Description

Technical Field

[0001] The invention relates to the technical field of meat processing, in particular to a tumbling and kneading device for meat pickling processing. Background Art

[0002] Meat pickling is a traditional food processing and storage method, and is also an important step in seasoning and tenderizing meat before cooking. The basic principle is to soak the meat in a pickling liquid containing various seasonings and auxiliary materials. Through a certain period of penetration and chemical reaction, the meat absorbs the flavor of the seasoning, improves the tenderness and flavor of the meat, and helps to retain the moisture of the meat, making it more juicy.

[0003] The tumbler is an advanced equipment used for meat pickling in food processing. It combines the principles of physical impact and vacuum technology. Through specific mechanical treatment, it accelerates the penetration of the pickling liquid into the meat and improves the tenderness and flavor of the meat. The working principle of the tumbler is based on physical impact, which causes the meat to flip up and down in the drum, collide and hit each other, achieving the effect of massage and pickling. This treatment method not only promotes the uniform distribution of the pickling liquid, but also destroys the organizational structure of the meat, making it easier for the pickling liquid to penetrate, thereby improving the water retention and yield of the meat. However, the existing tumbler equipment still has the following defects during use:

[0004] 1. The existing tumbling machine drum only rotates in one direction, and the movement trajectory of the meat in the drum is limited. The marinating liquid may not penetrate evenly into each piece of meat, resulting in uneven marinating. In order to achieve the ideal marinating effect, it may be necessary to extend the tumbling time, which in turn increases energy consumption. Moreover, the improvement of the organizational structure of the meat may not be sufficient, affecting the final meat taste and tenderness.

[0005] 2. The existing tumbling and kneading machine lacks a mechanism for directly squeezing and kneading meat when in use, which may result in the marinating liquid being unable to penetrate evenly and deeply into the meat, and the marinating process cannot be better controlled. If the seasonings, spices and other ingredients in the marinating liquid cannot fully penetrate into the meat, it will directly affect the marinating effect and the flavor of the final product. Summary of the invention

[0006] In view of the fact that the drum of the existing tumbling machine can only rotate in one direction, resulting in uneven pickling, and the tumbling machine has no effect of squeezing and massaging the meat, affecting the pickling effect and the flavor of the final product, a tumbling device for meat pickling processing is proposed.

[0007] The present application provides a tumbling and kneading device for meat pickling processing, the purpose of which is to solve the problem that the drum of the existing tumbling and kneading machine can only rotate in one direction, resulting in uneven pickling, affecting the taste and tenderness of the meat, and the tumbling and kneading machine has no mechanism for squeezing and massaging the pickled meat, so that the pickling liquid cannot penetrate the meat evenly and deeply, affecting the pickling effect and the flavor of the final product.

[0014] Furthermore, the driving assembly includes a mounting frame fixedly connected to the support plate, a driving motor fixedly connected to the mounting frame, and an output shaft of the driving motor fixedly connected to the linkage shaft.

[0015] Furthermore, the adjustment assembly includes a fixing ring rotatably connected to the sleeve, a threaded rod rotatably connected to the support plate, a connecting plate threadably sleeved on the threaded rod, and the connecting plate is fixedly connected to the fixing ring.

[0016] Further, the extrusion component includes an extrusion assembly arranged on the end cover, a transmission assembly arranged in the drum, and a reset assembly arranged on the transmission assembly;

[0017] The extrusion assembly includes a plurality of slide grooves arranged on the end cover and distributed in a ring array, sliders respectively connected to the inner sides of the plurality of slide grooves in a limited sliding manner, and extrusion plates respectively fixedly connected to the plurality of sliders.

[0018] Furthermore, the transmission assembly includes a connecting rod fixedly connected to the end cover, a reciprocating screw rotatably connected between the transmission shaft and the connecting rod, a nut threadedly sleeved on the reciprocating screw, and a plurality of support rods rotatably connected to the nut and distributed in a circular array, wherein one end of the support rod away from the nut is rotatably connected to the extrusion plate.

