Hey there! As a supplier of inside oxygen absorbers, I often get asked about how these little wonders work inside sealed containers. So, let's dive right in and explore the fascinating world of oxygen absorbers.
What Are Oxygen Absorbers?
First off, oxygen absorbers are small packets that are designed to remove oxygen from the air inside a sealed container. They're super useful because oxygen can cause all sorts of problems, like spoilage, mold growth, and oxidation. By getting rid of oxygen, these absorbers help to extend the shelf life of the products stored in the container.
The Science Behind Oxygen Absorbers
The most common type of oxygen absorber contains iron powder. When the iron powder comes into contact with oxygen and moisture in the air, a chemical reaction called oxidation occurs. Here's a simple breakdown of what happens:
-
Initial Reaction: The iron powder reacts with oxygen and water to form iron oxide (rust). This reaction is exothermic, which means it releases heat. The general chemical equation for this reaction is:
[4Fe + 3O_{2}+6H_{2}O \rightarrow 4Fe(OH){3}]
Then, the iron hydroxide ((Fe(OH){3})) further dehydrates to form iron oxide ((Fe_{2}O_{3})). -
Oxygen Consumption: As the iron powder oxidizes, it consumes oxygen from the surrounding air. This reduces the oxygen level inside the sealed container. Most oxygen absorbers can reduce the oxygen level to less than 0.1%, which is extremely effective in preventing spoilage.
How They Work in Sealed Containers
Let's say you have a sealed container with some food items in it. You place an oxygen absorber packet inside the container and seal it up tightly. Here's what happens next:
- Diffusion of Oxygen: Oxygen molecules inside the container start to move around randomly. They eventually come into contact with the oxygen absorber packet.
- Reaction on the Surface: The oxygen molecules react with the iron powder on the surface of the absorber. As the reaction progresses, more oxygen is drawn towards the absorber, creating a concentration gradient.
- Continuous Absorption: The absorber keeps on absorbing oxygen until the oxygen level inside the container reaches a very low level. This low oxygen environment helps to preserve the quality of the food by preventing the growth of aerobic bacteria, mold, and yeast.
Different Types of Oxygen Absorbers
We offer a variety of oxygen absorbers to meet different needs. For example, our YOME - OE is a high - performance oxygen absorber that is suitable for a wide range of applications. It has a long shelf life and can effectively remove oxygen from sealed containers.
Another great product is our Faster Reaction Oxygen Absorber. As the name suggests, it has a faster reaction rate, which means it can quickly reduce the oxygen level inside the container. This is especially useful when you need to preserve products that are highly sensitive to oxygen.
Our Yome - C Double Effect Oxygen Absorbers are also very popular. They not only absorb oxygen but also have a moisture - absorbing function. This double - effect feature makes them ideal for products that are sensitive to both oxygen and moisture.
Factors Affecting the Performance of Oxygen Absorbers
There are a few factors that can affect how well oxygen absorbers work inside sealed containers:
- Temperature: Higher temperatures generally speed up the oxidation reaction, which means the absorber will work faster. However, extremely high temperatures can also cause the absorber to degrade over time.
- Humidity: Some moisture is necessary for the oxidation reaction to occur. If the humidity is too low, the reaction may slow down. On the other hand, if the humidity is too high, it can cause the absorber to clump together, reducing its effectiveness.
- Container Size and Volume: The size and volume of the container matter. A larger container will require more oxygen absorbers to achieve the same low oxygen level as a smaller container.
Applications of Oxygen Absorbers
Oxygen absorbers have a wide range of applications. Here are some common ones:
- Food Industry: They are used to preserve the freshness of dry foods, such as nuts, cereals, and dried fruits. By removing oxygen, they prevent the development of off - flavors, rancidity, and mold growth.
- Pharmaceutical Industry: Oxygen can degrade the quality of some medications. Oxygen absorbers are used in pharmaceutical packaging to maintain the stability and effectiveness of drugs.
- Electronics Industry: Some electronic components are sensitive to oxidation. Oxygen absorbers are used in electronic packaging to protect these components from damage.
