The present invention relates to a hollowing machine for vegetables and fruits comprising a frame (1) with a lower table (2), a central table (3), an upper table (4) and outermost a step-by-step pivoting table (7), placed above the upper table. The pivoting table is provided with recesses or pockets for keeping a vegetable or fruit, e.g. a head of cauliflower. The machine comprises a supporting device (103) and a holding device (104) for centering and holding the head of cauliflower in the correct position. Below the outer pivoting table (7) and the upper table (4), centered under one of the recesses, a device of the iris diaphragm (83) type is arranged and straight under this diaphragm a knife head (46) and control devices (107, 36) for controlling the up- and downward movements of the knife head are arranged. The knife head comprises i.a. a cutting knife (50), which when the iris diaphragm opens is brought up through the opening of the iris diaphragm and cuts out a part of the vegetable or fruit which rests on the iris diaphragm. The knife head, the knife and the iris diaphragm are synchronized with the step-by-step pivoting table and depends on and is controlled by the diameter of the head of cauliflower. When the knife has cut out the part in question of the vegetable or fruit the knife is immediately withdrawn at the same time as the cut out part falls down through the opening of the iris diaphragm and out to a collecting unit. The remaining part of the vegetable or fruit may thereafter be transported to a separate collecting unit. |