[0019] Furthermore, the reset assembly includes a reset chamber opened on the transmission shaft, a circular plate limitedly slidably connected in the reset chamber, a reset spring fixedly connected between the circular plate and the inner wall of the reset chamber, the circular plate fixedly connected to the reciprocating screw rod on the side away from the reset spring, an active chamber opened on the connecting rod, a reset rod slidably connected in the active chamber, and the reset rod fixedly connected to the reciprocating screw rod.

[0020] Beneficial effects of the present invention:

[0021] 1. The rotating parts drive the drum to rotate in two directions, so that the meat in the drum is fully mixed with the seasonings and spices, so that the seasonings and spices can penetrate into the meat and fully marinate the meat, thereby reducing the marinating time of the meat and reducing energy consumption. The speed of the drum can be adjusted by the gear shifting parts. At the beginning of marinating the meat, the speed of the drum can be adjusted faster to make the meat, seasonings and spices mixed quickly and evenly.

[0023] 3. The reciprocating screw and the nut move relative to each other, and the nut is stationary relative to the support rod. At this time, the support rod will no longer rotate on the nut, and the extrusion plate will no longer squeeze the meat. The reciprocating screw moves relative to the support rod, so that the reciprocating screw drives the circular plate to move into the reset chamber, squeezes the reset spring, and the reset rod moves outward in the movable chamber. When the extrusion plate is retracted, the nut moves back on the reciprocating screw, and the reset spring is reset at the same time, so that the circular plate drives the reciprocating screw to move outward of the reset chamber, thereby making the extrusion plate adaptively adjusted in the drum. When the meat piece is large, excessive extrusion can be avoided, and when the meat piece is small, it can be avoided that the meat piece is difficult to be squeezed.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] Example 1, reference Figure 1-Figure 4 , which is the first embodiment of the present invention, provides a tumbling and kneading device for meat pickling processing, including a base 1, a vacuum pump 11 fixedly connected to the top of the base 1, support plates 12 symmetrically fixedly connected to both sides of the top of the base 1, a connecting shaft 13 rotatably connected to one of the support plates 12, a frame 14 fixedly connected to the connecting shaft 13, the frame 14 is rotatably connected to the other support plate 12, a roller 15 rotatably connected to the inner side of the frame 14, a cover plate 16 installed on the roller 15, an exhaust pipe 17 fixedly installed on the top of the roller 15, a valve installed on the exhaust pipe 17, and an end cover 18 rotatably connected to the rear side of the roller 15, the end cover 18 is fixedly connected to the frame 14 , and also includes a pickling unit installed on the base 1; the pickling unit includes a rotating component installed on one side of the base 1, a gear shift component installed on the other side of the base 1, and an extrusion component installed in the drum 15, the rotating component includes a transmission assembly 2 installed on the top of the base 1, and a reversing rotation assembly 3 installed on one of the support plates 12; the transmission assembly 2 includes a transmission shaft 21 rotatably connected to the frame 14, one end of the transmission shaft 21 extends to the inner side of the drum 15 and is fixedly connected to the drum 15 and rotatably connected to the frame 14, pulleys 23 fixedly mounted on the transmission shaft 21 and the fixed shaft 22, respectively, and a belt 24 mounted between the two pulleys 23.

