Description

Technical Field

[0001] This utility model relates to the field of food industry technology, and in particular to a pretreatment system for high viscosity thickeners. Background Technology

[0002] High-viscosity thickeners (such as konjac gum, carrageenan, xanthan gum, etc.) have high viscosity characteristics, often reaching tens of thousands to hundreds of thousands of centipoises, which presents several technical challenges to be addressed in their pretreatment: Such materials generally suffer from low efficiency and high labor intensity when fed manually or by traditional machinery, and are prone to bridging and blockage, resulting in uneven feeding, material splashing and dust diffusion. Meanwhile, because materials tend to adhere to the equipment walls and conveying components, conventional equipment (such as ordinary screw conveyors) struggles to achieve smooth conveying, frequently resulting in jamming, blockages, and cleaning problems, which seriously affect production continuity. 3) In addition, poor material dispersion during the feeding process can easily lead to clumping and uneven wetting, resulting in slow dissolution and inconsistent solute distribution in the subsequent dissolution stage, which ultimately affects the stability of the product's physicochemical properties and batch consistency.

[0003] In summary, especially for thickeners with high viscosity characteristics (such as konjac gum, carrageenan, xanthan gum, etc.), this utility model designs a pretreatment system for high viscosity thickeners that can overcome the above-mentioned defects of the prior art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pretreatment system for high-viscosity thickeners.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pretreatment system for a high-viscosity thickener, comprising: The system comprises a feeding auger with a feeding port at its top for feeding powdered materials. The auger is connected to a premixing tank at its bottom, through which the powdered materials are conveyed. The premixing tank has a water supply pipe on one side and a first pipeline at its bottom. A grinding mechanism is connected to the premixing tank via the first pipeline and to a glue storage tank via a second pipeline. Premixed materials are conveyed to the grinding mechanism via the first pipeline, and ground materials are conveyed to the glue storage tank via the second pipeline. As a further improvement, a control valve is provided on the water supply pipe. As a further improvement, the grinding mechanism is a colloid mill. As a further improvement, a stirring blade is installed inside the premixing tank, located at the bottom of the tank near the discharge port. As a further improvement, the stirring blade is a slanted turbine type.

[0006] As a further improvement to this solution, the water supply pipe is located at the top of the premixing tank.

[0007] This utility model is reasonably designed, easy to operate, has high feeding and dissolving efficiency, and is highly practical, with the following beneficial effects: 1) The feeding auger realizes the conveying of powder materials, effectively avoiding bridging of materials during the feeding process, and ensuring continuous, stable and controllable feeding; 2) The downward water flow impact force generated when water enters through the water supply pipe helps to drive the premixed material into the subsequent grinding mechanism; 3) The grinding mechanism is a colloid mill of existing technology. In this system, the thickener mill can finely crush the material through the shearing action between its stator and high-speed rotor. The gap between the stator and rotor can be controlled by adjusting the handle, thereby controlling the particle size of the material. The ground material is output by the impeller at the rear of the mill and transported to the glue storage tank through the pipeline to realize continuous production. Attached Figure Description

Detailed Implementation

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Referring to the figure, this utility model provides a pretreatment system for a high-viscosity thickener.

[0011] Example 1 A pretreatment system for a high-viscosity thickener, comprising: The feeding auger 2 has a feeding port 1 at its top, which is used for feeding powder materials. The feeding auger 2 is connected to the premixing tank 6 at its bottom, and the powder materials are transported to the premixing tank 6 through the feeding auger 2. A premixing tank 6 is provided with a water supply pipe 4 on one side and a pipe 71 at the bottom of the premixing tank 6. The grinding mechanism 8 is connected to the premixing tank 6 via pipe 71 and to the adhesive storage tank 13 via pipe 81.

[0012] The premixed material is transported to the grinding mechanism 8 through pipeline 1 71, and the ground material is transported to the adhesive storage tank 13 through pipeline 2 72.

[0013] As a further optimization, a control valve 5 is installed on the water supply pipe 4.

