TECHNICAL FIELD
[0001] The present application relates to the field of food processing equipment, in particular to a vacuum mixing device for cheese in-process. BACKGROUND
[0002] Cheese is a fresh or fermented product made from milk, cream, skim milk or partially skimmed milk, buttermilk or mixtures of these raw materials, coagulated by rennet or other coagulants, and part of the whey is removed.
[0003] In the related art, the specific processing procedure of cheese products is as follows: raw material pretreatment, sterilization and cooling, addition of starter, adjustment of acidity, coagulation, stirring, warming and whey removal, maturation and coloration, and hanging. In the stirring process, the cheese curd is kept in a suspended state to prevent it from settling, and the whey inside is gradually removed to form a smooth film on the surface to prevent loss of protein and fat. At the same time, the stirring process must ensure that the skim milk powder, dry powder and malt dextrin are fully mixed to effectively ensure the quality of the cheese product.
[0004] Traditional stirring equipment only stirs cheese curd at a fixed height, which has a limited stirring range and dead corners, and cannot effectively prevent the cheese curd from settling, which leads to clumping and uneven stirring of the cheese curd during stirring, and thus cannot effectively ensure the processing quality of the cheese product. SUMMARY
[0005] The present application provides a vacuum mixing device for cheese in-process, which aims to optimize the cheese stirring equipment so that it can stir cheese curd at different heights during stirring, and the stirring range of the cheese curd can be adaptively adjusted according to the specific processing conditions. This stirring method can effectively ensure the mixing effect of the cheese and prevent the cheese curd from clumping and settling during stirring, thereby effectively ensuring the processing quality of the cheese product.
[0006] The present application provides a vacuum mixing device for cheese in-process, which adopts the following technical solution: A kind of cheese in-product vacuum mixing equipment, including mixer, partition is fixed in the mixer along horizontal direction, the partition divides mixer into the stirring cavity and assembly cavity distributed in upper and lower, the stirring cavity is filled with corresponding cheese product, and stirring vane is additionally provided in the stirring cavity for stirring cheese product, the stirring vane is rotatably installed in the stirring cavity, the stirring vane rotates in the stirring cavity while lifting along vertical direction, and the stirring vane is telescopic along horizontal direction during lifting;The top of the mixer is fastened with driving motor, the bottom of the driving motor is installed with rotating shaft along vertical direction, the rotating shaft extends into the stirring cavity, and is connected with the stirring vane;The stirring vane is divided into primary blade, secondary blade and tertiary blade, the primary blade is hollow, the secondary blade and the tertiary blade are arranged in the primary blade and are telescopic along horizontal direction, and the secondary blade is hollow, the tertiary blade is arranged in the secondary blade and is telescopic along horizontal direction; The rotating shaft is sleeved with driving gear along horizontal direction, the rotating shaft is integrally sleeved with adapter, the adapter is integrally connected with driven gear on the side close to the rotating shaft, the driven gear and the driving gear are meshed and connected, the stirring vane is installed with first driving screw along horizontal direction, the first driving screw penetrates the primary blade, secondary blade and tertiary blade in sequence, and the end of the first driving screw is connected with the adapter and corresponding driven gear, the secondary blade and the tertiary blade are provided with internal thread hole along the length direction and are screwed with the first driving screw; Limiting assembly is arranged between the primary blade and the secondary blade and between the secondary blade and the tertiary blade, for limiting the telescopic of the secondary blade and the tertiary blade along horizontal direction.
[0007] By employing the above technical solution, the mixing blades are used to agitate the cheese products, ensuring thorough mixing of their components. The mixing blades are rotatably mounted within the mixing chamber and can move vertically up and down while rotating, allowing them to agitate cheese products at different heights within the chamber. This ensures the components of the cheese products are fully integrated within the mixer, effectively improving the blending effect and guaranteeing the quality of subsequent cheese product processing. Initially, the mixing blades are located at the top of the mixer, with one end of the secondary blade extending beyond the primary blade and one end of the tertiary blade extending beyond the secondary blade. In this state, the mixing range is at its maximum. As the mixing blades gradually descend towards the bottom of the mixer, the secondary and tertiary blades gradually retract into the primary blade. During this process, the mixing range of the blades gradually decreases, allowing them to adapt to the decreasing space at the bottom of the mixer. As the mixing blades gradually rise, the secondary and tertiary blades gradually extend from the primary blades. During this process, the mixing range of the mixing blades gradually increases, so that the mixing blades can effectively adapt to the gradually increasing space at the top of the mixer.
