Description

Technical Field

[0001] This utility model relates to the field of cheese processing technology, and in particular to a double-cylinder spiral heating and anti-scorching concentration device for cheese liquid. Background Technology

[0002] In the industrial production of cheese powder, the cheese liquid concentration process is a core step that determines the product's quality, flavor, and shelf life. By precisely removing excess water from the cheese liquid, the milk solids content can be significantly increased, laying the foundation for subsequent key processes such as curd formation and flavor accumulation during aging. This directly affects the texture and market competitiveness of the final cheese product and also provides high-quality raw materials for the processing of derivative products such as cheese powder. To achieve efficient and uniform concentration of cheese liquid, medium and large-sized production enterprises in the industry generally adopt a double-layer sleeve structure concentration device. The core design lies in the nesting of the outer and inner cylinders, forming a closed annular heating chamber between the two cylinders. The built-in heat-conducting medium can continuously provide stable and uniform heat to the cheese liquid inside the inner cylinder, accurately meeting the temperature conditions required for the evaporation of moisture in the cheese liquid. However, the cheese liquid is in a relatively static or slow-flowing state during the concentration process, which causes the material near the cylinder wall to be continuously subjected to high temperature, while the material inside is not heated enough, forming a significant temperature gradient and causing uneven heating. The high-temperature material near the cylinder wall is prone to sticking to the inner wall due to rapid moisture evaporation. The material sticking to the wall will gradually caramelize, not only contaminating the cheese liquid inside the inner cylinder, but also forming a heat insulation layer on the cylinder wall, hindering the transfer of heat from the annular heating chamber to the internal material, and affecting the processing stability. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the function of the double-cylinder spiral is limited to single conveying, and the stirring effect is insufficient, which leads to uneven heating of materials during the conveying process, resulting in serious risk of sticking and charring, and affecting the processing stability. To this end, we propose a double-cylinder spiral heating anti-charring concentration device for cheese liquid.

[0004] To achieve the above objectives, this application adopts the following technical solution: a double-cylinder spiral heating anti-scorching concentration device for cheese liquid, comprising a mounting frame and a heating cylinder fixedly disposed on the upper end of the mounting frame. A power unit is mounted on one side of the mounting frame, and a transmission wheel set is mounted on the output end of the power unit. The transmission wheel set is provided with two sets of output shafts, and the two sets of output shafts are respectively fixedly connected to a first output stirring assembly and a second output stirring assembly. The first output stirring assembly and the second output stirring assembly have the same composition structure. The first output stirring assembly includes a rotating roller body fixedly connected to the output shaft. A threaded feeding body is installed on the outer wall of the rotating roller body, and a stirring rod is fixedly connected to the outer wall of the rotating roller body. The stirring rod is a component made of rubber material, and it is squeezed and bent when the stirring rod rotates to one end of the inner wall of the heating cylinder.

[0005] Furthermore, the stirring rods are provided in multiple sets, and the multiple sets of stirring rods are evenly and alternately arranged about the outer wall of the roller body.

[0006] Furthermore, the stirring rod includes a rod body fixedly connected to the rotating roller body. The rod body has an elastic cavity inside, dividing the interior of the rod body into a solid part and a hollow part. The hollow part of the rod body is elastic and deformable.

[0007] Furthermore, a rubber elastic column is fixedly connected to the inner wall of the elastic cavity.

[0008] Furthermore, multiple sets of the rubber elastic columns are provided, and they are all evenly distributed about the inner wall of the elastic cavity.

[0009] The technical effects and advantages of this utility model are as follows: In this invention, during the entire operation, the power unit drives two sets of output stirring components to operate synchronously through the transmission wheel set. The threaded feeding unit guides the orderly flow of materials, avoiding local accumulation. Multiple sets of staggered elastic stirring rods simultaneously achieve all-round stirring of materials and cleaning of the cavity wall. Combined with the stable heat provided by the heating unit inside the heating cylinder, the cheese liquid is kept in a uniformly mixed state and evenly heated during the concentration process. This completely avoids the hidden dangers of uneven heating of materials and charring due to sticking to the wall, significantly improving the processing stability of cheese liquid concentration and the quality of the final product. It solves the problem of uneven overall heating, where high-temperature materials near the cylinder wall are prone to sticking to the inner wall due to rapid evaporation of moisture. The sticking material will gradually char, not only contaminating the cheese liquid inside the inner cylinder, but also forming a heat insulation layer on the cylinder wall, hindering the transfer of heat from the annular heating cavity to the internal materials, and affecting the processing stability.

