Description

Technical Field

[0001] This invention relates to the field of beef strip processing technology, specifically to a beef strip processing process and equipment. Background Technology

[0002] In the field of beef strip processing technology, traditional production processes mostly employ single-screw extruders to extrude and shape the material. This equipment typically uses a screw propulsion mechanism to force seasoned minced beef through the forming orifice of a front die, thereby forming a strip-shaped product. However, existing screw extruders have several significant drawbacks in practical industrial applications: Limited by the die structure and extrusion pressure distribution, traditional equipment generally suffers from a small number of extrusion orifices and insufficient density of their arrangement, resulting in limited single-pass extrusion output and low production efficiency, making it difficult to meet the needs of large-scale, continuous industrial production. Traditional screw extruders have a relatively simple function, only capable of extruding and molding materials, lacking fixed-length cutting and directional conveying mechanisms. The extruded beef strips are usually cut by a rotating cutter at its end, and the cut material falls or accumulates in a disordered state, increasing the difficulty of manual spreading or sorting in subsequent steaming and drying processes. Excessive accumulation or uneven stress can easily affect the uniformity of heat processing, ultimately damaging the texture, color, and dimensional consistency of the product.

[0003] Therefore, it is necessary to propose a beef strip processing technology and equipment to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved The purpose of this invention is to provide a beef strip processing technology and equipment to solve the problems mentioned in the background art.

The grinding disc has multiple extrusion holes at positions corresponding to the pressure rollers. The slitting and conveying mechanism includes a chain conveyor, wherein multiple scrapers are uniformly fixedly connected to the outer side of the conveying chain plate along its length.

[0006] Preferably, it also includes a support bracket, the top end of the drive shaft is rotatably connected to the support bracket and driven to rotate by a servo motor, and the bottom end of the drive shaft is rotatably connected to the grinding disc.

The drive shaft is driven to rotate by the servo motor. The drive shaft drives the pressure roller to rotate and press the beef mixture into the extrusion hole of the grinding disc. The beef mixture is extruded into strips through the extrusion hole. The extruded beef strips fall onto the conveyor chain of the chain conveyor.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Please see Figure 1-3 As shown, a beef strip processing device includes an extrusion mechanism and a cutting and conveying mechanism. The extrusion mechanism includes a grinding disc 11, with a material collection hood 5 fixedly connected to its top. The top of the material collection hood 5 is connected to a material hopper 3 via a conveying cylinder 4. A drive shaft 2 runs through the middle of the conveying cylinder 4 along its axial direction. The top of the drive shaft 2 is rotatably connected to a support 9 via a bearing and is driven by a servo motor 1. The bottom end of the drive shaft 2 is rotatably connected to the grinding disc 11 via a bearing seat 12. A spiral conveying blade 8 is fixedly connected to the outer side of the middle of the drive shaft 2. Pressure rollers 10 are rotatably connected to both sides of the bottom end of the drive shaft 2. Multiple extrusion holes 14 are opened circumferentially along the grinding disc 11 at positions corresponding to the pressure rollers 10. The cutting and conveying mechanism includes a chain conveyor 6. The conveying speed of the chain conveyor 6 is adapted to the discharge speed of the extrusion holes 14. Multiple scrapers 7 are uniformly fixedly connected to the outer side of the conveying chain plate of the chain conveyor 6 along its length.

[0019] The material to be processed is placed inside the hopper 3. The servo motor 1 outputs power to drive the transmission shaft 2 to rotate around its axis. The transmission shaft 2 synchronously drives the spiral conveyor blades 8 and the pressure roller 10 to rotate. Under the spiral pushing action of the spiral conveyor blades 8, the material in the hopper 3 is continuously pushed to the conveyor cylinder 4 and then transported to the collection hood 5. Simultaneously, the pressure roller 10 applies pressure to the material on the grinding disc 11 during rotation, forcing the material into the extrusion hole 14. Under pressure, the material is extruded into strips through the extrusion hole 14. The extruded beef strips fall onto the conveyor chain of the chain conveyor 6 under gravity and move synchronously with the chain. When the scraper 7 moves with the conveyor chain to the lower end face of the grinding disc 11, it cuts the beef strips extruded from the extrusion hole 14. Through the coordinated operation of its components, the equipment can achieve integrated operation of beef strip extrusion, fixed-length cutting and directional conveying, providing qualified materials for subsequent processing steps. At the same time, the beef strips that are pressed and extruded have a compact structure, which can effectively avoid problems such as loosening and segmentation during subsequent processing, ensuring processing stability and improving product quality.

