Furthermore, the Invention relates .to a method of operating such a drying system for hoik mate?“isi. in drying, systems of tbs above-mendoned type, agricultural products, Ih particuiar grates such as cereals, end osabe, but also rapeseed or sunflower, are dried with warm air. These drying precesses hévé bemmé established In the agt icuitural field, because a hlgh-pertermanoe, high-quality and careful drying of the agricultural grains is possible. Also, the cspitei and. operating ousts are tew by comparison with other drying processes, such as ireete drying, vacuum drying or radiant drying. In general the so-called continuous, flow dryer has become established, in which the drying sones are teresed by a vertical drying tevteror a drying column through which bulk material to be dried ;s passed downwards horn the top.
The air passes transversely through thss dry!ng tower. Heated supply air flows .in at one side of the drying tower and then -.flows through the bulk product there, in this case the product or bulk material warms up and releases its moisture content to the -warm air sweeping past The bulk materia! dries, Ih contrast, the air pools- and is humidified, The moist air escapes as exhaust air at the other side of the drying tewer. In this case the supply air and/or exhaust air is conveyed by motor-driven fans which are arranged- in the air supply end/or the air-extractor, A drying device for bulk .materiéi, such as grain, is known from Öb-Uted 3004 018 45¾ in which a hot air generator and a plurality of drying levels arranged one above the other as well as sir guide channels ter supplying air at different températures te different drying levels are provided. At least two drying levels are each associated with their own hot air generator, wherein the hot air generators can be operated independently of one another, in this case the air is supplied by a common air supply shaft and is extracted by a respective fan on the side of a guide shaft for the hoik material- dpposlt« the hat air .generator, Such air ducting. Is technically comparatively complex end not very energy-efficient. FR-A-ö 454 5B9 discloses a. grain dryer according to- the preamble to claim Î as weil as a method according to the preamble to claim 6, wherein air is drawn through a plurality of drying sections by weans of on© single air suctiorr device. In this case the air is suppilM' by two air introduction devises. -One of the sir Irittoductlori devices-leads to -a first sir heater and Into a central part of the drying sections. The second air Introduction device guides supply air without air heating to two drying sections which serve for cooling of the dried' grains. Furthermore the second air introduction device guides supply air to -s farther air heater 'this supply air is guided into a lower part of the drying sections and also to s third air heater, through which this supply sir is then admixed with the exhaust air horn the central perl of the drying sections, m order to guide It into so upper part of the drying sections, furthermore, a part of the drying sections with a third air introduction device which serves for intermediate cooling of the grains is also provided between the upper part and the central.part of the drying sections.. fr-a-2 56? 636 discloses a drying system for granular goods, in which heated air is drawn through an upper part of the drying sections by means of a first air suction device, for a hover parr of the drymg zones cold cooling air and likewise the heated air are supplied, For this purpose the hot sir is supplied and heated by -means of one single air heater. By means of a second air suction device exhaust air is drawn out of the lower part of the drying sections and this exhaust air is returned to- the single air heater, This futur non edioxst ai v I sh < »ehe rid m * v sing e ou ho =s or m ·,> | vwose feuded into the- lower pert and the upper part of the drying rones. ^Idttoacect^
According to the invention a drying system for bulk material Is created. in particular for agricultural grains, with a plurality- of drying zones through which hulk material to he drierf is- successively passed. The drying system -s provided with an air duct for passing air through the drying zones, wherein an air introduction device is provided for introducing fresh air from the surroundings of the drying system as supply air info a first part of the drying zones, furthermore in the air duct an air forwarding dévice is provided for forwarding exhaust a»r from the fast pert .4 me drying zones as supply air snto a second part' of the drying zones. Furthermore, a- the air duct of the drying system accordirsg to the invention fer hulk matériái a further air introduction device Is provided for introducing further fresh sir from the surroundings of the drying system info the supply sir to the second port of the drying tones or into the second pert of the drying sones. in the drymg system according to the invention, ss also in conventional systems, fresh ei? is introduced by a first air introduction device on the drying column into a first pert of the drying zones there. This air exits again as exhaust air oh the other side and is then forwarder! as supply air to a second part of the drying zones. In this -way the already slightly humidified air from the first part of the drying tones can he used again in the second part of the drying zones and can thereby be humidified. A high energy efficiency should be achieved with this fersvarding of exhaust air as supply ait into second dry leg sones.
