Description

Technical Field

[0001] This utility model relates to the field of cured meat fermentation technology, and in particular to a cured meat fermentation device with an automatic turning function. Background Technology

[0002] Cured meat is a traditional meat product made by curing, fermenting, and air-drying fresh meat. Fermentation is its core process. On the one hand, it serves to prevent spoilage and preserve quality, reducing water activity and producing organic acids to inhibit spoilage bacteria through the action of microorganisms and enzymes. On the other hand, it creates a unique flavor, as proteins and fats decompose under the catalysis of microorganisms and endogenous enzymes, transforming into flavor substances such as amino acids and esters. The Maillard reaction then gives cured meat its unique color, aroma, and rich taste. To ensure the uniformity and stability of the fermentation quality, the meat needs to be turned over during the fermentation process.

[0003] As shown in the reference case "A Fermentation and Drying Chamber for Cured Meat" (Announcement No. CN221011760U), by setting a rotating ring and a hook, the hook can rotate with the rotation of the rotating ring. The air inlet pipe is set in the middle of the rotating ring, and the air outlet set in the air inlet pipe can output air into the interior of the chamber from all directions, and can carry out a thorough drying process for all the cured meat placed therein.

[0004] The aforementioned application achieves multi-angle circulating air drying of the cured meat by placing hooks below a rotatable rotating ring and using a drive component to drive the rotating ring, causing all hooks and the suspended cured meat to revolve around the central air inlet and outlet. However, since the connection between the hooks and the fixed rod above is only a simple rotational connection, the rotation of the cured meat itself is not actively controlled, but rather passively achieved by the torque generated by the airflow pushing the irregular surface of the cured meat during the air drying process. When the suspended cured meat is relatively regular in shape, has a uniform mass distribution, or is in a specific hanging posture, the wind force may not be sufficient to drive it to generate an effective and continuous rotation. This will cause the cured meat to always face the main airflow on the same side or in a fixed area during the long-term revolution, while the leeward side and the side depressions cannot obtain sufficient and uniform air drying and airflow exchange. This easily leads to uneven drying rates in different parts of the cured meat, ultimately affecting the uniformity of the product's color and flavor. Utility Model Content

[0005] Therefore, it is necessary to provide a bacon fermentation device with an automatic turning function to address the problem in the above-mentioned application that it is impossible to evenly air-dry different parts of the bacon.

[0006] A bacon fermentation device with automatic turning function includes: a box and an air intake fan installed at the top of the box, and two sets of exhaust fans are provided on both sides of the box; an air outlet is provided inside the box.

[0007] The air drying mechanism includes a fixed plate fixedly connected to the inner wall of the box, and a plurality of hooks are provided below the fixed plate, which are evenly arranged in a circle around the outer periphery of the air outlet.

[0008] In one embodiment, the inner wall of the fixed plate is rotatably connected to a drive ring, and the interior of the fixed plate is provided with a positioning ring fixedly connected to the top wall of the box, with the air outlet penetrating through the positioning ring.

[0009] In one embodiment, a first rack is provided on the outer side of the drive ring, and a second rack is provided on the inner side of the drive ring.

[0010] In one embodiment, a first gear is rotatably connected to the inner wall of the fixed plate, and a servo motor is fixedly connected to the inner top wall of the housing. The first gear is fixedly connected to the drive end of the servo motor, and the first gear meshes with a first rack.

[0011] In one embodiment, a third rack is provided on the outer side of the positioning ring, and a plurality of hooks are provided between the second rack and the third rack.

[0012] In one embodiment, a second gear is provided between the second rack and the third rack, the second gear meshing with the second rack and the third rack, and the top end of the hook is fixedly connected to the second gear.

[0013] In one embodiment, a support ring is fixedly connected to the inner top wall of the housing, the support ring is disposed above the fixed plate, and the top end of the second gear is disposed inside the support ring via a connecting rod.

[0014] In one embodiment, the inside of the box is provided with a collection frame, which is a pull-out type.

[0015] Beneficial effects

[0016] 1. By placing the hook below the second gear and positioning the second gear between the second and third racks, the second gear can be actively and forcibly driven to rotate at a uniform speed while revolving stably around the air inlet pipe between the second and third racks. This ensures that all surfaces of the cured meat, regardless of its shape and weight distribution, are periodically and evenly exposed to the main airflow, thus achieving all-round airflow exchange. This significantly improves the drying rate of the cured meat and the uniformity of the fermentation environment, effectively avoiding quality deterioration caused by insufficient local air drying, and ensuring the uniformity and stability of the color, flavor, and texture of the finished cured meat.

[0017] 2. By setting a pull-out collection frame inside the box, the oil and moisture dripping during the air-drying process of cured meat can be collected, which effectively reduces the scope of contamination of the box by dripping substances and the growth of bacteria during the air-drying process. It can not only collect valuable cured meat oil for subsequent use, but also facilitate regular cleaning, significantly reducing cleaning and maintenance costs, thereby ensuring the stable air-drying quality and food safety of cured meat products.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The following is combined with Figures 1-5 This invention describes a bacon fermentation device with an automatic turning function.

