Description

Technical Field

[0001] This utility model relates to the field of iodine addition technology, and more specifically, to a device for uniformly adding iodine to seaweed. Background Technology

[0002] Iodine is one of the essential trace elements for the human body, playing an irreplaceable role in the synthesis of thyroid hormones, the development of the central nervous system, and the regulation of energy metabolism. To prevent iodine deficiency disorders, many countries and regions have implemented iodized salt policies. Seaweed iodine, due to its natural source and good bioavailability, has gradually become one of the important raw materials for iodized salt. In the production process of seaweed iodized salt, seaweed iodine extract must be evenly added to the salt, ensuring that the iodine content meets national standards (usually 20-30 mg / kg), while avoiding localized excessive or insufficient amounts to guarantee product quality and food safety.

[0003] Traditional methods of adding iodine to seaweed primarily rely on static spraying combined with mechanical agitation. Typical equipment includes an open-top mixing tank, a fixed top spray system, and bottom agitator blades. During operation, the iodine solution is pumped to the top nozzles and sprayed onto the salt bed in a dripping or linear stream manner, while the bottom agitator performs radial or tangential stirring at a low speed (typically below 100 rpm) to attempt to mix the iodine solution with the salt particles. However, this method has significant drawbacks: First, the spraying uniformity is poor. Fixed nozzles have limited coverage, causing iodine solution to concentrate in the central area of ​​the mixing tank, resulting in a "wet nucleus" on the salt bed surface, while the edge areas are insufficiently sprayed. Salt particles have poor flowability, especially in high humidity environments, easily clumping together, further hindering the diffusion of iodine solution. Experiments show that the coefficient of variation (CV) of iodine content in iodized salt produced using traditional methods can be as high as 15% or more, far exceeding the industry ideal standard (≤5%).

[0004] Secondly, the stirring efficiency is low. Although the bottom stirrer can move the salt particles, its low-speed rotation and short blade design make it unable to effectively break up the temporary agglomerates formed after the salt particles come into contact with the iodine solution. The iodine solution mainly exists in the form of adsorption on the surface of the salt particles. If it is not dispersed in time, local areas may experience excessive iodine concentration (even exceeding 50 mg / kg) due to droplet aggregation, while other areas may be below the addition standard. In addition, low-speed stirring easily creates "dead zones"—especially at the edges and bottom corners of the tank—further exacerbating the unevenness.

[0005] Third, iodine solution loss and process contamination. In traditional spraying, iodine solution is exposed to air for a long time, especially the organic iodine components in seaweed iodine, which are easily oxidized or volatilized, resulting in a decrease in the actual iodine content. Some equipment attempts to increase the number of nozzles or increase the pump pressure to expand the coverage area, but this may cause the iodine solution to atomize and adhere to the tank wall or equipment surface, resulting in raw material waste and cross-contamination.

[0006] To improve uniformity, the industry has tried various improvement solutions. For example, high-speed shear mixers (such as turbine or ribbon mixers) are used to enhance mixing intensity, but high-speed rotation easily generates heat, accelerating the decomposition of iodine solution and significantly increasing energy consumption. Another solution is to use airflow spraying, atomizing the iodine solution and then conveying it to the salt bed through airflow. However, the atomized droplet size is difficult to control; droplets that are too fine are easily carried away by the exhaust system, while droplets that are too coarse settle too quickly, neither of which can achieve uniform distribution.

[0007] Furthermore, the physical properties of salt (such as particle size distribution, moisture content, and bulk density) further increase the difficulty of uniform addition. In recent years, in order to improve the flowability of salt, some products add anti-caking agents (such as potassium ferrocyanide). These additives may change the surface tension of salt particles and affect the adsorption behavior of iodine solution, and traditional equipment is difficult to adapt to such changes.

[0008] In summary, existing seaweed iodine addition equipment has significant shortcomings in terms of uniformity, efficiency, and adaptability. There is an urgent need for a new type of equipment capable of achieving spatially uniform distribution of iodine solution, efficient mixing, and process control, while simultaneously reducing iodine loss and contamination risks.

[0009] The iodizing device for salt production described in Chinese utility model patent CN218516539U is characterized by comprising: a mixing tank with an inlet at the top and an outlet on the lower side wall; a guide block installed inside the mixing tank, the guide block being conical and located at the upper part of the mixing tank, with the outer wall of the guide block forming a channel for salt to pass through between the inner wall of the mixing tank; a first conveying pipe, one end of which passes through the axis of the guide block and extends below the guide block; and multiple nozzles installed on the outer wall of the first conveying pipe and connected to the first conveying pipe, the multiple nozzles being evenly distributed along the circumference of the first conveying pipe, the nozzles being located in the mixing tank and below the guide block.

[0010] Although the conical guide block enables the salt to fall along the cylinder wall in a dispersed manner, the salt distribution is uneven due to the influence of the feeding angle and initial velocity. Furthermore, the device cannot effectively handle salt lumps because salt is prone to clumping, which will seriously affect the effect of the subsequent iodization process. At the same time, larger salt lumps are easy to get stuck between the guide block and the inner wall of the cylinder, blocking the falling channel and requiring frequent manual maintenance of the device.

