Definitions

  • the invention relates to devices according to the preamble of claim 1.
  • the heat treatment is of particular importance.
  • product temperatures of at least 85 ° C and about a residence time of at least four minutes are provided.
  • Hot air treatments are also known. In common heat treatments, there is a risk that the temperature distribution is not uniform or not homogeneous. Hot air hot air treatments often produce short circuit flow channels with high air flow and heat exchange. In addition, at high flow velocities undesirable separation occurs with regard to the particle sizes and the entrainment of an undesirably high proportion of product.
  • the cooling should efficiently ensure a uniform final temperature and final moisture. It has now been shown that high cooling air throughputs, with extensive loosening of the product, allow an intensive exchange of heat and moisture, but at the same time lead to an undesirable separation in terms of particle sizes and carrying an undesirably high proportion of product. The portion entrained in the cooling air must be separated from the cooling air by means of large-scale separation devices. It has been shown that valuable fine-grained additives are also discharged. When cooling air is passed through larger layers of bulk material, short-circuit flow channels with a high air throughput and a low heat exchange often occur.
  • a mixer which comprises a rotatably arranged drum with a partially perforated jacket wall in a housing.
  • the product passes in the region of a first end face in the drum and is moved for example by means of a screw attached to the inside of the jacket wall due to the rotational movement of the drum against the second end face, where an outlet opening is provided.
  • An air guiding device comprises a feed device on the housing and a discharge device from the drum, so that the process air passes through the perforated region of the jacket wall and the bulk material adjacent thereto into the interior of the drum and via the discharge device from the drum.
  • the bulk material is fluidized by the process air and mixed due to the rotation of the drum to avoid uneven treatment due to the formation of dead zones.
  • a device with a rotatable drum and a fluidization bed is known.
  • the fluidization bed is formed by an air box with a perforated surface, wherein the air box and thus the fluidization bed extends in the lower portion of the drum interior in the direction of the axis of rotation over a portion of the drum.
  • the drum In the area with the air box, the drum on its inside a ring of lifting blades, so that bulk material is carried by the lower drum area, which trickles as the blades rise against the upper drum area from the lifting blades on the fluidizing bed.
  • the trickling bulk material is both from air which is conveyed along the drum axis through the drum and flows through air from the air box.
  • the bulk material falling onto the air box or onto the fluidization bed must flow transversely to the drum axis beyond the edge of the fluidization bed to the lower drum area, where it is detected by the lifting blades. At least in For a portion of the drum to be able to remove the process air upwards, the drum wall must be perforated in this area. It is now very difficult to design the drum, the air box and the drives for the process air in the drum and in the air shaft so that a bulk layer with constant thickness and in the direction of the drum axis a desired throughput of bulk material is ensured on the entire fluidization. The design varies greatly correspond to the bulk material to be treated, so that no versatile standard device can be provided.
  • the layer thickness on the fluidization bed can vary greatly, in particular undulating, which leads to greatly differently treated subsets of the bulk material.
  • large flow velocities must be selected, which leads to undesirable separation in terms of particle sizes and to carry an undesirably high proportion of product.
  • the openings of the fluidizing area become blocked with bulk material.
  • a disadvantage of rotary drum devices is that only a small portion of the drum volume is filled with bulk material during operation. It is essentially a bulk kidney that occupies a maximum of 10 to 15% of the drum volume. Also over the fluidization areas, the filling level is severely limited, which has a negative effect on the achievable filling quantity. Due to this small capacity and because rotating drums also need to be rebuilt or shut off for safety reasons, the space required in relation to the receiving volume and thus the achievable throughput is undesirably large.
  • DE 149 590 and DE 323 462 containers are known in which a driver cage is rotatably disposed about the container axis. According to DE 149 590 feeds and top discharges are arranged to carry out steam at the bottom of the container. The movement and thus the treatment of individual particles of the bulk material is very different.
  • the object of the invention is now to find a simple, versatile and efficient device for treating bulk material with process gas.
  • a rotating drum in the interior of which the bulk material is received, limits the possible uses of the device.
  • supplying and discharging process air into or out of a rotating drum tight connection must be provided from the rotating drum to the non-co-rotating, stationary air guide parts, which is associated with a great effort.
  • a portion of the process air can not be passed through the bulk material.
  • the wall of a rotating drum can be connected only with additional effort to a cooling or heating circuit. If a solid or a non-rotating container is used, it can be formed with little effort with a heating or cooling jacket and thus also give contact heat to the bulk material or absorb heat from this.
  • a container As a solid container, a container is referred to, which is not rotated and thus always remains in the same position. With a solid container, no measures are necessary to prevent operators from contacting rotating parts. Air guide parts can easily be connected tightly to the non-rotating container.
  • a driver cage In order to be able to convey the bulk material in the axial and / or circumferential direction of a cylindrical container having a substantially horizontally extending container axis, a driver cage is rotatably arranged in the container about the container axis, which makes carrier elements movable along the container inner wall.
  • the driver cage comprises at least one screw element and optionally at least one substantially parallel to the drum axis extending fin element.
  • the design of the worm and / or the lamellar elements allows desired bulk material movements in the direction of the container axis and to achieve in the circumferential direction.
  • the container axis is arranged slightly inclined, so that the bulk material movement is excited or supported in the axial direction by gravity.
  • the entry opening can be directed downwards and can be a large opening, so that the obstruction occurring in fluidizing areas can be excluded.
  • the supply opening is directed downwards, it is formed, for example, on a supply device arranged in the interior of the container and of the carrier cage.
  • the lamellar or possibly the screw elements can take the bulk material in the circumferential direction up to an upper portion of the container interior, they are optionally formed scoop-shaped.
  • the lamellar elements cooperate in the rise area with an inner guide surface, so that a conveying region is formed between the container inner wall and the guide surface, in which the worm and / or lamella elements move.
  • the bulk material is thus pushed in the direction of movement of the screw and / or lamellar elements in front of these elements through the conveyor area.
  • the bulk material conveyed in the circumferential direction falls in a veil from the upper end of the guide surface through the container against its lower region.
  • they In a solution with paddle-shaped lamellar elements, they must be formed so that the bulk material is emptied in a predetermined peripheral region of the lamellar elements to form a veil.
  • the inventive solution thus comprises a solid container with a cylindrical shell wall.
  • the container axis is substantially horizontal, or inclined at a small angle to the horizontal.
  • a driver cage is rotatably disposed within the container about the container axis and includes follower elements that move as it rotates along the container interior wall.
  • the driver cage comprises as a driver element at least one screw element and / or at least one substantially parallel to the drum axis extending fin element.