[0008] Preferably, the limiting component includes a first limiting plate and a second limiting plate. The first limiting plate has an "L" shape, and the second limiting plate has an inverted "L" shape. The first limiting plate is integrally connected to the top of the first-stage blade, and the second limiting plate is integrally connected to the top of the second-stage blade. The first limiting plate and the second limiting plate are used to limit the extension and retraction of the second-stage blade on the first-stage blade.
[0009] By adopting the above technical solution, as the secondary blade gradually extends outward from the primary blade, the secondary blade stops extending outward from the primary blade after the second limiting plate and the first limiting plate are engaged together. The extension of the secondary blade is restricted by the first limiting plate and the second limiting plate, thereby effectively preventing the secondary blade from sliding out of the primary blade's channel and ensuring the stability of the secondary blade sliding on the primary blade.
[0010] Preferably, a cooling box is provided on the top of the mixer, and the cooling box is in communication with the inside of the mixer. The cooling box is used to cool down the cheese products inside the mixer.
[0011] By adopting the above technical solution, the cooling box is filled with cold air, which is used to cool down the inside of the mixer, thereby effectively solving the problem of excessive coagulation of whey protein caused by excessive temperature of cheese products inside the mixer due to prolonged stirring.
[0012] Preferably, a cooling channel is formed in the vertical direction on the top of the mixer, the cooling box is fastened on the top of the cooling channel, the cooling box is kept in communication with the mixer through the cooling channel, a movable plate is slidingly installed in the cooling channel along the length direction of the cooling channel, and a ventilation opening is formed between one end of the movable plate and the cooling channel.
[0013] By using the above technical scheme, the sliding of the movable plate in the cooling channel controls the closing of the ventilation opening, when the ventilation opening is opened, the cooling air in the cooling box fills the mixer through the cooling channel and the ventilation opening to complete the cooling of the cheese product in the mixer.
[0014] Preferably, an inner threaded hole is formed in the length direction of the movable plate, and a second driving screw is inserted into the inner threaded hole, and the second driving screw and the rotating shaft are connected through a horizontally arranged transmission belt.
[0015] By using the above technical scheme, the second driving screw is driven to rotate by the transmission belt during the rotation of the rotating shaft, and the second driving screw drives the movable plate to slide in the cooling channel during the rotation.
[0016] Preferably, the movable plate is in the overall structure of a right trapezoid, the bottom is a horizontal plane, the other side is a wedge-shaped surface, and the ventilation opening is formed between the wedge-shaped surface and the side wall of the cooling channel.
[0017] By using the above technical scheme, when the mixer does not need to be cooled in the initial state, the horizontal plane of the movable plate is flush with the bottom of the cooling channel, the horizontal plane of the movable plate is used to seal the cooling channel, thereby effectively preventing the leakage of the cooling air in the cooling box. When the mixer needs to be cooled, the second driving screw drives the movable plate to slide downward, and in this process, the ventilation opening is gradually opened, thereby completing the cooling of the mixer.
[0018] Because the side wall of the movable plate is a wedge-shaped surface, the more the distance of the movable plate sliding out of the cooling channel, the larger the opening range of the ventilation opening. The purpose of this is that as the rotating shaft rotates, the longer the stirring time of the stirring blade on the cheese product, the more cooling air the cheese product needs to cool. By arranging the ventilation opening between the wedge-shaped surface of the movable plate and the side wall of the cooling channel, the longer the stirring time of the stirring blade, the more the distance of the movable plate extending out of the cooling channel, the larger the opening range of the ventilation opening, thereby the better the cooling effect of the cheese product in the mixer, thereby forming a benign cycle and effectively guaranteeing the quality of the cheese product in the processing process.
