[0027] Embodiment 1:

[0028] A specific implementation mode of the present invention: a protruding structure 25 cooperating with the blade groove 23 is disposed on the side wall of the blade body 18 , and the protruding structure 25 separates the blade body 18 and the blade groove 23 to form a cavity.

[0032] Furthermore, the through hole 22 is rectangular, and the side edges of the through hole 22 along the vertical direction are arranged in an arc shape.

[0033] A sausage enema machine includes a sausage enema machine body 2, a sausage enema machine vane pump 5 is arranged inside the sausage enema machine body 2, a feed hopper 1 is connected to the top of the sausage enema machine body 2, the feed hopper 1 is connected to the sausage enema machine vane pump 5, the vane pump includes a pump body 11, a pump cover 12, a coupling and a motor, and also includes the sausage enema machine vane wheel blade 15.

[0034] Furthermore, a slot 20 is provided on the upper end surface of the pump body 11, and a blade wheel is provided at the eccentric position of the slot 20 through plug-in rotation connection.

[0035] The impeller includes an impeller body 16 and a connecting shaft 17. The connecting shaft 17 is connected to the output shaft of the motor through a coupling. The cross section of the impeller body 16 is set to be concave. The impeller body 16 is embedded in the groove 20. The stator 13 is set at an eccentric position in the groove 14 of the impeller body 16. The stator 13 is fixed to the pump cover 12 by plugging. The pump cover 12 is fixed to the pump body 11. The side wall of the impeller body 16 is provided with a blade groove 23 for plugging the impeller blade 15 of the sausage enema machine.

[0036] Furthermore, a positioning groove which is snap-connected to the slot 20 is provided on the lower end surface of the impeller body 16 .

[0037] Furthermore, the side wall of the blade wheel body 16 and the inner wall of the slot 20 enclose an eccentric filling channel 21 , and the sausage stuffer blade wheel blade 15 can slide in the blade slot 23 under the pressure of the side wall of the eccentric filling channel 21 and the stator 13 .

[0038] Furthermore, a feed port 19 and a discharge port 3 are provided in the eccentric filling channel 21 , and a vacuum port 4 communicating with the eccentric filling channel 21 is provided on the outer side of the eccentric filling channel 21 .

[0039] It should be noted that the present invention is a sausage enema machine, which is different from the sausage enema machine in that the blade wheel of the sausage enema machine is different.

[0040] One side of the blade body 18 is uniformly provided with through holes 22 in the horizontal and vertical directions. The through holes 22 are rectangular, circular or elliptical.

[0041] When doing specific work,

[0042] The only difference from the prior art is the sausage stuffer blade wheel blade, which includes a blade body 18 ; the blade body 18 is configured as a block structure with a rectangular cross section, and a protrusion structure 25 that cooperates with the blade groove 23 is provided on the side wall of the blade body 18 .

[0043] That is, compared with the prior art sausage enema blade wheel blade, the sausage enema blade wheel blade of the present invention has a protruding structure 25 on the side wall of the blade body 18 that matches the blade groove 23, so that the fit between the blade and the impeller can be reduced, so that there is a gap between the blade and the impeller;

[0044] One side of the blade body 18 is uniformly provided with through holes 22 in the horizontal and vertical directions, and the through holes 22 are in a comb shape, which can accelerate the production of sausages with tiger-skin patterns, and the sausages have tiger-skin patterns in appearance;

[0045] The applicant infers that the working principle of the above effect may be due to:

[0046] 1. A protruding structure 25 that cooperates with the blade groove 23 is provided on the side wall of the blade body 18. When the protruding structure 25 cooperates with the blade groove 23, the fit between the blade and the impeller can be reduced, so that there is a gap between the blade and the impeller;

[0047] When the eccentric filling channel 21 is provided with a feed port 19 and a discharge port 3, the blade wheel is connected to the output shaft of the motor through a coupling, the minced and seasoned meat is added from the feed hopper 1, and a small amount of air is sucked along the side wall of the feed hopper 1 under vacuum negative pressure.

[0048] At this time, minced meat and a small amount of air are filled into the discharge port 3. As the blade wheel rotates, the blade wheel blade 15 of the sausage stuffer slides in the blade groove 23 under the pressure of the side wall of the eccentric filling channel 21 and the stator 13.