At the same time, with this forwarding of exhaust air from one gart as supply air into another pert of the drying sones the problem arises that the forwarded air is comparatively cold and in order to absorb further moisture its hcmtidfty level must be improved, and In particular must he heated. This heating could be achieved by passing the forwarded air through an air heater. However, with such heating of the air which has already been passed through drying tones the problem arises that this air is laden with dust ansi suspended matter from the hulk material from the first part of the drying sones. This dust or suspended metier is very highly flammable, so that in known drying systems with such processes fires occur repeatedly. In order to at least reduce the fire risk, In the known drying systems the forwarded air is often subjected todust extraction.
According to the Invention, on the other hand, the forwarded: exhaust sir from one part of the drying tones is Improved with regard to its humidity level in that further fresh am from the surroundings of the drying system is supphed os added to this exhaust air. The added fresh air has a tower humidity leve! end thus also reduces the humidity level of the resulting air mixture, f urthermore, wnh the forwarding of exhaust an according to the invention with simultaneous admixture of fresh air into the second part of the drying zones a particusariy efficient dust reduction ?s produced. The exhaust air from the first part of the drying zones according to the invention can be more heavily dustdadeo than in known drying systems, sínre the above-mentioned ore risk does not exist. The drying system according to the invention can ha operated so that in the first part of the drying zenes It is hotter than In conventional drying systems. Whilst in conventional drying systems, it Is usual to operate this first part of the drying zones at a temperature of dû X to 125 X, the drying system according to the invention van advantageously be opera tod at a temperature of 130 X to ISO X, particularly preferably 140 X to 15Ö X, In the first pan the drying zones Since the enbre exhaust air horn ihe Wt -sr port of the drying zones is reused In the second part of the drying zones, the stronger .heating in the first part dons not result in any energy loss hot rather, it improves the drying of the materiel there. This results in en advantageous configuration, since the dryer a material is, the more it can tolerate high temperatures. Thus the principle according to the invention produces higher throughputs than conventional principles. in tise drying system according to the Invention this comparatively high dust contamination In the second part of the drying zenes can then be returned to the material to be dried there: This is a further advantage of the concept according: to the invention in addition to the saving of energy;
According to the invention, for the above-mentioned reasons this further supply of fresh air is itself also heated., wherein the heating takes place Independently of the forwarded exhaust air from the first pert of the drying zones, for this purpose in the drying system according to the invention an air heater is provided for heating the first fresh sir supplied by the air Introduction device and a further, second air heater is provided for heating the further, second fresh air supplied by the further air introduction device, in this case It is particularly preferred; that with the further air introduction device and the further air heater, an air mixture of exhaust air from the 'first part of the drying zones and further fresh air from the surroundings of the drying system .is adjustable to a temperature between löd X and 145 X, In parpeniar between ltd X and Ü25 X. These temperature ranges are particularly advantageous with regard to the supply of further, heated fresh av according to the Invention for heating exhaust air from a first part of the drying zones with regard to the total energy balance of such a drying system.
