Description

A method for preparing a hydrosol Technical Field

[0001] The invention relates to the field of hydrosol processing, and in particular to a method for preparing a hydrosol. Background Art

[0002] Water-soluble colloids are highly hydrophilic polymers that dissolve or swell in water to form relatively viscous aqueous solutions or dispersions, commonly referred to as polymer solutions or hydrosols. The hydrophilic groups in water-soluble colloids not only impart water solubility but also possess a variety of chemical and physical properties, including dispersion, flocculation, viscosity enhancement, drag reduction, adhesion, film formation, gel formation, and chelation. Consequently, these water-soluble colloids are widely used in the daily chemical, food, and pharmaceutical industries.

[0003] Due to the structural complexity of polymer compounds, their large molecular weight and polydispersity, their dissolution is much more complex than that of small molecules. The size of polymers and solvent molecules differ significantly, as do their molecular motion speeds. Solvent molecules can penetrate the polymer relatively quickly, while the polymer diffuses into the solvent very slowly. Consequently, the polymer dissolution process proceeds through two stages: first, the solvent molecules penetrate the polymer, causing it to expand in volume (known as "swelling"). Then, the polymer is evenly dispersed in the solvent, forming a fully dissolved, molecularly dispersed homogeneous system. This entire dissolution process takes a long time and often requires stirring, shearing, and other conditions for homogenization. Furthermore, to accelerate the dissolution of certain polymer colloids, higher temperatures are required.

[0004] Water-soluble colloids are widely used in food and are essential ingredients for many food products. For example, gel jelly products, soft candy products, and soft capsules in the food industry all require the use of water-soluble colloids and are formulated into a hydrosol solution to obtain the final product.

[0005] The existing hydrosol liquid preparation process, such as the hydrosol liquid process for preparing jelly candies, has the following preparation process: sugar disintegration: dilution by adding white sugar, glucose syrup and water into a sugar disintegration tank; sol: the diluted solution is transported to a colloid tank and plant gum and a large amount of water are added to perform high-temperature sol; sugar boiling: after the sol, the solution is transferred to a sugar boiling tank for boiling, and the water therein is filtered out to obtain syrup; temporary storage: the obtained syrup is transported to a temporary storage tank for temporary storage; sugar solution preparation: the sugar solution in the temporary storage tank is transported to an efficacy mixing tank, and the required efficacy ingredients are added to obtain the required hydrosol liquid of jelly candies.

[0006] The above-mentioned hydrosol liquid process requires the steps of sugar dissolution, colloidal solution, sugar boiling and functional stirring and mixing. The preparation process requires multiple people to carry out the process step by step according to the production process. The workload of the operators is high, and the production process is cumbersome and has poor continuity. The entire preparation process takes 4-5 hours. The entire process is time-consuming and the production cost is high.

[0007] Summary of the Invention

[0008] In view of the shortcomings of the prior art, the present invention provides a method for preparing a hydrosol solution, which reduces the workload of operators, has a simple production process, high continuity, and reduces the time spent on the entire process.

[0009] The present invention is achieved through the following technical solutions:

[0010] A method for preparing a hydrosol comprises the following steps:

[0011] The total materials required for the preparation of the hydrosol solution are classified according to the material properties, and the classified materials are respectively allocated to the various feeding stations of the hydrosol solution preparation system according to the material properties for standby;

[0012] Turn on the heating system of the hydrocolloid solution preparation system to preheat the processing pipeline of the mixing and shearing equipment so that the temperature in the processing pipeline meets the processing requirements of the hydrosol solution;

[0013] Calculate and configure the flow rate of each material property entering the processing pipeline;

[0014] Start the mixing and shearing equipment of the hydrocolloid solution preparation system, open each feeding station simultaneously, and deliver each material to the processing pipeline at the configured flow rate. The first screw in the processing pipeline mixes and shears all materials at the same time to obtain a uniform hydrosol solution.

