Poultry offal taking out device

[0081] Studies have shown that chicken breast bones are relatively smooth, have cartilage tissue, have certain rigidity and strength, and can withstand moderate impacts. The chicken legs are on the top and the neck is on the bottom. The two lobes of the chicken liver are unfolded along the sternum of the cavity. The structure of the viscera harvesting device is reasonable, and the path from the inner side of the chicken breast to the junction of the chest cavity and neck is designed appropriately, which will reduce damage to the viscera, especially the liver.

[0082] Studies have shown that when the evisceration device moves downward, filling moderate temperature water between the liver lobe and the sternum will reduce the friction strength between the evisceration device and the liver, reduce the downward movement of the liver with the evisceration device, and reduce the clipping force. Squeeze and crush the edge of the liver lobe with the holding device. During the evisceration process, the temperature of the chicken is usually 38-39°C, and the injection of water at about 20°C can promote the shrinkage of internal organs and the solidification of fat.

[0083] When the clamping device reaches the junction of the chest cavity and the neck, that is, the bottom of the chest cavity, the water and air channels at the end of the viscera extraction device are converted from water to air, and the moving clamping device and air have an effect on the water at the bottom of the chest cavity Force, similar to the effect of "negative water hammer", exerts pressure on and lifts the viscera as a whole, mainly to put pressure on the back of the chicken to fill the gap between the viscera and the mucous membrane of the back, which is conducive to the upward lifting action of the viscera extraction device Goes smoothly, maintaining the integrity of the internal organs.

[0084] In the short state of food control time, the crop, glandular stomach, and gizzard esophagus are all filled with food, and there is water effect, and the gastroesophagus easily slides into the opening of the opened clamping device. The gastroesophagus mentioned here is a small section of the glandular stomach.

[0085] In the state of long-term food control, the crop, glandular stomach, and gastroesophagus lose water, and the surface is sticky, with the effect of water and air, the bonding force between the gastroesophagus and the cavity mucosa is weakened, and it is easy to slide into the opened clamping device in the opening.

[0086] Experiments have shown that in the state of short food control time, the crop is full of food, and it is difficult to pull the crop out from the neck, requiring a strong clamping force to clamp the gastroesophagus. When the viscera harvesting device is lifted upwards, because the crop is filled with food, it is blocked at the neck, and may be broken at the root of the crop. In this case, the gastroesophagus is also filled with food, among which there may be hard food. During the clamping process of hard food, the pinching fingers will damage the gastroesophagus. At the same time, because the crop is filled with food and blocked at the neck, the force on the gastroesophagus at the clamping position increases, and it is easy to break the damaged gastroesophagus.

[0087] Tests have shown that the use of non-metallic fingers is effective in reducing esophageal fractures in occasions where food control is not standardized, as well as chickens, laying hens, etc. The farming of native chickens is close to natural farming, and hard substances are usually added to the feed for laying hens. Therefore, in the application occasions where food control is not standardized, the gastroesophagus is also filled with food, wherein there may be hard food, and during the clamping process of the hard food, the fingers will have a destructive effect on the gastroesophagus. The pinch finger is made of polyurethane or other plastic materials, which can reduce the rigid extrusion of the gastroesophagus, increase the contact area of ​​the pinch finger with the gastroesophagus, and reduce esophageal rupture, which has a positive effect.

[0088] In one embodiment the fingers are self-adjusting in angle. A shaft is used to install the clamp finger on the clamping end, and the clamp finger can swing slightly around the axis, and its swing range is limited to the gap between the clamp finger and the clamping end joint. The size of the gap determines the angle at which the fingers swing. The swinging posture of the pincers caters to the shape of the gastroesophagus. Under normal circumstances, when there is a hard object in the gastroesophagus, the gastroesophagus will automatically deflect to the upper or lower side of the clamp finger axis, and the clamp finger will automatically adjust its posture to clamp the gastroesophagus. When there is a hard object gastroesophagus above the clamp finger shaft, the upper opening of the clamp finger will be enlarged, and the lower opening will be reduced, so that the gastroesophagus will not fall off after being clamped. When there is a hard object, the gastroesophagus is below the clamp finger shaft, the opening of the lower part of the clamp finger will be enlarged, and will form a combination with the lower pin teeth, and the gastroesophagus will be clamped and will not fall off.

