Description

Technical Field

[0001] This utility model relates to the field of meat product processing technology, and more specifically, to a liquid smoking device for fermented and air-dried meat products. Background Technology

[0002] Traditional smoking can cause harmful substances such as benzo[a]pyrene in the smoke to contaminate the surface of the meat. Therefore, it is necessary to use liquid smokers that do not contain harmful components such as benzo[a]pyrene to treat the meat. This ensures that the meat has the smoky flavor that consumers like, and also better guarantees product safety. There are two ways to apply liquid smokers: one is to evenly coat the surface of the meat that is about to be air-dried with the smoke liquid, and the other is to mix the smoke liquid into the marinade during the marinating stage of the meat so that the meat can absorb the smoky flavor of the smoke liquid into its interior during the marinating process.

[0003] Chinese Patent Publication No. CN212971499U discloses an automatic liquid smoking device for fermented and air-dried meat products, relating to the field of meat product manufacturing technology. The device includes a smoking chamber, with rotary motors bolted to both sides of the top of the chamber along a vertical axis. The output end of each rotary motor is connected to a rotating shaft, with a drive gear fixedly fitted to the end of the shaft furthest from the motor. This automatic liquid smoking device for fermented and air-dried meat products, through the drive gear, rotary motor, fixed hook, feeding nozzle, and smoker, enables rapid spraying of smoking liquid onto the meat products, further improving the smoking efficiency and avoiding uneven application of the smoking liquid. Furthermore, the device utilizes a turning motor, rotating block, and rotating plate to achieve rapid rotation and turning of the meat products, improving the smoking quality and preventing scorching in localized areas due to excessive smoking.

[0004] During the liquid smoking process of the aforementioned patented meat products, the fat in the meat gradually decomposes under high temperature, causing the meat to become lighter and softer. At the same time, moisture is lost through evaporation, which causes the volume of the meat products to shrink. Once the lower end of the meat products detaches from the rotating block during the shrinkage process, the meat products will inevitably swing around due to inertia and cannot maintain stability during rotation. Therefore, the smoking material is difficult to spray evenly on the surface of the meat products and will hit the inner wall of the container, making it impossible to guarantee the stability of the entire device. Utility Model Content

[0005] The present invention provides a liquid smoking device for fermented and air-dried meat products, which aims to solve the problem that the position of meat products cannot be adjusted according to changes in their volume during the liquid smoking process.

[0008] In a preferred embodiment, the lifting assembly includes a first motor mounted on the upper end of the smoking box, a lead screw mounted on the output end of the first motor, and a slide rod mounted inside the smoking box. The first motor is used to control the rotational movement of the lead screw, the drive block is threadedly connected to the lead screw, and the slide block is slidably connected to the slide rod.

[0009] In a preferred embodiment, the rotating assembly includes a second motor mounted on the upper end of the smoking box, a drive gear mounted on the output end of the second motor, a connecting shaft mounted inside the smoking box, a driven gear mounted on the lower end of the connecting shaft, and a drive chain mounted on the outside of the drive gear and the driven gear. The second motor is used to control the rotational movement of the drive gear.

[0010] In a preferred embodiment, the hoisting mechanism is used to hoist an object. The hoisting mechanism includes a meat hanging assembly and a smoking assembly. The meat hanging assembly is used to hoist meat products, and the smoking assembly is used to generate smoke to smoke the meat products.

[0011] In a preferred embodiment, the meat hanging assembly includes a plurality of chain hooks mounted on the outside of the drive chain and a meat product hook mounted on the lower end of the chain hooks.

