Technical Field

[0001] The invention belongs to the technical field of animal oil refining, in particular to a device for boiling and refining animal oil, a feed raw material. Background Art

[0002] Animal oils and fats contain a variety of fatty acids and are rich in nutrients. They are widely used in the food industry. In the production process of oils and fats, the crushed fat needs to be boiled to extract animal oil.

[0003] At present, when animal fat is boiled, it is necessary to heat the fat through a heating mechanism in a boiling container. After the animal oil is boiled and refined, it is necessary to manually use a salvaging machine to salvage the fat residue in the oil, so that the refined animal oil does not contain fat residue, thereby improving the quality of the oil. However, manually salvaging the fat residue with the help of a salvaging machine is not only time-consuming and labor-intensive, but also requires waiting for the oil temperature to drop before the residue can be salvaged, thereby affecting the refining efficiency of the entire animal oil.

[0007] The lower part of the side wall of the boiling cylinder is provided with an oil drain pipe, a valve is provided inside the oil drain pipe, and the boiling cylinder is fixedly arranged on the inner side of the bracket plate.

[0008] The heating component is arranged at the inner bottom of the boiling cylinder and is used to heat the animal fat.

[0009] The mesh stirring components are provided with two groups, and the two groups of mesh stirring components are arranged inside the boiling cylinder and fit each other.

[0010] The first driving assembly is mounted on the top of the support plate and is used to drive the two groups of mesh stirring assemblies to rotate synchronously inside the boiling cylinder to stir the animal fat.

When the boiling and refining of animal oil is completed, the second driving component can be used to drive one of the mesh stirring components to rotate relative to the other mesh stirring component, so that the two originally attached mesh stirring components are respectively unfolded on both sides of the drain pipe. At this time, the valve inside the drain pipe is opened, and the animal oil inside the boiling cylinder is discharged through the opened drain pipe. In this process, since the two mesh stirring components are respectively unfolded on both sides of the drain pipe, the two mesh stirring components can block the fat residues in the animal oil, so as to prevent the fat residues from being discharged together with the animal oil, realizing the automatic separation of animal oil and fat residues. Compared with the prior art, when the animal oil is discharged after boiling, the fat residues can be automatically isolated inside the boiling cylinder, thus realizing the automatic separation of animal oil and fat residues, and improving the refining quality and efficiency of animal oil.

Detailed implementation manner

[0030] The technical solution of the present invention will be further described in detail below in conjunction with the specific implementation manner.

[0031] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0032] Please refer to Figure 1 and Figure 2 , this embodiment provides a device for boiling and refining animal oil in feed raw materials, including a support plate 10, a boiling cylinder 20, a heating component 30, a mesh stirring component 40, a first driving component 50 and a second driving component 60. A drain pipe 201 is arranged at the lower part of the side wall of the boiling cylinder 20, and a valve (not shown in the figure) is arranged inside the drain pipe 201. The boiling cylinder 20 is fixedly arranged inside the support plate 10. The heating component 30 is arranged at the bottom inside the boiling cylinder 20 and is used for heating animal fat. There are two groups of the mesh stirring components 40, and the two groups of the mesh stirring components 40 are arranged inside the boiling cylinder 20 and are mutually attached. The first driving component 50 is installed on the top of the support plate 10 and is used to drive the two groups of the mesh stirring components 40 to rotate synchronously inside the boiling cylinder 20 to stir the animal fat. The second driving component 60 is installed on the inner wall of the boiling cylinder 20. After the animal oil is boiled, the second driving component 60 is used to drive one group of the mesh stirring components 40 to rotate relative to the other group of the mesh stirring components 40, so that the two groups of the mesh stirring components 40 are unfolded on the opposite sides of the drain pipe 201 to block the fat residues in the animal oil.

[0033] When it is necessary to boil animal fat, the animal fat can be placed inside the boiling cylinder 20, and then the heating component 30 is used to heat the animal fat, so as to realize the boiling and refining of animal oil. In the above process, the first driving component 50 can drive two mutually attached net-shaped stirring components 40 to rotate synchronously along the inner side of the boiling cylinder 20, and then stir the animal fat to make the animal fat evenly heated, so as to improve the boiling and refining effect of animal oil. When the boiling and refining of animal oil is completed, the second driving component 60 can be used to drive one of the net-shaped stirring components 40 to rotate relative to the other net-shaped stirring component 40, so that the two originally attached net-shaped stirring components 40 are respectively unfolded on opposite sides of the drain pipe 201. At this time, the valve inside the drain pipe 201 is opened, and the animal oil inside the boiling cylinder 20 is discharged through the opened drain pipe 201. In this process, since the two net-shaped stirring components 40 are respectively unfolded on opposite sides of the drain pipe 201, the two net-shaped stirring components 40 can block the fat residues in the animal oil, so as to prevent the fat residues from being discharged together with the animal oil, realizing the automatic separation of animal oil and fat residues.

