However, it is cumbersome to clean one by one.

On the other hand, when washing relatively small sized fruits such as grapes, jujube, cherry, etc., as described above, if you wash one by one, since the fruits are small in volume and high in quantity, they are not only very time-consuming to wash. It is also difficult to clean every single fruit thoroughly.

Thus, most people would normally think that putting such small fruit in a container at once, pouring clean water, stirring it by hand, then pouring water and completing the wash, and that such washing is enough, Of course, no washing can be done, as well as fungal bacteria caused by breakage of residual pesticides or epidermis of the fruit.

In addition, if you wash foods that must be cleaned before eating or cooking, such as mushrooms, tomatoes, shellfish, or shrimp, you cannot clean them in the manner described above, so you must wash them one by one, thus requiring too much time. There is a problem that is exhausted. This is a problem that exists at home or in the kitchen of a restaurant, which cookers have long wanted to solve.

The object of the present invention is to design and provide a device that can easily and quickly and safely wash various foods as described above, and also to enable cookers to wash food completely using such devices. .
