Description

Technical Field

[0001] The utility model relates to the technical field of food fermentation, in particular to a centrifugal device for producing fermented milk. Background Art

[0002] Fermented milk (yogurt) is an acidic curd-like product made by fermenting milk and dairy products under the action of characteristic bacteria. The characteristic bacteria of this type of product must exist in large quantities within the shelf life and continue to survive and be active. Existing fermented milk generally requires the use of centrifugal mixing equipment during production;

[0003] For example, the existing patent CN217218024U retrieved discloses a fermentation tank for fermented milk. The existing technology uses a stirring shaft to drive stirring blades to fully blend the raw materials in the tank;

[0004] However, the above-mentioned prior art has the following problems in the stirring process of fermented milk raw materials: when the existing fermented milk is fermented in a centrifugal stirring device, the sterile milk base (with a high concentration) and the sterile milk are poured into the tank body through a feed pipe in sequence, which will cause the fermented milk raw materials in the centrifugal stirring device to form layers. However, the stirring blades in the existing patents are generally stirred at a fixed position, which results in low stirring uniformity and a distinct layered taste. It takes more time to ensure that the fermented milk raw materials are mixed evenly, affecting the efficiency of fermented milk production. In response to the above problems, the inventor has designed a centrifugal device for fermented milk production. Utility Model Content

[0005] The utility model aims to provide a centrifugal device for fermented milk production, which solves the problem that the stirring blades in the background technology are generally fixed in position for stirring, which leads to low stirring uniformity, obvious layering of taste, and requires more time to ensure uniform mixing of the fermented milk raw materials.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a centrifugal device for producing fermented milk, comprising a tank body, a control shell being fixedly connected to the upper surface of the tank body, a rotating shaft being provided on the control shell, the lower end of the rotating shaft passing through the control shell, and finally rotating and penetrating into the tank body, a plurality of stirring blades being fixedly installed on the outer surface of the rotating shaft located in the tank body, two support plates being fixedly connected to the outer surface of the upper side of the control shell located on the rotating shaft, the two support plates being arranged in a mirror image, support pulleys being provided on the lower surfaces of the two support plates, the bottom of the support pulleys being in contact with the upper surface of the control shell and sliding, two arc-shaped protrusions being fixedly connected to the upper surface of the control shell, the two arc-shaped protrusions being centered on the rotating shaft and being arranged in a mirror image, the bottom of the support pulleys also being in contact with the arc-shaped surfaces of the arc-shaped protrusions and sliding.

[0007] By adopting the above technical solution, when the rotating shaft rotates, the support plate synchronously drives the support pulley to move in a circular direction on the control housing; when the support pulley slides from bottom to top along the arc-shaped surface of the arc-shaped protrusion, the support plate synchronously drives the rotating shaft to move upward; when the support pulley slides downward along the apex of the arc-shaped protrusion, the rotating shaft moves downward under the action of inertia.

[0008] As a further description of the above technical solution: a feeding head is fixedly installed on the upper surface of the tank body, a heating element is arranged in the tank body, a second bevel gear is sleeved on the outer surface of the rotating shaft located in the control shell, a motor is fixedly installed on the upper surface of the tank body, the motor output shaft rotates and passes through the control shell, a first bevel gear is fixedly installed on one end of the motor output shaft located in the control shell, and the first bevel gear is meshingly connected with the second bevel gear.

[0009] By adopting the above technical solution, the motor is started, the first bevel gear is synchronously engaged to drive the second bevel gear to rotate, so that the rotating shaft rotates with the second bevel gear, so that the stirring blade centrifugally stirs the fermented milk raw materials in the tank.

[0010] As a further description of the above technical solution: the second bevel gear is provided with a sliding hole that is slidably sleeved on the rotating shaft, and the inner wall of the sliding hole is provided with a plurality of limiting sliding grooves, which extend from the upper and lower side surfaces of the second bevel gear respectively, and the outer surface of the rotating shaft is provided with a plurality of limiting sliding blocks, which slide in the limiting sliding grooves.

[0011] By adopting the above technical solution, when the rotating shaft moves up and down, the second bevel gear will not move with the rotating shaft, thereby avoiding the problem of jamming between the second bevel gear and the first bevel gear as much as possible. At the same time, when the second bevel gear rotates, the rotating shaft can be driven to rotate synchronously by limiting the slider.

[0012] As a further description of the above technical solution: a plurality of hemispherical supporting sliders are fixedly connected to the lower surface of the second bevel gear, and the bottom of the supporting slider contacts and slides with the bottom wall of the control housing.

[0013] By adopting the above technical solution, the second bevel gear is supported by the supporting slider, which avoids the problem of the second bevel gear lacking support and falling on the bottom wall of the control housing as much as possible.