[0019] Preferably, the bottom of the driving motor is connected with a first gear through a rotating shaft arranged vertically, the first gear is arranged horizontally, the top of the rotating shaft is integrally connected with a second gear in the horizontal direction, the second gear is arranged horizontally, and the first gear and the second gear are connected in meshing.
[0020] By adopting the above technical scheme, in the process that the driving motor drives the first gear to rotate, the first gear synchronously drives the second gear and the rotating shaft to rotate.
[0021] Preferably, half of the first gear is a toothed part, and the other half is a smooth part.
[0022] By adopting the above technical scheme, when the toothed part of the first gear rotates to the second gear and meshes with the second gear, the first gear synchronously drives the second gear to rotate; when the smooth part of the first gear rotates to the second gear, the first gear and the second gear are in a disconnected meshing state, in which state, the first gear cannot drive the second gear to rotate, and at this time, the rotating shaft cannot rotate, and the stirring blade stops stirring the cheese product.
[0023] The purpose of this is to realize the intermittent stirring of the stirring blade on the cheese product in the mixer, thereby effectively preventing the stirring blade from stirring the cheese product for too long, causing the viscosity of the cheese product to drop sharply due to thixotropy, and effectively preventing overheating caused by stirring for too long from causing abnormal viscosity.
[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The stirring blade stirs the cheese product, allowing the ingredients in the cheese product to be fully mixed. The stirring blade is installed in the stirring chamber and can be raised and lowered in the vertical direction while rotating in the stirring chamber, thereby allowing the stirring blade to stir the cheese product at different heights in the stirring chamber, thereby facilitating the full fusion of the ingredients in the cheese product in the mixer, effectively improving the fusion effect of the cheese product in the mixer, and effectively ensuring the quality of subsequent cheese product processing. In the initial state, the stirring blade is located at the top of the mixer, at which time one end of the second blade extends beyond the first blade, and one end of the third blade extends beyond the second blade. In this state, the stirring range of the stirring blade is the largest; as the stirring blade gradually descends towards the bottom of the mixer, the second blade and the third blade gradually retract into the first blade. During this process, the stirring range of the stirring blade gradually decreases to allow the stirring blade to effectively adapt to the gradually decreasing space range at the bottom of the mixer. As the stirring blade gradually rises, the second blade and the third blade gradually extend from the first blade. During this process, the stirring range of the stirring blade gradually increases to allow the stirring blade to effectively adapt to the gradually increasing space range at the top of the mixer. 2. The side wall of the movable plate is wedge-shaped, so that the opening range of the air vent is larger as the distance of the movable plate extending out of the cooling channel is longer. The purpose is that the longer the stirring blade stirs the cheese product, the more cooling air is needed. The air vent is arranged between the wedge-shaped surface of the movable plate and the side wall of the cooling channel. The longer the stirring blade stirs the cheese product, the more distance the movable plate extends out of the cooling channel, and the larger the opening range of the air vent, so that the cooling effect of the cheese product in the mixer is better, and a virtuous cycle is formed, so that the quality of the cheese product in the processing process can be effectively guaranteed. 3. The intermittent stirring of the stirring blade to the cheese product in the mixer can effectively prevent the stirring blade from stirring the cheese product for too long, causing the viscosity of the cheese product to drop sharply due to thixotropy, and can also effectively prevent overheating caused by stirring for too long from causing abnormal viscosity.

Stirring blade 5 is rotatably installed in stirring chamber 3, and stirring blade 5 can be lifted along the vertical direction while rotating in stirring chamber 3, so that stirring blade 5 can stir cheese product of different heights in stirring chamber 3, thereby facilitating to ensure that the ingredients in cheese product can be fully mixed in mixer 1, thereby effectively improving the mixing effect of cheese product in mixer 1, so as to effectively ensure the quality of subsequent cheese product processing.
