    A little bit of chaff generally isn’t an issue in espresso as it is virtually tasteless and doesn’t usually affect extraction unless there’s an excessive amount. It can be a problem in filter brews that use a pour over brew technique- so V60 style manual brewing and drip filter machines as it can really slow down the path of the water and lead to uneven extraction.

    Neat Job And I wondered what was the point of a 3D printer?

    I use a bucket that I put some wire mesh in. I 3D printed a manifold to attach a shopvac to the bottom of it which acts to pull cool air through the beans as well as remove the chaff. I find that a red bucket works best. My blue one broke.

    As a side note, I've made a "tea" just using chaff. It wasn't good, very grassy and thin which is why I try and remove it as much as possible within my level of laziness. I know someone who looked into using it as part of horse feed but discovered it is actually quite high in caffeine. So if you want to up your jitters....

    I agree and adhere to both these comments. Remember to K.I.S.S

    During cooling I have used natural breeze as the beans cascade from one container to another to remove any remaining charf after using a popper to roast.

    My cooler is a modded 60 litre metal drum with the usual exhaust fan mounted to draw the air down and through the beans which sit in a coarse mesh sieve which allows most of the chaff to pass through it (along with the odd smaller/broken bean). Below this is a finer sieve that catches those errant beans and the vast majority of the chaff that is left over from roasting. In the end I’m guessing 98/99% is removed...... I have to vacuum out the KKTO and sweep out the shed after each roast/session.....

    One thing I find useful with that colander is the handles that make it easy to shake. Also you can pick up no name versions really cheap if you do not have one in the kitchen..

    Barry I get your point.

    I used a hottop and that exact colander for years... I’d shake the beans in it in front of a fan which would blow the chaff away. I wasn’t overlay pedantic though.

    Sure. Was suggesting that the fan helps to blow the chaff away (not so much to cool the beans if they're already cool). Particularly if you pick up the beans and drop them back into the collander thingy.

    Yes that would cool them down but the Hottop dump 'tray' with a fan underneath has already done that. I am a newby to roasting but thought it would be a good idea to remove any last bit of chaff so it does not dilute the grinds post grinder. Believe most of the chaff is removed into the chaff tray with a bit more in the roasting chamber with the hottop.

    Then I remembered we had a rectangular in sink one stored away that the wife does not like much Much like this one from "House"

    Anyway works well in that I no longer lose beans. Just a bit worried the mesh may be too fine and allowing too much chaff retention.
