Description

Technical Field

[0001] The utility model relates to the technical field of poultry slaughtering and processing equipment, in particular to a carcass abdominal oil extractor used for automatically stripping off the grease attached to the inner cavity skin of the poultry carcass after evisceration. Background Art

[0002] At present, the carcass belly fat extractor is one of the key equipment in the poultry slaughtering and processing production line.

[0003] The existing methods for automatically stripping the fat attached to the skin of the inner cavity of poultry carcasses after evisceration at home and abroad are mainly the following:

[0004] The first method is to use mechanical clamping after evisceration, such as US Pat. No. 6,726,556B2. The main disadvantages of this method are as follows:

[0005] 1. U.S. Patent: US6726556B2 involves several forms of mechanical clamping mechanisms, which have a common disadvantage: they cannot be fine-tuned according to the size of the poultry carcass. When the size of the poultry changes, the distance from the center of the cavity to the back of the poultry carcass will change. The clamping mechanism has the risk of bruising the sternum or spine of the poultry carcass, which is not allowed in the poultry slaughtering industry.

[0006] 2. Grease is picked up and discharged by the clamping mechanism. The discharge methods include the following:

[0007] 1. Multiple discharge mechanisms are arranged on the side or opposite side of the scraper, and the discharge mechanisms are mainly made of flexible elastic materials. When the scraper passes through the discharge mechanisms, the discharge mechanisms squeeze the grease into the strip-shaped openings arranged on the scraper and discharge it;

[0008] 2. Expel by brushing;

[0009] 3. Discharge with the help of a suction nozzle;

[0010] The disadvantages of the above discharge method are:

[0011] (1) The disadvantages of discharging through the discharging mechanism are:

[0012] Because grease is very sticky, there is a chance that grease will hang on the discharge mechanism or the strip-shaped opening of the scraper. Grease hanging on the discharge mechanism will affect the discharge of grease from the next scraper. Grease hanging on the strip-shaped opening of the scraper not only affects the chance of the scraper removing grease during the next scraping process, but also brings grease into the carcass cavity of the next poultry, causing cross contamination.

[0013] (2) The disadvantages of brushing are:

[0014] Because grease is very sticky, the brush will be covered with grease, which is not only difficult to clean, but also the grease has a flaky structure and brushing with a brush will break the grease into pieces, affecting the quality of the grease and reducing the economic benefits of the slaughterhouse.

[0015] (3) The disadvantages of using a suction nozzle to suck out the grease are:

[0016] Since fat is very sticky, the suction nozzle may be blocked by fat or the flaky fat may be broken into pieces, which not only affects the production process but also reduces the economic benefits of the slaughterhouse.

[0017] The second type, Chinese utility model patent: ZL201821690794.9, also adopts a mechanical clamping form. If the opening of the poultry is too large, the abdominal skin will collapse, and the abdominal fat will be covered by the abdominal skin. When the oil scraper enters the chamber, the abdominal fat and the abdominal skin will be clamped together. At this time, the abdominal skin will be torn off together with the abdominal fat, which not only affects the quality of the peeled fat, but also the falling of the abdominal skin reduces the weight of the carcass, reducing the weight of the carcass and reducing the efficiency of poultry slaughterhouses.

[0018] The third method is to use a spiral drill to twist the pig after evisceration, such as European Patent: EP0258499B1. The disadvantages of this method are that the mechanism is large in size, there is a risk that the mechanism enters the poultry cavity and tears the abdominal skin, which may cause the torn abdominal skin to fall into the removed abdominal fat and there is a risk of the fat being crushed, with the consequences discussed above.

[0053] See also Figure 8-10The gas distribution mechanism 6 in this embodiment includes a connecting shaft tube 12, a gas distribution upper plate 13, a gas distribution lower plate 14, an air guide tube 18, a fixing block 19, a long pin shaft 21, and a gas distribution trigger rod 22; a spring 50, a steel ball 51, a vacuum switch plate 52, and a limit rod 53; the gas distribution upper plate 13 and the gas distribution lower plate 14 are fixed to the central axis 9 through the connecting shaft tube 12, the air guide tube 18 is fixed to the gas distribution upper plate 13 through a threaded connection, the fixing block 19 is connected and fixed to the air guide tube 18 through a top screw, and the gas distribution trigger rod The assembly 22 is connected to the fixed block 19 through a long pin shaft 21 and is evenly arranged under the abdominal oil removal device. The air distribution trigger rod 22 and the fixed block 19 can rotate synchronously with the abdominal oil removal device around the central axis; when the poultry body enters the equipment, this will cause the steel ball 51 to be compressed through the spring 50, causing the air distribution trigger rod 22 to be triggered to move backward, causing the vacuum switch plate 52 to be opened, and when the vacuum switch plate 52 is connected to the notch on the air distribution fixed plate 39 fixed on the air distribution plate 11, it enters the vacuum state.

[0054] Working principle: After the poultry body enters the abdominal oil removal machine, the air distribution trigger rod 22 is triggered to move backwards, causing the vacuum switch plate 52 to be opened, and the abdominal oil removal device begins to descend under the control of the track wheel. During the descent, the dome probe 48 and the clamping guide sleeve 49 of the main oil suction pipe 28 gradually separate. When the dome probe 48 descends to the lowest point, the opened vacuum switch plate 52 is connected to the notch on the air distribution fixed plate 39 fixed on the air distribution plate 11, and enters the vacuum state. At this time, the abdominal oil of the poultry body is sucked between the dome probe 48 and the clamping guide sleeve 49 under the action of the vacuum. The dome probe 48 of the abdominal oil removal device begins to rise gradually under the control of the track wheel. When it rises to the abdominal oil position of the poultry, the dome probe 48 and the clamping guide sleeve 49 clamp the abdominal oil tightly. At this time, the vacuum suction stops. According to the size of the poultry body and the thickness of the abdominal oil, the spring 33 floats up and down, forcing the clamping force of the clamping guide sleeve 49 and the dome probe 48 to match the size of the poultry body, and the abdominal oil is lifted out of the poultry body. The air distribution trigger rod 22 is reset through the reset track device 55 under the action of the limit rod 53, and the poultry carcass moves out of the abdominal oil removal machine along the exit of the turning track 5 to enter the next step.
