Title:

Method and apparatus for malting grains β

Description

The invention relates to a method for malting barley and other grains with several treatment rooms for the Weiohen and germinating, in which the malting process is carried out using approximately equal treatment periods. the The length of a treatment period is determined, for example, by the period between two turning or loosening processes This procedure creates an air-gas mixture in some treatment rooms BU led, which at least partially already has been led through other treatment rooms with absorption of carbonic acid

Well-known proposals of this kind are that the air, the dea is supplied to the first treatment room used for germination, To bring them closer to one another to all treatment rooms, in <they feued Mälaung is more advanced, so that in the

The malting material in the last malting period is an air-gas mixture is supplied with very little oxygen and a lot of carbonic acid, which serves to stimulate external growth (root growth) in the To hold back the course of the malting without adversely affecting the internal transformation of the grain.

Such treatments are suggested for malting in so-called Saladin branches as well as in malting towers, regardless of whether the good during the whole malting process in one and the same Container remains or whether it is moved to a different treatment room at the end of each period. This well-known Procedure has the disadvantage that the painting material during each The following treatment period cannot be treated individually, according to its specific characteristics can be attributed to climate and soil, among other things, under their influence the grains have grown - »- This well-known process Furthermore, it can hardly be explained in practice, at least Malting of the first switch (pre-switch) only a part, e.g. $ 38 of the water required for malting and then later should be subjected to another switch (resteeping)

The invention aims at the malting process each Adapt the nature of the malted material and take this into account ■ on the differences in quality of the ifiälzggut, which is, for example, in the fourth treatment period is opposite to the malted material,

or

which is in the 5th, 5th * β * & 6th treatment period «

For the purpose mentioned, the invention consists in that the supply and discharge of an air-gas mixture for each treatment room regardless of the supply and discharge of an air-gas mixture of the other treatment rooms. This can be done, for example, by that each treatment room is assigned its own fan, which is independent of the fans in the other treatment rooms can work.

The method can be carried out in such a way that the exhaust gas from one treatment room, which has a carbonic acid content, is fed to another treatment room which precedes laterally by several periods, separated from the exhaust gases from other treatment rooms. In this way the method can be applied when the Mälzgut remains during the 2 ^ESAM ^ ^s treatment time in the same treatment room, and even if it is transported to another treatment chamber at 3nde each treatment period, which for example. The so-called (Durmmälzen happens. The invention The process can also be implemented using closed tjaladin boxes, but this type of implementation of the process according to the invention requires a very large number of air-gas lines with valves.

The following modification of the invention is therefore for tower malting Preferable method, which is characterized in that the exhaust gases from all or most of the treatment rooms, possibly under Admixture of fresh air, a riser shaft with a large cross-section

be fed from below, in which the air rises faster than the carbonic acid content, and that this shaft that in the Treatment rooms to be introduced air-gas mixture at taps of different heights is taken in such a way that from the higher lying Taps higher-lying treatment rooms and lower-lying treatment rooms from lower taps be taken care of.

In order to perfect the special treatment of each individual malted product, the air-gas mixture supplied to each treatment room is also advantageously independent of the other treatment rooms supplied, air-gas mixture heated or cooled. Here, the cooling is of "particular importance * If namely the air-gas mixture in the riser duct is warm, e.g. has a temperature of 60 °, it is cooled down to e.g. 25 ° completely saturated with moisture. In any case, foreign gas, for example carbonic acid, can also be added to the air / gas mixture that has not been taken from a treatment room that was in an earlier treatment period

A malting tower suitable for the second variant described is preferably designed in such a way that each treatment space can be sealed off from the above and below it, is provided with an air-gas supply line and an air-gas discharge line, a fan being arranged in one of the two, and that the drainage pipes, apart from. - ^j

the uppermost treatment rooms, lead large in a vertical air gas chute cross-section, the lower end with a corresponding riser duct of large cross-section comparable is prevented ^v, from which branch off the supply lines for the individual treatment room approximately at the level of these spaces.

A tower of the type mentioned offers the advantage, among other things, that it is aur Execution not only of the method according to the invention, but is suitable for carrying out almost all known malting processes. It also has the advantage that it can be used during operation can be cleaned. This happens in the way that during * the uppermost treatment room is not filled for a period. In this way, the second treatment room remains for the next period, in the third period the third treatment room, and so on, empty, so that during the time that the malting Process takes, the possibility exists of all

To clean rooms one by one, this work can be done by a one-IPersoi,

of the tower enters.

The special treatment of the individual treatment rooms can be according to Further development of the method according to the invention can be reinforced by the fact that the individual treatment rooms are specifically i.e. independent of other treatment rooms, Premdyase e.g. Oxygen or carbon are supplied. Instead of the foreign gases, carbon dioxide can also be supplied in a targeted manner

because of their weight. Gases deposited in the riser Has. Oxygen, or carbonic acid or foreign gases "are then supplied to each treatment room depending on" its needs, namely, the need for such a special allocation arises either from the composition of the relevant Treatment room supplied gas and / or from the composition of the gas discharged from it. The respective composition the supplied or discharged gas can be continuously measured according to the invention with Dräger apparatus, so that the Control of the supply and discharge of carbon, oxygen or 3 remnant gases also depending on the respective measurement results the Dräger apparatus can take place continuously.

