[0036] Such as Figure 1 shown chicken fillet processing method, including the following steps:

[0037] (1) Raw material processing

[0038] Put the chicken breast into a meat grinder and grind it into minced meat. During this time, the ingredient ingredients can also be put into a blender or a meat clamping machine and crushed into smaller granular or powdery forms.

[0039] The ingredient ingredients can be selected from one or more of corn, mushrooms or other mushrooms, kelp or other marine vegetation, vegetable scraps, etc. For the specific weight ratio between the chicken breast and the ingredient ingredients, it is processed according to general principles, that is, the weight ratio of the meat accounts for 1 / 2 to 3 / 4, preferably greater than 2 / 3 (meat / total weight) weight ratio. Specifically, it needs to be determined according to the types of ingredient ingredients used.

[0040] After the minced meat and the ingredient ingredients are both prepared, mix and stir them evenly according to a certain weight ratio, and then mix in the marinade and perform (static) marinating treatment in a low-temperature environment.

[0041] (2) Injection molding and forming,

[0042] Pour the marinated meat filling into a screw conveyor, and continuously transport and pour it into the mold cavity of the mold associated with the outer periphery of the screw barrel. After a certain amount of the meat filling is filled into the mold cavity of the mold, the meat filling is pressed and formed in the mold cavity by the internal pressure of the mold cavity (formed into a long strip-shaped chicken fillet), and finally the formed chicken fillet is thrown out of the mold cavity.

[0043] A plurality of molds can be arranged around the auger cylinder, and the positions of the plurality of molds can be switched to successively establish a communication relationship with the auger cylinder, and a cyclic operation of injecting meat filling, pressing and forming, and throwing the pressed and formed chicken fillets out of the mold cavity is alternately performed among the plurality of molds.

[0044] A plurality of strip-shaped bladder cavities can be distributed at intervals around the inner wall of the mold cavity of the mold. Gas, water or edible oil is injected into the bladder cavities to inflate the bladder cavities, and the bladder walls support the formation of a gap between the surface of the pressed and formed chicken fillets and the inner wall of the mold cavity, and then the mold opening operation is performed to throw the pressed and formed chicken fillets out of the mold cavity.

[0045] Leakage holes can be distributed on the bladder walls of the bladders. When the bladders are inflated, the water or edible oil seeping out of the bladders contacts the surface of the pressed and formed chicken fillets, and then the mold opening operation is performed to throw the pressed and formed chicken fillets out of the mold cavity.

[0046] (3) Coating with batter or breading,

[0047] The pressed and formed chicken fillets are thrown into a batter or breadcrumb tank, and the chicken fillets are tumbled to coat the chicken fillets with batter or breading.

[0048] (4) Refrigerating and packaging,

[0049] The chicken fillets coated with batter or breading are subjected to refrigerating and shape-retaining treatment and then packaged.

[0050] As Figures 2 to 8 shown, a chicken fillet processing device includes an auger conveyor 10, two mold bodies 20, eight molds 30, eight sets of transmission mechanisms 50 and eight power units 40.

[0051] Two feeding holes 14 are evenly distributed at intervals around the wall of the auger cylinder 11 near the conveying end of the auger conveyor 10. The axial direction of the feeding holes 14 is the same as the radial direction of the auger cylinder 11. When the motor 13 drives the auger 12 to rotate, the auger 12 can convey the meat filling fed into the auger cylinder 11 downward and press it into the feeding holes 14.

[0052] On the inner wall of the auger cylinder 11, a guide groove 15 is arranged corresponding to the feeding holes 14, and the arranged guide groove 15 can promote the flow of the meat filling into the feeding holes 14.

[0053] Two mold bodies 20 are symmetrically arranged outside the auger cylinder 11 and correspond to the feeding holes 14 one by one.

[0054] The rotating shaft 24 arranged on the mold body 20 is matched with the driving unit to enable the mold body 20 to rotate intermittently relative to the auger cylinder 11, and the rotation angle each time is 90 degrees. The axial direction of the rotating shaft 24 is the same as and relatively parallel to the axial direction of the feeding holes 14.

