Definitions

  • the invention relates to a tempering machine for lumpy goods, in particular dryer or pasta dryer, with a) a drum, which essentially consists of b) frontal drum elements (shields) and c) extending between these drum elements, arranged side by side at a distance from the drum axis and is enclosed by a wall enclosed chamber elements.
  • a temperature control machine When we are talking about a temperature control machine, it is meant to express that such a machine is of course also suitable for cooling and in general for any type of heat or cold treatment. Therefore, the use of such machines is not limited to pasta, but could also be used for the heat treatment of fruits (e.g. nuts or beans of all kinds) or for mineral, lumpy goods.
  • fruits e.g. nuts or beans of all kinds
  • mineral, lumpy goods e.g. nuts or beans of all kinds
  • Such a temperature control machine is known from FR-A 888 387.
  • the drum of the known temperature control machine has an outer wall lying on the outer circumference, an inner wall lying on the inner circumference and a plurality of dividing walls which radially connect the inner wall to the outer wall and divide the area between the inner wall and the outer wall into individual chamber elements.
  • the outer wall of each chamber element like the inner wall of each, has a tightly screwed sieve.
  • a drying drum with sector-shaped pocket trays is known.
  • the drum consists of a frame that is approximately the shape of a cross section with spoked wheel.
  • sector-shaped pocket trays can be inserted interchangeably into the sector-shaped pockets located between the spokes.
  • the pocket trays are provided with perforated perforated walls and have a flap attached to the front by hinges.
  • This known rack dryer is designed without a conveyor. The dry goods must be introduced through the flap in the front.
  • each chamber element In a drum dryer for pasta which has become known from IT-PS 512 118, the conveying device in each chamber element consists of a type of screw formed by correspondingly shaped walls, which is, however, immovably arranged in the chamber element and only rotates eccentrically around the drum axis with each drum revolution.
  • the result was that General cargo moved under the action of gravity along the screw gears, which brought about a gentle conveying, which avoided the risk of crushing and excessive abrasion.
  • pasta dryers have also become known in which a driven screw is provided within each chamber element. In this case, the chamber element usually had a cylindrical shape.
  • each chamber formed a channel for the dry air, which generally flowed across the drum.
  • the screen wall of the outer and inner circumference of the drum was fixed to the chamber housing. In the case of sticking, access to the interior of the housing was therefore difficult, so that cleaning could hardly be carried out in practice.
  • the invention is based, to develop the generic tempering machine with a view to a stable drum with easier assembly the task.
  • chamber elements of the generic temperature control machine are designed as individually replaceable components which can be detachably connected to the end drum elements (non-destructively).
  • the drum consists of drum elements on the end face and chamber elements which are individually interchangeably fastened in between.
  • the chamber elements preferably have a first screen hole wall on their radially outer jacket wall and a second screen hole wall on their opposite inner jacket wall. Furthermore, the chamber elements for forming free spaces between them preferably have a cross-sectional shape that deviates from a sector shape and is preferably polygonal. Holding and tensioning devices are arranged in these free spaces, by means of which at least the first perforated screen wall can be releasably fixed in a closed position or in an open position. In this way, in particular, a convenient, easy accessibility to the interior of the chamber is created in a simple manner and, at the same time, its cleaning is facilitated.
  • a drum 1 is mounted in a drum housing 2 in a manner not shown.
  • the drum 1 is divided at predetermined, preferably uniform intervals by drum shields 3 (hereinafter also referred to as shields 3).
  • drum shields 3 On the side of the drum housing 2, each of these drum shields is opposite an intermediate wall 4 which closely surrounds the shields 3.
  • the shields 3 can be pushed into the opening 5 of the intermediate wall 4 surrounding it, or the intermediate wall 4 is divided and is only completed after the shield 3 has been inserted.
  • the shields 3 may have a groove and / or a spring on their outer surface which engages in a corresponding groove or shape of the intermediate wall 4, in order to improve the seal between the shields 3 and the intermediate walls 4 to achieve treatment chambers 24 formed.
  • the shields 3 and / or the partition walls 4 are made up of several layers, of which individual layers protrude corresponding to a spring or form a depression.
  • the drum 1 receives a number of box-shaped chamber elements 6 on its circumference.
  • Each chamber element 6 includes a conveyor which can be driven in the manner described at the beginning or can also be operated only passively by the rotation of the drum, but which in any case transports the goods to be treated, generally pasta, at a uniform speed over the length of each chamber element 6.
  • the chamber elements 6 in mutually adjacent drum sections separated by a shield 3 are aligned such that the material to be dried at the end of a chamber element 6 of the (in relation to FIG. 1) rear drum section passes through one of the openings 7 and from there falls into a chamber 6 of the front drum section.
