Description

Technical Field

[0001] The invention relates to the field of slaughtering, in particular to a steaming and dehairing device used in a pig slaughtering and processing line. Background Art

[0002] Scalding and hair removal: (1) Scalding in a pig scalding pool: unload the bled pigs into the receiving platform of the pig scalding pool through the pig unloader, and slowly slide the pigs into the pig scalding pool for scalding. The scalding methods include manual scalding and pig scalding by shaking. The water temperature of the scalding pool is generally controlled between 58-62℃. If the water temperature is too high, the pigs will be scalded white, which will affect the hair removal effect. Scalding time: 4-6 minutes. A "skylight" is designed just above the pig scalding pool to discharge water vapor. (2) Scalding in a closed canal pig scalding pool: the bled pigs are automatically transported from the pig bleeding automatic conveyor line through the downhill curved track into the canal pig scalding pool, and scalded in the closed pig scalding pool for 4-6 minutes. During the transportation and scalding process, a pressure rod should be designed to press the pigs to prevent them from floating up. The scalded pigs are automatically transported out by the pig automatic conveyor line through the uphill curved track. This type of pig scalding pool has a good insulation effect. (3) Tunnel steam scalding system: The bled pigs are hung on the automatic pig bleeding conveyor line and put into the tunnel for scalding. This scalding method greatly reduces the labor intensity of workers, improves work efficiency, realizes the mechanized operation of pig scalding, and avoids the disadvantages of cross infection between pigs, making the meat more hygienic. This scalding method is currently the most advanced and ideal scalding method. (4) Horizontal dehairing: This dehairing method mainly uses 100-type dehairing machines, 200-type mechanical (hydraulic) dehairing machines, and 300-type mechanical (hydraulic) dehairing machines. The scalded pigs are taken out of the scalding pool with a rake and automatically put into the dehairing machine. The pig hair is shaved clean by the rolling of the large drum and the scraping of the soft dehairing claws. Then the dehaired pigs are put out and put into the scraping conveyor or the clean water pool for scraping. (5) Spiral automatic dehairing: This type of dehairing is used in conjunction with canal scalding and tunnel steam scalding. The scalded pigs are unloaded from the automatic bleeding conveyor line through the pig unloader and enter the dehairing machine. The dehaired pig bodies are pushed out from the other end of the dehairing machine through the scraping of soft scraping claws and spiral propulsion, and then enter the scraping conveyor for scraping.

[0003] The existing scalding pool and closed canal scalding pool require the pigs to be unloaded from the guide rails and placed in the scalding pool for dehairing, and then manually hung on the guide rails again. The process is complicated and easily interrupted, and is not suitable for assembly line slaughter. The steam scalding system in the tunnel is separate from the dehairing equipment, and the two each occupy a certain space, resulting in a large footprint, and the dehairing equipment needs to be cleaned separately. Summary of the invention

[0004] In order to meet the above-mentioned demand for integrating the steam scalding system into the dehairing equipment and cleaning the dehairing equipment simultaneously, the present invention proposes a steam scalding and dehairing equipment for use in a pig slaughtering and processing line.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0007] The cleaning drum includes a hollow tube, which is connected to a steam supply device through a ring-shaped collecting pipe rotatably connected at the lower end. The collecting pipe connects multiple hollow tubes. An output shaft of a motor is fixedly connected above the hollow tube, and the motor is fixed on the upper surface of the shell.

[0008] The spin nozzles and the scrapers are both provided in multiple groups, each group is provided with multiple and annularly distributed on the outer wall of the hollow tube, and the groups of the spin nozzles and the scrapers are arranged at intervals along the axial direction of the hollow tube.

[0009] The spin nozzle is rotatably connected to the hollow tube, and the connection is set as an inlet. The interior of the spin nozzle is provided with conical spiral blades, which divide the interior of the spin nozzle into multiple areas, and each area corresponds to an outlet.

[0010] The scraper is made of a flexible material, and its cross section has a certain curvature.

[0011] The lower surface of the shell is provided with a sewage outlet, and the upper surface is provided with a moving slot for the hook in the guide rail to move. The shell is respectively provided with a guide plate and a lead-out plate at the front and rear of the processing sequence.

[0012] The guide rail is installed on the upper part of the shell through a fixing frame. A moving groove is opened on the side of the guide rail. A moving seat is arranged in the moving groove. The hook is hung below the moving seat.

[0013] The beneficial effects of the present invention are:

[0014] The present invention provides a cleaning drum with multiple scrapers at staggered positions inside a shell, and a plurality of self-spinning nozzles are provided on the outer wall of a built-in hollow tube of the cleaning drum. Steam is sprayed by the self-spinning nozzles to fumigate and heat the pig carcasses, and the scrapers are used to shave the heated pig carcasses.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention but not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present invention.

[0026] like Figures 1 to 7 As shown, a steaming and dehairing device for use in a pig slaughtering and processing line includes a guide rail 2 for suspending and guiding the movement of a pig carcass, the guide rail 2 is mounted on a shell 1, a plurality of cleaning drums 3 for simultaneously steam heating the pig carcass and rotating to dehair the pig carcass are arranged inside the shell 1, self-spinning nozzles 32 for spraying steam and self-cleaning and a scraper 33 for dehairing the pig are arranged at intervals on the surface of the cleaning drum 3, and the self-spinning nozzles 32 and the scraper 33 of the plurality of cleaning drums 3 are staggered with each other.

