  • a ring 11 In about the height of the level of the diffusing liquid in the vessel 2 is arranged a ring 11, forming an annular oharnber whose inner wall formed by the vessel 2 is provided with holes or slots, so that only liquid or concentrated juice issues from the vessel 2, which former may be drawn or let off into measuring vessels 12.
  • a receptacle 13 for water communicates with the apparatus '7 through a pipe 14, provided with a cock or valve, and also connects through a pipe with pump 15 and overflow-pipe 15 whose open end leads or extends into the receptacle 13, the delivery of water for diluting the liquid discharged from the apparatus 7,while the pipe 14 communicates indirectly through a vessel 10 with the outlet-pipe 10
  • the vessel 10, acting as pressure-reservoir and hav ing a fioat 10 is preferably inserted between the pipes 10 and 10", such float eifecting the automatic control of a valve 15 in the pipe 15 through the connections 10 10 and the drum-shaft 10.
  • the regulated delivery of the slices after their partial difiusion in the vessel 2 to the disintegrating apparatus 3 is secured by the radial arms 18, Fig. 2, of two driven shafts 16 17, such arms preventing, on
  • the column of the diffusingliquid contained in the vessel or receptacle 2 should preferably have a height or level not less than four meters. This height can, however, be increased, if desired.
  • the quantity of fresh slices collected above the liquid level in the receptacle or vessel 2 which are fed to the diffusing process can extend about one meter above the liquid-level.
  • Figs.3 to 5 show irrespective of constructive details, which can be altered in many ways, a modification of the apparatus in which a series or battery of difiusing receptacles or vessels of which each is fed with slices are combined in the form of a battery.
  • the pipe 23 in this form is like the pipe 23 of Fig. 1, except that it connects with the casing 3 through the pipe 30, which connects with the receptacle 2, instead of through the said receptacle itself.
  • the operating parts of the apparatus identical with this modification of the apparatus are provided with the reference-numerals corresponding to the parts of the construction of the apparatus according to Figs. 1 and 2, so that only the alterations need be more fully described or explained.
  • 3 to 5 consists of six diffusing receptacles or vessels 2.
  • the number of these vessels can of course be varied, if desired.
  • the vessels are combined in the known manner into a diffusing-battery, which is operated in the usual manner.
  • a pump 25 In the pipe 10, which receives the liquid discharged from the separating apparatus 7, is inserted a pump 25, through whose pressurepipe 24 the discharged liquid is again fed into the battery.
  • the prepared or concentrated diffusion juice is fed through the pipe 40 into the known drawing-off apparatuses of the usual difiusing-battery.
  • This apparatus operates as follows: The solid residue passes from the separating apparatus 7 after lixiviation by the water supplied from the receptacle 13 into a vessel with the worm conveyer- 8 in order to be removed in this manner fromin the above-described manner through the pipe 4, pump 5, and pressure-pipe 6 into the separating apparatus 7--for instance, filterpress.
  • the solid residue is separated from the adhering liquid.
  • the latter again passes to the pump 25 through the outlet 9 into the chamber 10 and pipe 10, with which a pipe 15 communicates, the latter also communicating with the water-receptacle 13.
  • the diffusing liquid is fed in the above-described manner through the pipe 24 of the battery.
  • the fresh slices passing into the battery are fed into the first one of the series of the cells 2 of the diffusing-battery in the known manner, whereupon the diffusing liquid is passed through a pipe 36 into the same body or vessel in order to completely fill up same.
  • the pressing forward of the diffusing liquid into the battery is then interrupted and the liquid is fed to the heating-body 21 through the pipe 19 and pump 20 in order to pass therefrom over new slices of a new diffuser 2that is, a diiferent one from that just mentioned above-until these fresh slices are sufiiciently heated, whereupon the circulation caused through the pipe 19 and pump 20 is interrupted and the diffusion process takes its usual course.
  • the modification of the apparatus shown in Fig. 6 represents the construction of the known diffuser in combination with a series or battery of vessels containing diffusing liquid. Also in this case the corresponding parts of the above-described modification of the apparatus are marked by the same reference-numerals.

  • Another vessel 12 is inserted,which is also adapted to be fed with liquid from the pipe 22 through the cock or valve 12 of an outlet of pipe 22.
  • the operation of this modification is as follows:
  • the diffuser 2 is fed by the conveyer 1 or another suitable device with a proper quantity of fresh slices.
  • the heated juice passes out through the pipe 22 in communication with the heating-body.
  • the pipe 22 is provided with closable outlets A B O D E F G H for each vessel I II III to X. Then the valve of the outlet A is open, the heated juice is fed into the vessel I and circulated through the diffuser until the fresh slices of the same have become correspondingly heated.

  • the quantity of juice corresponding to this quantity of diffusionslices is on the outlet A being closed drawn off into the receptacle 12 through the opened outlet 12 of the pipe 22 in order to be removed from the battery.
  • the quantity of liquid contained in the vessels III to IX of the liquid-battery passes successively into the diffuser 2.
  • the filling of the front end of the liquid-battery from the vessel I in the direction toward the vessel IX is likewise effected systematically by the pump 20, so that as soon as the contents of the ninth vessel pass into the diffuser the diffusion of these slices from these vessels is completed.
  • the liquid from the receptacle X now passes in the same manner into the diffuser.
  • the diffuser 2 becomes quite empty and its whole contents pressed by the disintegrating apparatus 3 and pump 5 into the separating apparatus 7.
