Cross-sectional drawing of the flesh and skin
This increases the number of over-
lapping passes of the blade, there-
by increasing the amount of skin
removal. The result is a smoothly
peeled surface.
Increasing the number
Cross-sectional drawing of the flesh and skin
Flesh

Skin
This decreases the number of over-
lapping passes of the blade, thus
taking off less skin. The surface of
the fruit will therefore have more re-
sidual skin and angles, but the yield
of fruit will be greater.