[0027] The cleaning drum 3 includes a hollow tube 31, which is connected to a steam supply device through a circular collecting pipe 35 that is rotatably connected at the lower end. The collecting pipe 35 connects multiple hollow tubes 31. The output shaft of a motor 34 is fixedly connected to the upper part of the hollow tube 31, and the motor 34 is fixed to the upper surface of the shell 1. The collecting pipe 35 is provided with two inlet ports 351, the inlet port 351A is used to connect to the steam supply device for steam supply, and the inlet port 351B is used to connect to the water supply device for warm water supply. The reason why it is set to warm water is to avoid the two opposite cold and hot states of cold water and steam from causing damage to the hollow tube 31 and the collecting pipe 35. On the contrary, the flushing of high-temperature water makes the hollow tube 31 and the collecting pipe 35 always maintain a high-temperature state, which is not conducive to the use of the hollow tube 31 and the collecting pipe 35, and also causes waste of high-temperature water. The warm water formed by mixing high-temperature water and cold water can cool and dissipate the hollow tube 31 and the collecting pipe 35 to a certain extent, thereby alleviating their high-temperature state.

[0028] There are multiple groups of self-spinning nozzles 32 and scrapers 33, each group is provided with multiple nozzles and annularly distributed on the outer wall of the hollow tube 31, and the groups of self-spinning nozzles 32 and scrapers 33 are arranged at intervals along the axial direction of the hollow tube 31. The self-spinning nozzles 32 and scrapers 33 are arranged at intervals, when the self-spinning nozzles 32 of one hollow tube 31 perform steam spraying, the scraper 33 of another hollow tube 31 performs hair planing cleaning, and the cleaning is staggered to avoid interference with each other, making the operation smoother.

[0029] The self-spinning nozzle 32 is rotatably connected to the hollow tube 31, and the connection is set as an inlet 322. The interior of the self-spinning nozzle 32 is provided with a conical spiral blade 321, and the blade 321 divides the interior of the self-spinning nozzle 32 into a plurality of areas, each area corresponding to an outlet 323. Steam and warm water are filled into the self-spinning nozzle 32 under pressure. As the diameter of the front end of the self-spinning nozzle 32 gradually decreases, the pressure increases and drives the impeller in the self-spinning nozzle 32 to rotate. The rotation of the impeller drives the self-spinning nozzle 32 to rotate along the mouth of the hollow tube 31, so as to realize the scattering of the self-spinning nozzle 32 and expand the area of ​​fumigation and flushing.

[0030] The scraper 33 is made of a flexible material, and the cross section is provided with a certain curvature. The scraper 33 is provided with a flexible material to avoid causing damage to the scalded pig carcass, resulting in a bad taste of pork and inconvenience in subsequent skinning. The scraper 33 is provided with a certain curvature to facilitate the dehairing of the pig carcass when rotating.

[0031] The lower surface of the housing 1 is provided with a drain port 12, and the upper surface is provided with a moving slot 11 for the hook 24 in the guide rail 2 to move. The housing 1 is provided with a guide plate 13 and an outlet plate 14 at the front and rear of the processing sequence. The drain port 12 is provided with a funnel shape to facilitate the discharge of all the dirt inside. The moving slot 11 penetrates the upper surface to limit the position of the hook 24 to facilitate the placement of the pig carcass in the middle of the cleaning drum 3. The guide plate 13 is used to guide the deviated pig carcass to the inlet 322 of the housing 1. Similarly, the outlet plate 14 is used to guide the deviated pig carcass to the outlet 323 of the housing 1.

[0032] The guide rail 2 is installed above the housing 1 through a fixing frame 21, and a moving groove 22 is provided on the side of the guide rail 2. A moving seat 23 is provided in the moving groove 22, and a hook 24 is hung below the moving seat 23. The hook 24 is hung on one of the hind legs of the pig carcass, and the pig carcass is inverted and driven by the moving seat 23 to move along the moving groove 22 of the guide rail 2, so as to realize the assembly line processing of the pig carcass in the slaughterhouse.

[0033] When in use: first, the hook 24 moves the killed and bled pig to the front of the shell 1 through the moving seat 23 along the moving groove 22 of the guide rail 2, and enters the shell 1 along the inverted eight-shaped guide plate 13 in front of the shell 1, and continues to move inside the shell 1 to the middle of the cleaning drum 3 and stops.

[0034] The steam supply device injects steam into the collecting pipe 35 through the inlet 351 of the collecting pipe 35, and disperses the steam into the various hollow tubes 31 through the various outlets 323 of the collecting pipe 35, and rises along the hollow tube 31 and enters the side spinning nozzle 32, and the spinning jet steam is formed by squeezing the spinning nozzle 32 to rotate to perform all-round jet heating on the pig carcass. After the pig carcass becomes hot, the rotating hollow tube 31 drives the scraper 33 on the outer wall to shave the heated pig carcass.

[0035] After the pig carcass is cleaned of hair, the movable seat 23 drives the hook 24 to lead the pig carcass out of the inside of the shell 1 along the lead-out plate 14, and enters the next step of skinning. At the same time, the steam inlet 351 of the collecting pipe 35 is closed, and the cleaning inlet 351 of the collecting pipe 35 is opened. Warm water is introduced into each hollow tube 31 through the collecting pipe 35, and is sprayed in all directions through the spin nozzle 32 on each hollow tube 31, and each scraper 33 and the inside of the shell 1 are simply rinsed. All the dirt after rinsing is discharged from the drain port 12, and then the next pig carcass is moved in to avoid mutual infection between pig carcasses.

[0036] Furthermore: the shell 1 is set to be a tunnel with a certain length, and enough cleaning rollers 3 are arranged inside it along the processing direction, so as to avoid the moving seat 23 from stopping to wait for processing, and the hair can be shaving while spraying steam during the movement. When the pig carcass moves to the rear to be processed, warm water is sprayed in the front for flushing. When it moves out, warm water is sprayed in the rear for flushing, and the next pig carcass is processed in the front, which can save more time and increase the efficiency of the assembly line.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
