Description

}

  Juice extractor with centrifugal force.

  The invention relates to a centrifugal force juice extractor comprising a juice collector and a

  perforated drum disposed in this manifold, which is

  linked to a drive and can be rotated by the drive. A juice extractor of this kind is already known from DE-A-36 39 804. This known juice extractor has a perforated drum having

  slit-shaped filter, which is connected to a shackle

  ment and is rotated at high speed by this

  tratnement. Under the effect of the centrifugal force

  in this action, the product to be extracted contains

  naked in the perforated drum is separated from its juice and the juice flows into a juice collector. To limit to a small value the proportion of solids in the juice, it is necessary, in a perforated drum of this type,

  to give as small a dimension as possible to the

  filter vertices. Only in this way can the cakes be separated from the juice. However, if one wants to obtain an optimal separation between the solids (cakes) and the liquid (the juice) in a very short time, one must not go below a certain width for the openings. The more we extract from

  juice from the cake using this juice extractor

  naked, the more difficult it is to detach

  perforated drum after the end of juice extraction,

  what, under the effect of the centrifugal force, the partcu-

  the solids sink into the filter openings in

slit shape.

  The object of the invention is to provide an extrac-

  centrifugal force of a constitution such that, although an extraction of OotImal juice is preserved, the solid fraction contained in the juice represents a

  negligible proportion and that after the end of the opera-

  extraction of the juice, the meal may be ex-

  perforated drum without trouble and leaving no residue. According to the invention, this problem is solved by

  the fact that another perforated drum can be fitted together

  axially in the perforated drum and can be connected thereto, that the lateral surfaces of the two perforated drums are formed by bar-shaped bars

  disposed at a certain distance from each other, that

  valles between the outer drum bars are larger than the intervals between the drum bars

  interior and that, in the operating state, the bar-

  the inner drum covers the intervals between

  the bars of the outer drum by forming

filter.

  This means that in the state of

  the bar-shaped bars of the drum

  inside overlap the intervals between the bars

  rods of the outer drum, in form of

  mant of the filter slots. The filter slots are con-

  formed in such a way that, during the extraction of the juice, the

  oilcakes are retained and that the fruit is

  fugitives to the optimal degree in an extremely short time.

  After the end of fruit juice extraction, one separates

  drums from each other so that, thanks to the large intervals between the bars of each drum, the cakes can be removed without leaving

  residue and that perforated drums can be

  easily drilled, by simply plunging them into the water

  or rinsing under running water.

  The bars of the perforated drums are

  parallel or radially in relation to the axis of

  the training and the section of the barrels of the drum ex-

  is larger than the section of the barrels of the inner drum while the intervals between the bars of the outer drum are larger than the

  intervals between the bars of the inner drum.

  In an advantageous embodiment, the bars of at least one drum have a triangular section, a surface of each bar looking towards

  the center of the filter drum, and the bars of the drum.

  Inner ball engaging in the intervals between

the bars of the outer drum.

  According to other features of the invention,

  the drive acts on the outer drum and the drum

  Inner throat is driven by the outer drum, through coaching organs. The bars can form themselves the coaching organs. According to another characteristic of the invention, the bars

  drums are inclined in the direction of rotation.

  Thanks to this oblique arrangement of the bars, the tamper

  Inner ball is pressed to the bottom of the outer drum

  under the effect of the centrifugal force of the drum ex-

  that rotates at high speed and, in this way,

  it accompanies the rotational movements of the outer drum.

  without the need for additional trainers

  tional. An exemplary embodiment is shown in the drawings and will be described in more detail below. In the drawings, Figure 1 shows the perforated drum according to the invention; FIG. 2 represents the perforated drum according to

  Figure 1, with the partially perforated inner drum-

  Figure 3 is a section along the line A-A of Figure 1; FIG. 4 represents on an enlarged scale a partial section of the bars in the mounting state of the

  perforated drums according to Figure 3.

  The perforated drum according to the invention for a centrifugal juice extractor is composed of the perforated drum 1, in which a perforated drum 2 is coaxially and removably nested, as this is

  shown in Figure 1. The lateral surfaces of the drums

  scholarships 1 and 2 are formed by bars 3 and 4 in

  me bars that are arranged parallel to the axis

  5, on flanges 6, 7 and 8. The barbs

  4 of drum 2 have a triangular section, the

  9 of the bars looking towards the center of the drum.

  2. The bars 4 are engaged in the intervals between the bars 3 of the drum 1, thus forming filter slots 12. The drive of the extractor

  of juice acts on the drum 1 and the entrainment of the drum.

  bour 2 is provided by the bars 3 and 4.