[0042] Specifically, the cover 16 on the drum 15 is opened, the meat to be marinated is placed in the drum 15, and then seasonings and spices are added to the drum 15, and the cover 16 is closed. One end of the hose is fixedly connected to the air inlet of the vacuum pump 11, and the other end of the hose is fixedly connected to the exhaust pipe 17. The valve is opened, and the vacuum pump 11 is started to extract the gas in the drum 15, so that a vacuum is formed in the drum 15, and the meat in the drum 15 is marinated by the marinating unit. The drum 15 is driven to rotate in two directions by the rotating component, so that the meat in the drum 15 is fully mixed with the seasonings and spices, so that the seasonings and spices can penetrate into the meat, and the meat can be fully marinated. The rotation speed of the drum 15 can be adjusted by the gear shifting component. When the meat is just being marinated, The rotation speed of the drum 15 is adjusted faster so that the meat, seasonings and spices are mixed quickly and evenly. When the meat is almost marinated, the rotation speed of the drum 15 is adjusted slower to avoid over-marinating the meat and affecting the taste in the later stage. The meat marinated in the drum 15 is squeezed and massaged by the extrusion component, which can improve the marinating effect, optimize the taste of the meat, and enhance the water retention of the meat. Through production efficiency, the fixed shaft 22 is rotated to drive one of the pulleys 23 to rotate, and under the action of the belt 24, the other pulley 23 is driven to rotate, and the transmission shaft 21 is driven to rotate, and the drum 15 is driven to rotate in one direction. Through the connecting shaft 13, the frame 14 is driven to rotate, and then the drum 15 is driven to rotate in the other direction, so that the drum 15 can rotate in two directions at the same time, thereby improving the efficiency of meat marination.

[0043] Reference Figure 4 The reversing rotation assembly 3 includes a first bevel gear 31 fixedly connected to the upper end of the support plate 12 and a second bevel gear 32 fixedly connected to the fixed shaft 22 . The first bevel gear 31 is meshedly connected with the second bevel gear 32 .

[0044] Specifically, by rotating the connecting shaft 13, the frame 14 is driven to rotate, and the fixed shaft 22 is driven to rotate, so that the second bevel gear 32 moves on the first bevel gear 31. Since the first bevel gear 31 and the second bevel gear 32 are meshed with each other, the second bevel gear 32 rotates, driving the fixed shaft 22 to rotate, so that the drum 15 can rotate in one direction and the other direction at the same time when marinating meat, thereby speeding up the process of marinating meat, making the meat more evenly marinated, and improving the meat quality more fully.

[0045] Example 2, reference Figure 5-Figure 7, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the gear shift component includes a gear shift assembly 4 installed on another support plate 12, a driving assembly 5 installed on the gear shift assembly 4, and an adjusting assembly 6 installed on the gear shift assembly 4; the gear shift assembly 4 includes a linkage shaft 41 rotatably connected to the support plate 12, a first gear 42 and a second gear 43 fixedly sleeved on the linkage shaft 41, a mounting shaft 44 rotatably connected to the support plate 12 and located at the top of the linkage shaft 41, the mounting shaft 44 is fixedly connected to the connecting shaft 13, a sleeve 45 limitedly slidingly sleeved on the mounting shaft 44, a third gear 46 and a fourth gear 47 fixedly sleeved on the sleeve 45, the first gear 42 is meshingly connected to the fourth gear 47, and the second gear 43 is meshingly connected to the third gear 46.

[0046] Specifically, the driving assembly 5 drives the gear shift assembly 4 to rotate, driving the connecting shaft 13 to rotate. The adjusting assembly 6 adjusts the gear shift assembly 4 to change the rotation speed of the connecting shaft 13 so that the meat can be marinated at an optimal time. The linkage shaft 41 rotates to drive the first gear 42 and the second gear 43 to rotate. When the first gear 42 is meshed with the fourth gear 47, the second gear 43 is not meshed with the third gear 46. At this time, since the diameter of the first gear 42 is greater than the diameter of the fourth gear 47, and the number of teeth of the first gear 42 is greater than The number of teeth of the fourth gear 47, so the rotation speed of the fourth gear 47 is faster than that of the first gear 42. At this time, the rotation speed of the connecting shaft 13 is faster. When the second gear 43 is engaged with the third gear 46, the first gear 42 is not engaged with the fourth gear 47. At this time, since the diameter of the third gear 46 is greater than the diameter of the second gear 43, and the number of teeth of the third gear 46 is more than the number of teeth of the second gear 43, the rotation speed of the third gear 46 is slower than that of the second gear 43. At this time, the rotation speed of the connecting shaft 13 decreases, so that the rotation speed of the connecting shaft 13 can be adjusted.

