Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of meat food processing, and specifically, to a chopping mixer for conditioning meat food. Background Art

[0002] A chopping mixer is a common meat processing machine and is a crucial food equipment in the production process of meat products. Its working principle is that the high-speed rotating chopping knife can chop the raw meat into a delicate minced state, and at the same time, it can evenly stir other auxiliary materials. It is an indispensable meat processing machine for hotels, restaurants, canteens, meat processing plants and other units.

[0003] Chopping mixers can be divided into vacuum chopping mixers and non-vacuum chopping mixers. Among them, the vacuum chopping mixer works under negative pressure, which is not only clean and hygienic, but also because the molecular volume of the material expands, the contact area with the cutting knife increases, making the chopped particles finer and the emulsification effect better. At the same time, since the oxygen in the material is extracted, the processed finished product has a bright color, and the flavor and freshness can be maintained for a long time.

[0004] In order to improve the quality of the finished product of meat chopping, ingredients need to be added again after vacuum pumping. However, during the operation of the vacuum chopping mixer, if the operation is improper when adding ingredients after vacuum pumping, the vacuum environment will be damaged, resulting in the entry of oxygen, causing fluctuations in the meat temperature and damage to the emulsification structure, thereby affecting the quality of the finished product.

[0024] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be construed as indicating or implying relative importance.

[0025] As Figures 1 to 10 shown, it shows a chopping mixer for meat food conditioning in an embodiment of the present invention, which includes an equipment frame 1, a bearing frame 2 is installed on the side of the equipment frame 1, and also includes a vacuum cylinder 3, a material tray 5, an installation frame 6, a chopping assembly and a batching adding assembly. The vacuum cylinder 3 is fixedly installed on the bearing frame 2, a vacuum cover 4 is rotatably installed on the top of the vacuum cylinder 3, a driving member 35 is rotatably installed on the side wall of the vacuum cylinder 3, and the driving member 35 preferably adopts the form of an electric cylinder. The output end of the driving member 35 is rotatably connected to the protruding end of the vacuum cover 4. Inside the vacuum cylinder 3, a material tray 5 for placing meat food is coaxially and rotatably installed. The installation frame 6 is fixedly installed inside the vacuum cylinder 3, one end of the installation frame 6 is fixedly connected to the equipment frame 1, and the installation frame 6 is located above the material tray 5. The chopping assembly is installed on the vacuum cylinder 3 and is used for chopping the meat food in the material tray 5. The chopping assembly includes a knife cover 7, a knife shaft 8 and a scraper 10. The knife cover 7 is rotatably installed on the installation frame 6, the knife shaft 8 is rotatably installed at the end of the installation frame 6, multiple groups of blades 9 are arranged on the knife shaft 8, each group of blades 9 has several blades, and several blades 9 are arranged at equal angles in a circumferential shape with the knife shaft 8 as the center. Two scrapers 10 are fixedly installed at the bottom of the knife cover 7, and a silica gel strip 11 is detachably arranged at the position where the scraper 10 contacts the material tray 5.

[0026] Specifically, when using a chopper to process meat, first wash and cut the meat to be processed and place it on the material tray 5. Then lower the knife cover 7. Through the setting of the driving and rotating assembly, the material tray 5 and the knife shaft 8 are driven to rotate simultaneously. Through the rotation of the knife shaft 8, the knife shaft 8 drives the blade 9 to chop the meat. At the same time, through the rotation of the material tray 5, the meat on the material tray 5 is chopped. However, to avoid the meat from warming up and affecting the meat quality, the chopping time will not be too long. At this time, some salt will be added. At this time, as the chopping progresses, when the meat paste becomes viscous but not fully emulsified, ingredients need to be added to the meat, such as adding water (preferably ice water), to play a role in cooling down and improving the quality of the finished product after chopping (that is, the meat stuffing or meat paste, hereinafter referred to as meat paste for the finished product after chopping the meat). When adding liquid ingredients such as water, the water needs to be gradually added to the meat (that is, added in batches. For example, when chopping the meat, a total of 100 ml of water needs to be added. Then when adding, this 100 ml should be divided into several portions, and each portion is added after chopping for a period of time to ensure that the meat and water can be fully mixed and will not overheat). As the chopping progresses, observe the state of the meat paste. When it reaches a smooth surface and has no excess water, an appropriate amount of starch can be added to the meat paste. The addition amount of starch needs to be determined according to the quality of the meat.

