After the success of the DF64 declumper and chute modification, it is finally time for the DF83. Lance Hedrick did a great review on this phenomenal grinder mentioning its only issue - the declumper.
I have put all my experience and engineering skillset into developing this chute and declumper for the DF83. The goal was to reduce the regrinding which is caused by the double stock declumpers and to prevent clogging at high flow rates.
In order to tackle this challenge, two parts are needed.
1. On the one hand, the upgraded declumper which was inspired by the Mythos declumper and is cut out of a PET foil. It removes big clumps, static and the big open cross section area means low resistance and therefore lower retention.
2. The improved chute reduces dead space and removes channel corners by transitioning from a rectangular shape to a round one. This way fine coffee grounds are prevented from accumulating after the declumper and in the chute itself.
Additionally, the opening of the improved chute is larger compared to the stock chute leading to lower probability of clogging.
The angle of the declumper flaps can be manually adjusted to balance static and retention.
Depending on the humidity level of your location one spritz of RDT might be needed.
Installation: In order to install the declumper, the DF83 need to be partially opened. After the stock declumper and chute are removed, the same screws can be used to install the upgraded declumper and chute.

I bought this because I broke my original chute (which is a design flaw of the DF83 itself)
It's hard for me to tell if it's a significantly better, as I still find time I can lose up to .8 grams on an espresso grind.
Also, I have to regularly clean it out as eventually the machine starts choking. To me this feels like the chute might be designed the best it can, but ultimately, coffee can't help buy get stuck in the chute and eventually stops coffee from passing through.
A last thing, which may again be more a flaw of the grinder itself and not the chute, is it's still impossible to pull off the front plate without breaking the chute in the process. I have found no way, no matter how gentle, to coax the damn thing off without breaking the chute.
I dealt with the site excellent and the pieces are excellent
Material hat noch Luft nach oben, musste leider schon geklebt werden
Endlich keine Probleme mehr mit der DF83
