[0034] The technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0035] Embodiment 1

[0036] See Figures 1 - 7 , the present invention provides an energy-saving refrigeration device for freeze-drying camellia nitidissima, including:

[0037] A stable base 1, on which a freeze-drying cylinder 2 and a refrigerator 3 are fixedly arranged, and a refrigeration mechanism is arranged on the freeze-drying cylinder 2 and the refrigerator 3;

[0038] The refrigeration mechanism includes a rotating shaft 4, a feeding hopper 5, a connecting piece 6, a sleeve 7, a cold air duct 8, a generator 9, a power generation shaft 10 and a paddle 11;

[0039] The rotating shaft 4 is rotatably installed on the freeze-drying cylinder 2, the feeding hopper 5 is fixedly installed on the freeze-drying cylinder 2, the connecting piece 6 is fixedly installed between the feeding hopper 5 and the sleeve 7, the rotating shaft 4 is in sealed contact with the sleeve 7, the cold air pipe 8 is fixedly installed between the refrigerator 3 and the sleeve 7, the generator 9 is fixedly installed on the top of the sleeve 7, the output end of the generator 9 is fixedly connected to the power generation shaft 10, the bottom of the power generation shaft 10 is fixedly connected to the rotating shaft 4, the paddle 11 is fixedly installed on the outside of the power generation shaft 10, and the port of the cold air pipe 8 faces the paddle 11.

[0040] Specifically, a discharge pipe is fixedly connected to the bottom of the freeze-drying cylinder 2, a discharge valve is installed on the discharge pipe, a first support member is fixedly connected to the bottom of the freeze-drying cylinder 2, and the bottom of the first support member is fixedly connected to the stable base 1. A second support member is fixedly connected to the bottom of the refrigerator 3, and the bottom of the second support member is fixedly connected to the stable base 1. It should be noted that in this way, the freeze-drying cylinder 2 and the refrigerator 3 can be stably supported. The arrangement of the discharge pipe and the discharge valve facilitates the discharge process, and excessive cold air leakage will not occur during discharge, which is relatively energy-saving and environmentally friendly.

[0041] Through the above structure, the cold air conveyed by the refrigerator 3 through the cold air pipe 8 impacts the paddle 11, causing the paddle 11 to drive the power generation shaft 10 to rotate, and then driving the generator 9 to work and generate electricity, converting the mechanical energy of the cold air flow into electrical energy to achieve energy recovery. At the same time, the power generation shaft 10 drives the rotating shaft 4 to rotate, providing power for subsequent pre-cooling, stirring, and auxiliary freeze-drying operations, reducing the equipment's dependence on external electrical energy and reducing the overall energy consumption;

[0042] The rotating shaft 4 is in sealed contact with the sleeve 7, and the feeding hopper 5 is fixedly connected to the sleeve 7 through the connecting piece 6. This structure makes the internal space of the sleeve 7 relatively sealed. During the operation of the equipment, a large amount of cold air can be effectively prevented from leaking to the outside, improving the utilization efficiency of the cold air and reducing energy waste.

[0043] Embodiment 2

[0044] See Figure 6 , the present invention provides an energy-saving refrigeration device for freeze-drying camellia nitidissima, which further includes a pre-cooling component. The pre-cooling component includes a barrier mesh plate 13, a sphere one 14, a connecting rod 15, a sphere two 16, a vertical plate 17, a spring one 18, a stirring member 19, a bevel gear one 20, and a bevel gear two 21. The barrier mesh plate 13 is slidably installed on the feeding hopper 5, the sphere one 14 is fixedly installed on the side of the barrier mesh plate 13, one end of the connecting rod 15 is fixedly connected to the rotating shaft 4, the other end of the connecting rod 15 is fixedly connected to the sphere two 16, the vertical plate 17 is fixedly installed on the top of the barrier mesh plate 13, the spring one 18 is fixedly installed between the feeding hopper 5 and the vertical plate 17, the stirring member 19 is rotatably installed on the feeding hopper 5, the bevel gear one 20 is fixedly connected to one end of the stirring member 19, the bevel gear two 21 is fixedly sleeved on the outside of the rotating shaft 4, and the bevel gear one 20 meshes with the bevel gear two 21.