[0020] Specifically, the fixed position of the spiral conveyor blades 8 on the drive shaft 2 corresponds to the discharge port of the hopper 3 and the inlet of the conveying cylinder 4, ensuring a smooth material conveying path. The bottom end of the conveying cylinder 4 is equipped with a guide block 15 fixedly connected to the drive shaft 2. The guide block 15 reduces the discharge cross-sectional area at the bottom of the conveying cylinder 4, compressing the material during conveying and thus eliminating internal gaps. This design allows for the quantitative and continuous delivery of material to the collection hood 5, preventing material accumulation within the collection hood 5 and ensuring continuous material supply, thereby improving equipment operational reliability.

[0021] In some embodiments, a sleeve 17 is mounted on the outer side of the bottom end of the drive shaft 2 via a key connection. The pressure roller 10 and the sleeve 17 are rotatably connected via bearings. A positioning nut 16 is provided at the top end of the sleeve 17, and the positioning nut 16 is threadedly connected to the drive shaft 2. The positioning nut 16 can be used to position the axial position of the sleeve 17, thereby controlling the gap between the pressure roller 10 and the grinding disc 11, effectively preventing the pressure roller 10 from disengaging from the mating surface of the grinding disc 11 during operation, and ensuring the stability of the material pressing and extrusion effect.

[0022] To improve extrusion efficiency, a tapered feed inlet 13 is provided at the top of the extrusion orifice 14. The tapered feed inlet 13 adopts a flared structure, which can collect and guide the material in the collecting hood 5, improve the feeding efficiency of the material entering the extrusion orifice 14, and thus improve the overall extrusion efficiency.

[0023] In some embodiments, the multiple extrusion holes 14 are staggered along the conveying direction of the chain conveyor 6. By staggering the extrusion holes 14, the beef strips extruded from each extrusion hole 14 can be laid in a single layer when falling onto the conveyor chain of the chain conveyor 6, avoiding the beef strips from stacking together, so as to facilitate subsequent processing.

[0024] The following detailed description of the beef strip processing technology of the present invention is provided in conjunction with specific embodiments. The beef strip processing equipment used in this embodiment is the beef strip processing equipment described above. The specific implementation steps are as follows: Raw material grinding process: Fresh beef or thawed frozen beef is selected as raw material. The tendons, blood vessels, cartilage and impurities in the raw material are removed manually to ensure the purity of the raw material. The pre-treated beef is put into a fully automatic high-speed meat grinder to grind the beef into beef particles with a particle size of 2-5mm; Raw material mixing: The minced beef particles are fed into the mixing equipment, and seasonings are added according to the preset ratio. The mixing equipment is started to mix them evenly; Low-temperature marinating: The well-mixed beef mixture is placed into a marinating container and then placed in a low-temperature cold storage at 0-4℃ for marinating for 4-6 hours. Low-temperature marinating allows the beef fibers to fully absorb the seasoning components, enhancing the flavor profile of the final beef strips, while also inhibiting microbial growth and ensuring the safety of the raw materials. Extrusion and strip forming process: The marinated beef mixture is uniformly placed into the hopper 3 of the equipment, and the material level in the hopper 3 is controlled to always be maintained at 1 / 3-2 / 3 of the hopper volume to avoid insufficient material leading to empty extrusion or excessive material leading to blockage. The servo motor 1 is started, and the drive shaft 2 synchronously drives the spiral conveyor blades 8 and the pressure roller 10 to rotate. Under the spiral pushing action of the spiral conveyor blades 8, the material in the hopper 3 is continuously pushed to the conveyor cylinder 4, and then conveyed to the inside of the collection hood 5 through the conveyor cylinder 4; at the same time, the pressure roller 10 applies pressure to the material on the grinding disc 11 during rotation, pressing the material into the extrusion hole 14. Under the action of pressure, the material is extruded into strips through the extrusion hole 14. The extruded beef strips fall onto the conveyor chain plate of the chain conveyor 6 under the action of gravity and move synchronously with the conveyor chain plate. When the scraper 7 moves with the conveyor chain plate to the lower end face of the grinding disc 11, it cuts the beef strips extruded from the extrusion hole 14. Steaming and drying process: The obtained beef strips are put into a steaming and cooking device to be steamed until cooked. After steaming, the beef strips are put into a drying device to reduce the moisture content of the beef strips to 18-25%.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
