Description

Technical Field

[0001] The invention relates to the technical field of homogenization, in particular to a variable speed beating homogenization device and a homogenization method for ice cream raw materials. Background Art

[0002] Ice cream raw material beating and homogenizing device is usually used to improve the taste, texture and uniformity and stability of ice crystals of ice cream. By adjusting the speed during the beating process, the solid matter in the raw material can be mixed with the liquid matter more effectively, thereby improving the quality of ice cream.

[0003] Ice cream usually contains ingredients such as milk fat, sugar water, and protein. Emulsifiers can reduce the surface tension between the water phase and the oil phase, so that the oil and water can be mixed more evenly to form a stable emulsion; however, since the water phase and the oil phase are not easy to mix, if the emulsifier is added directly, the emulsifier cannot be mixed well with other raw materials, and it takes a long time to stir to make the various raw materials evenly mixed together, which invisibly increases the production cost. Summary of the invention

[0004] The object of the present invention is to provide a variable speed beating and homogenizing device and a homogenizing method for ice cream raw materials, so as to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the variable speed beating homogenizing device includes a bracket, a mixing tank, a stirring mechanism and a dosing mechanism, the mixing tank is tightly connected to the bracket, the stirring mechanism is tightly connected to the mixing tank, the stirring mechanism is used to homogenize the ice cream raw materials, the dosing mechanism is tightly connected to the mixing tank, the dosing mechanism is connected to the stirring mechanism, and the dosing mechanism is used to add an emulsifier to the ice cream raw materials.

[0006] The bracket provides stable support for the mixing tank. When homogenizing the ice cream raw materials, first add various raw materials into the mixing tank, and then start the stirring mechanism to stir and mix the raw materials. Since the ice cream raw materials contain two components, water phase and oil phase, and the density of the water phase raw materials is large, it tends to be distributed at the bottom of the mixing tank, resulting in stratification of the raw materials. In order to promote the mixing of raw materials with different ingredients, emulsifiers are added through the dosing mechanism to promote mixing. After the raw materials are mixed, the speed of the stirring mechanism is increased to homogenize the raw materials to improve the fineness of the texture of the finished ice cream.

[0007] Furthermore, the stirring mechanism includes a driving motor, a rotating shaft and a blade group. The driving motor is tightly connected to the mixing tank, the output end of the driving motor is transmission-connected to the rotating shaft, the blade group is tightly connected to the rotating shaft, and the blade group is arranged in two upper and lower groups along the rotating shaft. The two groups of blade groups are respectively composed of four stirring blades. A guide component is provided between two adjacent stirring blades. The guide component is used to mix uneven raw materials with emulsifiers. A detection component is also provided on the rotating shaft. The position of the detection component corresponds to the guide component. The detection component is used to detect the uniformity of the raw materials.

[0008] The driving motor is the main power source of the stirring mechanism. During mixing, the driving motor drives the rotating shaft to rotate slowly, thereby driving the stirring blades in the blade group to rotate and mix the raw materials. Since the water phase and oil phase components in the raw materials will be stratified, the distribution of water phase and oil phase components in the raw materials located at the upper and lower blade groups is detected through the detection components at the corresponding positions. The density of the water phase component is relatively large and tends to be distributed near the lower blade group. At this time, the guide component at the same position is started to transport the raw materials containing more water phase to the top, and mix a certain amount of emulsifier during the transportation process, thereby promoting the mixing of the raw materials.

[0009] Furthermore, the dosing mechanism includes a storage tank and a liquid dispensing plate, the storage tank is tightly connected to the mixing tank, a liquid supply pump is provided in the storage tank, the water outlet of the liquid supply pump is connected to the liquid dispensing plate, the liquid dispensing plate is tightly connected to the mixing tank, and the liquid dispensing plate is rotatably connected to the rotating shaft.

[0010] The storage tank is used to store emulsifiers. When the raw materials are mixed, the emulsifier is transported to the liquid mixing plate through the pipeline by the liquid supply pump, and then the emulsifier is transported to the raw materials at the corresponding position through the liquid mixing plate.