[0027] After adding the starch, to optimize the emulsification structure, eliminate air bubbles, enhance the compactness, and improve the processing environment and efficiency, the meat paste also needs to be placed in a vacuum negative pressure environment. At this time, start the driving part 35. Under the action of the driving part 35, the vacuum cover 4 covers the vacuum cylinder 3. At this time, a sealed space is formed between the two. Then start the vacuum pumping assembly to pump the space into a vacuum. The degree of vacuum needs to be adjusted according to actual needs. At this time, the starch is evenly dispersed during the chopping process and combines with the protein in the meat paste to improve the water retention. As the chopping progresses, when the meat paste warms up and the viscosity increases significantly, through the setting of the ingredient adding assembly, the remaining water is added to the meat paste, and then the rotation speed is reduced for chopping until the meat paste shows a delicate luster and there are no visible particles to the naked eye, which means the meat paste is fully emulsified. During this process, through the setting of the ingredient adding assembly, seasonings (such as spices, sugar, monosodium glutamate, etc.) are added to increase the flavor, and the vacuum environment can reduce the volatilization of flavor substances. When adding seasonings, it is generally arranged before adding the remaining water for the last time to ensure that the seasonings can be fully added.

[0028] It should be added that, during the chopping process, it is necessary to first drive the knife shaft 8 to rotate, the knife shaft 8 drives the blade 9 to chop the meat, and then drive the material tray 5 to rotate. After the meat is added, slowly increase the rotation speed of the driving material tray 5, and adjust the rotation speed of the knife shaft 8 as needed. When the operation is completed, stop rotating the material tray 5 first, and then stop rotating the knife shaft 8. After use, it is necessary to clean up the residues inside and outside the chopper in time, and perform proper maintenance to extend the service life of the equipment.

[0029] It should be noted that an observation window is provided on the vacuum cover 4 to facilitate observation of the chopping state of the meat paste. In order to reduce splashing of the meat paste during chopping, the volume of the meat paste in the material tray 5 is preferably not more than 80% of the volume of the material tray 5.

[0030] The above, such as Figures 5 to 9 As shown, the ingredient adding assembly includes a powder material adding part and a liquid material adding part. The powder material adding part is installed inside the vacuum cylinder 3 and is used to add powder ingredients according to the degree of processing during the processing of meat food. The liquid material adding part is installed on the top of the equipment frame 1 and is used to add liquid ingredients according to the degree of processing. The powder material adding part includes an ingredient frame 12, a material feed frame 13, a stirring member 15, a screening frame 16 and a reciprocating member. The ingredient frame 12 is fixedly installed on the side of the mounting frame 6. A plurality of material discharge racks 13 are installed inside the material rack 12, and a first control valve 14 is fixedly installed at the discharge port at the bottom of each material discharge rack 13. A stirring member 15 is installed inside each material discharge rack 13 for stirring the ingredients in the material discharge rack 13. A screening frame 16 is slidably installed inside the material rack 12, and the bottom of the screening frame 16 is located on the upper part of the material tray 5. A screen 17 is fixedly installed in the screening frame 16. A reciprocating member is installed inside the material rack 12 for controlling the reciprocating movement of the screening frame 16.

[0031] Specifically, before vacuuming, the powdered condiments to be used are placed in the corresponding unloading rack 13. After vacuuming, when powdered materials (i.e., condiments) need to be added, the corresponding first control valve 14 is first opened to allow the condiments to fall onto the screen 17 on the screening frame 16. The pores of the screen 17 are relatively large, and a hydrophobic coating is provided on the surface of the screen 17. The condiments that fall onto the screen 17 will pass through the screen 17 and fall into the meat paste during the chopping process. At the same time, the reciprocating moving component is started to drive the screening frame 16 to reciprocate in the ingredient rack 12, so that the ingredients can fall into the meat paste for chopping and mixing. When water needs to be added, it can be completed through the design of the liquid material adding part.

[0032] When adding seasoning, in order to prevent the seasoning from agglomerating and making it difficult to add the seasoning, the corresponding stirring member 15 is started. Figure 6As shown, the stirring member 15 includes a motor and a stirring frame installed at the output end of the motor. The stirring frame is rotatably installed in the corresponding blanking frame 13. During blanking, the motor is started to drive the stirring frame to rotate, which can assist in blanking.

[0033] As described above, such as Figure 7 , Figure 8 As shown, the reciprocating movement member includes a limit frame 18, a first driving motor 19, a cylindrical cam 20 and a slider 21. The limit frame 18 is fixedly installed inside the batching rack 12. The bottom of the limit frame 18 is slidably matched with the top of the screening frame 16. The first driving motor 19 is installed inside the batching rack 12. The cylindrical cam 20 is coaxially and fixedly installed at the output end of the first driving motor 19. A slider 21 is installed on the side of the screening frame 16, and the slider 21 is slidably matched with the curved groove of the cylindrical cam 20.

[0034] Specifically, when controlling the reciprocating movement of the frame of the screen 17, the first driving motor 19 is started. The first driving motor 19 drives the cylindrical cam 20 to rotate. Through the setting of the slider 21, the frame of the screen 17 can be driven to reciprocate.

