Description

Technical Field

[0001] This invention belongs to the field of yak jerky processing technology, specifically relating to a yak jerky processing equipment and method. Background Technology

[0002] Existing literature CN101023796B1 discloses a method for preparing yak jerky, including meat selection, rinsing, cutting, braising, slicing into strips / pieces, stir-frying, cooling, mixing with seasonings, sterilization, inspection, and packaging. However, this conventional preparation method cannot produce yak jerky with meat floss attached. Summary of the Invention

[0003] In order to solve at least the technical problems mentioned in the background art, the present invention aims to provide a yak jerky processing equipment and method.

[0004] The present invention adopts the following technical solution.

[0005] A yak jerky processing device includes a wrapping mechanism, a steaming mechanism, a kneading mechanism, and a blower drying box, all arranged on a circular production line. The wrapping mechanism is used to linearly pack yak meat strips into flexible bags and drive the yak meat strips to move in each module according to a set pattern. The flexible bags are long, strip-shaped fabric bags with a strip-shaped opening at the top.

[0006] In order to more smoothly produce yak jerky with meat floss directly attached to the jerky, the flexible material bag is made of gauze with a pore size of 0.3mm~0.4mm.

[0007] Furthermore, the wrapping mechanism includes a base mounted on a transverse track, on which two sets of opposing cylinders are mounted. The front ends of the telescopic rods of the two cylinders are fixedly connected to the ends of the flexible material bag. Initially, the flexible material bag is in a flat and relaxed state without tension. When the telescopic rods of the two cylinders retract, the flexible material bag is in a taut and reduced-diameter state. When the telescopic rods of the two cylinders extend, the flexible material bag is in a bent state. Using this design, without affecting the shaping of the yak meat strips, it is possible to quickly place the yak meat strips into the fabric bag and quickly remove them from the fabric bag.

[0008] Furthermore, the wrapping mechanism also includes a rotating assembly, on which two sets of cylinders are mounted. The rotating assembly can drive the cylinders to rotate and tighten the flexible bag.

[0009] Furthermore, the kneading mechanism includes a fixed plate and a movable plate. Both the top surface of the fixed plate and the bottom surface of the movable plate have a roughened structure. The movable plate is connected to a lateral reciprocating motion mechanism, which is connected to a lifting mechanism. When the flexible bag containing yak meat strips moves between the fixed plate and the movable plate, the movable plate presses against the flexible bag and reciprocates. Preferably, the fixed plate and the movable plate are made of stainless steel, and the roughened structure is a laser-clad layer. Using this method, a meat floss layer can be quickly and directly prepared on the surface of the yak meat strips.

[0010] A method for processing yak jerky using the aforementioned yak jerky processing equipment, comprising the following steps: Step 1: When the flexible bag of the wrapping mechanism moves to the filling station, control the two sets of cylinders to make their telescopic rods in the initial state. At this time, the strip opening opens and fresh yak meat strips are put into the flexible bag. Step 2: Control the movement of the two sets of cylinders to retract their telescopic rods. At this time, the flexible material bag is in a state of being stretched and reduced in diameter. Then, control the movement of the rotating component to drive the cylinder to rotate and tighten the flexible material bag. Then, control the flexible material bag to move to the steaming mechanism to steam the yak meat strips inside the flexible material bag. Step 3: After the yak meat strips are steamed, the flexible bag is dried and then moved between the fixed plate and the movable plate of the kneading mechanism. Finally, the transverse reciprocating motion mechanism is controlled to run in the set manner to repeatedly knead the flexible bag. Step 4: After the kneading process is completed, control the rotating component to reset (restore the flexible bag to its state before tightening), and move the flexible bag to the blower drying box for air drying; Step 5: Control the movement of the two sets of cylinders to extend their telescopic rods. At this time, the flexible bag is in a bent state and the strip opening is in an open state. Then, take out the dried meat from the flexible bag. The dried meat has meat floss on the surface.

