Description

Technical Field

[0001] This invention relates to the field of cosmetic emulsification technology, specifically to an automatic monitoring emulsification device for dispersed phase in cosmetic production. Background Technology

[0002] As an emerging industry in recent years, cosmetics have made great progress with the continuous development of automation technology, and production efficiency has also increased significantly.

[0003] In the production of cosmetics, an emulsification reaction is generally required. This involves adding surfactants to uniformly mix the oil and water phases, forming an emulsion. Emulsions are typically opaque media, and the oil phase, acting as the dispersed phase, cannot be monitored for dispersion quality when dispersed in water. If an incompletely dispersed emulsion is fed into subsequent processing steps, it can easily affect the final molding quality.

[0004] In addition, conventional emulsification equipment, such as emulsification by stirring, has fewer shearing interfaces, which affects emulsification efficiency, extends the emulsification processing time, and increases the production cost for enterprises. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic monitoring emulsification device for dispersed phase in cosmetic production, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An automatic monitoring emulsification device for dispersed phase in cosmetic production includes a tank, a drive unit, a circulation unit, and a transfer box. The drive unit is connected to the tank, the tank and the circulation unit are connected by a pipeline, the circulation unit and the transfer box are connected by a pipeline, one side of the transfer box is connected to the tank by a pipeline, and the tank is provided with an emulsification chamber. The drive unit includes a drive motor and a stirring paddle. The drive motor is fastened to the tank, the output end of the drive motor is drivenly connected to the stirring paddle, the stirring paddle is located in the emulsification chamber, and the upper and lower ends of the stirring paddle are rotatably connected to the emulsification chamber, respectively.

[0008] The tank provides the mounting base for installing other devices. The drive unit serves as the power source, providing shearing power to emulsify the oil and water phases. The oil phase acts as the dispersed phase, dispersed within the water phase. The liquid in the emulsification chamber is externally circulated through a circulation device to improve emulsification efficiency. A transfer box provides a monitoring space to monitor the dispersed phase in the circulating liquid, preventing incompletely dispersed oil phase from entering subsequent processing and affecting emulsification quality. The drive motor serves as the power source, driving the agitator to rotate on a fixed axis to stir the two phases. The upper and lower supports are located at the ends of the emulsification chamber to improve emulsification stability.

[0009] Furthermore, the circulation device includes a circulation pump, the circulation pump inlet is connected to the emulsification chamber pipeline, the circulation pump outlet is connected to the transfer box pipeline, and a shut-off valve is provided on the pipeline connecting the transfer box and the tank body.

[0010] The drive unit also includes a transmission assembly, which is connected to the stirring paddle. The stirring paddle includes a paddle shaft, main blades, auxiliary blades, and a collar. The collar is rotatably connected to the paddle shaft. The collar has several lower connecting rods along the circumference. Each lower connecting rod has several auxiliary blades on its upper side. The paddle shaft has several upper connecting rods along the circumference. Each upper connecting rod has several main blades on its lower side. The paddle shaft has several transmission cavities along the vertical direction. The transmission assembly is placed in the transmission cavity. The transmission assembly is connected to the auxiliary blades.

[0011] During emulsification: the auxiliary blades and the main blades rotate in opposite directions.

[0012] The liquid in the emulsification chamber is externally circulated by a circulating pump, thereby improving the efficiency of laminar flow between the upper and lower phases. The inlet of the circulating pump is located at the lower end of the emulsification chamber, and the pumped liquid is sent to a transfer tank. After a certain period of circulation, the dispersed phase of the circulating liquid is monitored. If a dispersed phase is still present, it is reintroduced into the emulsification chamber through a pipeline for emulsification. At this time, the shut-off valve is in the open state. If no dispersed phase is present, the shut-off valve is in the closed state. The emulsion is then transported to the subsequent processing station through the transfer tank to improve emulsification efficiency. By setting up a transmission component, the torque output of the propeller shaft is converted and output in the form of reverse torque. The lower connecting rod drives the auxiliary blades to rotate in the reverse direction. At this time, the propeller shaft drives the main blades to rotate in the forward direction through the upper connecting rod. The main blades and auxiliary blades rotate in different directions and form a pair. During the reverse rotation, a shear gap is formed between the main blades and auxiliary blades. The two-phase fluid is emulsified by shear force. By setting up multiple sets of main blades and auxiliary blades, the emulsification efficiency is improved.

