Described annular lip (18) as Fig. 1 through boring so that the hole (32) that the interior thorax of separated permission cylindrical part (12) is connected with the zone (28) of expansion along the edge in a large number to be provided.
Extruding jet pipe recited above is suitable for disclosed the sort of stuffing horn in Fig. 2-4 record among the EP-0024790A.Described stuffing horn (40) has upstream extremity (41), and downstream (42) and be made up of two coaxial pipe in fact; Inner tube (44) and exterior tube (46).Inner tube (44) ends at its upstream extremity that the inlet (50) that is suitable for being connected with the sarcenchyma of suitable pumping is located.For example, inlet (50) can pass through mechanical meat pump (not showing) and be connected to funnel (also not showing).Described funnel can be used such as any suitable squeezable sarcenchyma of lean meat or the meat (extended meat) through extending and supply with.Can use animal, fowl or the flesh of fish, but inlet (50) is supplied with taking off the whole muscle turkey meat of bone in a preferred embodiment.
Described extreme outer duct (46) is connected with the manifold (52) of arranging inner tube inlet (50) downstream at its upstream end.Described manifold (52) comprises annular wall (54) and radial extent mouth (56) at its upstream end, the suitable activity that is connected to suitable pumping meat or fat emulsion of this mouthful.As disclosed among the EP-0024790A, this elongation mouthful (56) can for example be connected to funnel by the suitable mechanical pump, and described meat wastes or fat emulsion can comprise fibrous lean meat or fat granule and emulsifying agent.Described meat or fat emulsion can selectively add the stabilizing agent that is included in kind known in the state of the art.
Described penetralia pipe (44) runs through the centre bore that is limited by annular wall (54), and the sealing of O-ring is provided betwixt.Therefore this annular wall (54) is used for supporting the penetralia pipe (44) that coaxial relation is arranged with extreme outer duct (46) at its upstream end.The downstream of manifold (52), inner tube (44) by a large amount of, four separation dividing plates (48) along the edge are separated with exterior tube (46) in this case.Each dividing plate comprises typically from the stainless steel rectangular pieces of thin slice cutting-out and the outer surface that is welded to inner tube (44).The orientation that each dividing plate is shown in the figure is so that slicer board inserts the center longitudinal axis of stuffing horn (40).
Inner tube (44) limits the central tube that meat can be provided like this, and inside and outside pipe (44,46) limits a circulating line that meat or fat emulsion can be provided between them.
The downstream (42) of stuffing horn (40) can be installed in the interior thorax (14) of extruding jet pipe, makes the downstream of exterior tube (46) be abuttingly reposed against on the flange (18).From Fig. 1 and 2 as can be seen, the downstream of inner tube (44) is externally managed (46) and is stretched out, and the external diameter that has is so that comfortable installation in its funnel-like part in main part (10) (20).Inside and outside pipe (44 by stuffing horn, 46) circulating line of Xian Dinging can be communicated with by hole (32) with extended space (28), is limited the central tube that obtains by inner tube (44) simultaneously and can use the inner space that is limited by cylindrical wall (16) to be communicated with.Like this, the sarcenchyma of the central tube pumping by stuffing horn withdraws from the downstream end of penetralia pipe (44) and enters the central space that the cylindrical wall (16) by main part (10) limits, simultaneously along by inside and outside pipe (44,46) meat of the annular space pumping of Xian Dinging or fat emulsion enter extended space (28) by hole (32), and enter the narrower circulating line between cylindrical wall (16) and ring (30) then.This sarcenchyma and meat or fat emulsion are then from pushing the jet pipe outflow and can obtaining the soft plastic casing of disclosed the sort of rough (rouched) that can provide around extreme outer duct (46) downstream of described manifold (52) of EP-0024790A.
The co-extrusion pressure that sarcenchyma and fat or meat waste therefore form as among Fig. 5 with the food through co-extrusion pressure (100) of cross section demonstration, described product comprises that the core of sarcenchyma (102) and fat or meat waste the skin of (104).Disclosed as EP-0024790A, this product can boiling in casing (106), and this casing can be removed then and this product is cut into pieces.Perhaps, this extrudate can be cut into the moderate-length part of baking in traditional baking oven subsequently still in casing the time, removes casing after boiling.
Recognize when meat or fat emulsion along at inside and outside pipe (44, when the circulating line 46) flows, it carefully cuts the dividing plate (48) of mixing fiber in the meat stuffing by tabular being tending towards to flow to parallel direction orientation, and obtains the fiber that longitudinal region should the zone in the meat stuffing downstream and use up to mix carefully cutting of dividing plate.When entering expansion space (28) by hole (32), the constricted flow of meat or fat emulsion and sizable mixing takes place.It is believed that this mixing has the nondirectional effect of fiber in meat or fat emulsion, therefore improve the uniformity of fat emulsion layer (104).To see from Fig. 1 in the flow path in the meat of expansion space (28) or fat emulsion downstream, not occurring further hindering, and therefore when their fiber maintenance non-directionals when another end of jet pipe is squeezed.Therefore this expansion space (28) constitutes " vortex cavity " that is used for meat or fat emulsion, and the non-directional effect on fiber since the result of slowing down be considered in order to increase the bonding force of fiber.Found to make like this that the meat or the fat emulsion layer (104) of the product through pushing reduces along the trend that the direction of extrusion divides during boiling processing.Think that also the non-directional of this fiber can increase the bonding force of meat or fat emulsion layer and sarcenchyma core (102), therefore the trend of meat or fat emulsion layer and the layering of sarcenchyma core reduces after boiling.
