Definitions
- the invention relates to a method for the continuous malting of cereal grain material, in which the material coming from a feed device is applied to ventilation, cooling, humidifying and drying media and moving downward by gravity as a material flow, predominantly on inclined conveyor tracks with alternating direction of movement is discharged as malt through a discharge device.
- the crop flow forms a downward flowing crop layer.
- the invention further relates to a plant for carrying out the method according to the invention.
- the inclined conveyor tracks consisting of seven, shown in DE 3020511 AI, would have to have a length in the running direction of 10 m or more for high performances, as are achieved today by batch plants (50,000 t of malt / year and more). At the lower end of the inclined conveyor tracks, this length would lead to a considerable thrust pressure against the delimiting transverse wall or the material itself, which is substantially and thus disadvantageously above the usual ground pressure, for example. B. would be a 1.5 m high germinating layer of good and beyond that would not be manageable in the event of operational disruptions.
- the object of the invention is to develop a method and a system for continuous malting, which ensures reliable continuous operation despite the low construction costs and the low energy requirement.
- the combinations of features specified in claims 1, 20, 21, 24, 25, 26, 29, 32, 33 are proposed.
- Advantageous refinements and developments of the invention result from the dependent claims.
- An essential solution of the invention is that the downward flowing good layer between two conveyor tracks with different directions of movement is divided in sections at least into an upper and a lower partial flow and that the partial flows are then brought together again. In this way it is achieved that no core flow zones are formed in the transition area between the conveyor tracks, which could lead to disturbances in the mass flow.
- a further improvement in this regard is achieved in that flow bodies filling stagnation zones are assigned to the conveyor tracks and the transition regions between the conveyor tracks extending longitudinally and transversely to the flow direction of the material flow.
- the short inclined conveyor tracks on which the layer of material slides in alternating directions of movement are determined with regard to the interaction of their inclination angles and their lengths in that the thrust pressure exerted on the material to be malted in the lower end region of the conveyor belt within the transition region of the layer of material approximately corresponds to that due to the vertical height of the product layer, pressure on the product near the running surface of the inclined conveyor track or in the transition area to the next conveyor track corresponds.
- the process air can be guided in such a way that it alternately penetrates the material layer once from the top and then again from the bottom.
- the conveyor tracks and their transition areas from the top are placed between a locked discharge device at the bottom and a feed device at the top with a good layer of dry storage material, such as, for. B. finished malt or barley.
- a good layer of dry storage material such as, for. B. finished malt or barley.
- the feed device is followed by the downward moving material layer of the grain to be malted and occupies the conveyor track according to the conveyor track, with the corresponding onset and then continued exposure to process media, in order to be discharged separately after reaching the discharge device.
- the process is reversed, but the process is carried out with significantly less dry goods.
- cooling elements which are lengthwise or transversely extended above the oblique conveyor tracks in the good for energy-saving contact cooling and likewise to support the heating when swelling in the material are stretched lengthwise or transversely for energy-saving contact heating, which are also used in the subsequent one Passing through radiator roof dryers for kilning is possible in an energy-saving manner. It is also proposed to cool well-touched walls and conveyor tracks in the germ area or to heat them in the withering area.
- the impounding zones are filled by means of these flow bodies in such a way that their surfaces, which are designed as steep inclines or fillets, in cooperation with the above-mentioned material layer dividers, allow a completely residue-free flow of the material layer in the mass flow between conveyor tracks of alternating directions of movement.
- a further advantageous embodiment of the invention provides that on both sides of the slipping material layer slipping with alternating direction of movement extend lateral channels for air guidance and inspection, which are each open laterally to the space from the top of a slipping material layer and the underside of the slope arranged above it is limited.
- the production capacity of the malting plant according to the invention can be significantly increased, and thus, both by extending the depth of the inclined conveyor tracks transversely to the running direction of the material layer and by parallel, mirror-image arrangement of the same systems with the omission of intermediate or partition walls but with the arrangement of accessible side channels extending therebetween meet the practical requirements for high production output
- the adaptation of the treatment time when germinating, fading and drying is only achieved by raising or lowering the throughput, with the omission of adjusting or regulating flaps and with the layer height always being advantageous.
- 1 is a diagram of a plant for the continuous malting of cereal grain
- Fig. 2 shows a section through three lower germination stages without sieves and subsequent wilting stages
- Fig. 3 shows a section along the line I - I in
- FIG. 4 shows a section through three germination stages with crop layer dividers in an enlarged view compared to FIG. 2
- the system for continuous malting shown schematically in FIG. 1 has two systems arranged in mirror image to one another without a partition, with an upstream dry soft area 34, an adjoining germ area 35 with four germ levels, followed by a withering area 36, one as a radiator Roof dryer formed drying area 37 and a cooling area 38.
- the dry material conveyor 32 fills the entire system with dry material, such as, for example, with the discharge device 21 closed.
- dry material such as, for example, with the discharge device 21 closed.
- the discharge device 21 is inserted at the bottom and discharges the dry material, from which the material to be malted continuously from above, area by area filling follows.