[0089] In one embodiment the fingers are self-adjusting. A shaft is used to install the clamping finger on the clamping end of the fixed arm. Driven by the swing arm, the clamping finger can swing largely around the shaft to form a clamping opening capable of accommodating the gastroesophagus. There is a certain amount of clearance between the gripping finger and the shaft connected to the clamping end, which is sufficient to ensure the amount of movement of the gripping finger. When there is a hard object gastroesophagus above the clamp finger, the gap on the left side of the clamp finger shaft decreases, the upper opening of the clamping mouth increases, and the lower opening of the clamping mouth decreases, so that the gastroesophagus can be clamped and will not fall off. When there is a hard object gastroesophagus under the clamp finger, the gap on the right side of the clamp finger shaft decreases, the upper opening of the clamping mouth decreases, and the lower opening of the clamping mouth increases, so that the gastroesophagus can be clamped and will not fall off.

[0090] In one embodiment, the interfinger tooth and the alveolar form a consistent angle, so as to be suitable for different working conditions.

[0091] In one embodiment, there are gaps on both sides between the interfinger teeth and the alveolar, and the size of the gap is suitable for the gastroesophagus. When the food control is not standardized, the gap should be larger.

[0092] In order to ensure the working effectiveness of the gripper, the gripper must be cleaned every working cycle. The cleaning device adopts high-pressure flushing, and high-pressure flushing adopts mature technology. Make sure that the interdigitated teeth, alveolar and related parts are free from bone residue and visceral mucosa.

[0114] The above-mentioned poultry refers to the appearance and internal organs of a chicken.

[0115] See Image 6 , is an embodiment of the clamping end 32, and the clamping end 32 has a clamping end left part 32-1 and a clamping end right part 32-2.

[0116] See Figure 7 , Figure 13 , the right part 32-2 of the clamping end is provided with a clamp finger 33, and the clamp finger 33 is fixed on the swing arm 17 with a clamp finger shaft 34. There is a clamp finger gap 35 between the clamp finger 33 and the swing arm 17, and the clamp finger 33 is The finger pinch shaft 34 is an axis that freely swings in the pinch finger gap 35 . When the swing arm 17 is pulled apart along the opening direction 36 , the clamping end left part 32 - 1 and the clamping end right part 32 - 2 create an opening 37 for receiving the gastroesophageal tube 105 . The top of the clamping finger 33 is provided with a bar 38 , which is inserted into the groove 39 of the left part 32 - 1 of the clamping end, and the bar 38 slides in the groove 39 .

[0117] See Figure 7 , Figure 8 , said clamp finger 33 is provided with convex teeth 40, when the swing arm 17 is closed along the closing direction 41 (see Figure 8 ), the protruding tooth 40 of the clamping finger 33 is embedded in the groove 39 of the left part 32-1 of the clamping end; the protruding tooth 40 and the groove 39 have angles corresponding to each other, and there is no acute angle, and they will not bite to death after closing.

[0118] See Figure 7 , Figure 13 , the lower end of the clamp finger 33 is provided with a locking hook 42, the locking hook 42 is embedded in the groove 39 in a sliding manner, and has no acute angle, and the right part 32-2 of the clamping end will not bite the groove 39 after closing.

[0119] See Figure 7 , 13 , 19, 22, 23, 24, 25, the left part 32-1 of the clamping end is provided with hook teeth 43, and the hook direction of the hook teeth 43 is towards the spine 113, and its effect is basically similar to that of the hook teeth in the US4435878 embodiment. The spine 113 guides, hooks and guides the gastroesophageal tube 105 into the opening 37 .

[0120] See Figure 7 , 13 , 19, 22, 23, 24, 25, the bottom of the clamping end right part 32-2 of the swing arm 17 is provided with a flange 44, and the bending direction of the flange 44 faces away from the spine 113, and its function is different from that of the hook teeth in the US4435878 embodiment , mainly using the spine 113 guide (see Figure 22 , Figure 23 , Figure 25 ), the gastroesophagus 105 is not hooked, and the gastroesophagus 105 is crossed, so that the gastroesophagus 105 enters the opening 37 of the clamping end 32 smoothly.

[0121] See Figure 9 , the chicken body 100 is the hanging position of the visceral working state. The location of the internal organs is an approximate location, and the location of the internal organs of different chicken breeds is somewhat different. Wherein, the anus 115 has been cut by a rotary cutter and separated from the skin, internal fat and other tissues of the abdomen 120 . The larger shape of the crop 104 is an exaggerated drawing, used to express the irregular situation of food control. Gastroesophagus 105 is an anatomical term specifically named in the present invention, and gastroesophagus 105 is a section of esophagus between the crop 104 and the glandular stomach 106, and is the clamping position specified by the clamping end 32 of the present invention. Before evisceration is performed, the anterior esophagus 103 and trachea 110 should be severed.

