Description

Technical Field

[0001] The invention relates to the technical field of hoof tying production, and in particular to a hoof tying production process. Background Art

[0002] Bundled pig's trotters is a famous dish. In the production process of bundled pig's trotters, it needs to go through multiple processes such as material selection, pickling, steaming, vacuum packaging and subsequent sterilization. The commonly used sterilization method is generally high-temperature steam sterilization. Although this sterilization method has a good sterilization effect, it also has the following disadvantages:

[0003] 1. In the process of sterilization of the existing high-temperature steam sterilization device, the bound hoof is generally in a fixed state, and the side close to the steam output part is more likely to contact with the steam, while the side far away from the steam output part has a poorer contact effect with the steam, and the uniformity of sterilization needs to be improved.

[0004] 2. After steam sterilization, the bound hooves will have a relatively high temperature. In the existing method, it is generally allowed to cool naturally, which takes a long time and causes the overall production process to be longer. Therefore, we need to consider how to solve this problem. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a hoof binding production process is proposed. Compared with the prior art, the process is improved in the high-temperature sterilization, and the sterilization is combined with the cooling, which not only improves the uniformity of the high-temperature sterilization, but also improves the efficiency of the subsequent cooling.

[0008] S2. Prepare a marinade, which includes monosodium glutamate, cooking wine, soy sauce, onion powder, ginger powder, sugar and salt. Apply the marinade evenly on the pig's trotter and the sliced ​​lean meat, and marinate for 1-3 days.

[0009] S3, spreading the marinated trotter meat surface upward, placing the marinated lean meat on the flat trotter, and sealing it with a white cloth;

[0010] S4, putting the sealed pig's trotters into a cooking pot, and adding fennel, aniseed, cloves, star anise, dried chili pepper, star anise, salt, sugar, soy sauce, licorice and bay leaves, and simmering for 3-4 hours, specifically, simmering for two-thirds of the time on high heat, and then simmering for one-third of the time on low heat, to form a semi-finished product;

[0011] S5. After removing the white cloth from the semi-finished product, vacuum packaging is performed, and the bundled trotters after vacuum packaging are sent to a steam sterilization device for sterilization. The bundled trotters after sterilization in the steam sterilization device can be put into subsequent boxing processing.

[0012] Preferably, the steam sterilization device includes a shell, a plurality of bases are installed at the lower end of the shell, a disinfection chamber and a pressure storage chamber are arranged in the shell, a sealing door is installed on the front side of the disinfection chamber, a cooling groove is provided at the upper end of the shell, a sterilization mechanism is arranged in the shell, the sterilization mechanism is horizontally arranged in a net box in the disinfection chamber, a mesh cover is installed at the upper end of the net box, the left and right sides of the net box are fixedly connected with a rotating shaft, the other ends of the two rotating shafts are respectively rotatably connected to the inner wall of the disinfection chamber, an installation groove is provided in the disinfection chamber, and a steam generator is installed in the installation groove.

[0013] Preferably, the gas trigger mechanism includes a piston plate slidably connected in the pressure storage chamber, the upper end of the piston plate is elastically connected to the inner top of the pressure storage chamber through a spring, a through opening communicating with the outside is provided on the rear side of the inner top space of the pressure storage chamber, and a through opening is opened at the inner bottom of the pressure storage chamber.

[0014] Preferably, a gear is fixedly connected to one of the rotating shafts, a rack is fixedly connected to the lower end of the piston plate, and the lower end of the rack extends into the disinfection chamber and meshes with the gear.

[0015] Preferably, the inner bottom of the cooling trough is filled with water, a mesh plate is installed at the notch of the cooling trough, a rectangular groove is opened at the inner bottom of the cooling trough, semiconductor refrigeration components are installed on the left and right sides of the shell, and the cooling ends of the two semiconductor refrigeration components extend into the cooling trough, a drain port is installed on the front side of the bottom space of the cooling trough, and a manual valve is installed in the drain port.

[0016] Preferably, the top space of the disinfection chamber is connected with a connecting pipe, the other end of the connecting pipe extends into the rectangular groove and is fixedly connected with a vertical pipe, the inner bottom of the cooling groove is fixedly connected with a U-shaped connecting frame, a rotating tube is vertically penetrated on the U-shaped connecting frame, the rotating tube is a tube body with a sealed upper end and a conductive lower end, and the rotating tube is rotatably connected to the U-shaped connecting frame.

[0017] Preferably, the lower end of the rotating tube is connected to the upper end of the vertical tube via a rotating joint, and a plurality of curved tubes are fixedly connected to the outer side of the upper end of the rotating tube at equal intervals, and the plurality of curved tubes are all connected to the rotating tube.

[0018] Preferably, a normally closed solenoid valve is installed in the connecting pipe, a touch delay switch is installed on the inner top of the pressure storage chamber, the touch delay switch is electrically connected to the normally closed solenoid valve, and a conductive block that cooperates with the touch delay switch is fixedly connected to the upper end of the piston plate.

