A deodorization apparatus for meat product processing

Abstract

This invention discloses a deodorizing treatment device for meat product processing, belonging to the field of meat processing technology. Its key technical features include a pretreatment tank and a main treatment tank. The pretreatment stirring mechanism quickly breaks the liquid film on the surface of the meat products, promoting the initial dissolution of blood, impurities, and some volatile odorous substances. Uniform pre-stirring also ensures thorough dispersion of the meat products, preventing clumping and stacking, thus avoiding incomplete deodorization and uneven stress caused by localized stacking. The pressure filter heat treatment mechanism enables continuous production with simultaneous feeding, pre-stirring, and deep deodorization. Furthermore, the hot water and reciprocating pressure filter in the main treatment tank operate synchronously, deeply deodorizing the meat products, complementing the initial deodorization from pre-stirring, further resolving residual odor and achieving excellent deodorization results.

Description

Technical Field

[0001] This invention relates to the field of meat processing, and more specifically to a deodorizing treatment device for processing meat products. Background Technology

[0002] In the meat processing industry, deodorization is a core pre-treatment step that ensures product quality, improves taste, and extends shelf life. It directly determines the flavor, safety, and market acceptance of subsequently processed products. The fishy smell of meat products mainly comes from its own metabolic products, blood residue, fat oxidation, and volatile odor substances such as ammonia, hydrogen sulfide, and indole produced by microbial activity. If the deodorization is not thorough, it will seriously affect the sensory experience of the product, reduce its added value, and even cause consumer rejection due to the odor, thus restricting the company's market competitiveness.

[0003] Chinese patent document CN215422656U discloses a processing device, a stirring mechanism, and a heating mechanism. The processing device includes a stirring mechanism installed inside, a heating mechanism welded to its upper surface, a motor connected to the upper surface of the outer casing, a rotating shaft mounted on the lower surface of the motor, and the motor driving the shaft to rotate. A drive gear is located at one end of the shaft, which in turn drives the drive gear to rotate. Several support pillars are welded to the lower surface of the outer casing to stabilize the processing device. A water inlet pipe is also welded to the upper surface of the outer casing, and a water outlet pipe is welded to the periphery of the outer casing. While this device can effectively remove the fishy smell from meat products, it has several drawbacks, as detailed below: First, the effect of removing fishy smell is limited and uneven. The stirring action of the stirring blade can only achieve surface contact between the meat raw material and the hot water. It is difficult to fully dissolve the fishy smell substances inside the meat raw material, especially the blood and metabolic products wrapped inside the muscle fibers, through simple stirring and hot water soaking. This results in incomplete removal of fishy smell, and some meat raw materials still have obvious fishy smell, which affects the uniformity of the product. Secondly, the efficiency of removing fishy smell is relatively low. In order to improve the effect of removing fishy smell as much as possible, it is often necessary to extend the stirring time or increase the hot water temperature. However, extending the stirring time will increase the mechanical damage to the meat raw materials, resulting in loose meat and loss of nutrients. Increasing the hot water temperature will easily cause the surface protein of the meat to denature, affecting the subsequent processing performance (such as marinating, shaping, etc.), and will also increase energy consumption. Secondly, during the process of removing the fishy smell, the dissolved fishy substances will remain in the hot water. As the stirring process continues, they will come into contact with the meat raw materials. This will not only fail to further improve the fishy smell removal effect, but may also cause the fishy substances to adhere to the surface of the meat again, causing secondary pollution and further reducing the quality of fishy smell removal. Finally, the existing equipment can only perform the single function of stirring and removing the fishy smell, and cannot simultaneously dehydrate the deodorized meat raw materials. An additional dehydration process is required, which increases the processing flow and equipment investment, reduces production efficiency, and increases the production cost of enterprises.

[0004] Therefore, there is a need for a deodorizing treatment device for meat product processing, which aims to solve the above problems. Summary of the Invention

A curved groove adapted to slide and connect to the traction column is provided on the curved push plate. The traction column is fixedly installed on the sleeve cylinder by the traction plate. The infusion cylinder is fixedly installed inside the main treatment box.

