Definitions

  • ABSTRACT A juice extractor comprising a motor driven screen
  • the invention relates to a juice extractor with automatic pulp discharge in which a motor driven screen basket is rotated about a vertical axis and is provided above the surface of its bottom with a grating disc which rotates with the screen basket and against which the material to be extracted is pressed.
  • the material to be extracted is introduced into the upper end of the screen basket by a filler tube which extends almost downwardly to the bottom of the screen basket so that the material after being disintegrated by the grating disc is thrown by centrifugal forces against the inner surface of the screen basket.
  • the juice penetrates the wall of the screen basket, while the pulpis conducted to an outlet above the upper edge of the screen basket.
  • This outlet comprises a discharge spout projecting from the cover of the housing of the juice extractor.
  • the juice extractors nowadays developed have the advantage that they operate continuously, so that one is not required to interrupt the operation of the juice extractor for the purpose of removing the juiced pulp which has been deposited on the inner surface of the screen basket.
  • the object of the invention is a juice extractor with automatic pulp discharge which does not possess the just mentioned disadvantages.
  • the juice extractor of the invention extracts juice from any type of material without any difficulties and without any danger that the pulp will clog the screen basket.
  • the juice extractor of the present invention employs a simple conventional insensitive electric motor having a speed of, for instance, 3000 revolutions per minute.
  • the juice extractor of the invention employs a pulp stripping device provided with vertically spaced and oppositely inclined stripper segments which can be brough in and out of engagement with the inner surface of the screen basket, whereby each segment displaces a ring of pulp on the inner surface of the screen basket upwardly into the operating range of the next higher segment until the uppermost stripper segment discharges the pulp over the edge of the screen basket.
  • the pulp is not discharged by centrifugal force from the screen basket but is actively engaged by stripper segments and is moved step-by-step towards the upper edge of the screen basket and finally over the edge of the same so that it is not necessary to employ an electric motor having a very high speed. In fact, the conveyance of the pulp is practically independent of the speed of the motor.
  • the pulp stripping device is provided with two groups of stripper segments which alternately may be brought into engagement with the inner surface of the screen basket and may, of course, also be removed therefrom.
  • the invention is also distinguished by a plug which is insertable and removable from the filler tube of the juice extractor.
  • This plug may be arranged and constructed to operate an adjusting device for the pulp stripping device.
  • the drawing illustrates by way of example a particular embodiment of the juice extractor.
  • FIG. 1 illustrates a perspective view of the juice extractor with parts cut away so as to have a view of the interior mechanism.
  • FIG. 2 is a vertical sectional view of a screen basket and also shows in an elevation view the pulp stripping device therein.
  • FIG. 3 is a top elevation view of FIG. 2.
  • FIG. 4 is a vertical sectional view corresponding to FIG. 2, except that the pulp stripping device is illustrated in another position.
  • FIG. 5 is a top elevation view of FIG. 4.
  • FIG. 6 is a sectional view which illustrates the mounting of the screen basket on the upper end of the motor shaft; and the FIGS. 7, 8, 9 and 10 show each a different position of the means for adjusting the pulp stripper device.
  • the juice extractor of the invention is provided with a housing 1 in the lower portion of which is arranged an electric motor 2 with a vertical armature shaft 3.
  • the upper end of the armature shaft 3 has attached thereto a screen basket 4 and a grating disc 5.
  • FIG. 6 illustrates clearly that the bottom wall 6 of the screen basket 4 has placed on top of it the grating disc 5 and both the bottom wall 6 and the disc 5 are clamped by a cap nut 8 against a collar 7 on the shaft 3, whereby the cap nut 8 engages'a thread 9 on the uppermost end of shaft 3.
  • the central holes 10 and 11 of the bottom wall 6 of the screen basket 4 and of the grating disc 5 and also the corresponding cross section of the shaft on which they are attached are noncircular in order to avoid an undesired rotary movement of the basket 4 and of the grating disc 5 relative to the shaft 3.
  • the housing 1 has at its upper end a circular cover 12 with a downwardly extending flange edge 13.
  • the cover 12 is provided with an eccentric filler tube 14 for the introduction of the material to be extracted.