[0019] The present invention has the following beneficial effects:

[0020] 1. By adopting this production process, the tied pig's trotters are rich in nutrition, meaty but not greasy, red in color, moderately salty and sweet, rich in umami flavor and can make people salivate after chewing. At the same time, compared with the existing technology, the air-drying part and the steam sterilization part are combined, which greatly shortens the production cycle and improves the overall production efficiency.

[0021] 2. Through the cooperation of the piston plate, spring, touch delay switch and normally open solenoid valve, the piston plate can be intermittently moved up and down during the operation of the steam generator, and reciprocating motion can be performed. With the use of gear racks, the mesh box part can be continuously flipped back and forth, so that the steam can more comprehensively contact the mesh box and the hoof-binding packaging bag inside the mesh cover, thereby improving the comprehensiveness of steam sterilization.

[0022] 3. Through the use of connecting pipes, rotating joints, rotating pipes and multiple curved pipes, high-pressure gas enters the cooling trough and comes into contact with the low-temperature water in the cooling trough. The low-temperature water can quickly cool down the high-temperature gas. Most of the high-temperature gas is water vapor. After cooling, the water vapor will turn back into liquid and stay in the cooling trough, realizing the recovery of water vapor, reducing the waste of water resources, and can be used again later.

[0023] 4. When the curved pipe part rotates, it will disturb the water in the cooling trough, making the water temperature in the cooling trough more uniform, ensuring the cooling effect on water vapor and ultimately improving water recovery.

[0024] 5. The rotation of the curved tube part will make the fan blade part rotate, that is, the fan blade rotates for a period of time after a period of time, generating an upward gas flow. Due to the low-temperature water at the bottom of the cooling trough, the temperature in the cooling trough is relatively low, so the low-temperature gas flows up and down. When passing through the mesh plate, the packaged bundles of hooves in the cooling state can be quickly cooled down, which greatly improves the cooling speed, thereby improving the actual production efficiency compared with the existing technology.

[0025] To sum up, in the production process of tying pig trotters, especially in the sterilization process, the present invention utilizes the intermittent release of high-pressure gas generated by steam sterilization, which can improve the comprehensiveness of steam sterilization without the need for an external driving source, and can also convert water vapor in the released gas back into liquid, so that it can be recycled and reused, which is more environmentally friendly; in addition, the fan blades are arranged to rotate for a certain period of time after a period of time, generating an upward gas flow, and when the airflow passes through the mesh plate, the packaged pig trotters in a cooling state can be quickly cooled, thereby accelerating the cooling speed, shortening the processing time, and improving production efficiency.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0043] Among them, it also includes a gas trigger mechanism, which includes a piston plate 11 slidably connected in the pressure storage chamber 9, the upper end of the piston plate 11 is elastically connected to the inner top of the pressure storage chamber 9 through a spring 12, and a through port communicating with the outside is provided at the rear side of the inner top space of the pressure storage chamber 9, and a through port 10 is provided at the inner bottom of the pressure storage chamber 9, a gear 26 is fixedly connected to one of the rotating shafts 17, and a rack 27 is fixedly connected to the lower end of the piston plate 11, and the lower end of the rack 27 extends into the disinfection chamber 8 and meshes with the gear 26;

[0044] The inner bottom of the airing and cooling groove 6 is filled with water, a mesh plate 7 is installed at the notch of the airing and cooling groove 6, a rectangular groove 19 is provided at the inner bottom of the airing and cooling groove 6, semiconductor refrigeration components 4 are installed on both sides of the left and right sides of the shell 1, and the semiconductor refrigeration components 4 are composed of semiconductor refrigeration sheets and heat dissipation fans. The cooling ends of the two semiconductor refrigeration components 4 extend into the airing and cooling groove 6, and a drain port 5 is installed at the front side of the bottom space of the airing and cooling groove 6, and a manual valve is installed in the drain port 5;

[0045] Among them, the top space of the disinfection chamber 8 is connected with a connecting pipe 18, the other end of the connecting pipe 18 extends into the rectangular groove 19 and is fixedly connected with a vertical pipe 25, the inner bottom of the airing and cooling groove 6 is fixedly connected with a U-shaped connecting frame 20, and a rotating tube 24 is vertically penetrated on the U-shaped connecting frame 20, the rotating tube 24 is a tube body with an upper end sealed and a lower end conductive, the rotating tube 24 is rotatably connected to the U-shaped connecting frame 20, the lower end of the rotating tube 24 is connected to the upper end of the vertical pipe 25 through a rotating joint 23, and a plurality of curved tubes 28 are fixedly connected to the outer side of the upper end of the rotating tube 24 at equal intervals, and the plurality of curved tubes 28 are all connected to the rotating tube 24, and the bending directions of the plurality of curved tubes 28 are as follows Figure 5 As shown, after the multiple curved tubes 28 eject high-speed airflow, they are subjected to a reaction force, and the whole formed by the multiple curved tubes 28 and the rotating tube 24 will rotate counterclockwise from a top-down perspective. A normally closed solenoid valve and a check valve are installed in the connecting tube 18. The check valve can prevent the liquid from flowing back into the disinfection chamber 8. A touch delay switch 13 is installed on the inner top of the pressure storage chamber 9. The touch delay switch 13 is electrically connected to the normally closed solenoid valve. After the touch delay switch 13 is energized, the normally closed solenoid valve can be energized for two minutes. The upper end of the piston plate 11 is fixedly connected to a conductive block 14 that cooperates with the touch delay switch 13, and the conductive block 14 is grounded.

