At present, pesticide residues in vegetables and fruits, preservatives, fruit wax and other widely used now, fruit and vegetable cleaning machine has become an indispensable cleaning tool for modern families. Generally speaking, the fruit and vegetable cleaning machine is used to clean 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 can not be washed off by tap water.
At present, the vegetables and fruits machine on the market is divided into ultrasonic fruit and vegetable cleaning machine, active oxygen fruit and vegetable cleaning machine, ultrasonic and active oxygen combined fruit and vegetable cleaning machine. Here are the differences between the three machines
Ultrasonic fruit and vegetable cleaning machine: 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 impurities on the surface of melon peel. However, the defects of ultrasonic fruit and vegetable cleaning machine are more prominent, and the actual effect is poor for the strong adhesion of pesticides, wax, heavy metals, etc.
Active oxygen fruit and vegetable cleaning machine: 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 the only preservative that can be allowed to directly contact with food in European countries. Therefore, the function of aerobic vegetable and fruit machine is the highest.
Ultrasonic and active oxygen fruit and vegetable cleaning machine: the advantages are comprehensive function, strong automation, liberation of people's hands, the disadvantages are high price, large area, because no human participation, working time is more than 15-20 minutes, a considerable part of the fruit and vegetable cleaning machine in order to play a clean effect, will add washing powder, food is also facing the problem of secondary pollution.
