Description
BACKGROUND OF THE INVENTION
This invention relates to a novel compression assembly for a soap
plodder. More particularly, this invention provides a novel
compression assembly which replaces the conventional compression
assembly in a soap plodder and produces a higher quality soap more
efficiently.
The plodding of soap is a well known manufacturing process and was
extensively discussed in U.S. Pat. No. 3,584,355 which issued June
15, 1971 to Charles F. Fischer and will be incorporated by
reference. The invention in this patent provided a compression
assembly for use in a soap plodder including rotating means in a
housing for levigating and homogenizing a soap, the rotating means
including a shank having flights and end flight means disposed
thereon. The compression assembly for the soap plodder in U.S. Pat.
No. 3,584,355 comprised a first compression plate means having a
plurality of bores extending therethrough for partially
plasticizing the soap, perforate means located adjacent the first
compression plate means and closely spaced thereto for forcing the
partially plasticized soap therethrough, and second compression
plate means having elongated slots therein and located adjacent and
closely spaced to the perforate means for preventing blockage of
the perforate means by accumulated soap during processing of the
soap under pressure. This compression assembly provided for the
prevention of the blockage of the perforate means by the mass of
soap processed therein, and substantially increased the speed at
which the soap could be processed over that which was previously
attainable. However, since the issuance of U.S. Pat. No. 3,584,355,
it has been found that by switching the compression plate means
having a plurality of bores extending therethrough with the
compression plate means having elongated slots therein, and adding
another perforate means, preferably a 10 or 18 mesh screen,
adjacent the end flight means disposed on the end of a shank which
levigates and homogenizes a mass of soap, in all cases has
contributed to a higher quality of soap with enhanced appearance
for aesthetic purposes, with improved hardness, toughness and
minimal cracking properties; and can be mechanical refined even
more efficiently than with the compression assembly disclosed in
U.S. Pat. No. 3,584,355.
SUMMARY OF THE INVENTION
It is therefore, the primary object of this invention to provide a
compression assembly for use in soap plodders which substantially
increases the speed at which the soap can be processed thereby over
that which was previously attainable.
It is another object of this invention to provide a compression
assembly for use in soap plodders, which not only will prevent
blockage of the screen by the mass of soap being processed therein,
but will additionally provide for the production of a soap with
enhanced appearance possessing minimal cracking properties.
Broadly, this invention accomplishes all of the foregoing objects
by providing a compression assembly for a housing, and rotating
means in the housing for levigating and homogenizing a mass of
soap. The rotating means include a shank having flights and end
flight means disposed thereon. The compression assembly is located
adjacent the end flight means for permitting uniform plasticizing
of the soap and comprises a first perforate means (preferably a 10
or 18 mesh heavy duty screen) for having the soap forced
therethrough, a first compression plate having a plurality of slots
therein for partially plasticizing the soap and situated adjacent
the first perforate means and closely spaced thereto for preventing
blockage of the first perforate means by accumulated soap during
processing of the soap under pressure from the rotating means. A
second compression plate having a structure defining a plurality of
apertures is also provided adjacent the second perforate means and
closely spaced thereto for further plasticizing said soap and for
preventing blockage of the second perforate means by accumulated
soap during processing of the soap under pressure from the rotating
means.
Still further objects and features of the invention reside in the
provision of a compression assembly for use in a soap plodding
apparatus, which assembly may economically be installed and
plasticizes a soap product having uniform particle distribution and
possessing a higher quality over that which was previously
attained.
