Description

Technical Field

[0001] The present invention relates to the technical field of meat powder preparation, and particularly to a device and method for preparing meat powder based on the Maillard reaction. Background Art

[0002] A device for preparing meat powder based on the Maillard reaction is an industrial production equipment that promotes the Maillard reaction to enhance the flavor and quality of meat powder by optimizing the heating and stirring mechanisms. The Maillard reaction is a non-enzymatic browning reaction that occurs between reducing sugars (such as glucose) and amino groups in proteins at high temperatures, generating melanoidins, reductones, and heterocyclic compounds containing N / S / O. These products are the main sources of the characteristic flavors of meat products (such as roasted meat aroma and burnt aroma).

[0003] After retrieval, a Chinese patent with the publication number CN116268475B discloses a device and method for preparing meat powder based on the Maillard reaction. High-temperature steam is output into the diversion ring by a steam generator, and a part of the high-temperature steam flows into the hollow heating column and eight heating tubes, so that a high-temperature environment is formed inside the outer shell to steam the meat powder at a high temperature. A part of the high-temperature steam flows out from several air holes of the diversion ring and fills the space between the diversion ring and the heating partition, causing the heating partition to heat up and heat the meat powder. The steam will flow back into the steam generator to form a reciprocating cycle of high-temperature steam, keeping the steam at a high temperature all the time for continuous heating of the meat powder, and the Maillard reaction occurs to produce fragrance. The meat powder is mildly heated by a microwave heater, which can make the meat powder form a roasted fragrance and make the flavor of the meat powder better. However, when this solution is actually used, there are still the following deficiencies:

[0004] In the process of meat powder preparation, the key step of the above device is to heat and stir the raw materials with high-temperature steam to promote the necessary physical and chemical changes of these components to form a uniform and delicate meat powder. However, since the raw materials used often contain a certain amount of moisture, during the high-temperature treatment process, these moisture may increase the adhesion between raw material particles, resulting in caking. This caking will not only reduce production efficiency but also lead to uneven texture of the final product, affecting the quality of the meat powder and its subsequent processing performance.

[0005] Therefore, the present application provides a device and method for preparing meat powder based on the Maillard reaction. Summary of the Invention

[0018] A method for preparing meat powder based on the Maillard reaction, according to the above-mentioned meat powder preparation device based on the Maillard reaction, includes the following steps:

[0019] Step 1: The staff adds raw materials into the preparation kettle through the feeding port. Initially, the unfolding plate is in an unfolded state outside the blanking ring body. The jacket is filled with high-temperature steam to heat the inside of the kettle. At the same time, the driving motor is started to drive the stirring sleeve and the unfolding plate to rotate, mixing and stirring the raw materials and triggering the Maillard reaction.

[0020] Step 2: The connecting cylinder at the end of the stirring sleeve rotates by meshing with gears, and the inclined stirring plate further stirs the raw materials.

[0021] Step 3: After the meat powder is prepared, the electric push rod is shortened to make the unfolding plate close into a frustum shape and enter the blanking ring body, leaving a meat powder passage.

[0023] The beneficial effects of the present invention:

[0024] 1. For the meat powder preparation device and method based on the Maillard reaction, by setting the stirring sleeve and the connecting cylinder, through the synergistic effect of heating with high-temperature steam in the jacket and the rotation of the stirring sleeve and the unfolding plate, the raw materials are quickly and evenly mixed, and at the same time, the Maillard reaction occurs, significantly improving the flavor of the meat powder. The double stirring mechanism (overall rotation of the stirring sleeve + self-rotation of the connecting cylinder) further enhances the mixing efficiency.

[0025] 2. The meat powder preparation device and method based on the Maillard reaction can switch the expansion plate from the expanded state to the closed state by setting the electric push rod and the electromagnet, which not only meets the stirring requirement in the preparation stage, but also realizes the anti-caking function in the discharging stage. At the same time, the electromagnet adjusts the angle of the stirring plate magnetically, synchronously completing the conversion between the stirring mode and the cleaning mode, reflecting the multi-functional integration of the equipment.

[0026] 3. The meat powder preparation device and method based on the Maillard reaction can automatically brush the inner wall of the kettle with the cleaning brush on the side as the stirring sleeve rotates after the stirring plate is driven vertically by magnetic force by setting the stirring plate and the cleaning brush plate, effectively preventing the pollution caused by the adhesion of meat powder, reducing the need for manual cleaning, and improving the production continuity and hygiene standards.

[0027] 4.

