Description

Experimental data obtained by the Crimean Plant Protection Institute showed for 3 years that when the seed grain is heated with dry hot air at a certain temperature and for some time the dusty wheat in the crops is completely absent or is observed only as traces. A necessary condition for obtaining the desired effect is uniform heating of the whole processed grain and possibly a dry heating agent.

In the attached drawing of FIG. 1 is a side view of the device; FIG. 2- its top view; FIG. 3-part section of a grain tank and an elevator; FIG. 4-side view; FIG. 5 is the same installation, but in which the source of hot gases is the locomobile.

Significant parts of the device are: a tank for grain 5 with two crowns located one above the other, an elevator 10 with buckets for the continuous circulation of grain, heating furnaces for air (or a locomobile), a fan 3 for pumping into the tank 5 hot air or flue gases and associated piping and engines.

The grain is loaded into the tank 5 through the hole 8 in its lid and enters the funnel equipped with a net 17 for free penetration of hot air and uniform heating of the grain (Fig. 3). From the aforesaid funnel, the grain enters by gravity into the underlying funnel b, equipped with a diagonal grid, through which the forced hot air passes and heats the sapant grain. From the funnel 6, the grain enters the elevator 10 through pipe 7, equipped with buckets and the heated grain continuously feeding part of it into the upper funnel until it is fully heated at a certain temperature. The necessary air is heated in electric heaters 7 and, sucked by fan 3, flows through conduit 2 into the lower chamber of funnel b, under the grid through which it enters tank 5, heats the sifting grain and removes it with pipe 4 to the fan. conduit 2 enters another electric heater 1 to reheat. In reservoir .5, an opening 15 is provided, which has the purpose to not heat the hot air through the entire layer of cold grain at the beginning, and not to risk the possibility of moisture condensation, but to release hot air outside and close the opening 15 with the lid, starting air circulation only after the grain warms up

evenly in all its parts. The purpose is provided by the tube 9, which lets in heated air from the chamber b into the elevator E. A completely heated grain is poured out through the tube 16 (Fig. 4). The electric motor L is used for the movement of the fan 3, and the electric motor / 2 for the movement of the elevator. Thermoometers and rheostats are available to set and maintain a certain temperature throughout the apparatus. The entire device is serviced by one person.

Additions and modifications of the proposed device are caused by the need to install an additional cone 7 (Fig. 5), removed from the experiments, with the aim of a more uniform distribution of the grain flowing from the upper funnel to the lower one, and by the fact that necessary to heat the air and activate the fan and the elevator. Therefore, a combination of the described device with a locomobile is proposed, the flue gases of which replace the heated air, and the steam serves, with the help of appropriate devices, to move the fan and the elevator. However, this requires some minor modifications to the locomobile. Thus, the pipe that discharges the exhaust steam must be removed from the flue pipe in order to eliminate the presence of moisture in the flue gases, which is very harmful for the thermal treatment of the grain. Throttle valve 7 is installed in the chimney.

and the hole closed by the valve 2, with the aim of being able to flue gases into the smoke pipe when the locomobile is fired, and then, upon the formation of the necessary vapor pressure, into the chamber 5, which is divided into two parts by an incomplete partition: - for mixing with cold air supplied by the valve 5, in order to obtain a certain temperature at which the flue gases are introduced into the pickling device, quite similar to that described above, but equipped with the aforementioned additional cone 7 (Fig. 5). For very large installations exceeding the power of the locomobile, it is possible to use a furnace, for example, designs and structures. Ya. M. Uvarova, used for kolkhoz grain dryers.

The subject matter of the invention.

1. A method of milling grain in a countercurrent that circulates a heated air jet through a preheater and blends a treater; intended for lifting grain to the top of the dacha.

2. In the method according to p. 1, the use of locomobile flue exhaust gases for the purpose of overheating and disinfecting grain.