  • the material to be dried then passes through the corresponding chamber element 6 in the front drum section and exits again at the foremost plate 3, with corresponding discharge devices being provided for the dried material.
  • Such devices are known from the prior art and therefore do not need to be explained in detail. It should only be pointed out that it is also known to remove the dried material from the inside of the drum, which is also within the scope of the possibility here.
  • the sieve fabric 8 delimiting the inner circumference of the drum somewhat narrower, so that there is enough space between its edge and the adjacent shield 3 to prevent the dried material from falling down on the underside of each chamber element 6 and on the edge thereof to allow attached outlet opening.
  • the outlet opening can also be arranged in the region of the outer circumference of the drum 1, the dried material falling out being collected below the drum 1.
  • the sieve fabric 8 delimiting the inner circumference of the drum 1 is placed over rods 9 which are each fastened between two shields 3.
  • the inner screen wall consists of a single screen fabric 8 which is common to all chamber elements 6 arranged on the drum 1, a particularly advantageous embodiment is shown for the outer screen wall.
  • Each chamber element 6 is assigned a separate sieve wall 10, which is held taut at its lateral ends by means of inserted rods 11 on the housing of each chamber element 6. How this is done in detail will be explained later with reference to FIGS. 3 to 5.
  • the drum 1 due to its formation with sieve walls on the inner and outer circumference transverse to it
  • the axis is permeable to air, so that a treatment gas, generally warm air, can be blown into a treatment chamber 24 in each case, for example on the underside in accordance with arrow 12, and can be discharged at the top, for example via an exhaust pipe 13. Examples of the routing of the treatment air are explained below with reference to FIG. 2.
  • FIG. 2 and the following figures, parts with the same function are designated with the same reference symbols, parts with a similar function are also identified, but with the addition of a hundred digit. Accordingly, it can be seen from FIG. 2 that the drum housing 2 is jacked up on a frame 14. In order to facilitate access to the interior of each treatment chamber 24 or to the drum 1, the side walls 15 of the drum housing 2 can be opened in the manner indicated by arrows. For this purpose, hinges (not shown) are provided on the top of the drum housing 2. It is also indicated how the material 16 to be dried is circulated in the chamber elements 6 when the drum 1 rotates, and it is understandable that during this circulation the material 16 is transported along the screw flights already mentioned.
  • each treatment chamber 24 has an inlet opening 20 on its front intermediate wall 4 'and an outlet opening 21 on its rear intermediate wall 4. Through these openings 20, 21, a connection can be made with the adjacent treatment chambers, provided these openings 20, 21 are not closed.
  • the flow path for the through-air operation is given by the axis of the tubes 23 and 13 or the openings 20 and 21. This ensures that air is passed through the chamber elements 6 in the upper and lower quarters of the drum 1 in the through-air mode. But in the upper and lower quarters in particular, the screen hole walls 10 of the chamber elements 6 are completely covered by the material 16, so that it is ensured that the air cannot pass the material essentially ineffectively. However, even with a narrow construction of the treatment chamber 24, there is still enough space on the side to allow the through-air to escape.
  • FIG. 3 shows a first embodiment of box-like chamber elements 106 distributed over the drum circumference, which - seen in cross section - have approximately a polygonal shape.
  • the wall section 25 facing the respective adjacent chamber element 106 is kinked and extends in such a way that a radially inward section 26 runs parallel to the corresponding wall of the adjacent chamber element 106. This measure ensures that a negligible thinner Gap remains between adjacent chamber elements 106, and so the air is forced to flow through the inner perforated screen wall 8, to rinse the material to be dried inside each chamber element 106 and ultimately to emerge again on the outer perforated wall 110.
  • the radially outward-lying part 27 of the wall section 25 encloses an angle with the part 26 in such a way that a free space 28 is formed between sections 27 of mutually adjacent chamber elements 106.
  • This free space 28 serves to accommodate a holding device and a tensioning device for each of the screen hole walls 110 assigned to only one chamber element 106.
  • each chamber element 106 can extend in the form of a slot from a central wall 30 to the side wall section 25. This gives the outlet opening 29 a shape that deviates from the rectangular shape. Therefore, in order to feed the dry material to a (in the manner shown) rectangular outlet opening 29, an inclined wall 31, indicated by a broken line, can extend from the side wall section 25 to the outlet opening 29.
  • the inner perforated screen wall 8 may here be placed over cylinder brackets (not shown) defining the inner circumference of the drum 1, so that it has an essentially completely cylindrical surface.
  • the housings of each chamber element 106 are concavely shaped on their side resting against the screen hole wall 8, as can be seen from FIG. 3.
  • the individual chamber elements 106 must be tensioned very strongly against the inner screen hole wall 8 to prevent slitting.
