Description

Technical Field

[0001] The invention relates to the technical field of meat jerky processing, in particular to a mixing and stirring device and a stirring method for meat jerky processing. Background Art

[0002] Meat jerky is a cooked meat jerky food made from livestock and poultry meat as the main raw material, seasoning and auxiliary materials, and then baked and cooked. The general processing procedures of meat jerky are: raw material thawing, pre-bleaching, cleaning, trimming, cutting, slicing, sorting, re-slicing, drying, stirring and marinating, baking, cooling, packaging, and finished product storage. In the whole process, the maturity of the stirring and marinating process is an important part of determining the taste of meat jerky. The stirring and marinating of meat slices is usually carried out in a stirring device. The meat slices and seasonings are added to the stirring container and mixed together using the stirring structure. The best state is that the seasoning is evenly applied on the surface of the meat slices.

[0003] However, in the actual mixing process, affected by the humidity and oil content of the meat slices and the temperature in the mixing drum, if the meat slices are too moist or have too much oil, they are easy to stick together during the mixing process, which may cause some meat slices to not fully contact with the spices. Similarly, when the temperature in the mixing drum is too high, the fat in the meat slices is easy to melt, which will also make the surface of the meat slices more greasy, thereby increasing the adhesion between the meat slices, causing them to stick together easily. When the contact area between the meat slices and the spices becomes smaller, it will not only affect the uniformity of the mixing, but may also cause the meat slices to absorb the spices unevenly, thus affecting the final taste and quality.

[0013] A mixing and stirring method for processing jerky, comprising:

[0014] S1. Open the sealed door hinged on one side of the mixing drum, and then place the sliced ​​meat and spices and other ingredients into the mixing drum;

[0015] S2, start the servo motor to drive the mixing drum and the mixing frame to rotate in the same direction, so that the meat slices and spices are evenly mixed. During the mixing process, the meat slices are beaten and cooled by the provided protrusions in cooperation with the refrigeration semiconductor to maintain the elasticity of the mixed meat slices;

[0016] S3, turn off the servo motor to stop the mixing drum and the mixing frame from rotating, open the sealing door, take out the mixed meat slices from the mixing drum and place them in a receiving barrel for marinating.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. During the rotation of the mixing drum and the mixing frame, the meat slices are affected by the centrifugal force and can move to the inner wall of the mixing drum, and are pushed by the protrusions to move along the circumferential direction of the mixing drum. During this process, the meat slices move from the bottom to the top, and when they reach the top, they fall due to gravity, achieving a beating effect. This can not only be used to separate the meat slices, but also help improve the taste and texture of the meat slices. At the same time, during the contact between the meat slices and the protrusions, the refrigeration semiconductors connected to the protrusions can cool the meat slices, ensure the overall temperature in the mixing drum, and avoid the situation where the meat slices stick together due to excessive temperature. This setting can avoid the situation where the meat slices stick together and affect the mixing uniformity;

[0019] 2. The air guide plate is set up so that the air guide plate is affected by the centrifugal force of the mixing drum, and due to the magnetic force of the first magnetic frame and the second magnetic frame, the air guide plate is subjected to attraction and repulsion. The combined effect of these forces will cause the air guide plate to move back and forth, and when the protrusion slides left and right periodically, the drainage holes opened on the air guide plate can accelerate the flow of air in the protrusion, dissipate heat at the heat dissipation end of the refrigeration semiconductor, and ensure the normal operation of the refrigeration semiconductor. This setting is convenient;

[0020] 3. Start the drive motor to drive the installed gear and then install the transmission rack meshing on the gear to drive the contact plate to move away from the connecting gear ring or close to the connecting gear ring, thereby expanding or reducing the driving radius of the second synchronous wheel, changing the transmission ratio of the first synchronous wheel to the second synchronous wheel, and changing the speed of the mixing drum from slow to fast. The slower initial speed helps to reduce the impact force on the meat slices in the initial stage of mixing, which can prevent the meat slices from being torn or damaged due to excessive mixing, thereby helping to maintain the integrity and elasticity of the meat.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-8 The present invention provides a technical solution: comprising a frame 1, a mixing drum 2 rotatably connected to the frame 1, a mixing frame 3 rotatably connected to the mixing drum 2, and a servo motor 7 connected to one side of the frame 1 for driving the mixing frame 3 to rotate, two symmetrical sealing doors 10 are hinged on the mixing drum 2 for convenient feeding and discharging, a mixing auxiliary component 400 for preventing meat slices from sticking together during mixing, a transmission component 800 for driving the mixing drum 2 and the mixing frame 3 to rotate synchronously, and an adjustment component 900 for controlling the speed of the mixing drum 2 from low to high;