[0055] Eight molds 30 are evenly and fixedly arranged on two mold bodies 20, that is, four molds 30 are arranged on each mold body 20. The four molds 30 on each mold body 20 are evenly distributed at intervals around the circumference. As the mold body 20 makes intermittent rotation relative to the auger barrel 11, the ports of the mold cavities 33 of the respective molds 30 on the mold body 20 can rotate and dock with the outer ports of the feeding holes 14.

[0056] Strip-shaped mold cavities 33 are formed on the opposite surfaces between the half molds A31 and the half molds B32 that make up the mold 30, and when the half molds A31 and the half molds B32 are buckled, the two mold cavities 33 can be aligned to form a columnar mold cavity. In specific implementation, a plurality of (slender) strip-shaped (viewed from the view direction looking inwards from the port of the mold cavity 33) capsules 35 can be embedded on the inner wall of the mold cavity 33, such as Figure 4 shown. These multiple capsules 35 are closely arranged around the circumference, and each capsule 35 extends from the port of the mold cavity 33 to the inner bottom surface of the mold cavity 33. The outer wall of the capsule cavity 35a of the capsule 35 facing the outside can basically cover the entire inner wall surface of the mold cavity 33, so that when the meat filling is filled into the mold cavity 33, it is basically in contact with the outer wall of the capsule 35 facing the outside. By controlling the degree of inflation of the capsule cavity 35a, the inner diameter of the mold cavity 33 can be controlled. On the one hand, the surface of the meat filling can be compacted, and on the other hand, after the meat filling is formed / set, a (radial) gap can be formed between the outer wall of the capsule 35 and the outer wall of the formed meat filling (or chicken fillet).

[0057] A plurality of leakage holes can be distributed on the outer wall of the capsule 35. When the capsule cavity 35a expands to a certain extent, a certain medium such as water, edible oil, oil-water mixture, or water vapor filled into the capsule cavity 35a can flow into the mold cavity 33 through the leakage holes and contact the outer surface of the formed meat filling (or chicken fillet) to promote the separation of the chicken fillet from the mold cavity 33 and ensure that the chicken fillet can be smoothly demolded.

[0058] A layer of elastic film layer 34 can be wrapped on the inner wall of the mold cavity 33, and the film layer 34 wraps each capsule 35. The meat filling is directly in contact with the film layer 34 after being transported into the mold cavity 33. The expansion and contraction changes of the capsule 35 can support the film layer 34 to undergo concave and convex changes.

[0059] Eight sets of transmission mechanisms 50, with four sets in each group, are respectively arranged corresponding to the two mold bodies 20. The four sets of transmission mechanisms 50 on each mold body 20 are respectively arranged corresponding to the four molds 30 on the mold body 20. The transmission mechanism 50 has two input ends and two output ends, and two of the output ends are respectively fixedly connected to the half mold A31 and the half mold B32.

[0060] Eight power units 40, with every four as a group, are respectively configured corresponding to two mold bodies 20. Each transmission mechanism 50 is matched with one power unit 40. The power unit 40 is matched with two input ends in the transmission mechanism 50, and can drive the transmission mechanism 50 to act so that the half mold A31 and the half mold B32 are alternately held in the mold closing state and the mold opening state.

[0061] As Figure 2 shown Figure 8 As shown, the transmission mechanism 50 includes a pair of 'L'-shaped arm rods, and the arm rods are divided into two parts, a rod part a51 and a rod part b52, by the bending position. A shaft part 53 is arranged near the bending position of the arm rods. The shaft part 53 is fixed on the mold body 20, and the axial line direction of the shaft part 53 is the same as that of the mold cavity 33. The two arm rods are respectively matched with the half mold A31 and the half mold B32, and the free ends of the rod part a51 are fixedly connected to the half mold A31 and the half mold B32. The free ends of the rod part b52 are matched with the power unit 40, so that the power unit 40 can drive the two arm rods to rotate synchronously around the respective shaft parts 53 to drive the half mold A31 and the half mold B32 to switch between the mold closing state and the mold opening state.

