SEED AND GRAIN DRYER Russian patent published in 2019 - IPC F26B9/06 F26B25/22 

FIELD: agriculture; machine building.

SUBSTANCE: dryer relates to agricultural machine building, in particular, to machines for grain drying. Drier comprises drying agent generator, drying chamber formed by inner and outer gas-permeable bodies and end walls, said generator is communicated via gas diffuser with inner chamber body end and chamber loading and unloading means. Additionally, introduced gate between gas line and diffuser, additional drying agent supply line is introduced, consisting of series-connected gas line, gate, diffuser, connecting generator with other end of inner housing of drying chamber, humidity sensors are installed near ends of drying chamber and connected to humidity meters, outputs of which are connected to corresponding inputs of digital comparator, Outputs of inequalities of which are connected to R, S inputs of R, S flip-flop, direct and inverse outputs of which are connected through switches with control inputs of corresponding gates.

EFFECT: invention improves quality of drying, reduces power consumption for drying seeds and grains.