  • the clamping device for the radially outer screen hole wall 110 which will be described below, can simultaneously act as that clamping device which brings about the pressing of the inner screen hole wall 8 against the housing of each chamber element 106.
  • a rectangular frame (see FIG. 1) that extends over the entire housing of the chamber element 106 is provided, which consists of two rods 11, 111 and a spring clip 32 at each end of a chamber element 106 .
  • the chamber element housing can have a small cutout on the upper side, but each drum shield 3 can also be provided with a corresponding lateral groove.
  • the arrangement of spring clips 32 helps to keep the screen fabric forming the screen hole wall 110 taut. Since the chamber elements 106 can be made relatively long in the manner shown in FIG. 1, it may be expedient to also provide additional spring clips 33 between the opposite ends of each chamber element 106, which protrude beyond the screen hole wall 110.
  • Each spring clip 32, 33 can be pivoted about an axis 43 such that it can move from the closed position shown in FIG. 3 by means of the middle chamber element 106 to the open position shown by means of the right-hand chamber element 106.
  • the screen perforated wall 110 may be loose in the manner shown, but depending on the selected deflection of the spring clip 32, it can also be tensioned by its inherent elasticity.
  • a tensioning device which in the simplest case consists of a tension spring 35. If too 3 shows only a single tension spring 35, it is understood that in the majority of applications at least two tension springs 35 must be provided at each end of a chamber element 106, but possibly also in between.
  • Each tension spring 35 engages on an anchoring pin 36 fastened to a drum shield 3 (cf. FIG. 1) and is hooked on to the other end on the rod 11 forming the holding device together with the rod 111.
  • This construction ensures, on the one hand, that the outer perforated screen wall 110 is always tensioned and is in contact with the housing of each chamber element 106 without any gap formation. In addition, this construction ensures that the screen hole wall 110 can reach its open position by simply unclamping the tensioning device 35 and so that each individual chamber element 106 is easily accessible for cleaning purposes. Furthermore, a single chamber 106 can also be easily removed from the drum circumference in this way, so as to clean the inner screen hole wall 8.
  • the new insertion of an individual chamber element 106 is additionally supported by the polygonal shape shown, because the approximately radially running wall sections 26 of the adjacent chamber elements act as guide and orientation surfaces. It also has a relief if the anchoring parts 34, 36 are arranged along a radial line 37.
  • FIG. 4 shows how a screen fabric 310 can be arranged on a chamber element 6, for example as an inner screen hole wall, by tension springs 35 acting on a reinforced fabric edge 51.
  • the inner screen hole wall does not necessarily have to be formed by a screen fabric that is common to all chamber elements, but that this inner wall can, if appropriate, be designed exactly as has been described previously with reference to the outer screen hole wall 10 and will be described below will be.
  • at least the outer perforated screen wall 10 is preferably divided into a plurality of angular sections over the outer circumference of the drum 1, a separate perforated screen wall preferably being assigned to each chamber element.
  • the screen fabric 310 is first suspended in the springs 35.
  • the chamber element 6 is then inserted between two stops 52 attached to the shield. If necessary, the stops 52 can have funnel-shaped bare cones for more precise orientation of the chamber 6.
  • the outer sieve 10 is then placed over it and pulled down with the aid of quick-release fasteners 53 which are suspended in the holding rods 11 and anchored on the shield 3. In this case, the quick-release fasteners 53 are pulled against the action of the tension springs 35, which tension themselves more strongly until counter-stops 54 provided on the chamber element housing abut against the stops 52.
  • the tension springs 35 interact with the tension locks 53 to form a common tensioning device for both screen hole walls 10, 310, the stops 52, 54 acting as orientation devices ensuring that the Inlet and outlet openings (cf. the opening 29 in FIG. 1) are exactly aligned with the openings 7 of the shields 3.
  • the funnel surfaces already mentioned on the stops 52 can contribute to the lateral alignment, just as the stops 52 are arranged as closely as possible on the side wall sections 225 of the chamber element housing.
  • the chamber element 6 is shown in the embodiment according to FIG. 4 in the open state and has walls consisting of five surface sections in a known manner. While the lower surface section 55 extends over both chamber halves separated by the central wall 30 essentially perpendicular to the longitudinal axis of the chamber element 6 (see FIG. 6), the darker shaded section 56 adjoining on the left extends from there from below and further inside (with reference to the plane of the drawing) upwards and outwards until, after a pitch of the screw thus formed, a wall 57 adjoins the wall section 55 in a parallel plane.
  • an obliquely inward, lightly hatched wall section 58 (cf. FIG. 6), to which a wall section 50 adjoins this at a distance from the wall section 57 at a pitch.