[0034] Please refer to Figure 1 , in one embodiment, the first driving component 50 includes a rotating shaft 501 and a motor 502. The motor 502 is fixedly installed on the top of the support plate 10. One end of the rotating shaft 501 is connected to the output end of the motor 502, and the other end extends into the boiling cylinder 20. The two net-shaped stirring components 40 have the same structure, and both include a first side rod 401, a stirring net 402 and a second side rod 403. The first side rod 401 is vertically distributed on the inner side of the boiling cylinder 20, and the first side rod 401 is in contact with the inner wall of the boiling cylinder 20. There are two second side rods 403, and the two second side rods 403 are horizontally distributed on the inner side of the boiling cylinder 20. One end of the two second side rods 403 is connected to the rotating shaft 501, and the other ends are respectively fixedly connected to the upper and lower ends of the first side rod 403. A rectangular frame structure is formed among the rotating shaft 501, the first side rod 401 and the two side rods 403, and the stirring net 402 is embedded inside the rectangular frame structure.

[0035] Initially, the two sets of first side rods 401 corresponding to the two sets of mesh stirring assemblies 40 are kept vertically attached to each other, so that the stirring meshes 402 corresponding to the two sets of mesh stirring assemblies 40 are in a close state. When the heating assembly 30 heats the animal fat, the motor 502 can drive the rotation of the rotating shaft 501, and then drive the first side rods 401, the second side rods 403 and the stirring meshes 402 corresponding to the two sets of mesh stirring assemblies 40 to rotate. When the stirring meshes 402 rotate, they stir the animal fat, so that the animal fat is evenly heated, to improve the boiling and refining effect of animal oil. And as the animal oil is continuously refined from the fat, when the stirring meshes 402 rotate, the liquid animal oil can pass through the stirring meshes 402, while the fat residue is continuously pushed by the stirring meshes 402, and then moves in the animal oil.

[0036] Please refer to Figure 3 and Figure 4 , in one embodiment, the first side rod 401 has a circular structure. One end of the second side rod 403 corresponding to one set of the mesh stirring assemblies 40, which is far away from the corresponding first side rod 401, is hinged to the rotating shaft 501, and one end of the second side rod 403 corresponding to the other set of the mesh stirring assemblies 40, which is far away from the corresponding first side rod 401, is fixedly connected to the rotating shaft 501. A notch 202 is formed in the inner wall of the boiling cylinder 20 on one side of the drain pipe 201. The second driving assembly 60 includes a first baffle 601, a support shaft 602, a second elastic member 603 and a second baffle 604. One end of the support shaft 602 is rotatably connected to the first baffle 601, and the other end is fixedly connected to the inner top wall of the notch 202. The second baffle 604 is hinged to the side wall of the first baffle 601. One end of the second baffle 604, which is far away from the first baffle 601, extends to the inner area of the boiling cylinder 20. One end of the second elastic member 603 is connected to the first baffle 601, and the other end is connected to the second baffle 604, for providing elastic support for the second baffle 604.