[0045] With the above structure, under the intermittent collision of the blocking net plate 13 between the second sphere 16 and the first sphere 14, the blocking net plate 13 makes a reciprocating horizontal slide in the feeding hopper 5. The mesh holes at its top enable part of the cold air in the sleeve 7 to pass through, pre-cooling the camellia flower material in the feeding hopper 5. This reciprocating slide increases the contact opportunity between the cold air and the material, reduces the initial temperature of the material before entering the freeze-drying cylinder 2, helps improve the subsequent freeze-drying efficiency, and reduces the energy consumption of the refrigerating machine 3 during the freeze-drying process;

[0046] When the rotating shaft 4 rotates, it drives the second bevel gear 21 fixedly sleeved on the outside of it to rotate. The second bevel gear 21 meshes with the first bevel gear 20, so that the stirring member 19 fixedly connected to the first bevel gear 20 rotates in the feeding hopper 5. The rotation of the stirring member 19 stirs the camellia flower material, prevents the material from accumulating in the feeding hopper 5, enables the material to be evenly heated and cooled during the pre-cooling process, further improves the pre-cooling effect, ensures the temperature consistency of the material when entering the freeze-drying cylinder 2, and is conducive to the smooth progress of the subsequent freeze-drying process;

[0047] The reciprocating slide of the blocking net plate 13 not only helps with pre-cooling and stirring, but also plays a certain role in controlling the transportation of the camellia flower material. When the blocking net plate 13 slides, the speed and quantity of the material entering the freeze-drying cylinder 2 can be appropriately adjusted, avoiding excessive material entering at one time and affecting the freeze-drying effect, enabling the material to enter the freeze-drying cylinder 2 orderly, and improving the controllability of the freeze-drying process;

[0048] The linkage between the components of the pre-cooling assembly is based on the rotation of the rotating shaft 4. Through the transmission of structures such as the connecting rod 15 and the bevel gears 20 and 21, the power of the rotating shaft 4 is cleverly converted into the reciprocating motion of the blocking net plate 13 and the rotation of the stirring member 19, realizing the reasonable utilization of energy, conforming to the design concept of energy-saving refrigeration equipment, and reducing the overall energy consumption of the equipment.

[0049] Specifically, a threaded cover is connected to the top of the feeding hopper 5 by threads. The first sphere 14 and the second sphere 16 have the same specifications. Mesh holes are provided at the top of the blocking net plate 13. It should be noted that this facilitates the passage of cold air.

[0050] Embodiment 3

[0051] See Figure 6 and Figure 7, the present invention provides an energy-saving refrigeration device for freeze-drying Camellia nitidissima, which further includes an auxiliary freeze-drying component. The auxiliary freeze-drying component includes an air inlet hole 12, a stirring rod 22, a sealing piston 23, an air outlet hole 24, an inner plate 25, a cross bar 26, a retaining plate 27 and a second spring 28. The air inlet holes 12 are equidistantly arranged on the outer side of the rotating shaft 4. The rotating shaft 4 is of a hollow structure, and the air inlet holes 12 are communicated with the inside of the rotating shaft 4. The stirring rod 22 is fixedly installed on the outer side of the rotating shaft 4. An air vent hole is provided on the stirring rod 22, and the air vent hole is communicated with the inside of the rotating shaft 4. The sealing piston 23 is slidably and sealingly installed in the stirring rod 22. The air outlet holes 24 are equidistantly arranged on the outer side of the sealing piston 23. The inner plate 25 is fixedly installed in the air vent hole. One end of the cross bar 26 is fixedly connected to the sealing piston 23. The cross bar 26 is slidably installed on the inner plate 25. The other end of the cross bar 26 is fixedly connected to the retaining plate 27. The second spring 28 is fixedly installed between the sealing piston 23 and the inner plate 25.