[0032] The present invention is mainly used for the manufacture of butcher shops. During use, pork hind leg meat can be first sliced, and then the sliced ​​meat slices, fish sauce, soy sauce and spices are put into a mixing drum 2 for stirring. After the stirring is completed, the raw materials are taken out, and seasonings such as black pepper, white sesame and salt are added to marinate for a period of time, and then the meat slices are dried and air-dried again. However, the present invention only needs to put the sliced ​​meat slices, fish sauce, soy sauce and spices into the mixing drum 2 for stirring. At the same time, as a necessity, of course, the present invention needs to be used in conjunction with loading and unloading equipment, but since it is irrelevant to the technical problem to be solved by the present invention, it is not drawn;

[0033] By using the components in the stirring auxiliary component 400 in coordination, the meat slices that are stuck together can be beaten during the stirring process to separate them, thereby improving the stirring effect. At the same time, the temperature in the stirring drum 2 can be maintained during the stirring process to avoid the situation where the meat slices are stuck together due to high temperature. The transmission component 800 is convenient for using the stirring drum 2 and the stirring frame 3 to stir synchronously to improve the stirring efficiency while stirring the meat slices in one direction, thereby reducing the distortion and excessive stretching of lean meat during the stirring process, which helps to maintain its original elasticity and taste. The adjustment component 900 is convenient for controlling the rotation speed of the stirring drum 2. At the beginning of stirring, the meat slices may be relatively loose and require a slower rotation speed for mixing. As time goes by, the material gradually becomes compact and uniform. At this time, increasing the rotation speed can better complete the stirring task, so that the rotation speed of the stirring drum 2 is first slow and then fast.

[0034] Among them, please refer to Figure 4 and Figure 5 , comprising a frame 1, a mixing drum 2 rotatably connected to the frame 1, a mixing frame 3 rotatably connected to the mixing drum 2, and a servo motor 7 connected to one side of the frame 1 for driving the mixing frame 3 to rotate, a mixing auxiliary component 400 is provided in the mixing drum 2, and the mixing auxiliary component 400 includes a plurality of protrusions 401 connected to the mixing drum 2, and the plurality of protrusions 401 are distributed in a circular array with equal spacing around the central axis of the mixing drum 2; a cooling semiconductor 402 for conducting heat is connected to the protrusion 401, and the cooling semiconductor 402 is connected to the cooling semiconductor 402. The cooling end of the semiconductor 402 is in conflict with the inner bottom wall of the protrusion 401, and an air guide plate 403 is slidably connected inside the protrusion 401. A plurality of guide holes are provided on the air guide plate 403. As the air guide plate 403 slides, external air is guided into the protrusion 401; a first magnetic frame 404 and a second magnetic frame 405 are respectively connected to the protrusion 401, and the air guide plate 403 is located between the first magnetic frame 404 and the second magnetic frame 405. The magnetic poles of the first magnetic frame 404 and the second magnetic frame 405 are opposite.

[0035] During specific implementation, during the rotation of the mixing drum 2 and the mixing frame 3, the meat slices are affected by the centrifugal force and can move to the inner wall of the mixing drum 2, and are pushed by the protrusion 401 to move along the circumferential direction of the mixing drum 2. During this process, the meat slices move from the bottom to the top, and when they reach the top, they fall due to gravity, thereby achieving a beating effect. This can not only be used to separate the meat slices, but also help to improve the taste and texture of the meat slices. At the same time, during the contact between the meat slices and the protrusion 401, the refrigeration semiconductor 402 connected to the protrusion 401 can cool the meat slices to ensure the overall temperature in the mixing drum 2 and avoid the situation where the meat slices stick together due to excessive temperature. During the heat conduction process of the refrigeration semiconductor 402, the air guide plate 403 arranged in the protrusion 401 is affected by the centrifugal force of the rotation of the mixing drum 2, and due to the magnetic force of the first magnetic frame 404 and the second magnetic frame 405, the air guide plate 403 is subjected to attraction and repulsion forces. The combined effect of these forces will cause the air guide plate 403 to move back and forth, and when the bump 401 periodically slides left and right, the guide holes on the air guide plate 403 can accelerate the flow of air in the bump 401, dissipate heat at the heat dissipation end of the cooling semiconductor 402, and ensure the normal operation of the cooling semiconductor 402;

[0036] It should be noted that in this process, the air guide plate 403 is also a magnetic plate;

[0037] Please continue to refer to Figure 4 In order to increase the sliding range of the air guide plate 403, a connecting block 6 is connected inside the protrusion 401, and multiple compression springs 5 ​​are connected to both sides of the air guide plate 403. The multiple compression springs 5 ​​are evenly distributed in a linear array along the length direction of the air guide plate 403; the set connecting block 6 facilitates the installation of the compression spring 5, and the set compression spring 5 facilitates increasing the swing range of the air guide plate 403, thereby improving its air exchange efficiency.

