Description

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 colloid is a highly hydrophilic polymer material that can dissolve or swell in water to form a relatively viscous aqueous solution or dispersion system, which is usually called a polymer aqueous solution or a hydrosol. The hydrophilic groups in the water-soluble colloid not only make it water-soluble, but also have chemical functions, as well as dispersion, flocculation, viscosity increase, drag reduction, adhesion, film formation, gel formation, chelation and other physical functions. Therefore, this water-soluble colloid is widely used in the daily chemical, food and pharmaceutical industries.

[0003] Due to the complexity of the structure of polymer compounds: large molecular weight and polydispersity, its dissolution phenomenon is much more complicated than the dissolution of small molecular substances. The size of polymer and solvent molecules is very different, and the molecular movement speed of the two is also very different. Solvent molecules can penetrate into polymers relatively quickly, while the diffusion of polymers into solvents is very slow. In this way, the dissolution process of polymers goes through two stages. First, solvent molecules penetrate into the interior of the polymer, causing the volume of the polymer to expand, which is called "swelling". Then the polymer is evenly dispersed in the solvent to form a homogeneous system of completely dissolved molecular dispersion. The entire dissolution process takes a long time and usually requires stirring, shearing and homogenization. At the same time, in order to accelerate the dissolution of certain polymer colloids, it is necessary to proceed at a higher temperature.

[0004] Water-soluble colloids are widely used in food and are an indispensable part of food ingredients in some food varieties, playing an important role. For example, in the food industry, gel jelly products, soft candy products, soft capsules and other products all need to use water-soluble colloids and be configured into hydrosol liquids 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 dissolving: diluting by adding white sugar, glucose syrup and water into a sugar dissolving tank; sol: transferring the diluted solution to a colloid tank and adding plant gum and a large amount of water for high-temperature sol; sugar boiling: transferring the sol to a sugar boiling tank for boiling, filtering out the water therein to obtain syrup; temporary storage: transferring the obtained syrup to a temporary storage tank for temporary storage; sugar solution preparation: transferring the sugar solution in the temporary storage tank to an efficacy mixing tank, and adding the required efficacy ingredients to obtain the required hydrosol liquid of jelly candies.

[0006] The above-mentioned hydrosol liquid process requires the steps of sugar dissolution, sol, sugar boiling and functional stirring and mixing. The preparation process requires multiple people to carry out step-by-step according to the production process. The operators have high workload, 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 has high production costs. Summary of the invention

[0007] In view of the deficiencies in 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 consumed in the entire process.

[0008] The present invention is achieved through the following technical solutions:

[0009] A method for preparing a hydrosol comprises the following steps:

[0010] 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 various feeding stations of the hydrosol solution preparation system according to the material properties for standby;

[0013] Start the mixing and shearing equipment of the hydrocolloid solution preparation system, open each feeding station synchronously, and convey each material to the processing pipeline at the configured flow rate. The first screw in the processing pipeline mixes and shears all the materials at the same time to obtain a uniform hydrosol solution.

[0014] Furthermore, the step of classifying the total materials required for the preparation of the hydrosol solution according to the material properties, and respectively configuring the classified materials to various feeding stations of the hydrosol solution preparation system according to the material properties for standby use, specifically includes the following steps:

[0015] 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 the properties of the materials;

[0016] 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;

[0017] Each feeding unit is temperature controlled according to the material properties of each material for standby use.

[0018] Furthermore, the step of starting the mixing and shearing equipment of the hydrocolloid solution preparation system, opening each feeding station synchronously, 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:

[0019] Start the mixing and shearing equipment of the water-based gel solution preparation system and open each feeding station simultaneously;

[0020] The solid phase material and the water phase material enter the processing pipeline from the upstream end of the processing pipeline. The solid phase material and the water 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.

[0021] 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;

[0022] 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;

[0023] A uniform aqueous solution is obtained at the outlet of the processing pipeline.

[0024] 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:

[0025] 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.

[0026] Furthermore, the step of calculating and configuring the flow rate of each material property entering the processing pipeline specifically includes:

[0027] Calculate the flow rate of each material property into the processing pipeline;

[0028] The calculated material flow rate value for each material property is allocated to each feeding station.

