The locking rotor apparatus consists of a body 1 with a conical bottom 2, in the central part of the body 1 there is a 3-lift pipe with a socket 4 having perforations 5. The pipe 3 of the airlift is installed in the b-guides with the possibility of vertical reciprocating movement and mutual It is equipped with a lifting mechanism 7. Inside the apparatus, a false bottom 8 is mounted, which has a conical shape and which has a tilt angle of 32-42 ° to the horizontal. A false bottom and a conical bottom 2 of the apparatus form an equalization chamber 9 with a suzhak tsims axial section. Under the false bottom 8 there are bubblers 10 having openings 11. At the top of the housing 1 of the apparatus, a collector 12 with nozzles 13 is installed to irrigate the surface during germination and 14 collectors with nozzles 15 for rinsing and washing the vertical walls of the housing 1 of the apparatus A vent-heat exchange unit 16 for blowing grain. Air from unit 16 is supplied to the rio duct 17 drawn out above the filling level of the apparatus with water. The unloading product tube 18 is provided with a valve 19, which has a driving device 20. A ha 21 connects the device 20 to the valve 19. Cleaning solutions, disinfectants, substances that stimulate and inhibit grain growth are prepared in the tank 22, which is usually installed above the apparatus . The tank 22 is equipped with a stirrer 23 and is connected to the sub-mesh space of the apparatus, pipe 24-. From the compressed air source (not shown) to the bubbler rings 10, pipelines 25 are installed, having autonomous valves, designed for remote control. Wind-heat exchange; the unit 16 is also remotely controlled from a central control panel or a software device (not shown) A pipe 26 ending with a diffuser 27 serves to supply compressed air to the airlift. A pipe 28 serves to drain the grain as it is transported by an airlift. a malt freezing box (not shown) using a pump 30. Serial breeder 31 serves to transport grain to a malt seedling box. The lock and seed apparatus for production from oloda works as follows. After pouring water and backfilling The barley is kept under water for 610 hours. At this time, it is washed, disinfected, removed the alloy, as well as by direct current of air supplied by bar boters 10 through apertures 11. To carry out the washing with an airlift, its pipe 3 rises and installs in the upper position. The PCP pipe 26 and the diffuser 27 enter compressed air into the pipe 3, which entrains the grain-water mixture and directs it back to the apparatus through the pipe 28. During this operation, the pipe 28 is previously disconnected from the grain grower 31 and turned at some angle. During operation, the pipe 3 rotates around its axis, which contributes to the uniform distribution of the airlift being transferred to the grains. The operations listed above: washing, disinfecting, removing the alloy, aeration do not differ from those conducted in the well-known lock vats. The mixing of the grain carried out in the proposed apparatus is also not substantially different from the mixing in conventional lock tanks. But in the apparatus in question before the air pause, before the water starts to drain, it removes grain from the airlift pipe, for which the latter is lowered to the lowest position by mechanism 7 until the perforated socket 4 is seated on the central cone of the false bottom 8. compressed air, through pipe 26 through the diffuser 27, the grain output to the mixture is removed from the pipe. 3 airlift, and in its place through the perforation 5 in the socket 4 comes clean water from the body of the apparatus. The same barley grain can not go through this perforation due to the small width of the cracks. After the airlift pipe has been completely freed from the barley and the apparatus is removed, water is removed, and the first air pause follows. During the air pause, it is necessary to conduct a uniform and intensive purging of the grain with air with a temperature of 14-16 ° C. During the air pause, there is an intensive grain growth. The first air pause lasts 12 hours. After the indicated time has elapsed, the grain is submerged a second time under water. In the submerged state, the grain is aerated, stirred using bubblers and airlift with moderate compressed air supply and agitated. The aeration and peremestirovaniya grain is carried out in the usual order, as this is done in a & lock vats. When germinating grains in a chiropractic apparatus, it is necessary to agitate the grain. The grain irrigation is carried out with compressed air at the end of the grain aging under water. To intensify the agitated compressed air

Serve successively into separate bubbler rings. Each of the individual rings is turned on for 1-2 minutes. The weight of the agitating cycle lasts 6-10 minutes. The height of emissions of the grain-water mixture by compressed air from the surface of the grain above the bubbler reaches 300-400 m

After the end of the agitating with the help of the bubblers 10, the agitating is carried out with the help of airlift assistance. All operations with airlift are carried out as described above, but the pressure on the supply pipe of the apparatus is increased, compared with the pressure at which the grain was mixed.

At the end of the second submersion, an air pause of 20–40 hours follows. During this air pause, the grain is intensively blown from the vent-heat exchanger unit.

After the completion of the second air pause, the grain is again immersed under the water for a third time. The duration of the aging of the grain under water is 5-6 hours.

During this submergence of the grain under water, it is briefly agitated with compressed air. Tedding is carried out in the same way as it was done during the second exposure of the grain under water, but during this turning, the inhibitor solution, KVg or CaClQ solution, as well as the lock water, go to the equalization chamber 9 through pipe 24 Taken from the second lock.

When this grain is submerged under water, its humidity is adjusted to 48-50%, the energy is re-filled, after which it is transferred to a pneumogical box.

The transfer of grain is carried out by gravity, airlift or pump. In all cases, the airlift pipe is set to the upper position.

When the grain is transferred by an airlift, the valve 19 remains closed and the pipe 28 is connected to the grain producer 31.

When the grain is transferred by gravity or by pump 30, baroters Y are put into operation. Pipe 26 and compressed air is supplied through the airlift diffuser 27 — the airlift begins to work and agitate the germinated grain. After 12 min of operation of the airlift, the valve 19 is opened with the help of the pull 21 and the driving device 20. In all cases of the transfer of grain, the level in the apparatus is kept at the initial height, i.e. 200-300 mm above the level of the grain poured into the apparatus. When the apparatus is emptied by gravity after opening the valve 19, the grain is directed to the box below the apparatus. The slope of the product tube shall not be less than

25 ° with respect to the horizontal.

When the grain is pumped into the pneumatic box by the pump 30, the pump is turned on a few seconds before the opening of the valve 19.

After the apparatus is completely emptied, it is cleaned and disinfected in the usual manner.
