Abstract
Description
Technical Field
[0001] This utility model relates to the field of cheese processing technology, and more specifically, to a cheese whey separation device. Background Technology
[0002] Whey separation is a crucial step in cheese making. During cheese making, the proteins and fats in milk coagulate under acidic or enzymatic conditions, forming curds, while the remaining liquid is whey. This separation directly affects the cheese's taste, texture, and nutritional value. Effective separation yields cheese products with a smooth texture and rich flavor.
[0003] However, the whey formation process requires the catalytic enzyme to fully mix with the protein in the milk. In traditional devices, due to the use of a single stirring structure, the milk in the lower part of the reaction vessel cannot be circulated upwards, thus failing to achieve high efficiency in curd formation. Consequently, some protein remains in the curd, affecting the cheese production rate. Therefore, it is necessary to improve and optimize a cheese whey separation device. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this invention provides a cheese whey separation device, which has the advantage of a more thorough reaction between milk and catalytic enzymes, resulting in high cheese production efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cheese whey separation device, comprising a separation vessel, a stirring structure disposed inside the separation vessel, a fixed frame fixedly connected inside the separation vessel, a fixed rod fixedly connected inside the fixed frame, a first gear fixedly connected to the surface of the fixed rod, a stirring rod fixedly connected to the surface of the stirring structure, a second gear rotatably connected inside the stirring rod, and a third gear rotatably connected inside the stirring rod. The second gear meshes with the first gear, and the second gear meshes with the third gear. A stirring paddle is fixedly connected inside the third gear, and the middle part of the stirring paddle is rotatably connected to the inside of the stirring rod.
[0006] As a preferred technical solution of this utility model: the stirring structure includes a T-shaped frame fixedly connected to the upper surface of the separation vessel, a motor fixedly connected to the upper surface of the T-shaped frame, a hollow stirring shaft fixedly connected to the output shaft of the motor, a connecting strip fixedly connected to the surface of the hollow stirring shaft, a vertical stirring rod fixedly connected to the lower surface of the connecting strip, the surface of the hollow stirring shaft fixedly connected to the end of the stirring rod near the first gear, the lower part of the hollow stirring shaft rotatably connected to the interior of the fixed frame, and the surface of the hollow stirring shaft rotatably connected to the interior of the separation vessel.
[0007] As a preferred technical solution of this utility model: a fixing hoop is fixedly connected to the outer surface of the separation vessel, a support frame is fixedly connected to the surface of the fixing hoop, and a fixing strip is fixedly connected to the inner side of the support frame.
[0008] As a preferred technical solution of this utility model: a milk inlet is fixedly connected to the upper surface of the separation vessel, and a catalyst inlet is fixedly connected to the upper surface of the separation vessel.
[0009] As a preferred technical solution of this utility model: an observation window is provided at the front of the separation vessel, and a piston is movably connected to the front of the separation vessel.
[0010] As a preferred technical solution of this utility model: a filter screen is fixedly connected inside the separation vessel, and a whey discharge port is fixedly connected to the lower part of the separation vessel.
[0011] As a preferred technical solution of this utility model: the surface of the hollow stirring shaft is provided with a through hole, the through hole is movably connected to the first gear, and the through hole is movably connected to the second gear.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model uses the rotation of the stirring structure to drive the rotation of the hollow stirring shaft. The rotation of the hollow stirring shaft drives the rotation of the stirring rod, which in turn drives the second gear, the third gear, and the stirring paddle inside the stirring rod to rotate along the fixed rod as the axis. At the same time, due to the meshing between the first gear and the second gear, and the meshing between the second gear and the third gear, the stirring paddle rotates on its own along with the rotation of the stirring rod. This device uses the rotation of the stirring paddle to turn the milk at the bottom of the separation vessel back up, so that the reaction between the milk and the catalytic enzyme is more thorough, resulting in high cheese production efficiency.