[0012] In a preferred embodiment, the smoking assembly includes two smoking hooks installed inside the smoking chamber, two smokers disposed inside the smoking chamber, and a connecting hook installed on the upper end of the smokers, the connecting hook being connected to the smoking hooks.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention uses a liftable outer limiting ring and an inner limiting ring to dynamically adapt to the volume shrinkage of meat products during the smoking process, always maintaining radial constraint on the suspended meat products without fixing the lower end of the meat products. This prevents the meat products from detaching and effectively prevents them from swinging or impacting due to inertia during movement. This ensures both smoking efficiency and uniform flavor penetration, as well as the stability and safety of the equipment operation. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Refer to the instruction manual appendix Figures 1 to 5A liquid smoking device for fermented and air-dried meat products includes a smoking box 1, a sealing door 11 installed on the surface of the smoking box 1, a spray baffle frame 12 installed inside the smoking box 1, a drive block 13 installed inside the spray baffle frame 12, a limiting outer ring 14 installed on the surface of the drive block 13, a connecting plate 15 installed inside the limiting outer ring 14, a limiting inner ring 16 installed at the end of the connecting plate 15 away from the limiting outer ring 14, a sliding block 17 installed on the outer side of the limiting outer ring 14, a plurality of feeding nozzles 18 installed inside the smoking box 1, a power mechanism installed on the smoking box 1, and a hoisting mechanism installed on the smoking box 1.

[0024] It should be noted that the drive block 13, as the core component for power transmission of the lifting motion, drives the outer limiting ring 14 and the inner limiting ring 16, which are fixed to it by the connecting plate 15, to lift synchronously. The outer limiting ring 14 and the inner limiting ring 16 together form an adjustable height annular limiting space, which is used to constrain the position of the suspended meat products during the smoking process and prevent them from swinging significantly.

[0025] It is worth noting that the sliding block 17 cooperates with the sliding rod 213 to ensure that the outer limiting ring 14 and the inner limiting ring 16 remain stable during the lifting and lowering process and do not deflect. The spacing between the outer limiting ring 14 and the inner limiting ring 16 is reasonably designed to allow the meat products to sway slightly during rotation to achieve uniform contact with the smoking liquid, while also effectively limiting the radial movement of the meat products after their volume shrinks.

[0026] Refer to the instruction manual appendix Figures 1 to 4 The power mechanism is used to provide power for the rotation of meat products and the lifting of the drive block 13. The power mechanism includes a lifting assembly and a rotating assembly. The lifting assembly is used to control the lifting movement of the limiting outer ring 14 and the limiting inner ring 16, and the rotating assembly is used to control the rotation movement of the meat products.

[0027] It should be noted that the lifting assembly drives the lead screw 212 to rotate via the first motor 211. The drive block 13, which forms a threaded pair with the lead screw 212, then moves in a precise linear motion in the vertical direction under the guidance of the slide rod 213. The lifting of the drive block 13 directly drives the outer limit ring 14 and the inner limit ring 16 to rise and fall together.

[0028] Refer to the instruction manual appendix Figure 4 The lifting assembly includes a first motor 211 installed on the upper end of the smoking box 1, a lead screw 212 installed on the output end of the first motor 211, and a slide rod 213 installed inside the smoking box 1. The first motor 211 is used to control the rotational movement of the lead screw 212. The drive block 13 is threadedly connected to the lead screw 212, and the slide block 17 is slidably connected to the slide rod 213.

[0029] It should be noted that the cooperation between the slide rod 213 and the sliding block 17 is crucial. It not only provides guidance but also bears the lateral force that may be generated by the weight and rotation of the meat products, ensuring the smoothness of the lifting process and the structural rigidity. The operation of the first motor 211 is programmably controlled by an external controller. According to the preset smoking process, such as the estimated shrinkage of the meat products at different stages, the height of the limit ring is adjusted in a timely or real-time manner so that the limit ring is always in the optimal constraint position after the current volume shrinkage of the meat products.

[0030] Refer to the instruction manual appendix Figure 3 The rotating assembly includes a second motor 221 mounted on the upper end of the smoking box 1, a drive gear 222 mounted on the output end of the second motor 221, a connecting shaft 223 mounted inside the smoking box 1, a driven gear 224 mounted on the lower end of the connecting shaft 223, and a drive chain 225 mounted on the outside of the drive gear 222 and the driven gear 224. The second motor 221 is used to control the rotational movement of the drive gear 222.

[0031] It should be noted that the rotating component is driven by the second motor 221 to drive the drive gear 222 to rotate in both directions. The power is transmitted to the driven gear 224 through the drive chain 225, which drives the connecting shaft 223 to rotate, thereby realizing the reciprocating rotation of the drive chain 225.

[0032] Refer to the instruction manual appendix Figures 1 to 5 The hoisting mechanism is used to hoist objects. The hoisting mechanism includes a meat hanging component and a smoking component. The meat hanging component is used to hoist meat products, and the smoking component is used to generate smoke to smoke the meat products.

