Description

  The present invention relates to a method and apparatus for removing stem cores from headed vegetables such as Chinese cabbage and lettuce.

  Since the leaves of the headed vegetables form leaf balls and the base ends of the leaves are connected to the stem core, as a pretreatment for cooking, first the core is removed, and the leaf ball leaves must be peeled off one by one and separated Don't be. In order to remove the core, there has been proposed an apparatus (Patent Document 1) in which a cut is made by removing from the bottom of the vegetable (Patent Document 1), or a mechanical tool by scraping with a rotary cutter. However, the leaf ball after the removal of the core must be divided into two or four parts, or the leaves must be removed one by one from the leaf ball mass without being divided.

No. 7-80 Japanese Utility Model Publication No. 3-99990

The division of leaf balls and the separation of entangled leaves are done manually, but it is a laborious work, so doing this work in large quantities in the factory will cause the worker to become extremely tired and work. Efficiency is low.
When the peeled leaves are shredded, if the width of the fine pieces is too thin at the edges of the leaves, they tend to become scraps. Therefore, dividing the leaf sphere prior to leaf shredding has the disadvantage of increasing the amount of leaf waste.

  The purpose of the present invention is to cut the connection between the stem core and the leaf proximal end of the headed vegetables, and then rotate the headed vegetables to separate the leaves by centrifugal force, or to release the tangles of the leaves to facilitate peeling. It is to provide a method and apparatus.

  The invention of claim 1 inserts a cutter from the bottom of the headed vegetables to the center of the leaf ball along the periphery of the stem core, applies a cut around the stem core, and connects the stem core to the leaf base end. In this method, the head vegetables are rotated around the stem core, the connection between the core side surface and the leaf balls and the entanglement between the leaves are separated by centrifugal force, and the stem core of the head vegetables is removed.

  According to a second aspect of the present invention, in the first aspect of the invention, after the connection between the core side surface and the leaf ball and the entanglement between the leaves are separated by centrifugal force, the connection between the upper part of the stem core and the inner leaf of the leaf ball is cut. This is a method of removing the stem core of headed vegetables.

  Invention of Claim 3 thru | or 11 is an apparatus which isolate | separates the leaf of a head-bound vegetable and removes a stem core. A support stand for standing the head of vegetables and placing the bottom, a pusher that holds the top of the leaf balls placed on the support, and a vertical movement that can be moved up and down from the support base, and can be rotated at a controlled timing and speed. And a cylindrical cutter having a blade surface on the upper edge, and a lifting device and a rotating device linked to the cylindrical cutter.

The invention of claim 12 is provided with a support plate that supports the headed vegetables sideways on the support table, a support plate that contacts the bottom of the head vegetables on one side of the support table, and a cylindrical cutter that appears and rotates horizontally. Deploy a presser to hold the top of the headed vegetables on the other side of the table,
For the headed vegetables supported sideways on the support table, insert a cylindrical cutter from the side, cut the connection between the stem core and the proximal end of the leaf, and after separating the support table and the cylindrical cutter from each other, It is a device that removes the stem core, loosening the tangle of leaf balls and separating the leaves by the rotation of the cylindrical cutter.

  Since the connection between the stem core and leaf base of the headed vegetable is cut with a cylindrical cutter, the stem core is separated from the leaf ball, and the cylindrical cutter pierces the leaf ball and rotates integrally, so that the leaf is subjected to centrifugal force. It is swung away from the stem core and scatters apart. If the entanglement of the leaf is strong, the scattering of the leaf is small, but even in that case, the entanglement of the leaf is weakened, so it can be lightly unraveled by hand and the burden on the operator can be reduced. It is not necessary to divide the leaf ball, and the leaf can be separated from the stem core with a single size, so there is little generation of debris when shredding the leaf.
