Plans for an adjustable grapes to apples size crusher?

[Rice_Guy]

Has anyone come across a design for a tool which can crush grapes as well as mush up apple? Any commercial tool which can do small volumes?

My old vintage grape crusher has smooth lobes on the rollers which is probably more gentle on grapes, but wouldn't be able to handle apples. This one here has spiked rollers and claims to be able to handle grapes and apples.

Looking at the chapter in The New Cider Makers Handbook, one direction cider folks go is a small 2mm tooth that eats away on a 2 to 3 inch object, ,,, versus working a 10 to 20mm size grape. A guess is that the bite can be compatible but shape of the hopper or adjustment of roller would be the issue.

the problem s to be effective apple need to be crushed to a pomace consistence which if used on grapes would end up a puree if lucky . the answer is they are not compatible.

Today was harvesting crab apples. The berry size for this variety is about 5/8 inch and I am again scratching my head on an efficient way to crush 5 gallon pails of grape sized apple.
IDEAS anyone?

@salcoco I would hope that a 1/8 inch stainless lip on a wheel would be able to make a quarter inch flake of apple. And the center pulpy material in grape is fluid enough that it would basically flow through a thin gap after cracking the skin.
