Pneumatic tubes are making a comeback in industries that do a lot of sorting as well. For instance, in agriculture, they are used to automating produce distribution systems, allowing processing to happen much more quickly, and sorting fruit and other products efficiently.
An added bonus is that the tubes are sealed, cutting down on produce getting wet or spreading disease from plant to plant by keeping fruit and other products inside their respective tubes.
Pneumatic tubes for agriculture can allow packaging by weight and type, eliminating the need to hand-sort much of the product being harvested.