[0035] As described above, such as Figure 9 As shown, the liquid material adding part includes a storage tank 22, a feeding tank 23 and a discharging pipe 25. The storage tank 22 is fixedly installed on the top of the equipment rack 1. The feeding tank 23 is fixedly installed inside the equipment rack 1. The feeding tank 23 is communicated with the discharging port at the bottom of the storage tank 22. A second control valve 24 is fixedly installed at the communicating position between the feeding tank 23 and the discharging port at the bottom of the storage tank 22. A discharging pipe 25 is communicated between the feeding tank 23 and the batching rack 12. The position where the discharging pipe 25 is communicated with the batching rack 12 is located at the upper part of the screening frame 16. A third control valve 26 is fixedly installed at the position where the discharging pipe 25 is communicated with the feeding tank 23.

[0036] Specifically, when adding water, ice water is added into the storage tank 22. At this time, the second control valve 24 and the third control valve 26 are in the closed state. Then the second control valve 24 is opened. At this time, the ice water in the storage tank 22 enters the feeding tank 23. Then the second control valve 24 is closed, so that the inside of the feeding tank 23 is in a sealed state. Then the feeding tank 23 is evacuated to a vacuum state until the vacuum degree in the feeding tank 23 is the same as the vacuum degree between the vacuum cylinder 3 and the vacuum cover 4. Then the third control valve 26 is opened, so that the water in the feeding tank 23 enters the batching rack 12 and falls into the minced meat in the tray 5 through the screen 17. If seasonings were added before this water addition, then some of the seasonings remaining on the screen 17 can be washed away. If seasonings were not added before this water addition, then under the action of the hydrophobic coating of the screen 17, it will not be affected by the residual water when adding seasonings later.

[0037] As described above, such asFigure 2 , Figure 3 As shown in Figure 3 , it further includes a vacuum pumping assembly, which is installed inside the equipment frame 1 and is used to pump the inside of the vacuum cylinder 3 and the vacuum cover 4 after they are combined. The vacuum pumping assembly includes a vacuum pumping device 27 and a connecting pipeline 28. The vacuum pumping device 27 is installed inside the equipment frame 1. Between the output end of the vacuum pumping device 27 and the vacuum cylinder 3, and between the output end of the vacuum pumping device 27 and the feeding tank 23, there are connecting pipelines 28 communicating with each other.

[0038] Specifically, during vacuum pumping, the vacuum pumping device 27 is turned on. Through the setting of the connecting pipeline 28, the air in the inner cavity after the vacuum cylinder 3 and the vacuum cover 4 are combined, as well as the air in the feeding tank 23, is pumped. The pressure change is observed through the supporting pressure gauge to form a vacuum environment inside. When it is necessary to release the vacuum state, first turn off the vacuum pumping device 27, and then slowly open the exhaust valve at the corresponding position to allow the outside air to gradually enter the feeding tank 23 or the inner cavity after the vacuum cylinder 3 and the vacuum cover 4 are combined. Then, the pressure change in the tank is observed through the pressure gauge to ensure that the pressure gradually returns to the atmospheric pressure.

[0039] As mentioned above, as Figure 10 shown, it further includes a driving and rotating assembly, which is installed inside the equipment frame 1 and is used to control the rotation of the cutter shaft 8. The driving and rotating assembly includes a second driving and rotating motor 29, a rotating shaft 30, a first-level transmission member 31, and a second-level transmission member 32. The second driving and rotating motor 29 is fixedly installed inside the equipment frame 1. The rotating shaft 30 is rotatably installed inside the installation frame 6. The first-level transmission member 31 is installed between the second driving and rotating motor 29 and the rotating shaft 30. The second-level transmission member 32 is installed between the cutter shaft 8 and the rotating shaft 30. It further includes a support cylinder 33 and a third driving and rotating motor 34. The support cylinder 33 is fixedly installed inside the vacuum cylinder 3. The top of the support cylinder 33 is in rotational cooperation with the material tray 5. The third driving and rotating motor 34 is fixedly installed inside the bearing frame 2. The output end of the third driving and rotating motor 34 is fixedly connected to the material tray 5.

[0040] Specifically, when driving the material tray 5 to rotate, the third driving and rotating motor 34 is started, and the third driving and rotating motor 34 can drive the material tray 5 to rotate. Relative rotation occurs between the material tray 5 and the support cylinder 33 to improve stability. When driving the cutter shaft 8 to rotate, the second driving and rotating motor 29 is started. The power is transmitted to the rotating shaft 30 through the first-level transmission member 31, and then transmitted to the cutter shaft 8 through the second-level transmission member 32, so as to drive the blade 9 to rotate around the cutter shaft 8.