According to the invention, soaking and germination are considered as a continuous, understood and treated by no incision separate development process. This unified process in which For example, carbonic acid is already produced during the Yorweiche, but it can be divided into two phases, the first mainly consists of biological (enzymatic) development, where the malting material needs water, moist air and oxygen (air). During the second (chemical or solution) During this phase, the malting needs to be continuously supplemented with water and moisture in the surrounding air-gas mixture. It develops carbonic acid and other gases under the influence of which it may rot and take on a bad odor. That is why it is also in the second phase let periodic evacuation of these gases be desirable, which he-

So in a later treatment period, for example in a treatment room of the malting tower, you can first water, i.e. that Mal ζ put it under water for 6 hours, then give it a gas-air mixture to feed for 12 hours.

Further details of the invention can be found in the description and drawing and claims to be seen.

The drawing shows a malting tower, based on which the inventive Procedure is described.

The malting tower shown shows eleven treatment rooms one below the other A to L, which are used for soaking and / or germination.

In a manner known per se, YäTesen treatment rooms can be further treatment rooms * for Schwelken and Darren Y foresee. «All treatment rooms are designed in the same way and are in the tower. housed, the walls of which are denoted by 1. In every treatment room, the strong line 2 means a tub that can be sealed against the wall on all sides, but can be tilted. A water-permeable shelf 3 is arranged over the bottom of the tub 2 in a manner known per se. Since the tub is sealed on all sides with respect to the tower walls, water can be filled up to the height of the water level 4 above it. The space between the tub base 2 and the tray base 3 is connected to a riser connection 5, from which excess water can be discharged through a discharge line 6. The normal one

Inlet water is drained into the treatment rooms but by water pipes, not shown. The supply of air or an air-gas mixture takes place through supply lines 7. A controllable fan 8 is built into each supply line. The top three fans suck from room 9 Fresh air on, through thermal regulation devices 10, the can be used either for heating or for cooling. The discharge line. 6 of the uppermost treatment room opens into one Room 11, which has a connection with the outside air. The remaining drain lines 6 'lead into a chute 12 with a large cross-section, the one below at 11a with a riser shaft 13 of very large cross-section connected is. From diesel riser branches feeder lines 7, in each of which a fan 8 and a heat regulating device 10 is installed. Both in the chute 12 g.ls Also in the riser shaft 13 there are water chambers 14 which ensure that the air-gas mixture in the spaces 12 and 13 are always fully saturated with water. Excess water from this fall and riser shaft can be withdrawn from below in a manner not shown. At the chute 12 is both above and below an air regulation flap 15 is provided, with the help of which fresh air is introduced or excess air-gas mixture can be discharged "

The tubs 2 probably seal against the wall of the tower, but can be rotated so that the quantities of malted material lying on their hordes fall up into the treatment room below. ·

The circles 16 mean Lient incidence openings. The circles 17 mean door openings. The associated doors are double. Both should be opened for boarding. For Sinschauen and insertion of tools is sufficient, the opening of the upper door, which has the advantage that the upper door can be opened even when the tank 2 is filled with water or the tray is covered with Mälzgut _t By this arrangement, therefore, the height of each Treatment room kept low

The malt is initially stored above the uppermost treatment room (number 19) · From there it is transferred to the uppermost Treatment room A introduced, which is to work, for example, as a switch, For this purpose it is filled with water up to level 4. If air is blown in by the fan 8 after the water has been drained, so it passes through the soft material and through the tray 3 downwards, from where it rises again via the nozzle 5 and,

due to their relatively high speed with entrainment of carbon dioxide formed, through the discharge pipe 6 into the space 11 and vog. there escapes into the IPreie. In the one below Treatment room B is now to be germinated, for example. The tub is then not filled with water, so that the malted material the tray base 3 can easily be flushed through by the air that is supplied by its fan 8. The discharged air-gas mixture £ then rode through the discharge line 6 into the chute 12. As a modification of the. The drawing can also be made in such a way that the exhaust gas from the uppermost treatment room would be led into the IPall shaft

Should now the treatment room C below it again are used as a switch, it is treated as the Eaum A described above, with the one to be removed However, the air-gas mixture is not fed to the outside air, but also into the lall shaft 12. The deep ones Rooms D and ff can now be used for germination or soaking as desired. The exhaust air is out of each treatment room into the chute 12; there the air-carbonic acid mixture sinks due to the large cross-section only slowly. The carbon dioxide collects mainly below and enters the air of the Mixture due to the large cross-section of the riser 13 faster upwards than the carbonic acid, the due to their higher weight remains running down. This ensures that the treatment room D and the ' underlying non-identical air-gas mixtures are supplied. The upper treatment room D receives namely a Mixture that contains much less carbonic acid than the treatment rooms below. The greatest amount of The lowest treatment room L.

Since the air-gas mixture rising in the riser shaft 13 has already passed through germ trays for the most part there is an elevated temperature. After it is then sprinkled with water through the nozzles 14, it cools down in the cooling units 10 actually one
