Definitions
- the present invention relates to cellulosic casings that have several layers, reinforced and not reinforced by an inner sheet of paper, as well as to the method of manufacturing it and to the row, also called filiera or head, of extrusion for obtaining said multilayer cellulose gut.
- Cellulosic casings are tubes of different diameters used in the production of sausages.
- the casings that are made from cellulose and that do not contain the fibrous reinforcement referred to can be of small caliber, covering their diameters up to approximately 38 caliber, and large caliber cellulosic, which covers diameters above above This is a division that is recognized in colloquial language in the sector, although it is not an exact division. Even the meaning of each caliber is different, in the case that the same gut has two different calipers depending on whether it is the European caliber or the North American caliber.
- the basic objective of the small-sized cellulose gut is to serve as a temporary container for the meat emulsion that is embedded in it to form the sausage. They are used in "frankfurt" type sausages,
- the gut is removed from the sausage by the manufacturer of the same before its packaging and exposure to the public for sale, but there are markets in which the gut accompanies the product until its sale to the consumer, being the one who withdraws it from the sausage immediately before its consumption.
- the present invention relates essentially to non-reinforced cellulose casings, whether small or large caliber, although it is also applicable to cellulose casings reinforced with a fibrous sheet.
- Said regeneration bath is composed of a solution of sulfuric acid and some salts such as sodium sulfate.
- the gut then passes through different baths with different concentrations of the chemicals mentioned to leave the gut a sufficient residence time that allows the cellulose regeneration reaction.
- the cube produced by regeneration is washed with hot water to remove impurities that may not be left in the regeneration process.
- the gut is plasticized, with glycine being the most common plasticizer in the artificial gut industry. It is then dried, for example, by inflation by pressurized air while the gut is subjected to the action of hot air from outside.
- the gut After drying the gut is humidified in order to make the gut reach the final stage of smooth gut with a constant degree of humidity.
- This smooth casing is generally not usable by the stuffer, especially the smaller sizes and must be normally prepared for use.
- This preparation phase or “convertmg” consists of the puckering or pleating of the gut to form hollow, self-sustaining sticks in which the length of the gut is reduced 100 times or more in length, so that it unites these sticks with 25 cm in length can contain 25 meters or more of gut.
- the guts are humidified to the desired level of hu m age, so that the gut can be pleated without breaking but without exceeding the limit from which the gut would cling to the pleated mandrel. so that it made the pleating operation movable.
- lubricants are added to the gut that reduce friction between the gut and the handle, or between the gut and the pleated wheels. These luo ⁇ cantes will also serve to reduce friction with the drawing elements of the sausage at the time of using the gut.
- the gut in addition, is printed previously to its pleated, with brands, logos or advertising motifs that identify the sausage in it or the manufacturer thereof.
- sausage makers ask gut suppliers that they have a part, or all, of the gut of a color that is clearly striking and different from that of the sausage.
- the objective of this chromatic differentiation is that the operator in the peeling or peeling control operation easily detects the existence of unpeeled pieces of gut in the sausage.
- casings have been made with stripes of different colors and different widths, such as those described in US Patent 3,334,168, of Majewski.
- the presence of these stripes pursued a double objective, on the one hand the identification of the correct sausage peeling as indicated above.
- the existence of stripes allows the identification of the type of sausage embedded in each casing in question. This factoi can have its importance in the internal manufacturing of the product by the manufacturer and can also be a factor of identification by the consumer in cases where the sausage is sold with the unpeeled gut, at the same time it serves warning that the striped sausage is unpeeled.
- a second system to detect the gut that it remained still attached to the surface of the sausage has been e_ colorize the gut in its entirety with a striking color and differentiated from that of the sausage embedded in it. Colors such as blue, red or orange were used to detect the presence of unpeeled gut remains on the surface of the sausage embedded in it.
- the presence of dye in the gut used to color the stripes or to color all or much of the gut itself, has sometimes caused the detachment of colored particles that, despite having a small size in relation to the size of the sausage, cause the rejection by the consumer, with the consequent cost and loss for the manufacturer.