[0013] Furthermore, the transmission assembly includes a drive wheel and a guide wheel. The drive wheel is connected to the propeller shaft. The outer ring of the drive wheel is provided with several planetary gears. The drive wheel and the planetary gears mesh with each other. The planetary gears mesh with the inner ring of the guide wheel. The planetary gears extend upwards and are provided with a folding rod. The lower end of the folding rod is rotatably connected to the planetary gear. The output end of the folding rod is fastened to a collar. The outer side of the guide wheel is provided with several brackets. The ends of the brackets away from the guide wheel are fastened to the wall of the emulsification chamber. The outer side of the transmission chamber is provided with a mounting groove. The collar is rotatably connected to the mounting groove.

[0014] The driving wheel, serving as the input wheel, is mounted on the propeller shaft and has teeth on its outer ring. The planetary gears, serving as the output wheels, mesh externally with the driving wheel. The driving wheel drives the planetary gears to rotate in the opposite direction. The inner ring of the guide wheel guides the planetary gears' rotation. When the planetary gears rotate, the guide wheel, fixed to the emulsification chamber wall by a bracket, causes the planetary gears to revolve along the guide wheel's centerline. The direction of this revolution is the same as the direction of rotation, which in turn drives the collar to rotate via a folding rod. The collar's rotation axis coincides with the planetary gear's revolution axis. The lower end of the folding rod is inserted into the planetary gear for fixed-axis rotation, while the upper end is securely connected to the collar. This causes the collar to drive the auxiliary blades to rotate in the opposite direction via the lower bracket, improving the shearing emulsification efficiency between the main and auxiliary blades. The collar is guided to rotate through the mounting groove, which seals the groove and prevents emulsion from entering the transmission chamber through the mounting groove.

[0015] Furthermore, the main blade has a top arc on its outer side and a shear groove on its inner side, with the centers of the top arc and the shear groove being collinear.

[0016] The main blades are arc-shaped on the outside and flat on the inside. When the main blades rotate, the liquid flows through the inside and outside of the main blades at different speeds. The liquid on the outside flows faster and has lower pressure, while the liquid on the inside flows slower and has higher pressure, which pushes the liquid on the inside to flow outward, improving the efficiency of internal and external displacement. Shear grooves are set on the inside of the auxiliary blades and are arranged concentrically with the top arc to prevent motion interference and improve the smoothness of shear flow, thereby ensuring emulsification efficiency.

[0017] Furthermore, the number of auxiliary blades on the lower connecting rod is one less than the number of main blades on the adjacent upper connecting rod, and there is a shear gap between the outermost main blade of the upper connecting rod and the wall of the emulsion cavity.

[0018] An upper connecting rod and a lower connecting rod constitute a shear group. Each shear group has one more main blade than auxiliary blade. The outermost main blade and the emulsion cavity wall form a shear flow.

[0019] Furthermore, the circulation device also includes a monitoring component. The transfer box is provided with a circulation chamber, and the circulation pump and the circulation chamber are connected by a pipeline. The monitoring component includes a float and an induction coil. There are several floats, and several floats extend upward with guide rods. The guide rods are made of magnetic material. Several detection slots are provided on the upper side of the circulation chamber. The guide rods are inserted into the detection slots, and the induction coils are placed in the detection slots. The floats are provided with pressure-sensing slots, and the openings of the pressure-sensing slots are set downward.

[0020] The dispersed phase of the circulating liquid is detected by a monitoring component. After one cycle of emulsification is completed, the circulating pump pumps the emulsion into the circulation chamber in stages. Multiple floats are sequentially attached and can slide relative to each other. Due to the high viscosity and surface tension of the emulsion, it cannot penetrate through the gaps between adjacent floats. The circulation chamber has multiple inlets facing the pressure-sensing grooves of the floats. During liquid injection, the pressure-sensing grooves are filled first. As the liquid is injected, all floats rise at a uniform speed. When they float to a fixed height, no more emulsion is injected. If a dispersed phase exists in the emulsion at this time, due to the lower density of the dispersed phase, it will rise to the surface. During the floating process, the surrounding emulsion simultaneously fills the area to which it floats, ensuring that all floats remain at the same height. When the dispersed phase floats to the pressure-sensitive tank and passes over the emulsion, it rises to the top layer. Since the pressure-sensitive tank is a downward-opening groove, the dispersed phase, after entering this pressure-sensitive tank, will not flow to other pressure-sensitive tanks. Under the action of buoyancy, it pushes the float here to move upward, and drives the guide rod to move upward. The induction coil cuts the magnetic field lines, generating an induced current and forming a detection circuit. That is, when the current of several detection circuits produces a difference, it indicates that there is a dispersed phase in the circulation chamber at this time, and the emulsification is incomplete. It needs to be sent into the emulsification chamber for further emulsification.

