Description

Technical Field

[0001] This utility model relates to the field of pork processing technology, specifically to a fully automatic atomized spray loss reduction device for rotating pre-cooling of pig carcasses. Background Technology

[0002] In the process of pig slaughtering and processing, the pre-cooling treatment of pig carcasses is an important step to reduce the loss of pig slaughter quality. At present, most slaughterhouses in China use traditional pre-cooling methods such as air cooling and cold water immersion. These pre-cooling methods have large losses and are difficult to achieve cleaning and preservation of pig carcasses. Therefore, spray pre-cooling has been widely used, mainly for cooling, cleaning and removing surface impurities.

[0003] Existing spraying technologies have several problems: traditional spraying equipment lacks a pre-spraying stage, and when the pig carcass surface is dry, the atomized spray droplets easily bounce back, resulting in uneven spraying and affecting the treatment effect; during the spraying process, the pig carcass posture is fixed, and the nozzle position is also fixed, creating spray dead zones, leading to poor effect, serious watermark problems, and affecting the appearance and market value of the carcasses; the spraying process requires manual operation and control, which is time-consuming, labor-intensive, and inefficient. Therefore, there is a need to develop a high-efficiency atomized spraying loss reduction technology and equipment required by livestock and poultry slaughtering enterprises. To address these problems, we propose an intermittent fully automatic atomized spraying loss reduction device for dynamic rotating pre-cooling of pig carcasses. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic atomized spraying loss reduction device for rotating pre-cooling of pig carcasses, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a conveying mechanism, a pre-spraying component, and a spraying component. The conveying mechanism extends forward from its starting end and is provided with a pre-spraying section (1). The pre-spraying component is installed below the pre-spraying section (1). The pre-spraying component includes a baffle plate (2) and multiple sets of pre-spraying heads (3) installed inside the baffle plate (2). The conveying mechanism includes multiple continuously bent conveying tracks (7). The spraying component is evenly arranged and installed following the conveying tracks (7) to achieve spraying. The spraying component includes multiple spray pipes (8) arranged in parallel, a mounting bracket (9), and a rotating component. Multiple sets of spraying heads (10) are evenly installed on the spray pipes (8). The spray pipes (8) all pass through the lifting holes of the mounting bracket (9) and rotate with it. The rotating component is used to drive the spray pipes (8) to rotate.

[0006] As a further embodiment of this utility model, the rotating assembly includes multiple sets of mounting plates (11), on which bearing seats (12) and drive motors are mounted. A double wheel axle (13) is installed inside the bearing seat (12), and a mating wheel (14) is fixedly installed on the outer wall of the spray pipe (8). The drive motor and the double wheel axle (13) are driven by a belt or chain, and the double wheel axle (13) and the mating wheel (14) are also driven by a belt or chain.

[0007] As a further embodiment of this utility model, the pre-spray assembly and the spray assembly respectively include a pre-spray pump (15) and a spray pump (16). The pre-spray pump (15) supplies water to all pre-spray heads (3) through a water supply pipe (6). The spray pump (16) is connected to all spray pipes (8) through a connecting pipe (17). The bottom of the connecting pipe (17) is connected to multiple sets of connecting sleeves (18). The spray pipes (8) pass through the connecting sleeves (18) and are connected to them and rotated.

[0008] As a further embodiment of this utility model, the pre-spray assembly further includes a sensor (4), a delay valve (5), and a water supply pipe (6). The sensor (4) and the delay valve (5) are installed on the water supply pipe (6). The sensor (4) is used to sense the pig carcass and cause the delay valve (5) to open with a delay. The water supply pipe (6) is used to supply water to all pre-spray heads (3).

[0009] As a further embodiment of this utility model, the conveying mechanism further includes a pulley hook and a carrying pole hook. The pulley hook is located within the conveying track, and the carrying pole hook is used to hook the pig carcass and connect with the pulley hook.

[0010] As a further embodiment of this utility model, the conveying mechanism further includes a deflection assembly, which includes a deflection baffle installed in the pre-spraying section and a protruding strip fixedly installed on the hook body of the pulley hook. When the protruding strip passes the deflection baffle, it causes the pulley hook to rotate.

[0011] As a further embodiment of this utility model, the deflection baffle includes a front baffle, a middle baffle, and symmetrical baffles on both sides. The front baffle and the middle baffle are distributed front to back and located on both sides. The symmetrical baffle on the side of the middle baffle is shorter than the symmetrical baffle on the side of the front baffle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. More uniform spraying and significant loss reduction: The spray pipe and spray head can swing synchronously, and with the arc-shaped rotating section of the conveyor track, the pig carcass can be sprayed evenly and comprehensively while it is dynamically rotating. This solves the industry bottleneck problem of dead spots and severe water marks caused by traditional fixed spray heads and static carcasses, reduces the dry loss of chilled meat and improves spraying efficiency.

[0014] 2. The integrated spray sensor and delay valve enable precise triggering of the carcass spray upon arrival. Pre-spray components are installed at the inlet of the atomization chamber for initial wetting. Food-grade lactic acid is used instead of water or traditional chemical antibacterial agents, which can safely and efficiently sterilize and clean the carcass while avoiding problems such as affecting the flavor and color of the meat. At the same time, the design of the baffle plate reduces the possibility of cross-contamination.