[0122] See Figure 9 , 10 From the perspective of the chest 122 of the chicken body 100 to the back 123, the crop 104 of the chicken is on the right side of the bottom 116 of the chest cavity, and the gastroesophagus 105 passes through the spine 113 obliquely to the left and is connected with the glandular stomach 106 of the left chest cavity. Therefore, the timing at which the clamping end 32 reaches the chest bottom 116 should be controlled, and the timing at which the clamping end 32 opens and closes also needs to be controlled.

[0123] See Figure 19 , 23 , 24, 25, the right part 32-2 of the clamping end is opened, and the flange 44 crosses the gastroesophagus 105, and then approaches the spine 113. At this time, the hook teeth 43 catch the gastroesophagus 105 (see Figure 24 ), guiding it into the clamping end opening 37. During the upward pulling process of the device main body 1, the glandular stomach 106, the gizzard 107, the heart 108, and the liver 109 (see Figure 9 , 10 ) under the action of the main body 1 of the device, squeeze each other, and the position will change, especially in the case of irregular food control, the glandular stomach 106, gizzard 107, and intestine 114 are relatively large in shape, and they are lifted up by the main body 1 of the device. During the pulling process, the position of internal organs will change more. In order to ensure the integrity of the liver 109 and the intestine 114, the clamping end 32 adopts a hollow structure to reduce the space occupied by the inner cavity, which can play a positive role. Under the situation that food control is not standardized, crop 104 can not all pull out chicken body 100 abdominal cavity along with viscera bag 125 (see Figure 11 e) is often left in the chicken body 100 to be processed by the decapsler of the subsequent process. According to the requirements of the processing technology, usually, the lung 111 is left in the body cavity. Due to the effect of the hook teeth 43, it is allowed for a part of the left lung and the trachea 110 to be taken out of the cavity. Inspiratory machine treatment of the procedural procedure.

[0124] The viscera bag 125 of the present invention is a collection of viscera taken out from the chicken carcass 100, and is usually not in a scattered state.

[0125] Figure 11 is the working process of the clamping end 32. The premise of visceral extraction is that the anus 115 has been cut by a rotary cutter and separated from the skin, internal fat and other tissues of the abdomen 120 , and the anus 115 and a section of intestine 114 are hung on the cocktail 121 .

[0126] See Figure 11 a, after the chicken body 100 is positioned, the clamping end 32 starts to descend.

[0127] See Figure 11 b, 11c, the clamping end 32 enters the abdomen 120 from the position of the anus 115 . The gripping end 32 moves along the direction of the arrow from the abdominal incision 124 to the chest tip 124 - 1 of the incision, mainly to lift the adhesion between the skin and mucous membrane of the abdomen 120 and the intestine 114 . It is helpful for the intestine 114 to exit the cavity smoothly when the clamping end 32 is lifted.

[0128] Figure 11 d, the clamping end 32 reaches the position of the chest bottom 116 along the chest inner wall 117, the right part 32-2 of the clamping end is opened, and the flange 44 crosses the gastroesophagus 105 (see Figure 25 ), the hook teeth 43 and the flange 44 support the clamping end 32 against the spine 113. At this time, the hook teeth 43 hook the gastroesophagus 105 (see Figure 24 ), the clamping end 32 starts to lift up, and guides the gastroesophagus 105 into the opening 37 of the clamping end, the right part 32-2 of the clamping end is closed, and the gastroesophagus 105 is clamped.

[0129] Figure 11 e, the clamping end 32 is lifted up to remove the viscera bag 125 from the cavity of the chicken body 100 to complete a viscera removal process.

[0130] See Figure 12 , 13 , when the right part 32-2 of the clamping end just reaches the position of the bottom of the chest cavity 116, it opens, and the track groove 9-3 remains horizontal to ensure that the esophagus is in the relative position between the left part 32-1 of the clamping end and the right part 32-2 of the clamping end. The position remains unchanged, reducing the phenomenon of esophageal rupture caused by pulling.