[0021] As an optimization, a circulation channel is provided on one side of the transfer box, which is connected to the shut-off valve pipeline. Several induction coils are electrically connected to the shut-off valve. The shut-off valve can be powered by an external power source. Based on the current value generated by the detection circuit, it detects whether the dispersed phase is completely emulsified. If the emulsification is incomplete, it controls the shut-off valve to be in the open state.

[0022] As an optimization, the transfer box is equipped with a discharge channel, the height of which is higher than that of the circulation channel. This height difference ensures that when emulsification is complete, the shut-off valve is in the closed state, allowing the emulsion to be sent through the discharge channel to subsequent processing steps, preventing recirculation and improving emulsification efficiency.

[0023] As an optimization, the float is equipped with a balancing chamber. The balancing chamber on the float is a sealed chamber used to balance the weight of the float, so that the buoyancy generated by the dispersed phase can push the float upward, thereby improving the detection accuracy of the dispersed phase.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: When the planetary gear rotates, the guide wheel is fixed to the wall of the emulsification chamber by the bracket, causing the planetary gear to revolve around the center line of the guide wheel. The direction of the revolution is the same as the direction of the rotation, thereby driving the collar to rotate through the folding rod. The axis of rotation of the collar coincides with the axis of revolution of the planetary gear. The lower end of the folding rod is inserted into the planetary gear to rotate on a fixed axis, and the upper end is tightly connected to the collar, causing the collar to drive the auxiliary blade to rotate in the opposite direction through the lower bracket, thereby improving the shearing emulsification efficiency between the main blade and the auxiliary blade. When the main blade is rotating, the liquid flows through the inner and outer sides of the main blade in a differential flow pattern. The outer side has a faster flow speed and lower pressure, while the inner side has a slower flow speed and higher pressure, pushing the inner liquid to flow outward, thereby improving the internal and external displacement efficiency. A shearing groove is set on the inner side of the auxiliary blade and is arranged concentrically with the top arc. To prevent motion interference and improve the smoothness of shear flow, thus ensuring emulsification efficiency; once the float reaches a fixed height, no more emulsion is injected. If a dispersed phase exists in the emulsion at this time, due to the low density of the dispersed phase, the surrounding emulsion fills the area to which it floats during the floating process, ensuring that all floats remain at the same height. When the dispersed phase floats to the pressure-sensitive tank and passes over the emulsion, it floats to the top layer. Since the pressure-sensitive tank is a downward-opening groove, the dispersed phase will not flow to other pressure-sensitive tanks after entering this tank. Under the action of buoyancy, it pushes the float here to move upward and drives the guide rod to move upward. The induction coil cuts the magnetic field lines, generating an induced current and forming a detection circuit. That is, when the current of several detection circuits produces a difference, it indicates that there is a dispersed phase in the circulation chamber at this time, and the emulsification is incomplete. It needs to be sent into the emulsification chamber for further emulsification. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The present invention provides the following technical solution:

[0036] like Figures 1-3 As shown, an automatic monitoring emulsification device for dispersed phase in cosmetic production includes a tank 1, a drive unit 2, a circulation unit 3, and a transfer box 4. The drive unit 2 is connected to the tank 1, the tank 1 is connected to the circulation unit 3 by a pipeline, the circulation unit 3 is connected to the transfer box 4 by a pipeline, one side of the transfer box 4 is connected to the tank 1 by a pipeline, the tank 1 is provided with an emulsification chamber 11, the drive unit 2 includes a drive motor 21 and a stirring paddle 22, the drive motor 21 is fastened to the tank 1, the output end of the drive motor 21 is connected to the stirring paddle 22 for transmission, the stirring paddle 22 is located in the emulsification chamber 11, and the upper and lower ends of the stirring paddle 22 are rotatably connected to the emulsification chamber 11 respectively.

