Description
Technical Field

[0002] Food additives are synthetic or natural substances added to food to improve its quality, color, aroma, and flavor, as well as for preservation, freshness, and processing needs. During food production, food additives must be accurately and quantitatively transported from storage to processing to achieve uniform mixing with other ingredients and meet precise production process requirements for additive dosage and timing. Potassium sorbate is a preservative used in food additives, primarily for inhibiting mold. It exists in powder form at room temperature.
[0003] In the prior art, potassium sorbate food additives are typically transported using pneumatic conveying, where the powder is propelled by airflow. Without moving parts within the pipeline, this prevents contamination of the additive by lubricants, metal wear particles, and the like. Due to the high airflow velocity, food additives are prone to inertia impacting the inside of the pipe corners, forming deposits and remaining there. This requires workers to regularly dismantle the pipe corners to clean any residual food additives, which is cumbersome. Furthermore, the narrow space in the pipe corners makes cleaning inconvenient, time-consuming, and inefficient.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. When the present invention is used, when the food additives in the transport pipeline are transported to the transport elbow by the dynamic conveying equipment by air flow, the super-hydrophobic coating of super-hydrophobic coating film effectively reduces the adhesion residue of food additives. Magnetostrictive vibrator produces high-frequency ultrasonic vibration, is transferred to thin piezoelectric vibrating membrane by the transfer hole of titanium alloy coupling block and porous gradient structure, produces high-frequency deformation, and is transferred to super-hydrophobic coating film, strengthens contact vibration, directly applies shearing force and peeling force to the powder food additive attached, makes it fall off from super-hydrophobic coating film inner wall, avoids powder additive adhesion residue. Under the effect of bend pipe anti-residue mechanism, adopt magnetostrictive vibrator → titanium alloy coupling block → thin piezoelectric vibrating membrane three-stage transmission, form the energy chain of " high energy input+precision inside output ", all have desorption effect to different particle size powders, make anti-residue effect greatly improved.
[0019] 2. When the present invention is used, the micro-vibrator is started to drive the vibrating mesh plate and the breaking frame to vibrate together. When the agglomerated additive moves in the step groove, it hits the step edge and performs the initial crushing. Vibration occurs in the breaking frame, and collision occurs between the bottom of the breaking plate and the memory alloy protrusions, turning the agglomerated additive into powder. Hot air is injected into the breaking plate to heat the memory alloy protrusions, causing the memory alloy protrusions to deform and bulge downward, increasing their height and better contact with the agglomerated additive, further improving the impact crushing effect and adapting to the dispersion requirements of different sticky powders.
[0020] 3. When the present invention is used, the ionization rod is started, and the positive and negative ions enter the discharge cover through the guide cover and the connecting pipe. The ions are divided into multiple small streams through multiple diversion holes and amplification holes, and flow evenly to the bottom of the breaking plate, fully contacting with the vibrating additives, eliminating electrostatic attraction, causing the agglomerates to lose their binding force and automatically disperse. When the ions pass through the middle narrow part and the spiral sheet, the ion flow speed is accelerated, and eddy currents are generated, causing the ions to diffuse downward in a spiral motion, increasing the contact area with the powder and improving the static elimination effect. Under the action of the static elimination component, static elimination is achieved, and the electrostatic clumps are dispersed. With the cooperation of the vibration breaking component, mechanical crushing is achieved, and the clumps that adhere together are broken up, avoiding the agglomeration of additives to the processing link and affecting the food processing effect.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0039] Example 1: Please refer to Figures 1-15 As shown, the present invention provides a technical solution: a potassium sorbate food additive anti-residue conveying and feeding device, comprising a screw conveyor 1 and a quantitative feeder 2 installed at the discharge end of the screw conveyor 1, the bottom end of the quantitative feeder 2 is fixedly connected to a transport pipe 3, one end of the transport pipe 3 is provided with a bend anti-residue mechanism 4, and one end of the bend anti-residue mechanism 4 is provided with a discharge mechanism 5; the bend anti-residue mechanism 4 comprises a transport bend 41, two magnetostrictive vibrators 42 are installed on the outer surface of the transport bend 41, a thin piezoelectric vibration film 43 is provided on the inner wall of the transport bend 41, a super-hydrophobic coating film 46 is provided on the inner wall of the thin piezoelectric vibration film 43, a dielectric groove 44 is provided inside the transport bend 41, a titanium alloy coupling block 45 is provided inside the dielectric groove 44, and multiple There are multiple transfer holes 47, and silicone elastomers 48 are arranged inside the multiple transfer holes 47. The magnetostrictive vibrator 42 transfers the vibration energy to the thin piezoelectric vibration film 43 through the titanium alloy coupling block 45. The thin piezoelectric vibration film 43 drives the super-hydrophobic coating film 46 to produce high-frequency deformation, destroying the adhesion of powdered food additives and causing residual powder to fall off. The titanium alloy coupling block 45 can reduce the energy loss during the vibration transmission process. The multiple transfer holes 47 are arranged in a gradient, and the transfer holes 47 close to the outside of the titanium alloy coupling block 45 are millimeter-level holes, and the transfer holes 47 close to the inside of the titanium alloy coupling block 45 are micron-level holes. The outer surfaces on both sides of the super-hydrophobic coating film 46 are fixedly connected to the inner walls of the two ends of the transport bend 41, and one end of the transport bend 41 is connected to one end of the transport pipe 3 through a flange.
