Description

TECHNICAL FIELD

[0001] The present application relates to the field of cream production, in particular to a cream production equipment and production process. BACKGROUND

[0002] Modern cream production generally uses an emulsification reaction kettle system, the core equipment includes an oil phase melting tank, a water phase dissolving tank, an emulsification reaction kettle with a stirring paddle, and a filling line. The basic process is: the oil phase components (wax esters, oils, etc.) are heated to 60-80℃ for melting, the water phase components (water, humectants, etc.) are dissolved and then injected into the oil phase, mechanically stirred to form an emulsion, and then cooled to add active substances, and finally vacuum defoaming and filling. This system is committed to balancing the three core indicators of cream stability, active ingredient effectiveness, and skin feel, supporting the trillion-level beauty industry.

[0003] However, the existing equipment has inherent limitations: the one-way fixed-axis stirring mode does not fully break up the oil phase droplets, and the 5-50μm unemulsified particles aggregate during the storage period, causing stratification; the static stirring forms a boundary layer on the tank wall, which induces cream coking and wall sticking, forcing each batch to be shut down for manual cleaning - the risk of operators being exposed to strong alkaline cleaners continues to exist, and more seriously, the equipment cannot balance high-efficiency dispersion and safe cleaning, increasing the stirring intensity improves the emulsification degree, but accelerates the degradation of heat-sensitive materials and mechanical wear. This equipment defect further exacerbates the process bottleneck: rough oil phase processing leaves lipid crystal defects, causing oil leakage in the final product; static injection of the water phase leads to phase separation, and prolonging the high-temperature emulsification time accelerates the decomposition of active substances; the vacuum defoaming and quenching processes are disconnected, forming a loose crystal network that makes the cream feel both gritty and greasy. These defects form a vicious cycle - improving stability requires sacrificing active ingredients, and optimizing skin feel increases energy consumption. Ultimately, the separation of equipment and process has led to industry-level conflicts: high-viscosity systems require increased shear force to achieve instantaneous dispersion, but existing technologies rely on high-temperature / long-time stirring; the risk of chemical cleaning increases with production capacity, but there is a lack of in-situ cleaning solutions. This has long trapped the industry in a "quality-efficiency-safety" triangle dilemma, and a revolutionary solution is urgently needed.

[0004] Chinese Patent No. CN218609057U discloses a mixing device for cream production, which includes support frames, mixing tanks, overturning structures, mixing structures, and raw material boxes.

[0024] The floating assembly 3 rotates as a whole with the rotating shaft 23, and the pulley 33 is always in contact with the top end of the arc-shaped seat 31 in the process, thereby driving the rotating shaft 23 as a whole to rise and fall.

[0025] The rotating stirring rod 24 and the fixed rod 27 generate radial fluid shear force, and synchronous up and down shaking forms axial vortex, double action forces oil phase microdroplet to be deeply broken and dispersed in water phase matrix, and completely eliminates unemulsified particles in the traditional process of cream production.

[0027] The one-way shaft 41 in the above can only rotate counterclockwise, when the motor 21 rotates clockwise, the one-way shaft 41 remains stationary, in this state, the motor 21 can drive the rotating shaft 23 as a whole to stir the cream raw materials, and when the motor 21 rotates counterclockwise, the one-way shaft 41 rotates with the motor 21, thereby driving the belt pulley transmission mechanism 42 and the reciprocating rod 43 to rotate.

[0028] The inner surface of the sliding plate 44 is slidably connected with a limiting column 45 on both sides, the lower ends of the two limiting columns 45 are fixedly connected with the tank body 1, and the lower ends of the two limiting columns 45 are fixedly connected with the tank body 1.

[0029] The limiting column 45 in the above can limit the sliding plate 44, so that it can stably ascend and descend; The water bag 46 is internally provided with a specific cleaning agent, which can sufficiently clean the oily substances in the raw materials, and the bottom end and the side surface of the water bag 46 are provided with one-way valves, the one-way valve at the bottom end can only discharge the cleaning agent outward, and cannot intake water, and the one-way valve at the side surface can only fill the cleaning agent into the water bag 46, and cannot discharge water, wherein the one-way valve at the side surface is connected with an external cleaning agent storage tank.

[0030] Further, the reciprocating rod 43 in the above is a ball screw mechanism in the prior art, which can drive the sliding plate 44 to reciprocate and ascend and descend.