[0010] As a further embodiment of the present invention, the pressure filtration heat treatment mechanism further includes a liquid-drawing pipe and a liquid-delivering pipe for guiding liquid. Both the liquid-drawing pipe and the liquid-delivering pipe are connected to the interior of the liquid delivery cylinder. The other end of the liquid-delivering pipe is connected to the interior of the main treatment tank. A second one-way valve is provided on the liquid-delivering pipe. The other end of the liquid-drawing pipe is connected to the interior of the water storage tank. A first one-way valve is provided on the liquid-drawing pipe. A heating rod is provided inside the water storage tank. A water-adding pipe is provided on the water storage tank.

[0011] As a further embodiment of the present invention, the pretreatment stirring mechanism includes a first rotating shaft and a second rotating shaft for stirring control within the pretreatment tank. Both the first and second rotating shafts are rotatably mounted inside the pretreatment tank. Each of the first and second rotating shafts is provided with a plurality of stirring blades for stirring.

[0015] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art: This invention utilizes a pre-treatment stirring mechanism that can quickly break the liquid film on the surface of meat products, promoting the initial dissolution of blood, impurities, and some volatile odorous substances, thus reducing the deodorization pressure in the main processing tank. Furthermore, the uniform pre-stirring ensures that the meat products are fully dispersed, preventing clumping and stacking. This guarantees that each piece of meat product is evenly contacted by the filter plate and the injected hot water after being transported to the main processing tank, avoiding problems such as incomplete deodorization and uneven stress caused by localized stacking. Additionally, the conveying structure, designed to be compatible with the pre-stirring mechanism's outlet and the main processing tank's inlet, allows for direct and stable transport of the pre-stirred meat products without manual handling, effectively reducing manual operation steps and lowering the labor intensity of operators.

[0016] The specially designed pressure filter heat treatment mechanism enables continuous production of meat products by simultaneously pre-mixing and deeply deodorizing them. This allows for the rapid processing of large quantities of raw meat, significantly increasing the company's production capacity. The simultaneous operation of hot water and reciprocating pressure filtration in the main treatment tank allows for deep deodorization of meat products, complementing the initial deodorization achieved through pre-mixing. The reciprocating pressure filtration, through the reciprocating motion of the filter plates, generates uniform and continuous pressure on the meat products, forcing the blood, metabolic products, and other deep-seated odor-causing substances trapped inside the meat to be fully discharged. Simultaneously, the hot water injected can continuously penetrate into the meat muscle fibers under the reciprocating pressure, fully contacting the deep-seated, undissolved odor-causing substances, promoting their rapid dissolution, and being discharged with the liquid from the pressure filter, further resolving residual odor. Compared to simple mixing or high-pressure filtration, this method causes less damage to the meat quality, avoids denaturation of surface proteins, and thoroughly removes odor while maximizing the retention of moisture, protein, and other nutrients in the meat, making it easy for companies to promote and apply.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] See Figures 1-12 A deodorizing treatment device for meat product processing includes a main processing tank 1, on which a plurality of pre-processing tanks 2 for pre-processing meat products are connected and installed, and further includes: A pre-treatment stirring mechanism, installed on the pre-treatment chamber 2 and controlled and driven by the pressure filter heat treatment mechanism, is used to pre-stir the meat products placed inside; and The feeding transmission mechanism is installed at the connection between the pretreatment box 2 and the main treatment box 1. It is used to transport the pre-mixed meat products in the pretreatment box 2 to the main treatment box 1 for processing. The feeding transmission mechanism includes a sealing plate 21 for feeding control. The pretreatment box 2 is provided with a first feeding hole 25 for feeding, and the first feeding hole 25 is adapted to seal and connect with the sealing plate 21. A feeding pipe 26 for guiding the material into the push box 27 is provided on one side of the sealing plate 21.