[0062] The power unit 40 is selected as a double-rod cylinder. The double-rod cylinder can be selected to use a double-rod hydraulic cylinder or a double-rod pneumatic cylinder. The double-rod cylinder is fixed on the mold body 20 and is fixed by two brackets 42 as shown in the figure. The brackets 42 are fixed between the bottom plate of the mold cylinder 21 and the end plate 22 at the port of the mold body 20. Pin shafts 41 are arranged at both ends of the two cylinder rods of the double-rod cylinder. Long strip-shaped slot holes 54 extending along the length direction of the rod part b52 are arranged on the two rod parts b52 of a pair of arm rods. The pin shafts 41 at the ends of the double-rod cylinder are respectively inserted into the slot holes 54 on the two rod parts b52. As the cylinder rods of the double-rod cylinder make telescopic movements, the two pin shafts 41 can slide relative to the two slot holes 54 on the pair of arm rods respectively, and push or pull the pair of two arm rods to rotate around their respective shaft parts 53 at the same time.

[0063] When the mold cavity port of the mold 30 is docked with the outer port of the feeding hole 14 on the auger cylinder 11, the half mold A31 and the half mold B32 are held in the mold closing state; as the mold body 20 makes a rotating movement and drives the mold 30 (in the mold closing state) away from the position of the feeding hole 14 on the auger cylinder 11, the half mold A31 and the half mold B32 are switched from the mold closing state to the mold opening state. In the illustrated embodiment, only the uppermost one of the four molds 30 can be docked with the feeding hole 14, and the mold opening is completed only when it rotates to the lowermost position (see as Figure 6 , Figure 8 shown). It can be as Figure 3As shown, when the mold 30 rotates to the lowest position, the mold is opened and the chicken fillet in the mold cavity 33 is thrown onto the conveyor assembly 60 below and transported to the next process. Bran material can be sprinkled on the conveyor assembly 60, and the chicken fillet can adhere to the bran layer after falling on the conveyor.

[0064] A plurality of limit blocks 55 are provided on the mold body 20. The limit blocks 55 are matched with the rod a51 in a one-to-one manner and when the half mold A31 and the half mold B32 move to the end of the stroke in the mold open state, the rod a51 can contact the limit blocks 55. A buffer layer 55b can be fixed on the end face of the limit block 55 facing the rod a51. A cantilever rod 55a can be fixed on the mold body 20, and the limit block 55 is fixed on the free end of the cantilever rod 55a. The axis of the cantilever rod 55a is consistent with the axis of the mold cavity 33. In this way, when the rod a51 hits the limit block 55, a flexible touch and a certain vibration effect can be formed, which is conducive to promoting the shaped filling or chicken fillet to fall off from the mold cavity 33.

[0065] like Figures 2 to 3 ,as well as Figures 5 to 8 As shown, the mold barrel 21 of the mold body 20 is cylindrical, and an end plate 22 is fixed at the end of the mold barrel 21. The various brackets 42 and the various shafts 53 provided in the mold barrel 21 of the mold body 20 are fixed between the bottom plate and the end plate 22 of the mold barrel 21. The rotating shaft 24 passes through the bottom plate and the end plate 22 of the mold barrel 21 and cooperates with the side wall of the auger barrel 11 to support the mold body 20 outside the auger barrel 11. On the side wall of the mold barrel 21, corresponding to the position of the mold 30, long strip-shaped slots 23 are respectively arranged. When each mold 30 rotates to the lowest position as the mold body 20 rotates to the lowest position, the corresponding slot 23 is directly opposite to the bottom of the mold 30, and the chicken fillet in the late stage of the mold opening of the mold 30 can fall out of the mold body 20 from the slot 23.

[0066] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. The present invention can be improved in many aspects without violating the overall concept. Those skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed by the present invention shall be covered by the claims of the present invention.
