Characterized in that the container for receiving the piece of frozen food is held removably attached to the rest of the device, the positioning region can be easily cleaned separately from the rest of the device. In addition, several of these containers allow for receiving the piece of frozen food very fast changeover times, as a piece to be crushed subsequently

Frozen food can already be prepared during comminution of another piece of frozen goods to the extent that it is transferred to the container and after crushing the first piece of frozen food only the containers for receiving the piece of frozen food must be replaced on the device to comminution with the subsequent piece Frozen food to continue.

The pieces of frozen food can each have a size of a portion, so that the pieces are prepared, for example, after receipt of orders and without unnecessary changeover times, such as the exchange only partially crushed pieces of frozen food in conventional devices can be processed. Also, a uniform size of the portions is guaranteed. The container has a further development to a size that is adapted to a piece of frozen food, so that the piece of frozen food can not slip in the container.

The container for receiving the piece of frozen food is advantageously formed from a side wall limiting the container lateral wall and a bottom part, so that the container has only an upper opening to one side. About the opening can then be placed in the container to be arranged piece of frozen food and the head part of the punch in the

Positioning be pushed into it to push the piece of frozen food in the direction of the scraper. The scraper is according to a advantageous embodiment arranged in the bottom part of the container, wherein the jacket wall is a splash guard for shredding possibly flying around flakes, pieces or flakes of frozen food, which does not reach the catchment area but are pushed away laterally.

Furthermore, the scraping device itself comprises at least one blade, wherein according to alternative embodiments, more than one blade may be provided. This blade is fixedly arranged, in particular fixedly arranged in the bottom part of the container for receiving the piece of frozen food. When crushing the piece of frozen food is then formed by the as a holding means

Head part of the punch, which is moved relative to the scraper, entrained and guided over the fixed blade, wherein the piece of frozen goods with the head part preferably in a rotational movement is displaceable, in particular a concentric to a central axis of the punch rotational movement is displaceable.

In a further embodiment, the blade can also be shaped differently in order to produce a specific structure of the snow ice. In particular, a device can also be assigned a plurality of detachable containers for receiving the piece of frozen food, which have different blades or a different number of blades and are interchangeable.

According to an alternative embodiment, the scraper device can by a slotted disc, in particular insert disc, with at least one

Breaking edge be formed. This slotted disc, having at least one slot through which the discs are preferably divided into two halves, can be easily inserted or inserted into the bottom part, wherein the bottom part then has an opening which is bounded by a support edge for the slotted disc , The breaking edge is in a further embodiment of

Scraper arranged directly on the slot in the slotted disc, in particular at least one edge of the slot the Breaking edge forms. Frozen food scraped off the break-away edge of the piece of frozen food then falls through the slot and the opening in the bottom part below the slotted disk into the catchment area of the device. According to a further development of the breaking edge, it is provided that it protrudes from a bottom plane of the container formed by the disc, in particular protrudes into the container interior.

In order to prevent the slotted disc is placed together with the head portion of the punch and a piece of frozen food held on the head part during the scraping of the frozen material in a rotational movement, can be provided both on the slotted disc and on the support edge positioning sections that the slotted Keep disc in a predetermined position, in particular in a predetermined position to the container and the rest of the device hold. Preferably, the positioning sections are provided by flattened areas on the outer circumference of the disc and corresponding

Regions of the bottom part formed.

The insertion of the slotted disc in the container can be done in a simple manner by the container is composed in two parts of a Mantelwandungsteil and a bottom part. The slotted disc of the scraper is then clamped between the Mantelwandungsteil and the bottom part such that a secure hold is given. The jacket wall part and the bottom part can then be connected to each other according to a development with a bayonet lock.

The attachment of the removable container for receiving the piece of frozen food to the device is carried out according to a preferred embodiment by the container for receiving the piece of frozen food is supported on two receiving pins, in particular by the container to the receiving pins matching recesses in which the recording pins at the device attached container are pushed. By a formed between the device and the container for receiving the piece of frozen food contact protection also the correct fit of the preferred deferred container can be ensured so that, in particular when operating the device, the stamp and the container with the piece of frozen food aligned in the intended manner to each other are and

Damage to the device are easily avoided. In a further embodiment, the contact securing a reed contact or a locking pin, against which the container is pressed on the device to be. In order to be able to safely carry the piece of frozen food during comminution on the rotating head part, it is further provided that drivers projecting on the head part in the direction of the positioning region can be formed. In addition to a frictional connection can thus be made during the crushing between the head part formed as a holding means and the piece of frozen food and a frictional connection.