[0037] When the motor 502 drives the rotating shaft 501 to rotate, and then drives the first side rods 401, the stirring nets 402 and the second side rods 403 corresponding to the two sets of mesh stirring assemblies 40 to rotate inside the boiling cylinder 20, the first baffle 601 is received inside the notch 202, and the end of the second baffle 604 away from the first baffle 601 extends to the inner area of the boiling cylinder 20. As the two sets of first side rods 401 rotate, the two sets of first side rods 401 can act on the part of the second baffle 604 extending to the inner area of the boiling cylinder 20, and then push the second baffle 604 to rotate the second baffle 604 relative to the first baffle 601, so that the second elastic member 603 is compressed. When the two sets of first side rods 401 pass over the second baffle 604, the second elastic member 603 pushes the second baffle 604 to rotate the second baffle 604 in the reverse direction, and then the end of the second baffle 604 away from the first baffle 601 extends to the inner area of the boiling cylinder 20 again. At this time, the second baffle 604 cannot limit the rotation of the two sets of first side rods 401, so that the two sets of first stirring nets 402 always remain close during the rotation process; when the animal oil is boiled, the motor 502 can be used to drive the rotating shaft 501 to rotate in the reverse direction, and then drive the first side rods 401, the stirring nets 402 and the second side rods 403 corresponding to the two sets of mesh stirring assemblies 40 to rotate in the reverse direction inside the boiling cylinder 20. When the two sets of first side rods 401 rotate in the reverse direction, the first side rods 401 on the second side rods 403 fixedly connected to the rotating shaft 502 can act on the part of the second baffle 604 extending to the inner area of the boiling cylinder 20 in advance. The second baffle 604 is pushed and pulls the first baffle 601 through the second elastic member 603, so that the first baffle 601 rotates relative to the support shaft 602. When the first baffle 601 rotates, one end of it rotates from inside the notch 201 to inside the boiling cylinder 20 and is inserted between the two sets of first side rods 401, while the second baffle 604 rotates in the reverse direction into the notch 201. Then, as the rotating shaft 501 continues to rotate in the reverse direction, the first side rods 401 on the second side rods 403 fixedly connected to the rotating shaft 502 continue to rotate in the reverse direction, while the first side rods 401 on the second side rods 403 hinged to the rotating shaft 502 are intercepted by the first baffle 601 and stop rotating. Until the first side rods 401 on the second side rods 403 fixedly connected to the rotating shaft 502 pass over the position of the drain pipe 201, the stirring nets 402 corresponding to the two sets of mesh stirring assemblies 40 are unfolded in a V shape on both sides of the drain pipe 201. At this time, the staff can open the valve inside the drain pipe 201 to discharge the animal oil inside the boiling cylinder 20 from the drain pipe 201. During the discharge of the animal oil, the two sets of stirring nets 402 block the fat residues in the animal oil.

[0038] Please refer to Figure 4, in one embodiment, a limiting block 203 is fixedly arranged on the inner bottom wall of the notch 201. When one end of the first baffle 601 rotates into the inside of the boiling cylinder 20 and is inserted between the two first side rods 401, the limiting block 203 acts on the side wall of the first baffle 601 to limit the first baffle 601, so that the first baffle 601 can stably intercept the corresponding first side rod 401, and the two stirring meshes 402 can be smoothly unfolded.

[0039] Please refer to Figure 3 , in one embodiment, the two second side rods 403 corresponding to the two mesh stirring assemblies 40 are connected by a first elastic member 404. The first elastic member 404 is used to provide an elastic pulling force to the two second side rods 403, so that when the animal fat is put into the inside of the boiling cylinder 20, the two stirring meshes 402 are kept close to each other, thereby preventing the animal fat from straying between the two stirring meshes 402, and ensuring that there is no fat residue between the two stirring meshes 402 after they are unfolded subsequently.

[0040] In one embodiment, the first elastic member 404 and the second elastic member 603 can be springs or metal shrapnel, and there is no limitation here.

[0041] In one embodiment, the heating assembly 30 is an electric heating plate embedded in the inner bottom wall of the boiling cylinder 20, or can be an electric heating wire wound on the inner bottom wall of the boiling cylinder 20, and there is no limitation here.

[0042] In the embodiment of the present invention, when it is necessary to boil animal fat, the animal fat can be placed inside the boiling cylinder 20, and then the heating component 30 is used to heat the animal fat, so as to realize the boiling and refining of animal oil. In the above process, the first driving component 50 can drive two mutually attached mesh stirring components 40 to rotate synchronously along the inner side of the boiling cylinder 20, and then stir the animal fat, so that the animal fat is evenly heated, so as to improve the boiling and refining effect of animal oil. When the boiling and refining of animal oil is completed, the second driving component 60 can be used to drive one of the mesh stirring components 40 to rotate relative to the other mesh stirring component 40, so that the two originally attached mesh stirring components 40 are respectively unfolded on the opposite sides of the drain pipe 201. At this time, the valve inside the drain pipe 201 is opened, and the animal oil inside the boiling cylinder 20 is discharged through the opened drain pipe 201. In this process, since the two mesh stirring components 40 are respectively unfolded on the opposite sides of the drain pipe 201, the two mesh stirring components 40 can block the fat residues in the animal oil, so as to prevent the fat residues from being discharged together with the animal oil, realizing the automatic separation of animal oil and fat residues. Compared with the prior art, when the animal oil is boiled and discharged, the fat residues can be automatically isolated inside the boiling cylinder 20, thus realizing the automatic separation of animal oil and fat residues, and improving the refining quality and efficiency of animal oil.

[0043] The above describes the preferred embodiments of the present invention in detail. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the spirit of the present invention.