For convoying the air on the drying system according to the invention an air auction device or fan is provided according to the invention for drawing exhaust w from the second part of the drying zones and additionally a further air -suction device is provided for drawing the exhaust air from the first part of the drying zones. With the two an" suctton devices in each case s suchen is produced by the first part of the drymg zones sod a further suction is produced by the second part of the drying sonos, In this cose the W sir suction devices can he eorrtroHod independently of one another with regard to their suction capacity, so that the extraction of the exhaust air and the admixing of further fresh sir can be opflmally adopted to one soother, With the air suction device the exhaust air is conveyed in the direction of the second part of the drying rones, in order to he drawn in there as supply air togetlser with the further frosh Sir, With the suctipp of the further or second air surdon device the amount of further fresh air to he drawn in can he determined at the same time, io this connection It is advantageous to provide a throttle valve or regulating valve on the further or second air iotroductioh device, with which the air resistance for the ait streams of forwarded exhaust air and supplied further frést? air can be influenced,
Furtherrrmre, for a high energy yield the drying system according to the invention Is preferably an air recycling system or an air recirculation system for returning exhaust air from the first part of the drying tones bach as supply an snto the first part of the drying zones, A third air introduction device is preferably provided on this air recirculation system for introducing fresh air from the surroundings of the drying system Into a third part of the drying tones. This third pert of the drying zones Is preferably the lowermost portion of the drying column through which the bulk material flows last and which is used as the so-called cooling region for the bulk material,
Gn the drying column the lower portion, before or above the cooling region In the flow direction of the bulk matériái, is preferably provided as the first part of the drying sones. The second part of the drying sones is then the upper region of the drying column arranged above tho first part.
Further-mere., in tbs drying system according to the invention an air recycling system is advantageously provided lor returning exhaust air from the third part of the drying tones as supply air into the first part of the drying tones, "This type of alt recycling system forms a component of the above-mentioned air recycling system, which is advantageous in terms of energy, In the last portion of the drying column. furthermore, according to the invention a method for· operating a drying system lor bulk material is created, in particular for agricultural grains, In which hulk material to be dried Is passed successively through a plurality of drying zones and air Is guided through thé drying cones, in ibis esse fresh élt írom the surroundings -óf thé drying system Is Introduced as supply sir into a first part of the drying sonos. Ön so air forwarding devise exhaust sir is forwarded from the first part of the drying sones as supply atr into a second part of the drying rones. Furthermore, on a further sir Introduction device further fresh air from the surroundings of the drying system Is introduced info the supply air to the second part of the drying senes or into the second part of the drying .rones. .According to thé invention, in such a method for operating a drying system corresponding to the ahovo-mentioned design the fresh air supplied by the air Introduction device is heated on an sir beater and the further fresh sir supplied by the further air introduction device is heated on a further air heater.

An exemplary embodiment of the solution according to the Invention is explained in greater detail with reference to the appended schematic drawings. In the drawings; figure 1 shows a simplified iongiiudinal section through a dfyuig system for agricultural grains according to the prior art;
Figure 2 shows a simplified longitudinal section of a first embodiment of a drying system for agricultural grains according to the odor art;
Figure 3 shows a simpiilied longitudinal section of a second embodiment of a drying system lor agricultural grains according to l:he invention and
Figure 4 shows a simplified longitudinal section of a third embodiment oi a drying system for agricultural grains according to the invention. .QotalLedJescrg^ A drying system ÍÖ for agricultural grains comprises as essential components a drying column 32 with drying zones T.ib to Γ.Ι.. an mr supply 34 as well as an ah discharge so.
On thé upper side of the drying column 12 is located a filling opening. 18 for bulk material 20 to be dnnn. sn thh case rnaùe grains. Due to the gravity acting on it, thé bulk material 20 passes successively-through-the drying xooes T.1S to Tl of the drying -column 1.2 from the top to the bottom, in this case the bulk material 20 trickles through roof-shaped air shafts which are: each open at the bottons {not shown in greater detail).
The a«r supply 14 is designed with a lu\t -er introduction device 22 which is formed as an air supply shaft at the lower end region of the drying system TO, on the left of figure 1. Fresh air 24 from the surroundings el <hn drying system TO passes through the third air introduction device 32 into a first part 26 of the drying zones Tt§ to TI; namely Into the drying tones Tg to T.3. This fresh air 24 at the air introduction device 22 is heated in a first air heater 2.8, The heated fresh air 24 Is drawn in as supply' air through the first port .26 of the drying tones TT6 to TT- It adsorbs moisture from the bulk material 2Ö there end is discharged again as humidified exhaust air 3Ö oom the drying column 12 at the right -hand side of these drying tones T8 toT3.
