Description

Process and device for the production of a plastic product, z. B. a confectionery product such as ice cream. The present invention relates to plastic products, z. B. confectionery products, and relates to a method and a device BH Manufacturing. In particular, the invention relates to frozen confectionery products, such as ice cream.

Colorful or multi-flavored ice confectionery products, i.e. ice cream, water ice, Sorbets etc. have so far been made by simultaneously extruding the types of ice cream different tastes or different other properties by one or multiple nozzles are created in a mold or container, the different flavors can thus be stored in separate layers or by suitable control of the dispensing device be mixed. For "popsicle" type confectionery products, the strips or cores of ice cream generally lengthways across the product and thus produce the same appearance, with the exception of the color, as that of the multi-storey confectionery products the The present invention relates to a method and apparatus for manufacturing a new product made from biscuit or similar materials that deals with the previously known methods or devices can not be produced. The new Product consists of two different materials, which spiral around each other are sinuous, and are made by being formed in a special way A strand of Liskrem or similar material is extruded into a container Novel product can be made according to the method according to the invention by the special Type of simultaneous extrusion of at least two different types of a plastic material can be formed by a nozzle, and the method is characterized in that the different types of plastic material are wrapped around each other in the nozzle while never being separated from each other, so that # they look like a strand of spirally intertwined ribbons exit the nozzle, the nozzle spiraling with each other during extrusion intertwined ribbons turned in the opposite direction to the spiral thread of the exiting ribbons so that the strand emerges without rotation, and then the strand into a container is inserted.

The device used to carry out the method according to the invention consists of at least two separate Wu guides for different plastic Materials and at least one nozzle connected to it with an elongated Passage through which the materials can be extruded and the device is characterized in that the nozzle has at least one winding division in the passage dividing the passage into two separate channels, the different plastic materials being separated from one another by theirs Feeds are fed into the separate channels, and the # means for rotation the DUse and the sinuous subdivision are provided o At this It should be emphasized that the rotation of the nozzle itself has nothing to do with the formation of the spiral ribbons, but only serves to prevent the rotation of the strand, which would otherwise inevitably occur.

Such rotation must be prevented because the strand is subsequently is placed in a container and rotation is the spiral shape of the end product would destroy.

U.S. Patent 2,779,970 discloses an extrusion die, in which a spiral-shaped swirl is generated by rotating the nozzle. This patent specification describes a completely different way of working, because this is where the nozzle is used for generation of the twist, while in the present invention the spiral-shaped looping generated within the nozzle by a given subdivision and then the nozzle is only rotated for the reason to cancel the turning effect again; the The nozzle is rotated here for a different purpose. By the way, the in the said US patent disclosed nozzle of a completely different task, namely the manufacture of electrical wires, cables and the like and could not dasu used at a conference; tproduct, e.g. D. Ice cream, a spiral wound Configuration to be given as the confectionery product occurs with this known nozzle Torsional forces would not stand.

German Patent 939 853 discloses a molding machine for Extruding candy sticks, the material being twisted by a spiral Pipe guide is extruded.

Here, however, the emerging material rotates and it is found no disclosure in this patent in the sense that this rotation of the material strand is to be canceled by turning the nozzle in the opposite direction; when inserting the material strand in a container, e.g. B. a freezer form, the swirl effect would be lost again and the molding machine disclosed in this patent is therefore for the formation of the In addition, the German patent is concerned only with candy sticks, a material that is completely different from an ice cream product is, and certainly does not concern the formation of products from different ones Kinds of plastic material, e.g. B. ice cream, as according to the present invention.

An embodiment of the invention will now be made with reference to the accompanying drawings Drawings explained. In the drawings, Fig. 1 is a plan view of a Arrangement of the nozzles according to the invention with partially broken parts; Fig. 2 shows a sectional view along the line 2-2 of FIG. G.1 in the direction of the arrows ; 3 is a view in vertical section, on an enlarged scale and with broken away Share a nozzle that turns a frozen confectionery product into a conventional freezer mold extruded; fig. 4 is a sectional view taken along line 4-4 of FIG. 3 in FIG Direction of arrows; FIG. 5 is a sectional view taken along line 5-5 of FIG. 3 and FIG. 6 a perspective view of a frozen confectionery product according to FIG the invention,.

A nozzle 10 according to the invention can be part of an arrangement 11 Similar nozzles 12 and 13 (Fig. 2) illustrate the needs of mass production to meet.

Each nozzle 10 (FIG. 3) has a nozzle part 14 which is tubular May have shape and an elongated passage 15 has. A sinuous subdivision 16 with e.g.

2 1/2 full turns of a spiral is e.g. by soldering inside attached to the tubular surface of the DUsteil 14 and divides the elongated Passage 15 into two separate, elongated channels 17 and 18.

A vertical duct 19 and an adjoining room 20, both above of the nozzle part! 4 arranged are in vertical connection with the channel 17. A thin 9 semicircular plug 21 (Fig. 4), which is placed between the inner wall of the aise, which formed the elongate passage 15 and which the winding partition 16 which the upper end of the channel 18 forms, is inserted and provides a barrier which A vertical conduit 22 separated the channel 18 from the space 20 and the conduit 19 and a connected, annular space 23 (Fig. 5) which the nozzle part 14 in the Near the upper end of the elongate passage 15 transversely surrounds are located in free cross-communication with the channel 18 through a slot 24 which is in the Nozzle part 14 is formed.