[0040] In this embodiment, when in use, the screw conveyor 1, the quantitative feeder 2, the magnetostrictive vibrator 42, the thin piezoelectric vibrating membrane 43, the micro vibrator 5203 and the ionizing rod 5303 are all electrically connected to an external control system, and the other end of the transport pipe 3 is connected to a pneumatic conveying device. The powdered food additive is transported to the quantitative feeder 2 by the screw conveyor 1, and the food additive is quantitatively proportioned by the quantitative feeder 2 and then transported to the transport pipe 3. At the same time, the pneumatic conveying device is started, and the food additive in the transport pipe 3 is transported to the transport elbow 41 by air flow, and then enters the feeding pipe 51 of the discharge mechanism 5 through the super-hydrophobic coating membrane 46. The powdered food additive is discharged downward through the vibrating mesh plate 5201 and enters the processing link. The clumped food additive is broken up into powder by the cooperation of the vibration breaking component 52 and the static elimination component 53, and is again transported to the feeding pipe 51 for discharge. Under the action of inertia, the powdered food additives entering the transport bend 41 will collide with the inside of the transport bend 41, that is, with the inner wall of the super-hydrophobic coating film 46. The super-hydrophobic inner wall of the super-hydrophobic coating film 46 utilizes the "lotus leaf effect", making the food additives easier to fall off, reducing the adherence and residue of food additives. The magnetostrictive vibrator 42 is activated, converting electromagnetic energy into mechanical energy through the magnetostrictive effect, generating high-frequency ultrasonic vibrations, which are transmitted to the thin piezoelectric vibrating film 43 through the titanium alloy coupling block 45. The thin piezoelectric vibrating film 43 is made of food-grade PVDF and does not affect the food additives. The thin piezoelectric vibrating film 43 is tightly fitted to the inner wall of the transport bend 41, generating high-frequency deformation with vibration, which is transmitted to the super-hydrophobic coating film 46, enhancing the contact vibration, directly applying shear force and peeling force to the attached powdered food additives, causing them to fall off the inner wall of the super-hydrophobic coating film 46 and be transported to the unloading mechanism 5 along with the airflow for unloading. The titanium alloy coupling block 45 is a medium for efficient transmission of vibration energy, which is beneficial to improving the transmission of vibration energy. A plurality of transmission holes 47 are set inside the titanium alloy coupling block 45, and the transmission holes 47 are arranged in a porous gradient structure. Figure 5As shown, the number of millimeter-scale pores near the outside of the titanium alloy coupling block 45 is small, while the number of micron-scale pores near the inner wall of the titanium alloy coupling block 45 is large. The porosity of the transfer pores 47 gradually increases from 5% on the outside to 20%-30% on the inside. The more numerous small pores on the inside, due to the reduced material density and elastic modulus, are more easily excited by ultrasound to produce high-frequency vibrations. The small pore structure concentrates the vibration energy, thereby enhancing the high-frequency excitation of the thin piezoelectric diaphragm 43 and improving the anti-residue effect. The fewer large pores on the outside allow for rapid energy transfer, reducing reflection loss, and ensuring the structural strength of the titanium alloy coupling block 45, avoiding the overall rigidity deficiency caused by the high porosity. The gradient porosity structure gradually matches the acoustic impedance of the titanium alloy coupling block 45 with that of the magnetostrictive vibrator 42 and the pipeline material, reducing interfacial reflection during vibration transmission, increasing the vibration amplitude of the thin piezoelectric diaphragm 43, and effectively stripping away residual additive powder. The transfer hole 47 is filled with silicone elastomer 48, which can fill the air gap in the transfer hole 47, so that the ultrasonic wave can be transmitted more evenly through the "titanium alloy-silicone-titanium alloy" path, reducing energy loss, which is conducive to improving vibration energy transmission, thereby