The displacement of the head part in the direction of the scraping device takes place via a defined path length, wherein at least one end position, in particular a lower end position, of the head part according to a further embodiment, at least one end contact is assigned. This ensures that the stamp after complete crushing of the piece of frozen food is not pushed further in the direction of the scraper, so that damage to the stamp or the container or the stamp and the container are avoided. Upon reaching the end contact can then advantageously be an automatic shutdown of the device or the stamp is automatically in his

Initial situation back.

Furthermore, the stamp can be assigned at least one slip clutch. By such a slip clutch is achieved that damage to the device, in particular of the stamp, are avoided due to excessive loads, for example, in a wedging of the frozen food in the container during scraping. This slip clutch can after a Continuing to be arranged to the stamp, that the components are arranged in the longitudinal direction of the punch and are integrated within a concentric with the longitudinal axis aligned sleeve. This allows a cost-effective and space-saving arrangement of the slip clutch on the one hand. Preferably, the punch is composed of an upper part and a lower part, wherein the slip clutch is formed between these two parts of the punch.

Particularly suitable as a drive of the punch, both in the direction of displacement and in the direction of the rotational movement of the head part of the punch, is a

Belt drive, whereby the introduced via the belt drive in the punch forces are divided accordingly. The belt drive preferably engages the lower, the container for the piece of frozen food facing part of the punch. Lower part and belt drive act together via a groove in which a pulley of the belt drive is guided. In order to achieve in addition to the rotational movement of the punch and a propulsion in the direction of the container for the piece of frozen food, the upper part of the punch may have a spindle drive. The arranged between the upper part and the lower part slip clutch ensures that at a certain value exceeding resistance during the crushing of the piece of frozen the lower part slips relative to the upper part, so that the propulsion of the spindle drive not to the lower part of the punch is passed on. In a simple manner, the slip clutch can be formed by a spring part arranged between the lower part and the upper part, which measures the lower part with a predetermined force from the upper part in FIG

Pressing away direction of the container.

According to a further development, a turntable can be arranged in the catchment area, on which a collecting vessel can be arranged. The turntable allows the receptacle to be rotated during the chopping of the piece of frozen food to ensure a more even stratification of the flakes or flakes separated from the piece of frozen food appealing appearance of the then ready to serve dessert. Advantageously, the turntable in this case has a drive which is coupled to the drive of the head part of the punch such that the two drives can be actuated in a further embodiment via a common switch, in particular a single common switch.

This switch can be in a further embodiment, a lever over which the speed of the head part and thus the speed of the guided over the scraper piece of frozen food and the rotational speed of the turntable could be varied depending on the position in which the lever is moved and whether a

Turntable is provided. The further the lever is pivoted out of its starting position, the higher is then, for example, the respective rotational speed of the head part or of the head part and turntable, the head part and turntable preferably having different speeds. So that errors in the handling of the device are reliably avoided, the lever can also be designed so that it is blocked in incorrectly inserted container for receiving the piece of frozen food on the contact fuse and upon reaching an end position of the punch no further propulsion of this in the direction of Scraper causes.

Furthermore, the stamp can be performed up to the container for receiving the piece of frozen food in a stamp outwardly shielding the sleeve. This sleeve extends in a further embodiment to the upper opening of the container, wherein the sleeve is aligned with the lateral jacket wall of the correctly attached to the device container, so that the

Stamp on the positioning region facing the end of the sleeve when crushing the piece of frozen food from the sleeve is inserted directly transiently into the container. In a further embodiment, the head part of the stamp has an only slightly smaller outer diameter than the inner diameter of the sleeve and the outer wall of the container. For better handling of the container for receiving the piece of frozen food, especially when inserted into the device and during cleaning, this may have a handle. In order to clean the head part and possibly the sleeve in a simple manner, these can be removable as well as the container for receiving the piece of frozen food from the rest of the device, so that in particular all with the product, that is the frozen food, coming into contact areas of Device are easily cleaned. Accordingly, the turntable or an optionally provided drip pan can be constructed in the collecting area, wherein the collecting vessel can also be simply placed on a grate or the like in devices without turntable.
