Definitions

  • the invention relates to a grinder for cutting material of different consistency to be shredded, in particular a meat grinder, with a conveying device for transporting the material to be fed into the conveying device via a cutting device into a conveying opening, the cutting device essentially consisting of a perforated disk and one in the conveying direction in front of the perforated disk cutting knife located there.
  • a long conveying path in the conveyor device to the cutting device is advantageous.
  • the material to be cut arrives in the area of the conveying device, it is subject to a conveying pressure generated by it, and as the conveying path increases, an ever higher pressure builds up in the material to be cut, with a maximum directly in front of the perforated disk; it leads to a high shredding performance because the material to be shredded by the cutting knife with this high pressure is conveyed through the perforated disc.
  • a wolf intended for such a material to be sliced must be of a different nature: the material to be sliced may only be subjected to a short conveying path to the cutting device so that the pressure in the material to be sliced remains at a low level.
  • the path remaining in the grinder up to the conveying opening only plays a subordinate role after the processing of the material to be cut in the cutting device, because the material which is still frozen does not tend to cake and therefore cannot smear.
  • a wolf of the type described in the introduction is therefore usually only designed and usable for one of the two different types of material to be cut. Attempts have also been made to remedy this deficiency and to design a wolf so that it can be used universally; in addition there is its pressure zone - ie the conveying path in the conveying device and the subsequent cutting path in the Cutting device until the material to be cut emerges from the perforated disc - has been set to an average value which, of course, can only be inadequately adapted to the different material to be cut. Such a compromise in the design of the pressure zone can understandably not guarantee optimal treatment of differently structured material to be cut.
  • the object of the invention is therefore to design such a wolf of the type described above in such a way that it can be prepared for very different items to be cut, and in such a way that a high-quality end product can be produced from each item to be cut, of this quality otherwise can only be achieved with one device that is specially designed for the particular material to be cut and is not suitable for another.
  • the object is achieved in that a widening the conveying path of the material to be cut and easily removable and re-insertable from the wolf housing is provided in a wolf housing between the conveyor and the cutting device.
  • the pressure zone of the grinder can be optimally adapted to very different items to be cut, since different intermediate pieces can be used to ensure that the conveying path is changed in accordance with the respective items to be cut. Since the wolf otherwise remains unchanged, the perforated disk which is sunk without the intermediate piece in the wolf moves more or less in the direction of the conveying opening, thereby shortening the conveying path in the conveying direction after the perforated disk.
  • the invention can be embodied particularly simply on a wolf in which the conveying device and the cutting device are provided in alignment in the tubular wolf housing in a common axis, the cutting device by means of a threaded connection with the wolf housing on its open end face and provided with the conveying opening for the finished product Clamping bushing is axially clampable and the intermediate piece has a coaxial spacing bushing which can be inserted into the wolf housing.
  • Such a spacer bushing can be designed as an easy-to-produce rotating part, it being particularly advantageous if the spacer bushing - abutting a stop collar of the wolf housing for the cutting device - can be inserted into the wolf housing and is radially supported on its inner casing; its installation and removal is easy, so that neither specialist knowledge nor special manual dexterity is required.
  • the conveying device has a screw conveyor which, together with the cutting knife, is applied in a rotationally fixed manner on a drive shaft operated by a rotary drive.
  • the screw conveyor consists of a first screw segment which remains permanently on the drive shaft and a second, there is a screw segment belonging to the intermediate piece and easily removable together with the spacer bush, so that a corresponding delivery pressure is exerted up to the perforated disk, valid whether this is provided at the end of a long or a short funding path.
  • the screw conveyor is guided radially and securely together with the drive shaft when the first screw segment with its outer lateral surface is guided on the inner jacket of the wolf housing, which has a cylindrical cylindrical envelope, and the second screw segment with its outer jacket surface is guided on a comparable inner jacket of the spacer sleeve ; it is best if the diameter of the second screw segment is equal to or smaller than the diameter of the first, so that the spacer bush does not require a particularly drastic reduction in the wall thickness on the (surrounding) wolf housing.
