The general rule for estimating how much desiccant is needed, is that 1.2 units of desiccant will protect up to 1 cubic foot of volume (space).
How do I calculate how much desiccant I need?
Can you use too much silica gel?
How much moisture can 1g of silica gel absorb?
adsorbs up to 30% of its weight in moisture.
How long does a packet of silica gel last?
How do I choose silica gel?
Know the environment: In order to select an appropriate desiccant, it is important to know the conditions surrounding the shipment and storage of the product; the extremes of temperature and relative humidity to which the product will be exposed and the average duration of such exposures.
How do you store silica gel?
Store Silica Gel in an airtight container for long term storage so that they don’t absorb moisture from the atmosphere when they are not in use. Remember to recharge your Silica Gel crystals often enough, and your camera equipment should last a very long time.
Are all desiccant packs food safe?
We wanted to know if including silica gel packets would harm our food or us. Silica gel is food safe. Food-grade silica gel desiccants are safe to use to remove moisture from food. Silica gel will not change or permeate the food it’s packed with.
Can you microwave silica gel?
It has come to my attention that people aren’t aware that you can microwave your desiccant to remove the moisture from it. I put them in for a minute at a time, then flip them, then do another minute. Be careful when flipping them as it will be hot. Thankfully you can grab the edge of the packet and be fine.
How can I reactivate my silica gel?
Silica Gel can be restored to its original state by heating it in an oven to 120 °C (248 °F) for 1–2 hours. Once it is restored, it will return to its original color; either orange or blue depending on its type. Silica Gel gets saturated with moisture rather quickly when there is a high level of humidity in the air.
Can you reuse oxygen absorbers?
Oxygen absorbers are not reusable. As 21% of air is oxygen, it’s not good to open your bag of food with oxygen absorbers as oxygen will be reintroduced to your stored food.
How do I reactivate my desiccant bag?
Heat the oven to a temperature between 175 degrees and 200 degrees Fahrenheit. Place the pan of silica gel in the oven and allow it to bake for 15 minutes. The heat in the oven draws the moisture out of the silica gel, reactivating the drying agent.
Is blue silica gel safe?
Do not use blue silica gel around food since the cobalt chloride is poisonous. Orange silica gel has methyl violet which is capable of changing from orange to green, or orange to colorless. It is also toxic and potentially poisonous, even though it does have some medicinal merits.
What is blue silica gel used for?
Blue Indicating Silica Gel Typical Applications
compressed air dryers, gas drying, breathers, and in packaged goods.
How do you reactivate flower drying crystals?
To reactivate the Flower Drying Art™ Silica Gel, place in a shallow pan in an oven heated to 250 degrees Fahrenheit for no less than 5 hours. The pink and white crystals will return to a blue hint when it is ready to be used again.
How long does it take for oxygen absorber to work?
How Long Does it Take For the Oxygen Absorbers to Work? Oxygen Absorbers become warm to the touch when they are working. They take about 4 hours to achieve their rated maximum absorption.
How do you reuse silica gel?
Silica Gel can be restored to its original state by heating it in an oven to 120 °C (248 °F) for 1–2 hours. Once it is restored, it will return to its original color; either orange or blue depending on its type. Silica Gel gets saturated with moisture rather quickly when there is a high level of humidity in the air.
What can I do with old silica gel packets?
- Toss them in with your yoga mat.
- Use them to dry out a drenched phone.
- RELATED: Don’t ditch those coffee grounds! Use them around your home and garden.
- Stash a few of these packets in with important documents and photographs.
- Extend the life of razor blades.

Is it safe to heat silica gel?
Saturated Silica Gel can be reactivated by placing in an oven at 150°C (300°F) for up to 3 ½ hours or until the blue color is restored, Note: heating above 162°C (325°F) can damage the gel and render it unable to absorb moisture. Gel desiccant can also be reactivated using a microwave oven.
Why are my oxygen absorbers hot?
If it gets real hot and uncomfortable, it is in full out working mode and has probably been exposed to the air for too long to be usable. In this case it may also start to feel hard and brick like. Toss it. Oxygen absorbers themselves have a limited shelf life, even when sealed.
Why are my oxygen absorbers heating up?
When oxygen absorbers are in use, they heat up – if you were to remove one that’s activated from your jar or container of dry goods while it’s doing it’s thing, it would actually be warm to the touch. They work on the same chemical reaction process as disposable hand warmers.
