Problems solved by technology

At present, the fruit processing device used in the field of high-voltage electrostatic fresh-keeping is relatively simple, and it is a simple non-airtight support. The safety of the device is poor, and the amount of fruit processed in a single batch cannot meet the actual demand.
At the same time, because high-voltage static electricity will generate ozone during the discharge process, the enrichment of ozone will cause certain damage to the operator's body
