DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0037] Please refer to Figures 1-5 The present application provides the following embodiments:

[0038] A processing technology for pre-treating poultry meat food, comprising a scalding and dehairing integrated machine 100 and a poultry meat cutting machine 200, comprising the following processing steps:

[0039] Step one, quality and hygiene inspection is performed on fresh poultry meat, and safe and qualified poultry meat is selected;

[0040] Step two, the selected poultry meat is placed in the scalding tank of the scalding and dehairing integrated machine 100 for 1-3 min, wherein the water temperature of the scalding tank is 60-70 DEG C, and the root of the feather on the poultry meat is softened;

[0041] Step three, the poultry meat soaked in the scalding tank is transferred to the dehairing roller room through the scalding tank of the scalding and dehairing integrated machine 100 until the dehairing is completed;

[0042] Step four, the poultry meat dehaired by the scalding and dehairing integrated machine 100 is adjusted by the arrangement and conveying device 300, and after the head and tail directions of the poultry are adjusted, the poultry meat is conveyed to the poultry meat cutting machine 200;

[0043] Step five, the poultry meat cutting machine 200 cuts the poultry meat after the orientation adjustment to complete the pre-treatment of the poultry meat.

[0044] The arrangement and conveying device 300 comprises a conveying frame 310, equidistantly arranged conveying rollers 320 are rotatably installed on the inner side of the conveying frame 310, a driving motor 330 is fixedly installed on the conveying frame 310, equidistantly arranged transmission wheels 340 corresponding to the conveying rollers 320 are rotatably installed on the conveying frame 310, the adjacent two transmission wheels 340 are driven by a belt, one end of the conveying roller 320 is fixedly connected with the adjacent transmission wheel 340, the output shaft of the driving motor 330 is fixedly connected with the rightmost transmission wheel 340, and the gap between the adjacent two conveying rollers 320 is greater than the maximum width of the head and neck of the poultry and less than the minimum width of the body of the poultry.

[0045] After the poultry is treated by the scalding and dehairing integrated machine 100, the direction of the discharge posture of the poultry is uncertain, after the poultry meat discharged from the scalding and dehairing integrated machine 100 falls on the arrangement and conveying device 300, the driving motor 330 is used as power to drive the conveying roller 320 to rotate and move the poultry meat, and due to the gap limitation between the adjacent two conveying rollers 320, the head and long neck of the poultry can fall into the gap, and the arrangement mode of the poultry is divided into the following two cases:

[0046] 1、The head of the poultry is to the left, and during the conveying process, the head of the poultry can fall to the gap between the two conveying rollers 320 and cannot contact the left conveying roller 320. The right conveying roller 320 continues the conveying process, which can cause the body to turn over, forming a posture of the head hanging down, the body vertical, and the legs upward. The body is affected by the right conveying roller 320 and turns to the left side to contact the left conveying roller 320, and the adjustment of the head to the right is completed.

[0047] 2、The head of the poultry is to the left, and during the conveying process, the buttocks of the poultry move to the left side. Since the gap between the two conveying rollers 320 is smaller than the minimum width of the poultry body, the poultry buttocks, body, and feet will contact the left conveying roller 320 before turning over vertically, and then the left conveying roller 320 will take over the conveying work, and the posture direction of the poultry will not be adjusted.

[0048] The length of the conveying roller 320 is greater than the maximum width of a single poultry body and less than the sum of the widths of two poultry bodies and the length of the poultry body. The top of the conveying frame 310 is fixedly installed with inclined baffles 350 located on the front and back of the conveying roller 320, respectively.

[0049] Due to the length limitation of the conveying roller 320 and the limitation of the two inclined baffles 350, multiple poultry cannot fall onto the conveying roller 320 at the same time for transmission, so that the adjustment and conveying are carried out one by one, reducing the turning work, and the two inclined baffles 350 can avoid the poultry falling onto the conveying roller 320 with the posture of the poultry head forward or backward, ensuring that the poultry can be conveyed in the above two cases.

[0050] The transmission wheel 340 is coaxially fixed by a large pulley 341 and a small pulley 342, and the large pulley 341 and the adjacent small pulley 342 on the left are connected by a belt transmission.

[0051] By changing the connection relationship between the large pulley 341 and the small pulley 342, the transmission ratio between the adjacent two conveying rollers 320 is changed, and the rotation speed of the left conveying roller 320 is always higher than that of the right conveying roller 320. One can facilitate the dispersion of the stacked poultry, and the other can assist the adjustment of the posture direction of the poultry by using the rotation speed difference between the adjacent two conveying rollers 320.

[0052] The conveying roller 320 is sleeved with a silica gel sleeve 321, and the silica gel sleeve 321 is integrally formed with uniformly distributed protrusions. The shape of the protrusions is one of a rhombus, a rectangle, and a triangle.