[0015] Furthermore, the step of classifying the total materials required for the preparation of the hydrosol solution according to the material properties, and respectively allocating the classified materials to the various feeding stations of the hydrosol solution preparation system according to the material properties for standby use specifically includes the following steps:

[0016] Classifying the total materials required for preparing the hydrosol into solid phase materials, water phase materials, water phase functional materials, oil phase functional materials and other ingredients according to their properties;

[0017] At the same time, the solid phase material is configured to the first feeding unit, the water phase material is configured to the second feeding unit, the water phase functional material is configured to the third feeding unit, the oil phase functional material is configured to the fourth feeding unit, and the other ingredients are configured to the fifth feeding unit;

[0018] Each feeding unit is temperature controlled according to the material properties of each material for standby use.

[0019] Furthermore, the step of starting the mixing and shearing equipment of the hydrocolloid solution preparation system, synchronously opening each feeding station, delivering each material to the processing pipeline at a configured flow rate, and the first screw in the processing pipeline simultaneously mixing and shearing all the materials to obtain a uniform hydrosol solution specifically includes the following steps:

[0020] Start the mixing and shearing equipment of the water-based solution preparation system and simultaneously open each feeding station;

[0021] The solid phase material and the aqueous phase material enter the processing pipeline from the upstream end. The solid phase material and the aqueous phase material are initially sheared and mixed under the action of the first screw and then transported to the downstream end of the processing pipeline.

[0022] The water-phase functional materials, oil-phase functional materials and other ingredients enter the processing pipeline from the downstream end, and are preliminarily mixed with the solid-phase material and water-phase material mixture at the upstream end, and are further transported toward the discharge outlet;

[0023] The water phase functional materials, oil phase functional materials and other ingredients are sheared and mixed again with the mixture of solid phase materials and water phase materials, and then discharged from the processing pipeline;

[0024] A uniform aqueous solution is obtained at the outlet of the processing pipeline.

[0025] Furthermore, the step of starting the mixing and shearing equipment of the hydrocolloid solution preparation system, synchronously opening each feeding station, delivering each material to the processing pipeline at a configured flow rate, and the first screw in the processing pipeline simultaneously mixing and shearing all the materials to obtain a uniform hydrosol solution also includes the following steps:

[0026] Discard the solid phase materials, water phase materials, water phase functional materials, oil phase functional materials and other ingredients that are not fully mixed in the processing pipeline in the early stage of the mixing and shearing equipment.

[0027] Furthermore, the step of calculating and configuring the flow rate of each material property entering the processing pipeline specifically includes:

[0028] Calculate the flow rate of each material property into the processing pipeline;

[0029] The calculated material flow rate value for each material property is allocated to each feeding station.

[0030] Furthermore, the step of calculating the flow rate of each material property entering the processing pipeline specifically includes:

[0031] Define the discharge flow rate of the processing pipeline outlet as V 出 , V 出 The range is 50-300kg / h;

[0032] The flow rate of various materials entering the processing pipeline meets the following conditions: V a =V 出 ×a; V b =V 出 ×b; V c =V 出 ×c; V d =V 出 ×d; Ve=V 出 ×e;

[0033] Among them, V a 、V b 、V c 、V d 、V e are the flow rates of solid phase materials, water phase materials, water phase functional materials, oil phase functional materials and other ingredients entering the processing pipeline; a, b, c, d, e are the mass proportions of solid phase materials, water phase materials, water phase functional materials, oil phase functional materials and other ingredients in the total materials.

[0034] Furthermore, the step of turning on the heating system of the hydrocolloid solution preparation system to preheat the processing pipeline of the mixing and shearing equipment so that the temperature in the processing pipeline meets the processing requirements of the hydrosol solution specifically includes:

[0035] Turn on the electromagnetic infrared heater to preheat the processing pipeline of the mixing and shearing equipment;

[0036] The first temperature sensor is used to determine in real time whether the temperature in the processing pipeline meets the processing requirements of the hydrosol liquid:

[0037] If the first temperature sensor detects that the temperature is lower than the preset minimum value, the electromagnetic infrared heater will continue to heat the processing pipe of the mixing and shearing equipment.

[0038] If the first temperature sensor detects that the temperature value is higher than the preset maximum value, heating is stopped;

[0039] The temperature in the processing pipeline is controlled within the temperature range required for the processing of the hydrosol solution.

