Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a salt water injection machine for pickling food meat. Background Art

[0002] In the field of modern food processing, meat pickling is a core process to enhance the flavor characteristics of meat products, optimize color performance and extend the shelf life of products. In order to achieve uniform penetration of pickling liquid (such as brine, spice solution, etc.) inside the meat, brine injection technology has been widely used. Traditional brine injection machines generally adopt a single-sided injection strategy, that is, the pickling liquid is injected only from one side of the meat. However, since the injection is limited to one side, it is difficult for the pickling liquid to spread evenly throughout the meat. Especially for thicker meat, the pickling effect in the central area is often unsatisfactory, resulting in the phenomenon of excessively high salt concentration in the outer layer and weak flavor in the inner layer. In addition, the single-sided injection mode requires a relatively long time to ensure sufficient penetration of the pickling liquid, which not only significantly reduces production efficiency, but may also damage the meat tissue structure due to long-term processing, thereby affecting the texture and taste experience of the final product. And during long-term use, the injection needle is easily blocked by the accumulation of impurities such as meat scraps and fat, affecting the injection effect. Summary of the invention

The sleeve 5 includes a fixed portion 51 fixed on the first injection needle seat 33 and the second injection needle seat 23. The fixed portion 51 is connected to the movable portion 52 through a first spring 53. The movable portion 52 extends out of or retracts into the fixed portion 51 to cover or expose the injection needle 4.

The anti-blocking rod 61 matches the injection needle 4. When the first injection needle seat 33 and the second needle seat move with the piston rod of the cylinder 31, the anti-blocking rod 61 enters or exits the injection needle 4 accordingly.

[0037] Furthermore, a mounting rod 34 is horizontally arranged on the mounting frame 3, a storage frame 35 is movably arranged on the mounting rod 34, a transmission rod 351 movably connected to the first connecting rod 321 is arranged on the storage frame 35, and the storage frame 35 moves along the setting direction of the mounting rod 34 as the lower pressure plate 32 moves.