[0047] Reference Figure 5 The driving assembly 5 includes a mounting frame 51 fixedly connected to the support plate 12 , a driving motor 52 fixedly connected to the mounting frame 51 , and an output shaft of the driving motor 52 fixedly connected to the linkage shaft 41 .

[0048] Specifically, the drive motor 52 is supported by the mounting frame 51 , and the drive motor 52 is started to drive the linkage shaft 41 to rotate.

[0049] Reference Figure 6 and Figure 7 The adjustment assembly 6 includes a fixing ring 61 rotatably connected to the sleeve 45 , a threaded rod 62 rotatably connected to the support plate 12 , a connecting plate 63 threadedly sleeved on the threaded rod 62 , and the connecting plate 63 is fixedly connected to the fixing ring 61 .

[0050] Specifically, by rotating the threaded rod 62, under the action of the fixing ring 61, the connecting plate 63 slides on the threaded rod 62, driving the fixing ring 61 to move, so that the sleeve 45 slides on the mounting shaft 44, and then drives the third gear 46 and the fourth gear 47 to move, so that the third gear 46 is meshed with the second gear 43, the first gear 42 is not meshed with the fourth gear 47, or the first gear 42 is meshed with the fourth gear 47, and the third gear 46 is not meshed with the second gear 43, so as to adjust the speed of the connecting shaft 13. The rest of the structure is the same as that of the first embodiment.

[0051] Example 3, reference Figure 8-Figure 10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the extrusion component includes an extrusion assembly 7 installed on the end cover 18, a transmission assembly 8 installed in the roller 15, and a reset assembly 9 installed on the transmission assembly 8; the extrusion assembly 7 includes a plurality of slide grooves 71 distributed in an annular array and opened on the end cover 18, sliders 72 respectively connected to the inner sides of the plurality of slide grooves 71 in a limited sliding manner, and extrusion plates 73 respectively fixedly connected to the plurality of sliders 72.

[0052] Specifically, the conveying component 8 drives the squeezing component 7 to squeeze and massage the meat in the drum 15. The resetting component 9 allows the squeezing component 7 to be reset, thereby squeezing and loosening the meat in the drum 15 to better and more evenly marinate the meat. The slider 72 slides in the slide groove 71 to drive the squeezing plate 73 to move, so that the squeezing plate 73 squeezes the meat in the drum 15.

[0053] Reference Fig. 9 The transmission assembly 8 includes a connecting rod 81 fixedly connected to the end cover 18, a reciprocating screw rod 82 rotatably connected between the transmission shaft 21 and the connecting rod 81, a nut 83 threadedly sleeved on the reciprocating screw rod 82, and a plurality of support rods 84 rotatably connected to the nut 83 and distributed in a ring array, and the support rod 84 is rotatably connected to the extrusion plate 73 at one end away from the nut 83.

[0054] Specifically, the reciprocating screw 82 rotates to drive the nut 83 to rotate. Under the action of the slider 72 and the slide groove 71, the nut 83 moves back and forth on the reciprocating screw 82, so that the support rod 84 rotates between the nut 83 and the extrusion plate 73. Under the action of the support rod 84, the extrusion plate 73 is pushed open or closed to squeeze and massage the meat.

[0055] Reference Fig.10The reset assembly 9 includes a reset chamber 91 opened on the transmission shaft 21, a circular plate 92 limitedly slidably connected in the reset chamber 91, a reset spring 93 fixedly connected between the circular plate 92 and the inner wall of the reset chamber 91, the circular plate 92 is fixedly connected to the reciprocating screw 82 on the side away from the reset spring 93, an active chamber 94 opened on the connecting rod 81, a reset rod 95 slidably connected in the active chamber 94, and the reset rod 95 is fixedly connected to the reciprocating screw 82.

