What significant impact does the Magnetic Liquid Trap have on the food industry under the influence of rare earth policies?

In today's society, the safety and quality of the food industry is one of the most concerned focuses of consumers. Although the adjustment of rare earth policies in recent years seems to be far away from the food industry, it actually has a profound impact on the food industry indirectly by affecting the key components of food production equipment-liquid iron removers. With the slowdown in the growth rate of total rare earth mining control indicators and the implementation of policies such as export controls, the stability of rare earth supply has been affected. This has led to the following problems faced by liquid iron remover manufacturers.

Shock wave to the equipment manufacturing industry: The core magnet of the fluid iron remover relies on rare earth elements (such as neodymium and dysprosium) to build a strong magnetic field. The tightening of policies has led to three major chain reactions:

Cost pressure: Rare earth price fluctuations have caused the cost of high-performance magnetic materials to increase by 30%-50%, squeezing the profit margins of equipment manufacturers

Delivery delays: The raw material procurement cycle has been extended from the usual 4 weeks to more than 12 weeks, affecting equipment delivery plans

Technology forced: Companies are forced to develop hybrid magnets with low rare earth content, or turn to alternatives such as ferrite

Fluid iron remover: Why it is the invisible guardian of food safety

In the viscous slurry of jam and the milky white fluid of milk, ferromagnetic impurities (particle size below 50μm) that are difficult to distinguish with the naked eye pose a fatal threat - 0.1 gram of iron filings is enough to cause the entire batch of products to exceed the microbial standard.

Application pain points in the food industry

Raw material pollution: The detection rate of iron filings from agricultural machinery wear in domestic soybeans and wheat is as high as 120ppm (imported raw materials ≤50ppm)

Processing hazards: welding residues of metal pipes, wear particles of grinder blades

Consequences: 0.1g of iron filings can lead to:

Oxidation and rancidity of fats (iron ions are oxidation catalysts)

Microbial growth (iron filings scratch packaging and cause leakage)

Consumer tooth damage (hard metal fragments)

Working principle of Magnetic Liquid Trap

When liquid raw materials flow through a pipe equipped with rare earth permanent magnets, the device with a magnetic field strength of up to 12,000 Gauss can capture nano-scale iron particles with an efficiency of over 99.97%. This is the embodiment of the irreplaceability of rare earth elements: the magnetic energy product of NdFeB magnets is 10 times that of ordinary magnets under the same volume.

Core mechanism: precision filtration in magnetic field

The essence of fluid iron remover is to use rare earth permanent magnets to build a high-intensity magnetic field to achieve non-contact impurity removal during the flow of liquid food:

Magnetic field strength: NdFeB magnets generate a strong magnetic field of 12,000~15,000 Gauss (equivalent to 24,000 times the earth's magnetic field), which can capture ferromagnetic particles as small as 0.5 microns.

Dynamic capture: When the liquid flows through the magnetic bar array or magnetic pipeline, impurities such as iron filings, welding slag, and metal particles caused by equipment wear are magnetically adsorbed on the pipe wall, and the purified fluid continues to flow.

Key indicators: The iron removal efficiency reaches 99.97% (for impurities with a particle size of ≥50μm), far exceeding traditional filters (90%~95%).

In the context of the continuous adjustment of rare earth policies, liquid iron removers will continue to provide key support for the food industry. If food companies use it well, they can effectively cope with the challenges brought by raw material changes, ensure stable product quality, meet consumers' strict requirements for food safety, and develop steadily in a complex market environment. In addition, with the increasing requirements for iron residue detection in the food field, such as the mandatory requirement for iron residue detection in the new FDA 2025 standard, the market demand for liquid iron removers in the food industry will also increase further.

In the big environment, we should keep abreast of changes in rare earth policies: pay close attention to the adjustment of national rare earth policies, such as the implementation of total mining control, export control and other policies, and make preparations in advance.

Industry standard reference:

China National Standard: GB 14881-2013 mandatory provisions "liquid production lines must be installed with iron removal equipment"

EU Standard: EC 1935/2004 requires metal residues ≤3ppm (baby food ≤1ppm)

Testing and certification: The iron removal efficiency must be verified through the HACCP system, and third-party testing every quarter