[0014] 2. This utility model provides support for the motor through a T-shaped frame, increasing the contact area between the motor and the air, which is beneficial for heat dissipation during motor operation. At the same time, the rotation of the motor output shaft drives the rotation of the hollow stirring shaft, which in turn drives the rotation of the stirring rod and the vertical stirring rod. This allows the fixing hoop to stir the reaction liquid inside the separation vessel, resulting in more complete separation of cheese whey and avoiding insufficient mixing of milk and catalytic enzymes, which would result in a small amount of cheese formed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 6 As shown, this utility model provides a cheese whey separation device, including a separation vessel 1. The separation vessel 1 is equipped with a stirring structure. A fixing frame 2 is fixedly connected inside the separation vessel 1. A fixing rod 3 is fixedly connected inside the fixing frame 2. A first gear 4 is fixedly connected to the surface of the fixing rod 3. A stirring rod 5 is fixedly connected to the surface of the stirring structure. A second gear 6 is rotatably connected inside the stirring rod 5. A third gear 7 is rotatably connected inside the stirring rod 5. The second gear 6 meshes with the first gear 4. The second gear 6 meshes with the third gear 7. A stirring paddle 8 is fixedly connected inside the third gear 7. The middle part of the stirring paddle 8 is rotatably connected to the inside of the stirring rod 5.
[0024] When the staff needs to separate the whey from the cheese, milk and catalyst are injected into the separation vessel 1 through the milk inlet 17 and catalyst inlet 18, respectively. At this time, the stirring structure is activated, which drives the hollow stirring shaft 11 to rotate inside the fixed frame 2. Since the fixed rod 3 is fixedly connected inside the fixed frame 2, when the hollow stirring shaft 11 rotates, it drives the stirring rod 5 to rotate, which in turn drives the second gear 6 to rotate along the fixed rod 3. Since the first gear 4 and the second gear 6 mesh with each other, the second gear 6 rotates. At the same time, since the second gear 6 and the third gear 7 mesh with each other, the third gear 7 rotates inside the stirring rod 5, which in turn drives the stirring paddle 8 to rotate.
[0025] The stirring structure includes a T-shaped frame 9 fixedly connected to the upper surface of the separation vessel 1. A motor 10 is fixedly connected to the upper surface of the T-shaped frame 9. A hollow stirring shaft 11 is fixedly connected to the output shaft of the motor 10. A connecting strip 12 is fixedly connected to the surface of the hollow stirring shaft 11. A vertical stirring rod 13 is fixedly connected to the lower surface of the connecting strip 12. The surface of the hollow stirring shaft 11 is fixedly connected to the end of the stirring rod 5 near the first gear 4. The lower part of the hollow stirring shaft 11 is rotatably connected to the interior of the fixed frame 2. The surface of the hollow stirring shaft 11 is rotatably connected to the interior of the separation vessel 1.
[0026] When the operator starts the motor 10, the T-shaped frame 9 provides support for the motor 10, and the rotation of the output shaft of the motor 10 drives the rotation of the hollow stirring shaft 11. Then, since the stirring rod 5 is fixedly connected to the surface of the hollow stirring shaft 11, the stirring rod 5 stirs the milk and catalytic enzyme inside the separation vessel 1. Furthermore, the rotation of the output shaft of the hollow stirring shaft 11 drives the rotation of the connecting strip 12. At the same time, the vertical stirring rod 13 rotates along the hollow stirring shaft 11 as the axis, causing the milk to react with the catalytic enzyme, decompose the protein in the milk, and coagulate it into curd.
[0027] Among them, a fixing hoop 14 is fixedly connected to the outer surface of the separation vessel 1, a support frame 15 is fixedly connected to the surface of the fixing hoop 14, and a fixing strip 16 is fixedly connected to the inner side of the support frame 15.
[0028] By fixing the separator 1 to the inside of the fixing hoop 14 and supporting the fixing hoop 14 with the support frame 15, the separator 1 is placed at a certain height, which helps the whey to be discharged from the bottom. At the same time, the fixing strip 16 strengthens the supporting force of the support frame 15.
