Abstract
Whole raw onions, as harvested, are cleaned and scalded sufficiently to slicken the membrane interface between the outermost and next inner layers of flesh without appreciably affecting the interfaces between subsequent layers of flesh. The root and stem ends are then cut off, and the outermost layers of flesh of each onion bulb and any outer skin adherant thereto is cut longitudinally along the root-stem axis of the bulb to provide a slit therealong. The so-slit onion bulb is then gripped at opposite sides of and along the slit, and the slit outermost layer of flesh and any adherant skin are pushed downwardly and stripped from the onion bulb, followed by separation of the strippings and the remaining bulb.
Claims5
A method of peeling onions on an industrial, mass production basis, comprising cleaning the onions as harvested;
- scalding the onions sufficiently to slicken the membrane interface of each cleaned onion between the outermost layer of flesh and the next inner layer without appreciably affecting the interfaces between subsequent layers of flesh;
- mechanically cutting off root and stem ends;
- mechanically cutting through said outermost layer of flesh of each onion and any skin adherent thereto longitudinally along the root-stem axis of the onion bulb, without cutting completely through any subsequent layers of flesh, to provide a slit therealong;
- mechanically stripping said outermost layer of flesh and any skin adherent thereto from each onion bulb along the slickened interface by gripping the said outermost layer of flesh and any skin adherent thereto of the so-slit onion bulb at opposite sides of the slit and pushing downwardly against the onion;
- and separating the peeled onion bulbs and the strippings, one from the other.
