Abstract
Description
Technical Field
[0001] This application relates to food processing equipment, and more particularly to a meat grinder capable of removing hard particles. Background Technology
[0002] A meat grinder is a processing device that can process meat into granular minced meat. Its working process involves the rotation of an auger forcing the meat into corresponding cutter discs and perforated plates for cutting, thus achieving the desired particle size. The perforated plates typically have inner perforations with a large aperture (e.g., 5mm) and outer perforations with a small aperture (e.g., 3mm). After passing through the inner perforated plate, the meat can form hard particles (such as cartilage, bone fragments, tendons, etc.), which can easily clog the outer perforated plate. Summary of the Invention
[0003] In view of this, this application provides a meat grinder that can remove hard particles, thereby reducing the clogging of the outer perforated plate.
[0004] To achieve the above objectives, this application employs the following technical solution:
[0005] A meat grinder capable of removing hard particles, characterized in that it comprises a hopper body, a first auger, a drive mechanism, and a cutting assembly. The first auger is rotatably disposed within the hopper body and is used to transport meat from the hopper body to the cutting assembly. The drive mechanism is used to drive the first auger to rotate. The cutting assembly includes an outer sleeve fixedly mounted on the hopper body and coaxially disposed with the first auger. The first auger can rotate within the outer sleeve. An inner perforated plate and an outer perforated plate are fixedly disposed within the outer sleeve. The outer perforated plate is closer to the outlet of the outer sleeve than the inner perforated plate. The diameter of the through holes on the outer perforated plate is smaller than the diameter of the through holes on the inner perforated plate. A particle-removing cutter disc is disposed between the inner and outer perforated plates, and the particle-removing cutter disc is fixedly connected to the first auger. The de-particle cutter disc, which rotates along with the disc, includes a disc body with multiple circumferentially spaced and axially penetrating material passage holes. A flange protruding axially is fixedly provided next to the outer periphery of each material passage hole, forming a radially extending slot between adjacent flanges. A notch connecting the material passage hole and the slot is provided on the flange. A first discharge hole is also provided on the outer casing, corresponding to the slot position of the de-particle cutter disc. A switch assembly for opening and closing the first discharge hole is also fixedly provided on the outer casing. Under the conveying of the first auger, the meat material first enters the material passage hole of the de-particle cutter disc through the inner perforated plate and then enters the outer perforated plate. Hard particles in the meat material enter the first discharge hole through the slot and are discharged outwards.
[0006] The above-described meat grinder for removing hard particles utilizes a particle-removing cutter disc that rotates with the first auger between the inner and outer perforated plates. This disc removes hard particles (such as cartilage, bone fragments, tendons, etc.) from the meat, reducing the likelihood of hard particles clogging the outer perforated plate. The meat passes directly through the outer perforated plate, while hard particles are discharged from the slot into the first discharge hole. The switching assembly is activated periodically to discharge the hard particles.
[0007] In some embodiments, the cutting assembly further includes a pre-cutting plate, a cutting blade, a bracket, a spacer, and an anti-loosening nut. The pre-cutting plate is fixedly installed inside the outer sleeve and located inside the inner bore plate. The pre-cutting plate has a pre-cutting hole, the size of which is larger than the size of the through hole on the inner bore plate. The cutting blade is installed inside the outer sleeve and located between the pre-cutting hole and the inner bore plate. The cutting blade is fixedly mounted on the first auger and rotates with it. The bracket is fixedly installed inside the outer sleeve and located outside the outer bore plate. One axial end of the first auger is rotatably connected to the bracket. The spacer is fixedly installed inside the outer sleeve and located outside the bracket. The anti-loosening nut is threadedly connected to the outer sleeve and abuts against the spacer to prevent the components inside the outer sleeve from coming out.
[0008] The pre-cutting plate is mainly used to pre-cut the meat, and then the cutting blade further cuts the meat into smaller pieces. The meat is then fed into the inner perforated plate and squeezed into a set size. The meat then enters the outer perforated plate and is further squeezed and reduced to a set size. Finally, it is discharged from the outlet of the outer casing through the gap of the support.
