Using a garden shredder as an apple scratter

No Whole apples go in, a sort of slurry comes out

Unless you get into it, and do it there is n reason why you would

I think so.

Incidentally the apple *presses* do not produce particularly cloudy liquid. Apple juice left to its own devices or given a helping hand turns into scrumpy, and if left still further into cider vinegar of excellent quality. Pear juice is excellent too, but is one of natures most powerful laxatives in quantity.

Most stone-fruit pips, including peaches, nectarines, almonds, apricots, pears and apples contain cyanide. With the first four, it's in the kernel, not immediately accessible unless you break open the pit.

Cyanide tastes of almonds because that's what's in the almond kernel. Some varieties of almond contain more cyanide than others; bitter almonds contain more than sweet almonds, for example. To ingest a lethal dose of apple pips you'd have to consume something like half to one cup of pips in one go. That's equivalent to an awful lot of cider. I think you'd be flat on the floor long before you drank anywhere enough to kill you!

In general only blenders will smash pips. a pulp mill wont and neither will a press.