- the colored gut particles can be released in the different phases of the manufacturing process and use thereof.
- a third problem that occurs in the color of the gut is the tendency to slip at the time of winding.
- the presence of the pigment in the gut reduces the adhesion between the gut by making the surface of the gut very plastic. This plasticity also affects in the pleated for ⁇ which makes it more complicated.
- the colored gut occasionally presents printing problems.
- the presence of the pigment reduces, depending on the pigment in question, the adhesion of the printing inks, causing difficulties in it.
- FIG. 4 A section of the gut according to the invention is shown in Figure 4.
- the 15 and 16 layers are designated as outer layers, while the inner layer is the one designated in the drawing as
- the object of the present invention is a cellulose casing for sausages composed of at least three concentric layers of regenerated cellulose, of which the two layers in contact with the outside, that is, those of greater and lesser diameter, respectively, are made of colorless and transparent regenerated cellulose and the interior or interior are made of regenerated cellulose to which other substances have been added, such as pigments, fumes, extracts of flavors, spices or plastic materials that give different performance to the gut than it would have if all of it were made of regenerated cellulose.
- Another object of the present invention is a cellulosic gut in which the extrusion of the regenerated cellulose colored from the inner layer (or interiors where appropriate) is discontinuous so that not all the gut is colored but that colored longitudinal portions are appreciated and colorless, the colored portions being one or more colors.
- Another object of the present invention is a cellulosic casing in which the extrusion of the colored regenerated cellulose from the inner layer (or interiors where appropriate) is discontinuous so that colored and colorless longitudinal portions are appreciated and the colored and longitudinal portions have a zigzagging figure.
- Another object of the present invention is a cellulosic casing in which the extrusion of the colored regenerated cellulose from the inner layer (or interiors where appropriate) is discontinuous, so that colored and colorless longitudinal portions and the colored and longitudinal portions are appreciated they are discontinuous in the longitudinal direction so that a colorless gut portion is followed by a colorless portion and vice versa.
- the object of the present invention is a method of manufacturing a cellulosic casing for sausages obtained by extrusion of at least three layers concentric regenerated cellulose, of which the two layers in contact with the outside, that is, those of greater and lesser diameter, respectively are made of colorless and transparent viscose and the interior (or interiors, if any) is made of viscose colored although the extrusion thereof is discontinuous, so that not all the gut is colored but that colored and colorless longitudinal portions are appreciated, the portions being colored, colored with one or more colors.
- the object of the present invention is a row or filtrate of circular viscose extrusion for the production of cellulose gut for sausages capable of allowing the simultaneous and concentric passage of at least one viscose layer to which some other substance has been added. , continuous or discontinuous, so that it is embedded in the center of the gut and is covered inwards and outwards by transparent regenerated cellulose.
- FIG. 1 shows a conventional row, filtrate or extrusion head as described in Majewski Patent 3,334,168.
- FIG. 2 shows a row, edge or extrusion head capable of preparing a casing according to the invention.
- FIG. 3 shows a second variant of a row, filiera or extrusion cinnamon capable of preparing a tupa according to the invention.
- FIG. 4 shows a section of the acid gut with the present invention.
- FIG. 5 shows an enlarged and sectional representation of the casing manufactured according to the invention.
- FIG. 6 shows the flow scheme A shows the viscose flows of the filtrate or extrusion head of Figure 2.
- Figure 7 shows the flow scheme B shows the viscose flows of the filtrate or extrusion head of Figure 3.
- Figure 1 shows a conventional row, filtrate or extrusion head, as for example, can be described in US Pat. No. 3,334,168 to Majewski, used for the manufacture of regenerated cellulose casings, by which the viscose is extruded through of an annular row inside a coagulating and regenerating bath to produce a tube of regenerated cellulose. Then, the tube produced by regeneration, is washed, plasticized, for example, with glycerma and dried, for example, by inflation under air pressure. After drying, the gut is rolled, obtaining coils of several thousand meters of what is called in the "smooth gut" sector.
