Definitions

  • the invention relates to a tempering machine for lumpy goods, in particular to a pasta dryer, with a circumference having a predetermined number of chambers with conveyors for the material to be treated, the chambers being enclosed by a wall, two sections of which lie opposite one another Walls of adjacent chambers facing and two further sections are assigned to the outer and an inner circumference of the drum and at least the latter wall sections have screen hole walls through which a gas flow can be passed in continuous operation with the help of at least one flow generator.
  • a pasta dryer of this type is known from IT-A-512 118.
  • IT-A-512 118 A pasta dryer of this type is known from IT-A-512 118.
  • a temperature control machine it is intended to express that such a machine is of course also suitable for cooling and in general for any type of heat or cold treatment.
  • the use of such machines is therefore not limited to pasta, but can also be used for the heat treatment of fruits (such as nuts or beans of all kinds) or for mineral, lumpy goods.
  • 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.
  • the drum is housed in a treatment chamber in which, in addition to the devices for continuous operation, at least one flow generator for the circulating operation of the gas is arranged such that the flow at least once through the Well-covered screen hole wall of a part that can be passed through chambers arranged around the circumference of the drum.
  • the measure according to the invention ensures that the gas supplied in the continuous operation (generally air, but possibly also steam or an inert or treatment gas) does not simply flow through and remains partially unused, but is additionally conducted around in the treatment chamber. Due to the rotation of the drum, only a part of the chambers will have a screen hole wall completely covered by the material. This gives the possibility that the gas being circulated flows through at the point of least resistance, namely where the material only partially covers the screen hole wall and also leaves an essentially free channel open. Therefore, according to the invention, the flow generator is arranged in such a way that the flow is led straight through those chambers whose screen hole walls are completely covered by the material. This can be done in different ways, for example by close to it Chambers is arranged across the chamber sucking or pushing blower, in the case of an axial blower whose axis should be aligned approximately in the radial direction to the drum.
  • the gas supplied in the continuous operation generally air, but possibly also steam or an inert or treatment gas
  • the flow generator for the circulating air is designed as a fan with a rotation axis running approximately parallel to the tangent to the drum.
  • a particularly favorable gas distribution can be achieved in that the flow generator is arranged at an angle with respect to a cross section through the drum, for example in the range from 40 ° to 45 ° to the direction of circulation of the gas, and again, preferably, together with another such Flow generator should be on a plane running through the drum axis. This ensures that continuous operation and circulating operation do not interfere with each other, on the contrary, the flow circuits even complement each other, which means an even better utilization of the supplied gas and an even higher efficiency.
  • At least one guide surface is assigned to the flow generator, specifically on its side facing the chambers filled with the material covering the screen hole wall, for the forced passage of the gas conducted in circulation mode.
  • a guide surface can be arranged on the opposite side, but if the above-mentioned second flow generator is present, then its guide surface on the side facing the above-mentioned chambers can expediently also have the rear side of the guide surface for the other flow generator on the so Form the filled side on the opposite side.
  • Fig. 1 shows a drum 1 in a drum housing 2, in which it is mounted in a manner (not shown).
  • the drum housing 2 is jacked up on a frame 14.
  • the side walls 15 of the drum housing 2 can be opened in a manner indicated by arrows.
  • hinges are provided on the top of the drum housing 2.
  • the material to be dried 16 to be treated is circulated in chambers 6 when the drum 1 rotates. It is understandable that with this circulation the material to be dried 16 is transported along specially provided screw flights (not shown in FIG. 1) in the longitudinal direction of the chambers.
  • the drum 1 is divided over its length at predetermined intervals by drum shields 3.
  • drum shields 3 On the side of the housing 2, each of these drum shields is opposite an intermediate wall 4 which tightly surrounds the shields 3, the respective shield 3 being able to be pushed into the opening of the intermediate wall 4 surrounding it during assembly.
  • the chambers 6 are box-shaped and arranged around the circumference of the drum 1.
  • a conveyor device In each chamber a conveyor device is provided, along which, as already mentioned, the goods to be treated, generally pasta, can be transported at a uniform speed.
  • the inner circumference of the drum 1 is delimited by a sieve fabric 8 which is placed over rods 9 which are each fastened between two shields 3. While in the embodiment shown the inner sieve wall consists of a single sieve fabric 8 which is common to all the chambers 6 arranged on the drum 1, a separate sieve wall 10 is assigned to each chamber 6 with respect to the outer sieve wall is held taut at its lateral ends with the help of inserted rods 11 on the chamber housing of each chamber 6.