[0052] Through the above structure, the cold air generated by the refrigerating machine enters the hollow rotating shaft 4 through the air inlet holes 12, and then enters the inside of the stirring rod 22 through the air vent holes on the stirring rod 22. When the rotating shaft 4 rotates, the stirring rod 22 stirs the Camellia nitidissima material, making the material distribution more uniform, increasing the contact area between the material and the cold air, and avoiding the situation of uneven local freeze-drying. At the same time, under the action of centrifugal force and cold air pressure, the sealing piston 23 intermittently opens the air outlet holes 24 to jet air, realizing the pulsed jetting of the Camellia nitidissima material, further improving the heat exchange efficiency between the cold air and the material, thereby effectively improving the freeze-drying efficiency and shortening the freeze-drying time;

[0053] The stirring rod 22 continuously rotates and stirs the Camellia nitidissima material driven by the rotating shaft 4, which can prevent the material from piling up, enabling the material to fully contact the cold air everywhere in the freeze-drying cylinder 2, ensuring that the freeze-drying process proceeds evenly throughout the cylinder, guaranteeing the quality consistency of the freeze-dried Camellia nitidissima, and avoiding the situation of over-drying or under-drying of some materials. The sealing piston 23 is connected to the retaining plate 27 through the cross bar 26. The cross bar 26 slides on the inner plate 25, and the second spring 28 is installed between the sealing piston 23 and the inner plate 25. This structural design enables the sealing piston 23 to stably control the opening and closing of the air outlet holes 24 under the combined action of centrifugal force, cold air pressure and spring elasticity. When the centrifugal force and cold air pressure change, the sealing piston 23 slides correspondingly to open or close the air outlet holes 24, ensuring the regularity and stability of the jetting process, and further guaranteeing the stability and repeatability of the freeze-drying effect;

[0054] This component realizes the reasonable flow and distribution of cold air inside the device. The cold air enters the rotating shaft 4 through the air inlet holes 12, and then acts on the material through the air vent holes and air outlet holes 24 of the stirring rod 22, making full use of the cold air generated by the refrigerating machine 3, reducing the waste of cold air, and improving the energy utilization efficiency, meeting the design requirements of the energy-saving refrigeration device.

[0055] Specifically, the retaining disc 27 is in contact with the inner plate 25. It should be noted that the retaining disc 27 can be limited.

[0056] Working principle:

[0057] S1: The refrigerator 3 conveys cold air into the sleeve 7 through the cold air pipe 8. The cold air jets out from the port of the cold air pipe 8 and directly impacts the paddle 11. Since the paddle 11 is fixedly installed outside the power generation shaft 10, under the impact force of the cold air flow, the paddle 11 drives the power generation shaft 10 to start rotating. The power generation shaft 10 is fixedly connected to the output end of the generator 9. Therefore, the rotation of the power generation shaft 10 drives the generator 9 to work, converting mechanical energy into electrical energy. At the same time, the bottom of the power generation shaft 10 is fixedly connected to the rotating shaft 4, thereby driving the rotating shaft 4 to rotate synchronously. This process not only realizes the recycling of the energy of the cold air flow, provides electrical energy for other electrical components of the equipment such as subsequent stirring components and sensors, reduces the overall energy consumption, but also enables the rotating shaft 4 to rotate continuously and stably, providing a power basis for subsequent precooling and auxiliary freeze-drying operations;

[0058] S2:: Before the rotating shaft 4 rotates, open the threaded cover at the top of the feeding hopper 5 and add the camellia chrysantha material into the feeding hopper 5. Since the rotating shaft 4 is in sealed contact with the sleeve 7 and the feeding hopper 5 is fixedly connected to the sleeve 7 through the connecting piece 6, during normal operation, the internal space of the sleeve 7 is relatively sealed, preventing cold air leakage. When the rotating shaft 4 starts to rotate, the connecting rod 15 fixedly connected to the rotating shaft 4 also rotates accordingly. During the rotation of the sphere two 16 at the other end of the connecting rod 15, it will intermittently contact and collide with the sphere one 14. The sphere one 14 is fixedly installed on the side of the barrier net plate 13. When the sphere two 16 impacts the sphere one 14, it will give the barrier net plate 13 an impact force in the horizontal direction. Since the barrier net plate 13 is slidably installed on the feeding hopper 5, under the action of this impact force, the barrier net plate 13 overcomes the elastic force of the spring one 18 and slides horizontally along the feeding hopper 5. When the sphere two 16 rotates past the position where it contacts the sphere one 14, under the elastic force of the spring one 18, the barrier net plate 13 will slide back to the initial position. In this way, the barrier net plate 13 makes a reciprocating horizontal slide in the feeding hopper 5;

