Definitions

  • This invention relates to flowing or impelling treatment of substances, especially in heat transference operations.
  • This invention has utility as a centrifugal evaporator more particularly for film treatment of milk.
  • Fig. 1 is a side elevation with parts broken away of an embodiment of the invention in a centrifugal evaporator
  • Fig. 2 is an end view with parts broken away;
  • Fig. 8 is an enlarged detail section of the apparatus of Fig. 1, at the discharge.
  • Shaft 4 is shown as provided with a hub 13 carrying arms 14 carrying ⁇ pivoted blades wall.
  • the substance to he treated, as a flowing material, may be considered as milk,
  • the speed of operation is such that this nate rial is at once thrown vas a thin sheet or film about the interior of the wall 7 blades or impellers 15 seem 'to have a fanningl action as well as a dispersing action and the material is free to flow during this high speed of revolution of the impellers 15, and this flow is toward the remote or opposite head 6 of the apparatus from which it may escape by elongated opening 23 flush with the surface 7 into duct ⁇ for pipe 24. Accordingly, there is no head resisting discharge of the treated material.
  • a vessel three feet in diameter and three feet long may readily handle as low a volume as two quarts, or less, in the machine.
  • the speed of operation as indicated is gaged to urge the materal to change its position as to the wall 7 at such a. rate that the capacity for delivering heat by this copper or good conductor wall or partition may be at a maximum.
  • the capacity per unit of area for this smooth portion of the partition is thus directly mechanically controlled.
  • the conductivity of this partition having the surfaces 7, 8, is very considerable when the material is of copper.
  • escaping vapors may pass through the open end V5 by way of sha-ft 25 to be 'thrown ofi1 by the stack height or by fan, as may be desirable.
  • the proportion of Water removed may be suoli as to condense the milk from three volume to one volume, or eren less.
  • a heat transference apparatus embodyingl a horizontal cylindrical chamber having a head, and an intake opening of slot form in the head spaced from the cylindrical portion of the chamber to interpose resistance against back flow thereinto, a second head, and an outlet in the second head flush with the cylindrical portion of the chamber for ready discharge flow therefrom.
  • a heat transference apparatus en'ibodying a cylindrical chamber, means for impelling' substance therein continuously as a tubular layer, and a steam jacket for the chainber, said. chamber havingl a sheet metal wall corrugated on the jacket side thereof only.