[0011] Furthermore, a liquid inlet channel, a first channel, a second channel, an upper liquid outlet and a lower liquid outlet are provided on the rotating shaft. The liquid inlet channel is connected to the inner cavity of the liquid distribution plate, and the outlet of the liquid inlet channel is connected to the upper liquid outlet and the lower liquid outlet respectively. The inlet of the first channel is connected to the upper guide component, the outlet of the first channel is connected to the lower liquid outlet, the inlet of the second channel is connected to the lower guide component, the outlet of the second channel is connected to the upper liquid outlet, and the inlets of the first channel and the second channel are both provided with delivery pumps.

[0012] The flow guide component transfers the unevenly distributed raw materials. The raw materials with more water phase components are guided by the flow guide component located below, and then pumped by the delivery pump, moved upward to the upper liquid outlet through the second flow channel, and mixed with the emulsifier in the liquid inlet flow channel at the upper liquid outlet, and finally flowed out from above the rotating shaft; the raw materials with more oil phase components are guided by the flow guide component located above and pumped by the delivery pump, moved downward to the lower liquid outlet through the first flow channel, and mixed with the emulsifier in the liquid inlet flow channel at the lower liquid outlet, and finally flowed out from below the rotating shaft; that is, the oil phase components distributed above and the water phase components distributed below are transferred through the cooperation of the flow guide component and the flow channel in the rotating shaft, and the emulsifier is added during the transfer process, thereby improving the mixing degree of the raw materials.

[0013] Furthermore, the detection assembly includes a protective shell, a slider, a magnetic rod, an adjustment spring, a coil and a floating block. The protective shell is tightly connected to the rotating shaft, a slide groove is provided inside the protective shell, the slider is slidably connected to the slide groove, the magnetic rod is tightly connected to the slider, one end of the adjustment spring is tightly connected to the inner wall of the slide groove, the other end of the adjustment spring is tightly connected to the bottom end of the slider, the coil is wound around the outside of the slide groove, the coil is located at one end close to the magnetic rod, the coil is externally connected to the detection system, and the floating block is tightly connected to the slider; During detection: the magnetic bar and the coil move relative to each other.

[0014] The protective shell is fixed on the rotating shaft to provide support for the detection component. During the mixing process, the stirring mechanism is in a slow rotation stage. At this time, the liquid impact force on the floating block is negligible. The floating block immersed in the raw material is mainly affected by buoyancy and gravity. The buoyancy of the water phase on the immersed floating block is greater than the buoyancy of the oil phase. That is, when the floating block rotates to a position with more water phase, the buoyancy it receives will increase, thereby pushing the floating block to deflect upward, driving the slider to move upward along the slide slot, and the magnetic rod will also move upward synchronously, thereby generating relative motion with the coil, generating a positive induced current in the coil, and because the more water phase components there are, the greater the buoyancy the floating block receives, and the magnetic rod moves upward. The longer the distance, the greater the forward induced current generated by the coil, that is, the greater the forward induced current generated on the coil detected by the detection system, the more water phase components are distributed here; and when the float rotates to a position with more oil phase, the buoyancy will decrease, the magnetic bar will move downward, and the more oil phase components there are, the smaller the buoyancy received by the float, the longer the distance the magnetic bar moves downward, and the greater the reverse induced current generated by the coil, that is, the greater the reverse induced current generated on the coil detected by the detection system, the more oil phase components are distributed here; that is, through the cooperation between the float, slider, magnetic bar and coil, the distribution of water phase and oil phase components at different positions can be automatically detected.