[0037] Tank 1 provides an installation foundation for installing other devices. Drive unit 2 serves as a power source, providing shearing power to emulsify the oil and water phases. The oil phase serves as the dispersed phase, dispersed in the water phase. The liquid in the emulsification chamber 11 is externally circulated through circulation device 3 to improve emulsification efficiency. Transfer box 4 provides a monitoring space to monitor the dispersed phase in the circulating liquid, preventing incompletely dispersed oil phase from entering subsequent processing and affecting emulsification quality. Drive motor 21 serves as a power source, driving the stirring paddle 22 to rotate on a fixed axis to stir the two phases of liquid. The upper and lower ends are supported at the ends of the emulsification chamber 11 to improve emulsification stability.

[0038] like Figures 2-5 As shown, the circulation device 3 includes a circulation pump 31, the inlet of the circulation pump 31 is connected to the emulsification chamber 11 by a pipeline, the outlet of the circulation pump 31 is connected to the transfer box 4 by a pipeline, and a shut-off valve 5 is provided on the pipeline connecting the transfer box 4 and the tank 1.

[0039] The drive device 2 also includes a transmission assembly 23, which is connected to the stirring paddle 22. The stirring paddle 22 includes a paddle shaft 221, main blades 222, auxiliary blades 223, and a collar 224. The collar 224 is rotatably connected to the paddle shaft 221. The collar 224 is provided with several lower connecting rods along the circumference. Each lower connecting rod is provided with several auxiliary blades 223 on its upper side. The paddle shaft 221 is provided with several upper connecting rods along the circumference. Each upper connecting rod is provided with several main blades 222 on its lower side. The paddle shaft 221 is provided with several transmission cavities 2211 along the vertical direction. The transmission assembly 23 is placed in the transmission cavity 2211. The transmission assembly 23 is connected to the auxiliary blades 223.

[0040] During emulsification: the auxiliary blade 223 and the main blade 222 rotate in opposite directions.

[0041] The liquid in the emulsification chamber 11 is externally circulated by a circulating pump 31, thereby improving the laminar flow efficiency of the liquid. The inlet of the circulating pump 31 is located at the lower end of the emulsification chamber 11, and the pumped liquid is sent to the transfer tank 4. After a certain period of circulation, the dispersed phase of the circulating liquid is monitored. If a dispersed phase still exists, it is reintroduced into the emulsification chamber 11 through a pipeline for emulsification. At this time, the shut-off valve 5 is in the open state. If no dispersed phase exists, the shut-off valve 5 is in the closed state, and the emulsion is transported to the subsequent processing station through the transfer tank 4 to improve the emulsification efficiency. This is achieved by setting up a transmission group. Component 23 converts the torque output from propeller shaft 221 and outputs it in the form of reverse torque. It drives the auxiliary blade 223 to rotate in the reverse direction through the lower connecting rod. At this time, propeller shaft 221 drives the main blade 222 to rotate in the forward direction through the upper connecting rod. The main blade 222 and the auxiliary blade 223 rotate in different directions and form a pair of main blades 222 and auxiliary blades 223. During the reverse rotation, a shear gap is formed between the main blade 222 and the auxiliary blade 223. The two-phase fluid is emulsified by shear force. By setting multiple sets of main blades 222 and auxiliary blades 223, the emulsification efficiency is improved.

[0042] like Figures 4-5 As shown, the transmission assembly 23 includes a drive wheel 231 and a guide wheel 233. The drive wheel 231 is connected to the propeller shaft 221. The outer ring of the drive wheel 231 is provided with several planetary gears 232. The drive wheel 231 and the planetary gears 232 mesh with each other. The planetary gears 232 mesh with the inner ring of the guide wheel 233. The planetary gears 232 extend upwards and are provided with a folding rod 235. The lower end of the folding rod 235 is rotatably connected to the planetary gears 232. The output end of the folding rod 235 is fastened to the collar 224. The outer side of the guide wheel 233 is provided with several brackets 234. The end of the brackets 234 away from the guide wheel 233 is fastened to the wall of the emulsification chamber 11. The outer side of the transmission chamber 2211 is provided with a mounting groove 2212. The collar 224 is rotatably connected to the mounting groove 2212.

