During crushing of groundnuts at least part of the shells are retained in the ghani so as to ensure formation of a granular and compact cake. At the point of maximum contact, the pressure in a ghani is about 10 kg/cm 2 (Gujarathi, 1982), about one-third of that in a small screw-press and about one-tenth to one-hundredth of that in a large modern expeller.
