Abstract
A microwave drying device for drying products in the form of grains, comprising a microwave source, at least one waveguide coupled electromagnetically to the microwave source, means for injecting into this waveguide the product to be treated, means for driving this product in the waveguide, means for causing a forced circulation of dry air in the waveguide, means for discharging the air charged with the humidity given up by the product to be treated, and means for collecting the dried product in this waveguide, wherein the waveguide is closed on itself so as to form a ring, a part of this waveguide forming a channel through which the product to be treated may pass, said channel being connected at its ends to pipes for feeding therein and removing therefrom the product, these pipes forming cut-off waveguide.