[0043] The driving wheel 231 is the input wheel, mounted on the propeller shaft 221, with a toothed outer ring. The planetary gear 232 is the output wheel, meshing externally with the driving wheel 231. The driving wheel 231 drives the planetary gear 232 to rotate in the opposite direction. The inner ring of the guide wheel 233 guides the rotation of the planetary gear 232. When the planetary gear 232 rotates, the guide wheel 233 is fixed to the wall of the emulsification chamber 11 by the bracket 234, causing the planetary gear 232 to revolve around the center line of the guide wheel 233. The direction of the revolution is the same as the direction of the rotation, thereby driving the collar 224 to rotate through the lever 235. The rotating axis of the collar 224 coincides with the revolution axis of the planetary gear 232. The lower end of the folding rod 235 is inserted into the planetary gear 232 to rotate on a fixed axis, and the upper end is tightly connected to the collar 224. This allows the collar 224 to drive the auxiliary blade 223 to rotate in the opposite direction through the lower support, thereby improving the shearing emulsification efficiency between the main blade 222 and the auxiliary blade 223. The collar 224 is guided to rotate through the mounting groove 2212. The collar 224 fits against the wall of the mounting groove 2212, sealing the mounting groove 2212 and preventing the emulsion from entering the transmission cavity 2211 through the mounting groove 2212.

[0044] like Figure 5 As shown, the main blade 222 has a top arc 2221 on the outer side and the auxiliary blade 223 has a shear groove 2231 on the inner side. The top arc 2221 and the shear groove 2231 are collinear.

[0045] The main blade 222 has an arc-shaped outer side and a straight inner side. When the main blade 222 rotates, the liquid flows through the inner and outer sides of the main blade 222 in a differential flow pattern. The outer side has a faster flow velocity and lower pressure, while the inner side has a slower flow velocity and higher pressure, which pushes the inner liquid to flow outward, improving the internal and external displacement efficiency. A shear groove 2231 is provided on the inner side of the auxiliary blade 223 and is arranged concentrically with the top arc 2221 to prevent motion interference and improve the smoothness of shear flow, thereby ensuring emulsification efficiency.

[0046] like Figure 5 As shown, the number of auxiliary blades 223 on the lower connecting rod is one less than the number of main blades 222 on the adjacent upper connecting rod. The outermost main blade 222 of the upper connecting rod and the wall of the emulsion cavity 11 form a shear gap.

[0047] An upper connecting rod and a lower connecting rod constitute a shear group. Each shear group has one more main blade 222 than auxiliary blade 223. The outermost main blade 222 and the wall of the emulsion chamber 11 constitute shear flow.

[0048] like Figure 1 , Figures 6-7As shown, the circulation device 3 also includes a monitoring component 32. The transfer box 4 is provided with a circulation chamber 44. The circulation pump 31 and the circulation chamber 44 are connected by a pipe. The monitoring component 32 includes a float 321 and an induction coil 323. There are several floats 321. Several floats 321 extend upward with guide rods 322. The guide rods 322 are made of magnetic material. Several detection slots 41 are provided on the upper side of the circulation chamber 44. The guide rods 322 are inserted into the detection slots 41. The induction coil 323 is placed in the detection slots 41. The float 321 is provided with a pressure-sensing slot 3212. The opening of the pressure-sensing slot 3212 is set downward.