[0011] Preferably, in step 2, steam is used to steam the yak meat strips inside the flexible bag; in step 3, the temperature in the forced-air drying oven is controlled at 20~25°C, and the relative humidity is controlled at 14~16%. Preferably, in step 2, the steaming time is controlled at 8~11 minutes.

[0012] Beneficial effects: The solution of this invention can not only produce yak jerky with meat floss directly attached to the jerky, but also grow meat floss evenly on the surface of the yak jerky. The resulting yak jerky also has the advantage of being easy to tear by hand. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0015] Combination Figures 1 to 4 As shown, a yak jerky processing device includes a wrapping mechanism 1, a steaming mechanism 2, a forced-air drying chamber 3, and a kneading mechanism 4, all arranged on a circular production line. The wrapping mechanism 1 is used to linearly load yak meat strips 5 into flexible bags 10 and to move the yak meat strips 5 in each module according to a set pattern. The flexible bags 10 are long, narrow fabric bags with a strip-shaped opening 11 at the top. The flexible bags 10 are made of gauze with a pore size of 0.3mm to 0.4mm.

[0016] In this embodiment, combined with Figure 2 As shown, the wrapping mechanism 1 includes a base 12 mounted on a track 6 (track 6 of a circular production line). Two sets of opposing cylinders 13 are mounted on the base 12, with the front ends of the telescopic rods of the two cylinders 13 fixedly connected to the ends of the flexible bag 10. Initially, the flexible bag 10 is in a flat, relaxed state without tension. When the telescopic rods of the two cylinders 13 retract, the flexible bag 10 is stretched and its diameter is reduced. When the telescopic rods of the two cylinders 13 extend, the flexible bag 10 is in a bent state. The wrapping mechanism 1 also includes a rotating assembly 14, on which both cylinders 13 are mounted. The rotating assembly 14 can drive the cylinders 13 to rotate and tighten the flexible bag 10. The rotating assembly 14 includes a motor and a turntable connected to its output end, with the cylinders 13 fixedly mounted on the turntable.

[0017] In this embodiment, combined with Figure 3 As shown, the kneading mechanism 4 includes a fixed plate 41 and a movable plate 42 (the fixed plate 41 is stationary relative to the movable plate 42 during the kneading process, meaning only the movable plate 42 reciprocates). Both the top surface of the fixed plate 41 and the bottom surface of the movable plate 42 are provided with a rough structure 45. The movable plate 42 is connected to a lateral reciprocating motion mechanism 43, which is connected to a lifting mechanism 44. When the flexible bag 10 containing yak meat strips 5 moves between the fixed plate 41 and the movable plate 42, the movable plate 42 presses against the flexible bag 10 and reciprocates. The fixed plate 41 and the movable plate 42 are made of stainless steel, and the rough structure 45 is a laser-clad layer.