[0034] Furthermore, the pretreatment stirring mechanism includes a first rotating shaft 6 and a second rotating shaft 19 for stirring control within the pretreatment tank 2. Both the first rotating shaft 6 and the second rotating shaft 19 are rotatably mounted inside the pretreatment tank 2. Each of the first rotating shaft 6 and the second rotating shaft 19 is provided with a plurality of stirring blades 20 for stirring. The first rotating shaft 6 is rotatably connected to a first connecting column 9 via a first bevel gear pair 7, and the second rotating shaft 19 is rotatably connected to a second connecting column 17 via a second bevel gear pair 18. The pretreatment tank 2 is also provided with a first drain pipe 4 for draining liquid, and a filter screen 5 for filtration is provided inside the first drain pipe 4. The top of the pretreatment tank 2 is provided with a tank cover 3.

[0035] Furthermore, the feeding transmission mechanism also includes a second motor 24 for driving the sealing plate 21 to perform limited docking. The sealing plate 21 is limited to slide by the guide plate 22. A rotating gear 23 is meshed on the sealing plate 21. The rotating gear 23 is fixedly connected to the output shaft of the second motor 24, and the second motor 24 is fixedly installed on the main processing box 1.

[0036] Furthermore, the feeding transmission mechanism also includes a pusher plate 30 for guiding and advancing materials. The pusher plate 30 is fixedly connected to the output end of the electric push rod 31. The electric push rod 31 is fixedly installed on the outside of the pusher box 27. The pusher box 27 is provided with a second guide hole 28 adapted to connect with the guide pipe 26. The pusher box 27 and the guide pipe 26 are both fixedly installed on the outside of the main processing box 1. The pusher box 27 is provided with a guide slope 29 for guiding, and the pusher box 27 is connected to the interior of the main processing box 1.

[0037] Preferably, when processing meat products, the lid 3 can be opened and the corresponding meat products and a small amount of deodorizing agent can be put into the pretreatment box 2. At this time, under the joint drive of the pressure filter heat treatment mechanism, the pre-stirring treatment of the meat products in the pretreatment box 2 can be well achieved, thereby facilitating the subsequent further deodorizing treatment. The specific operation method is as follows: The output shaft of the first motor 8 drives the first rotating shaft 6 to rotate, and under the transmission action of the first bevel gear pair 7, it drives the first connecting column 9 to rotate. Since the first rotating ball 11 rotates inside the first docking plate 10 and the second rotating ball 15 rotates inside the second docking plate 16, and the first sliding rod 12 slides on the first rotating ball 11 and the second sliding rod 14 slides on the second rotating ball 15, the second connecting column 17 is driven to follow the first connecting column 9 to perform corresponding rotation operations. Thus, under the transmission connection of the second bevel gear pair 18, the second connecting column 17 can drive the second rotating shaft 19 to rotate. At this time, the stirring blades 20 on the first rotating shaft 6 and the second rotating shaft 19 can pre-stir the meat products in the pretreatment box 2. The blood and other impurities stirred out can be discharged from the first drain pipe 4 on the pretreatment box 2. The filter screen 5 set on the first drain pipe 4 can filter and block the meat products accordingly.

[0038] After the pre-mixing process is completed, when the meat products in the pre-processing box 2 are transported to the next processing station, the specific operation is as follows: With the continued mixing action of the stirring blades 20 on the first rotating shaft 6 and the second rotating shaft 19, the output shaft of the second motor 24 drives the rotating gear 23 to rotate. The rotating gear 23, in its meshing connection with the sealing plate 21, drives the two sealing plates 21 closer together, completing the opening of the first guide hole 25 on the pre-processing box 2. This allows the meat products at the first guide hole 25 to pass through the guide pipe 26 and fall into the pusher box 27. (See details...) Figure 5 and Figure 11 As shown, when the meat products in the pretreatment box 2 are completely inside the pusher box 27, the first motor 8 stops operating, so that the filter plate 50 in the main treatment box 1 is at its highest position, and the electric push rod 31 pushes the meat products in the pusher box 27 into the main treatment box 1, thus facilitating the subsequent deodorization processing.

