Definitions
- the invention relates to a meat grinder, which preferably designed as an angle grinder or automatic grinder and is equipped with feed and working screw.
- the DD-PS 289220 is a feed screw in meat grinders described in the recording area of the wolfend Raw material has a delivery pulse piece, which from there is a 1/4 to 1/2 worm gear, single or multiple is trained and its pitch up to 20% the screw flight height of the feed screw is formed.
- a disadvantage of all known burrows of this type is that immediately in the area of the transition from feed screw to the working screw, the handover of the wolf material from the large feed screw to the smaller working screw than from the slow-moving feeder to the fast-moving Working screw, no definite pressure build-up in the processed goods can be achieved, which negatively affects the Affects the quality of the wolf.
- this area is very poorly hygienic to control and therefore questionable from a hygienic point of view, which is also caused in particular by the fact that different raw materials and their state of health create additional problems in the transfer between the two screws.
- the raw material flows back, since the pressure force of the feed screw and the poor removal of raw material by the working screw cause the raw material to swell back into the feed hopper and is constantly squeezed.
- the object of the invention is to develop a meat grinder, designed as a straight-angle or automatic grinder, with which Area of raw material transfer from the feed screw (s) to the Working screw, depending on the type of raw material and their state forms and thus the specific transfer conditions Taking into account, a pressure build-up of the raw material is reached and the transfer point can be configured variably is.
- the solution according to the invention is characterized in that in the transfer area of the feed and working screw, in the tub or the hopper, a variable, removable and adjustable pressure chamber is provided, which corresponds to the specific operating conditions in its execution, design and arrangement changeable is trained.
- the prevailing pressure cushion in the pressure chamber results from the mass thrust, the kinetic energy, which results from the speed and geometry of the feeder and Derives worm and the preparation material, and ensures a full thrust in the pressure chamber, which is transferred to the working screw and in the Working screw is continued up to the output side provided cutting set. This increases the thrust potential for the knife system and leads to a 30% increase in performance of the meat grinder.
- the invention also includes that the pressure chamber in its Execution and arrangement can be trained differently, this depends on the prevailing operating conditions is derived and the individual elements for the pressure room be designed and arranged accordingly.
- the top cover to the feed screw housing is in their executable length designed so that through the use of so-called segments of the pressure chamber is adapted to the respective operating conditions, by the additional arrangement of segments Length of pressure chamber extended or by removing Segments the pressure chamber length is reduced.
- Pneumatic or hydraulic control systems paired with the machine control system and initiate the actuating processes during the work process and vary.
- a pressure maintenance function is assigned to the transfer point of the feed screw - work screw, which is achieved by the design of the pressure chamber in this area, since the diameter of the pressure pipe in the transfer area corresponds to the diameter of the feed screw. is adjusted so that there is a small space between the two parts.
- the pressure pipe length is also determined by the types of raw materials and their condition.
- the pressure chamber arrangement and design can also be used on meat grinders with two feed screws.
- the pressure chamber in the transfer area of feeder and working screw in its cross section, in Circumferential volume, can also be changed during the operating state is. This is achieved by using appropriate actuators, for example pneumatic cylinder, the built-in element is moved away or delivered from the transfer area.
- This control process is derived from the optimal conditions of the feeding process depending on the to be processed Raw material and the operation of the machine.
- a computer-aided control and regulation program gives the corresponding Information and impulses for control the actuators.
- feeder and working screw 1; 2 in the transfer area and the arrangement of the pressure chamber 3 are shown in principle in Figure 1.
- the housing 4 of the worm screw 2 is arranged directly on the end wall 5 of the hopper 6 and on the inside of the hopper 6 there are built-in elements 7, laterally supported against the side parts of the hopper 6, which surround the feed screw 1 above and in the inserted state Form pressure chamber 3.
- the built-in elements 7 can be entirely or individually also consist of individual sections and accordingly be arranged in the hopper 6.
- FIG. 4 which consists of a bowl-shaped base body 8, the lateral Has support and holding tabs 9 and their shell-shaped Base body 8 has a radius that is larger the feed screw is 1.
- the inner surface of the half-shell has support elements 10, that the processed goods have sufficient support and Secures dwell time in the pressure room 3, so that the necessary Axial thrust can be built up and on the material to be processed can work.
- This installation element 7 is a means Bolted segment 12, which is triangular is formed and, on the end wall 13 of the Filling funnel 6 arranged, the feed screw. 1 encloses upwards, whereby the pressure chamber 3 is formed becomes. Because of its inclined side wall 14 Feeding the material to be processed in the hopper 6 positively influences what cakes the processed goods excludes.
- the new solution can also be used in automated wolves two feed screws arranged in parallel 1.
- FIG. 3 A corresponding arrangement is shown in FIG. 3, in which designated 15 the housing of the worm 2 is.
- FIG. 5 shows in the installation element segment 11, which in its basic structure the built-in element 7 in external form and corresponds to geometric design.
- the pressure chamber 3 can be designed differently in length in order to meet the respective processing goods to give sufficient support in the pressure chamber 3 and the to secure the necessary dwell time.
- the installation elements 7 described so far are designed that they are either in part or as segments 11 lined up, used and in the guides locked in the hopper 6 and by means of clamping elements 16 be attached.
- a further embodiment of the built-in elements 7 is possible in such a way that the built-in elements 7 are designed such that they can slide into one another and are controlled via separate devices, for example hydraulic elements and a corresponding control system, in order to displace the individual segments 11. This shifting can take place during operation and can be adapted to the prevailing operating conditions.
- a major advantage of the invention is that the elements forming the pressure chamber 3 are not conventional Materials, such as gray cast iron, are made from materials with steel quality, which has a positive effect on the sliding properties affects and is also advantageous in terms of cost.
- the interchangeability is also advantageous because the Transfer point of feeder and worm screw 1; 2 exposed by removing the individual elements and thus meets the hygiene requirements future cleaning is possible.

Description
Bei weicheren Rohstoffen führt es zum Rückfließen des Rohstoffes, da durch die Druckkraft der Zubringerschnecke und die schlechte Rohstoffabnahme durch die Arbeitsschnecke der Rohstoff in den Zuführtrichter zurückquillt und ständig gequetscht wird.
Weiterhin ist die Druckrohrlänge von den Rohstoffarten und ihren Zustandsformen bestimmt.
Die Druckraumanordnung und -gestaltung kann auch an Fleischwölfen mit zwei Zubringerschnecken Anwendung finden.
- Fig. 1:
- eine Schnittdarstellung des Übergabebereiches von Zubringer- und Arbeitsschnecke
- Fig. 2:
- eine weitere Schnittdarstellung des Übergabebereiches
- Fig. 3:
- eine Stirnansicht auf den Übergabebereich
- Fig. 4:
- ein Einbauelement
- Fig. 5:
- ein Einbauelement-Segment
Dabei ist das Gehäuse 4 der Arbeitsschnecke 2 unmittelbar an der Stirnwand 5 des Einfülltrichters 6 angeordnet und an der Innenseite des Einfülltrichters 6 sind Einbauelemente 7, seitlich gegen die Seitenteile des Einfülltrichters 6 abgestützt, angeordnet, die die Zubringerschnecke 1 oberhalb umschließen und im eingesetzten Zustand den Druckraum 3 herausbilden.
Dieses Verschieben kann während des Betriebes erfolgen und kann den jeweils vorherschenden Betriebsbedingungen angepaßt werden.