[0056] Specifically, when the piece of meat put into the drum 15 is large, after the squeezing plate 73 is pushed open by the support rod 84, due to the large piece of meat, it contacts the squeezing plate 73 too early. At this time, the nut 83 has not moved to the end of the reciprocating screw rod 82 on the reciprocating screw rod 82, but the meat has already collided with the squeezing plate 73. To prevent the squeezing plate 73 from squeezing the meat excessively and causing the meat to be crushed, the reciprocating screw rod 82 and the nut 83 will move relative to each other, and the nut 83 will be stationary relative to the support rod 84. At this time, the support rod 84 will no longer rotate on the nut 83, and the squeezing plate 73 will no longer squeeze the meat. The reciprocating screw rod 82 moves relative to the supporting rod 84, so that the reciprocating screw rod 82 drives the circular plate 92 to move into the reset chamber 91, squeezes the reset spring 93, and the reset rod 95 moves outward in the movable chamber 94. When the extrusion plate 73 is retracted, the nut 83 moves back on the reciprocating screw rod 82, and the reset spring 93 is reset at the same time, so that the circular plate 92 drives the reciprocating screw rod 82 to move outward of the reset chamber 91, and then the extrusion plate 73 is adaptively adjusted in the drum 15. When the meat piece is large, excessive extrusion can be avoided, and when the meat piece is small, it can be avoided that the meat piece is difficult to be squeezed. The rest of the structure is the same as that of Example 2.

[0057] In summary, the working principle of the present invention is as follows: when in use, the cover plate 16 is opened, the meat to be marinated is placed in the drum 15, the cover plate 16 is closed, the drum 15 is evacuated by connecting the vacuum pump 11 to the exhaust pipe 17, the driving motor 52 is started, the linkage shaft 41 is driven to rotate, and the first gear 42 and the second gear 43 are driven to rotate. When the first gear 42 is meshed with the fourth gear 47, the second gear 43 is not meshed with the third gear 46. At this time, since the diameter of the first gear 42 is larger than the diameter of the fourth gear 47, and the number of teeth of the first gear 42 is greater than the number of teeth of the fourth gear 47, the fourth gear 47 rotates faster than the first gear 42. When the connecting shaft 13 rotates faster, when the second gear 43 is meshed with the third gear 46, the first gear 42 is not meshed with the fourth gear 47. At this time, since the diameter of the third gear 46 is larger than the diameter of the second gear 43, and the number of teeth of the third gear 46 is more than the number of teeth of the second gear 43, the rotation speed of the third gear 46 is slower than the rotation speed of the second gear 43. At this time, the rotation speed of the connecting shaft 13 decreases, so that the rotation speed of the connecting shaft 13 can be adjusted, thereby driving the frame 14 to rotate, driving the fixed shaft 22 to rotate, and under the action of the first bevel gear 31 and the second bevel gear 32, driving the fixed shaft 22 to rotate, so that the drum 15 can rotate in two directions at the same time.

[0058] When the transmission shaft 21 rotates, the circular plate 92 is connected with the reset chamber 91 in a limited sliding manner, thereby driving the circular plate 92 to rotate, driving the reciprocating screw rod 82 to rotate, and driving the nut 83 to rotate. Under the action of the slider 72 and the slide groove 71, the nut 83 reciprocates on the reciprocating screw rod 82, so that the support rod 84 rotates between the nut 83 and the extrusion plate 73. Under the action of the support rod 84, the extrusion plate 73 is pushed open or retracted to squeeze and massage the meat. When the extrusion plate 73 is pressed, the reciprocating screw rod 82 and the nut 83 will move relative to each other, and the nut 83 moves relative to the support rod 84. The support rod 84 will no longer rotate on the nut 83, and the extrusion plate 73 will no longer extrude the meat. The reciprocating screw 82 moves relative to the support rod 84, so that the reciprocating screw 82 drives the circular plate 92 to move into the reset chamber 91, and squeezes the reset spring 93. The reset rod 95 moves outward in the movable chamber 94. When the extrusion plate 73 is retracted, the nut 83 moves back on the reciprocating screw 82, and the reset spring 93 is reset at the same time, so that the circular plate 92 drives the reciprocating screw 82 to move outward of the reset chamber 91, thereby making the extrusion plate 73 adaptively adjusted in the drum 15.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