[0042] As Figures 1 to 9 shown, a meat powder preparation device based on the Maillard reaction includes a preparation kettle 1 and a feeding port 2 provided on the top surface of the preparation kettle 1. A discharge pipe 3 is provided at the bottom surface of the preparation kettle 1. A driving motor 4 is fixedly installed on the top surface of the preparation kettle 1. A conversion assembly is provided inside the preparation kettle 1. A plurality of uniformly distributed stirring sleeves 6 are fixedly installed on the conversion assembly. Cleaning components are provided at one ends of the plurality of stirring sleeves 6 away from the conversion assembly. A jacket 9 is provided on the inner side of the outer wall of the preparation kettle 1;

[0043] The conversion component includes a driving cylinder 51 rotatably installed on the inner top surface of the preparation kettle 1, and the top end of the driving cylinder 51 is fixedly connected to the output end of the driving motor 4. An electric push rod 55 is fixedly installed on the inner wall of the bottom opening of the driving cylinder 51. The end of the stirring sleeve 6 is fixedly connected to the outer wall of the driving cylinder 51;

[0044] The conversion component further includes a plurality of mounting openings 52 formed in the bottom end of the driving cylinder 51 and distributed in an annular array. A rotating plate 53 is rotatably installed on the inner wall of the mounting opening 52 through a rotating shaft. One end of the rotating plate 53 located outside the driving cylinder 51 is fixedly installed with an unfolding plate 54. The combined state of the plurality of unfolding plates 54 is in the shape of a frustum of a cone. A plurality of through holes 56 corresponding to the mounting openings 52 and distributed in an annular array are formed in the telescopic end of the electric push rod 55. One end of the rotating plate 53 located inside the driving cylinder 51 is fixedly installed with a connecting telescopic rod 57, and the telescopic end of the connecting telescopic rod 57 is rotatably connected to the inner wall of the through hole 56. A blanking ring body 58 corresponding to the plurality of unfolding plates 54 is fixedly installed on the inner bottom surface of the preparation kettle 1. The cross-sectional shape of the blanking ring body 58 is triangular. Stirring plates 59 are fixedly installed on the inner walls of the plurality of unfolding plates 54;

[0045] Workers can add the raw materials for meat powder preparation into the preparation kettle 1 through the feeding port 2. In the initial state, the plurality of unfolding plates 54 are in the unfolded state, and their unfolded state is as Figure 3 shown. The plurality of unfolding plates 54 can be located outside the blanking ring body 58. After the raw materials are added, circulating high-temperature steam can be filled into the jacket 9 to heat the inside of the preparation kettle 1 through the jacket 9. And during the heating process, the driving motor 4 is started synchronously to drive the driving cylinder 51 to rotate. When the driving cylinder 51 rotates, it can drive the stirring sleeve 6 and the plurality of unfolding plates 54 to rotate. When the stirring sleeve 6, the unfolding plates 54 and the stirring plates 59 rotate, they can stir the raw materials in the preparation kettle 1, so that the raw materials are fully mixed. And under the action of the heating of the jacket 9, the Maillard reaction can occur between the raw materials to increase the taste of the meat powder. When the meat powder preparation is completed, at this time, the worker can start the electric push rod 55 to shorten. When the electric push rod 55 shortens, it can drive the rotating plate 53 to rotate in the mounting opening 52 through the connecting telescopic rod 57, so that the plurality of unfolding plates 54 can rotate to the closed state. After the unfolding plates 54 are closed, they can be combined into the shape of a frustum of a cone and can be located in the blanking ring body 58. And there is a certain distance between the outer wall of the unfolding plate 54 and the inner wall of the blanking ring body 58 for the meat powder to pass through. When the closed unfolding plates 54 rotate in the blanking ring body 58, when the meat powder passes through the space between the blanking ring body 58 and the unfolding plates 54, under the action of the rotation of the unfolding plates 54, the agglomerated meat powder can be ground and broken, effectively avoiding the appearance of agglomeration. And the meat powder passing through the space between the unfolding plates 54 and the blanking ring body 58 can be discharged through the discharge pipe 3.

[0046] AsFigure 7 , Figure 8 , Figure 9 As shown in Figure 9 , the cleaning component includes a connecting cylinder 71 movably installed at the end of the stirring sleeve 6. The connecting cylinder 71 is made of a metal material. Two stirring plates 74 are symmetrically arranged on the outer wall of the connecting cylinder 71;

[0047] The cleaning component further includes two through openings 72 symmetrically opened on the outer wall of the connecting cylinder 71. A shaft rod 73 is rotatably installed on the inner wall of the through opening 72, and the stirring plate 74 is fixedly sleeved on the shaft rod 73. A torsion spring 75 is sleeved at the end of the shaft rod 73, and both ends of the torsion spring 75 are fixedly connected to the through opening 72 and the shaft rod 73 respectively. A cleaning brush plate 77 is arranged on the side of the stirring plate 74. A connecting rod 78 is fixedly installed at the end of the connecting cylinder 71, and a transmission gear 79 is fixedly installed at the end of the connecting rod 78. A fixed ring 710 corresponding to the transmission gear 79 is fixedly installed on the inner wall of the preparation kettle 1. A plurality of fixed teeth 711 distributed in an annular array are fixedly installed on the bottom surface of the fixed ring 710, and the transmission gear 79 meshes with the fixed teeth 711;