[0029] The upper surface of the separator 1 is fixedly connected to a milk inlet 17 and a catalyst inlet 18.
[0030] Milk is injected into the interior of the separator 1 through the milk inlet 17, and catalytic enzymes are injected into the interior of the separator 1 through the catalyst inlet 18.
[0031] The separation vessel 1 has an observation window 19 at the front and a piston 20 is movably connected to the front of the separation vessel 1.
[0032] The cheese formation inside the separator 1 can be observed through the observation window 19, and the cheese is collected and the inside of the separator 1 is cleaned by opening the piston 20 after whey separation is completed.
[0033] The separator 1 is equipped with a filter screen 21, and the lower part of the separator 1 is equipped with a whey discharge port 22.
[0034] The cheese is separated from the whey by the filter screen 21, while the whey discharge port 22 can filter and discharge the whey that has passed through the filter screen 21.
[0035] The hollow stirring shaft 11 has a through hole 23 on its surface, which is movably connected to the first gear 4 and the second gear 6.
[0036] The design of the through hole 23 ensures that when the hollow stirring shaft 11 rotates, the first gear 4 located inside the hollow stirring shaft 11 can mesh with the second gear 6, thereby ensuring the stability of the stirring paddle 8 rotation.
[0037] Working principle and usage process of this utility model:
[0038] When the staff needs to separate the whey from the cheese, milk and catalyst are injected into the separation vessel 1 through the milk inlet 17 and catalyst inlet 18, respectively. At this time, the stirring structure is activated, which drives the hollow stirring shaft 11 to rotate inside the fixed frame 2. Since the fixed rod 3 is fixedly connected inside the fixed frame 2, when the hollow stirring shaft 11 rotates, it drives the stirring rod 5 to rotate, which in turn drives the second gear 6 to rotate along the fixed rod 3. Since the first gear 4 and the second gear 6 mesh with each other, the second gear 6 rotates. At the same time, since the second gear 6 and the third gear 7 mesh with each other, the third gear 7 rotates inside the stirring rod 5, which in turn drives the stirring paddle 8 to rotate.
[0039] When the operator starts the motor 10, the T-shaped frame 9 provides support for the motor 10, and the rotation of the output shaft of the motor 10 drives the rotation of the hollow stirring shaft 11. Then, since the stirring rod 5 is fixedly connected to the surface of the hollow stirring shaft 11, the stirring rod 5 stirs the milk and catalytic enzyme inside the separation vessel 1. Furthermore, the rotation of the output shaft of the hollow stirring shaft 11 drives the rotation of the connecting strip 12. At the same time, the vertical stirring rod 13 rotates along the hollow stirring shaft 11 as the axis, causing the milk to react with the catalytic enzyme, decompose the protein in the milk, and coagulate it into curd.
[0040] By fixing the separator 1 to the inside of the fixing hoop 14 and supporting the fixing hoop 14 with the support frame 15, the separator 1 is placed at a certain height, which helps the whey to be discharged from the bottom. At the same time, the fixing strip 16 strengthens the supporting force of the support frame 15.
[0041] Milk is injected into the interior of the separator 1 through the milk inlet 17, and catalytic enzymes are injected into the interior of the separator 1 through the catalyst inlet 18.
[0042] The cheese formation inside the separator 1 can be observed through the observation window 19, and the cheese is collected and the inside of the separator 1 is cleaned by opening the piston 20 after whey separation is completed.
[0043] The cheese is separated from the whey by the filter screen 21, while the whey discharge port 22 can filter and discharge the whey that has passed through the filter screen 21.
[0044] The design of the through hole 23 ensures that when the hollow stirring shaft 11 rotates, the first gear 4 located inside the hollow stirring shaft 11 can mesh with the second gear 6, thereby ensuring the stability of the stirring paddle 8 rotation.