[0014] As a further description of the above technical solution: the interior of one end of the rotating shaft located in the tank body is hollow, and a plurality of groups of upper and lower diverter structures are provided on the end of the rotating shaft located in the tank body, and the upper and lower diverter structures include two driving shafts, and the two driving shafts are arranged in parallel in the rotating shaft, and both ends of the two driving shafts rotate to pass through the outer surface of the rotating shaft, and two toggle rods are fixedly connected at both ends of the driving shaft, and a diverter plate is fixedly connected between the two toggle rods, and a plurality of through holes are provided on the diverter plate, and a control slide is provided at the lower end of the rotating shaft, and a rotating base is fixedly connected to the lower side of the control slide, and a support frame is fixedly installed on the inner wall of the tank body, and the rotating base is rotatably connected to the support frame, and the upper side of the control slide slides slides into the rotating shaft, and teeth are provided on the surface of the control slide close to the driving shaft, and a gear is fixedly sleeved on the outer surface of one end of the driving shaft located in the rotating shaft, and the control slide is meshed with the gear through the teeth.

[0015] By adopting the above technical solution, when the rotating shaft is displaced upward, the control slide plate is restricted by the support frame and cannot move with the rotating shaft. Therefore, the gear rotates clockwise under the meshing transmission of the teeth, so that the deflector plates on both sides of the rotating shaft rotate upward to form a V shape. In this way, when the rotating shaft is displaced upward, the purpose of shifting the raw materials upward can be achieved. When the rotating shaft is displaced downward, the gear rotates counterclockwise under the meshing transmission of the teeth, so that the deflector plates on both sides of the rotating shaft rotate downward to form an inverted V shape, which can achieve the purpose of shifting the raw materials downward. In this way, the raw materials in the tank body can be fully fermented and reacted, thereby further improving the fermentation efficiency of the raw materials in the tank body.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] The utility model provides a centrifugal device for fermented milk production, which can drive the stirring blades to move up and down in the tank body. Therefore, in the case of horizontal centrifugal stirring, the fermented milk raw materials can also be stirred up and down, further improving the stirring efficiency of the fermented milk raw materials, so that the raw materials in the tank body can be fully fermented, and the fermentation time of the raw materials is reduced. At the same time, during the up and down displacement of the rotating shaft, the deflector plates on both sides of the rotating shaft can be rotated into a V shape or an inverted V shape, thereby improving the effect of stirring the raw materials in the tank body up and down, and further improving the fermentation efficiency of the raw materials in the tank body.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0027] Combination Figure 1-Figure 4 The utility model is a centrifugal device for fermented milk production, comprising a tank body 1, a feeding head 2 is fixedly installed on the upper surface of the tank body 1, and fermented milk raw materials are added into the tank body 1 through the feeding head 2, and a heating element is arranged in the tank body 1, and the heating element is a known technology and will not be described in detail here, so the heating element is started and emits heat, and the raw materials can be fermented to form fermented milk;

[0028] Specifically, a control housing 3 is fixedly connected to the upper surface of the tank body 1, and a rotating shaft 5 is provided on the control housing 3. The lower end of the rotating shaft 5 passes through the control housing 3 and finally rotates and penetrates into the tank body 1. A plurality of stirring blades 15 are fixedly installed on the outer surface of the rotating shaft 5 located in the tank body 1. A second bevel gear 8 is sleeved on the outer surface of the rotating shaft 5 located in the control housing 3. A motor 4 is fixedly installed on the upper surface of the tank body 1. In this embodiment, the motor 4 is a low-speed motor. The output shaft of the motor 4 rotates and penetrates into the control housing 3. A first bevel gear 6 is fixedly installed on one end of the output shaft of the motor 4 located in the control housing 3. The first bevel gear 6 is meshed and connected with the second bevel gear 8.

[0029] Therefore, when in use, the motor 4 is started, the first bevel gear 6 is synchronously meshed to drive the second bevel gear 8 to rotate, so that the rotating shaft 5 rotates with the second bevel gear 8, so that the stirring blade 15 centrifugally stirs the fermented milk raw material in the tank body 1, so that the fermented milk raw material is fermented more fully;

[0030] Specifically, the rotating shaft 5 is located on the outer surface of the upper side of the control housing 3, and two support plates 12 are fixedly connected. The two support plates 12 are arranged in a mirror image. The lower surfaces of the two support plates 12 are provided with support pulleys 13. The bottom of the support pulley 13 contacts and slides with the upper surface of the control housing 3. The upper surface of the control housing 3 is fixedly connected with two arc-shaped protrusions 14. The two arc-shaped protrusions 14 are arranged in a mirror image with the rotating shaft 5 as the center point. The bottom of the support pulley 13 also contacts and slides with the arc surface of the arc-shaped protrusion 14.