[0041] Among them, as Figure 10 shown, the first-level transmission member 31 preferably selects the form of belt drive to improve the overall stability, and the second-level transmission member 32 preferably selects the form of two meshing gears in combination.

[0042] The working principle or usage process of this application is as follows: When using a chopping machine to process meat, first wash and cut the meat to be processed and place it on the material tray 5. Then lower the knife cover 7 and start the third driving motor 34. The third driving motor 34 can drive the material tray 5 to rotate. Then start the second driving motor 29. The power is transmitted to the rotating shaft 30 through the transmission member 31 and then to the knife shaft 8 through the secondary transmission member 32, driving the blade 9 to rotate around the knife shaft 8 to chop the meat. In cooperation with the rotation of the material tray 5, the meat on the material tray 5 is chopped. To avoid the meat getting heated and affecting the meat quality, the chopping time is not too long. At this time, some salt is added. As the chopping progresses, when the meat paste becomes viscous but not fully emulsified, ingredients need to be added to the meat, such as adding water (preferably ice water) to play a role in cooling and improving the quality of the chopped meat paste. When adding liquid ingredients such as water, the water needs to be gradually added to the meat. As the chopping progresses, observe the state of the meat paste. When it becomes smooth on the surface and has no excess water, an appropriate amount of starch can be added to the meat paste. The addition amount of starch needs to be determined according to the quality of the meat.

[0043] After adding the starch, to optimize the emulsification structure, eliminate bubbles, enhance compactness, and improve the processing environment and efficiency, the meat paste also needs to be placed in a vacuum negative pressure environment. At this time, start the driving member 35. Under the action of the driving member 35, the vacuum cover 4 covers the vacuum cylinder 3, and a sealed space is formed between them. Then turn on the vacuum pumping device 27. Through the setting of the connecting pipeline 28, the air in the inner cavity formed by the cooperation of the vacuum cylinder 3 and the vacuum cover 4 is pumped out to form a vacuum environment inside. The degree of vacuum needs to be adjusted according to actual needs. At this time, the starch is evenly dispersed during the chopping process and combines with the protein in the meat paste to improve water retention. As the chopping progresses, when the meat paste gets heated and its viscosity increases significantly, the remaining water can be added.

[0044] When adding water, ice water is added into the interior of the storage tank 22. At this time, the second control valve 24 and the third control valve 26 are in the closed state. Then, the second control valve 24 is opened. At this time, the ice water in the storage tank 22 enters the feeding tank 23. Then, the second control valve 24 is closed, making the interior of the feeding tank 23 in a sealed state. Then, the feeding tank 23 is evacuated to a vacuum state until the vacuum degree in the feeding tank 23 is the same as the vacuum degree between the vacuum cylinder 3 and the vacuum cover 4. Then, the third control valve 26 is opened, so that the water in the feeding tank 23 enters the batching rack 12, passes through the screen 17 and falls into the minced meat in the tray 5. Under the action of the hydrophobic coating on the screen 17, the water will not remain on the screen 17. Then, the rotation speed is reduced for chopping and mixing, and the timed water addition is repeated until the minced meat shows a delicate luster and there are no visible particles to the naked eye, which means that the minced meat is completely emulsified. Then, seasonings (such as spices, sugar, monosodium glutamate, etc.) can be added to enhance the flavor, and the vacuum environment can reduce the volatilization of flavor substances.

[0045] Before evacuating to a vacuum, the required powdered seasonings are placed inside the corresponding feeding rack 13. After evacuating to a vacuum, when powdered materials (i.e., seasonings) need to be added, first open the corresponding first control valve 14, so that the seasonings fall onto the screen 17 on the screening frame 16. The pores of the screen 17 are relatively large, and a hydrophobic coating is provided on the surface of the screen 17. The seasonings falling onto the screen 17 will pass through the screen 17 and fall into the minced meat during the chopping and mixing process. At the same time, the first driving motor 19 is started, and the first driving motor 19 drives the cylindrical cam 20 to rotate. Through the setting of the slider 21, the frame of the screen 17 can be driven to move reciprocally, thus facilitating the batching to fall into the minced meat for chopping and mixing.

[0046] When the vacuum state needs to be released, first turn off the vacuum pumping device 27, and then slowly open the exhaust valve provided at the corresponding position to allow the outside air to gradually enter the interior of the feeding tank 23 or the inner cavity formed by the cooperation of the vacuum cylinder 3 and the vacuum cover 4. Then, observe the pressure change in the tank through the pressure gauge to ensure that the pressure gradually returns to the atmospheric pressure. After the chopping and mixing are completed, first stop the rotation of the tray 5, and then stop the rotation of the cutter shaft 8. And after use, it is necessary to clean the residues inside and outside the chopping machine in time and carry out appropriate maintenance to extend the service life of the equipment.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
