Hera division of multicolored detergent strands

Priority: November 5, 1971 »G-roßbri tannien, lir.51 476/71

The -Eiri'indication refers to a procedure and a Device for the continuous production of multicolored detergent strands, in particular "soap strands". Of the For the sake of simplicity, only soap is used in the following, but this term is intended to refer to normal soap based on salts of fatty acids as well as synthetic Cover detergent raw material and ΰ-euiic both.

Multi-colored striped or marbled soap strands are known and their production is naturally more complicated than the manufacture of a single color strand.

Various methods are used or suggested for the production of multicolored soap strands »

The invention relates to an improved Se if ens press and a method of using the improved Soap extruder for the production of multicolored bars of soap, especially striped soap strands. The discovery Also includes striped soap strands, which were colored by the new process.

fed two differently colored G-round soaps produced somewhere, but with the soap strand obtained a striped one is.

A strand of soap with sharp stripes is also made according to of the invention using the improved soap extruder obtained when the paint is injected in a location as far as possible from the outlets the barrel is removed, preferably immediately after the hopper feeding the extruder.

Such an arrangement would naturally be a better one homogeneous distribution of the color within the soap will result, as an arrangement with the color closer to the barrel outlets is injected.

However, the striped appearance of the soap strand can if desired by changing the location of the color injection can be modified along the length of the barrel.

The method and apparatus according to the invention will now be discussed will be further described with reference to the schematic drawings which illustrate:

Prop. 1 shows a longitudinal section through the essential part of soap extruder according to the invention and

Figure 2 is a perspective view of one embodiment of the Apparatus comprising the apertured plates with the tube assembly.

According to FIG. 1. The apertured front plate 4 is located in cone 1 near the outlets of the barrels 3 , the apertured end plate 5 is located further rearward in cone 1. The pipe system 6, which connects a group of openings in both plates, is horizontal and parallel to the cone axis. Soap mass A, conveyed by the press screw 7 and coming from barrel 2, goes through openings 9 (Fig.2) in space 10 and is pressed into ttaum 12 through openings 11 (Vxg, Z).

-A-

Soap mass B (of a different color from A), conveyed by press screw 8 and coming from barrel 3, goes through tubes 6 and is pressed into space 12, where soap mass A meets it. The combined soap mass is extruded through the perforated outlet plate 13 to form a soap strand with a strip- like appearance.

Separate flows of soaps A and B passing through plate 4 are effected by partition 14 »

Pressure regulator 15, located in the cone between the two perforated plates, allows effective control of the pressure in the Cone"

In Fig. 2 is an embodiment of the openings on the end plate 5 shown.

The tubes 6 are preferably located in the longitudinal direction in wesentli Chen around the central axis of the cone to the smallest To give reduction of fit of the extruder. Depending on the fit and size of the extrusion press the number of tubes can vary from about 5 to about 40.

The total area of the tube outlets for soap B with respect to the total area of the openings for soap A on end plate 5 should be set up to adequately cover the soap mass through the two augers to correspond to the pressures exerted.

It was found that a clear width of the tube outlets for soap B from $ 55-60 compared to a clear width of the openings for soap A of 40-45 ^ on the end plate very good processing to soap strands results in a completely satisfactory appearance.

A satisfactory arrangement of openings on the end plate as shown in Fig. 2 may consist of, for example

12 holes of 8 mm diameter) "10 rectangular slots of 9 χ 32 mm)

which arrangement had an area ratio of 5T / ° B to 43 $ A '"

Indeed, this opening arrangement essentially determines the color pattern in the strand and his stripe-like appearance,

Very attractive modifications of the strip-like appearance, which correspond to the various consumer wishes, can also be achieved by simply mounting plates with various openings on the extrusion outlet can be achieved through which the soap mass is extruded.

The J? Ig. 3, 4 and 5 show some cross-sectional views the many variations of color patterns in the soap, which result from an array of holes on the end plate through Use of different outlet perforated plates can be obtained »

Fig. 3 shows a cross section of the soap mass, produced according to the method according to the invention, just before the passage through the die plate at the end of the extruder using an end plate having the above arrangement of Openings.

Figo 4 shows three opening positions of a perforated plate, which different stripe patterns in the finished soap bar generated. D and E can be obtained at the same time by using a perforated plate with two openings,

Fig. 6 shows a plan view from above of the bar of soap punched from this strand,

Fig. 7 shows another striped soap bar punched from a strand which passes through the perforated outlet plate E of Fig. 4 was extruded.

Of course, when the striped soap bar is made by the method of the invention, the two should Different colored clay masses are pressed together by the screw presses in the extruder at roughly the same speed and promoted in order to avoid the cutting of strips, which can cause irregularities in caused the sexton.

In order to achieve a good regularity of the strips, it is also desirable to operate the extruder at a temperature of about 30-55 ° C, preferably in the range of 35-45 °, depending on the amount of fat or the composition of the soap ο too high Temperature during extrusion: would make the soap mass too soft for extrusion _; It is also important that the temperature is kept at a constant level during extrusion, otherwise the strips would become irregular.

It was also found that there was a feed ratio before 25-75% by weight of soap A and 75-25% by weight of soap B in general Provides strands with a satisfactory striped pattern.

Usually the compositions of the Basic soap, which in the inventive device can be processed, not by those used for the production of white or monochrome soap strands be ,, although the improved extruder is preferred for The processing of real soap strands is used, which is sodium soap made from mixtures of coconut oil and tallow fatty acids it is also useful for processing strands made from other synthetic detergent mixtures consist of a consistency comparable to that of real soaps.

309819/03 3 2

Examples of suitable soap compositions are sodium soaps made from mixtures of 30-90 % by weight of tallow fatty acids and 70-10% by weight of nut oil fatty acids, which are greased with, for example, free fatty acids up to 20% by weight of the total composition.

Examples of synthetic detergents which can be processed according to the invention include the alkali salts of higher (C ₁₀ -C ₂₀ ) Fe ^ alcoholsulfur acids, higher (Cjq-Cjq) alkylbenzoisulphonates, the sodium or potassium salts of higher fatty acid monoglyceride sulfuric acids with 14-18 carbon atoms in the Fatty acid group, AHhylenoxydkondensationsprc product · of (C ₈ -G ₁₀ ) alkylphenol or of (C ₁₂ -C ₂₀ ) fatty alcohols and the alkali sulfates of ethoxylated fatty alcohols.

One embodiment of the invention will now be exemplified described.

Piled white soap is poured through a funnel into the screws of a modified double twin vacuum extruder fed in. Thanks to the partition between the augers, two streams of soap go separately through the barrels in a parallel direction. Paint is injected into a barrel at a point about halfway past the first set of twin barrels. Soap A and B happen again separate a vacuum chamber and continue through the second series of twin runs as shown in FIG.

The method according to the invention not only produces punched Soap bars of striped appearance, but can also can be used to create pieces which have a stripe pattern radiating from their center when the cut ones leaving the extrusion equipment Strands are punched in the axial direction, the term axis being the axis of symmetry of the extrusion apparatus leaving strand means.