[0031] When the rotating shaft 5 rotates, the supporting plate 12 synchronously drives the supporting pulley 13 to move in the circumferential direction on the control housing 3. When the supporting pulley 13 slides from bottom to top along the arc surface of the arc-shaped protrusion 14, the supporting plate 12 synchronously drives the rotating shaft 5 to move upward. When the supporting pulley 13 slides downward along the vertex of the arc-shaped protrusion 14, the rotating shaft 5 moves downward under the action of inertia. In this way, the stirring blade 15 can be driven to move up and down in the tank body 1. Therefore, in the case of horizontal centrifugal stirring, the fermented milk raw materials can also be stirred up and down, further improving the stirring efficiency of the fermented milk raw materials, so that the raw materials in the tank body 1 can be fully fermented, and the fermentation time of the raw materials is reduced;

[0032] Specifically, the second bevel gear 8 is provided with a sliding hole slidably mounted on the rotating shaft 5, and a plurality of limiting sliding grooves 11 are provided on the inner wall of the sliding hole. The limiting sliding grooves 11 extend from the upper and lower side surfaces of the second bevel gear 8 respectively, and a plurality of limiting sliders 10 are provided on the outer surface of the rotating shaft 5. The limiting sliders 10 slide in the limiting sliding grooves 11. Therefore, when the rotating shaft 5 moves up and down, the second bevel gear 8 will not move with the rotating shaft 5, and the problem of jamming between the second bevel gear 8 and the first bevel gear 6 is avoided as much as possible. At the same time, when the second bevel gear 8 rotates, the rotating shaft 5 can be synchronously driven to rotate through the limiting sliders 10;

[0033] Specifically, a plurality of hemispherical support sliders 9 are fixedly connected to the lower surface of the second bevel gear 8, and the bottom of the support slider 9 contacts and slides with the bottom wall of the control housing 3. Therefore, the second bevel gear 8 is supported by the support slider 9, and the problem of the second bevel gear 8 falling on the bottom wall of the control housing 3 due to lack of support is avoided as much as possible;

[0034] Combination Figure 4 and Figure 5The end of the rotating shaft 5 located in the tank body 1 is hollow inside, and a plurality of groups of upper and lower flow-diverting structures are arranged on the end of the rotating shaft 5 located in the tank body 1. The number of the upper and lower flow-diverting structures can be set according to actual needs. The upper and lower flow-diverting structures include two driving shafts 18, which are arranged in parallel in the rotating shaft 5. Both ends of the two driving shafts 18 rotate and penetrate the outer surface of the rotating shaft 5. Two toggle rods 16 are fixedly connected to the two ends of the driving shaft 18, and a flow-diverting plate 17 is fixedly connected between the two toggle rods 16, and a plurality of through holes are opened on the flow-diverting plate 17;

[0035] Specifically, a control slide 20 is provided at the lower end of the rotating shaft 5, and a rotating base 22 is fixedly connected to the lower side of the control slide 20. A support frame 7 is fixedly installed on the inner wall of the tank body 1, and the rotating base 22 is rotatably connected to the support frame 7. The upper side of the control slide 20 slides through the rotating shaft 5. A tooth 21 is provided on the surface of the side of the control slide 20 close to the driving shaft 18. A gear 19 is fixedly sleeved on the outer surface of one end of the driving shaft 18 located in the rotating shaft 5, and the control slide 20 is meshed and connected with the gear 19 through the tooth 21.

[0036] When the rotating shaft 5 rotates, the control slide 20 rotates synchronously with the rotating shaft 5, and the rotating base 22 rotates on the support frame 7. When the rotating shaft 5 moves upward, since the control slide 20 is restricted by the support frame 7 and cannot move with the rotating shaft 5, the gear 19 rotates clockwise under the meshing transmission of the teeth 21, so that the deflector plates 17 on both sides of the rotating shaft 5 rotate upward in a V shape. In this way, when the rotating shaft 5 moves upward, the purpose of shifting the raw materials upward can be achieved. When the rotating shaft 5 moves downward, the gear 19 rotates counterclockwise under the meshing transmission of the teeth 21, so that the deflector plates 17 on both sides of the rotating shaft 5 rotate downward in an inverted V shape, which can achieve the purpose of shifting the raw materials downward. In this way, the raw materials in the tank body 1 can be fully fermented and reacted, thereby further improving the fermentation efficiency of the raw materials in the tank body 1.

[0037] Working principle: the motor 4 is started, the first bevel gear 6 is synchronously meshed to drive the second bevel gear 8 to rotate, so that the rotating shaft 5 rotates with the second bevel gear 8, and at the same time, the support plate 12 synchronously drives the supporting pulley 13 to move in the circumferential direction on the control housing 3. When the supporting pulley 13 slides from bottom to top along the arc surface of the arc-shaped protrusion 14, the supporting plate 12 synchronously drives the rotating shaft 5 to move upward. When the supporting pulley 13 slides downward along the vertex of the arc-shaped protrusion 14, the rotating shaft 5 moves downward under the action of inertia, driving the stirring blade 15 to move up and down in the tank body 1;

[0038] At the same time, when the rotating shaft 5 moves upward, the gear 19 rotates clockwise under the meshing transmission of the teeth 21, so that the deflector plates 17 on both sides of the rotating shaft 5 rotate upward to form a V shape, so that when the rotating shaft 5 moves upward, the purpose of shifting the raw materials upward can be achieved. When the rotating shaft 5 moves downward, the gear 19 rotates counterclockwise under the meshing transmission of the teeth 21, so that the deflector plates 17 on both sides of the rotating shaft 5 rotate downward to form an inverted V shape, which can achieve the purpose of shifting the raw materials downward.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