[0009] To ensure that the cutting tools, such as the pre-cutting plate, outer hole plate, and inner hole plate, remain fixed within the outer casing, protruding positioning strips are provided inside the outer casing, and the pre-cutting plate is provided with a locking slot that engages with the positioning strips.
[0010] In some embodiments, the switch assembly includes a fixed base fixedly mounted on an outer casing. The fixed base has a second discharge hole corresponding to the first discharge hole. A discharge pipe corresponding to the second discharge hole is also fixedly mounted on the fixed base. The fixed base also has a vertically movable switch door. The switch door closes the second discharge hole when lowering and opens when raising. A cylinder for driving the switch door's vertical movement is also fixedly mounted on the fixed base. The switch door opens and closes at set intervals.
[0011] In some embodiments, a second auger is rotatably mounted within the hopper body, positioned above the first auger. The hopper body has a disassembly port corresponding to one axial end of the second auger, and a disassembly door for closing this port is detachably connected to the hopper body. This meat grinder, equipped with two augers, improves grinding efficiency. The disassembly port on the hopper body facilitates the removal of the second auger for later maintenance and cleaning.
[0012] In some embodiments, the disassembly door is connected to the hopper body via a rotating snap-fit structure. The disassembly door is equipped with a first handle and a lever for rotating the door. Specifically, the snap-fit structure has a gourd hole on the disassembly door and a locking pin around the outer periphery of the disassembly opening.
[0013] In some embodiments, the meat grinder further includes an isolation cover for blocking the outlet of the outer casing. A fixed shaft is provided on the hopper body, and the isolation cover is rotatably connected to the fixed shaft. During rotation, the isolation cover can block the outlet of the outer casing or move away from it. The function of the isolation cover is to block the outlet of the outer casing, thus reducing the amount of foreign matter entering the meat during feeding, and making it more hygienic and safe. The isolation cover is a rotating structure, making it convenient to use.
[0014] In some embodiments, the isolation cover is also provided with a second handle for rotating it.
[0015] In some embodiments, the front of the hopper body is provided with steps for easy climbing, and the steps are rotatably connected to the hopper body. The steps facilitate loading and observation of the work process, and are foldable for convenient storage.
[0016] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:
[0017] This application discloses a meat grinder capable of removing hard particles. By adding a particle-removing cutter disc that rotates along with the first auger between the inner and outer perforated plates, it can remove hard particles (such as cartilage, bone fragments, tendons, etc.) from the meat, reducing the likelihood of hard particles clogging the outer perforated plate. The meat passes directly through the outer perforated plate, while hard particles are discharged from the slot into the first discharge hole. The switching assembly is activated periodically to discharge the hard particles. Attached Figure Description

The drive mechanism is used to drive the first auger 2 to rotate. The cutting assembly 3 includes an outer sleeve 31 fixedly mounted on the hopper body 1 and coaxially disposed with the first auger 2. The first auger 2 can rotate within the outer sleeve 31. An inner perforated plate 32 and an outer perforated plate 33 are fixedly disposed within the outer sleeve 31. The outer perforated plate 33 is closer to the outlet of the outer sleeve 31 than the inner perforated plate 32. The diameter of the through hole on the outer perforated plate 33 is smaller than the diameter of the through hole on the inner perforated plate 32. A particle-removing cutter disc 34 is disposed between the inner perforated plate 32 and the outer perforated plate 33. The particle-removing cutter disc 34 is fixedly connected to the first auger 2 and rotates with it. The pellet cutting disc 34 includes a disc body 341, on which a plurality of circumferentially spaced and axially penetrating material passage holes 342 are provided. A retaining edge 343 protruding along its axial direction is fixedly provided on the outer periphery of the material passage holes 342. A radially extending slot 344 is formed between two adjacent retaining edges 343, and a notch 345 connecting the material passage holes 342 and the slot 344 is provided on the retaining edge 343.