[0038] In a specific embodiment, Figures 1 to 6As shown, the main body of a salt water injection machine for food meat pickling proposed in the present application is a cabinet 1, a support plate 2 is arranged inside the cabinet 1, and the two ends of the support plate 2 are fixed to the inner walls of the cabinet 1 on both sides. A rotating table 21 is arranged on the support plate 2, and a motor 211 for driving the rotating table 21 to rotate is also arranged inside the cabinet 1. Among them, a rotating disk 11 is arranged on the upper surface of the cabinet 1, and the rotating disk 11 is installed on the top of the rotating table 21. When the motor 211 drives the rotating table 21 to rotate, the rotating disk 11 rotates together. A mounting frame 3 is also arranged on the upper surface of the cabinet 1, and a first mounting plate 6 is arranged on the top of the mounting frame 3, and a cylinder 31 is fixedly arranged on the first mounting plate 6. The cylinder 31 is located above the rotating disk 11, and the piston rod of the cylinder 31 is arranged in the direction of the rotating disk 11. A lower pressing plate 32 is connected to the piston rod, and the lower pressing plate 32 is raised and lowered with the movement of the piston rod of the cylinder 31, so as to approach or move away from the rotating disk 11. A movable plate 22 is also provided inside the cabinet 1, and the movable plate 22 is located below the rotating disk 11. A first connecting rod 321 is provided at the bottom of the lower pressure plate 32, and a second connecting rod 221 is provided at the top of the movable plate 22. Racks 322 are provided on the first connecting rod 321 and the second connecting rod 221. A gear 12 is provided on the inner wall of the cabinet 1, and the racks 322 on the first connecting rod 321 and the second connecting rod 221 are both engaged with the gear 12. This design enables the driving force of the cylinder 31 to be transmitted from the lower pressure plate 32 to the movable plate 22, so that the movable plate 22 moves accordingly. Specifically, when the lower pressing plate 32 is lowered with the piston rod of the cylinder 31, the first connecting rod 321 is lowered accordingly. At this time, the rack 322 on the first connecting rod 321 is meshed with the gear 12, driving the gear 12 to rotate. Since the rack 322 on the second connecting rod 221 is also meshed with the gear 12, the second connecting rod 221 is raised with the rotation of the gear 12, so that the movable plate 22 is raised. Conversely, when the lower pressing plate 32 is raised with the piston rod of the cylinder 31, the movable rod is lowered accordingly. A first injection needle seat 33 is arranged on the lower pressing plate 32, and a second injection needle seat 23 is arranged on the movable plate 22. A plurality of injection needles 4 are arranged on the first injection needle seat 33 and the second injection needle seat 23. A water tank 13 for storing brine or other food pickling liquid is also arranged inside the cabinet 1, and a water valve 131 is arranged at the bottom of the water tank 13. A three-way pipe 14 is provided at one end of the water valve 131 away from the water tank 13, a first end of the three-way pipe 14 is connected to the water valve 131, a second end of the three-way pipe 14 is connected to the second injection needle seat 23 through a guide pipe, a connecting pipe 15 is provided at the center of the rotating disk 11, a third end of the three-way pipe 14 is connected to the first injection needle seat 33 through the connecting pipe 15, and the saline in the water tank 13 can be introduced into the first injection needle seat 33 and the second injection needle seat 23 by opening the water valve 131.When the lower pressing plate 32 descends, the first injection needle seat 33 gradually approaches the rotating disk 11 from above, and the second injection needle seat 23 gradually approaches the rotating disk 11 from below. The bottom of the rotating disk 11 is provided with a channel for the injection needle 4 on the second injection needle seat 23 to pass through, and the injection needles 4 on the first injection needle seat 33 and the second injection needle seat 23 are designed to avoid each other, so as to prevent the movement of the first injection needle seat 33 and the second injection needle seat 23 from being interfered by the injection needle 4. The food meat to be injected with food pickling liquid is placed on the rotating disk 11, and the injection needles 4 on the first injection needle seat 33 and the second injection needle seat 23 respectively inject salt water or other food pickling liquid into the food meat from above and below the food meat. The double-sided injection design allows the food pickling liquid to be more evenly spread to the whole piece of food meat, speeding up the pickling time of the food meat, improving the pickling effect, and thus improving production efficiency.

[0039] It is worth mentioning that both the first injection needle seat 33 and the second injection needle seat 23 are provided with sleeves 5 for accommodating the injection needles 4 , and the number of the sleeves 5 is the same as the number of the injection needles 4 . The sleeve 5 is composed of a movable part 52 and a fixed part 51, wherein the fixed part 51 is fixedly mounted on the first injection needle seat 33 and the second fixed needle seat, and a movable part 52 is arranged inside each fixed part 51, and the movable part 52 is connected to the fixed part 51 through the first spring 53. When the first injection needle seat 33 and the second injection needle seat 23 contact the food meat on the rotating disk 11, the movable part 52 abuts against the food meat. As the first injection needle seat 33 and the second injection needle seat 23 continue to move toward the food meat, the movable part 52 gradually retracts into the fixed part 51, the second spring 381 is compressed, and the movable part 52 no longer blocks the injection needle 4. At this time, the injection needle 4 is inserted into the food meat, and the movable part 52 is subjected to the rebound force of the second spring 381 and abuts against the surface of the food meat, thereby playing a fixing role on the food meat to ensure that the injection needle 4 can smoothly inject food pickling liquid into the food meat.

