Description

Technical Field

[0001] This utility model relates to the field of food additive processing technology, specifically to a filtration mechanism for food additive production. Background Technology

[0002] Food additives are natural or chemically synthesized substances added during food production, processing, and storage to improve food quality, color, flavor, adjust food structure, or based on processing techniques and preservation requirements. They are widely used in modern food industry, effectively enhancing product performance and extending shelf life. However, during additive production, small amounts of incompletely dissolved particles or impurities (such as raw material fragments and crystals) often remain after stirring and reaction. If the finished product is collected directly through the discharge port, these residues will mix into the final product, leading to insufficient additive purity and even affecting its stability, solubility, and effectiveness, posing potential quality and safety hazards.

[0003] Currently, traditional filtration devices mostly employ static filtration or simple screening structures, such as installing a fixed filter screen in the discharge channel. While this design can intercept some residue, it has the following drawbacks:

[0004] Low filtration efficiency: The filter screen is easily clogged, requiring frequent shutdowns for cleaning, which affects continuous production;

[0005] Limited functionality: It can only achieve solid-liquid separation and cannot simultaneously complete the directional discharge and collection of residues, requiring additional equipment.

[0006] Therefore, there is an urgent need to develop a filtration mechanism for food additive production that integrates dynamic filtration, automatic slag discharge, and efficient collection functions, so as to ensure the purity of additive products and the continuity of the production process. Utility Model Content

[0007] The purpose of this invention is to provide a filtration mechanism for food additive production to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a filtration mechanism for food additive production, comprising a tank, wherein the bottom of the tank is provided with a discharge channel.

[0009] The side wall of the discharge channel is provided with two inclined cylinders, and the center lines of the two inclined cylinders coincide.

[0010] A sealing end cap is detachably installed at the end of the lower inclined cylinder. One end of the filter cylinder is fixedly connected to the sealing end cap, and the other end of the filter cylinder passes through the lower inclined cylinder and is adapted to the inner wall of the discharge channel.

[0011] The upper inclined cylinder has a spiral conveying assembly that can extend into the filter cylinder at its end, and a slag discharge port is provided at the upper end of the side wall of the upper inclined cylinder.

[0012] Preferably, the spiral conveying assembly includes a drive motor disposed at the end of the upper inclined cylinder, the drive end of the drive motor extending into the inclined cylinder and connected to a spiral conveying auger, the spiral conveying auger extending to the inner side of the filter cylinder.

[0013] Preferably, a square locking block is rotatably mounted at the end of the spiral conveyor away from the drive motor, and a locking groove adapted to the square locking block is provided in the middle of the sealing end cover.

[0014] Preferably, the sealing end cap is provided with a mounting base, the outer wall of the mounting base is provided with external threads, and the inner wall of the filter cylinder is provided with internal threads that match the external threads.

[0015] Preferably, the bottom of the tank is provided with a collection box that communicates with the slag discharge port.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a filtration mechanism for food additive production, which, by setting a coaxial inclined double cylinder and a built-in spiral conveying assembly, utilizes the rotation of the spiral conveying auger in the filter cylinder to force the additive solution containing residues to move along the surface of the filter cylinder, thereby achieving dynamic continuous filtration.

[0017] The filtrate quickly seeps into the discharge channel through the pores of the filter cylinder, while the residue is directionally conveyed to the upper slag discharge port by the screw conveyor. This effectively avoids the filter screen clogging problem caused by residue accumulation in traditional static filtration, and significantly improves filtration efficiency and product quality.

[0018] The design of the screw conveyor assembly and the slag discharge port can simultaneously complete the automatic separation and discharge of residues during the filtration process, eliminating the need for machine shutdown for cleaning, ensuring continuous operation of the production line, and reducing the frequency of manual intervention.

[0023] 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.

[0024] Please see Figures 1-3This utility model provides a technical solution: a filtration mechanism for food additive production, including a cylindrical stainless steel tank 1 with a conical discharge channel 2 welded to the bottom. The outlet end of the discharge channel 2 is connected to a food additive finished product collection pipe. Two inclined cylinders 3 are symmetrically welded to both sides of the discharge channel 2, with their axes coinciding. A sealing end cap 4 is fixed to the end of the lower inclined cylinder 3 by bolts. A rubber sealing ring is provided between the sealing end cap 4 and the inclined cylinder 3 to prevent filtrate leakage. A mounting seat 402 is provided in the middle of the sealing end cap 4. The filter cylinder 5 is a stainless steel porous cylinder with a bore diameter set to 0.1-0.5mm according to the particle size of the additive. One end of the inner wall has an internal thread that matches the external thread of the mounting base 402, and it is fixed to the sealing end cover 4 by screwing. The other end of the filter cylinder 5 extends into the discharge channel 2 and has a clearance of ≤2mm with the inner wall of the discharge channel 2 to ensure that the filtrate can only enter the discharge channel 2 through the pores of the filter cylinder 5. A drive motor 601 is installed at the end of the upper inclined cylinder 3, and the shaft of the drive motor 601 extends into the inclined cylinder 3. And connect to the screw conveyor 602; the end of the screw conveyor 602 extends into the interior of the filter cylinder 5, and a square locking block 603 is rotatably installed at the end via a bearing; a square slot 401 is correspondingly opened in the middle of the sealing end cover 4. When the filter cylinder 5 is installed, the square locking block 603 is embedded in the slot 401, restricting the radial displacement of the screw conveyor 602 and ensuring its stable rotation; a slag discharge port 7 is opened at the top of the upper inclined cylinder 3, and the slag discharge port 7 is connected to a pipe through a flange. The end of the pipe is connected to a sealed collection box 8 for centralized temporary storage of the separated residue; In practical use, the additive solution containing residue is injected from the top of the tank 1 and flows into the discharge channel 2 area after stirring. The solution enters the filter cylinder 5 under the action of gravity, and the filtrate seeps into the discharge channel 2 through the pores of the filter cylinder 5 and is discharged, completing the preliminary filtration. The drive motor 601 is started, and the screw conveyor 602 rotates at a speed of 20-50 r / min, pushing the unfiltered residue in the filter cylinder 5 to move upwards towards the tilting cylinder 3. The residue is conveyed to the slag discharge port 7 by the screw conveyor 602 and falls into the collection box 8, realizing continuous solid-liquid separation.

[0025] Specifically, when the filter cartridge 5 needs to be cleaned or replaced, turn off the drive motor 601, remove the fixing bolts of the sealing end cover 4, rotate the filter cartridge 5 in the opposite direction to disengage it from the mounting base 402, and then remove the filter cartridge 5 for replacement.

[0026] In some embodiments, the filter cartridge 5 may be made of polypropylene, which is suitable for filtering acidic and alkaline additive solutions. This can effectively prevent the filter cartridge 5 from being corroded after long-term use and extend the service life of the filter cartridge 5.

[0027] Working principle: When the material is discharged, the drive motor 601 is started and the screw conveyor 602 pushes the unfiltered residue in the filter cylinder 5 to move upwards towards the inclined cylinder 3; the residue is conveyed to the slag discharge port 7 by the screw conveyor 602 and falls into the collection box 8, realizing continuous solid-liquid separation.