[0048] When the stirring sleeve 6 rotates with the driving cylinder 51, the two stirring plates 74 on the connecting cylinder 71 at its end are in the Figure 7 shown state. The two stirring plates 74 are inclined, and at this time, the transmission gear 79 is in meshing with the fixed teeth 711 on the bottom surface of the fixed ring 710. Therefore, when the stirring sleeve 6 drives the connecting cylinder 71 to rotate with the driving cylinder 51, the connecting cylinder 71 can rotate itself under the action of the meshing of the transmission gear 79 and the fixed teeth 711. When the connecting cylinder 71 rotates itself, the two stirring plates 74 on its outer wall can rotate to fully stir the raw materials in the preparation kettle 1 so that the Maillard reaction occurs.

[0049] As Figure 7 , Figure 8 shown, an adjusting structure for adjusting the angle of the stirring plate 74 is arranged between the stirring sleeve 6 and the connecting cylinder 71. The adjusting structure includes a connecting magnetic sheet 81 fixedly installed at one end of the stirring plate 74 located inside the connecting cylinder 71. An electromagnet 82 is fixedly installed on the inner wall of the stirring sleeve 6. A sliding ring 84 is slidably installed on the inner wall of the stirring sleeve 6, and the connecting cylinder 71 is rotatably connected to the sliding ring 84. A plurality of positioning plates 83 distributed in an annular array are fixedly installed on the inner wall of the stirring sleeve 6. A support spring 85 is fixedly installed between the positioning plate 83 and the sliding ring 84. A limiting rod 76 corresponding to the connecting magnetic sheet 81 is fixedly installed on the inner wall of the connecting cylinder 71;

[0050] When the stirring work is carried out, the electromagnet 82 is in the on state at this time. Under the magnetic force adsorption of the connecting magnetic sheet 81, the stirring plate 74 is in an inclined state. While shortening the electric push rod 55, the magnetic force of the electromagnet 82 can be increased. When the magnetic force of the electromagnet 82 is increased, under the action of a greater magnetic force adsorption, first of all, the connecting magnetic sheet 81 can rotate through the shaft rod 73. And with the coordinated use of the limiting rod 76, the connecting magnetic sheet 81 and the stirring plate 74 can rotate to a state perpendicular to the outer wall of the connecting cylinder 71. At the same time, since the connecting cylinder 71 is made of a metal material, during the stirring state, under the supporting action of the supporting spring 85 and the positioning plate 83, the connecting cylinder 71 will not move in position when being magnetically adsorbed. When the magnetic force is increased, the connecting cylinder 71 can slide into the stirring sleeve 6 in the direction of the inner wall of the stirring sleeve 6 through the sliding ring 84 under the action of magnetic force adsorption. As the connecting cylinder 71 moves, the transmission gear 79 can be separated from the fixed tooth 711. And when the stirring plate 74 rotates to a state perpendicular to the outer wall of the connecting cylinder 71, the cleaning brush plate 77 on its side can be attached to the inner wall of the preparation kettle 1. Subsequently, continue to start the driving motor 4. As the driving cylinder 51 rotates, the cleaning brush plate 77 on the side of the stirring plate 74 can clean the inner wall of the preparation kettle 1 to avoid the adhesion of meat powder.

[0051] A method for preparing meat powder based on the Maillard reaction, according to the above-mentioned meat powder preparation device based on the Maillard reaction, includes the following steps:

[0052] Step 1: The staff adds raw materials into the preparation kettle 1 through the feeding port 2. Initially, the unfolding plate 54 is in the unfolded state outside the blanking ring body 58. The jacket 9 is filled with high-temperature steam to heat the inside of the kettle. At the same time, start the driving motor 4 to drive the stirring sleeve 6 and the unfolding plate 54 to rotate, mix and stir the raw materials and trigger the Maillard reaction.

[0053] Step 2: The connecting cylinder 71 at the end of the stirring sleeve 6 realizes self-rotation through gear meshing, and the inclined stirring plate 74 further stirs the raw materials.

[0054] Step 3: After the meat powder is prepared, shorten the electric push rod 55 to make the unfolding plate 54 close into a frustum of a cone shape and enter the blanking ring body 58, leaving a meat powder passage. At the same time, the magnetic force of the electromagnet 82 is enhanced, adsorbing the stirring plate 74 to rotate to be perpendicular to the connecting cylinder 71. At the same time, the connecting cylinder 71 slides towards the inner wall of the stirring sleeve 6 to disengage from the gear meshing, and the cleaning brush plate 77 is attached to the inner wall of the kettle.