[0030] This invention proposes a device for uniformly adding iodine from seaweed.

[0031] The following embodiments will provide a detailed description of the seaweed iodine uniform addition device of this application.

[0032] Example 1: like Figure 3 As shown in the figure, this embodiment proposes a seaweed iodine uniform addition device, including: a tank body 1 with an internal cavity; a stirring mechanism 2, which is located at the bottom of the tank body 1 and coaxial with the tank body 1; a spraying mechanism 3, which is coaxially located inside the tank body 1 with the stirring mechanism 2; and a vibrating plate 4, which is coaxially located at the top opening of the tank body 1. The tank body 1 is made of 316 stainless steel, which is particularly suitable for long-term storage, high humidity environments, or food and pharmaceutical grade requirements. It has the strongest resistance to iodine and chloride ion corrosion, and its inner surface is preferably mechanically polished or electrolytically polished. A smooth surface can reduce the adhesion of salt particles and moisture, making it less likely to form corrosion initiation points and easier to clean. During operation, salt is continuously and uniformly conveyed to the top of the device and falls onto the upper surface of the vibrating plate 4. Under the vibration of the vibrating plate 4, the salt particles fall evenly from all sides of the vibrating plate 4, are evenly sprayed with iodine solution at the spraying device 3, and finally fall to the bottom of the tank. The stirring mechanism 2 stirs the salt after the iodine spraying to achieve further uniform fusion of salt and iodine. The stirring mechanism 2 is divided into three layers, which are L-shaped stirring rods of different lengths arranged circumferentially and staggered at different heights to achieve uniform stirring of the salt in the entire bottom of the tank. Example 2: This embodiment is a further improvement based on Embodiment 1. like Figure 3As shown, in this embodiment, the spraying mechanism 3 includes: a pump 31 for providing power to the spraying mechanism 3; a delivery pipe 32 for delivering iodine solution; and a nozzle 33 rotatably connected to one end of the delivery pipe 32. One end of the nozzle 33 is provided with an input pipe 331 connected to the delivery pipe 32, and the other end of the input pipe 331 is connected to a distributing chamber 332. The distributing chamber 332 is circumferentially provided with several output pipes 333. One end of each output pipe 333 is connected to the distributing chamber 332, and the other end is located in a corresponding circumferential opening on the outer surface of the nozzle 33. The centerline of the end of the output pipe 333 away from the distributing chamber 332 forms a certain angle with the radial direction of the nozzle 33. Both the stirring mechanism 2 and the bottom center of the tank 1 are provided with through holes, through which the delivery pipe 32 passes. The upper end of the nozzle 33 is provided with a conical raised slope. The delivery pipe 32 extends from the bottom of the tank 1 through the axis of the stirring mechanism 2 into the tank 1. It does not interfere with the stirring mechanism 2 and is not affected by the vibrating plate 4 located at the top of the tank 1. The end of the nozzle 33 that sprays iodine solution has an angle with the axial direction of the nozzle 33, so that the reaction force generated when the iodine solution is sprayed does not act entirely on the center of the nozzle 33. Because the nozzle 33 is rotatably connected to the delivery pipe 32, the nozzle 33 will rotate around its axis under the drive of the iodine solution's reaction force, achieving 360-degree uniform spraying of the iodine solution. Furthermore, due to the rotation of the nozzle 33, when the iodine solution delivery stops, inertia will cause the nozzle 33 to continue rotating for a period of time, flinging out the iodine solution inside the nozzle 33 and preventing the iodine solution from solidifying and clogging the nozzle 33. The nozzle 33 has a conical protrusion at its upper end, allowing salt to slide off and preventing salt from accumulating on the nozzle 33. Example 3: This embodiment is a further improvement based on any of the above embodiments. like Figure 1-3 As shown, in this embodiment, a support 11 is provided on the outside of the barrel 1, and the vibratory plate 4 is mounted on the support 11 via a connecting shaft 5. By vibrating the connecting shaft 5 through a vibration motor, the vibration of the vibratory plate 4 can be achieved through vibration transmission. Example 4: This embodiment is a further improvement based on any of the above embodiments. like Figure 1-3 As shown, in this embodiment, a temporary storage tray 6 is also provided on the support 11, located between the vibrating plate 4 and the support 11, to control the amount of salt flowing into the seaweed iodine uniform addition device per unit time. The temporary storage tray 6 is cylindrical, with its walls extending outward at a certain angle to form a funnel shape, and has holes at the bottom. The salt is first transported to the temporary storage tray 6 and accumulates, achieving uniform salt flow and slow leakage onto the vibrating plate 4 at a certain speed. This avoids the uneven distribution and inconsistent falling speed that would occur if the salt were directly transported onto the vibrating plate 4. Example 5: This embodiment is a further improvement based on any of the above embodiments. like Figure 3 As shown, in this embodiment, the upper surface of the vibratory plate 4 is provided with a conical slope. This allows the salt particles to slide off from around the vibratory plate 4 more effectively during vibration, rather than remaining on the vibratory plate 4.

[0033] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
