TECHNOLOGIES USED IN ETHYLENE HANDLING

Always Fresh

    • Mechanism :
      • Ethylene absorption involves the use of substances like activated carbon, potassium permanganate, or zeolites to physically or chemically bind and remove ethylene from the air.
      • These substances absorb ethylene from the surrounding atmosphere, reducing its concentration and slowing the ripening process.
    • Examples of Absorbents :
      • Potassium Permanganate : Oxidizes ethylene to carbon dioxide and water.
      • Activated Carbon or Zeolite : Traps ethylene gas in its porous structure.
    • Effectiveness :
      • Absorption reduces ethylene levels in a passive way, but it has limitations in how much ethylene it can handle at a time.
      • Over time, the absorbent material can become saturated and lose effectiveness, requiring replacement.
    • Limitations :
      • Finite capacity : Absorbents can become saturated, requiring frequent replacement.
      • Reactive byproducts : In some cases, the byproducts (e.g., CO₂ and water) can affect the environment.
      • Limited efficacy : May not be efficient for high ethylene-producing environments or long-term use.

  • Mechanism :
    • Ethylene conversion involves transforming ethylene gas into a chemically inert or less reactive compound, such as ethylene oxide, using advanced technologies like Silver Nano Technology
    • The conversion process actively changes the chemical structure of ethylene, rendering it incapable of promoting ripening.
  • Example of Conversion :
    • In Vamsa Agri Fresh Keeper, patented Silver Nano Technology catalyses the conversion of ethylene gas into ethylene oxide, which does not contribute to ripening or spoilage
  • Effectiveness :
    • Highly effective, as it actively removes ethylene by converting it into a non-reactive compound
    • Does not depend on the capacity of an absorbent material, making it suitable for long-term use in high ethylene-producing environments.
  • Applications :
    • Ideal for cold storage, transportation, and long-term preservation of high-value or high ethylene-producing produce
  • Advantages :
    • Continuous action : Does not saturate like absorbents.
    • No reactive byproducts : Conversion results in stable compounds that do not impact the environment.
