[0002] In the key process of pig slaughtering and processing, the scalding and unhairing process plays a decisive role in meat quality and production efficiency, at present, the industry generally adopts the scalding and unhairing pool process, the scalding and unhairing pool using the scalding and unhairing pool process carries out heat transfer with static water body, when pigs are continuously put in, the low temperature of pig body surface and hot water in the pool rapidly exchange heat, causing the temperature in the pool to decrease exponentially, in order to maintain the suitable temperature required for scalding, it is necessary to continuously supplement high-temperature water, so that the energy waste rate is as high as more than 40%, causing great resource loss.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example
[0025] Please see Figures 1-5 This utility model provides a technical solution: an intelligent scalding device for pigs, including an L-shaped mounting frame 100. A feeding mechanism 110 for feeding pigs is installed at the top of one end of the mounting frame 100, and a feeding mechanism 120 for processing pigs is installed at the other end of the mounting frame 100. A high-temperature water mechanism 130 installed inside the mounting frame 100 and capable of outputting water at different temperatures is provided at the bottom of the feeding mechanism 110. A processing box 200 is installed at the top of the mounting frame 100. An inlet 210 is provided on one side of the processing box 200, opposite to the position of the feeding mechanism 110, and an outlet 220 is provided on the other side of the processing box 200, opposite to the position of the feeding mechanism 120. Multiple pig conveying mechanisms 300 are arranged in a stepped manner inside the processing box 200. A spraying mechanism 400 is provided at the top of the pig conveying mechanism 300, which is connected to the high-temperature water mechanism 130 and can spray different high-temperature water according to the needs of scalding and hair removal of pigs.
[0026] Specifically, in actual production, the staff places the slaughtered pigs into the feeding mechanism 110. The pigs enter the processing box 200 through the inlet 210 and move gradually under the action of the pig conveying mechanism 300. During this period, the spraying mechanism 400 continuously sprays hot water at a suitable temperature for scalding. After scalding, the pigs leave the device through the outlet 220 and the delivery mechanism 120, realizing a convenient and intelligent pig processing process.
[0027] In this embodiment: the feeding mechanism 110 includes a first sloping bucket 111 fixedly installed on the top of one end of the mounting frame 100. One end of the bottom of the first sloping bucket 111 is connected to the inside of the inlet 210. A first rubber curtain 112 is fixedly installed on the outer side of the top of the inlet 210.
[0028] Specifically, during use, staff place the pigs on the first sloping hopper 111 or transport them via an automatic conveyor line. Due to the inclination angle of the first sloping hopper 111, the pigs slide smoothly towards the inlet 210 by their own weight. The first rubber curtain 112 fixed to the outside of the top of the inlet 210 can block heat loss from the treatment box 200 and prevent water vapor from overflowing, ensuring efficient use of hot water heat, reducing energy consumption, and also preventing the work area from being filled with water vapor, creating a good working environment for the staff.
[0029] In this embodiment: the delivery mechanism 120 includes a second sloping bucket 121 fixedly installed at the other end of the mounting frame 100. One end of the top of the second sloping bucket 121 is connected to the inside of the outlet 220. A second rubber curtain 122 is fixedly installed on the outer side of the top of the outlet 220.
[0030] Specifically, after the pigs have been scalded in the processing box 200, they are transported by the pig conveying mechanism 300 and then exit from the outlet 220 and fall into the second sloping hopper 121. Similarly, due to the inclined design of the second sloping hopper 121, the pigs will automatically slide down, making it convenient for staff to collect them. The second rubber curtain 122 has a similar function to the first rubber curtain 112, which can prevent a large amount of heat from being lost from the processing box 200 when the pigs are sent out, maintain a stable temperature in the processing box 200, maintain the high efficiency of the scalding work, and prevent water vapor from escaping and causing adverse effects on the working environment.
[0031] In this embodiment: the high-temperature water mechanism 130 includes a frame 131 fixedly installed inside the mounting bracket 100. Two water filters 132 connected to external hot water boilers are installed on the top of the frame 131. The two water filters 132 are connected to an ultraviolet water purifier 134 through a U-shaped pipe 133. The ultraviolet water purifier 134 is connected to multiple hot water booster pumps 136 through a water outlet pipe 135. The water outlet of the hot water booster pump 136 is connected to a temperature control valve 137. The water inlet of the temperature control valve 137 is also connected to a cold water source.
[0032] Specifically, the hot water boiler serves as the hot water source. The hot water first enters two water filters 132, which perform preliminary filtration to remove impurities, particles, and other pollutants. The pre-filtered water then enters the ultraviolet water purifier 134 through a U-shaped pipe 133. The ultraviolet water purifier 134 uses ultraviolet light to sterilize and disinfect the water, further purifying the water quality and ensuring that the water used for scalding is clean and hygienic. The purified water then reaches multiple hot water booster pumps 136 through the outlet pipe 135. The hot water booster pumps 136 increase the water pressure, enabling the water to be smoothly delivered to the temperature control valve 137. The temperature control valve 137 mixes with cold water to adjust the water temperature to a suitable level to meet the needs of scalding and hair removal for pigs.
[0033] In this embodiment: multiple transparent observation windows 230 are installed on both sides of the processing box 200, and the glass of the transparent observation window 230 is provided with a hydrophilic anti-fog coating on both sides.
[0034] Specifically, during the production process, staff can observe the scalding status of pigs in the treatment box 200 through the transparent observation window 230 to determine whether the pigs are being scalded evenly and whether the water spraying mechanism 400 is functioning properly. The hydrophilic anti-fog coating on both sides of the transparent observation window 230 can effectively prevent water vapor from condensing into fog on the glass surface, ensuring that the observation window remains clear at all times.