[0012] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0013] Reference Figures 1-4 As shown, to address the issue of uneven heating, where high-temperature materials near the cylinder wall tend to adhere to the inner wall due to rapid moisture evaporation, and this adhered material gradually caramelizes, not only contaminating the cheese liquid inside the cylinder but also forming a heat insulation layer on the cylinder wall, hindering heat transfer from the annular heating chamber to the internal materials and affecting processing stability, the following preferred technical solution is provided: A dual-cylinder spiral heating and anti-scorching concentration device for cheese liquid includes a mounting frame 1 and a heating cylinder 2 fixedly mounted on the upper end of the mounting frame 1. The device uses the mounting frame 1 as the overall support base, and the heating cylinder 2 fixed at its upper end consists of an inner cylinder and an outer cylinder forming a double-layer sleeve structure. An annular heating chamber is formed between the outer cylinder and the inner cylinder, and spiral heat-conducting oil channels are evenly distributed in the annular heating chamber to provide a stable heat source for the cheese liquid. The power unit 3 on one side of the mounting frame 1, such as a geared motor, provides power for stirring and conveying. The transmission wheel set 4 connected to its output end splits the power to two sets of output shafts through gear meshing or chain transmission, which drive the first output stirring component 5 and the second output stirring component 6 to operate synchronously, ensuring that the two sets of stirring components rotate in opposite directions and at the same speed, thereby enhancing the mixing effect of the materials. The first output stirring assembly 5 and the second output stirring assembly 6 have the same structure. Taking the first output stirring assembly 5 as an example, it includes a rotating roller body 51, which is fixedly connected to the output shaft of the transmission wheel set 4 and rotates synchronously with the output shaft. The outer wall of the rotating roller body 51 is equipped with a spirally distributed threaded feeding body 52, which can assist the cheese liquid to form an orderly flow in the inner cylinder during rotation, avoiding local accumulation of materials. The outer wall of the rotating roller body 51 is also fixed with a stirring rod 53. When the stirring rod 53 rotates synchronously with the roller, it can perform radial stirring of the cheese liquid, effectively breaking the stratification phenomenon formed by the material due to heating, and ensuring sufficient heat exchange of the cheese liquid in different areas of the inner cylinder. At the same time, the stirring rod 53 adopts a staggered distribution design, which can further enhance the convective mixing effect of the material, so that the cheese liquid always maintains a uniform mixing state during the concentration process, fundamentally solving the defect of insufficient stirring in traditional double-layer sleeve concentration devices, avoiding local overheating problems, and ensuring the uniformity of the composition of the concentrated material. The stirring rod 53 is made of rubber. When the stirring rod 53 rotates to one end of the inner wall of the heating cylinder 2, it is compressed and bent. The high elasticity of the rubber material allows the stirring rod 53 to bend and deform tightly against the inner wall surface when it is close to the inner wall of the heating cylinder 2, scraping off the cheese liquid adhering to the wall. After moving away from the inner wall, the stirring rod 53 returns to its original shape under its own elasticity, without affecting the overall stirring effect. This achieves integrated stirring and wall scraping, automatically removing residual materials from the cavity wall, fundamentally solving the risk of wall adhesion and charring, while avoiding wear on the cavity body from the metal wall scraper, thus extending the service life of the equipment. Multiple sets of stirring rods 53 are provided, and these sets of stirring rods 53 are evenly and alternately arranged around the outer wall of the roller body 51. This even and alternate arrangement creates a dense stirring zone during rotation, eliminating blind spots. Simultaneously, the alternate distribution reduces material vortex interference between adjacent stirring rods 53, ensuring uniform flow of the cheese liquid within the cavity. This eliminates dead zones, enhances material mixing uniformity, prevents overheating and coking due to prolonged material retention in certain areas, and ensures processing stability. The stirring rod 53 includes a rod body 531 fixedly connected to the roller body 51. An elastic cavity 532 is formed inside the rod body 531, dividing the interior of the rod body 531 into a solid part and a hollow part. The hollow part of the rod body 531 is elastic and deformable. The design of the elastic cavity 532 and the hollow part enhances the elastic deformation capacity of the rod body 531 while maintaining structural strength. When in contact with the inner wall of the cavity, the hollow part can absorb the impact force through compression, avoiding damage to components caused by rigid collisions. When returning to its original shape, the hollow structure can quickly rebound, ensuring stable wall scraping effect, balancing the rigidity and elasticity of the stirring rod, improving its deformation adaptability, ensuring the fit during wall scraping, and avoiding fatigue fracture caused by frequent deformation, thus extending the service life of the stirring rod. A rubber elastic column 533 is fixedly connected to the inner wall of the elastic cavity 532. The rubber elastic column 533 is distributed axially along the elastic cavity 532, providing additional support and elastic restoring force to the rod body 531. When the rod body 531 bends, the rubber elastic column 533 is compressed and stores energy. After moving away from the inner wall, the rebound force of the elastic column accelerates the rod body 531 to return to its original position, ensuring that the stirring rod can quickly return to its working posture after each wall scraping. This enhances the elastic restoring ability of the stirring rod, avoiding incomplete wall scraping due to deformation lag. Simultaneously, the buffering effect of the elastic column further reduces impact wear between the stirring rod and the cavity. Multiple sets of rubber elastic columns 533 are provided, and they are all evenly distributed around the inner wall of the elastic cavity 532. The evenly distributed multiple sets of rubber elastic columns 533 can provide uniform support and rebound force to the rod body 531, avoiding tilting and deformation of the rod body 531 due to excessive force on one side, and ensuring that the stirring rod 53 always maintains a symmetrical stirring trajectory. To ensure the symmetry of the deformation and reset of the stirring rod, to avoid uneven material mixing caused by deviation of the stirring trajectory, and at the same time to extend the structural stability of the rod body and reduce the frequency of maintenance.