[0049] The dispersed phase of the circulating liquid is detected by the monitoring component 32. After one cycle of emulsification is completed, the circulating pump 31 pumps the emulsion into the circulating chamber 44 in stages. Multiple floats 321 are sequentially attached and can slide relative to each other. Due to the high viscosity and surface tension of the emulsion, it cannot penetrate through the gaps between adjacent floats 321. The circulating chamber 44 has multiple inlets facing the pressure-sensing grooves 3212 of the floats 321. During liquid injection, the pressure-sensing grooves 3212 are filled first. As the liquid is injected, all floats 321 rise at a uniform speed. When they float to a fixed height, no more emulsion is injected. If there is a dispersed phase in the emulsion at this time, due to the low density of the dispersed phase, it will float to the surface. During the process, the surrounding emulsion simultaneously fills the upward-facing area, ensuring that all floats 321 remain at the same height. When the dispersed phase floats to the pressure-sensing tank 3212, it passes over the emulsion and rises to the top layer. Since the pressure-sensing tank 3212 is a downward-opening groove, the dispersed phase, after entering this pressure-sensing tank 3212, will not flow to other pressure-sensing tanks 3212. Under the action of buoyancy, it pushes the float 321 here to move upward, and drives the guide rod 322 to move upward. The induction coil 323 cuts the magnetic field lines, generates an induced current, and forms a detection circuit. That is, when the current of several detection circuits produces a difference, it indicates that there is a dispersed phase in the circulation chamber 44 at this time, and the emulsification is incomplete. It needs to be sent into the emulsification chamber 11 for further emulsification.

[0050] As an optimization, a circulation channel 42 is provided on one side of the transfer box 4. The circulation channel 42 is connected to the shut-off valve 5, and several induction coils 323 are electrically connected to the shut-off valve 5. The shut-off valve 5 can be powered by an external power source. Based on the current value generated by the detection circuit, it detects whether the dispersed phase is completely emulsified. If the emulsification is incomplete, it controls the shut-off valve 5 to be in the open state.

[0051] As an optimization, the transfer box 4 is equipped with a discharge channel 43, the height of which is higher than that of the circulation channel 42. This height difference ensures that when emulsification is complete, the shut-off valve 5 is in the shut-off state, allowing the emulsion to be sent through the discharge channel 43 to subsequent processing steps, preventing the emulsion from recirculating and improving emulsification efficiency.

[0052] As an optimization, the float 321 is provided with a balance cavity 3211. The balance cavity 3211 on the float 321 is a sealed chamber used to balance the weight of the float 321, so that the buoyancy generated by the dispersed phase can push the float 321 upward, thereby improving the detection accuracy of the dispersed phase.

[0053] The working principle of this invention is as follows: When the planetary gear 232 rotates, the guide wheel 233 is fixed to the wall of the emulsification chamber 11 by the bracket 234, causing the planetary gear 232 to revolve around the center line of the guide wheel 233. The direction of the revolution is the same as the direction of the rotation, thereby driving the collar 224 to rotate through the folding rod 235. The rotation axis of the collar 224 coincides with the revolution axis of the planetary gear 232. The lower end of the folding rod 235 is inserted into the planetary gear 232 to rotate on a fixed axis, and the upper end is tightly connected to the collar 224. This causes the collar 224 to drive the auxiliary blade 223 to rotate in the opposite direction via the lower support, improving the shear emulsification efficiency between the main blade 222 and the auxiliary blade 223. When the main blade 222 rotates, the liquid flows at a differential speed as it passes through the inner and outer sides of the main blade 222. The outer side has a faster flow velocity and lower pressure, while the inner side has a slower flow velocity and higher pressure, pushing the inner liquid to flow outward, thus improving the internal and external displacement efficiency. A shear groove 2231 is provided on the inner side of the auxiliary blade 223, and it is connected to the top arc. 2221 are arranged in concentric circles to prevent motion interference and improve the smoothness of shear flow, thereby ensuring emulsification efficiency. When the float reaches a fixed layer height, no more emulsion is injected. If there is a dispersed phase in the emulsion at this time, due to the low density of the dispersed phase, the surrounding emulsion fills the space to which it floats during the floating process, so that all floats 321 are still at the same layer height. When the dispersed phase floats to the pressure-sensing tank 3212 and crosses the emulsion, it floats to the top layer. Since the pressure-sensing tank 3212 is a downward-opening groove, the dispersed phase will not flow to other pressure-sensing tanks 3212 after entering this pressure-sensing tank 3212. Under the action of buoyancy, the float 321 here is pushed upward and the guide rod 322 is moved upward. The induction coil 323 cuts the magnetic field lines, generates an induced current, and forms a detection circuit. That is, when the current of several detection circuits produces a difference, it indicates that there is a dispersed phase in the circulation chamber 44 at this time, and the emulsification is incomplete. It needs to be sent into the emulsification chamber 11 for further emulsification.