[0040] A preparation system based on the above-mentioned method for preparing the hydrosol solution comprises:

[0041] Mixing and shearing equipment;

[0042] Controller;

[0043] Multiple feeding stations, each used to store materials with different properties;

[0044] Multiple feeding stations are connected to the mixing and shearing equipment for conveying materials with different material properties to the mixing and shearing equipment. The controller is electrically connected to the multiple feeding stations for respectively controlling the speed at which the multiple feeding stations convey the materials. The controller is electrically connected to the mixing and shearing equipment for controlling the mixing and shearing equipment to mix and shear materials with different material properties.

[0045] Furthermore, the mixing and shearing equipment includes a processing pipeline, a first screw and a drive motor. The feeding station is connected to the processing pipeline for conveying materials with different material properties into the processing pipeline. The first screw is arranged in the processing pipeline. The drive motor and the controller are electrically connected to drive the first screw to mix and shear the materials in the processing pipeline to obtain the hydrosol liquid, and the first screw discharges the obtained hydrosol liquid from the discharge outlet of the processing pipeline.

[0046] Furthermore, the multiple feeding stations include a first feeding unit for storing solid phase materials, a second feeding unit for storing water phase materials, a third feeding unit for storing water phase functional materials, a fourth feeding unit for storing oil phase functional materials and a fifth feeding unit for storing other ingredients. The first feeding unit, the second feeding unit, the third feeding unit, the fourth feeding unit and the fifth feeding unit are all connected to the processing pipeline through pipelines.

[0047] Compared with the prior art, the advantages of the present invention are:

[0048] 1. The system and preparation method can be used in the configuration process of water-soluble glue in daily chemicals, foods and medicines, and can also simultaneously introduce various functional ingredients and auxiliary materials online. It has advantages especially in the configuration of relatively viscous water-soluble systems, such as gel jelly glue, soft capsule glue, soft candy glue, etc.

[0049] 2. This process and system also have unique advantages in the direction of heat-sensitive functional materials. The first feeding unit for storing solid phase materials and the second feeding unit for storing aqueous phase materials are connected on the side of the processing pipeline close to the drive motor. After the materials entering the online material mixing and shearing equipment are fully dispersed, dissolved and sheared, the third feeding unit and the fourth feeding unit for storing functional materials and the fifth feeding unit for storing other ingredients are connected near the outlet end of the processing pipeline. This reduces the heating, mixing and shearing time of the functional materials, greatly improves the stability of the functional ingredients, reduces the loss of nutrients, and makes the obtained hydrosol liquid have higher functional content and better quality.

[0050] 3. Compared with the traditional glue liquid preparation process, this process changes the process of gradual addition, mixing and boiling. It adopts material mixing and shearing equipment and quantitative feeding system in series to connect the glue liquid preparation process, and adopts digital automation to adjust the discharge rate according to the material ratio in the formula, which simplifies the glue liquid preparation process, makes the data of the glue liquid preparation process clearer, and the adjustment method more controllable, saving time and labor costs. Compared with batch production, this process can realize continuous production of glue liquid preparation, which can reduce production costs and improve labor efficiency.

[0051] 4. The system and process for preparing the aqueous solution takes a short time. From the entry of each material to the final preparation of the solution, it only takes the time of the online material mixing and shearing equipment, which reduces the time consumed by the entire process. The entire aqueous solution preparation time does not exceed 3 minutes, greatly improving production efficiency.

[0052] 5. Reduce the workload of operators, simplify the production process, increase continuity, reduce the space occupied by the factory, and increase economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and cannot be understood as limiting the present invention.

[0060] As shown in Figures 1-4, a system for preparing a hydrosol liquid according to an embodiment of the present invention includes a mixing and shearing device 100, a controller 200, multiple feeding stations 300 and a human-machine interface 600. The feeding station 300 is connected to the mixing and shearing device 100 through a pipeline 400 and conveys materials with different material properties to the mixing and shearing device 100. The controller 200 is electrically connected to the multiple feeding stations 300 and controls the speed at which each feeding station 300 conveys materials. The controller 200 is electrically connected to the mixing and shearing device 100 and controls the operation of the mixing and shearing device 100. The mixing and shearing device 100 is used to simultaneously mix and shear materials with different material properties to obtain a hydrosol liquid, which is discharged from the mixing and shearing device 100 after processing is completed. The human-machine interface 600 is electrically connected to the controller 200 for issuing work instructions and displaying various system parameters.