[0131] Figure 13 It is a longitudinal sectional view of the opened state of the clamping end right part 32-2. The swing arm 17 is provided with a clamp finger 33, the clamp finger 33 is fixed on the swing arm 17 with a clamp finger shaft 34, there is a clamp finger gap 35 between the clamp finger 33 and the swing arm 17, and the clamp finger 33 is formed by the clamp finger shaft 34. The axis swings in the gap 35 between the fingers. When the swing arm 17 is pulled apart along the opening direction 36, an opening 37 for accommodating the gastroesophagus 105 is produced between the left part 32-1 of the holding end and the right part 32-2 of the clamping end, and the top of the clamping finger 33 is provided with The blocking bar 38 is inserted into the groove 39 of the end part 32 - 1 , and the blocking bar 39 can slide in the groove 39 .

[0132] Figure 14 , 15 is a schematic view of the clamping end 32 in a closed state. In the case of irregular food control, the clamp finger 33 will automatically adjust its posture to avoid hard materials in the gastroesophagus 105 . When the hard position was close to the stop bar 38, the clamp finger 33 rotated clockwise according to the downward rotation direction 45 (see Figure 16 ), the finger gap 35 decreases above and increases below, clamping the gastroesophagus 105 . When the hard position was close to the lock hook 42, the clamp finger 33 rotated counterclockwise according to the upper rotation direction 46 (see Figure 17 ), the finger gap 35 increases above and decreases below, clamping the gastroesophagus 105 .

[0133] See Figure 16 , 17 , 18, 19, 20, 21, the clamp finger 33 is provided with a convex tooth 40, when the swing arm 17 is closed along the closing direction 49, the convex tooth 40 of the clamp finger 33 is embedded in the groove 39 of the left part 32-1 of the holding end in (see Figure 18 ). The protruding teeth 40 and the grooves 39 have angles corresponding to each other, and there is no acute angle, so they will not bite to death after closing.

[0134] See Figure 18 , in the unloaded state, there is no gastroesophagus 105, and the left part 32-1 of the holding end merges with the pincer 33.

[0135] See Figure 19 , 20 , 21, when the clamping end 32 clamps the gastroesophagus 105, the position of the gastroesophageal tube 105 is in the state of the left part 32-1 of the clamping end and the clamping finger 33.

[0136] See Figure 18, the gap 47 and the gap 48, according to the poultry species, the empirical value determined by the breeding period and the feeding state, must be clamped, and the gastroesophagus 105 cannot be pinched off or broken.

[0137] See Figure 13 , 18 , 19, 20, the left part 32-1 of the clamping end is provided with a groove 39, which has two functions, one is to limit the position of the clamping finger 33 and play a guiding role, and the other is to realize the left part 32-1 of the clamping end. 1 and the right part of the clamping end 32-2 are closed to clamp the gastroesophagus 105, and the groove 39 is designed to be transparent, so that when there is bone residue or meat tissue in the groove 39, the working force of the clamp finger 33 is squeezed It will not be severely affected, and the transparent structure facilitates cleaning.

[0138] See Figure 13 , 16 , 17, the lower end of the clip finger 33 is provided with a locking hook 42, and the locking hook 42 is embedded in the groove 39 in a sliding manner. And there is no sharp angle, it will not bite to death after closing. Its function is to prevent the gastroesophageal tube 105 from falling off from the clamping end 32 when the clamping end 32 is pulled upwards.

[0139] See Figure 19 , 22 , the hook teeth 43 and the flange 44 move upward along the spine 113 to play a guiding role, which is beneficial for the gastroesophagus 105 to enter the opening 37 of the clamping end smoothly.

[0140] See Figure 22 , when the clamping end 32 moves upwards, the hook teeth 43 and the flange 44 work together to ride on the spine 113 and stick to both sides of the spine 113, so as to avoid or less clamp the spine 113 when the clamping end 32 is closed.

[0141] See Figure 23 , the hook teeth 43 and the flange 44 cooperate to guide the gastroesophageal tube 105 into the opening 37 . The lower end of the gastroesophagus 105 is a crop 104, and the upper end of the gastroesophagus 105 is a glandular stomach 106 and a gizzard 107.

[0142] See Figure 24 , the hook of the hook teeth 43 on the left part 32 - 1 of the clamping end is bent towards the spine 113 for hooking the gastroesophagus 105 .

[0143] See Figure 25 a, b, the curvature of the flange 44 of the right part 32 - 2 of the clamping end faces away from the spine 113 , and does not hook the gastroesophagus 105 .

[0144] Figure 23 It is a cross-sectional view of the hook teeth 43 and the flange 44 effectively guiding the gastroesophagus 105 into the opening 37 smoothly.

