At present, vegetable and fruit pesticide residues, preservatives, fruit wax and other widely used now, vegetable cutter has become an indispensable cleaning tool for modern families. Generally speaking, the vegetable cutter is used to clean up fresh fruits and vegetables, but it is not only to clean up the dirt on vegetables, but also to clean up the pesticide residues and bacteria residues of vegetables and fruits that cannot be washed off by tap water.

目前市面上的蔬菜水果机分为超声波切菜机、活氧切菜机、超声波和活氧结合切菜机。下面来介绍这三款蔬菜自动切菜机的差别：

At present, the vegetables and fruits machine on the market is divided into ultrasonic cutting machine, active oxygen cutting machine, ultrasonic and active oxygen combined cutting machine. Here are the differences between the three types of automatic vegetable cutters

超声波切菜机：关键运用超声波的高频率振动、造成很多细微气泡，利用气泡变大合闭产生负压力，来除去瓜果皮表层的污渍、杂物，可是超声波切菜机的缺陷比较突出，针对附着性强的农药、蜡质、重金属等实际效果差。

Ultrasonic chopper: the key is to use the high frequency vibration of ultrasonic to cause many tiny bubbles, and use the bubbles to become larger and close to produce negative pressure to remove the stains and debris on the surface of melon peel. However, the defects of ultrasonic chopper are more prominent, and the actual effect is poor for the strong adhesion of pesticides, wax, heavy metals, etc.
                          

活氧切菜机：主要是运用活氧具有的、去农药残留作用来保持新鲜水果的、去农药残留目地。很多人对活氧不了解，实际上活氧一直在人们生活中，雷电后、空气清新是因为闪电气体释放出来很多臭氧;森林密度高的自然环境中，活氧浓度也会高。迄今为止，活氧是欧洲能够 准许直接接触食品类的防腐剂。因此，活氧蔬菜水果机的作用是非常高的的。

Active oxygen vegetable cutter: it mainly uses the natural function of active oxygen to disinfect and remove pesticide residues to maintain the disinfection and sterilization of fresh fruits and remove pesticide residues. Many people don't know about active oxygen. In fact, active oxygen has always been in people's lives. After lightning, the air is fresh because the lightning gas releases a lot of ozone. In the natural environment with high forest density, the concentration of active oxygen will also be high. So far, active oxygen is a preservative that allows direct contact with food in Europe. Therefore, the function of the aerobic vegetable and fruit machine is very high.

超声波和活氧切菜机：优点是功能全 面、自动化强、解放人的双手，缺点是高昂，占地面积较大，因为不用人手参与、工作时间在15-20分钟以上，相当部分的切菜机为了起到洁净实际效果、会添加洗涤粉，食物同样面临二次污染的问题。

Ultrasonic and active oxygen vegetable cutter: the advantages are comprehensive function, strong automation and freeing people's hands. The disadvantages are high price and large area, because there is no need for human participation and the working time is more than 15-20 minutes. In order to achieve the actual effect of cleaning, a considerable number of vegetable cutters will add washing powder, and the food will also face the problem of secondary pollution.