[0059] S3: During the reciprocating sliding of the barrier mesh plate 13, on the one hand, the mesh holes opened at its top allow part of the cold air in the sleeve 7 to pass through, pre-cooling the camellia flower material in the feeding hopper 5 and reducing the initial temperature of the material before it enters the freeze-drying cylinder 2, which helps improve the subsequent freeze-drying efficiency. Moreover, as the barrier mesh plate 13 reciprocates, the camellia flower material can be intermittently fed through the feeding hopper 5 and fall into the freeze-drying cylinder 2. On the other hand, when the rotating shaft 4 rotates, the second bevel gear 21 fixedly sleeved on its outer side rotates accordingly. Since the first bevel gear 20 meshes with the second bevel gear 21, the rotation of the second bevel gear 21 drives the first bevel gear 20 to rotate, and then the stirring member 19 fixedly connected to the first bevel gear 20 rotates in the feeding hopper 5. The rotation of the stirring member 19 stirs the camellia flower material, making the material evenly heated and cooled during the pre-cooling process, further enhancing the pre-cooling effect, and at the same time preventing the material from accumulating and ensuring that the material can smoothly enter the freeze-drying cylinder 2;

[0060] S4: After the cold air generated by the refrigerator 3 enters the sleeve 7 through the cold air pipe 8, the cold air after impinging on the paddle 11 enters the inside of the rotating shaft 4 through the air inlet hole 12 opened on the rotating shaft 4 in sealed contact with the sleeve 7. Since the rotating shaft 4 is of a hollow structure and the stirring rod 22 is fixedly installed on the outer side of the rotating shaft 4, and the air vent holes on the stirring rod 22 are communicated with the inside of the rotating shaft 4, the cold air can enter the stirring rod 22 from the inside of the rotating shaft 4;

[0061] S5: When the rotating shaft 4 rotates, it drives the stirring rod 22 to rotate together in the freeze-drying cylinder 2. During the rotation of the stirring rod 22, it stirs the camellia flower material in the freeze-drying cylinder 2, making its distribution more uniform and avoiding the situation of uneven local freeze-drying. At the same time, inside the stirring rod 22, under the combined action of centrifugal force and cold air pressure, the sealing piston 23 will slide along the axial direction of the stirring rod 22. When the sealing piston 23 slides outwards, the air outlet hole 24 originally blocked by the sealing piston 23 opens, and the cold air jets out from the air outlet hole 24 and directly acts on the camellia flower material. Since the sealing piston 23 intermittently opens the air outlet hole 24 to jet air during the rotation of the stirring rod 22, pulsed jetting of the camellia flower material can be realized, further improving the freeze-drying efficiency;

[0062] S6: The sealing piston 23 is fixedly connected to the baffle plate 27 through the cross bar 26. The cross bar 26 is slidably installed on the inner plate 25, and the second spring 28 is fixedly installed between the sealing piston 23 and the inner plate 25. When the centrifugal force and cold air pressure decrease, under the elastic force of the second spring 28, the sealing piston 23 slides inwards to close the air outlet hole 24, and so on in a cycle to ensure the stable progress of the jetting process. When the camellia flower is freeze-dried, the discharge valve on the discharge pipe is opened, and the material is discharged from the discharge pipe under its own gravity.

[0063] The above has introduced in detail an energy-saving refrigeration device for freeze-drying camellia nitidissima provided by the present invention. Specific embodiments are applied in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention.