improving the residual powder stripping effect and preventing additives from remaining on the inner side of the transport bend 41. Under the action of the anti-residue mechanism 4 of the bent pipe, a three-level transmission of magnetostrictive vibrator 42 → titanium alloy coupling block 45 → thin piezoelectric vibration membrane 43 is adopted. The outer magnetostrictive vibrator 42 provides macroscopic vibration (driving the overall powder flow), and the inner thin piezoelectric vibration membrane 43 provides microscopic high-frequency vibration (peeling off the nano-level adsorption layer), forming an energy chain of "high energy input + precise inner output", which has a desorption effect on powders of different particle sizes. Compared with the direct action of the traditional outer vibrator, the vibration energy density of the inner wall of the pipeline is greatly improved, and the vibration acceleration of the powder accumulation area on the inner side of the pipeline corner is greatly improved, which greatly improves the anti-residue effect. There is no need for frequent disassembly and installation, and the cleaning work is reduced. This solves the problem that potassium sorbate food additives are easily retained on the inner side of the pipeline corner when transported by pneumatic conveying. The staff needs to regularly disassemble the pipeline corner for cleaning and then install it back, which is more troublesome. In addition, the space of the pipeline corner is narrow, cleaning is very inconvenient, time-consuming, and the work efficiency is low.

Under the elastic support of the first vibrating ring 5205, the second vibrating ring 5207, the elastic pad 5206, the first elastic ring 5208, and the vibration spring 5209, the vibrating mesh plate 5201 vibrates up and down within the vibrating trough 54. The powdered additive passes through the pores of the vibrating mesh plate 5201 and continues to be discharged downward. Agglomerated additives are intercepted above the vibrating mesh plate 5201 and, under the action of vibration, move toward the stepped trough 5202. They then fall through the inlet hole 5216 into the deagglomeration frame 5211. Guided by the guide plate 5219, they are vibrated and dropped below the deagglomeration plate 5308. During the discharge process, the agglomerated additives continuously bounce up and down within the stepped trough 5202, the inner wall of which has a jagged step-like shape. As the agglomerated additives fall, they impact the steps due to gravity, breaking up the large agglomerated additives through the dual action of "impact and shearing," thus achieving initial crushing during the discharge process. The breakup frame 5211 is fixedly mounted on the vibrating mesh plate 5201. The vibration of the vibrating mesh plate 5201 drives the breakup frame 5211 to vibrate up and down on the outer surface of the connecting pipe 5305, and also drives the smooth inclined pipe 5213 to vibrate within the second elastic ring 5214. As the breakup frame 5211 vibrates, the initially broken agglomerated additive inside it bounces up and down, colliding with the bottom of the breakup plate 5308 and the plurality of memory alloy protrusions 5309. This mechanical action again breaks up the agglomerates, causing the agglomerated additive to become powdered again. Vibration causes the powdered additive to fall through the holes at the bottom of the breakup frame 5211 into the discharge hood 5212. Finally, the smooth inclined pipe 5213 transports the broken powdered additive back to the feed pipe 51 for discharge.
[0043] Furthermore, one end of the air inlet pipe 5315 is connected to the hot air supply and exhaust device, which transports the hot air into the air inlet pipe 5315 and the fixed pipe 5314, and then enters the first air injection pipe 5312 and the second air injection pipe 5313, and then inputs the hot air into the scattering plate 5308, and then enters the memory alloy protrusion block 5309 connected to the scattering plate 5308. After being heated, the memory alloy protrusion block 5309 will bulge downward, increasing its protrusion height and better contact with the agglomeration additive, changing the collision angle and frequency of the powder at the bottom of the scattering plate 5308, avoiding the accumulation of powder due to the fixed path, enhancing the powder dispersion effect, and further improving the impact crushing effect to adapt to the dispersion requirements of powders with different stickiness.
