Tomsk has found a way to increase the collection of useful products to 40 percent
A drone that can knock down cedar cones with a stream of air is being developed by scientists at Tomsk State University. Thanks to the invention, they will help industrialists produce 40 percent more useful product.
As reported at TSU, wild plants are still collected mainly by hand — cones are shaken off tall cedar trees, stuffed into bags, and only then taken to a processing factory. To collect more, harvesters, for example, in the Ongudai and Ust-Kansky districts of the Altai Territory are waiting for windy weather. After strong gusts of wind, the cones fall to the ground in large quantities, and without them, the harvest is only 5-10 percent of the average seasonal harvest.
The essence of the scientists’ development is simple — a special device will produce a stream of air right near the crown of the tree, blowing the cones out of there. The main advantage of technology (after economic benefits) is the absence of harm to nature. It will increase the harvest by up to 40 percent.
Altai companies collecting pine cones note that in addition to improving the technology for collecting them, they plan to create a large-scale production of pine nut kernels in Siberia. Until now, raw materials are taken to China and sold from there all over the world.
In addition to blowing cones from trees, TSU is developing technologies for quick and convenient collection from the ground, as well as transportation using exoskeletons.
