Description

Chopping block special for beans

Technical Field

The invention relates to the technical field of chopping boards, in particular to a chopping board special for beans.

Background

The chopping board is a Chinese vocabulary, refers to an appliance which is padded under the chopping board when a user beats, cuts, chops and smashes things, and is generally used for cooking; plastic chopping boards, wooden chopping boards, bamboo chopping boards, toughened glass chopping boards and the like; respectively weighing chopping boards, chopping boards and chopping boards; the wooden chopping board has high density, strong toughness and firm use, but the wooden chopping board is not easy to select due to a plurality of types of wooden chopping boards, and some wooden chopping boards (such as ebony) contain toxic substances and have peculiar smell, so dishes can be polluted when the wooden chopping board is used for chopping vegetables, and symptoms of vomiting, abdominal pain and dizziness can be easily caused. Some chopping boards with loose wood, such as poplar chopping boards, have insufficient hardness and are easy to crack, knife marks are easy to generate on the surfaces of the chopping boards, and if the chopping boards are not completely cleaned, dirt and dirt are easy to store, bacteria are bred, and food is polluted.

The existing chopping block special for the green beans is a single plate, and the green beans are round in shape, and a mechanism for protecting the green beans is not arranged on the surface of the chopping block, so that the cut green beans easily roll on the chopping block when the green beans are cut, and the green beans fall off; and do not set up on the present chopping block and carry out filterable mechanism to water, the easy moisture loss to the desktop on the chopping block is placed to the beans that just washed bundle, causes the desktop to pollute, and present chopping block is only a plank, is difficult to highly adjust the chopping block, and different crowds are difficult to adjust by oneself at the service area comfort level of difference.
