Description

[0001] The invention relates to an attachment for making spaghetti ice cream for an ice cream machine. State of the art

[0002] DE 38 25 855 A1 discloses a machine for producing so-called spaghetti ice cream, which includes a machine housing and in which a motor-driven piston press presses an ice cream mass to be filled through a perforated matrix in order to extrude the ice cream in the shape of spaghetti.

[0003] With this special type of ice cream production machine, which is usually used in the commercial sector, for example in iced coffee shops, the ice cream mixture to be processed must be produced separately.

[0004] Ice cream maker machines for home use have been available for some time. For example, reference is made to DE 20 2023 103 339 U1. This patent discloses a machine for making ice cream, gelato, frozen yogurt, sorbet, and similar products. With such machines, the user places a number of unfrozen ingredients into a container. The ingredients are then stirred by a mixing mechanism, while a cooling mechanism simultaneously freezes them.

[0005] With these ice cream machines, the produced ice cream is usually dispensed in a strand, for example with a round or star-shaped cross-section. Description of the invention

[0006] The inventor recognized that ice cream makers for home use are limited in their cooling and drive components for cost reasons. For example, the ice cream maker described in DE 20 2023 103 339 U1 does not allow for easy variation in the amount of ice cream dispensed, as the drive unit does not provide the necessary power or power variability.

[0007] When producing spaghetti-shaped ice cream, the pressure conditions in the ice cream mixture change in the area of ​​the dispensing opening of the ice cream machine.

[0008] The inventor therefore set himself the task of equipping a machine for ice production in the area of ​​home application in such a way that it can optionally dispense ice cream in spaghetti form in addition to strand-shaped ice cream dispensing.

[0009] This problem is solved by an attachment for the production of spaghetti ice cream for an ice cream machine according to claim 1.

[0010] The inventor therefore proposes to improve an attachment for the production of spaghetti ice cream for an ice cream machine, comprising at least a rotationally symmetrical hollow body, which has a closure on one side for detachably connecting the attachment to an ice cream dispensing point of the ice cream machine and has an attachment base on the side opposite the closure, wherein several dispensing openings are arranged in the attachment base from which ice cream is expressed in spaghetti form, in such a way that a first cross-sectional area in the area of ​​the closure is smaller than a second cross-sectional area in the area of ​​the attachment base.

[0011] The conical widening of the attachment from the closure area to the base acts as a diffuser. The ice cream mass flowing within the attachment is slowed down. This allows the ice cream machine's drive power to continuously produce spaghetti-like strands of ice cream.

[0012] It is advantageous if the first cross-sectional area in the area of ​​the closure increases continuously until it reaches the second cross-sectional area in the area of ​​the base plate. This specific change in cross-section can slow down the flow of the ice mass and positively influence the pressure within the ice mass.

[0013] Inside the rotating body, a support can be formed in the area of ​​the closure. A seal can be supported against this support. The seal at the ice machine's dispensing area prevents leaks and pressure drops in the ice mixture.

[0014] The seal can be made at least partially of silicone and may have chamfers or rounded edges in the direction of ice flow. The advantages of silicone seals lie in their high resistance to temperature, chemicals, and weathering. The flexibility of silicone makes it particularly suitable for use in the food and medical industries. These positive material properties of silicone, as well as its durability, are maintained over a long period.

[0015] It is advantageous if the dispensing openings have beveled or rounded surfaces at one beginning and / or one end. This ensures that the spaghetti-like ice cream mixture is dispensed true to its shape.

[0016] One variant of the invention provides that the base of the attachment is permanently bonded to the rotating body of the attachment via ultrasonic welding. This allows partial components of the rotating body of the attachment to be manufactured first using injection molding and then assembled as a single, finished part.

[0017] The attachment is preferably made of a thermoplastic material, ideally polycarbonate. Polycarbonate, as a thermoplastic, can be easily and effectively welded using ultrasound. Furthermore, polycarbonate (PC) has high impact resistance, making it virtually unbreakable, and good thermal insulation due to its multi-rib structure.

[0018] The closure can be a positive-locking type, preferably a bayonet fitting or a threaded fitting. The bayonet fitting, in particular, offers quick and easy handling thanks to its twist-and-plug motion, providing a very secure and reliable connection that does not give way even under mechanical shock.

[0019] The invention presented here will now be described with reference to the Fig. 1 to 4 described. The Fig. Figure 1 shows a perspective view of an attachment 1 for producing spaghetti ice cream for an ice cream machine. The attachment 1 consists of a rotationally symmetrical hollow body with a closure 2 on one side. This closure 2 allows the attachment 1 to be detachably connected to an ice cream machine. On the side opposite the closure 2, the attachment 1 has a base 4. According to the invention, a first cross-sectional area in the region of the closure 2 is smaller than a second cross-sectional area in the region of the base 4, resulting in a conically shaped attachment wall 3. The Fig. Figure 2 shows an oblique view from below of the attachment 1, looking towards the base 4. In this view, the dispensing openings 5 ​​are visible, from which the spaghetti ice cream flows out in threads. Beveled or rounded surfaces are visible at the end of the dispensing openings 5. This allows the spaghetti-like strands of ice cream to be dispensed true to shape without breaking. The Fig. Figure 3 shows a vertical view from below of the attachment 1, looking towards the base 4. In this view, the dispensing openings 5 ​​are visible, from which the spaghetti ice cream flows out in a thread-like fashion. Beveled or rounded surfaces are visible at the end of the dispensing openings 5. This ensures that the spaghetti-thin ice cream is dispensed true to its shape without breaking. The Fig.Figure 4 shows a perspective view from below of an attachment 2, which is mounted on a dispensing point 8 of an existing ice cream machine. The conical shape of the attachment wall 3 is also clearly visible. Reference symbol list 1 essay 2 Closure 3 Top wall 4 Top shelf 5.
