Description

I1

The invention relates to the brewing and alcohol industry, in particular to equipment for the production of malt.

The aim of the invention is to accelerate the malting process and improve the quality of the malt.

This goal is achieved by eliminating obstacles to the supply of air and its even distribution over the entire mass of soaked and germinating grain.

The presence of the valve unloading product pipe and its location

It prevents the accumulation of grain and the apparatus of pipe 23.

the use of the unloading product tube, which makes it possible to increase the reliability of the unloading of the lock-spreading apparatus.

Figure 1 is a schematic illustration of a key-retelling apparatus for the production of malt, a general view; Fig. 2 is a section A-A in Fig. 1 (annular distribution chamber); fig.Z - node I in figure 1 (the valve of the product pipe).

The locking rotor apparatus consists of a housing 1 with a conical bottom 2. In the housing 1 a centrally located pipe 3 airlift with a perforated socket 4. The pipe 3 airlift is installed in guides 5 with the possibility of vertical reciprocating movement and is interconnected with lifting and lowering mechanism 6 A conical false bottom 7 is mounted inside the apparatus, the formation of which has an inclination angle of 32-42 to the horizontal. The false bottom 7 and the bottom 2 of the apparatus, having a conical shape, form a balancing chamber 8 with a narrowing, .1 axial section.

Bubblers 9 are located under the false 7 inside the housing 1. A collector 10 with nozzles (not shown) is installed at the top of the apparatus housing to irrigate the grain surface during the soaking. Bubblers 9 are shaped

rings i

The apparatus contains a ventilation-heat exchange unit 11 for purging grain. Air from aggregate 11 is fed through the duct 12, which is drawn out of the filling level of the apparatus, into the annular distribution chamber 13, from where through the openings — sectors 14 in the conical1 bottom 2 of the apparatus — and the balancing measure 8.

A valve 16 with a rubber seal 17 is located directly in the discharge product pipe 15. The valve 16 is connected by means of a puff 18, mounted in the guides 19 with the possibility of vertical reciprocating movement, to the drive device 20,

Solutions washing, disinfecting, stimulating and inhibiting grain growth are prepared in a tank 21 equipped with a stirrer 22, installed, as a rule, above the apparatus. Tank 2 is connected to the supporting ry space

From the source of compressed air (not shown) to the bubblers 9 summed up the pipelines 24, with Autonomous valves, designed for

remote control. The valve of the heat exchanger unit 11 is also remotely controlled from a central control panel or a software device. (Not shown).

A pipe 25 serves to supply compressed air to the airlift. A pipe 26 for feeding grain to a malt freezing box (not shown) is provided with a sliding 27 to prevent the ingress of grain

under the sieve when turning off the adjacent vats.

Pipeline 24, pipe 25, duct 12 and pipe 23 are included in the communications system of the device.

The annular distribution chamber 13 is mounted at the bottom of the housing. 1 on the outer surface of its conical bottom 2 and communicated through a series of holes - sectors 14,

performed in the latter, with equalization chamber 8.

The ventilation-heat exchange unit 11 communicates with the equalization chamber 8 through the annular distribution chamber 13. The pipeline 28 serves to unload the grain into the pneumatic box.

The key-rearing apparatus for malt production works as follows.

The filled barley is filled with water and kept under water for 6 to 10 hours. At this time, it is washed, disinfected, removed the alloy, and also aerated with a constant current of air, supplied by bubbling 9. Splash cleaning using airlift pipe 3 lift and set in the upper position. The pipe 25 compressed air into the pipe 3 for pumping the water-grain mixture. The grain is mixed. Before the air pause, before the water begins to drain, the grain is removed from the airlift pipe, for which the latter is lowered to the lowest position by mechanism 6. After landing, due to the intense supply of compressed air through pipe 25, the grain mixture is removed from the 3 airlift pipes, and in its place through the sectors 14 in the bell 4 flows clean water from the housing 1 of the apparatus. After the complete discharge of the barley pipe 3 from the apparatus, water is removed from the apparatus, and the first air pause follows.

During the air pause, the grain is purged uniformly and intensively with air at a temperature of 18 °.

At this time there is an intensive grain growth. The first air break is 12 hours.

After the specified time, the grain is immersed a second time under water for 6 to 10 hours.

In the submerged state, the grain is aerated, mixed with the help of bubblers 9 and pipes 3 of airlift with moderate compressed air supply and agitated.

When germinating grains in a locking device, there is a need for agitating the grain. Tedding of the grain is carried out with compressed air at the end of the grain delivery under water. To intensify the agitation, compressed air is fed successively into separate bubblers 9. Each of them is turned on for 1 - 2 minutes. The whole cycle of agitating lasts from 6-10 minutes.

After termination of the agitating using bubblers 9, agitating is carried out with mixing using an airlift pipe 3.

At the end of the second submersion, an air pause of 15–30 hours follows. During this air pause, the grain is intensively purged with the aid of a ventilation-heat exchanger unit 11. 5 After the completion of the second air pause, the grain is again submerged under water. The duration of the aging of the grain under water 3 - 5 hours

During the third grain immersion

0 under water, it is briefly tedged with compressed air in the same way as during the second, but during this turning from the tank 21 into the sub-sieve space the pipe 23 is filled with inhibitor solution, KVg or CaC solution, as well as skimmed water taken from the second lock.

When this grain is submerged under water, its humidity is adjusted to 48-50%, but it is refilled and then transferred to the pneumatic box, located below the lock-ripper apparatus, by gravity flow. To do this, open the valve 16 by means of the gi 18 and

5 of the actuating device 19, the reciprocating movement of the valve 16, which prevents the unloading product pipe 15 from clogging with the germinated grain.

0 After the device is completely emptied, it is cleaned and disinfected.

The malting machine for malt production shortens the malting cycle by I5-20% and improves malt quality.

The application of the invention accelerates the malting process.

and improving malt quality as a result of uniform air distribution throughout the soaked and germinating grain.

Installing a valve directly in the product tube increases the indicated effect, as it prevents

the accumulation of grain in the latter and prevents its clogging, which makes it possible to increase the reliability of the unloading of the locking rocking apparatus.
