Definitions
- the invention relates to a method for drying and cooling moist crystal sugar masses, especially fine grain size, fructose, dextrose or the like. With the features of the preamble of claim 1 and a device for carrying out this method.
- a device (prospectus from FMC Corp., Colmar, PA) which has an elongated, essentially horizontally oriented drum, at one end of which the moist sugar mass is fed in with the aid of a screw conveyor.
- the drum consists of an outer drum body, in which an inner drum body is arranged, the cross-sectional diameter of which widens continuously from the entry end to the discharge end of the drum, as a result of which the sugar mass receives a small migration component in the direction of the drum axis when the drum is rotated slowly.
- the inner drum is formed by a multiplicity of ventilation flaps which overlap in the direction of rotation and delimit a multiplicity of ventilation gaps, through which drying or cooling air enters the interior of the drum from the space between the two drums can.
- the ventilation flaps are fastened to the inner circumference of the outer drum body by means of radial webs, so that the space between the two drums is delimited by a plurality of circumferentially separate air guide channels parallel to the axis of the drum.
- the drum is operated in such a way that, depending on the added sugar mass, a sugar flow forms in the drum, which essentially remains in the lower third of the drum.
- the sugar flow is supported by the air flaps on the inner drum.
- frame-fixed supply devices for heated drying air and for cooling air are arranged such that the heated drying air initially only enters the first part of the drum, the drying zone, while the cooling air can only enter the last part of the drum, the cooling zone.
- the frame-fixed air inlets are arranged so that the air can only enter the longitudinal channels formed between adjacent ventilation flaps and their webs, which are each just below the sugar flow, so that the drying air and the cooling air each only through the interior of the drum the sugar stream can enter.
- the sugar mass Due to the flowability of the sugar mass, it forms a flat interface in the drum on the top of the sugar mass flow, which is assigned to the drum cross section in the form of a secant.
- the areas of greater thickness of the layer thus form an increased flow resistance for the air. Since the sugar mass moves in the form of a compact stream through the length of the drum, the drying and cooling performance is low. The sugar masses therefore require a relatively long residence time in the drum in order to be dried and cooled sufficiently.
- flowable material can be dried particularly gently in so-called fluidized bed processes.
- fluidized bed processes are used to a large extent in the production of instant products in which granules are formed while the applied binder is simultaneously dried.
- the arrangement of the fluidization bed on a plane oriented along a secant of the drum cross-section ensures that the layer height in the fluidization bed is uniform both in the longitudinal direction of the drum and transversely thereto, so that the cooling air can attack the sugar particles equally effectively in all areas of this fluidization bed .
- the sugar particles are not held together in a more or less compact stream that rolls in a spiral to the outlet end of the drum, as is the case with the known dryer and cooler discussed at the beginning the case is. Rather, the sugar particles remain in finely divided, fluidized form in the fluidization bed before they preferably migrate to one side towards the inner wall of the drum and are again picked up by the revolving lifting blades, lifted up and made to run off.
- the cooling capacity is above all significantly increased.
- the result is that a high cooling capacity is achieved with small dimensions of the cooling zone and the cooling air speed can nevertheless be significantly reduced compared to conventional coolers to well below values of 2.5 m / sec. and preferably around 1.75 m / sec.
- the device-based solution of the invention takes place through the teaching of claims 5 and / or 6.
- the measures of claims 5 and 6 are preferably applied together to one device, since the performance of this device can be increased very considerably.
- the device designated overall by 1 according to FIG. 1 has an elongated drum 2.
- the axis 11 of the drum 2 is arranged slightly falling relative to the horizontal according to the angle 12, so that the discharge end 10 is slightly lower than the feed end 9 of the drum.
- the moist sugar masses are fed to the drum 2 at the feed end 9 by a feed device 5. At this end the mostly tempered drying air is also fed axially according to arrow 6. In drying zone 3, the direction of migration of drying air and sugar mass is the same.
- a cooling air box 15 is arranged in the cooling zone 4.
- the cooling air is supplied from the side of the discharge end 10 both to the cross section of the drum 2 and to the cooling air box 15 in accordance with the arrows 7.
- the dried and cooled sugar mass is discharged in the direction of arrow 8.