[0029] During the lifting of stirring blade 5 in stirring chamber 3 along the vertical direction, stirring blade 5 can be synchronously telescoped in the horizontal direction, so that the stirring range of stirring blade 5 can be synchronously adjusted during lifting, thereby enabling the stirring range of stirring blade 5 to be adaptively adjusted according to the space inside mixer 1, effectively improving the adaptability of stirring blade 5, so that stirring blade 5 can also be lifted along the vertical direction in mixer 1 of different shapes and different space sizes.
[0030] Specifically, two stirring blades 5 are provided, and the two stirring blades 5 are symmetrically distributed in stirring chamber 3. Since the bottom of mixer 1 is conical, the space is smaller as it is closer to the bottom.

[0036] The rotating shaft 7 is a telescopic shaft, which can be telescoped with the lifting of the stirring blade 5 in the process of lifting of the stirring blade 5, thereby effectively preventing the lifting of the stirring blade 5 from being hindered by the rotating shaft 7.
[0037] Specifically, referring to Figure 2 and Figure 3 , the stirring blade 5 is divided into a first blade 51, a second blade 52 and a third blade 53, the first blade 51 is hollow, the second blade 52 and the third blade 53 are arranged in the first blade 51 in the horizontal direction, the second blade 52 is hollow, and the third blade 53 is arranged in the second blade 52 in the horizontal direction. The first blade 51 is provided with a channel for the second blade 52 and the third blade 53 to slide in the length direction of the first blade 51, and the second blade 52 is provided with a channel for the third blade 53 to slide in the length direction of the second blade 52.
[0038] In the initial state, the stirring blade 5 is located at the top of the mixer 1, at this time, one end of the secondary blade 52 extends out of the primary blade 51, and one end of the tertiary blade 53 extends out of the secondary blade 52, in this state, the stirring range of the stirring blade 5 is the largest; as the stirring blade 5 gradually descends towards the bottom of the mixer 1, the secondary blade 52 and the tertiary blade 53 gradually retract into the primary blade 51, during this process, the stirring range of the stirring blade 5 gradually decreases, so that the stirring blade 5 can effectively adapt to the gradually decreasing space range at the bottom of the mixer 1. As the stirring blade 5 gradually rises, the secondary blade 52 and the tertiary blade 53 gradually extend out of the primary blade 51, during this process, the stirring range of the stirring blade 5 gradually increases, so that the stirring blade 5 can effectively adapt to the gradually increasing space range at the top of the mixer 1.
[0039] Specifically, referring to Figure 2 and Figure 3 , the rotating shaft 7 is hollow inside, and a driving gear 8 is mounted inside the rotating shaft 7 in the horizontal direction, and a corresponding bearing is mounted between the driving gear 8 and the rotating shaft 7, so that the driving gear 8 does not rotate synchronously with the rotating shaft 7 during rotation. At the same time, a adapter 9 is integrally sleeved on the rotating shaft 7, the adapter 9 is in the shape of a "n" structure, and a driven gear 10 is integrally connected to the side of the adapter 9 close to the rotating shaft 7, and the driven gear 10 is meshed and connected with the driving gear 8. A first driving screw 11 is mounted on the stirring blade 5 in the horizontal direction, the first driving screw 11 penetrates the primary blade 51, the secondary blade 52 and the tertiary blade 53 in sequence, and the end of the first driving screw 11 penetrates the adapter 9 and is connected with the corresponding driven gear 10. The secondary blade 52 and the tertiary blade 53 are provided with internal threaded holes for screwing with the first driving screw 11 along the length direction, and the first driving screw 11 drives the secondary blade 52 and the tertiary blade 53 to stretch and retract in the horizontal direction during rotation.
[0040] In specific use, the rotating shaft 7 drives the adapter 9 to rotate synchronously during rotation, the adapter 9 drives the first driving screw 11 and the driven gear 10 to rotate synchronously during rotation, the driven gear 10 meshes with the driving gear 8 during rotation, and then drives the first driving screw 11 to rotate axially by using the driven gear 10, the first driving screw 11 drives the secondary blade 52 and the tertiary blade 53 to stretch and retract in the horizontal direction during rotation, thereby adjusting the stirring range of the stirring blade 5.
