2. Description of the Related Art Conventionally, vegetables having leaves, such as leek and leek, are adjusted after shipping after harvesting. Since the outer leaves of the harvested vegetables are withered, insect-eating, or bent, the operation of removing these leaves and leaving only the clean leaves is performed. This operation is called an adjustment operation. FIG. 5 shows an example of the adjustment work before and after adjustment of the green onion. FIG.
As shown in (a), the outer leaves D that have been twisted or withered are removed before adjustment, and after adjustment, only the clean inner leaves U are left as shown in FIG. 5 (b). Work has been done to Conventionally, this work is performed by manually applying air or water nozzles to the root of one or several leek and blowing air or water to blow off the joint at the root of the leaf to be removed and remove the stem. The leeks were erected vertically with their leaf parts down, and the leaves remaining at the base were dropped and removed. Align the roots of the adjusted leek one by one,
They were aligned and boxed.