[0044] Furthermore, the ionization rod 5303 is activated to generate positive and negative ions, which enter the three connecting pipes 5305 through the guide cover 5304, then enter the discharge cover 5306, and finally flow evenly through multiple diversion holes 5316 and amplification holes 5311 to the bottom of the scattering plate 5308, where they fully contact the vibrating additives. The ions neutralize the surface charges of the powder particles, eliminating electrostatic attraction, causing the agglomerates to lose their binding force and automatically disperse, thus preventing the powder additives from forming lumps due to electrostatic adsorption when being transported in the pipeline, which would affect the subsequent use effect. The structure of the diversion hole 5316 is as follows: Figure 15 As shown, the structure is wide at the top, narrow in the middle, and wide at the bottom. The magnifying hole 5311 is connected to the enlarged hole below the diverter hole 5316, making the entire bottom outlet larger than the top inlet. Ions enter the diverter hole 5316 from the wider inlet at the top, then enter the narrow middle portion, flowing downward along the spiral surface of the spiral blade 5317, and finally are evenly discharged from the magnifying hole 5311 at the bottom. The multiple diverter holes 5316 disperse the ion flow into multiple small streams, causing them to flow vertically downward, reducing lateral diffusion, ensuring full contact between the ions and the powder, and avoiding incomplete static elimination due to turbulent ion flow. When passing through the narrow middle portion and the spiral blade 5317, the ion flow speed can be accelerated and eddy currents can be generated, causing the ions to diffuse downward in a spiral motion, increasing the contact area with the powder and improving the static elimination effect. Under the action of the static elimination component 53, static electricity is eliminated and static clumps are dispersed. With the cooperation of the vibration breaking component 52, mechanical crushing is achieved to break up the clumps that stick together, avoiding the agglomeration of additives to be transported to the processing link and affecting the food processing effect.
[0045] The effect and working principle achieved by its entire mechanism are as follows: powdered food additives are transported to the quantitative feeder 2 by the screw conveyor 1, the food additives are quantitatively proportioned by the quantitative feeder 2, and then transported to the transport pipeline 3. At the same time, the pneumatic conveying device transports the food additives to the transport elbow 41 by airflow, and enters the feed pipe 51 in the blanking mechanism 5 through the super-hydrophobic coating film 46. When the powdered food additives in the transport elbow 41 are transported, the super-hydrophobicity of the super-hydrophobic coating film 46 can effectively reduce the adhesion residue of the food additives. The magnetostrictive vibrator 42 is started to generate high-frequency ultrasonic vibrations, which are transmitted to the thin piezoelectric vibrating film 43 through the titanium alloy coupling block 45. The thin piezoelectric vibrating film 43 generates high-frequency deformation and is transmitted to the super-hydrophobic coating film 46, applying shear force and peeling force to the attached powdered food additives, causing them to fall off from the inner wall of the super-hydrophobic coating film 46, and being transported to the blanking mechanism 5 together with the airflow for blanking. The titanium alloy coupling block 45 and the porous gradient structure of the transmission hole 47 reduce interfacial reflection during vibration transmission, increase the vibration amplitude of the thin piezoelectric vibration membrane 43, and effectively remove the residual additive powder that adheres to it. The micro-vibrator 5203 is activated, causing the vibration mesh 5201 to vibrate. The powdered additive passes through the pores of the vibration mesh 5201 and continues to be discharged downward. Agglomerated additives are intercepted above the vibration mesh 5201 and, under the action of vibration, fall through the stepped groove 5202 and the inlet hole 5216 into the de-aggregation frame 5211. Guided by the guide plate 5219, they are shaken down to the bottom of the de-aggregation plate 5308. At the same time, the vibration of the vibrating mesh plate 5201 causes the deagglomeration frame 5211 to cause the internal agglomerated additive to bounce up and down, colliding with the deagglomeration plate 5308 and the memory alloy protrusions 5309, causing the agglomerated additive to be powdered again and fall into the discharge cover 5212. Finally, the smooth inclined pipe 5213 transports the deagglomerated powdered additive back to the feed pipe 51 for discharge. Hot air is transported to the air inlet pipe 5315 and the fixed pipe 5314, then enters the first and second air injection pipes 5312 and 5313. The hot air is then input into the deagglomeration plate 5308 and then into the memory alloy protrusions 5309. When heated, the memory alloy protrusions 5309 bulge downward, increasing their height and providing better contact with the agglomerated additive. At the same time, the ionization rod 5303 is started to generate positive and negative ions, which enter the three connecting pipes 5305 through the guide cover 5304, then enter the exhaust cover 5306, and finally flow evenly to the bottom of the breaking plate 5308 through multiple diversion holes 5316 and amplification holes 5311, where they fully contact the vibrating additives, eliminate electrostatic attraction, and cause the agglomerates to lose their binding force and automatically disperse.