[0018] A method for processing yak jerky using the yak jerky processing equipment described in this embodiment, for preparing original flavor yak jerky, includes the following steps: Step 1: When the flexible bag 10 of the wrapping mechanism 1 moves to the filling station, the two sets of cylinders 13 are controlled to move their telescopic rods to the initial state, at which time the strip opening 11 opens (as shown in the image). Figure 2 As shown), fresh yak meat strips 5 are put into the flexible bag 10. Fresh yak meat strips 5 refer to strips of yak meat that have been cut and marinated according to size requirements. Step 2: Control the two sets of cylinders 13 to retract their telescopic rods. At this time, the flexible bag 10 is in a taut and reduced diameter state (the strip opening 11 is slightly closed). Then, control the rotating component 14 to drive the cylinders 13 to rotate and tighten the flexible bag 10 (the state at this time is as follows). Figure 4 As shown, the strip opening 11 is completely closed and "locked"); then the flexible bag 10 is moved to the cooking mechanism 2 to cook the yak meat strips 5 inside the flexible bag 10. Specifically, steam at normal pressure is used to cook the yak meat strips 5 inside the flexible bag 10, and the cooking time is controlled at 10 minutes. Step 3: After the yak meat strips 5 are steamed, the flexible material bag 10 is dried (drying temperature is 50℃, time is 10 minutes, the purpose is mainly to dry the flexible material bag 10 so that it is more conducive to the formation of meat floss on the surface of the yak meat strips 5 later). Then it is moved between the fixed plate 41 and the movable plate 42 of the kneading mechanism 4. Finally, the transverse reciprocating motion mechanism 43 is controlled to run in the set way to repeatedly knead the flexible material bag 10. During this process, the strip opening 11 is still in a completely closed and "locked" state. Specifically: First, control the cylinder connected to the fixed plate 41 to move the fixed plate 41 to the target position. Then, control the lifting mechanism 44 to move the movable plate 42 to the target position. Next, wait for the flexible bag 10 to move between the fixed plate 41 and the movable plate 42. Then, adjust the lifting mechanism 44 to press the flexible bag 10 down. Finally, control the transverse reciprocating motion mechanism 43 to drive the movable plate 42 to reciprocate, thereby repeatedly rubbing the flexible bag 10. The frequency of the reciprocating motion of the movable plate 42 is controlled at 180 times / minute, that is, there are three complete rubbing cycles per second, and the time is controlled at 3 minutes. Step 4: After the kneading process is completed, control the rotating component 14 to reset and restore the flexible material bag 10 to the state before tightening (at this time, the strip opening 11 returns to a slightly closed state). Move the flexible material bag 10 to the forced-air drying box 3 for air drying (the purpose is to obtain dried beef jerky). The temperature in the forced-air drying box 3 is controlled at 20~25°C and the relative humidity is controlled at 14~16%. Step 5: Control the movement of the two sets of cylinders 13 to extend their telescopic rods. At this time, the flexible material bag 10 is in a bent state and the strip opening 11 is in an open state. Then, take out the dried meat from the flexible material bag 10. The dried meat has meat floss on the surface.

[0019] Example 2, a meat jerky processing method using the yak jerky processing equipment in this example, differs from Example 1 in that: the flexible material bag 10 is made of cotton cloth without through holes.

[0020] Example 3, a meat jerky processing method using the yak jerky processing equipment in this example, differs from Example 1 in that: boiling water at normal pressure is used to steam the yak meat strips 5 in the flexible material bag 10, and the steaming time is controlled at 10 minutes.

[0021] Example 4: A method for processing yak jerky using the yak jerky processing equipment in this example, which differs from Example 1 in that the steaming time is controlled at 3 minutes.

[0022] Example 5: A method for processing yak jerky using the yak jerky processing equipment in this example, which differs from Example 1 in that the steaming time is controlled at 30 minutes.

[0023] Using the method in Example 1, yak jerky with meat floss directly attached to the jerky can be prepared, and meat floss (such as...) grows evenly on the surface of the yak jerky. Figure 5 As shown), the resulting yak jerky also has the advantage of being easy to tear by hand, and can be torn into small strips of meat. Using the methods in Examples 2 and 3, yak jerky with a small amount of meat floss directly attached to the jerky can be prepared, but the meat floss is sparsely distributed (analysis suggests the reasons include: the yak jerky corresponding to Example 2, such as...). Figure 6As shown, the friction mainly occurred between the yak jerky and the flexible material bag; in Example 3, the yak meat strips were soaked in more water and the meat was relatively firm, which is considered friction under a moist state, and the corresponding yak jerky is as follows. Figure 7 As shown, the meat floss is too long); using the methods in Examples 4 and 5, it is impossible to prepare yak jerky with meat floss directly attached to the jerky, and the edges of the meat strips are raised (as shown). Figure 8 As shown), especially in Example 5, the yak meat strips are prone to cracking during the kneading process (e.g. Figure 9 As shown in the image, the meat is difficult to tear into thin strips by hand.

[0024] One key aspect of this invention is the use of a flexible material bag with a specific structure and a kneading mechanism, along with specific operating steps, to produce yak jerky with meat floss directly and evenly attached to the jerky, making it easy to tear by hand. Another key aspect is the use of steam to cook the yak meat strips inside the perforated flexible material bag, solving the problem that the yak meat strips are prone to being wet during the kneading process, making it difficult to generate meat floss.