[0015] Furthermore, the flow guide assembly includes a connecting block, a movable ring, a semicircular cover, an annular electromagnet and a supporting spring, the connecting block is tightly connected to the rotating shaft, the inner cavity of the connecting block located at the top is connected to the first flow channel, the inner cavity of the connecting block located at the bottom is connected to the second flow channel, a guide groove is provided on the connecting block, the movable ring is slidably connected to the guide groove, the semicircular cover is tightly connected to the movable ring, the semicircular cover is slidably connected to the guide groove, the annular electromagnet is tightly connected to the inner wall of the guide groove, one end of the supporting spring is tightly connected to the movable ring, the other end of the supporting spring is tightly connected to the inner wall of the guide groove, a repelling magnet is provided on the end of the movable ring close to the annular electromagnet, and the facing ends of the repelling magnet and the annular electromagnet are magnetic poles of the same name; During diversion: the semicircular cover and the guide groove make relative movement.

[0016] The more distributed the water phase components are, the larger the forward induced current detected by the detection system is; the more distributed the oil phase components are, the larger the reverse induced current detected by the detection system is. That is, the larger the induced current detected by the detection system is, the more uneven the distribution of the raw materials at the corresponding position is, the larger the current transmitted by the control system to the annular electromagnet in the guide assembly at the corresponding position is, the larger the magnetic force generated by the annular electromagnet is, the larger the repulsive force exerted on the repulsive magnet is, the longer the distance the movable ring is offset outward along the guide groove is, the greater the degree of opening of the semicircular cover is, and the more fluid enters the inner cavity of the connecting block, that is, the amount of transfer is automatically controlled according to the uniformity of the raw materials, thereby improving the mixing degree of the raw materials.

[0017] Furthermore, the cross section of the floating block is streamlined.

[0018] The streamlined float can reduce the resistance during rotation and improve the accuracy of detection.

[0019] Furthermore, the upper liquid outlet and the lower liquid outlet are arranged obliquely, and the inclination direction of the upper liquid outlet and the lower liquid outlet is opposite to the rotation direction of the rotating shaft.

[0020] When the transferred raw materials are discharged from the inclined upper and lower liquid outlets, since the inclination direction is opposite to the rotation direction of the rotating shaft, the discharged raw materials will collide with the raw materials rotating in the forward direction with the stirring blades, thereby promoting the mixing of the raw materials.

[0021] Furthermore, the driving motor adopts a variable frequency motor, and the mixing tank is provided with a feed inlet and a discharge port.

[0022] In order to meet the variable speed rotation during the beating process, the driving motor adopts a variable frequency motor. The raw materials are added from the feed port and discharged from the discharge port.

[0023] The homogenization method is: S1: Add the raw materials into the mixing tank through the feed port; S2: Start the driving motor to drive the stirring blade to rotate slowly to mix the raw materials; S3: Through the cooperation of the detection component and the diversion component, transfer and mix the uneven raw materials; S4: The drive motor drives the stirring blades to rotate rapidly, homogenize the mixed raw materials, and the finished product is discharged from the discharge port.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the mutual cooperation of the diversion component and the flow channel in the rotating shaft, transfer the oil-phase component distributed above and the water-phase component distributed below, and add an emulsifier during the transfer process, thereby improving the mixing degree of the raw materials.

[0025] 2. Through the cooperation among the floating block, the sliding block, the magnetic rod and the coil, and using the inconsistent buoyancy generated by the water-phase and oil-phase components on the floating block, automatically detect the distribution of the water-phase and oil-phase components at different positions.

[0026] 3. Through the mutual cooperation of the annular electromagnet and the repelling magnet, by changing the magnitude of the magnetic force of the annular electromagnet, control the opening degree of the semi-circular cover. The more uneven the raw material distribution, the greater the current transmitted by the control system to the annular electromagnet in the corresponding diversion component, the greater the magnetic force generated by the annular electromagnet, the greater the repulsive force received by the repelling magnet, the longer the distance that the movable ring offsets outward along the guiding groove, the greater the opening degree of the semi-circular cover, and the more fluid enters the inner cavity of the connecting block, that is, automatically control the amount of transfer according to the uniformity of the raw materials, thereby improving the mixing degree of the raw materials.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example: Figure 1-Figure 12 As shown, the present invention provides a technical solution of a variable speed beating homogenizing device and a homogenizing method for ice cream raw materials. The variable speed beating homogenizing device includes a bracket 1, a mixing tank 2, a stirring mechanism 3 and a dosing mechanism 4. The mixing tank 2 is tightly connected to the bracket 1, the stirring mechanism 3 is tightly connected to the mixing tank 2, the stirring mechanism 3 is used to homogenize the ice cream raw materials, the dosing mechanism 4 is tightly connected to the mixing tank 2, the dosing mechanism 4 is communicated with the stirring mechanism 3, and the dosing mechanism 4 is used to add an emulsifier to the ice cream raw materials.