[0031] The raw materials are poured into the inside of the tank body 1 from the feeding port 11, the motor 21 is started to drive the rotating shaft 23, the stirring rod 24 and the connecting rod one 25 and other structures to rotate clockwise, the raw materials in the inside of the tank body 1 are stirred, the emulsification efficiency is improved, the pulley 33 slides on the arc surface at the upper end of the arc-shaped seat 31 during the stirring process, so that the rotating shaft 23, the stirring rod 24, the connecting rod one 25 and the cleaning brush 26 are driven to vibrate up and down as a whole, the oil phase micro-droplets are forced to be broken and dispersed in the water phase matrix, and the unemulsified particles in the traditional process are completely eliminated, after the stirring is completed, the raw materials are discharged from the discharging port 12, and then the inside of the tank body 1 is cleaned; When cleaning, an appropriate amount of water is poured into the inside of the tank body 1, the motor 21 is controlled to drive the rotating shaft 23 to rotate counterclockwise, the one-way shaft 41 also rotates synchronously during the rotating process, so that the reciprocating rod 43 is driven to rotate, and then the sliding plate 44 starts to move up and down reciprocally, the cleaning agent in the water bag 46 is continuously extruded into the inside of the tank body 1, and the zero-interval conversion from production to cleaning is realized.

[0032] Therefore, through the cooperation of various components, the stirring rod 24 can be rapidly up and down during the stirring process in the forward rotation, the oil phase micro-droplets are forced to be broken and dispersed in the water phase matrix, the unemulsified particles in the traditional process are completely eliminated, the high-frequency vibration continuously refreshes the boundary layer of the stirring tank wall, the cleaning brush 26 effectively inhibits the coking and wall-hanging phenomenon of the high-viscosity paste on the heat transfer surface, and the pre-stored cleaning agent can be smoothly injected into the tank body 1 through the water bag 46 in the reverse rotation, the seamless connection of the production and cleaning processes is realized, and the operation hidden danger of personnel contacting the chemical cleaning agent is greatly reduced.

[0033] Embodiment two, refer to Figure 6 A face cream production process, comprising the following steps: S1, oil phase high-pressure homogenization pretreatment: the oil phase material is independently melted and subjected to 10-15MPa high-pressure homogenization; S2, dynamic metering injection of water phase: the water phase pre-cooled to 45-50 DEG C is injected into the oil phase at a flow rate of 0.5-1.5 mL / s; S3, synchronous high-shear emulsification: the injection process is synchronously carried out at 8000-12000 rpm high-shear emulsification; S4, low-temperature integration of heat-sensitive active substances: the heat-sensitive active substances are added after being cooled to 35-40 DEG C and switched to 300-500 rpm low-speed homogenization; S5, negative pressure directional curing: stirring and curing for 20 min under a vacuum degree of-0.08-0.1 MPa; S6, program-controlled temperature filling: cooling to 25 DEG C at a gradient of 1 DEG C / min and filling under the protection of nitrogen.

[0034] The specific implementation process is as follows: Raw material pretreatment and primary emulsification After the oil phase components (shea butter, squalane, etc.) were completely liquefied in a 60°C melting kettle, they were continuously processed by a two-stage valve of a high-pressure homogenizer: the first valve core (pore size 2 mm / 8 MPa) broke up large particle aggregates, and the second valve core (pore size 0.5 mm / 12 MPa) reduced the lipid particle size from the initial 50 μm to ≤5 μm. The processed oil phase was transferred to a jacketed reaction kettle, which was maintained at a constant temperature of 60°C. At the same time, the water phase materials (glycerol, sodium hyaluronate solution) were dissolved at 80°C and then cooled to 48°C. They were accurately injected into the oil phase at a rate of 1.0 mL / s by a servo metering pump equipped with a PID closed-loop system. Based on real-time feedback from an electromagnetic flowmeter, the stepping motor speed was adjusted, and the flow rate fluctuation was ≤±2%. Then, the injection was started immediately (delay ≤0.5 s), and a rotor-stator emulsification head at a distance of 10 cm from the injection port was sheared at a high speed of 12000 rpm to form a vortex forced adsorption zone, realizing the spatiotemporal coupling of water phase injection trajectory and high shear flow field.

[0035] Integration of low-temperature active substances When the mixed system was cooled to 38°C in a jacket (temperature sensor accuracy ±0.5°C), the heat-sensitive active substance (such as ceramide nanoliposomes) was added, and the stirring mode was immediately switched: the high-shear emulsification head was turned off, and the stirring device was started. In this stage, the low-shear field was used to protect the molecular structure, and the uniformity of the active ingredient dispersion (CV value) was more than 95%, while avoiding the rupture of the liposome vesicle.