[0028] In one embodiment, a bacon fermentation device with automatic turning function includes: a box 100 and an air intake fan 200 disposed at the top of the box 100; two sets of exhaust fans 210 are provided on both sides of the box 100; and an air outlet duct 300 is provided inside the box 100.

[0029] The air drying mechanism 400 includes a fixing plate 410 fixedly connected to the inner wall of the housing 100. Multiple hooks 420 are provided below the fixing plate 410, and the hooks 420 are evenly arranged in a circle around the air outlet 300.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a drive ring 411 is rotatably connected to the inner wall of the fixing plate 410. A positioning ring 412 is fixedly connected to the inner top wall of the housing 100 inside the fixing plate 410, and the air outlet duct 300 passes through the positioning ring 412. A first rack 4111 is provided on the outer side of the drive ring 411, and a second rack 4112 is provided on the inner side of the drive ring 411. A first gear 414 is rotatably connected to the inner wall of the fixing plate 410, and a servo motor is fixedly connected to the inner top wall of the housing 100. The first gear 414 is fixedly connected to the drive end of the servo motor, and the first gear 414 meshes with the first rack 4111. A third rack 4121 is provided on the outer side of the positioning ring 412, and multiple hooks 420 are disposed between the second rack 4112 and the third rack 4121. A second gear 421 is provided between the second rack 4112 and the third rack 4121. The second gear 421 meshes with the second rack 4112 and the third rack 4121. The top end of the hook 420 is fixedly connected to the second gear 421. A support ring 413 is fixedly connected to the inner top wall of the housing 100. The support ring 413 is located above the fixed plate 410. The top end of the second gear 421 is located inside the support ring 413 via a connecting rod.

[0031] In this embodiment, the top ends of the intake fan 200 and the exhaust duct 300 are interconnected. The bottom end of the exhaust duct 300 is closed, and its interior is hollow. At the same time, multiple ventilation holes are opened on the surface of the exhaust duct 300. After the intake fan 200 is started, its internal fan blades rotate to transport outside air into the exhaust duct 300. After the airflow enters the exhaust duct 300, it rushes out through the ventilation holes and air-dries the cured meat near the exhaust duct 300. Meanwhile, multiple hooks 420 are arranged in an alternating pattern. The top end of the second gear 421 is provided with a connecting rod. The top end of the connecting rod is spherical, and the support ring 413 has a groove inside that mates with the top end of the connecting rod. The top end of the connecting rod slides in the groove. The spherical shape of the connecting rod and the support ring 413 provide the main support for the second gear 421, while the second rack 4112 and the third rack 4121 mainly provide power for the second gear 421.

[0032] like Figure 1 and Figure 2 As shown, a collection box 430 is provided inside the box 100, and the collection box 430 is a pull-out type.

[0033] In this embodiment, since the cured meat will drip oil and moisture during the air-drying process, the collection frame 430 is set at the bottom of the box 100 and covered with multiple hooks 420, so that the oil dripping from the cured meat can be collected by the collection frame 430. The staff only needs to periodically pull the collection frame 430 out of the box 100 to clean the impurities inside.

[0034] Working principle: First, the staff evenly hangs the cured meat to be processed on multiple hooks 420 inside the box 100. Then, the box door is closed and the entire device is started. After the device is started, the air circulation system begins to work: the intake fan 200 operates, drawing in outside air and delivering it to the exhaust duct 300 inside the box 100. The airflow then blows out from multiple ventilation holes evenly distributed on the surface of the exhaust duct 300, continuously and evenly drying the cured meat surrounding it. At the same time, the exhaust fan 210 works synchronously, continuously expelling the humid air inside the box 100, thereby forming a stable and efficient airflow circulation inside the box, ensuring that moisture and volatile substances can be removed in time.

[0035] Simultaneously with the start of the air-drying system, the servo motor starts, and its output shaft drives the first gear 414 to rotate. The first gear 414 meshes with the first rack 4111, thereby driving the entire drive ring 411 to move along the inner wall of the fixed plate 410. The rotation of the drive ring 411 drives multiple second gears 421 to move. The second gear 421 meshes with the second rack 4112 and the third rack 4121 at the same time, so that while the second gear 421 revolves with the drive ring 411, it can also generate a uniform rotation around its own axis under the combined action of the two racks. Finally, this motion is transmitted to the suspended cured meat through the hook 420, so that each piece of cured meat simultaneously revolves around the air outlet 300 and rotates around the axis of the hook 420, ensuring that every surface of the cured meat can be periodically and evenly exposed to the optimal airflow path, achieving true all-round air-drying without dead angles, and greatly improving the air-drying efficiency and product quality uniformity.

[0036] It should be noted that the intake fan 200, exhaust fan 210, air outlet 300, and hook 420 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the intake fan 200 and exhaust fan 210 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
