Definitions

  • the invention relates to a poultry slaughtering and processing equipment, in particular to a poultry viscera taking out device.
  • automated viscera processing generally uses mechanical devices to grab or wrap the viscera from the inner cavity of the poultry close to the root of the neck, and take the viscera out of the inner cavity of the bird.
  • the circular viscera picking tool plays the role of positioning and hooking the esophagus, improving the integrity of internal organs.
  • the circular viscera picking tool has simple movement trajectory and mechanism. Under normal circumstances, the organs taken out will be scattered and hung on the outside of the back of the bird's body, and then the organs are separated from the bird's body manually. This type of visceral collection is still in use today.
  • the visceral device has begun to adopt the form of clamping and taking esophagus.
  • the removed internal organs are separated from the carcass and can be transferred to other conveying equipment.
  • EP0539134A1 (1989) a simple gripping tool with the function of gripping the esophagus was disclosed.
  • the visceral device has fingers on the head, which are equivalent to the hook teeth of US4435878 (1982), which mainly serve to locate and hook the esophagus.
  • the upper end of the grasping tool in EP0539134A1 (1989) has a large space, no restriction on the esophagus, and poor orientation to the esophagus.
  • the position of the esophagus cannot be fixed, and the success rate of esophageal clamping is not high. It is not certain that the gripping tool hugs the internal organs, and the organs removed will be scattered and hung on the outside of the back of the bird's body.
  • a straight-handled esophageal clamping device is disclosed.
  • the head of the clamping device is hinged and the clamping block is opened and closed by a pull rod.
  • the opening and closing are connected by a hinge, and the position of the hinge can limit the upward movement of the esophagus and prevent the esophagus from separating from the clamping head.
  • the straight-handled esophageal holding device whether inserted from the chest or back, will occupy a part of the main body of the organ during insertion into the cavity and withdrawal process, which will cause damage to the liver or intestines.
  • WO2009/020465A1 it is also a straight-handled esophageal clamping device, which is a double-sided clamping form.
  • a rotating arm type esophagus holding device which extends from the inner wall of the chest into the abdominal cavity and reaches the position of the neck of the internal cavity of the bird.
  • the rotating arm is turned along the chest wall to the dorsal wall , Clamp the esophagus, lift and remove the internal organs.
  • This method has a positive effect on reducing liver damage.
  • this structure only realizes the separation of the internal organs and the carcass, and the removed internal organs cannot be effectively transferred to other conveying equipment.
  • the structure is optimized, but the working mode is basically unchanged.
  • the rotating arm is in a closed state, which makes the whole organ unstable during the upward pulling process, and the removed internal organs are easy to scatter.
  • a visceral removal device in the form of a crank arm is disclosed.
  • the visceral removal device has two crank-shaped swing arms, which are called “pulling arms" in EP2314169A1 (2001).
  • the two swing arms are inserted into the abdominal cavity along the inside of the chest of the bird at the same time. When they reach the inner cavity of the bird near the base of the neck, one of the arms swings in one direction.
  • the clamping device forms a channel. When the arms move upward, the esophagus enters the channel. The arm swings back in one direction, merges the clamping device, clamps the esophagus, and takes out the internal organs.
  • a stop bar is added to the end of the clamping device to limit the upward movement of the esophagus. Its working method is similar to the vernier caliper often used in our machinery industry. , The fat measuring rule commonly used in the food industry and health care, such as US5156161, is also similar to the pliers commonly used in the medical industry, such as US4318313. These technologies have long been widely used.
  • the advantage of the clamp-type viscera removal device is that the clamped viscera can be transferred to another conveying line by means of transfer.
  • the shape of the curved part does not interfere with the abdomen of the bird.
  • the two lobes of the liver overlap, and the lobules are different in length from the large lobes.
  • the head of the holder is too narrow and may be inserted into the gap between the two lobes of the liver, which is not conducive to protecting the liver.
  • the material of the wings on both sides of the spoon has been upgraded, using elastic materials.
  • the function of the evisceration spoon is basically the same as that of CN106572668B and CN202999192U, mainly to ensure the integrity of internal organs.
  • the working forms of the implementation schemes published in WO2005/104858A1 (2004) and RU2262238C2 (2004) are basically similar.
  • the visceral device adopts the same working method as US3979793 (1974), enters the cavity from the inside of the chest, and hooks the esophagus with the hook teeth.
  • the difference from US7976367B2 (2007) is that a rod extends into the back, and the rod contacts the hook teeth to clamp the esophagus.
  • the hook form is to hook the esophagus by pulling, and then press the esophagus with the evisceration spoon.
  • the larger area of the flanks takes up some space of the internal organs, which will inevitably cause the internal organs to be squeezed.
  • the liver will be damaged. It is also possible that the flanks do not coincide with the liver, cutting off the ends of the liver.
  • the clamping device only wraps the internal organs, which is not good for the overall protection of the internal organs.
  • the key to automatic viscera removal is the clamping device.
  • the requirement is not to damage the liver, but also to be able to clamp the esophagus, keeping the viscera intact and take it out of the internal cavity of the bird.
  • operators often cannot follow the standard of "fasting time should be controlled within 6h-12h, and drinking water should be guaranteed".
  • the research results show that if the fasting time is insufficient, there will still be feed in the poultry's croak, glandular stomach and muscular stomach at the time of slaughter.
  • the full mouth and intestines are easily damaged during evisceration, and there is a higher risk of contamination.
  • the pellet or stone feed in the esophagus stays unevenly in the esophagus.
  • the opening In order to fully accommodate the esophagus in the opening of the clamping device, the opening needs to have a certain length. A large included angle is formed when the esophagus is held closed, and the esophagus cannot be fully clamped. It is easy to clamp the esophagus, and the esophagus breaks and falls off during the lifting process. Prolonged fasting time, due to dehydration, will cause the intestines to become fragile and easy to break.
  • the dehydrated clams will be firmly attached to the abdominal cavity, and the pulling force needs to be increased during lifting, which increases the rupture of the esophagus, especially the gastroesophagus between the musculostomia and the glandular stomach, and increases the residual rate of the heart or gizzards and other organs.
  • the way that the device for taking out poultry viscera moves along the inner wall of the chest and extends into the thoracic cavity is more advantageous for the operation of taking viscera.
  • the swing arm structure in the form of a crank is restrictive to the body shape of the poultry.
  • the swing angle is large, causing damage to the internal cavity of the bird.
  • the swing angle is small.
  • the body shape of some birds varies from time to time.
  • the chick is on the lower right side of the bird's body.
