There is a lot of shopping. How long does it take to sort 1000 pieces?

It takes about 3 hours, so it is very efficient to buy more vegetables and classify them.

Because they introduced fully automatic machines instead of manual sorting. When the truck carrying vegetables arrives at the door of Duoduo grocery store, the vegetables are taken off the truck by the manipulator, and the fresh vegetables are transported by the conveyor belt to the sorting machine, which automatically sorts vegetables according to their size and quality. The speed is three times that of manual work.