[0033] It should be noted that the hoisting mechanism integrates the meat hanging component that carries the meat products and the smoking component that provides the smoking smoke. The meat hanging component is directly suspended on the rotating drive chain 225 and rotates with the chain. The smoking component is fixed inside the smoking box 1 by suspension and its position is relatively fixed, but the smoke it generates covers the rotating meat products through the airflow inside the box.

[0034] It is worth noting that the smoking component is located in the middle of the inner limit ring 16, so that the meat products can rotate around the smoke emitted by the smoking component.

[0035] Refer to the instruction manual appendix Figure 3 The meat hanging assembly includes multiple chain hooks 311 mounted on the outside of the drive chain 225 and meat product hooks 312 mounted on the lower end of the chain hooks 311.

[0036] It should be noted that the chain hook 311 is detachably connected to the link of the drive chain 225, and the meat product hook 312 is suspended below the drive chain 225 through the chain hook 311 for directly hooking the meat products to be smoked.

[0037] Refer to the instruction manual appendix Figure 5 The smoking assembly includes two smoking hooks 321 installed inside the smoking chamber 1, two smoking devices 323 set inside the smoking chamber 1, and a connecting hook 322 installed on the upper end of the smoking device 323. The connecting hook 322 is connected to the smoking hooks 321.

[0038] It should be noted that the smoke hook 321 is fixedly installed at a suitable position on the top or side wall of the smoke chamber 1, and the smoke generator 323 is a device that generates liquid smoke, with a connecting hook 322 installed at its upper end. By hanging the connecting hook 322 onto the smoke hook 321, the smoke generator 323 can be conveniently suspended in a preset position inside the smoke chamber 1.

[0039] Refer to the instruction manual appendix Figure 2 The smoking chamber 1 is equipped with a smoke exhaust assembly, which is used to exhaust the smoke inside the smoking chamber 1. The smoke exhaust assembly includes a smoke exhaust pipe 411 installed on the surface of the smoking chamber 1, a smoke exhaust fan 412 installed inside the smoke exhaust pipe 411, and a pipe interface 413 installed on the surface of the smoke exhaust pipe 411.

[0040] It should be noted that the exhaust fan 412 is installed inside the exhaust pipe 411. After being powered on, it generates suction force to force the excess smoke, water vapor and volatile substances that may be generated after the smoking process in the smoke chamber 1 to be discharged outside the chamber. The pipe interface 413 is located outside the exhaust pipe 411 and is used to connect to the external exhaust pipe to guide the exhaust gas to the outside or the exhaust gas treatment system.

[0041] Working principle: Meat products are suspended from the chain hook 311 below the drive chain 225 by the meat product hook 312. After the sealing door 11 is closed, the device is started. The second motor 221 drives the drive gear 222 to rotate in both directions. This drives the driven gear 224 and the connecting shaft 223 to rotate through the drive chain 225, causing the drive chain 225 to rotate in both directions. This causes the suspended meat products to rotate uniformly in both directions within the smoking chamber 1. At the same time, the smoker 323 is connected to the smoking hook 321 through the docking hook 322, generating liquid smoking smoke. The meat products are evenly exposed to the smoke during rotation. The feeding nozzle 18 sprays liquid smoking agent onto the surface of the meat products through an external conveyor. During the smoking process, the meat products... Due to the shrinkage caused by dehydration, the volume decreases. At this time, the first motor 211 is operated by the programmable control of the external controller. The first motor 211 drives the lead screw 212 to rotate. The drive block 13, which is threaded to the lead screw 212, rises and falls vertically under the guidance of the slide rod 213, causing the outer limiting ring 14 and the inner limiting ring 16 to move down synchronously. The annular space formed by the outer limiting ring 14 and the inner limiting ring 16 dynamically adjusts its height as the meat product shrinks, always forming a radial constraint on the meat product to prevent it from falling off the hook or swinging and hitting the box wall due to the shrinkage of its volume. The sliding block 17 slides along the slide rod 213 to ensure the stable rise and fall of the limiting structure. After the smoking is completed, the exhaust fan 412 is started, and the exhaust gas is discharged from the smoking box 1 through the exhaust pipe 411 and the pipe interface 413.

[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