[0055] Step 4: The cleaning brush plate 77 on the side of the vertical stirring plate 74 rotates with the driving motor 4 to clean the inner wall of the kettle. The closed unfolding plate 54 rotates and grinds the agglomerated meat powder. Finally, the meat powder is discharged through the discharge pipe 3.

[0056] When the technical solution provided by the present invention is used, first, the staff can add the raw materials for preparing meat powder into the preparation kettle 1 through the feeding port 2. In the initial state, several unfolding plates 54 are in the unfolded state, and their unfolded state is as shown in Figure 3 shown. Several unfolding plates 54 can be located outside the blanking ring body 58. After the raw materials are added, circulating high-temperature steam can be filled into the jacket 9 to heat the inside of the preparation kettle 1 through the jacket 9. And during the heating process, the driving motor 4 is turned on synchronously to drive the driving cylinder 51 to rotate. When the driving cylinder 51 rotates, it can drive the stirring sleeve 6 and several unfolding plates 54 to rotate. When the stirring sleeve 6, the unfolding plates 54, and the material distributing plates 59 rotate, they can stir the raw materials in the preparation kettle 1 to make the raw materials fully mixed. And under the action of the heating of the jacket 9, the Maillard reaction can occur between the raw materials to increase the taste of the meat powder;

[0057] When the stirring sleeve 6 rotates with the driving cylinder 51, the two stirring plates 74 on the connecting cylinder 71 at its end are in the state shown in Figure 7 shown. The two stirring plates 74 are inclined, and at this time, the transmission gear 79 is engaged with the fixed teeth 711 on the bottom surface of the fixed ring 710. Therefore, when the stirring sleeve 6 drives the connecting cylinder 71 to rotate with the rotation of the driving cylinder 51, the connecting cylinder 71 can rotate self-driven under the engagement of the transmission gear 79 and the fixed teeth 711. When the connecting cylinder 71 rotates self-driven, the two stirring plates 74 on its outer wall can rotate to fully stir the raw materials in the preparation kettle 1 to facilitate the Maillard reaction. After the meat powder is prepared, at this time, the staff can turn on the electric push rod 55 to shorten it. When the electric push rod 55 shortens, it can drive the rotating plate 53 to rotate in the installation opening 52 through the connecting telescopic rod 57, so that several unfolding plates 54 can rotate to the closed state. After the unfolding plates 54 are closed, they can be combined into a frustum of a cone shape and can be located in the blanking ring body 58. And there is a certain distance between the outer wall of the unfolding plate 54 and the inner wall of the blanking ring body 58 to facilitate the passage of the meat powder;

[0058] When the stirring work is carried out, the electromagnet 82 is in the on state at this time. Under the action of the magnetic force adsorption connecting the magnetic sheet 81, the stirring plate 74 is in an inclined state. While shortening the electric push rod 55, the magnetic force of the electromagnet 82 can be increased. When the magnetic force of the electromagnet 82 is increased, under the action of a greater magnetic force adsorption, first, the connecting magnetic sheet 81 can rotate through the shaft rod 73, and with the coordinated use of the limiting rod 76, the connecting magnetic sheet 81 and the stirring plate 74 can rotate to a state perpendicular to the outer wall of the connecting cylinder 71. At the same time, since the connecting cylinder 71 is made of a metal material, when being stirred, under the supporting action of the supporting spring 85 and the positioning plate 83, the connecting cylinder 71 will not move in position when being subjected to magnetic force adsorption. When the magnetic force is increased, the connecting cylinder 71 can slide into the stirring sleeve 6 in the direction of the inner wall of the stirring sleeve 6 through the sliding ring 84 under the action of magnetic force adsorption. As the connecting cylinder 71 moves, the transmission gear 79 can be separated from the fixed tooth 711, and when the stirring plate 74 rotates to a state perpendicular to the outer wall of the connecting cylinder 71, the cleaning brush plate 77 on its side can be attached to the inner wall of the preparation kettle 1;

[0059] Subsequently, continue to start the driving motor 4. As the driving cylinder 51 rotates, the cleaning brush plate 77 on the side of the stirring plate 74 can clean the inner wall of the preparation kettle 1 to avoid the adhesion of meat powder. When the unfolded plate 54 in the closed state rotates in the blanking ring body 58, when the meat powder passes through the gap between the blanking ring body 58 and the unfolded plate 54, the agglomerated meat powder can be ground and broken under the action of the rotation of the unfolded plate 54, effectively avoiding the occurrence of agglomeration. The meat powder passing through the gap between the unfolded plate 54 and the blanking ring body 58 can be discharged through the discharge pipe 3, and the staff can directly collect it.