[0049] Compared with the prior art, each independent blade body 18 is separated into an independent chamber, and the negative pressure is different; it is precisely because of the existence of the gap that the groove 20 on the upper end surface of the pump body 11 is in a balanced slightly negative pressure state.

[0050] The eccentric filling channel 21 gradually narrows along the feed inlet 19 toward the discharge port 3, while the gap between the impeller and the stator 13 gradually expands. Under the extrusion of the blade body 18, a small amount of minced meat and part of the air are also squeezed into the gap between the impeller and the stator 13. This part of the minced meat can be squeezed relative to the minced meat in the eccentric filling channel 21, thereby increasing a certain emulsification effect.

[0051] The minced meat in the eccentric filling channel 21 is squeezed out through the discharge port 3 to form a meat sausage; with the further rotation of the impeller, the eccentric filling channel 21 gradually expands from the vacuum port 4 to the feed port 19, and the gap between the impeller and the stator 13 gradually shrinks. At this stage, a small amount of minced meat and part of the air squeezed into the gap between the impeller and the stator 13 are squeezed out. Since part of the minced meat has been filled into the meat sausage through the discharge port 3, as the eccentric filling channel 21 further expands from the vacuum port 4 to the feed port 19, this small amount of minced meat and part of the air will generate an instantaneous negative pressure relative to other chambers. Due to the existence of the gap, the grooves 20 on the upper end surface of the pump body 11 are in a balanced state of slight negative pressure. Then, part of the air in the gap between the impeller and the stator 13 preferentially enters the eccentric filling channel 21 at this stage through the gap and mixes with the small amount of minced meat and part of the air in the chamber.

[0052] 2. When the mixed minced meat rotates to the feed port 19 with the rotation of the blade wheel, while the fresh minced meat enters the feed port 19, a small amount of air is sucked along the side wall of the feed hopper 1 due to the vacuum effect, and contacts with the emulsified mixed minced meat remaining in the previous round, and enters the next round of pressurization.

[0053] The eccentric filling channel 21 gradually narrows along the feed port 19 toward the discharge port 3, while the gap between the impeller and the stator 13 gradually expands. Most of the mixed minced meat is squeezed out through the discharge port 3 by the extrusion of the blade body 18, and a part of it is squeezed in through the gap between the blade and the impeller. Due to the injection of fresh air, the fresh air enters the chamber between the impeller and the stator 13 before the fresh minced meat, and a small amount of minced meat also enters the chamber between the impeller and the stator 13 through the gap between the blade and the impeller, and forms a certain emulsification effect under the pressurized and extruded state. This part of the minced meat protrudes relative to the minced meat in the eccentric filling channel 21 to increase the emulsification effect.

[0054] Compared with fresh minced meat, there is always a part of emulsified minced meat that is squeezed into the chamber of the impeller and the stator 13 but not filled into the casing. After several rounds of emulsification, a part of minced meat with obvious emulsification effect will be formed. Compared with fresh minced meat, the feed inlet is above the emulsified minced meat and the discharge port is below the emulsified minced meat. This ultimately results in the minced meat filled into the casing showing the effect of one section of fresh minced meat and one section of emulsified minced meat, and the external appearance of the product is a sausage with tiger skin patterns.

[0055] In order to more intuitively demonstrate the structural advantages of the present invention, the present invention is compared with the method of equivalent replacement.

[0056] Embodiment 2:

[0057] The preparation method is the same as that of Example 1, except that: one side of the blade body 18 is evenly provided with through holes 22 in the horizontal and vertical directions, and the through holes 22 are in a comb shape;

[0058] Comparative Example 1:

[0059] According to the national utility model patent No. 200720191858.6, "A vane pump for sausage enema machine" is introduced by reference. The only difference in structure from the present invention is that a protrusion structure cooperating with the vane groove is provided on the side wall of the blade body;

[0060] Comparative Example 2:

[0061] The preparation method is the same as that in Example 1, except that: during the preparation process, the vacuum is in a low negative pressure state; the vacuum degree is -0.05 MPa;

[0062] Example 1-2 and Comparative Example 1-2 were compared according to the above steps with the same feed raw materials and the same discharging speed. The density of the sausages was measured by the drainage method at a density of 1000 kg / m³ at 4°C water and normal pressure. The results are shown in Table 1:

[0063] Table 1: Comparison of the effects of preparing sausage under different conditions

[0064]

[0065] According to the data analysis in Table 1:

[0066] Compared with Example 2, Example 1 Figure 6 It can be seen from the appearance comparison that both can produce relatively obvious tiger skin pattern sausages, and the difference between Example 2 and Example 1 is that the tiger skin pattern sausages have a larger proportion of tiger skin pattern;

[0067] Compared with Comparative Example 1, Example 1 did not produce tiger-skin sausage;

[0068] This may be because there is no gap between the blades and the impeller, so the independent cavities separated by the blades in the eccentric filling channel 21 are independent and closed, so that as the eccentric filling channel 21 gradually expands along the discharge port 3 toward the feed port 19, a larger suction force can be generated to suck the minced meat in the hopper into the feed port 19;

[0069] However, since there is no gap between the blades and the impeller, the independent cavities separated by the blades in the eccentric filling channel 21 are independent and closed.

[0070] Compared with the prior art, each independent blade body 18 is separated into an independent chamber, and the negative pressure is different; it is precisely because of the existence of the gap that the groove 20 on the upper end surface of the pump body 11 is in a balanced slightly negative pressure state.

[0071] The eccentric filling channel 21 gradually narrows along the feed inlet 19 toward the discharge port 3, while the gap between the impeller and the stator 13 gradually expands. Under the extrusion of the blade body 18, a small amount of minced meat and part of the air are also squeezed into the gap between the impeller and the stator 13. This part of the minced meat can be squeezed relative to the minced meat in the eccentric filling channel 21, thereby increasing a certain emulsification effect.

[0072] The minced meat in the eccentric filling channel 21 is squeezed out through the discharge port 3 to form a sausage. With the further rotation of the impeller, the eccentric filling channel 21 gradually expands from the vacuum port 4 to the feed port 19, and the gap between the impeller and the stator 13 gradually shrinks. At this stage, a small amount of minced meat and part of the air squeezed into the gap between the impeller and the stator 13 are squeezed out. Since part of the minced meat has been poured into the sausage through the discharge port 3, as the eccentric filling channel 21 further expands from the vacuum port 4 to the feed port 19, this small amount of minced meat and part of the air will generate an instantaneous negative pressure relative to other chambers. Due to the existence of the gap, the slots 20 on the upper end surface of the pump body 11 are in a balanced state of slight negative pressure. Then, part of the air in the gap between the impeller and the stator 13 preferentially passes through the gap to enter the eccentric filling channel 21 of this stage, and mixes with a small amount of minced meat and part of the air in the chamber. When the mixed minced meat rotates to the feed port 19 with the rotation of the impeller, while the fresh minced meat enters the feed port 19, a small amount of air is sucked along the side wall of the feed hopper 1 due to the vacuum effect, and contacts with the emulsified mixed minced meat remaining in the previous round, and enters the next round of pressurization.

[0073] The eccentric filling channel 21 gradually narrows along the feed port 19 toward the discharge port 3, while the gap between the impeller and the stator 13 gradually expands. Most of the mixed minced meat is squeezed out through the discharge port 3 by the extrusion of the blade body 18, and a part of it is squeezed in through the gap between the blade and the impeller. Due to the injection of fresh air, the fresh air enters the chamber between the impeller and the stator 13 before the fresh minced meat, and a small amount of minced meat also enters the chamber between the impeller and the stator 13 through the gap between the blade and the impeller, and forms a certain emulsification effect under the pressurized and extruded state. This part of the minced meat protrudes relative to the minced meat in the eccentric filling channel 21 to increase the emulsification effect.

[0074] Compared with fresh minced meat, there is always a part of emulsified minced meat that is squeezed into the chamber of the impeller and the stator 13 but not filled into the casing. After several rounds of emulsification, a part of minced meat with obvious emulsification effect will be formed. Compared with fresh minced meat, the feed inlet is above the emulsified minced meat and the discharge port is below the emulsified minced meat. This ultimately results in the minced meat filled into the casing showing the effect of one section of fresh minced meat and one section of emulsified minced meat, and the external appearance of the product is a sausage with tiger skin patterns.

[0075] In Example 1 and Comparative Example 2, although there is a gap between the blades and the impeller, the lack of vacuum causes insufficient direct introduction of air and does not produce sausages with tiger skin patterns.

[0076] In summary, based on the traditional vane pump sausage stuffer, the present invention unexpectedly obtains a sausage stuffer capable of producing meat sausages with tiger skin pattern simply by creatively providing a protruding structure 25 cooperating with the vane groove 23 on the side wall of the blade body 18.