  • the discharge area is formed by the upper end region of the guide surface.
  • the guide surface is connected to the supply device for the process air, wherein the feed opening connects, for example, to the lower edge of the guide surface.
  • the guide surface and in particular the associated feed device from the container in the axial direction is arranged to be pulled out.
  • the veil-like falling bulk material is absorbed in the lower part of the container. It forms in a collection area a bulk layer with an upper level surface.
  • the bulk material is set in motion by the driver elements.
  • the driver elements comprise at least one preferably continuous screw or helix and a guide surface is provided, then a controlled throughput of the bulk material can be ensured by the container.
  • the thickness of the conveyor area between the container inner wall and the guide surface is determined.
  • the thread pitch determines the achievable throughput per turn.
  • the throughput per revolution can be converted by the multiplication with the speed into a throughput per time.
  • the ratio of vessel fill to throughput per time provides the average residence time. For a given treatment time can be determined according to the configuration of the device an appropriate speed.
  • a continuous screw ensures, in addition to the controlled throughput, that particles in the same volume range are essentially always guided together during feed in the screw.
  • This controlled feed helps to achieve a narrow treatment spectrum for all particles. Accordingly, a homogeneous treatment of the bulk material can be achieved and the risk for insufficiently treated particles can be greatly reduced.
  • the mean residence time can be selected directly according to the desired treatment time. Because the residence time does not have to be unnecessarily large, a high throughput can be achieved.

With the process air moisture can be removed from the bulk material, so that even with the entry of large amounts of steam, the moisture content of the bulk material during discharge is in a desired range.
  • the device mechanically achieves a bulk veil with loosened bulk material, or with particles that are surrounded by free spaces.
  • process air can enter into intensive heat exchange contact with the bulk material.