- the drying air and the cooling air are taken up in the middle of the drum by a device 13 which spirally discharges the exhaust air in the direction of arrow 14.
- the drum 2 is driven about its axis 11 at a slow speed.
- the feed end 9 of the drum 2 is shown in longitudinal section. This end is closed by a guide device fixed to the frame in the form of a guide body 24 which can be connected to a source of drying air.
- the guide device 24 is connected to the rotating drum via a sliding seal.
- the guide body fixed to the frame is penetrated by conveyor troughs 28, 29, which in the example shown run in two horizontal planes one above the other. Outside the guide device 24, the conveyor troughs 28, 29 extend into a feed hopper of the feed device 5.
- the feed hopper is divided into two areas by a partition wall 27, via which a conveyor 28 or 29 is loaded in each case.
- the trickle edges 30 and 31 are offset both in the direction of the cross-sectional height and in the direction of the axis 11 of the drum 2, so that separate veils in the mutual Distance and parallel to each other. In some cases it is also sufficient if only one conveyor with a single trickle edge is provided.
- the drying air flow is expanded by the guide device 24 and possibly by further internals 22, such as baffles, when entering the feeding end 9 of the drum 2 such that the air flows in and flows through the veil approximately vertically over its entire surface area in a uniform flow.
- the moist sugar mass which is fed to the feed hopper in accordance with arrow 25 and trickles into the interior of drum 2, subsequently migrates in a conventional manner through drying zone 3, which can be equipped with appropriate internals 21, 23 in the form of webs.
- the drying air is then taken up and removed in the device 13 according to FIG. 1, while the dried sugar mass passes through the device 13 from the drying zone 3 into the cooling zone 4.
- the drum 2 has on its inner wall a ring of lifting blades 45, the inward edges of which sweep over a common path, which is indicated by dash-dotted lines at 46 in FIG. 5.
- the sugar masses located in the lower part of the drum 2 are grasped by the lifting blades 45 and raised up to the highest point of the drum 2.
- the sugar particles begin in a thin veil before the highest point of the lifting blades 45 is reached trickle down, falling freely over the cross-sectional height of the drum 2.
- the discharge end 10 of the drum 2 is supplied with cooling air distributed over the cross section in accordance with the arrow 7, which flows through the free-flowing curtain of sugar.
- the flat and approximately horizontally arranged top 40 of a cooling air box 15 is provided below the drum axis 11 along a secant of the drum cross section.
- the top 40 of the cooling air box 15 is provided with openings and is charged with cooling air according to arrow 7 in FIG. 4 with such volumetric power that a fluidization bed 42 is formed depending on the grain size of the sugar particles on the top 40 of the cooling air box 15 Can form sugar particles. From Figure 5 it can be seen that due to the design and arrangement of the cooling air box 15, the fluidization bed 42 has constant thickness over its entire longitudinal and transverse extent, so that the same flow conditions and thus the same cooling effects are present throughout the bed.
- the fluidization bed 42 is divided in the direction of the axis 11 of the drum 2 by transverse weirs 41 into a plurality of bed sections which are independent of one another. the arrangement is such that the particles from a bed section generally cannot pass over the upper edge 41a of the respective weir 41 into an adjacent bed section.
- Each fluidization bed section is only open upwards and towards the side of the drum circumference indicated by the arrow 51 in FIG. 5, on which the lifting blades 45 execute a descending movement.
- Heat exchangers 50 can be arranged in individual or all sections of the fluidization bed 42, through which a coolant flows and with which the cooling air and the sugar particles can come into direct contact.
- the cooling air is supplied to the cross section of the cooling zone 4 and the cooling air box 15 separately, so that the fluidization bed 42 can be controlled via the cooling air supply to the cooling air box 15 independently of the cooling air effect in the cooling zone 4. Due to the high cooling capacity in the fluidization bed 42, the total cooling air capacity can be adjusted so that there is only a comparatively low air flow rate in the cooling zone 4. For example, be achieved that the cooling air has a speed at the passage into the device 13 for discharging the exhaust air, which is well below 2.5 m / sec. lies. The arrangement is preferably such that the cooling air speed is only in the range of 1.75 m / sec. lies.
