14 cup food processor, uk equivalent?

[FreakinScaryCaaw]

I've found a recipe for sweet potato tortilla chips. The recipe says use a 14 cup food processor. I imagine this is fairly big?
Perhaps I should halve the recipe and buy a smaller one? At the moment I have a nutri bullet and hand blender.
Advice appreciated.

1 cup is around 24ml, so a 14 cup processor is going to be around 3.5 litres, or just under.

Thank you