[0039] It should be noted that all meat products undergoing pre-processing are of the type that can pass through the first feed hole 25 and the feed tube 26.

[0040] This pre-mixing process quickly breaks down the liquid film on the surface of meat products, promoting the initial dissolution of blood, impurities, and some volatile odorous substances, thus reducing the deodorization pressure on the main processing tank. Furthermore, uniform pre-mixing ensures that the meat products are fully dispersed, preventing clumping and stacking. This guarantees that each piece of meat will be evenly contacted by the filter plate and the injected hot water after being transported to the main processing tank, avoiding incomplete deodorization and uneven pressure caused by localized stacking. This improves the uniformity of the overall deodorization effect from the source.

[0041] In addition, the conveying structure, by adopting a design that adapts to the discharge port of the pre-mixing mechanism and the inlet of the main processing box, can achieve direct and stable conveying of pre-mixed meat products without manual transfer. This effectively reduces manual operation steps, lowers the labor intensity of operators, and avoids meat damage and raw material loss caused by meat products falling or colliding during manual transfer, thus saving processing costs. Furthermore, the conveying structure adopts a sealed design, which can effectively prevent meat products from being contaminated by the external environment during the conveying process, and prevent the fishy substances dissolved during the pre-mixing process from spreading into the production workshop, improving the production environment and further enhancing the operational stability and reliability of the equipment.

[0042] like Figures 1-10 As shown, this embodiment, based on the above embodiment, also includes a pressure filtration and heat treatment mechanism, which is installed in the main processing box 1 and is used to perform pressure filtration and heat treatment on the incoming meat products. The pressure filtration and heat treatment mechanism includes a pressure plate 50 for pressure filtration, a heat supply cylinder 32, and a water storage tank 42. The pressure plate 50 is slidably connected to the fixed shaft 49 through the sleeve 13. The fixed shaft 49 is fixedly installed inside the main processing box 1 through the fixed plate 46, and the water supply cylinder 32 supplies water through the movement of the pressure plate 50.

[0043] Furthermore, the filter press heat treatment mechanism also includes a first connecting column 9 for driving the filter press plate 50 to reciprocate up and down for filter pressing. The first connecting column 9 is rotatably connected to a first rotating shaft 6 via a first bevel gear pair 7. The first rotating shaft 6 is fixedly connected to the output shaft of the first motor 8. One end of the first connecting column 9 is fixedly connected to a first docking plate 10. A first rotating ball 11 is adapted to be rotatably connected to the first docking plate 10. A first sliding rod 12 is slidably connected to the first rotating ball 11. One end of the first sliding rod 12 is fixedly installed on the sleeve 13, and the first connecting column 9 and the first sliding rod 12 are arranged parallel to each other.

[0044] Furthermore, the filter press heat treatment mechanism also includes a second connecting column 17 and a second sliding rod 14 for driving the filter press plate 50 on the sleeve cylinder 13 to move synchronously and assistedly. The sleeve cylinder 13 is also fixedly connected to the second sliding rod 14, and the second sliding rod 14 is arranged perpendicularly to the first sliding rod 12. The second sliding rod 14 is slidably connected to the second rotating ball 15, and the second rotating ball 15 is rotatably connected to the second docking plate 16. The second docking plate 16 is fixedly connected to the second connecting column 17, and the second connecting column 17 is arranged parallel to the second sliding rod 14.

[0045] Furthermore, the pressure filtration heat treatment mechanism also includes a piston plate 33 for driving the infusion cylinder 32 to perform infusion operation. The piston plate 33 is slidably connected to the inside of the infusion cylinder 32 by a piston rod 34. One end of the piston rod 34 is fixedly connected to a curved push plate 35. A spring 36 is provided at the connection between the curved push plate 35 and the infusion cylinder 32. A curved groove 37 is provided on the curved push plate 35 to adapt to the sliding connection of the traction column 39. The traction column 39 is fixedly installed on the sleeve cylinder 13 by a traction plate 38. The infusion cylinder 32 is fixedly installed inside the main treatment box 1.