[0038] When you need to drive the mixing drum 2 and the mixing frame 3 to rotate synchronously, please continue to refer to Figure 2, it is necessary to further disclose the structure inside the transmission assembly 800, which also includes a transmission assembly 800, wherein the transmission assembly 800 includes a first synchronous wheel 801 and a second synchronous wheel 802 which are rotatably connected in the frame 1, a first synchronous belt 803 is transmission-connected between the first synchronous wheel 801 and the second synchronous wheel 802, a third synchronous wheel 804 which rotates synchronously with the second synchronous wheel 802 is connected to one side of the second synchronous wheel 802, a fourth synchronous wheel 805 is rotationally provided on one side of the third synchronous wheel 804, a second synchronous belt 806 is transmission-connected between the third synchronous wheel 804 and the fourth synchronous wheel 805, a connecting shaft 807 is connected to the second synchronous belt 806, a driving gear 808 is connected to the connecting shaft 807, a driven gear ring 809 is meshedly connected to the driving gear 808, the driven gear ring 809 is connected to the mixing drum 2, and the first synchronous wheel 801 is connected to the driving shaft of the servo motor 7;

[0039] In specific implementation, the servo motor 7 can drive the first synchronous wheel 801 to rotate, which is then driven by the first synchronous belt 803 to rotate the second synchronous wheel 802. Then, the third synchronous wheel 804 that rotates synchronously on one side of the second synchronous wheel 802 can be driven by the second synchronous belt 806 to drive the fourth synchronous wheel 805 to rotate. During the rotation of the fourth synchronous wheel 805, the driving gear 808 rotates synchronously and drives the driven gear ring 809 to rotate. During the rotation of the driven gear ring 809, the mixing drum 2 can rotate synchronously.

[0040] Please continue to refer to Figure 2 , the frame 1 is connected with a connecting frame 11, the driving gear 808 is rotatably connected to the connecting frame 11, the root diameter of the driving gear 808 is smaller than the root diameter of the driven gear ring 809, firstly, since the root diameters of the driving gear 808 and the driven gear ring 809 are different, the transmission ratios are different, and at this time, the purpose of the mixing drum 2 rotating at a slower speed and the mixing frame 3 rotating at a faster speed can be achieved. In this process, the mixing frame 3 rotates at a higher speed to provide a stronger stirring force, while the mixing drum 2 rotates at a lower speed to assist in the process of beating the meat slices. In this way, the meat slices can be fully mixed during the stirring process;

[0041] It should be noted that, in order to facilitate the rotation of the mixing drum 2 and support the mixing drum 2, a plurality of transmission pulleys 12 are connected to the frame 1, and the plurality of transmission pulleys 12 are distributed in a circular array in the frame 1, and the top of the transmission pulley 12 is in conflict with the mixing drum 2. The plurality of transmission pulleys 12 are divided into two groups and are symmetrically arranged in the frame 1; the arranged transmission pulleys 12 are convenient for supporting the mixing drum 2 and at the same time convenient for assisting the rotation of the mixing drum 2.

[0042] Please continue to refer to Figure 7 and Figure 8In order to facilitate the adjustment of the rotation speed of the mixing drum 2 so as to change the rotation speed of the mixing drum 2 from slow to fast, an adjustment component 900 is also included in the second synchronous wheel 802. The adjustment component 900 includes a connecting gear ring 901 rotatably connected to the second synchronous wheel 802. The connecting gear ring 901 is meshedly connected with a plurality of mounting gears 902. The plurality of mounting gears 902 are distributed in a circular array in the second synchronous wheel 802. A transmission rack 903 is meshedly connected to one side of the mounting gear 902. One end of the transmission rack 903 extends to the outside of the second synchronous wheel 802 and is connected to a contact plate 904. A driving motor 905 for driving one of the mounting gears 902 to rotate is connected to the second synchronous wheel 802.

