Definitions

  • the invention relates to a pressure pipe for meat grinders according to the preamble of claim 1.
  • the processed material to be minced is put into the machine via a suitable feeding device, preferably a filling funnel, and conveyed to the cutting set by the pressure and conveyor screw mounted in the pressure housing or pressure tube.
  • a suitable feeding device preferably a filling funnel
  • the pressure and conveyor screw mounted in the pressure housing or pressure tube.
  • Corresponding pressure housings are shown in the publications PS 620 312, DE-AS 1061 646 and DE-OS 3245 414.
  • the pressure and conveying screw as well as the pressure pipe of the meat grinder have the task of supporting, conveying and compressing the grinded material to a certain degree.
  • the pressure pipes are manufactured using various manufacturing methods. Pressure pipes are cast, welded or manufactured by mechanical processing. In the previously known manufacturing methods and methods, the trains in the pressure pipes are also manufactured according to the respective method, which is associated with high material and manufacturing costs.
  • the object of the invention is to develop a pressure pipe for meat grinders which meets the required flow and comminution conditions, ensures interchangeability, depending on the prevailing operating conditions, and largely excludes the abrasion of material particles and thus contamination with the material to be minced, the cleaning of the pressure pipe should be simplified and improved to ensure a high level of hygiene.
  • a pressure tube according to the invention which consists of a base body and a base body provided support system, designed as a pressure pipe insert, which is arranged exchangeably in the base body, the pressure pipe itself, provided with a special profile, which forms the trains in the pressure pipe, is interchangeable or fixed on the meat grinder.
  • the base body of the pressure pipe is manufactured in a known manner and from the usual materials, while the pressure pipe insert is made separately from the base body and made of a high-alloy steel, for example a Cr-Ni alloy steel, with other types of material also being used can. It is essential that the pressure pipe insert is designed with a surface texture that is significantly below the standard value Rz 25 without considerable additional effort in order to meet the required hygiene regulations.
  • the support system according to the invention embodied in a pressure tube insert, consisting of a cold-formed sheet-like body provided with beads, which is shaped and connected to a cylindrical body after the cold deformation, for example deep drawing, thus resulting in the pressure tube insert in which the incorporated beads are represented as trains , which is then inserted into the base body of the pressure pipe.
  • the base body of the pressure tube consists of a high-alloy steel, preferably a Cr-Ni steel, which is formed in an analogous manner from a cold-formed flat body provided with beads to form a circular base body, in which the incorporated beads are also used present themselves as trains and fulfill the corresponding functions.
  • the pressure tube insert consists of several segments, preferably two half-shells, which, when paired with one another, are used in the base body of the pressure tube, the cables already being formed in the segments / half-shells.
  • the removable support system is designed as a cage-like pressure pipe insert, in the circumferential on the side and along the pressure pipe insert, several spiral strips, attached to the end faces in end disks, are provided.
  • This support system also referred to as an open support cage, is in operative connection with the smooth walls of the base body of the pressure pipe and thus produces the active system required for crushing the wolf material.
  • the support system essentially absorbs the axially acting thrust forces, the inner wall of the base body from the pressure pipe acts as the groove base while simultaneously absorbing radially acting raw material clamping forces.
  • the support cage and the base body of the pressure pipe the overall function of the pressure pipe and the work and conveyor screw is ensured.
  • connection between the base body and the support system is designed to be positive, which on the one hand ensures that the support system is interchangeable according to the prevailing operating conditions and on the other hand ensures precise fixation and positioning within the base body.
  • the meat mincers With the invention, it is possible to equip the meat mincers with a relatively easy-to-produce base body, designed as a pressure housing or pressure tube, and then to insert them into the base body with the separately produced pressure tube insert, which can be selected according to the operating conditions according to the number, shape and size of the trains.
  • the main advantages of the invention come, namely adaptation of the train design and arrangement in the pressure pipe according to the operating conditions, the interchangeability of the pressure pipe insert, the greatest possible avoidance of abrasion of particles of the pressure pipe and thus the contamination of these particles with the wolf material, the much cheaper Manufacturing effort and a high level of hygiene to bear.
  • the support system 7 according to the invention is, as shown in FIG. 1, arranged in the base body in such a way that it can be removed or exchanged and connected to the base body 1 in a form-fitting manner, the support system 7 being designed as a pressure pipe insert 2.
