I have the KitchenAid FVSP some time. I use to make "fruit jelly" when I want juice elder berries or blackberries. This is also quite good if you're not too much "pushing". By Kegelsieb comes only Mus and juice and the kernels and shells come as more or less dry "sausage" out. If it were not merely the ever-consuming and long cleaning after the juices. This somehow makes the screw until the "middle of the hopper," are seeds and other odds and ends in a "druchgehendes hole" pressed into the screw-Mitte, where the funnel of the drive square's inside. The "hole" runs until the front end of the worm. How exactly pure reach the nuclei and remains in that hole, is not quite clear. The fact is that every time I juiced berries, this ca.1..2mm thin hole is completely clogged with seeds. This hole again must be cleaned of all you would druchstoßen with a sturdy wire. That's always a Sauerrei. Maybe I do something wrong or is this a "faulty design".