  • the top and bottom of the housing of the chamber element 6 is expediently rounded in order to apply a more uniform tension to the respective screen fabric 10 or 310. This rounding can take place in accordance with an arc of a circle, but the best uniformity results when training along a parabolic arc.
  • FIG. 5 illustrates further possible configurations using chamber elements 306, 406 and 506, of which the chamber element 406 in side view together with a drum shield 3 from FIG. 6 can be seen.
  • chamber elements 306, 406 and 506 of which the chamber element 406 in side view together with a drum shield 3 from FIG. 6 can be seen.
  • 5 differently designed chamber elements 306 to 506 are shown to illustrate different embodiments, also to illustrate that, if necessary, differently designed chamber elements can also be used side by side in a drum.
  • the chamber element 306 has a passive, i.e. only by the rotation of the drum acting conveyor device of the type known from IT-PS 427 072 en.
  • the chamber element is divided by a number of partitions 60, which are surmounted by inclined, channel-like conveyor chutes 61.
  • the material to be dried slides down a conveyor trough 61 and, at the next half turn of the drum, reaches the upper region, from where it slides into the next chamber element via the adjacent conveyor trough.
  • the housing of the chamber element 306 can be provided with handles 62, on which schematically indicated tensioning fasteners 53 (see FIG. 4) designed in a known manner act.
  • the chamber element 306 is brought into its aligned position with the chamber elements on the other side of the respective shield, stops 154 again corresponding to the stops 54 of FIG. 4 (only one stop 154 is shown) can be provided.
  • the stop 154 is shown in an exploded view in FIG. 5 because it also fulfills another function.
  • a tension spring 35 for engagement with a holding rod 11 of the outer screen hole wall 10 can namely be anchored to it.
  • the support rod 11 may be hit at the other end, or it is on the right side (refer to FIG. 5), the support rod 11 is combined with the handle 62, whereby it also performs a double function there for the attack of the tension lock 53 there, but on the other hand has the consequence that the sieve 10 can only be detached from the chamber element 106 after the rod has been removed from its holder on the handle 62.
  • This example shows that the respective screen hole wall does not necessarily have to be attached to a holding device of the shield, but that the holding device can also be provided on the chamber element itself.
  • the stop 154 is assigned a corresponding counter-stop (not shown).
  • a possible embodiment of the funnel-shaped side flanks of such a counter-stop 152 is shown on the chamber element 406. However, in this embodiment it acts only as a centering aid because a stationary counter-stop 252 is welded to the shield 3 in the manner shown in FIG. 6.
  • This counter stop 252 interacts with a stop 254 which is fixedly connected to the chamber element housing and is provided with an angled plate 63.
  • This plate 63 has a slot-shaped opening 64, in which a pawl nose 65 engages.
  • the pawl nose 65 is formed on a spring arm 66 which is attached to the counter stop 252.
  • the lower surface 67 of the nose 65 is slightly beveled, so that manufacturing tolerances are compensated for and this surface 67 is in any case in contact with the lower edge of the opening 64 (cf. FIG. 5).
  • the chamber element 406 is fixed in a position in which the two stops 252, 254 abut one another.
  • the latch nose 65 which forms a snap lock, only needs to be pulled out of the opening 64 of the plate 63.
  • the pawl 65 can be assigned a locking device in order to hold it in the open position against the action of its spring arm 66.
  • FIG. 6 is only a particularly advantageous example, in which the individual chamber elements 6 or 406 can be loosened or attached quickly to the associated drum shields 3 due to the quick coupling device shown.
  • the centering device shown With the aid of the centering device shown, not only a correct fit can be ensured, but in the end also a relatively rigid construction, in which the chamber elements 6 form the stiffening ribs between the shields 3.
  • another type of releasable connection for example a screw connection, may be preferred.
  • no or only a weaker supporting structure is required.
  • this modular arrangement not only makes assembly easier, but it is also easy to expand for each machine, so that production and warehousing are also simplified and cheaper.
  • the holding device and the tensioning device for the screen hole wall 10 are not shown in detail and can be designed in accordance with one of the previously described embodiments.
  • the chamber elements 506 show how the sealing effect in the region of the mutually parallel and approximately radially extending side wall sections 126 can be improved by designing it as a type of labyrinth seal.

  • the bulges 68 and the depressions 69 (which do not necessarily have to be triangular, but can also have a different shape, for example a wave shape) represent reinforcing beads for the side wall sections 126, 226, so that these wall sections can optionally be formed from weaker material. This not only saves costs, but also reduces the overall weight of the machine. In order not to jeopardize the removal of individual chamber elements 506 if the toothed sections 126, 226 are too strongly interlocked, these beads 68, 69, which preferably have a rounded shape, should have an opening angle ⁇ which is greater than 45 ° and is, for example, approximately 60 °.