[0014] In this embodiment, a feeding and processing device for a high-viscosity thickener includes a feeding unit, a premixing unit, and a grinding and refining unit. The feeding unit mainly consists of a feeding port 1 and a feeding auger 2. The feeding port 1 is located above the feeding auger 2 and is used to feed powder thickener. The lower end of the feeding auger 2 is connected to the premixing tank 6, which can continuously and dust-free transport the powder to the premixing tank 6, effectively preventing bridging and splashing. The premixing tank 6 is equipped with a drive motor, a stirring paddle and a water supply pipe 4. The water supply pipe 4 is equipped with a flow meter and a control valve, which can accurately control the amount of water added. The bottom of the tank is provided with a discharge port and is connected to the grinding mechanism 8 through a pipe 71. The grinding mechanism 8 is a high-shear wet grinding machine. Its inlet is connected to pipeline 71, and its outlet is connected to the adhesive storage tank 13 through pipeline 81. The premixed slurry is further refined and dispersed in the grinding mechanism 8 after being subjected to high-speed shearing to form a uniform and stable adhesive, which is finally transported to the adhesive storage tank 13 for processing.

[0015] Example 2 The difference between Example 2 and Example 1 is as follows: 1) Grinding mechanism 8 is a colloid mill.

[0016] 2) The colloid mill is equipped with a thickener mill stator 9, a thickener mill rotor 10, a thickener mill handle 11, and a thickener mill impeller 12.

[0017] In this embodiment, the grinding mechanism 8 is a standard colloid mill in the prior art, which does not involve any innovation or improvement. Its standard function is simply applied here to complete the crushing and conveying of the thickener. In specific application within this operating system, it is as follows: After the material enters the thickener mill chamber of the colloid mill through pipe 71 below the premixing tank 6, the high-speed rotation of the thickener mill rotor 10 creates an extremely narrow gap between it and the fixed thickener mill stator 9. Within this gap, the material is subjected to strong shearing force, mechanical friction, and high-frequency impact force. Simultaneously, thanks to the toothed groove structure designed on the surfaces of the stator and rotor, the material particles are further broken down, dispersed, and dissolved, thereby achieving pulverization and uniform mixing.

[0018] The thickener mill handle 11 is used to adjust the grinding particle size: the stator 9 of the thickener mill is moved axially through a threaded rotation mechanism to control the working gap between the stator and rotor. The smaller the gap, the stronger the crushing effect and the finer the resulting material particles. This adjustment method is simple in structure and easy to operate.

[0019] A thickener mill impeller 12 is provided at the rear end of the colloid mill. It rotates at high speed coaxially with the rotor and forms a pumping effect under centrifugal force. The fully crushed and dissolved material is continuously transported to the colloid storage tank 13 through the pipeline 72 connected to the top of the colloid mill, realizing the continuous operation of material mechanical processing and transportation.

[0020] Example 3 The difference between Example 3 and Example 1 or 2 is that: 1) The premixing tank 6 is equipped with stirring blades, which are located at the bottom of the tank near the discharge port; 2) The agitator blades are inclined turbine type.

[0021] In this embodiment, the pretreatment system for dissolving high-viscosity thickener includes a feeding auger, a premixing tank, a thickener mill, a liquid storage tank, and connecting pipes. The material enters the feeding auger through the powder feeding port. The motor drives the feeding auger to operate, conveying the material to the premixing tank. Simultaneously, the valves of the stirring and water replenishment pipes are opened. The material is transferred to the horizontal thickener mill through the connecting pipe at the bottom of the premixing tank. The rotor inside the thickener mill rotates at high speed, and the undissolved agglomerated material collides and rubs between the rotor and the stator, breaking up the agglomerates and dissolving them. The impeller inside the thickener mill rotates at high speed, transferring the fully dissolved liquid to the liquid storage tank through the pipe at the top of the thickener mill.

[0022] High-viscosity or particulate materials tend to adhere to the bottom of the tank and near the discharge port. The bottom blades act as a "scraper" during stirring, helping to push the material towards the discharge port and continuously stirring during the discharge process to prevent the discharge port from being blocked.

[0023] Example 4 The difference between Example 4 and Examples 1, 2, and 3 is as follows: 1) Water supply pipe 4 is located at the top of the premixing tank.

[0024] The downward water flow impact force generated when water enters through the water supply pipe helps to drive the premixed material into the subsequent grinding mechanism. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