[0031] The bracket 1 provides a stable support for the mixing tank 2. When homogenizing the ice cream raw materials, first add various raw materials into the mixing tank 2, and then start the stirring mechanism 3 to stir and mix the raw materials. Since the ice cream raw materials contain two components, namely, water phase and oil phase, and the density of the water phase raw materials is large, they tend to be distributed at the bottom of the mixing tank 2, which causes the raw materials to be stratified. In order to promote the mixing of raw materials with different ingredients, an emulsifier is added through the dosing mechanism 4 to promote mixing. After the raw materials are mixed, the rotation speed of the stirring mechanism 3 is increased to homogenize the raw materials to improve the fineness of the texture of the finished ice cream.

[0032] The stirring mechanism 3 includes a driving motor 31, a rotating shaft 32 and a blade group 33. The driving motor 31 is tightly connected to the mixing tank 2. The output end of the driving motor 31 is transmission-connected to the rotating shaft 32. The blade group 33 is tightly connected to the rotating shaft 32. The blade group 33 is arranged in two upper and lower groups along the rotating shaft 32. The two groups of blade groups 33 are respectively composed of four stirring blades 331. A guide component 34 is provided between two adjacent stirring blades 331. The guide component 34 is used to mix uneven raw materials with emulsifiers. A detection component 35 is also provided on the rotating shaft 32. The position of the detection component 35 corresponds to the guide component 34. The detection component 35 is used to detect the uniformity of the raw materials.

[0033] The driving motor 31 is the main power source of the stirring mechanism 3. During mixing, the driving motor 31 drives the rotating shaft 32 to rotate slowly, thereby driving the stirring blades 331 in the blade group 33 to rotate to mix the raw materials. Since the water phase and oil phase components in the raw materials will be stratified, the distribution of the water phase and oil phase components in the raw materials located at the upper and lower groups of blade groups 33 is detected through the detection components 35 at the corresponding positions. The density of the water phase component is relatively large and tends to be distributed near the lower blade group 33. At this time, the guide component 34 at the same position is started to transport the raw materials containing more water phase to the top, and mix a certain amount of emulsifier during the transportation process, thereby promoting the mixing of the raw materials.

[0034] The dosing mechanism 4 includes a storage tank 41 and a liquid distribution plate 42. The storage tank 41 is tightly connected to the mixing tank 2. A liquid supply pump is arranged in the storage tank 41. The water outlet of the liquid supply pump is connected to the liquid distribution plate 42. The liquid distribution plate 42 is tightly connected to the mixing tank 2. The liquid distribution plate 42 is rotatably connected to the rotating shaft 32.

[0035] The storage tank 41 is used to store the emulsifier. When the raw materials are mixed, the emulsifier is transported to the liquid distribution plate 42 through the pipeline by the liquid supply pump, and then the emulsifier is transported to the raw materials at the corresponding position through the liquid distribution plate 42.

[0036] The rotating shaft 32 is provided with a liquid inlet channel 321, a first channel 322, a second channel 323, an upper liquid outlet 324 and a lower liquid outlet 325. The liquid inlet channel 321 is connected to the inner cavity of the liquid distribution plate 42, and the outlet of the liquid inlet channel 321 is connected to the upper liquid outlet 324 and the lower liquid outlet 325 respectively. The inlet of the first channel 322 is connected to the upper guide component 34, the outlet of the first channel 322 is connected to the lower liquid outlet 325, the inlet of the second channel 323 is connected to the lower guide component 34, the outlet of the second channel 323 is connected to the upper liquid outlet 324, and the inlets of the first channel 322 and the second channel 323 are both provided with a delivery pump 36.