[0036] Vacuum maturation control All feed ports were closed, and the vacuum system was started to draw to -0.09 MPa (pressure sensor range -0.1~0 MPa). This threshold was determined by ceramide volatility experiments: when the pressure was lower than -0.1 MPa, the air supply valve was automatically opened to prevent the loss of ingredients. Under constant pressure, the frame stirring paddle was operated at a low speed of 30 rpm for 20 min. At this time, the vacuum system was combined with a condensation reflux device to condense and recover the volatile trace water molecules, while the air components were adsorbed and discharged by molecular sieves. This process reduced the diameter of the microbubbles in the system from the initial 200 μm to ≤50 μm, and the bubble escape rate was increased by 40%, achieving negative pressure directional bubble escape and molecular arrangement optimization.

[0037] Gradient cooling and filling After the aging is completed, the program temperature control module is started: the cooling medium is introduced into the jacket through a proportional regulating valve in three stages - 40→35℃ stage at a rate of 2℃ / min (cooling water flow rate 70%), 35→30℃ stage at a rate of 1℃ / min (cooling water 50%), and 30→25℃ stage at a rate of 0.5℃ / min (cooling water 30%). When the temperature sensor detects 25℃, the reactor is filled with high-purity nitrogen to replace the air to an oxygen content of <0.5%, and then the filling is carried out under positive pressure (+0.05MPa) with the filling head 5cm from the bottle mouth and the nitrogen curtain continuously covering the surface of the paste.

[0038] The oil phase in the S1 step is treated by high-pressure homogenization at 10-15MPa, the water phase injection flow rate in the S2 step is dynamically regulated by a metering pump, the vacuum degree in the aging stage in the S5 step is -0.08-0.1MPa, and the gradient cooling in the S6 step is programmed to decrease at a rate of 1℃ / min.

[0039] Further, the high-pressure homogenization adopts a two-stage valve structure, the first-stage valve core has a hole diameter of 2mm / pressure of 8MPa, the second-stage valve core has a hole diameter of 0.5mm / pressure of 12MPa, and the lipid particle size is reduced from the initial 50μm to ≤5μm; The metering pump is equipped with a PID closed-loop control system, which adjusts the stepping motor speed based on the real-time data feedback of the flowmeter, and the flow rate deviation compensation time is ≤0.2; The programmed cooling is divided into three stages: 40→35℃ 2℃ / min, 35→30℃ 1℃ / min, and 30→25℃ 0.5℃ / min, and the cooling medium flow rate proportional valve is adjusted at each stage temperature difference trigger.

[0040] Specifically, the high-pressure homogenization system adopts a differential two-stage valve design: the first-stage valve (hole diameter 2mm / pressure 8MPa) realizes coarse crushing of the lipid mass (50μm→20-30μm) through turbulent shear, the second-stage valve (hole diameter 0.5mm / pressure 12MPa) generates ultra-high shear rate (10 6 / s) by using a micro-groove rectification structure, and grinds the lipids to ≤5μm under the action of pressure gradient jump (8→12MPa). The valve body is integrated with a double-channel dynamic cooling system, which regulates the cooling water flow rate (first-stage valve 2L / min / 60℃, second-stage valve 4L / min / 55℃) in real time according to the pressure-temperature coupling model, and prevents lipid oxidation caused by local overheating.

[0041] Online laser particle size analyzer realizes closed loop control of particle size-temperature-pressure: when the outlet D50>5μm, the secondary valve pressure is automatically increased to 13MPa and the cooling 0.5L / min is automatically connected (response≤1.5s), to ensure that the particle size span index≤0.9, the design is 37% energy saving compared with the traditional homogenization, the blockage rate is reduced by 82%, and the output monodisperse liposome (viscosity<350mPa·s) provides ideal fluid conditions for subsequent dynamic metering injection, and eliminates the risk of phase separation.

[0042] It should be particularly pointed out that the specific installation mode of the motor 21 and the connection mode of the circuit and the control method used in the application all belong to conventional design, and the application will not be described in detail.

[0043] The above shows and describes the basic principles and main features of the application and the advantages of the application. Those skilled in the art should understand that the application is not limited to the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the application, and various changes and improvements can be made without departing from the spirit and scope of the application, and these changes and improvements all fall within the scope of the application claimed.
