Definitions

  • the invention relates to a method of injecting and finely distributing a liquid in pulverulent or granular materials for various purposes.
  • a reaction may be triggered by the addition of a liquid, or fine pulverulent materials may be rendered dust-free or granular.
  • it may be desired to add to the solid materials an aromatic liquid or a dye solution.
  • the novel method which includes the following steps: imparting a rotary motion prevent the formation of lumps.
  • the particles wetted by the liquid are separated by centrifiugal force and are guided downward along the wall of the conical treating chamber to an outlet, while the drier particles, drawn into the planetary secondary stream, are introduced into the circular motion of the inflowing sheet of wetted pulverulent materials to continuously commingle therewith and then separate after attaining a certain saturation.
  • the circulating main stream of the hollow conical ring prevents a deposition in the treating chamber of the particles saturated with liquid and effects a continuous cleaning of the internal walls. It has been found that even in case of a 40% proportion of fat, a caking or deposition did not take place.
  • a further important advantage resides in that by means of the afore-described novel method the pulverulent materials are treated in a protective manner so that even larger delicate pieces that may be present in the pulverulent material (such as mushrooms or noodles in soup mixtures) are not damaged.
  • the apparatus for performing the afore noted method comprises substantially a downwardly narrowing conical treating chamber provided in its upper portion with an axially aligned inlet and in its lower portion with an axianlly aligned outlet, a horizontal distributor disc disposed in said chamber and provided on its underside with a plurality of radial vanes carrying at their lower edge portion an axially aligned-frustoconical shell.
  • the disc is keyed to a vertical shaft extending into, the treating chamber and rotated by motor means disposed externally thereof.
  • FIG. 1 is a schematic sectional elevational view of the preferred embodiment
  • FIG. 2 is a perspective view of one part of the preferred embodiment.
  • the apparatus shown therein comprises a downwardly narrow-ing conical treating chamber 1 having at its upper portion a central inlet tube 2 and at its lower end a central outlet 3.
  • the top of the chamber 1 is covered by a conical lid 1a in which there is disposed in a horizontal circular array a plurality of spaced spraying nozzles 11 which communicate with a circumferentially arranged liquid conduit 12 through branch conduits 14 each provided with a manually operable valve 13.
  • Within the treating chamber 1 there is vertically disposed, in axial alignment with inlet 2 and outlet 3, a shaft 7 extending through the inlet tube 2 and driven by motor 6 through transmission elements 5.
  • a mixer generally indicated at 15 formed of a horizontal distributor disc 4 carrying on its upper face a concentric conical distributor shute 4a, a plurality of vertical vanes 8 radially affixed to the underside of disc 4 and a frusto-conical shell 8a secured to and surrounding the vanes 8 in a shroud-like manner.
  • the space immediately under the distributor disc 4 is partitioned by vanes 8 and is delimited by shell 8a leaving for each space between two adjacent vanes a radial opening 8b and an axial opening 80.
  • a plurality of radial heaters 10 To that portion of the shaft 7 which extends through the inlet tube 2, there are secured a plurality of radial heaters 10.
  • the dry material is introduced into the inlet tube 2 in equal quantities by means of a feeding device 9.
  • the heaters 10 cause disintegration of any agglomeration of material.
  • the loose material is evenly distributed on the rotating distributor disc 4 by means of conical shute 4a in such a manner that there is formed a coherent sheet of material which is sprayed in the region of its greatest circumferential velocity by means of spray nozzles 11, emitting liquid in a direction substantially normal to the motion of the particles.
  • spray nozzles 11 emitting liquid in a direction substantially normal to the motion of the particles.
  • vanes cause the partices to circulate about the longitudinal axis of chamber 1 in a main stream having the shape of a hollow conical ring.
  • the lighter, drier particles are drawn into a secondary stream travelling about the conical shell 8a, as indicated by arrows A, into and out of the spaces defined by adjacent vanes 8.
  • said secondary stream orbits in a planetary manner about the longitudinal axis of treating chamber 1.
  • the particles become saturated with liquid due to the mixing effect of the above-described dual whirl, they travel downwardly along the conical wall of chamber 1 and eventually leave through outlet 3.
  • EXAMPLE 1 For making soup products, a pulverulent food mixture was introduced through inlet 2 and was uniformly fed to the distributor disc 4. The material was sprayed through the nozzles 11 with a liquid consisting of various fats. It was found that even at slow rotational speeds (which was necessary for the protective handling of large ingredients such as muchrooms, noodles, etc.) and fat proportions of 20-30%, a very good mixture of the liquid and the pulverulent dry material was achieved.
  • EXAMPLE 2 20% moist potato starch was introduced into the treating chamber 1 and was sprayed through spray nozzle 11 with a dye solution. It was found that the obtained product was homogenously mixed and had a highly uniform coloring.
  • the novel apparatus may be advantageously used as a premixer.
  • the premixture obtained by the novel method may be then added to other dry materials in an adjoining air mixer.
  • the novel apparatus is connected upstream of the inlet of the batch mixer or another continuously operating mixer.
  • the thorough mixture obtained from the novel apparatus is commingled with additional dry components which directly mix only poorly or not at all with liquids.
  • a method of mixing loose dry material with a liquid comprising the following steps:
  • a mixer rotatably disposed in said treating chamber and including (1) a horizontally disposed distributor disc, the upper face of which being adapted to receive loose dry material introduced through said inlet,
  • said means for rotating said mixer includes a shaft disposed axially in said chamber and extending outwardly thereof into said inlet, a plurality of beater elements keyed to said shaft in said inlet.
  • An apparatus as defined in claim 3 including a liquid conduit surrounding said circular array of said spray nozzles externally of said chamber, branch conduits associated with each of said nozzles to connect them individually with said liquid conduit, and a manually operable valve disposed in each of said branch conduits.
