By the way, in this conventional automatic bamboo shoot peeling apparatus, the diameter of the two rollers is the same, so that when the bamboo shoot skin is caught in the rollers, the skin is forced. The peeling is performed in a state where the bamboo shoot is torn, and there is a problem that the bamboo shoot is easily broken during the peeling operation. Also, since the outer circumference of the two rollers is smooth,
Sliding occurs between the roller and the skin, resulting in poor skin peeling efficiency.Furthermore, since the peel and the skin easily adhere to the roller, it is difficult for the bamboo shoot skin to be caught in the roller when used continuously. There is also a disadvantage. Furthermore, since the rollers are arranged horizontally, the peeled bamboo shoots are not automatically discharged, so it takes time and effort to remove the bamboo shoots from the peeling machine, and the finger is caught in the rollers. There is also the problem of danger. In view of these problems, the absence of a request for examination, and the number of years that have passed since publication, it is thought that this idea has not been completed yet and has not yet been brought to practical use. The present invention has been made in view of such a problem, and reduces the ratio of bamboo shoots to be broken during the peeling operation, and increases the frictional force between the roller and the leather, so that the skin is less efficient. It is an object of the present invention to provide a bamboo shoot peeling apparatus that enables peeling, and enables smooth and safe continuous peeling work.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to two rubber driving and driven rollers each having a different diameter and a spiral groove formed on the outer periphery. Are arranged in contact with each other up and down, and the two rollers have an electric or manual mechanism in which both of them rotate inward in conjunction with gears. Further, the present invention makes the diameters of the two rollers different from each other, and
By spirally forming one groove on the outer periphery of the book roller, the bamboo shoots are rolled up when the bamboo shoots are caught in the rollers, and the skin is peeled off while rotating. It is what it was. As a result, the skin is smoothly peeled off in such a manner that the skin wound tightly around the bamboo shoot is unwound, and the bamboo shoot is hard to break. Further, by applying a single groove spirally on the outer periphery of the two rollers, the frictional force between the two rollers and the bamboo shoot skin increases, and slippage decreases.
At the same time as the efficiency of the peeling is improved, an effect is obtained that the skin of the bamboo shoots and the flakes are less likely to adhere to the rollers.