- the discharge rate of the discharge device 21 is regulated by electrically responsive fill level sensors 3, so that the fill level in the feed container 1 always remains the same.
- This fill level is maintained by the open screw thread 2, which is used for depth distribution and which cleans itself through constant contact with the moist material.
- the subsequent conveying path for the malt storage is set. Since the process media are only switched on one after the other for the material to be malted, the dry material used can be returned undamaged in silo cells. This is important because the amount in the approximately seven-day filling process z. B. with a malting capacity of 50,000 t / year is about 1,400 t of barley. The funding of this amount for filling and emptying can, however, be accepted, since it should normally only take place once a year and considerably simplify the direction enabled. At the end of operation, the seal only needs to be filled with dry goods two steps above the last product to be malted.
- the germination fans 45, the cooling register 46, the drying fan 43, the heat recovery system 42, the wilting fan 30, the heating register 44 and the cooling fan 41 are constantly in operation, the automatically regulating flaps 47 and 48 fulfilling their function for air distribution. Since the systems are arranged in mirror image, the side channels 25 are acted upon by supply cross-channels 26, that of the Schwelk sieves by the supply cross-channel 27, while the exhaust air is collected by discharge cross-channels 28 or by the recovery cross-channel 29 or one Collective cross channel 51 takes place.
- the feed container 1 which is open at the bottom, delivers the supplied wet material coming from the soft device 40 at a defined height as a good layer 54 for dry rest in the dry soft area 34.
- the process air penetrates in the dry soft region 34 and the subsequent germ region 35 from the side channels 25, which are acted on at the end face, in the entire depth to the plane of the drawing through the openings 52 into the surface of the good layer 54 and partially escapes upwards through the transfer area into the side channels opposite and from there the front openings 49 to the outside, and partly downwards through the transfer area into the side channels opposite and from there also through openings 49 to the outside or - controlled by the automatic flaps 47 - to the openings - lo ⁇
- embedded cooling elements through which the coolant flows can be provided, at intervals and to the direction of travel of the material, extending longitudinally or transversely, in a stationary or movable manner.
- the good layer 54 flows slowly along the flat heat sinks 14. Since the grains are continuously supplied with make-up water by conventional spraying devices 31 and generate additional surface moisture through breathing or are highly conductive due to their own high humidity of approx. 44% H 2 O content, an energy-saving cold transition takes place along the heat sinks achieved by contact cooling, which is supported by the simultaneous penetration by cooling air and evaporative cooling.
- Excess splash water can be collected and drained through suitably designed perforations and gutters 33 extending in depth to the plane of the drawing.
- intermediate carriers 7 are provided which have longitudinal roofs 15 and flow bodies 8 with steep slopes 9 and / or fillets. gen 12 to the inclined conveyor track 4 out.
- the corner-filling flow bodies 8 have fillets 10 or multiply kinked transition surfaces in order to prevent grains from getting stuck in the corners and forming germinating or moldy nests.
- the throats of the transition regions extending transversely to the running direction between the supports 6 and the inclined conveyor tracks 4 have flow bodies 8 with a strong rounding 10 or a multiply bent transition surface.
- These flow bodies can be designed as solid or hollow bodies and can be provided separately or integrated in the building.
- flow bodies 11 designed as solid or hollow bodies with steep inclines or fillets are preferably made according to the invention 10 suggested.
- the germinating process causes the downward-moving material layer 54 to swell on its way from the top of an inclined conveyor track 4 to the transition opening to the next inclined conveyor track.
- the displaceable flow bodies 11 can be adapted to the respective upper side of the flowing material and can then be left in the position for continuous operation which prevents the formation of dead material nests.
- the need for cooling air for the germination process can be considerably reduced by the contact cooling by means of heat sinks embedded in the material layers 54 and through which coolant flows and / or in supports 6, in or under inclined conveying tracks 4, in intermediate supports 7 and material layer dividers.
- Investment, space and power requirements for germ fans and cooling registers decrease accordingly. This is offset by the investment costs for the heat sink and tube.
- the saving in operating costs outweighs the proposed system in continuous operation. If e.g. For example, if half of the required cooling capacity is introduced by contact cooling, only about half of the usual air capacity is required, with a corresponding reduction in the current electricity costs.
- the theoretically required oxygen or air requirement for the actual germination process is only 192 kg 0 2 per t barley or correspondingly 960 kg or approx. 800 m 3 air, distributed z. B. over two soft days and 5 to 6 germ days.
- This calculable minimum amount of air would have to be supplied at least per t of barley for germination, whereby the 68 kg of CO 2 (approx. 140 m 3 ) formed by breathing should be removed and approx. 845,000 kJ / t of barley generated heat would have to be compensated by cooling.
- FIG. 2 the oblique conveyor tracks 4 of the lower germ region 35 with the possible smooth running surfaces without screens are shown in cross section.