[0046] Furthermore, the pressure filtration heat treatment mechanism also includes a liquid suction pipe 40 and a liquid delivery pipe 44 for guiding liquid. Both the liquid suction pipe 40 and the liquid delivery pipe 44 are connected to the inside of the liquid delivery cylinder 32. The other end of the liquid delivery pipe 44 is connected to the inside of the main treatment tank 1. A second one-way valve 45 is provided on the liquid delivery pipe 44. The other end of the liquid suction pipe 40 is connected to the inside of the water storage tank 42. A first one-way valve 41 is provided on the liquid suction pipe 40. A heating rod is provided inside the water storage tank 42. A water filling pipe 43 is provided on the water storage tank 42.

[0047] Furthermore, a second drain pipe 48 is fixedly connected to the bottom of the main processing box 1, and a filter screen 5 for filtration is provided on the second drain pipe 48. A material handling door 47 is installed on the outside of the main processing box 1.

[0048] Preferably, in this embodiment, when processing the meat products in the main processing box 1, the first motor 8 is driven again, the sealing plate 21 pre-seals the first guide hole 25 at the pre-processing box 2, and pre-stirring can be performed in the pre-processing box 2 accordingly. The second connecting column 17 rotates in accordance with the first connecting column 9. At this time, under the connection relationship between the first docking plate 10 and the second docking plate 16, the sleeve cylinder 13 can drive the filter press plate 50 to reciprocate downward pressing, thereby facilitating the filter pressing of the meat products below. Simultaneously, the sleeve cylinder 13 drives the traction plate 38 to reciprocate up and down, thereby adapting to the curved push plate 35. Under the action of docking and the elastic reset of spring 36, the piston plate 33 can be driven to move back and forth inside the infusion cylinder 32. Thus, under the one-way action of the first one-way valve 41 set on the liquid suction pipe 40 and the second one-way valve 45 set on the liquid delivery pipe 44, the water in the water storage tank 42 can be drawn and injected into the main processing tank 1. Since the water storage tank 42 is equipped with a heating rod, the heated water can be injected into the main processing tank 1. At this time, the pressure filtration operation of meat products can be better realized. The sewage can be discharged from the second drain pipe 48 on the main processing tank 1, and the processed meat products can be taken out from the material receiving door 47, thus completing the deodorization treatment of the meat products.

[0049] This equipment, through its processing method, can effectively achieve continuous production of "simultaneous feeding and pre-mixing while deeply deodorizing," thereby enabling the rapid processing of large quantities of meat raw materials, significantly improving the company's production capacity, further reducing the labor intensity of operators, and realizing the automated and continuous operation of meat deodorization processing. Furthermore, the simultaneous operation of hot water and reciprocating filter press in the main processing tank can deeply deodorize meat products, complementing the initial deodorization process of pre-mixing. The reciprocating filter press, through the reciprocating motion of the filter plates, generates uniform and continuous pressure on the meat products, forcing the blood, metabolic products, and other deep-seated odorous substances trapped inside the meat to be fully discharged. Simultaneously, the hot water injected can continuously penetrate into the meat muscle fibers under the reciprocating pressure, fully contacting the deep-seated undissolved odorous substances, promoting their rapid dissolution, and being discharged with the liquid from the filter press, further resolving residual odor.

[0050] On the other hand, pre-mixing only needs to complete the initial dispersion and surface deodorization, without extending the mixing time. It can effectively retain the muscle fiber structure of the meat. At the same time, the reciprocating pressure filtration of the main processing box is a gentle extrusion, which causes less damage to the meat quality compared to single mixing or high-pressure filtration. It avoids denaturation of protein on the surface of the meat, which can thoroughly remove the fishy smell and retain the maximum amount of moisture, protein and other nutrients in the meat, making it easy for enterprises to promote and apply.

[0051] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0052] 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 within the protection scope of the present invention.
