Definitions

  • the invention relates to a mixer dryer according to the preamble of claim 1.
  • a mixer dryer according to the preamble of claim 1.
  • liquid to free-flowing and even pasty products can be mixed.
  • thermal exchange surfaces In order to achieve a better yield and better quality with even shorter dwell times, especially in the treatment of pasty and baking products, especially in continuous processes, the thermal exchange surfaces must be kept free by cleaning. In addition, solidifying material has to be continuously comminuted and mixed thoroughly if the force is not too great. The mixing and shear organs themselves should be sharp and should not give rise to bridges and toruses, so that the mass transfer is maintained in continuous processes.
  • the invention has for its object to provide a novel design of the mixing and cutting elements of such mixers and kneaders, which enable continuous processing of the products and ensure a uniform material transport.
  • a mixer designed according to the features of claim 1 is particularly suitable for processing liquid to free-flowing products.
  • a further embodiment of the invention provides for the processing of toothpaste-like and possibly caking products that a distance is provided between the coulters of a row of disk segments and the next subsequent row of disk segments, in the area of which scraping jaws fastened to the housing shell are provided, Scraper hooks and / or mixing scrapers are located, which scrape off the surrounding disc segments and free them from adhering material.
  • the invention provides that there are crust breakers in the gaps radially between the disc segments, which are used to clean the scraping hooks and mixing scrapers attached to the housing shell. These crust spreaders can be distributed evenly over the length of the mixer or can be arranged only in particularly endangered areas.
  • Fig. 1 a section along the line A-A of Fig. 4;
  • Fig. 2 a cross section without crust breakers 7 and 8 along the line A-A
  • Fig. 1; 4 shows a cross section with crust breakers 7 and 8 along the line C-C of FIG. 1;
  • Fig. 5 a detail along the line B-B of Fig.;
  • Fig. 6 a detail along the line C-C of Fig. 4;
  • 7 a representation in a development of the mixing and cutting elements with a perspective view of the same;
  • Fig. 8 a partial section of a development of the disc segments and Seharenr
  • Fig. 9 a partial section of a development of other disc segments and
  • FIG. 10 a partial section of a processing of further disk segments
  • a mixer dryer consists of a heatable and / or coolable housing 1, which rests on four feet 22 and is provided with different nozzles 23 for the entry and one or more nozzles 24 for the discharge of the vapors. Furthermore, nozzles 30 for cleaning and emptying and after a baffle plate 12 displacers for the discharge 25 are provided in the bottom of the housing. This can be seen from FIGS. 1, 2 and 3.
  • an agitator shaft 4 is rotatably mounted on shaft journals 14 and 18 and sealed with stuffing boxes 15 and IS against the product space.
  • the agitator shaft 4, which can be heated via a rotary sealing head 26, is driven by an electric motor (not shown here) via a V-belt drive 27 and a gear 28.
  • the agitator shaft carries, at certain intervals, radially encircling vertical rows of rotated and heatable disk segments 5, along the outer diameter of which blades 6 are fastened.
  • All mixing and cutting elements are provided with sharp-edged blades for the constant self-cleaning of the thermal exchange surfaces from the caking and crusting product, as can be seen in FIG. 12.
  • the circumferential coulters 6 clean the inside of the cylindrical housing 1 except for the ring zones of the scraping hooks 2 and mixer bars 3 projecting into the product space, which clean the circumferential disc segments 5, and also ensure constant comminution and mixing of the solidifying material. This can be seen in FIGS. 1, 2, 4 and 12.
  • the end face 16 is cleaned by the end scrapers 10 according to FIGS. 1 and 3 shown in FIGS. 1 and 2.
  • scrapers 2 and mixing scraper 3 have only the number of legs that are required for the surfaces to be cleaned. In the area of the attack surfaces, like the shares 6, they are of small cross-section and have sharp cutting edges, so that they give no reason for bridges and torus formation.
  • the backward rotation of the disk segments 5, ie the clearance angle a to the housing wall, is likewise provided on the coulters 6 fastened thereon. In order to the product passing through the gap between the coulters 6 and the housing wall is not rolled on.
  • FIG. 13 is used for mixing liquid to giant-shaped products in which no caking or crusting is to be expected. For this reason, only disc segments with coulters attached to them are provided, and these can be designed as described above.

Abstract

Séchoir malaxeur permettant de traiter mécaniquement et thermiquement, surtout en continu, une plus grande quantité de produits liquides à coulants ainsi que visqueux, pâteux et collants dans l'industrie chimique et d'autres industries. Grâce à la coopération des segments de disques (5) à dépouilles disposés sur l'arbre d'agitation (4), aux lames (6) fixées d'un côté sur lesdits segments, ainsi que grâce aux broyeurs de croûte (7 et 8) et aux crochets racleurs (2) et aux racloirs malaxeurs (3) fixés dans le logement (1), on empêche les blocages, pontages et formations toroïdales. On y parvient grâce à cette conception d'un type nouveau, aux couteaux tranchants, aux faibles sections transversales des surfaces d'attaques des organes malaxeurs et racleurs et grâce à l'utilisation facultative de broyeurs de croûte, lesquels entretiennent l'action des organes racleurs. Un nettoyage réciproque des surfaces d'échange thermique ainsi qu'un broyage et un malaxage intensifs de la matière se durcissant permettent d'accroître le débit évaporatif et garantissent un transport en continu de la matière.
