The invention relates to installations for drying and processing grain in agriculture, and can also be used in construction, chemical, and other sectors of the national economy.

The purpose of the invention is to improve the quality and efficiency of drying and grain processing.

Fig 1 shows the installation, general view; Fig 2 - control circuit

The plant for drying and processing grain consists of a body containing a bottom surface 1 with cascaded protrusions 2, equipped with heaters 3, and longitudinal ribs 4, an upper surface 5 with similar protrusions 6. The body rests on spring-loaded articulated supports 7, the top of which is provided the cylinder 8. The internal cavity 9 of the housing is connected to the ventilation suction tubes 10 containing the balancing elastic flaps 11, the throttles-valves 12 connected to the suction system (not shown). A sensor 13 for determining the initial humidity is installed on the charging port 14. Gates 15 are installed on the upper surface 5 of the housing, as well as infrared 16 and luminescent 17 emitters in a checkerboard pattern. The discharge pipe 18 is equipped with a balanced valve 19 and a humidity sensor 20. The installation is equipped with a control panel 21. Internal surfaces of housing 1 and 5 are made of reflective material. The unit is equipped with a vibration exciter 22.

Installation for drying and grain processing works as follows.

The grain under the action of its own weight and vibrations through the loading nozzle 14 moves into the installation body, the initial humidity is measured by means of the sensor 13, and dust is removed through the ventilation suction 10, after which the grains fall onto the cascade protrusion 2 and under action in staggered order infrared 16 and luminescent 17 emitters. The discharge nozzle 18 is equipped with a balanced valve 19 and a humidity sensor 20. At the same time, the installation is equipped with a control panel 21. The inner surfaces 1 and 5 of the housing are made of reflective material. The installation is equipped with a vibration exciter 22. 2C.p. f-ly, 2 ill.

By vibrating from the vibration exciter 22, they are poured downward, and the grains are gradually heated from the effect of heaters 3 through the surface and the longitudinal ribs 4 in the vibrocummer layer and the rarefied air flow during its processing by radiant energy from infrared 16 and luminescent 17 emitters. The amount of heating, speed of movement, rarefaction, speed of air flow and infrared and luminescent irradiation are provided through the control panel 21 of the control of the angle of inclination of the body by the power cylinder 8, the difference

the temperature of the heaters 3, the magnitude of the extension of the gates 15 and the magnitude of the vacuum created by the aspiration system. The process of drying and grain processing is automated.

Technical and economic efficiency

the application of the proposed plant for drying and cleaning the grain in comparison with the known ones is to improve the quality achieved by optimal drying and processing in a vibro-drip layer, thin

air flow, temperature environment, infrared and luminescent rays, which allows to obtain dry and enriched grains, as well as to increase efficiency by increasing productivity in

5-6 times, reducing material consumption and energy consumption by 30-40%.