This exhaust, air 30' is guided by an air forwarding device .3.2 in the form of a fan (In particular an axial fan or a radlsi fan) nr air suction device 34 vertical upwards on the left-hand side of the drying zones T1S to TO which form -a second part 38 of the drying torsos T.16 to TT. A second air heater 38 by which the exhaust air 30,. which Is passed through the air suction device 34 and ss cooled in the meantlmo, is heated again to a temperature of approximately 140 8C, is associated^ with the air forwarding device 32 located after or downstream of the air suction device '34 in the how direction. With such boating of the exhaust air 30 by means of the sir beater 33,. there Is a high risk of ignition and fire, because the exhaust air 30 in the drying tones T8 to Tl has been enriched not only with moisture but also with dust and suspended matter.
The exhaust air 30 which, is heated again then passes through the second part 36 of the drying zones T16 to TI and flews off as exhaust air 40 through the air discharge !6„ For this purpose the air discharge 3.6 has an air suction device 42 In the form of an axial fan or a radial fan, by which the exhaust air 40 is drawn off from the drying zones TX8 to T9.
Figures 2 to <· i Show solutions according to the invention for a drying system .10 in which the air forwarding device 32 is configured differently. The air forwarding device 32 according to Figure 2 has an air suction device 34 by which exhaust air 30 from the drying rones T8 to 1'3 is conveyed to the drying .tones fib to T9 without thss exhaust an' 30 being Mated in the process. Io order to improve the humidity isvet oi the supply air to be fed. Into the· drying zones Tib to T9 -by comparison with the high humidity level of the exhaust ah 30, further fresh air 46 from the surroundings of the drymg system lit is introduced by means of a further olr lotreduction device 44 into an air guide channel 46 above the: air· suction device 341 in this air guide channel. 43 is located a second air heetet $0 accordlhg to the invention, by means of which the further fresh sir 46 supplied by the further air introduction device 44 is heated. Since this fresh a»r 46 is oot lade« with dust or suspended matter, there is -no fire risk during such heating of further fresh air 46, in. the air guide channel 4b the heated further frosh air 4b Is mixed with the .exhaust air 3Ö In such a way that eyeraii a temperature, of the: sir mixture of approximately 118 X to 125 X is set. Then, similar to the drying system 10 .according to figure Î, the air mixture Is conveyed by means of an air suction device 42 and possibly by means of a dust extractor foot shown) on the air discharge 16 through the dryi ng sones Tib to T9 end outwards into the surroundings of the drying system 18,
Such a design with a further air Introduction device 44 for further frosh air 4b as well as an associated air guide channel 4g with a second air heater SO arranged therein is also provided in the drying systems 10 according to figures 3 and 4.
The Ofysng sones T2 and ''1 of the drying column .12 «ccordiog to rigors; 2 are •designed as a third part 52 of the drying rones T1S to T1 or as a so-called cooling region with Individual cooling sones into which frosh air 54 can be- supplie# directly from the exterior fey means of a third air introdpetioh device 66, In the drying systems 10 according to figures 1 and 2 this fresh air S4 passes through the drying zones T2 and Tl and then enters the air suction device ,34 as exhaust air 38. figure g shows an embodiment of a drying system 10 in which the fresh si? 54 Is supplied to the drying sones T2 and Π fey the third air introduction device 56 from the exterior on the other side of the drying coiurnn 12, After this the resulting exhaust air is guided out of the drying zones T2 and Tl into a further air guide channel 66 bn the side erf the air supply 14. in this case the further air guide channel 60 Is located above or downstream of the first air heater 23, so that the exhaust air from the drying zones T2 and Tl is admixed directly with the already hooted fresh air 24 and is then supplied to the drying rones f S to 13 as supply air.
