Description

Technical Field

[0001] The present invention relates to the technical field of food processing machinery, and particularly to a green vegetable head peeling and tendon-removing device. Background Art

[0002] Pickled mustard is mainly made from green vegetable heads, which are picked from February to May every year. During the growth process, the green vegetable heads will form coarse fibers, that is, old tendons. After picking, the fresh vegetable heads need to be pickled to remove salt and dehydrated, and then manually peeled and tendon-removed. Among them, peeling and tendon-removing have become a difficult point for pickled mustard factories. At present, this technology in China is still in a bottleneck state, and it has always been impossible to achieve the peeling and tendon-removing process through mechanical automation. Pickled mustard factories can only use a large number of manual workers. Because the sizes and shapes of the vegetable heads are different, and after pickling, the epidermis is very soft, and the positions of the old tendons on the outside of the pickled mustard are different. Due to the lack of automated machinery, relying solely on manual peeling and tendon-removing has low efficiency, high labor costs, and it is always difficult to completely remove the old tendons manually. At the same time, it will also affect the taste and quality of pickled mustard products. Summary of the Invention