  • the drum 1 is permeable to air transversely to its axis due to its design with sieve walls on the inner and outer circumference, so that a treatment gas, generally warm air, for example, is blown into a chamber at the bottom and at the top, for example via a discharge pipe 13 can be discharged.
  • a treatment gas generally warm air, for example
  • each unit consisting of a radiator 17 and a blower 18.
  • the air contained in each chamber is not circulated in accordance with the arrows 19 and is thereby heated by the heating device 17.
  • the treatment chamber has an inlet opening 20 on its front intermediate wall 4 'and an outlet opening 21 on its rear intermediate wall 4.
  • a connection to the adjacent chambers 6 can be established through these openings 20, 21, as long as the openings 20, 21 are not closed, as is the case this will be described later with reference to another exemplary embodiment according to FIG. 2.
  • a connection can also be made to the non-adjacent treatment chambers, the heated air being able to be conducted via pipes 13 and 23, respectively.
  • a treatment is carried out according to the countercurrent principle, the air laden with moisture being sent to the material to be dried.
  • all openings can also be closed, so that each treatment chamber 24 can have a separate and independent climate setting.
  • 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 precisely in the upper and lower quarters, the screen hole walls 10 are the Chamber elements 6 completely covered by the material, 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.
  • the fans 18 are arranged as circulating air fans and are angularly offset from the vertical 82 so that the circulating air flow does not hinder the vertical through-air flow.
  • the arrows 19 show, there is even a trouble-free circuit, the air being driven through the blowers 18 in accordance with the arrows 19 through the chamber elements 6 in the upper and lower quarters in the circulating air mode, whereas they move laterally where the sieves of the chambers 6 are not completely covered by the good 16, can pass the good and therefore it dries less intensely.
  • the arrangement of the two fans 18 shown on an incline to the vertical 82 (direction of flow of the through-air), e.g. at a 45 ° inclined plane 83 extending through the drum axis ensures that the through air also influences the circulating air circuit by directing the circulating air against the lower and upper chamber elements 6. It is advantageous if guide surfaces 80 are also provided for the forced guidance of the circulating air, which make it impossible to evade the circulating air and forces it through the upper and lower chamber elements 6.
  • the angle between the planes 82 and 83 is designated d in FIG. 2.
  • each of the treatment chambers 24, 124, 224 is provided with a separate unit 17, 18 for heating and distributing the air, but optionally also for treatment steam (for peeling bean fruits such as soybeans, etc.).
  • the drum 1 is driven via its shaft 71 with the aid of a motor 72, but the drive could also take place via circumferential rings of the drum.
  • the material to be treated can be fed to the individual openings in the shields 3 via a channel 73 and a similar channel, not shown, can be provided on the opposite side of the drum 1.
  • both openings 20, 21 can be partitioned off with the aid of a slide 74 or 75.
  • a flap 76 By opening the slide 74 and flipping a flap 76 into its position indicated by dash-dotted lines in FIG. 2, a connection is created between the treatment chambers 24 and 124, so that both chambers can be operated, for example, with circulating air.
  • only one of the two fans of these chambers needs to be put into operation, or one fan 18 can suck the air out of the associated chamber and the other one can blow it in.
  • the directions of rotation of these fans are therefore expediently switchable for different operating modes.
  • a flap 77 it is therefore also possible for a flap 77 to be in a central position between the one with full lines and the one with dashed lines tured lines are brought position, so that in addition to the circulating air, a certain amount of fresh air or another treatment gas, such as steam, is supplied.
  • a certain amount of fresh air or another treatment gas, such as steam is supplied.
  • fresh air can be drawn in continuously for the treatment chamber 24, which, for example when the slide valve 74 is open and the position of the flap 76 shown in full lines, is either supplied to the treatment chamber 224 via the pipe 13 or not shown Way can be blown off.
  • the diagram according to FIG. 2 likewise shows that any variations in the treatment climates in the treatment chambers 24, 124, 224 are possible by means of different pipe connections and / or flap or slide positions.
  • the treatment chamber 24 can be provided for a powerful heat treatment, the treatment chamber 124 for the after-treatment and the treatment chamber 224 for cooling.
  • Each chamber can be provided with a suction and a discharge opening for through-air operation.
  • the chamber 24 can also be provided for gentle predrying and only the chamber 124 for a subsequent treatment process with air at a higher temperature.
  • more than three chambers or only two chambers may also be arranged.