[0061] The mixing and shearing equipment 100 includes a processing pipe 101, a first screw 102, a drive motor 103 and an electromagnetic infrared heater 104. The feeding station 300 is connected to the processing pipe 101 for conveying materials with different material properties into the processing pipe 101. The electromagnetic infrared heater 104 is arranged on the outside of the processing pipe 101 and is electrically connected to the controller 200. An insulation sleeve 105 is provided on the outside of the electromagnetic infrared heater 104. The first screw 102 is arranged in the processing pipe 101. The drive motor 103 and the first screw 102 are fixedly connected, and the drive motor 103 and the controller 200 are electrically connected to drive the first screw 102 to simultaneously mix and shear all materials in the processing pipe 101 to obtain a hydrosol liquid. The first screw 102 discharges the obtained hydrosol liquid from the discharge port 110 of the processing pipe 101.

[0062] The mixing and shearing device 100 further includes a bottom plate 500 , on which the processing pipeline 101 and the driving motor 103 are fixedly arranged.

[0063] The base plate 500 includes a base 501 and a mounting plate 502 and a first support frame 503 fixed on the base 501. The processing pipe 101 is fixed above the first support frame 503. The drive motor 103 is fixed on the mounting plate 502, and the motor shaft of the drive motor 103 (not shown in the figure) passes through the first support frame 503 to drive the first screw 102 to rotate.

[0064] A second support frame 504 and a support plate 505 are also fixed to the mounting plate 502. The second support frame 504 is fixedly connected to the solid material pipeline 12, and the support plate 505 is fixedly connected to the motor 13. The second feeding unit 2, the third feeding unit 3, the fourth feeding unit 4, and the fifth feeding unit 5 are all fixed above the processing pipeline 101 via a mounting frame (not shown).

[0065] Specifically, the controller 200 controls the drive motor 103 to operate via the frequency converter 109 .

[0066] A pressure sensor 106 is provided at the discharge outlet 110, and the pressure sensor 106 is electrically connected to the controller 200. When the pressure sensor 106 detects that the pressure value at the discharge outlet 110 is higher than the set threshold, a feedback signal is sent to the controller 200, and the controller 200 controls the driving motor 103 to reduce the speed, and vice versa, to increase the speed of the driving motor 103.

[0067] A first temperature sensor 107 is provided within the processing pipe 101 to monitor the temperature of the material within the processing pipe 101. A second temperature sensor 108 is provided within the insulation jacket 105. Both the first temperature sensor 107 and the second temperature sensor 108 are connected to a controller 200. When the temperature of the first temperature sensor 107 or the second temperature sensor 108 is below a preset temperature, the controller 200 controls the electromagnetic infrared heater 104 to operate. Otherwise, the electromagnetic infrared heater 104 is deactivated to maintain the temperature within the processing pipe 101 within the temperature range required for processing the hydrosol. Alternatively, the controller 200 can control the electromagnetic infrared heater 104 to continuously heat the processing pipe 101, while the first temperature sensor 107 and the second temperature sensor 108 respectively monitor whether the temperatures within the processing pipe 101 and the insulation jacket 105 meet the operating requirements.

[0068] The processing pipe 101 is provided with a plurality of feed ports, and the number of the feed ports is consistent with the number of the feeding stations 300, ensuring that each feeding station 300 is connected to one of the feed ports. In this embodiment, five feed ports are provided, namely the first feed port 111, the second feed port 112, the third feed port 113, the fourth feed port 114 and the fifth feed port 115, wherein the first feed port 111 and the second feed port 112 are adjacently arranged on the processing pipe 101 at one end close to the drive motor 103, and the third feed port 113, the fourth feed port 114 and the fifth feed port 115 are adjacently arranged on the processing pipe 101 at one end close to the discharge port 110 (that is, the end of the processing pipe 101 away from the drive motor 103). Since the proportion of solid phase materials and water phase materials in the materials required for the hydrosol is relatively large, Here, the first feeding unit 1 for storing solid-phase materials and the second feeding unit 2 for storing aqueous-phase materials correspond to the first feeding port 111 and the second feeding port 112 respectively arranged adjacent to each other on the processing pipe 101 near one end of the driving motor 103, so as to allow the solid-phase materials and the aqueous-phase materials to have enough time to be sheared in the processing pipe 101, so as to achieve the purpose of sufficient shearing. After sufficient shearing, they are sheared and mixed with a small proportion of aqueous-phase functional materials, oil-phase functional materials and other ingredients. The equipment design is scientific and reasonable, saving unnecessary energy consumption.