- FIGs 2 and 3 show two different embodiments of an extrusion head with which the cellulosic casings object of the invention are obtained.
- the extrusion head (1) is observed, which is immersed inside the coagulant and regenerating bath (2). From the annular hole of this head (4) comes the regenerated viscose in the form of a tube (3).
- Figure 3 shows an alternative embodiment, in which the extrusion head (5) provides in a reduced space the strangulation of the viscose flows (6, 7 and 8).
- the separation of viscous is given by the feeding of different viscous by different conduits (9, 10 and 11).
- the different types of viscose follow the path indicated by the arrows, as indicated in the flow chart B, until they reach the extrusion mouth where the viscose that regenerates (3) comes into contact with the coagulating and regenerating bath.
- Figure 4 shows a section of the casing (3) in which both the outer layers (15) and (16) are observed, as well as the inner one (17) to which additional substances have been added, thereby forming a multilayer and tubular cellulose gut.
- Figure 5 shows a representation of a gut section in which the three manufactured layers are shown. It shows that the interior (17) is embedded in the interior of the two layers e> te ⁇ nas (15) and (16). This figure corresponds both longitudinally and transversely ⁇ na section gut ob ⁇ etc of the invention.
- viscous flows are introduced through an extrusion head such as that described.
- the viscose used for the formation of the inner layer which is not in contact with the outside, has been colored by mixing pigment ⁇ viscose by conventional means.
- the blue pigment of generic name Pigment Blue 15: 3 has been used whose chemical compound is Cu-phthalocyanma (beta) and which is manufactured by the CIBA firm with the brand "Blue 4GNP” ® .
- Said extruded viscose is regenerated in an acid bath, washed, plasticized and dried using, in any case, the conventional methods already described in the literature manufacturing cellulose casing for sausages.
- Both products are wound in a conventional winding machine.
- the gut made according to the state of the art caused that, after about 700-800 meters of winding, the glove began to have a certain bluish color that intensified as the glove kept in contact with the gut .
- the gut made in accordance with the present invention kept the glove white, with color unchanged during the entire time of the test, and even for a longer period, until it exceeded 1,000 rolled meters, in which it was stopped carrying carry out the experience in view of the difference in the result.
- Said extruded viscose is regenerated in an acid bath, washed, plasticized and dried using, in any case, the conventional methods already described in the manufacturing literature of cellulosic casing for sausages.
- the modification is carried out in the equipment and in the flows used in the manufacture of the casing according to the invention so that guts are made in which the colorless and inner outer layers have different thicknesses.
- Example 1 The test indicated in Example 1 was performed by applying the glove in a length of 700-
- External layer Z (No. 15 in figure 4) was defined as the one that will be in contact with the pleating wheels and External layer Y (No. 16 in figure 4) the one that will be in contact with the sausage at the time of drawing. The following results were observed
- the thickness of the outer layers Y and Z ( Figure 4, numbers 16 and 15) can be up to 1 mir, although the guts whose outer layers Y and Z are not less than 3 microns thick are preferred. in order to avoid the risk of the formation of aggregates of pigments that may occur and that it has been observed that they may have that thickness and, in this case, may lead to their contact with the outside.
- the colorless gut was rolled properly presenting the coils with an aspect of stability, consistency and good winding that made them perfectly manageable, their compaction was adequate.
- the gut colored in its entire mass by the traditional method defined as a pattern in example 2, with an absorbance of 0.23 to 637 nm, showed lateral sliding in the coils, with a badly wound.
- the coils had no consistency and their compaction was not adequate. It was necessary to increase the tension to 1.6 kilopondios (15.68 newtons) to obtain well-wound coils with compaction adequate. These coils wound with this higher tension can generate problems throughout the storage period.
- Example 2 was wound with a pressure of 0.9 kilopondios (8.82 Newtons) in an appropriate manner, presenting the Dobmas with an aspect of stability, consistency and good winding that made them perfectly manageable, their compaction was adequate, as was the from the colorless gut.
