Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly to a cleaning device for root and tuber crops. Background Art

[0002] There are many types of root and tuber crops, including potatoes, sweet potatoes, taros, yams, etc. These root and tuber crops have strong adaptability during the planting process and are planted globally; moreover, these crops are rich in carbohydrates and can provide food resources.

[0003] As excellent starch-based foods, root and tuber crops can be made into various delicacies according to needs. Taking potatoes as an example, they can be made into potato chips, mashed potatoes, potato cubes, potato slices, etc. Before making the required delicacies, cleaning is an essential process.

[0004] Current cleaning equipment mainly includes two types: bubble cleaning and / or brush roller cleaning. In these two mainstream cleaning equipment, a conveying device is an essential component. However, since potatoes, sweet potatoes, taros, yams, etc. all have a certain length, using the current cleaning equipment will cause certain problems; taking potatoes as an example, during the cleaning process, since most potatoes are spindle-shaped, no matter whether roller conveying or belt conveying is used, they are always prone to a state where both ends face the two sides of the conveying device and the middle faces the moving direction of the conveying device. Currently, the bubble cleaning mainly sprays water downward for rinsing, and the rinsing range is mainly the middle part of the potato. The brush roller cleaning also acts on the middle part of the potato. This results in the difficulty of cleaning the bud eyes at both ends of the potato in place, and the bud eyes at both ends of the potato are usually deeper. Therefore, problems such as soil residue are likely to occur. Summary of the Invention