[0015] 3. The atomization is uniform and comprehensive, ensuring that the droplets form only a wet film on the carcass surface rather than flowing water, reducing the formation of watermarks on the carcass surface. Attached Figure Description

[0027] Please see Figure 1-9 The technical solution provided by this utility model is as follows: it includes a conveying mechanism, a pre-spraying component, and a spraying component. The starting end of the conveying mechanism extends forward to provide a pre-spraying section 1. The pre-spraying component is installed below the pre-spraying section 1. The pre-spraying component includes a baffle plate 2 and multiple sets of pre-spraying heads 3 installed inside the baffle plate 2. The conveying mechanism includes multiple continuously bent conveying tracks 7. The spraying component is evenly arranged and installed following the conveying tracks 7 to achieve spraying. The spraying component includes multiple spray pipes 8 arranged in parallel, a mounting bracket 9, and a rotating component. Multiple sets of spraying heads 10 are evenly installed on the spray pipes 8. The spray pipes 8 all pass through the lifting holes of the mounting bracket 9 and rotate with it. The rotating component is used to drive the spray pipes 8 to rotate.

[0028] When using this device, after the pig carcass is mounted, it first passes through the pre-spray section 1. 0.5% food-grade lactic acid is introduced into all the pre-spray nozzles 3, and then sprayed evenly onto the surface of the pig carcass to achieve preliminary wetting and sterilization, reducing the rebound of droplets during subsequent atomization spraying. At the same time, the water baffle 2 is vertically set on the left and right sides of the atomization chamber to prevent water from splashing into the external environment and to prevent cross-infection.

[0029] Meanwhile, the pre-spray nozzles 2 are evenly and equidistantly embedded in the baffle plate 2, and the installation height can cover the transportation of the pig carcass, effectively preventing water splashing while spraying the left and right sides of the pig carcass.

[0030] The pig carcass then continues to move along the conveyor track 7, where it is continuously sprayed by the spraying components. The components adaptively follow the rotation of the track at the arc turns, allowing the pig carcass to deflect and thus completely cover its surface. This ensures comprehensive and uniform spraying without blind spots during transport, preventing excessive water accumulation and watermarks. The pre-cooling effect is significant, improving spraying efficiency. After spraying, the carcass enters a cooling and acid removal process, which slows down ATP degradation, glycogen decomposition, lactic acid accumulation, and pH decrease, thus completing the atomization and loss reduction of the pig carcass and reducing the dryness loss of chilled meat.

[0031] The pre-spray pump 15 supplies spray liquid to all pre-spray heads 3 through the water supply pipe 6. The spray pump 16 supplies spray liquid to all spray heads through one of the spray pipes 8 and the connecting pipe 17. The spray liquid is food-grade lactic acid with a concentration of 0.5%.

[0032] After the pig carcass enters the pre-spraying section 1, the sensor 4 detects the pig carcass and sends a signal to the delay valve 5 after a delay of 2-5 seconds to ensure that the pig carcass can remain completely in the pre-spraying area for spraying. This causes the delay valve 5 to open, and then the water supply pipe 6 is opened to allow 0.5% food-grade lactic acid to be introduced into all the pre-spraying heads 3.

[0033] While the pig carcass is being transported and sprayed on the conveyor track 7, the drive motor is activated, which drives all the double-wheel shafts 13 and their corresponding mating wheels 14 to rotate via chain or belt drive. This, in turn, drives the corresponding spray pipes 8 to rotate, allowing the spray heads 10 to oscillate and spray at a certain angle. This ensures comprehensive and uniform spraying during the transport of the pig carcass, preventing water accumulation and watermarks from forming in a single location. The oscillation angle is preferably 45°, and intermittent left-right oscillation spraying provides the best effect.

[0034] The spray head 10 atomizes water using microporous technology to form a fine mist that covers the surface of the pig carcass. The atomized particle size is 50-100μm, the water pressure is 1.2MPa, and the flow rate is 3.0L / min, ensuring that the droplets form a wet film on the carcass surface rather than flowing water.

[0035] During this oscillating spraying process, the spray pipe 8 can rotate within the lifting hole of the mounting bracket 9 or within the connecting sleeve 18. Water is supplied simultaneously through the connecting pipe 17 and the connecting sleeve 18, allowing for spraying while rotating. The connection between the connecting sleeve 18 and the spray pipe 8 can be achieved through a rotary joint or other components capable of performing the aforementioned functions.

[0036] In the pre-spraying section 1, when the pig carcass reaches the deflection baffle, the protruding strip 21 of the pig carcass pulley hook 19 first contacts the front baffle 22. Blocked by the front baffle 22, the pulley hook 19 rotates, which in turn drives the carrying pole hook 20 to rotate, causing the pig carcass to deflect. After passing the front baffle 22, it reaches the middle baffle 23, where the protruding strip 21 contacts the middle baffle 23, causing the protruding strip 21 to rotate in the opposite direction. This causes the pulley hook 19 and the carrying pole hook 20 to rotate back to their original positions and then continue to deflect in the opposite direction, finally reaching the symmetrical baffle 24. The protruding symmetrical baffle 24 first... The protruding strip 21 is blocked back to its original position. As it continues to move, the two protruding strips 21 enter between the symmetrical baffles 24, thereby stabilizing the protruding strips 21 to their original state and restoring the pig carcass to its original state perpendicular to the baffle 3, while preventing it from shaking significantly. After it is basically stable, the pulley hook 19 continues to move through the symmetrical baffles 24 to realize the subsequent process. In the pre-spraying stage, the pig carcass can achieve a certain angle of deflection in both directions, thereby achieving a better coverage effect of pre-spraying on both sides of the pig carcass, which is beneficial to the subsequent spraying stage, thereby maximizing atomization loss reduction and reducing the dryness loss of chilled fresh meat.