  • the filler tube 14 is provided with a larger portion 14a which extends into the interior of the basket 4. In fact, the lowermost end of the portion 14a terminates a short distance above the grating disc 5, while the smaller portion 14b of the filler tube 14 projects upwardly from the cover 12.
  • a plug 15 may be inserted into the tiller tube 14 and removed therefrom, and the upper end of the plug 15 is provided with a bandle 16.
  • the plug 15 is provided with a longitudinal groove 17 in which a swivel member 18 is rotatably supported about a horizontal axis between its ends in such a manner to form an acute angle with the longitudinal axis of the plug 15.
  • This swivel member 18 is used for adjusting a pulp stripper 19.
  • the pulp stripper 19 has a tubular hub 20 which is secured to the center portion of a vertical shaft, both ends of which are rotatably supported in two vertically spaced bearings 21 and 22 on the outside of the lower portion 14a of the tiller tube 14.
  • the particular construction of the bearings 21, 22 which form a hinge is not of particular importance.
  • the stripper 19 is provided with five arms 20 which are attached to the hub 20 and carry each a stripper segment 23,, 23 23 23, and 23 in such a manner that the stripper segments are spaced in vertical direction and are also offset with respect to each other. Three of these segments are arranged on one side and the other are arranged on the other side of the hub 20.
  • the stripper 19 may be pivotally adjusted to two positions of which one is illustrated in the FIGS. 2 and 3 in which the stripper segments 23,, 23 and 23 engage the inner surface of a cylindrical portion 24 of the screen basket 4. In the other position illustrated in FIGS. 4 and 5 the stripper segments 23, and 23 engage the cylindrical portion 24 of the screen basket 4.
  • All of these stripper segments 23 to 23 correspond to short sections of helical faces, all having the same inclination, whereby the lower end of the segment 23 is arranged only a short distance above the grating discS, while the lower end of the segment 23, is arranged approximately in the level of the upper end of the segment 23, and the lower end of the segment 23, about in the level of the upper end of the segment 23,, etc.
  • the upper end of the uppermost segment 23, is arranged in the level of the upper end of the basket 4 where an outer flange 25 is provided.
  • the screen basket 4 has between its nonperforated bottom 6 and its cylindrical screen portion 24 a somewhat conical screen portion 26 which gradually merges into the cylindrical screen portion 24.
  • a small downwardly curved portion 27 which merges into the bottom wall 6.
  • the extracted juice leaving the screen basket 4 runs downwardly on the inner surface of the housing 1 into an angular collecting trough 28 provided in the housing and this trough is provided with a discharge spout 29.
  • the hub 20 of the pulp stripper 19 has attached thereto a radial pin 30 which extends through a small horizontal slot 31 in the lower part 14a of the filler pipe and cooperates with the swivel member 18 in a manner as is illustrated in the FIGS. 7-10.
  • the swivel member 18 is rotatably supported in its center by a horizontal pin 32 which is attached in the plug and this pin 32 is surrounded by a diagrammatically indicated torsion spring 33 which has the tendency to rotate the swivel member 18 counterclockwise when viewing the FIGS. 7-10, so that normally the upper end of the swivel member 18 engages a side wall 34 and its lower end engages the other side wall 35 of the groove 17.
  • the juice extractor of the invention operates as follows:
  • the material to be extracted is urged by the plug 15 against the grating disc 5 and is shredded by the latter and then by centrifugal force is thrown onto the conical screen portion 26 whose rise angle a is so selected that the material during'the normal speed of the motor 2, for instance about 2900 revolutions per minute, is moved upwardly on the same and during the transfer to the cylindrical screen portion 24 is deposited thereon in the form of a ring 36.
  • This ring portion is designated with 36,.
  • the stripper segment 23, engages the pulp ring 36 so that the same, in view of the rotation of the screen basket 4, is advancd upwardly a distance equal to one height of a segment and thereby comes into the position 36, according to FIG 2.
  • the segment 23, becomes effective and moves the ring 36 into the position 36, as shown in FIG. 4, This operation is repeated so that next the segment 23, moves the ring 36 into the position 36, and the segment 23, moves the ring 36 into the position 36,.
