Technical Field
[0001] This utility model relates to the technical field of meat floss impurity separation, specifically a meat floss impurity vibration separation device. Background Technology
[0002] With modern families placing increasing emphasis on the nutrition and health of infants and toddlers, the infant and toddler snack food industry has experienced rapid growth in recent years. Infant and toddler snack foods refer to nutritional foods specifically designed and processed for infants and toddlers aged 0-6 years, used to supplement nutritional deficiencies in their daily diet or as complementary foods at specific stages. There are many types of infant and toddler snack foods, including rice cereal, noodles, fruit puree, vegetable puree, and meat floss. Among them, meat floss, as a high-protein, high-nutrient complementary food, is particularly popular with parents and infants due to its unique taste and nutritional value.
[0003] As a special type of complementary food, infant meat floss has strict requirements for its production and testing. First, the selection of raw materials must strictly adhere to food safety standards, ensuring no additives, pesticide residues, or heavy metal contamination. Second, the processing requires advanced production technology and equipment to ensure the meat floss has a delicate texture and is easily digestible. However, during the production of meat floss, impurities such as bone fragments, tendons, fat lumps, and debris generated during production are often introduced. These impurities not only affect the quality and taste of the meat floss but may also pose a potential threat to the health of infants and young children.
[0004] Currently, the main methods for separating impurities from meat floss include manual selection and vibrating screen. Manual selection is inefficient and labor-intensive. While vibrating screen can improve efficiency, some small or irregularly shaped impurities can become trapped inside the meat floss. Vibration can separate them, but the separated impurities are small in size and mass; some fall through the screen, while others fall back onto the top of the meat floss, making it impossible to remove them with vibration alone, resulting in unsatisfactory screening results. Given the various problems with existing meat floss impurity separation methods, developing a novel meat floss impurity separation technology is particularly important. By combining vibration and jumping, the material can be made to move relative to each other under the action of vibration force, thereby achieving material separation and screening. Specifically, the meat floss raw material is first fed into a vibrating screen bed. Driven by a vibration mechanism, the screen bed vibrates up and down, causing impurities to separate from the meat floss. An airflow separation device then operates, using airflow to blow away the impurities that were originally trapped within the meat floss. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Please refer to Figures 1-7, which show one embodiment of this utility model:
[0027] Vibrating screening machine frame and screening plate design:
[0028] Support legs 2 are welded and fixed to the left and right sides of the front and rear ends of the vibrating screening machine frame to ensure stable placement of the equipment. A feed guide plate 3 is fixed to the upper end of one side of the machine frame, and a rubber plate is fixed to one end to adhere to the fifth screening plate to prevent meat flakes from overflowing. A discharge guide plate 4 is fixed to the lower end of the other side of the machine frame and is fixed to the elastic baffle plate at the lower end of the fifth screening plate to facilitate the discharge of meat flakes.
[0029] The vibrating screening frame 1 contains, from left to right, a first screening plate 5, a second screening plate 6, a third screening plate 7, a fourth screening plate 8, and a fifth screening plate 9, arranged in a stepped configuration from top to bottom. Each screening plate has several screening holes 24 for separating impurities. The four corners of the lower end of each screening plate are connected to the lower surface of the vibrating screening frame via spring support rods 10 to achieve the vibration effect.
[0030] Elastic baffles 11 are fixed between the screening plates and at the lower end of the outer side of the fifth screening plate to prevent impurities from splashing into the impurity conveying area.
[0031] The screening plate can vibrate up and down to promote the separation of impurities in the meat floss, while the multi-stage screening and stepped arrangement ensure the effective removal of impurities.
[0032] Airflow control system:
[0033] The exhaust duct 12 is embedded in the elastic baffle plate 11, with an exhaust branch duct 13 installed in the middle of one side. Multiple exhaust branch ducts are connected and converged through the exhaust main duct 14, the other end of which extends to the outside of the vibrating screening machine frame. The external blowing structure blows air, which is discharged from the exhaust duct 12 through the exhaust main duct 14 and the exhaust branch ducts 13. By precisely controlling the airflow, impurities in the meat floss are further blown away, improving the purity and quality of the product.
[0034] Impurity conveyor belt and transmission system:
[0035] A first drive motor 15 is installed at the lower rear end of the vibrating screening frame. Drive rollers 16 are equidistantly installed inside the lower end of the frame, with one of the drive rollers connected to the output shaft of the first drive motor. A conveyor belt 17 is externally connected to the drive rollers, and outer protective barriers 18 are fixed at the front and rear ends of the conveyor belt to prevent meat flakes and impurities from falling off. The stable transmission system ensures the stable operation of the conveyor belt, smoothly conveying the screened impurities out of the equipment.
[0036] Vibration drive mechanism:
[0037] A central rotating shaft 20 is rotatably connected to the lower end of the screening plate inside the vibrating screening frame. Rotating cams 21 are fixed to the front and rear ends of the central rotating shaft, and these cams are in contact with the screening plate. A second drive motor 19 is installed at the rear end of one of the central rotating shafts, driving the central rotating shaft to rotate. The front end of the central rotating shaft passes through the front end face of the frame and is fixed with a front drive wheel 22. Multiple front drive wheels are driven by a front drive belt 23.
[0038] Driven by the second drive motor, the screening plate vibrates up and down, effectively promoting the separation of impurities from the meat floss.
[0039] Impurity collection system:
[0040] The vibrating screening frame 1 has a collection box 25 installed at its upper end. The lower end of the collection box 25 is stepped, and a screen plate is fixed to the lower end of the collection box 25. A connecting pipe 26 is installed at the upper end of the collection box 25, which communicates with the inside of the collection box and is used to collect impurities separated by vibration and airflow. When the external exhaust structure is working, the impurities vibrated out are output through the connecting pipe 26.
[0041] Working principle: The meat flakes reach the upper end of the first screening plate 5 through the feeding guide plate 3; the second drive motor 19 drives one of the central rotating shafts 20 to rotate, and the front drive wheels 22 at the front ends of multiple central rotating shafts 20 rotate together through the transmission relationship of the front drive belt 23. Multiple rotating cams 21 rotate and indirectly impact the first screening plate 5, the second screening plate 6, the third screening plate 7, the fourth screening plate 8 and the fifth screening plate 9, causing the meat flakes at the upper end of the first screening plate 5, the second screening plate 6, the third screening plate 7, the fourth screening plate 8 and the fifth screening plate 9 to jump, so that impurities are separated from the wrapping of the meat flakes. Some impurities reach the upper end of the conveyor belt 17 through the screening holes 24 and are conveyed out by the rotation of the conveyor belt 17.
[0042] At the same time, the external blowing structure blows out airflow, which is discharged from the exhaust pipe 12 through the exhaust main pipe 14 and the exhaust branch pipe 13, blowing away the impurities in the vibrating meat floss; at the same time, the external exhaust structure works, and the vibrated impurities enter the collection box 25 through the lower end of the collection box 25 and are output through the connecting pipe 26.