- protruding rotating shafts 16 which are movable in two directions transversely to the flow of material and which are provided with mixing or loosening means, or in the region of the transfer openings between two conveyor tracks are extended parallel to the carriers 6 and rotating horizontal shafts which are equipped with mixing or loosening means 17 arranged, which can be formed as a tubular body and can be temporarily stored in intermediate carriers 7 even with a larger longitudinal extent.
- the germinated grain passes through the withering area 36.
- FIG. 2 it is shown that the warm air from the side channel 23, which extends in depth to the plane of the drawing, both through perforated perforated screens and through ventilation roofs 22 into the downward sliding material layer 54 can reach. Since warm air penetrating through sieve air very quickly becomes saturated with moisture up to the maximum limit and then only penetrates the resistive material layer located above it, the air introduction proposed according to the invention in a second level within the material layer is a faster drying effect and lower power consumption achievable.
- the ventilation roof 22 is open on both ends and is therefore easy during the Operating clean.
- the smoldering gap is fed through the opposite side channels 25 to a recovery cross-channel and then to the heat recovery system 42, as shown in FIG. 1.
- the good layer 54 by means of radiators by means of contact heating to a substantial proportion of the required thermal energy.
- radiators are shown in FIGS. 2 and 3 as flat, spaced bodies 14 above the ventilation roofs 22.
- the ventilation roofs can also be designed as radiators.
- the inlet and outlet pipes for hot water or steam shown run in the accessible side channels 23 and 25, respectively. Due to the introduction of warm air in two levels and a proportionate supply of energy by means of contact heating, according to the invention, a much faster moisture removal and improved efficiency can also be achieved for the swelling area 36 compared to conventional processes.
- good layer dividers 55, 56 which are assigned to the transition area between two conveyor tracks and alternate running directions, are introduced, which are straight or kinked, and fixed or displaceable guide surfaces 57 can have.
- the surfaces of these good layer dividers can be straight or curved. They have a pointed or rounded upper cutting edge 59 and lower cutting edge 60 so that goods can flow around them in a self-cleaning manner without leaving nests or dead corners.
- the good layer dividers 55, 56 which preferably extend in the middle of the good layer horizontally across the running direction over the entire width of the conveyor tracks, are provided in the running direction of the good layer approximately parallel or also at a small angle to the respective conveying track giving off the good layer and extend with their upper cutting edge 59 approximately from Area above the conveyor edge 61 starting with its lower cutting edge 60 or the guide surface 57 approximately to the middle of the transition area.
- the good layer dividers 55, 56 can have cavities 58 for the passage of cooling or heating media and enable the protected overflow of the lower good layer area via the conveyor track edge 61 into the assigned half of the transition opening to the subsequent conveyor track.
- the upper half of the good layer is continued in an inclined direction above the good layer divider and can only flow downward between its lower end and the carrier 6 into the outer half of the transition area to the subsequent conveyor path and form the lower layer thereon.
- FIG. 37 Drawing plane extended mirror images arranged Germ / wilting systems shown without partitions or partitions.
- a drying area 37 which is formed as a roof dryer and followed by a cooling area 38, can follow below two mirror-image systems.
- the roof dryer alternately has heating compartments with radiators 18, drying compartments 19 and cooling compartments 20 and a discharge device 21.
- Automatically regulating flaps 48, a collecting cross-duct 51 with fresh air inlet and the smoldering fan 30, heating register 44 and supply cross-duct 27 are provided in the drying area 37. The latter distributes the heated smoldering air into the spaces below the sieve trays and into the side channels 23. Preheated air is likewise supplied to the rocking fan 30 from the heat recovery system by means of the return air side channels 39.
- heating compartments with radiators 18 and drying compartments 19 enables the known "sweating" of the grain material and thus a much easier and faster curing with less energy consumption, since the capillaries of the outer grain layers also reach 14 in the area of moisture removal 4 ⁇ % water content for the water exit from the inside of the grain to the top of the grain remain open.
- Drying area 37 and cooling area 38 with the interposition of a discharge device underneath the swelling area 36 and then a collecting conveyor, a disinfection device and an intermediate elevation can also be arranged separately as a roof, radiator or fluidized bed dryer in addition to the germination / withering areas.
- the discharge capacity of the discharge device under the withering area is controlled by the electrically responsive sensors 3 of the feed container 1, while the selected dryer has its own control device for constant filling with fluctuating throughput.
- the above-mentioned germ separation between the discharge device and intermediate elevation to the selected dryer which is not shown here for warm material, can advantageously be switched on for drying out.
- the gradation of the temperatures for various types of malt required for drying out can be selected and regulated particularly advantageously in the case of the relatively high radiator or roof dryers which extend through several floors.
- the invention relates to a method and a plant for the continuous malting of cereal grain.
- a feed device predominantly on inclined conveyor tracks with alternating directions of movement
- the material is acted upon as a stream of material by gravity, moving downwards from ventilation, cooling, humidification and drying media and discharged through a discharge device as wilting or finished malt.
- the crop flow forms a downward flowing material layer which is divided into sections in the transfer area between two conveyor tracks into an upper and a lower partial flow, the partial flows then being brought together again.
- the continuous process offers significant economic advantages in terms of the space required and the energy required.