  • a length compensation takes place in a simple manner in that at least one coaxial spacer ring can be inserted between the clamping bush and the perforated disk when the intermediate piece is removed from the wolf; it can easily be set up so that the clamping bush remains in the same axial assignment to the open face of the wolf housing.
  • the invention accordingly ensures, with very few additional, simply shaped and easy-to-use components, that a wolf of the type described at the outset can be used in a variety of ways and can be used practically for all items to be cut, without affecting the quality of the end product.
  • Fresh or frozen meat can be chopped just like soft or very firm cheese or the like; any material to be cut is suitable for processing in such a grinder if only the pressure Zone dimensioned accordingly and the position of the perforated disc in relation to the conveyor is made to match.
  • FIG. 2 shows an enlarged longitudinal section through FIG. 1 through the working area of the wolf for processing a relatively soft
  • a tubular wolf housing 1 according to FIG. 1, which can be connected to the other assemblies of the wolf by means of a holding flange 26, in particular with a rotary drive for a screw conveyor 3 and thus also for a housing accommodated in a drive housing Drive shaft 2, with the aid of which both a conveyor device 4 provided with a screw conveyor 3 and a cutting device 5 are driven.
  • the conveying device 4 also includes a helical groove 7 which is recessed into the inner casing 6 of the wolf housing 1 in the length of the conveying screw 3 and which enhances the conveying effect for the product.
  • the slope of the screw conveyor 3 is so directed that a material to be cut brought into the area of the conveyor 4 is transported in a conveying direction 8 which coincides with an axis 9 of the drive shaft 2 common to the wolf housing 1, the conveyor 4 and the cutting device 5.
  • the cutting device 5 consists of a cutting knife 10 which is rotationally connected to the drive shaft 2 and consists of radially directed cutting blades 12 attached to a knife hub 11 and a perforated disk 13 which is guided on the inner casing 6 in a rotational test.
  • the bearing ring 15, like the perforated disk 13 and the disk 14, is also axially displaceable in the wolf housing 1 and transmits a clamping force exerted by a clamping bush 27 to the inserted components of the wolf, which - apart from the screw conveyor 3 and the cutting knife 10 - has an axially parallel, groove-shaped groove 17 which, together with a knob on the inner jacket 6 omitted in the drawing, form a rotation lock in the usual way.
  • the clamping bush 27 is connected by means of a clamping thread 18 to the wolf housing 1 on its open end face 23 and is provided with a conveying opening 19 for the finished product.
  • the screw conveyor 3 is made in two parts - in the axial direction - and consists of a first screw segment 20 and an axially immediately adjoining second screw segment 21, which is surrounded radially and in the installed state by a spacer bushing 22 which, together with the screw segment 21, forms an intermediate piece 21, 22 which is between the first screw segment 20 and the Disk 14 inserted and can be removed again.
  • FIGS. 2, 3, illustrate two different forms of use of the wolf according to the invention.
  • the wolf is equipped with the intermediate piece 21, 22, which, extending the conveying path 8 in the conveying device 4, has displaced the cutting device 5 far in the direction of the conveying opening 19, so that the perforated disk 13 is close to the conveying opening 19th is located and the finished product leaves the grinder immediately after comminution, while on the other hand the conveying path 8 for the material to be cut is extended by the axial length 1 of the intermediate piece 21, 22.
  • the spacer bushing 22 does not necessarily have to be as long as the second screw segment 21, as is shown in FIG.
  • a spacer ring 28 which is non-rotatable on the wolf housing 1 and whose axial length 1 ′ is approximately the same as the length 1 of the intermediate piece 21, 22 serves for length compensation and has been inserted between the bearing ring 15 and the clamping bush 27. Otherwise the wolf remains unchanged.
