Someone sorry I have forgotten whom mentioned the inconsistency of the Sunbeam EMO450/480 grinders when used near empty to grind for a single cup say 15g. lots.
This is probably not a characteristic unique to the Sunbeam grinders, however that’s my context.
Thank you for drawing my attention to this observation as I had not heard of or considered that inconsistency from this source may be significant.
The grinder is the most expensive item in my coffee inventory and since this is how I have been using my Sunbeam EM0450 I had a think.
I thought perhaps a hopper with smaller cross sectional area and/or a dummy bean mass load may, be effective at reducing the inconsistency.
Below is my suggested tool to investigate the source of this observed inconsistency.
I plan to evaluate samples ground using the original hopper and the mini hopper and dummy and attempt to compare grind size profiles between methods.
If any one is interested in what material were used:
“The Mini Hopper” is from an Ozito 12Volt 8Watt fluorescent trouble light (from Bunnings $7).
“The Dummy” itself could be made from any lightweight materials at hand.
The V1 is made from:
- an ordinary cork although one from a bottle of Grange may be better.
- a bamboo chopstick.
- a recycled disposable plastic lab tube with cap (Falcon tube)
The only tools I used were:
The bread knife to cut the plastic tube to length, pocket knife to cut the cap and the white lid and scissors to put two cuts in the plastic tube to enable it to collapse enough to fit into the grinder’s hopper base and throat of the upper bur holder.
A drill and bit, for the cork, tube and cap.
The “Dummy” should be as light as the load you would want to put on the burs (?15g.) and may be weighted if more weight is desired, the position of the tube and cap should be adjusted so the bottom of the “Dummy” does not come in contact with the rotating grinder parts.
Kind Regards