[0040] In addition, a first mounting plate 6 is provided on the mounting frame 3, the cylinder 31 is fixed on the first mounting plate 6, and a second mounting plate 25 is provided below the support plate 2. A plurality of anti-blocking rods 61 are provided on the first mounting plate 6 and the second mounting plate 25, which are the same number as the injection needles 4. The anti-blocking rod 61 on the first mounting plate 6 penetrates the first injection needle seat 33, and the anti-blocking rod 61 on the second mounting plate 25 penetrates the second injection needle seat 23, and the positions of the anti-blocking rod 61 and the injection needle 4 match. When the first injection needle seat 33 and the second injection needle seat 23 move toward the food meat on the rotating disk 11 with the piston rod of the cylinder 31, the anti-blocking rod 61 withdraws from the interior of the injection needle 4, and the injection needle 4 is inserted into the food meat. When the first injection needle seat 33 and the second injection needle seat 23 move away from the food meat on the rotating disk 11 with the piston rod of the cylinder 31, the injection needle 4 is separated from the food meat, and the anti-blocking rod 61 enters the interior of the injection needle 4. The setting of the anti-blocking rod 61 can prevent the injection needle 4 from being blocked by debris such as meat scraps or fat during the insertion of the food meat, thereby affecting the injection effect and ensuring that the processing procedure of the food meat can operate normally. In addition, a mounting rod 34 is also set on the mounting frame 3, and the mounting rod 34 is located above the rotating disk 11. A storage frame 35 is movably set on the mounting rod 34. A transmission rod 351 connected to the first connecting rod 321 of the lower pressing plate 32 is set on the storage frame 35. When the lower pressing plate 32 descends, the transmission rod 351 drives the storage frame 35 to move to the end of the mounting rod 34, thereby avoiding the descending trajectory of the first injection needle seat 33. When the lower pressing plate 32 rises, the transmission rod 351 drives the storage frame 35 to move on the mounting rod 34 to the right below the first injection needle seat 33. At this time, the anti-blocking rod 61 on the first mounting plate 6 enters the injection needle 4 of the first injection needle seat 33, so that the impurities such as meat scraps or fat in the injection needle 4 are pushed out and fall into the storage frame 35.

[0041] Furthermore, the rotating disk 11 is provided with a plurality of storage compartments for placing food meat, the rotating table 21 is provided with a plurality of sensing rods 212, and the sensing rods 212 are respectively located directly below each storage compartment, and the support plate 2 is provided with a first photoelectric switch 24 matching the sensing element, when any sensing rod 212 moves to the first photoelectric switch 24 with the rotating table 21, the first photoelectric switch 24 is triggered, and the motor 211 is turned off after the first photoelectric switch 24 is triggered.

[0042] Furthermore, a movable groove is provided on the lower pressure plate 32, a movable block 36 is provided in the movable groove, a fixed block 37 is also provided on the lower pressure plate 32, a guide rod 38 is provided on the fixed block 37, the movable block 36 is sleeved on the guide rod 38, a second spring 381 is provided on the guide rod 38, the second spring 381 is located between the fixed block 37 and the movable block 36, and the movable block 36 can move closer to or away from the fixed block 37 in the movable groove.

[0043] Further, a positioning block 361 and a sensing block 362 are provided on the movable block 36, a guide plate 16 is provided on the cabinet 1, and a second photoelectric switch 161 is provided on one side of the guide plate 16 close to the fixed block 37; The guide plate 16 is also provided with a wedge block 162 that cooperates with the positioning block 361. An annular groove 163 for the positioning block 361 to slide is formed between the wedge block 162 and the guide plate 16. The positioning block 361 slides along the annular groove 163 as the lower pressure plate 32 moves. When the lower pressure plate 32 descends, the sensing block 362 does not contact the second photoelectric switch 161. When the lower pressure plate 32 rises, the sensing block 362 contacts the second photoelectric switch 161 and triggers the second photoelectric switch 161. After the second photoelectric switch 161 is triggered, the motor 211 is turned on.

[0044] In a specific embodiment, Figures 7 to 9 As shown, a plurality of storage compartments for placing food meat are also arranged on the rotating disk 11, and a sensing rod 212 is arranged directly below each storage compartment. The sensing rod 212 is installed on the rotating table 21 and rotates therewith. A first photoelectric switch 24 is arranged on the support plate 2. When the rotating table 21 rotates, each time a sensing rod 212 moves to the position of the first photoelectric switch 24 with the rotating table 21, the first photoelectric switch 24 is triggered. A controller is arranged on the cabinet 1. After the first photoelectric switch 24 is triggered, a signal is sent to the controller, and the controller controls the motor 211 to turn off, so that the rotating table 21 stops rotating. At this time, one of the storage compartments on the rotating disk 11 is located directly below the first injection needle seat 33 and directly above the second injection needle seat 23. The start cylinder 31 can make the first injection needle seat 33 and the second injection needle seat 23 move toward the rotating disk 11 to inject the pickling liquid into the food meat in the storage compartment.