[0043] In specific implementation, the driving motor 905 is started to drive one of the mounting gears 902 to rotate. During the rotation of the mounting gear 902, the connecting gear ring 901 is driven to rotate. Then, the connecting gear ring 901 drives the remaining mounting gears 902 to rotate synchronously. Then, the transmission rack 903 meshingly connected on the mounting gear 902 can drive the contact plate 904 to move away from the connecting gear ring 901 or close to the connecting gear ring 901, thereby expanding the driving radius of the second synchronous wheel 802, changing the transmission ratio of the first synchronous wheel 801 and the second synchronous wheel 802, and making the speed of the mixing drum 2 change from slow to fast. The slower initial speed helps to reduce the impact force on the meat slices in the initial stage of mixing, so as to avoid the meat slices being torn or damaged due to excessive mixing, thereby helping to maintain the integrity and elasticity of the meat.

[0044] Furthermore, the contact plate 904 is designed to be arc-shaped, and the outside of the contact plate 904 is integrally formed with anti-slip patterns. The second synchronous wheel 802 is provided with a plurality of connection ports that are compatible with the transmission rack 903. The plurality of connection ports are distributed in a circular array with equal intervals. The arc design facilitates a better transition of the second synchronous belt 806 during transmission. The second synchronous belt 806 can be made of elastic material for better transmission.

[0045] A mixing and stirring method for processing jerky, comprising:

[0046] S1, open the sealed door 10 hinged on one side of the mixing drum 2, and then place the cut meat slices and spices and other ingredients in the mixing drum 2;

[0047] S2, start the servo motor 7 to drive the mixing drum 2 and the mixing frame 3 to rotate in the same direction, so that the meat slices and spices are evenly mixed. During the mixing process, the provided protrusions 401 and the refrigeration semiconductor 402 are used in conjunction to beat and cool the meat slices, so as to maintain the elasticity of the mixed meat slices;

[0048] S3, turn off the servo motor 7 to stop the mixing drum 2 and the mixing frame 3 from rotating, open the sealing door 10, take out the mixed meat slices from the mixing drum 2 and place them in a material receiving barrel for marinating.

[0049] Working principle: When using:

[0050] During the rotation of the mixing drum 2 and the mixing frame 3, the meat slices are affected by the centrifugal force and can move to the inner wall of the mixing drum 2, and are pushed by the protrusion 401 to move along the circumferential direction of the mixing drum 2. During this process, the meat slices move from the bottom to the top, and when they reach the top, they fall due to gravity, achieving a beating effect. This can not only be used to separate the meat slices, but also help to improve the taste and texture of the meat slices. At the same time, during the contact between the meat slices and the protrusion 401, the refrigeration semiconductor 402 connected to the protrusion 401 can cool the meat slices to ensure the overall temperature in the mixing drum 2 and avoid the situation where the meat slices stick together due to excessive temperature. During the heat conduction process of the refrigeration semiconductor 402, the air guide plate 403 arranged in the protrusion 401 is affected by the centrifugal force of the rotation of the mixing drum 2, and due to the magnetic force of the first magnetic frame 404 and the second magnetic frame 405, the air guide plate 403 is subjected to attraction and repulsion forces. The combined effect of these forces will cause the air guide plate 403 to move back and forth, and when the bump 401 periodically slides left and right, the guide holes on the air guide plate 403 can accelerate the flow of air in the bump 401, dissipate heat at the heat dissipation end of the cooling semiconductor 402, and ensure the normal operation of the cooling semiconductor 402;

[0051] The servo motor 7 can drive the first synchronous wheel 801 to rotate, which is then driven by the first synchronous belt 803 to rotate the second synchronous wheel 802. Then, the third synchronous wheel 804 that rotates synchronously on one side of the second synchronous wheel 802 can be driven by the second synchronous belt 806 to drive the fourth synchronous wheel 805 to rotate. During the rotation of the fourth synchronous wheel 805, the driving gear 808 rotates synchronously and drives the driven gear ring 809 to rotate. During the rotation of the driven gear ring 809, the mixing drum 2 can rotate synchronously.

[0052] By starting the driving motor 905 to drive one of the mounting gears 902 to rotate, the mounting gear 902 drives the connecting gear ring 901 to rotate during the rotation, and then the connecting gear ring 901 drives the remaining mounting gears 902 to rotate synchronously, and then the transmission rack 903 meshingly connected on the mounting gear 902 can drive the contact plate 904 to move away from the connecting gear ring 901 or close to the connecting gear ring 901, thereby expanding the driving radius of the second synchronous wheel 802, changing the transmission ratio of the first synchronous wheel 801 and the second synchronous wheel 802, and changing the speed of the mixing drum 2 from slow to fast. The slower initial speed helps to reduce the impact force on the meat slices in the initial stage of mixing, thereby preventing the meat slices from being torn or damaged due to excessive mixing, thereby helping to maintain the integrity and elasticity of the meat.