[0014] Specifically, the main body 51 of the rotating roller serves as the core support. When the threaded feeding body 52 fixed on its outer wall rotates with the rotating roller, the threaded feeding body 52 guides the cheese liquid to form an orderly flow in the inner cylinder through the spiral pattern, avoiding local accumulation of materials and ensuring uniform material distribution in all areas of the cavity. At the same time, multiple sets of rubber stirring rods 53 are evenly and alternately arranged on the outer wall of the main body 51 of the rotating roller. These stirring rods 53 rotate synchronously with the main body 51 of the rotating roller, which can perform radial and all-round stirring of the cheese liquid in the cavity, breaking the stratification phenomenon caused by heat in the material, ensuring that heat is evenly transferred in the material, and avoiding local overheating problems from the source. The rod body 531 of the stirring rod 53 has an elastic cavity 532 inside, dividing the rod into two parts: solid and hollow. The hollow part has elastic deformation characteristics, and multiple sets of rubber elastic columns 533 evenly distributed on the inner wall of the elastic cavity 532 provide support and restoring force for the rod. When the stirring rod 53 rotates close to the inner wall of the heating cylinder 2, the rubber rod is squeezed and bent by the inner wall. This not only allows it to penetrate deep into the edge of the cavity to stir the accumulated cheese liquid, avoiding uneven heating in certain areas, but also removes the cheese liquid residue adhering to the cavity wall through the elastic scraping action when bent. After moving away from the cavity wall, the rubber elastic column 533 pushes the rod back to its original shape, ready for the next stirring and scraping action.

[0015] Throughout the operation, the power unit 3 drives two sets of output stirring components to operate synchronously through the transmission wheel set 4, and the threaded feeding body 52 guides the material to flow in an orderly manner to avoid local accumulation; multiple sets of staggered elastic stirring rods 53 simultaneously achieve all-round stirring of the material and cleaning of the cavity wall; together with the stable heat provided by the heating body in the heating cylinder 2, the cheese liquid is kept in a uniform mixing state and evenly heated during the concentration process, which completely avoids the hidden dangers of uneven heating of the material and charring of the wall, and significantly improves the processing stability of cheese liquid concentration and the quality of the final product.

[0016] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