[0045] A movable groove is provided on the lower pressing plate 32, a fixed block 37 is provided at one end of the movable groove, a guide rod 38 is provided on the fixed block 37, the guide rod 38 is located just above the movable groove, a movable block 36 is provided between the guide rod 38 and the movable groove, the movable block 36 is sleeved on the guide rod 38, a second spring 381 is provided on the guide rod 38, one end of the second spring 381 is connected to the movable block 36, and the other end of the second spring 381 is connected to the fixed block 37. A positioning block 361 and a sensing block 362 are also provided on the movable block 36, a guide plate 16 is provided on the cabinet 1, a second photoelectric switch 161 is provided on the side of the guide plate 16 close to the fixed block 37, a wedge block 162 is provided on the guide plate 16, and an annular groove 163 is formed between the guide plate 16 and the wedge block 162. Specifically, when the lower pressing plate 32 descends, the positioning block 361 moves along the side of the annular groove 163 away from the second photoelectric switch 161 under the action of the wedge block 162, driving the movable block 36 to move in the movable groove away from the fixed block 37. At this time, the second spring 381 is stretched, and the sensing block 362 does not pass through the position of the second photoelectric switch 161; when the lower pressing plate 32 rises, the positioning block 361 moves along the side of the annular groove 163 close to the second photoelectric switch 161 under the action of the rebound force of the second spring 381, driving the movable block 36 to move toward the fixed block 37 in the movable groove, and the sensing block 362 passes through the position of the second photoelectric switch 161 as the lower pressing plate 32 rises. At this time, the second photoelectric switch 161 is triggered and transmits a signal to the controller, and the controller then controls the motor 211 to turn on, so that the rotating table 21 continues to rotate. After the food meat on the storage grid directly below the first injection needle seat 33 is injected, the cylinder 31 drives the lower pressing plate 32 to rise, and the second photoelectric switch 161 is triggered, causing the rotating table 21 to rotate a certain angle. When the first photoelectric switch 24 is triggered, the rotating table 21 stops rotating, and the next storage grid moves with the rotating disk 11 to directly below the first injection needle seat 33. Thus, the first injection needle seat 33 and the second injection needle seat 23 can perform injection operations on each piece of food meat on the rotating disk 11 in turn.

[0046] Furthermore, a water receiving basin 7 is provided at the bottom of the rotating disk 11 , a drainage pipe is provided at the bottom of the water receiving basin 7 , and the drainage pipe is communicated with the water tank 13 , and a filter screen is provided in the water tank 13 .

[0047] Furthermore, a liquid separation hole 41 is formed on the side wall of the injection needle 4 .

[0048] In a specific embodiment, Figure 2 , Fig.10 and Fig.11As shown, a water receiving basin 7 is also provided at the bottom of the rotating disk 11. When the first injection needle seat 33 and the second injection needle seat 23 are injecting food meat, the food pickling liquid overflowing from the first injection needle seat 33 and the second injection needle seat 23 will flow into the water receiving basin 7 through the wire mesh on the surface of the rotating disk 11. These food pickling liquids will then enter the water tank 13 through the drain pipe. A filter screen is also provided in the water tank 13. After being filtered by the filter screen, they will be sent to the first injection needle seat 33 and the second injection needle seat 23 through the water valve 131 for recycling, thereby reducing resource waste. In addition, a plurality of liquid separation holes 41 are also provided on the side wall of each injection needle 4. When the injection needle 4 injects food pickling liquid into the food meat, the food pickling liquid can be more dispersedly diffused through these liquid separation holes 41, thereby enhancing the penetration effect, so that the food pickling liquid can be more evenly distributed in various parts of the food meat.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