[0053] The silica gel sleeve 321 sleeved on the conveying roller 320 can protect the poultry meat, and the protrusions can increase the friction between the poultry meat, facilitating the conveying and turning work of the poultry.

[0054] The quality and health inspection mode in step one is one of sensory inspection, microorganism inspection, chemical inspection, test paper inspection and parasite inspection.

[0055] The quality and health of the poultry meat are detected by multiple modes to ensure the safety and reliability of the poultry before pretreatment and ensure that the processed poultry meat meets the quality and health standards.

[0056] The inner side of the conveying frame 310 is fixedly installed with a water collecting plate 360, and the conveying roller 320 is located above the water collecting plate 360.

[0057] Since there is a large gap between the two adjacent conveying rollers 320, it is convenient to control the water of the poultry meat conveyed by the arrangement conveying device 300, and the dripping water is collected by the water collecting plate 360 to avoid pollution.

[0058] The conveying frame 310 is installed with a conveying belt 370 located on the left side of the conveying roller 320, and the conveying speed of the conveying belt 370 is slightly faster than the rotating speed of the leftmost conveying roller 320.

[0059] The conveying belt 370 is arranged to enable the poultry to maintain the adjusted posture after the poultry passes through the conveying roller 320 and is transmitted to the poultry meat cutting machine 200, so as to ensure the stability and convenience of the transportation turnover of the poultry meat cutting machine 200.

[0060] The conveying roller 320 is internally provided with a cavity 322, and the conveying roller 320 is provided with uniformly distributed top rods 323, both ends of the top rod 323 are inserted into the inner wall of the conveying roller 320, the cavity 322 is internally rotatably connected with a limiting cylinder 324, and the weight of the bottom of the limiting cylinder 324 is greater than that of the top, wherein the top of the limiting cylinder 324 is provided with a ventilation hole 325, the back of the conveying frame 310 is fixedly installed with a gas feeding pump 311 and a gas suction pump 312, the gas feeding port of the gas feeding pump 311 and the gas suction port of the gas suction pump 312 are fixedly installed with a communication pipe 313, the gas feeding pump 311 and the gas suction pump 312 are connected with the inside of the cavity 322 through the communication pipe 313, an electromagnetic valve 314 is installed at the connection between the communication pipe 313 and the conveying roller 320, a PLC controller 400 is installed on the conveying frame 310, an infrared sensor 410 is fixedly installed between the bottoms of the two adjacent conveying rollers 320, and the infrared sensor 410 and the electromagnetic valve 314 are electrically connected with the PLC controller 400.

[0061] Because the length of the neck part in the body structure of the chicken, duck, goose and other poultry is relatively long, when the head is turned to the right, the head will not fall to the bottom of the conveying roller 320 during the actual conveying process of the conveying roller 320 and is not detected by the infrared sensor 410, and when the head is turned to the left, the head naturally falls and is easily detected by the infrared sensor 410 because the left side of the head does not timely contact the conveying roller 320. After the PLC controller 400 receives the detection data of the infrared sensor 410, the top rod 323 on the top of the conveying roller 320 on the right side of the corresponding infrared sensor 410 is controlled to be ejected and cooperates with the silica gel sleeve 321 to form a protrusion, thereby assisting the turning work of the poultry body. Compared with the current picture recognition of the complex body structure of poultry, the detection by the low-cost infrared sensor 410 can greatly save the manufacturing cost of the automatic equipment.

[0062] The specific ejection process of the top rod 323 is as follows:

[0063] After the PLC controller 400 receives the detection data of the infrared sensor 410, the two electromagnetic valves 314 installed on the right side of the conveying roller 320 are controlled by the infrared sensor 410. When ejecting, the electromagnetic valve 314 connected with the air conveying pump 311 and the cavity 322 is opened, the electromagnetic valve 314 connected with the air extraction pump 312 and the cavity 322 is closed, the air pressure in the cavity 322 is increased through the connecting pipe 313, and then the top rod 323 is ejected through the air hole 325. When retracting, the electromagnetic valve 314 connected with the air conveying pump 311 and the cavity 322 is closed, the electromagnetic valve 314 connected with the air extraction pump 312 and the cavity 322 is opened, the gas in the cavity 322 is discharged through the other connecting pipe 313, and the top rod 323 is sucked back.

[0064] As described above, the head direction of the poultry can be adjusted during the transportation process by the mechanical structure, so as to facilitate the subsequent cutting and other work, reduce the labor cost, and avoid or reduce the damage to the skin and other parts of the poultry meat by using a simple mechanical structure, thereby reducing the turning cost and difficulty of the poultry meat.

[0065] The above describes only the preferred embodiments of the present application; however, the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical solutions and the improvement concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