[0041] Further, a limiting assembly is arranged between the first blade 51 and the second blade 52 and between the second blade 52 and the third blade 53, and is used to limit the expansion of the second blade 52 and the third blade 53 in the horizontal direction, so as to effectively guarantee the stability of the second blade 52 and the third blade 53 during the expansion. In the embodiment, the limiting assembly limits the second blade 52 and the third blade 53 in the same way, and the second blade 52 is taken as an example for description.
[0042] Specifically, referring to Figure 2 , Figure 3 and Figure 4 , the limiting assembly comprises a first limiting plate 12 and a second limiting plate 13. The first limiting plate 12 is in an "L" shape structure, and the second limiting plate 13 is in an inverted "L" shape structure. The first limiting plate 12 is integrally connected to the top of the first blade 51, and the second limiting plate 13 is integrally connected to the top of the second blade 52. When the second limiting plate 13 and the first limiting plate 12 are clamped together, the second blade 52 stops continuing to extend out of the first blade 51 as the second blade 52 gradually extends out of the first blade 51. The first limiting plate 12 and the second limiting plate 13 limit the extension of the second blade 52, thereby effectively preventing the second blade 52 from sliding out of the channel of the first blade 51, and effectively guaranteeing the stability of the second blade 52 sliding on the first blade 51.
[0043] Further, referring to Figure 1 and Figure 2 , a cooling box 14 is additionally arranged on the top of the mixer 1. The cooling box 14 is in communication with the mixer 1, and the cooling box 14 is filled with corresponding cold air. The cold air is used to cool the mixer 1, thereby effectively solving the problem of excessive coagulation of whey protein caused by the high temperature of the cheese product in the mixer 1 due to long-time stirring.
[0044] Specifically, referring to Figure 2 and Figure 5 , a cooling channel 15 is formed in the vertical direction on the top of the mixer 1. The cooling box 14 is fastened to the top of the cooling channel 15 by corresponding fastening bolts. The cooling box 14 is in communication with the mixer 1 through the cooling channel 15. A movable plate 16 is slidably installed in the cooling channel 15 along the length direction of the cooling channel 15. An air vent 17 is formed between one end of the movable plate 16 and the cooling channel 15. The closure of the air vent 17 is controlled by the sliding of the movable plate 16 in the cooling channel 15. When the air vent 17 is opened, the cold air in the cooling box 14 is filled into the mixer 1 through the cooling channel 15 and the air vent 17 to cool and lower the temperature of the cheese product in the mixer 1.
[0045] Specifically, referring to Figure 2 and Figure 5, the movable plate 16 is provided with an internally threaded hole along the length direction thereof, and the second driving screw 18 is inserted into the internally threaded hole, and the second driving screw 18 is connected with the rotating shaft 7 through the horizontally arranged transmission belt 19. The rotating shaft 7 drives the second driving screw 18 to rotate through the transmission belt 19 during rotation, and the second driving screw 18 drives the movable plate 16 to slide in the cooling channel 15 during rotation.
[0046] The side wall of the cooling channel 15 is provided with a sliding groove along the length direction thereof, and the side close to the sliding side of the movable plate 16 is integrally connected with a sliding block, so that the stability of the movable plate 16 during sliding in the cooling channel 15 is effectively ensured by the sliding groove and the sliding block.
[0047] Specifically, referring to Figure 2 and Figure 5 , in the embodiment, the movable plate 16 has a straight trapezoidal structure as a whole, the bottom thereof is a horizontal plane 20, the other side is a wedge-shaped plane 21, and the air vent 17 is formed between the wedge-shaped plane 21 and the side wall of the cooling channel 15. In the initial state, when the mixer 1 does not need to be cooled, the horizontal plane 20 of the movable plate 16 is flush with the bottom of the cooling channel 15, the horizontal plane 20 of the movable plate 16 is used to seal the cooling channel 15, thereby effectively preventing the leakage of cold air in the cooling box 14. When the mixer 1 needs to be cooled, the second driving screw 18 drives the movable plate 16 to slide downward, and in this process, the air vent 17 is gradually opened, thereby completing the cooling of the mixer 1.