[0069] In this embodiment, a twin-screw mixing and shearing device is used, and two completely identical first screws 102 work together to mix and shear the materials in the processing pipe 101. The diameter of the first screw 102 is 75 mm, and the first screw 102 includes multiple groups of propulsion sections 121 and shearing sections 122. The propulsion sections 121 and the shearing sections 122 are arranged at intervals from each other, and the propulsion section 121 is composed of multiple groups of propulsion thread modules 123, and the shearing section 122 is composed of multiple groups of shearing thread modules 124. The first feed port 111, the second feed port 112, the third feed port 113, the fourth feed port 114 and the fifth feed port 115 all correspond to the position of the advancement section 121 in the processing pipe 101, and the first feed port 111 and the second feed port 112 correspond to the same advancement section 121 in the processing pipe 101, and the third feed port 113, the fourth feed port 114 and the fifth feed port 115 correspond to the same advancement section 121 in the processing pipe 101. Further, the first screw 102 is located at the second feed port 112 (the first feed port 113).

The propulsion section 121 and the shearing section 122 of the first screw are spaced apart from each other, and the propulsion section 121 can mix different kinds of materials very quickly and shear them by the shearing section 122. The propulsion thread module 123 of the propulsion section 121 has a large thread pitch, and the distance the material is pushed per unit time is long, thereby improving the processing efficiency of the material.

In addition, the second batching tank 20, the third batching tank 30, the fourth batching tank 40, and the fifth batching tank 50 all have a heating function.

[0151] 1. The system and preparation method can be used in the configuration process of water-soluble glue in daily chemicals, foods and medicines, and can also simultaneously introduce various functional ingredients and auxiliary materials online. It has advantages especially in the configuration of relatively viscous water-soluble systems, such as gel jelly glue, soft capsule glue, soft candy glue, etc.

[0152] 2. This process and system also have unique advantages in the direction of heat-sensitive functional materials. The first feeding unit for storing solid phase materials and the second feeding unit for storing aqueous phase materials are connected on the side of the processing pipeline close to the drive motor. After the materials entering the online material mixing and shearing equipment are fully dispersed, dissolved and sheared, the third feeding unit and the fourth feeding unit for storing functional materials and the fifth feeding unit for storing other ingredients are connected near the outlet end of the processing pipeline. This reduces the heating, mixing and shearing time of the functional materials, greatly improves the stability of the functional ingredients, reduces the loss of nutrients, and makes the obtained hydrosol liquid have higher functional content and better quality.

[0153] 3. Compared with the traditional glue liquid preparation process, this process changes the process of gradual addition, mixing and boiling. It uses material mixing and shearing equipment and a quantitative feeding system in series to connect the glue liquid preparation process, and adopts a digital automation method to adjust the discharge rate according to the material ratio in the formula, which simplifies the glue liquid preparation process, makes the glue liquid preparation process data clearer, and the adjustment method more controllable, saving time and labor costs. Compared with batch production, this process can realize continuous production of glue liquid preparation, which can further reduce production costs and improve labor efficiency.

[0154] 4. The system and process for preparing the aqueous solution takes a short time. From the entry of each material to the final preparation of the solution, it only takes the time of the online material mixing and shearing equipment, which reduces the time consumed by the entire process. The entire aqueous solution preparation time does not exceed 3 minutes, greatly improving production efficiency.

[0155] 5. Reduce the workload of operators, simplify the production process, increase continuity, reduce the space occupied by the factory, and increase economic benefits.

[0156] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