Suitable means, such as Bö a gear 25 (Fig. 2), which at the outer surface of the nozzle part 14 is attached, are on the transversal len central surface of the nozzle part 14 provided9 around the DUsteil-14 during the extrusion of the frozen confectionery material to rotate so that in cooperation with the twisted Subdivision 16 a strand 26 of a spirally striped, extruded, frozen Confectionery product is produced, as shown in FIG. Similarly arranged gears 27 and 28 (Fig. 2) drive nozzles 12 and 13, respectively. Idler gears 29 and 30 match the gears 27 and 28 to the gears 27 and 28 with the same Speed and in the same direction of rotation as gear 25 o The Driving force to rotate the nozzle assembly 11 can be generated in any way be e.g. B. by a pneumatic Cylinders with a rack and pinion gear or, such as B. shown in Figs. 1 and 2, by a gear motor 32 with a driven gear 32a. The driven gear 32a matches the gear 31, which cooperates with a driven gear 33, which the power from the motor 32 transfers to a conventional gear train 34, 35, 36 and 37. The nozzles 10, 12 and 13 are therefore moving at the same speed and in the same direction by the motor 32, the driven gear 32a, the gear 31 and the gears 25, 27, 28, 29 and 30 driven in the manner described above The lines 19 and 22, the space 20 and the annular space 23 are all vertical in one set aligned plates 38 arranged by depressed tenons or derglo (Figs. 2 and 3) are kept aligned, allowing the stacked panels 38 it, the nozzles completely apart for thorough cleaning without difficulty gain weight. The gear 31, the gear motor 32, the DUsenteile 109 12 and 13 and the intermediate gears 29 and 30 are also within the vertically oriented, stacked plates 38 mounted and rotatably supported So is a distributor plate 39 (Fig. 1) on top of the vertical stack of plates 38 with a set of holes 40 and 41 which form the lines 19 and 22 in part. Immediately below the divider plate 39 is an upper flow plate 42 (Figs. 2 and 3), the is provided with a pair of recesses 43 and holes 44 which are in alignment with the holes 40 and 41 in the distributor plate 39 also the lines 19 and 22 in part, while the recesses 43 also form the space 20 for the vertical Form a connection between the channel 17 and the line 19.

The lower flow plate 45 immediately below and aligned with the upper flow plate 42 has a recess 46, which the annular space 23 forms, and part of the connected conduit 22 for transversal Connection to the channel 18 through the slot 24f in the nozzle part 14 straight below the semicircular plug 21, which separates the channel 18 from the space PO, is formed.

The drainage plate 47 (Fig. 2) is directly below the lower flow plate 45 arranged and aligned with ilir.

The gear 31, the intermediate gears 29 and 30 and the gears 25, 27 and 28, which go to the DUcen. 10, 12, and 13 are all for rotation purposes carried by the gear plate 47 in the manner described.

Bin n striped frozen confectionery 48 (Figs. 3 and (i) through Extrusion of two different types of frozen confectionery in plaatischem State generated by the nozzle 10, while the DUsteil 14 about its longitudinal axis is rotated. The two types of confection form a spiral when they come out of the nozzle come out, owing to the effect of the twisted subdivision on the exiting Material.

When extruding frozen confectionery, the Alse 10 in the mold can be inserted so that # the open end of the nozzle is adjacent to the ground of the mold and then pulled out in some convenient way while the ice cream is extruded through the nozzle, or wi. e shown in Fi @ 3, the Both streams of biscuit exiting nozzle 10 can be directly in the mold 49 are deposited in generally helical layers. The ones so discarded Layers of ice cream in shape 49 extend across the bar in general alternating bands 51 and 52 and give the confectionery product a striped appearance As shown in FIG. 6, a typical frozen confectionery product has 48 a stick 50 that goes into the confectionery 48 after the mold has been filled, but before the ice cream is fully cured, is used. The strips 51 and 52 of the different Bies or the like create an unusual appearance, which has so far been found in other, known frozen confectionery products has not yet been achieved. It should be noted, however, that the strips 51 and 52, di <sin, Fig. 6 are shown, idealized to a certain extent are drawn and muges do not appear so regularly in practice, but stout this generally does not make the product attractive in appearance.

In operation (Fig. 3) a frozen confectionery product 52, such as zo B. conventional ice cream or sorbet or a semi-frozen water ice by the Line 19 and space 20 in channel 17, that of the twisted subdivision 16 and the elongated passage 15 is formed in the nozzle part 14, extruded. Another type of frozen confection 51, the ordinary ice cream or sorbet can and differ from the frozen confectionery 52 in taste, type, structure and / or parbe differs, is through the line 32 and the annular space 23 in the slot 24, which is in communication with the fanal 18 in the nozzle part 14, is extruded.

The gear 31 and the gear motor 32, which the gear 25 in the above described drive rotates the nozzle part 14 and the winding Subdivision 16 therein, while the frozen confections 51 and 52 along the inclined sides of the partition 16 in the nozzle 10 are extruded into the mold 49 The direction of rotation of the nozzle i opposite to the direction of rotation in which the product comes out of the nozzle. This will remove any inclination of the exiting Product to rotate during extrusion is reduced to a minimum and the creation of a stiff, striped product is thus supported.

The frozen @onfektsorten 51 and 52, which are placed in the mold 49 are going from the plastic state to the frozen Suètand cooled by any suitable method, such as e.g. B. by dipping the form 49 in a cold bath. The stick 50 or other means of handling the frozen Confectionery 48 is inserted into the bottom of the striped and frozen confectionery 48, before the confectionery 48 hardens and is in the partially exposed position frozen perpendicular to the bottom of the confectionery 4B as shown in FIG. the Form 49 and the confectionery frozen in it are removed from the freezer after solidification removed and warmed, e.g. B. thereby that the outer shell of the form 49 with a warm water bath is brought into contact with the frozen confectionery 48 on the Surface to melt slightly and thus its removal from the mold 49 for the purpose Enable packaging, shipping, sale and consumption.
