for a quick burst on each side of the auger angled a bit more towards the rear and always hear some unfed stuff that the auger doesn't seem to feed into the burrs grind, then I follow by a couple taps of the bellows to push out any retained grinds. Seems like the bellows will clear the grounds, but not able to move some of the unfed bean fragments under the auger.

My current workflow is feed beans, wait till the grinding sounds stop and just whirr of spinning burrs, take off bellows to inspect grind chamber, if there are any larger beans stuck to the wall with the slow feed auger just slipping on it against the wall, I use a bamboo chopstick to move it towards the auger groove so it gets ground up, once all visible beans are ground, I will burst each side of the grind chamber and then 2-3 taps of the bellows after to clear out grinds.

If it would move the unfed fragments within the grind chamber so that i would not need to use the bulb blower, I would give it full 5 stars as that would be essentially the perfect solution to the Z1's weaknesses. It certainly helps, but not the one-off solution. Still a great product nonetheless

I found out about this company through a YouTube comment, and I'm thankful that I did. The wider hopper and bellows are a welcomed addition to my coffee workflow—no more tapping the hopper with my palm to get the last bit of grinds out. Looks & functions great

I use my kalita wave to rdt and shake the beans before loading into the zerno and this makes pouring the beans way easier.

Looks good, does exactly what it's supposed to do.
