What are the applications of magnets in food and agriculture?
Food processing: Magnets play an important role in food processing. For example, in grain processing, magnets are used to remove impurities such as metal flakes and stones to ensure the purity and safety of food. Magnets can also be used to remove iron flakes from food to prevent oxidation of the food.
Aquaculture: The application of magnets in aquaculture is mainly to remove metal impurities in magnetized food. By placing magnets on the feed conveyor or using a magnetic filter unit, metal particles can be prevented from entering the animal's digestive system, thereby improving the animal's health.
Crop planting: Magnets also have certain applications in crop planting. Magnets can help improve the quality and nutrient content of soil and promote the growth of crops. By adding magnets to irrigation water or burying them in soil, soil fertility can be increased and crop yields improved.
Water treatment: Water quality is one of the important factors in agricultural production. Magnets can be used to treat metal ions and other pollutants in agricultural water. By using magnets to attract substances and remove them from the water, water quality can be improved and crops protected from pollutants.
Agricultural machinery: Magnets are also widely used in agricultural machinery. For example, in grain harvesters, magnets are used to attract and separate metal impurities, preventing them from causing mechanical failure. Magnets can also be used to remove iron filings and metal fragments from agricultural machinery, keeping machinery running properly.
High-efficiency fertilizer: Magnets can be used to make high-efficiency fertilizer. By adding magnets to common fertilizers, you can enhance the fertilizer's nutrient content and make it easier for plants to absorb. Magnetic fertilizers can also reduce fertilizer loss and pollution, and improve crop utilization.
Storage and packaging: Magnets are widely used in the storage and packaging of food and agricultural products. Magnetic materials can be used to make the closure of food packaging bags to ensure that the packaging bags are completely sealed. Magnets can also be used to store and hang props such as knives and tools to improve work efficiency and space utilization.
To sum up, magnets have many applications in food and agriculture. They can be used to remove impurities from food, improve soil quality, improve water quality, clean farm machinery, make high-efficiency fertilizers, and for storage and packaging. These applications can improve the quality and efficiency of food and agricultural production, and ensure food safety and hygienic quality.
"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