[0037] The diversion component 34 transfers the raw materials with uneven distribution. For those with a relatively high water-phase component, they are guided by the diversion component 34 located below, then pumped by the delivery pump 36, move upward through the second flow channel 323 to the upper liquid outlet 324, and are mixed with the emulsifier in the liquid inlet flow channel 321 at the upper liquid outlet 324, and finally flow out above the rotating shaft 32; for those with a relatively high oil-phase component, they are guided by the diversion component 34 located above and pumped by the delivery pump 36, move downward through the first flow channel 322 to the lower liquid outlet 325, and are mixed with the emulsifier in the liquid inlet flow channel 321 at the lower liquid outlet 325, and finally flow out below the rotating shaft 32; that is, through the mutual cooperation of the diversion component 34 and the flow channels in the rotating shaft 32, the oil-phase components distributed above and the water-phase components distributed below are transferred, and the emulsifier is added during the transfer process, thereby improving the mixing degree of the raw materials.

[0038] The detection component 35 includes a protective shell 351, a slider 352, a magnetic rod 353, an adjusting spring 354, a coil 355 and a floating block 356. The protective shell 351 is fixedly connected to the rotating shaft 32. A chute 3511 is provided inside the protective shell 351. The slider 352 is slidably connected to the chute 3511. The magnetic rod 353 is fixedly connected to the slider 352. One end of the adjusting spring 354 is fixedly connected to the inner wall of the chute 3511, and the other end of the adjusting spring 354 is fixedly connected to the bottom end of the slider 352. The coil 355 is wound around the outside of the chute 3511. The coil 355 is located at one end close to the magnetic rod 353. The coil 355 is externally connected to a detection system. The floating block 356 is fixedly connected to the slider 352; During detection: The magnetic rod 353 and the coil 355 move relative to each other.

[0039] The protective shell 351 is fixed on the rotating shaft 32 to provide support for the detection component 35. Since the stirring mechanism 3 is in a slow rotation stage during the mixing process, the liquid impact force on the floating block 356 is negligible at this time, and the floating block 356 immersed in the raw material is mainly affected by buoyancy and gravity, and the buoyancy of the water phase on the immersed floating block 356 is greater than the buoyancy of the oil phase, that is, when the floating block 356 rotates to a position with more water phase, the buoyancy it receives will increase, thereby pushing the floating block 356 to deflect upward, driving the slider 352 to move upward along the slide groove 3511, and the magnetic rod 353 will also move upward synchronously, thereby generating relative motion with the coil 355, and a positive induced current will be generated in the coil 355. In addition, since the more water phase components there are, the greater the buoyancy on the floating block 356, the magnetic rod 3 The longer the distance that the float 356 moves upward, the greater the forward induced current generated by the coil 355, that is, the greater the forward induced current generated on the coil 355 detected by the detection system, the more the water phase components are distributed here; and when the float 356 rotates to a position with more oil phase, the buoyancy it receives will decrease, the magnetic bar 353 will move downward, and the more oil phase components there are, the smaller the buoyancy the float 356 receives, the longer the distance that the magnetic bar 353 moves downward, and the greater the reverse induced current generated by the coil 355, that is, the greater the reverse induced current generated on the coil 355 detected by the detection system, the more the oil phase components are distributed here; that is, through the cooperation between the float 356, the slider 352, the magnetic bar 353 and the coil 355, the distribution of water phase and oil phase components at different positions can be automatically detected.

