BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a device for peeling asparagus and similar elongated vegetables, including a passage for passing the vegetable through and arranged in the region of the passage at least one peeling blade which acts upon the periphery of the vegetable and presses flexibly against the vegetable, wherein the cutting edge (19) of the peeling blade is preceded in the peeling direction (23) by at least one feeler (20, 20') which lies against the periphery of the vegetable to be peeled and is connected substantially rigidly to the peeling blade, wherein each peeling blade is held on, and is capable of swivelling relative to, a blade arm mounted so as to be capable of swinging out crosswise to the longitudinal direction of the passage against a restoring force and each peeling blade has a cross section in the shape of a circle segment.
BACKGROUND OF THE INVENTION
Manually peeling asparagus, for example, is laborious and time-coasting, because every single stick has to be peeled in several stages, each stage removing only a strip of the outside skin of the asparagus. After one strip has been removed, the asparagus has to be turned through a certain angle about its longitudinal axis relative to the peeler, so that the next strip can be peeled. If the angle selected is too large, an unpeeled area is left between the two strips.
That strip then has to be peeled off separately in an extra step. Since, however, the peeled portion of the outer skin of the asparagus is difficult to distinguish from the unpeeled portion, the person peeling the asparagus may fail to notice that it has been turned through too large an angle and therefore not all the skin is removed. There is this risk particularly if relatively large quantities of asparagus are to be peeled and after some time the person doing so becomes inattentive or careless due to the work being monotonous and offering little in the way of relief.
It is also difficult for persons inexperienced in peeling to keep the depth of cut constant. In this case islands of unremoved skin may be formed between the individual peeled strips. To avoid this, the tendency is usually to select a greater depth of cut and/or a smaller angle of turn, resulting in the removal of an unnecessarily large amount of material.
The uneven depth of cut can be largely precluded by using already known implements having a swivel-mounted blade with a cutting edge arranged in a slit. However these implements represent only a minor improvement, because the asparagus still has to be peeled in a tedious working process involving several stages.
Since the relatively thin asparagus is difficult to grasp during peeling and since the sharp blade has to be moved very closely past the hand holding the asparagus, there is considerable risk of injury when peeling asparagus manually.
Therefore a peeling device of the kind mentioned at the outset has been provided which has a passage through which the vegetable to be peeled can be passed by means of a feeding device (cf. DE-U-78 16 311). Several peeling blades are provided in the region of the passage, these being arranged in pairs on mutually opposed sides of the passage and acting upon the periphery of the vegetable. The peeling blades of the known device are held on and are capable of swivelling relative to the blade arm. The blade arms for their part are mounted so as to be capable of swinging out crosswise to the longitudinal direction of the passage against a restoring force. During the peeling operation, the peeling blades of circle segment shape in cross section flexibly press against the vegetable to be peeled. As this vegetable is advanced, the straight cutting edges of the blades pare the outer skin or layer in strips.
By means of the blade arms mounted so as to be capable of swinging out against a restoring force and by means of the peeling blades capable of swivelling relative to the blade arms, the known device enables such vegetables to be peeled as are non-uniform in cross section over their length. However, even whe