[0048] Since the side wall of the movable plate 16 is the wedge-shaped plane 21, the range of the air vent 17 opening becomes larger as the distance of the movable plate 16 sliding out of the cooling channel 15 becomes larger. The purpose of this is that as the rotating shaft 7 rotates, the longer the stirring time of the stirring blade 5, the more cooling air the cheese product needs. The air vent 17 is arranged between the wedge-shaped plane 21 of the movable plate 16 and the side wall of the cooling channel 15, the longer the stirring time of the stirring blade 5, the larger the distance of the movable plate 16 extending out of the cooling channel 15, and the larger the range of the air vent 17 opening, thereby the better the cooling effect of the cheese product in the mixer 1, thereby forming a benign cycle and closing, thereby effectively ensuring the quality of the cheese product during processing.
[0049] Further, referring to Figure 1 and Figure 2 , the bottom of the driving motor 6 is connected with a first gear 22 through a vertically arranged rotating shaft, and the first gear 22 is horizontally arranged. The top of the rotating shaft 7 is integrally connected with a second gear 23 along the horizontal direction, and the second gear 23 is horizontally arranged, and the first gear 22 and the second gear 23 are engaged and connected. During the rotation of the driving motor 6 driving the first gear 22, the first gear 22 synchronously drives the second gear 23 and the rotating shaft 7 to rotate.
[0050] Specifically, one half of the first gear 22 is a toothed portion, and the other half is a smooth portion. When the toothed portion of the first gear 22 rotates to the second gear 23 and engages with the second gear 23, the first gear 22 drives the second gear 23 to rotate synchronously. When the smooth portion of the first gear 22 rotates to the second gear 23, the first gear 22 and the second gear 23 are in a disengaged state, in which the first gear 22 cannot drive the second gear 23 to rotate. At this time, the rotating shaft 7 cannot rotate, and the stirring blade 5 stops stirring the cheese product.
[0051] The purpose of this is to achieve intermittent stirring of the cheese product in the mixer 1 by the stirring blade 5, thereby effectively preventing the cheese product from being stirred for too long, causing the viscosity of the cheese product to drop sharply due to thixotropy, and preventing overheating caused by stirring for too long from causing abnormal viscosity.
[0052] The implementation principle of the cheese product vacuum mixing device according to the embodiment is as follows: During the vertical lifting of the stirring blade 5 in the stirring cavity 3, the stirring blade 5 can synchronously stretch and contract in the horizontal direction, which enables the size of the stirring range of the stirring blade 5 to be adjusted synchronously during the lifting process, thereby enabling the size of the stirring range of the stirring blade 5 to be adaptively adjusted according to the space inside the mixer 1, effectively improving the adaptability of the stirring blade 5, and enabling the stirring blade 5 to also be lifted in the vertical direction in mixers 1 of different shapes and different space sizes.
[0053] Specifically, the stirring blade 5 is provided in two, and the two stirring blades 5 are symmetrically distributed in the stirring cavity 3. Since the bottom of the mixer 1 is conical, the space at the bottom is smaller. When the two stirring blades 5 gradually descend, the two stirring blades 5 gradually contract towards each other, and the stirring range between the two stirring blades 5 gradually decreases during this process, thereby enabling the two stirring blades 5 to adapt to the gradually decreasing space range at the bottom of the mixer 1. When the two stirring blades 5 gradually ascend, the two stirring blades 5 gradually stretch away from each other, and the stirring range between the two stirring blades 5 gradually increases during this process, thereby enabling the two stirring blades 5 to adapt to the gradually increasing space range at the top of the mixer 1.
[0054] This arrangement optimizes the structure of the stirring blade 5, enabling it to also satisfy the requirement of stirring cheese products of different heights in a conical mixer 1, thereby effectively guaranteeing the mixing effect of the cheese product, and effectively improving the subsequent processing quality of the cheese product.
[0055] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