  • the starting product for a pressure pipe insert 2 is a flat base element 5 made of a high-alloy stainless steel, Cr, Ti or Ni being used as alloying elements.
  • the flat base element 5 is subjected to a cold deformation, the beads 6 being shaped out, in such a way that when the pressure tube insert 2 is formed as a result of the base element 5 being assembled into a cylindrical body, the beads 6 run along the pressure tube insert 2 which has formed and the trains 3 form.
  • FIG. 2 shows a section of the flat basic element 5 and shows the obliquely molded beads 6, which then form as swirling trains 3 in the pressure pipe insert 2.
  • FIG. 4 An advantageous embodiment of the use of the pressure tube insert 2 in the base body 1 is shown in FIG. 4.
  • the pressure tube insert 2 is used in the base body 1 in such a way that a space 4 is provided between the two parts.
  • This intermediate space 4 enables additional cooling of the material to be minced, in that a cooling medium can be introduced into this intermediate space 4, which can act directly on the material, since the existing wall thickness of the pressure tube insert 2 of approximately 1-3 mm permits good heat exchange.
  • the intermediate space 4 can be used for the installation and arrangement of special functional elements.
  • sensors can be arranged which directly record the prevailing operating conditions, which are fed to a central control unit, in order then to be usable as a control and control variable for the functional process of the grinder and for controlling the grinder.
  • the pressure pipe insert 2 can also be formed from individual segments, a pressure pipe insert 2 made from two half-shells 8 most advantageously meeting the production and application-related and hygienic requirements.
  • FIG. 5 shows a half-shell 8 with the already incorporated cables 3, which, when paired with a second half-shell 8, result in the complete pressure tube insert 2 and are used in this state in the base body 1 of the pressure tube.
  • the half-shells 8 can be secured via a strip 9, which in turn engages in a groove 10 provided in the base body 1, as a result of which the entire pressure tube insert 2 is mounted in a manner that prevents it from rotating.
  • the pressure pipe insert 2 is secured against axial displacement on the inlet side by the end face of the pressure pipe insert 2 in the pressure pipe, and on the outlet side it is secured by the union nut of the meat grinder, which also braces the cutting set parts.
  • This design ensures the positive connection of the pressure pipe insert 2 and the base body 1 of the pressure pipe and enables easy removal or replacement, since no additional bracing and holding devices have to be released.
  • the existing ejection device can be used to remove the pressure pipe insert 2.
  • FIG. 6 shows a cage-like pressure pipe insert 2, which consists of spirally running spirals 11, which are delimited and fastened to the front by the disks 12; 13, and strips 11 are provided along the pressure pipe insert 2 on the outer periphery of the spirals 11, which are connected both to the disks 12, 13 and to the coils 11 and thus give the pressure tube insert 2 the required stability.
  • the pressure tube insert 2 can also be secured against rotation in the form that a groove 14 is provided in the disc 12 provided on the outlet side, which locks the entire pressure tube insert 2 in the inserted state by the feather key 15, which is also required for receiving and securing the cutting set parts .
  • a groove 14 is provided in the disc 12 provided on the outlet side, which locks the entire pressure tube insert 2 in the inserted state by the feather key 15, which is also required for receiving and securing the cutting set parts .
  • the pressure pipe insert 2 is removed in the manner already described or by simply reaching behind the disk 12 and pulling it forward.
  • both the pressure pipe insert 2 itself and the pressure pipe can be cleaned easily and comprehensively, no residual particles remain in or on the parts, 100% cleaning is possible, which in turn corresponds to the required hygiene condition.
  • a meat grinder with a pressure tube also fulfills this required hygienic condition, the base body 1 of which, as shown in FIGS. 9 and 10, consists of a high-alloy steel, in the flat starting product of which beads are incorporated and formed into a circular base body.
  • the trains 16 resulting from the shaping to form a main body 1 are arranged on the circumferential side of the main body 1 and, depending on the shaping of the beads in the flat starting material, can have different train cross-sectional shapes.
  • Trapezoidal cross-sections are shown, which are provided with curves, which has a very advantageous effect on the transport of the wolf material and at the same time has a positive effect on the cleaning process.
  • the trains 16 can run both in a straight line and in a swirling manner and end on the outlet side in front of the respective cutting set.
  • FIGS. 9 and 10 also show the assignment of a filling funnel 17 to the pressure pipe, which is of particular advantage in the case of small meat mincers.