[0040] The flow guide assembly 34 includes a connecting block 341, a movable ring 342, a semicircular cover 343, an annular electromagnet 344 and a support spring 345. The connecting block 341 is tightly connected to the rotating shaft 32. The inner cavity of the connecting block 341 located at the top is connected to the first flow channel 322, and the inner cavity of the connecting block 341 located at the bottom is connected to the second flow channel 323. The connecting block 341 is provided with a guide groove 3411, the movable ring 342 is slidably connected to the guide groove 3411, and the semicircular cover 343 is connected to the The movable ring 342 is tightly connected, the semicircular cover 343 is slidably connected to the guide groove 3411, the annular electromagnet 344 is tightly connected to the inner wall of the guide groove 3411, one end of the support spring 345 is tightly connected to the movable ring 342, and the other end of the support spring 345 is tightly connected to the inner wall of the guide groove 3411. A repelling magnet 346 is provided at one end of the movable ring 342 close to the annular electromagnet 344, and the repelling magnet 346 and the facing ends of the annular electromagnet 344 are the same magnetic poles; During flow diversion: the semicircular cover 343 and the guide groove 3411 make relative motion.

[0041] The more distributed the water phase components are, the larger the forward induced current detected by the detection system is; the more distributed the oil phase components are, the larger the reverse induced current detected by the detection system is. That is, the larger the induced current detected by the detection system is, the more uneven the distribution of the raw materials at the corresponding position is, the larger the current transmitted by the control system to the annular electromagnet 344 in the guide assembly 34 at the corresponding position is, the larger the magnetic force generated by the annular electromagnet 344 is, the larger the repulsive force exerted on the repulsive magnet 346 is, the longer the distance that the movable ring 342 is offset outward along the guide groove 3411 is, the greater the degree of opening of the semicircular cover 343 is, and the more fluid enters the inner cavity of the connecting block 341, that is, the amount of transfer is automatically controlled according to the uniformity of the raw materials, thereby improving the mixing degree of the raw materials.

[0042] The cross section of the floating block 356 is streamlined.

[0043] The streamlined float 356 can reduce the resistance encountered during rotation and improve the accuracy of detection.

[0044] The upper liquid outlet 324 and the lower liquid outlet 325 are arranged obliquely, and the inclination direction of the upper liquid outlet 324 and the lower liquid outlet 325 is opposite to the rotation direction of the rotating shaft 32 .

[0045] When the transferred raw materials are discharged from the inclined upper liquid outlet 324 and the lower liquid outlet 325, since the inclination direction is opposite to the rotation direction of the rotating shaft 32, the discharged raw materials will collide with the raw materials rotating in the forward direction with the stirring blade 331, thereby promoting the mixing of the raw materials.

[0046] The driving motor 31 is a variable frequency motor, and the mixing tank 2 is provided with a feed inlet 21 and a discharge outlet 22 .

[0047] In order to meet the variable speed rotation during the beating process, the driving motor 31 adopts a variable frequency motor. The raw materials are added from the feed port 21 and discharged from the discharge port 22.

[0048] The homogenization method is: S1: Add the raw materials into the mixing tank 2 through the feed port 21; S2: starting the driving motor 31 to drive the stirring blade 331 to rotate slowly to mix the raw materials; S3: The uneven raw materials are transferred and mixed by the cooperation of the detection component 35 and the flow guide component 34; S4: the driving motor 31 drives the stirring blade 331 to rotate rapidly to homogenize the mixed raw materials, and the finished product is discharged from the discharge port 22.

[0049] The working principle of the present invention is as follows: first, the stirring mechanism 3 rotates slowly to mix the raw materials, and the distribution of the water phase and oil phase components in the raw materials located at the upper and lower blade groups 33 is detected through the detection component 35 at the corresponding position. The water phase component has a larger density and tends to be distributed near the lower blade group 33. At this time, the guide component 34 at the same position is started to transport the raw materials containing more water phase to the upper part, and a certain amount of emulsifier is mixed in during the transportation process, thereby promoting the mixing of the raw materials. The guide component 34 can automatically control the amount of transfer according to the uniformity of the raw materials, thereby improving the mixing degree of the raw materials; after the raw materials are mixed, the rotation speed of the stirring mechanism 3 is increased to homogenize the raw materials.
