Twin-rotor
lobe pump are multi-functional and bi-directional positive displacement pumps,
produced with fine technology. These products use synchronic rotors, driven by
a pair of synchronic gears in the gear box. Transmitted by the main shaft and
the sub-shaft. The rotors move synchronically in counter-clockwise a
directions, which, consequently, varies the pump capacity and builds up high
vacuum capacity and emission pressure. It is particularly suitable to pump
sanitary medium, high-corrosive and high-viscous medium.
Rotor
pump with water-proff cover: The pump is equipped with a detachable protective
cover for the whole machine, and the material is S.S., it can protect the
motor, coupling and other parts from corrosion during on-site cleaning.
In
the past 30 years, we dedicate to provide the scientific and professional
solutions in fluid field. In the field of complex fluid transportation, our
company's R&D technology, manufacturing technology, application technology is
at the leading position in the world.
Durrex pumps can be widely used in food, consumer chemical, refined
chemical, paper making, chemical fiber, pharmaceuticals, coating, etc. We will
continue to focus on scientific research and innovation, improve the level of
precision manufacturing, and continuously promote the intelligent development of
fluid transportation industry, to create greater value for global users

Current status and development trend of organic trace elements in the feed industry
**1 Foreword**
Trace elements play a vital role in animal health, directly or indirectly influencing enzyme and hormone formation, which affects growth, metabolism, immunity, and reproduction. Although they make up less than 0.5% of feed, their impact is significant. Traditionally, high-copper and high-zinc pharmacological doses were added to achieve functional benefits. However, the use of inorganic sulfates often led to damage to fat-soluble vitamins and intestinal villi, prompting feed companies to seek better alternatives. Organic trace elements, known for their stability, high bioavailability, and ease of absorption, have become a popular choice in recent years.
As an emerging type of organic mineral additive, organic trace elements have gained attention due to their superior performance compared to traditional inorganic sources. From early imported protein chelates to today’s cost-effective single amino acid chelates, the market has evolved rapidly. With the growing demand for safer and more effective feed additives, many manufacturers have entered the market. However, this has also led to confusion among feed producers, as different companies promote varying claims and concepts, making it challenging to evaluate the true value of these products.
This article aims to clarify common misconceptions and provide insights into the evaluation and future trends of organic trace elements. By understanding the science behind them and the current industry challenges, feed companies can make more informed decisions when selecting and using these essential nutrients.
**2 Industry Status**
**2.1 Unclear Concepts of Organic Trace Elements**
Despite years of development, the concept of organic trace elements remains vague in China. This is largely due to the numerous manufacturers who use marketing strategies to differentiate their products, sometimes leading to confusion. For example, some companies classify basic chlorinated salts or fumarates as organic trace elements, which is misleading. In reality, organic trace elements are defined as metal complexes, including amino acid chelates, protein complexes, and polysaccharide complexes. Amino acid chelates, particularly single-form compounds, are the most widely used today. Understanding what a chelate is—essentially a ring-shaped structure formed by a metal ion and an amino acid—is key to evaluating these products accurately.
**2.2 Lack of Reliable Evaluation Standards**
Evaluating the quality of organic trace elements is a major challenge for many feed companies. The lack of consistent national standards, inconsistent testing methods, and outdated regulations contribute to this issue. For instance, even products like ferrous glycinate chelate, which are commonly used, face problems with unclear molecular formulas and questionable testing procedures. Additionally, some manufacturers send samples that differ significantly from the actual product, raising concerns about stability and quality control. These issues highlight the need for more rigorous and standardized evaluation methods.
**2.3 Use Without Proper Guidelines**
Many feed companies add inorganic trace elements at levels higher than recommended, often following outdated guidelines. This practice is driven by cost considerations and the difficulty in assessing biological potency. Organic trace elements, while promising, require tailored usage plans. Some manufacturers lack the necessary research and testing, relying instead on existing formulations. This can lead to improper application and reduced effectiveness. As the market evolves, it is crucial for feed companies to work closely with manufacturers to develop scientifically sound feeding strategies.
**3 Development Trends**
**3.1 Organic Trace Elements Will Gradually Replace Inorganic Ones**
The shift toward organic trace elements is becoming inevitable. Their advantages, such as improved safety, better nutrient absorption, and reduced environmental impact, make them a more attractive option. Unlike inorganic sources, which often contain harmful residues, organic forms are purer and more stable. As technology advances and consumer awareness grows, the demand for organic trace elements is expected to rise, eventually replacing inorganic alternatives in the market.
**3.2 Composite Trace Elements Will Be the Future**
Specialization and efficiency are key in modern feed production. With increasing regulatory requirements and the need for safer, more effective ingredients, feed companies are turning to composite trace element products. These customized blends simplify procurement, reduce storage costs, and improve overall operational efficiency. By outsourcing the formulation of trace elements to specialized manufacturers, feed companies can focus on their core competencies while ensuring the quality and consistency of their products.
**4 Conclusion**
Organic trace elements are no longer just a trend but a necessity in modern animal nutrition. As the market matures, customers are becoming more discerning, demanding not only high-quality products but also comprehensive solutions. Manufacturers must respond by providing scientific evaluations, reliable testing methods, and tailored application strategies. Only by addressing these needs can the industry continue to grow and meet the evolving demands of feed producers and consumers alike.