[0029] Furthermore, the step of calculating the flow rate of each material property entering the processing pipeline specifically includes:

[0030] Define the discharge flow rate of the processing pipeline outlet as V 出 , V 出 The range is 50-300kg / h;

[0031] The flow rate of various materials entering the processing pipeline meets the following conditions:

[0032] V a =V 出 ×a;

[0033] V b =V 出 ×b;

[0034] V c =V 出 ×c;

[0035] V d =V 出 ×d;

[0036] Ve=V 出 ×e;

[0037] 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.

[0038] Further, 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:

[0039] Turn on the electromagnetic infrared heater to preheat the processing pipeline of the mixing and shearing equipment;

[0040] 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:

[0041] 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.

[0042] If the first temperature sensor detects that the temperature value is higher than the preset maximum value, the heating is stopped;

[0043] The temperature in the processing pipeline is controlled within the temperature range required for the processing of the hydrosol liquid.

[0044] A preparation system based on the above-mentioned preparation method of the hydrosol solution comprises:

[0045] Mixing and shearing equipment;

[0046] Controller;

[0047] Multiple feeding stations, used to store materials of different material properties;

[0048] 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 material conveying speeds of the multiple feeding stations. 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.

[0049] Furthermore, the mixing and shearing equipment includes a processing pipeline, a first screw and a driving 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 driving 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 port of the processing pipeline.

[0050] 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.

[0051] Compared with the prior art, the advantages of the present invention are:

[0052] 1. The system and preparation method can be used in the preparation process of water-soluble glue in daily chemicals, food and medicine, and can also introduce various functional ingredients and auxiliary materials online synchronously, especially in the more viscous water-soluble system, such as in the preparation of gel jelly glue, soft capsule glue, soft candy liquid, etc.

[0053] 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 water phase materials are connected on the side of the processing pipeline close to the driving motor, so that the materials entering the online material mixing and shearing equipment are fully dispersed, dissolved and sheared. Then, 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, which 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 a higher functional content and better quality.

[0054] 3. Compared with the traditional glue liquid preparation process, this process changes the process of gradually adding materials, mixing and boiling. It adopts material mixing and shearing equipment and quantitative feeding system to connect the glue liquid preparation process in series, 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 is 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.

[0055] 4. The system and process for preparing the aqueous solution is short in time. From the entry of various materials 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, which greatly improves production efficiency.

[0056] 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 controller 200 is electrically connected to the plurality of feeding stations 300 and controls the material conveying speed of each feeding station 300. 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 of different material properties to obtain a hydrosol liquid, which is discharged from the mixing and shearing device 100 after processing.

[0065] The mixing and shearing equipment 100 includes a processing pipeline 101, a first screw 102, a driving motor 103 and an electromagnetic infrared heater 104. The feeding station 300 is connected to the processing pipeline 101 for conveying materials of different material properties into the processing pipeline 101. The electromagnetic infrared heater 104 is arranged on the outside of the processing pipeline 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 pipeline 101.

[0070] A pressure sensor 106 is provided at the discharge port 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 port 110 is higher than the set threshold, a feedback signal is given to the controller 200, and the controller 200 controls the driving motor 103 to reduce the speed, and vice versa, increases the speed of the driving motor 103.

[0071] A first temperature sensor 107 is provided in the processing pipeline 101 for monitoring the temperature of the material in the processing pipeline 101, and a second temperature sensor 108 is provided in the insulation cover 105.

[0171] 1. The system and preparation method can be used in the preparation process of water-soluble glue in daily chemicals, food and medicine, and can also introduce various functional ingredients and auxiliary materials online synchronously, especially in the more viscous water-soluble system, such as in the preparation of gel jelly glue, soft capsule glue, soft candy liquid, etc.

[0172] 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 water phase materials are connected on the side of the processing pipeline close to the driving motor, so that the materials entering the online material mixing and shearing equipment are fully dispersed, dissolved and sheared. Then, 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, which 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 a higher functional content and better quality.

[0173] 3. Compared with the traditional glue liquid preparation process, this process changes the process of gradually adding materials, mixing and boiling. It adopts material mixing and shearing equipment and quantitative feeding system to connect the glue liquid preparation process in series, 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 is 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.

[0174] 4. The system and process for preparing the aqueous solution is short in time. From the entry of various materials 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, which greatly improves production efficiency.

[0175] 5. Reduce the workload of operators, simplify the production process, increase continuity, reduce the space occupied by the factory, and increase economic benefits.