[0046] In the present invention, during normal use, after the pig trotters are pickled, stewed and vacuum-packed, the sealing door 3 is opened, and then the packed pig trotters are evenly placed on the inner bottom of the net box 21, and then the net cover 22 is installed. The net cover 22 can limit the position of the pig trotters through the limiting and squeezing effect of the net cover 22 to prevent the pig trotters from sliding in the net box 21;

[0047] Then, the sealing door 3 is closed, and then the semiconductor refrigeration element 4 and the steam generator 16 are started. After the semiconductor refrigeration element 4 is started, the water in the airing and cooling tank 6 will be cooled down, so that the water in the airing and cooling tank 6 is low-temperature water. After the steam generator 16 is turned on, the water will evaporate through the high temperature to generate water vapor. The water vapor moves upward and contacts with the packaged pig trotters. In this way, high-temperature sterilization of the pig trotters can be achieved. As the high-temperature water vapor continues to increase, the gas pressure in the disinfection chamber 8 gradually increases, so that the piston plate 11 is pushed upward by the air pressure. The piston plate 11 moves upward, and the spring 12 is compressed by the piston plate 11. The gradual upward movement of the piston plate 11 will pull the rack 27 upward. After the rack 27 moves upward, it will drive the gear 26 meshed with it to rotate, and finally realize the rotation of the corresponding rotating shaft 17. The rotation of the rotating shaft 17 can drive the whole formed by the net box 21 and the mesh cover 22 to rotate. The whole formed by the net box 21 and the mesh cover 22 will be continuously turned over with the injection of uncontrolled steam, so that the steam can more comprehensively contact the hoof bundling packaging bag inside the net box 21 and the mesh cover 22, so as to realize comprehensive steam sterilization.

[0048] When the piston plate 11 moves up to the conductive block 14 and contacts the touch delay switch 13, the normally closed solenoid valve is energized and opened, and the high-pressure gas in the disinfection chamber 8 is quickly released, and passes through the connecting pipe 18, the rotary joint 23, the rotating pipe 24 and the plurality of curved pipes 28 in sequence, and enters the air-cooling tank 6, and contacts with the low-temperature water in the air-cooling tank 6. The low-temperature water can quickly cool down the high-temperature gas. Most of the high-temperature gas is water vapor. After cooling, the water vapor will turn into liquid again and stay in the air-cooling tank 6, realizing the recovery of water vapor, reducing the waste of water resources, and can be used again later. It should be noted here that the partial rotation of the curved pipe 28 will disturb the water in the air-cooling tank 6, making the water temperature in the air-cooling tank 6 more uniform, ensuring the cooling effect on the water vapor, and finally improving the recovery rate of the water.

[0049] During the gas release process, due to the elastic action of the spring 12, the piston plate 11 will move down quickly, and drive the rack 27 to move down, and finally the quota and the gear 26 will allow the shaft 17 to rotate, so that the mesh box 21 and the mesh cover 22 form a whole rotation and return to the initial state. When the subsequent normally closed solenoid valve is energized, the connecting pipe 18 will be sealed again, thereby repeating the above action.

[0050] Example 2

[0051] Reference Figure 6The difference between this embodiment and embodiment 1 is that a rotating rod 29 is fixedly connected to the upper end of the rotating tube 24, and a plurality of fan blades 30 are evenly installed on the outer side of the upper end of the rotating rod 29. The height of the fan blades 30 is higher than the water surface. When the plurality of fan blades 30 rotate with the rotating tube 24, a gas flow from bottom to top will be generated, and a plurality of air inlets are opened on the outer wall of the middle and upper part of the cooling trough 6 for replenishing gas.

[0052] Each time the gas is released, the rotation of the rotating tube 24 will also cause the multiple fan blades 30 to rotate, generating a gas flow from bottom to top. The gas flow will generate an upward airflow. After a single disinfection is completed, the disinfected packaged and tied hoof bag is taken out and placed on the placement mesh plate 7, and then a new packaged and tied hoof is put into the disinfection chamber 8 to continue the disinfection work. During this disinfection process, since the gas will be released intermittently again, the fan blades 30 will also rotate for a period of time after a period of time, generating an upward gas flow. Due to the low-temperature water body at the bottom of the cooling trough 6, the temperature in the cooling trough 6 is relatively low, so the low-temperature gas flows up and down, and when passing through the placement mesh plate 7, the packaged and tied hoof in the cooling state can be quickly cooled down, so that its cooling speed is greatly improved, thereby improving the actual production efficiency relative to the prior art.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