[0035] In this embodiment: the pig conveying mechanism 300 includes a roller frame 310 fixedly installed inside the processing box 200. Multiple conveying rollers 320 are installed inside the roller frame 310. One end of the conveying roller 320 is equipped with a driven sprocket 330 placed inside the roller frame 310. The multiple driven sprockets 330 are connected to a driving sprocket 340 through a chain. The driving sprocket 340 is driven by a reduction drive motor 350. The reduction drive motor 350 is installed outside the processing box 200.
[0036] Specifically, when the reduction drive motor 350 starts, it drives the drive sprocket 340 to rotate. The drive sprocket 340 drives the driven sprocket 330 to rotate via a chain, which in turn causes the conveyor roller 320 to rotate. The pigs fall onto the top conveyor roller 320 after passing through the feeding mechanism 110. The rotation of the conveyor roller 320 causes the pigs to move within the processing box 200, allowing them to be scalded by the spray mechanism 400 during the stepped movement, thus achieving continuous scalding treatment and improving scalding efficiency.
[0037] In this embodiment: the spraying mechanism 400 includes a pipe network frame 410 fixedly installed inside the treatment tank 200. Multiple electric spray heads 420 are installed at the bottom of the pipe network frame 410. Temperature sensors 430 are installed at the ends of multiple pipes of the pipe network frame 410. The water inlet pipe 440 provided by the pipe network frame 410 is located outside the treatment tank 200, and the water inlet pipe 440 is connected to the outlet of the corresponding temperature control valve 137 through a connecting pipe.
[0038] Specifically, during the scalding process, the water temperature data monitored in real time by the temperature sensor 430 is fed back to the PLC controller in the control box 500. Based on the actual water temperature requirements for scalding the pigs, when the water temperature does not meet the scalding requirements, the PLC controller controls the temperature control valve 137 to adjust the water temperature, and at the same time controls the spray pressure, spray volume and other parameters of the electric nozzle 420. When the temperature sensor 430 detects that the water temperature is too low, the PLC controller will instruct the temperature control valve 137 not to mix cold water and increase the water temperature. When the water temperature is too high, it controls the mixing of cold water to ensure that the scalding water temperature is always suitable and to guarantee the scalding effect.
[0039] In this embodiment: a control box 500 is installed inside the frame 131. A PLC controller with an external power supply is installed inside the control box 500. Multiple temperature sensors 430 are electrically connected to the PLC controller. The PLC controller is also electrically connected to the ultraviolet water purifier 134, the hot water booster pump 136, the temperature control valve 137, the geared drive motor 350, and the electric nozzle 420.
[0040] Specifically, when the temperature sensor 430 reports that the water temperature is too low, the PLC controller will control the temperature control valve 137 to discharge water at the appropriate temperature, and at the same time control the hot water booster pump 136 to increase the water pressure, ensuring that hot water can be supplied in a timely and sufficient manner. The PLC controller can also adjust its speed according to production needs, control the conveying speed of the pig conveying mechanism 300 to match the scalding process, and at the same time, the PLC controller can also control the electric nozzle 420 to adjust its spray angle, frequency and other parameters to ensure that the pigs are scalded in an all-round and uniform manner. Through intelligent control, the automated operation of the device is realized, which greatly improves production efficiency and scalding quality.
[0041] In this embodiment: a hot water collection tank 600 is installed at the bottom of the mounting bracket 100. A return water pipe 610 is installed at one end of the hot water collection tank 600. The return water pipe 610 is connected to one of the water inlets of the hot water boiler through a purification filter and a hot water pump.
[0042] Specifically, when scalding and scalding pigs, the hot water used for scalding can be collected in a hot water collection tank 600. Then, a hot water pump pumps the hot water containing heat into a purification filter for filtration and purification. Finally, the hot water enters the hot water boiler, which can realize the recovery and utilization of the heat of the hot water and make full use of the waste heat.
[0043] Working Principle: In actual production, the slaughtered pigs are placed on the first sloping hopper 111 of the feeding mechanism 110. The pigs slide into the processing tank 200 through the inlet 210 under gravity. The first rubber curtain 112 prevents heat loss and moisture leakage. The external hot water boiler of the high-temperature water mechanism 130 is purified sequentially by the water filter 132 and the ultraviolet water purifier 134. After the hot water is pressurized by the hot water booster pump 136, it is mixed with cold water in the temperature control valve 137 to adjust to a suitable temperature. Inside the processing tank 200, the pig conveying mechanism 300, arranged in a stepped pattern, is driven by the reduction drive motor 350, which rotates the conveyor rollers 320 via a chain, gradually conveying the pigs. The spraying machine... The electric nozzle 420 of the structure 400 sprays hot water of appropriate temperature onto the pigs based on feedback from the temperature sensor 430 and controlled by the PLC controller. After scalding, the pigs slide out from the outlet 220 through the second sloping hopper 121. Compared with the traditional scalding tank process, this device solves the problem of low temperature control efficiency. Through dynamic scalding and intelligent temperature control, the heat transfer efficiency is increased to 78%, and the unit energy consumption is reduced by 65%. It avoids the enrichment of biological contamination, reduces the microbial contamination of meat products by 90%, reduces human intervention, and increases the full automation rate to 95%. It effectively ensures meat quality, reduces cross-infection, and improves production efficiency. At the same time, it can also recover and utilize the waste heat of the hot water.