[0145] See Figure 24 , 25 , the hook teeth 43 hook the gastroesophagus 105, the flange 44 crosses the gastroesophagus 105, and guides the gastroesophagus 105 to enter the opening 37 correctly (see 19, 21, 23). For this reason, the present invention makes the bending direction of the flange 44 toward the spine 113, the clamping success rate is improved. This is one of the key points of the present invention. Otherwise, the hook teeth 43 and the flange 44 hook the gastroesophagus 105 at the same time, the gastroesophagus 105 is blocked inside the clamping end 32, the gastroesophageal tube 105 does not enter the opening 37, the clamping end 32 loses the effect of clamping the gastroesophagus 105, and the internal organs Packet 125 will not be effectively removed.

[0146] See figure 2 , 11 d, when the chicken body 100 is positioned, when the clamping end 32 of the chest presser 5 reaches the position of the bottom end 116 of the chest cavity, the pressing force is moderately relaxed to reduce the damage to the rib 112, so that the flange 44 can pass over the gastroesophagus smoothly 105.

[0147] See Figure 26 , 27 , on the fixed arm 16 and on the swing arm 17, be provided with the water-air passage 50 that can pass water and ventilate, when clamping end 32 stretches in the chicken body 100 cavities (see Figure 27 b), the water-air channel 50 starts to pass water. The temperature of the chicken during viscera extraction is usually 38-39°C, injecting water at around 20°C can promote the contraction of the viscera and the solidification of fat. Water and gas are sprayed out from the left injection port 51 of the left part 32-1 of the clamping end and the right injection port 52 of the right part 32-2 of the clamping end through the water-air channel 50, and flow according to the arrow descending direction 53 (see Figure 27 a). The water can lubricate the liver 109 and reduce the frictional damage of the clamping device to the liver 109 . When the clamping end 32 reaches the position of the bottom end 116 of the chest cavity, the bottom end 116 of the chest cavity and its surroundings will be filled with water at the same time. , gizzard and other visceral organs vibrate with the back of the poultry cavity to loosen, relying on the squeezing effect of water, the viscera bag 125 moves up, and when the swing arm 17 is pulled apart, it is ventilated. Under the action of the water hammer, the water vapor flows along the upward direction of the arrow 54, and the organs continue to move up, allowing the organs and the ribs 112 and the tissues of the dorsal medial 118 to loosen (see Figure 17 b), facilitate the removal of organs. Simultaneously, the swing arm 17 is closed to increase the clamping success rate of the clamping end 32 .

[0148] According to the poultry species and breeding period, the medium of the water-air channel 50 is determined, and the medium is supplied in the form of ventilation, water or air-water mixture. It has greatly improved the situation where the food control time does not meet the standard specifications. It is beneficial for the gastroesophageal tube 105 to enter the opening 37 of the clamping end smoothly, thereby improving the success rate of clamping. Under the action of the negative water hammer, water is filled between the mucous membranes, which is conducive to the smooth lifting of the viscera harvesting device 1 and the integrity of the viscera bag 125 is maintained. For applications where food control is not standardized, as well as native chickens, laying hens, etc., the use of non-metallic fingers is effective in reducing esophageal rupture.

[0149] See figure 1 , The upper end of the turntable 7 is provided with a water vapor distribution plate 12. Be connected with fixed arm 16 and swing arm 17 by pipeline 13, supply water and gas by water-air channel 50 (see Figure 26 ). The time and position of water supply and air supply of the water and air distribution plate 12 are corresponding to the time and position of movement of the clamping end 32 . The present invention adopts the conventional water-air distribution plate technology, and the shower head and the multi-purpose faucet in the bathroom have applications, such as the water spray gun structure of Chinese patent 97217974.7, and the high-grade shower nozzle of Chinese patent 99121447.1 all adopt the same principle.

[0150] See Figure 28 , at a suitable position of the device, a high-pressure flushing device 55 is set. When the clamping end 32 is finished each operation, the high-pressure flushing device 55 flushes the clamping end 32 to remove the bone fragments and bone fragments hanging on the clamping end 32 Succulent mucosal tissue, improving the success rate of each job. High-pressure flushing is a broad concept that can take the form of high-pressure water, high-pressure air, or a mixture of air and water. The high-pressure flushing device 55 of the present invention adopts the mature high-pressure flushing technology at present, and the high-pressure flushing device 55 and its pipeline are designed according to the routine, and can be fixed at a suitable position of the equipment.