These, together with the various ancillary objects and features of
this invention, which will become apparent as the following
description proceeds, are attained by this compression assembly, a
preferred embodiment of which has been illustrated in the
accompanying drawing, by way of example only, wherein:

DETAILED DESCRIPTION OF THE INVENTION
With continuing reference to the accompanying drawings,
particularly with reference to the embodiment shown in FIGS. 1 and
2, wherein like reference numerals designate similar parts
throughout the various views, reference numeral 10 is used to
generally designate a compression assembly for use in a soap
plodder including assembly housing 54 connected to plodder housing
52 by nut and bolt 56. An eccentric shank 58 having worm flights
thereon is rotatably mounted in housing 52. The worm flights have a
graduated flight pitch, and the end flight 60 in abutting and
wiping contact with the entire surface of a perforate plate 12 of
the compression assembly 10. Compression assembly 10 additionally
includes a compression plate 14, a perforate plate 16, and a heavy
duty compression plate 18. The perforate plate 12 includes a heavy
duty mesh screen 26 of 0.03 inch, wire having a plurality of
rectangular plate lugs 20 attached thereto, and rim 24 having a
large central bore 22.
Compression plate 14 is provided with parallel elongated and
substantially rectangular shaped slots 28 extending between its
front face 30 and the rear a face spaced about a large central bore
32. Compression plate 14 additionally includes a plurality of
substantially U-shaped channeled grooves 34 wherein lugs 20
lodge.
The perforate plate 16 includes a thick metal rim 36, a heavy duty
mesh screen 38 of 0.03 inch wire rigidly mounted therein and a rim
40 having a large central bore 42. Compression plate 18 has a
plurality of radially spaced tubular apertures or tapered bores 44
extending therethrough with a large central bore 46. Perforate
plate 12 and compression plate 14 generally include a diametrical
measurement approximately the same, and the perforate plate 16 and
compression plate 18 also generally include a diametric measurement
approximately the same but less than perforate plate 12 and
compression plate 14. When perforate plate 12, compression plate
14, perforate plate 16, and compression plate 18 are assembled for
use, the compression assembly 10 is mounted in the plodder by being
rotatably mounted over the shaft end 48 within plodder housing 52.
The worm 58 carries soap forward introduced therein from a hopper
(not shown) and subjects it to levigation and homogenization. The
soap is forced first through perforate means 12, subsequently
through compression plate 14 which partially plasticizes the soap
and prevents blockage of perforate plate 12, perforate plate 16,
and through compression plate 18 which further plasticizes the soap
and prevents blockage of perforate plate 16 by accumulated soap
during processing of the soap under pressure. Behind compression
plate 16 is a cutting means in the form of a knife 50, preferably a
cut-off knife which rotates with shaft 48 integrally bounded to
shanks 58 and shears soap passing through compression plate 18, or
the like.
FIG. 3 discloses another embodiment of the invention additionally
including between compression plate 14 and perforate plate 16,
perforate plate 62 having heavy duty mesh screen 64 for having
partially plasticized soap forced therethrough, and compression
plate 66 including a plurality of elongated slots 68 for further
partially plasticizing soap. Perforate plate 62 and compression
plate 66 are approximately the same diameter as compression plate
14.
FIG. 4 shows yet another embodiment of the invention additionally
including between compression plate 66 and perforate plate 16,
perforate plate 70 having a heavy duty screen 72 for having
partially plasticized soap forced therethrough, and compression
plate 74 including a plurality of elongated slots 76 for further
plasticizing the soap. Perforate means 70 and compression plate 74
have approximately the same diameter as compression plate 66. In
this embodiment of the invention compression plate 18 is replaced
by the slotted plate 78 as shown in FIG. 5 and has structure
including a plurality of substantially rectangular shaped openings
80 parallel to each other and defining a plurality of parallel
spaced ribs 86 secured to a periphery 88 and recessed as at 82
therein. Large central bore 84 is also defined by slotted plate 78.
It is particularly desirable to utilize this embodiment of the
invention when soap back-up pressure is to be reduced. Slotted
plate 78 may also replace either compression plate 14, 66 or 74
having its recessed portion 82 on the downstream side with respect
to soap movement for increasing colloidal and shearing action on
the downstream side depending on the amount of compression employed
against compression assembly 10.
While the present invention has been described in reference to the
drawings, it will be apparent that permissible modifications,
latitude, and variations can be employed without departing from the
spirit of the invention as defined by the scope of the appended
claims.
