How to dry Desiccant Packs
- Important: Do not use a microwave oven.
- 250 degrees Fahreneit for 6 hours removes roughly 80% moisture.
- 250 degrees Fahreneit for 8 hours removes most moisture.
- 250 degrees Fahreneit for 12 hours removes most moisture from very heavy/stiff packs.
What is the maximum safe temperature for desiccant?
If your desiccant is packaged, particularly if packaged in Tyvek, do not heat it above 250° F (121° C) or you could damage the material. This leaves a fairly narrow temperature window since silica gel will not begin to desorb moisture below 220° F (104° C).
Can You Dry desiccant in the oven?
You can dry silica gel packets or free-flowing silica gel in a standard oven, while you can dry free-flowing, color-changing silica gel in a microwave oven. How long does a desiccant last? The life of a desiccant varies depending on dehumidifying equipment operating conditions.
How to dry desiccant packs?
How to dry Desiccant Packs Check Sta-Dri pouches weekly to see if they need re-charged. When rigid or an increase in weight is noted (over 30%), regenerate in the oven. Important: Do not use a microwave oven. 250 degrees Fahreneit for 6 hours removes roughly 80% moisture. 250 degrees Fahreneit for 8 ...
What are the benefits of desiccant drying?
With desiccant drying, you can increase efficiency in your facility and make your company more energy efficient at the same time. Since these desiccant drying machines provide continuous, closed-loop drying, they allow different sections to work through the drying, regeneration and cooling processes simultaneously.
What temperature do you dry desiccant?
Program the oven at 275°F. Leave the oven door slightly ajar and bake for about 1 ½ hours. View every 15 minutes for change in color; do not overheat, product will darken and become unusable.
What temperature do you reactivate desiccant?
between 221°F to 266°FHow does the reactivation work? As a general rule, saturated desiccant will require a minimum of 4-6 hours at a temperature of between 221°F to 266°F (105°C to 130°C) throughout the entire desiccant bed for the reactivation process to be effective and reduce the adsorbed moisture to less than 2% by weight.
What temperature does silica gel dry at?
200 to 250 FAccording to Dry & Dry producer of silica gel, you should dry for 0.5 to 2 hours at 200 to 250 F in a conventional oven. In silica gel, the physically adsorbed water can easily be removed when kept in an air oven at temperature around 150 degree centigrade temperature for 2-3 hours.
How do you dry out desiccant?
You can do so by pouring the inactive silica gel beads in a thin layer on a baking sheet. You should then preheat the oven to 175 degrees Fahrenheit and bake the beads for 15 minutes. The heat in the oven will draw the moisture out of the desiccant pack, reactivating the drying agent.
Can you overheat silica gel?
Some desiccants are seriously damaged and can release toxic chemicals if overheated. 2. Reactivation should be carried out in a ventilated electric oven.
How do you rejuvenate desiccant?
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.
Does desiccant work at cold temperatures?
Desiccants, however, continue to remove moisture even at 0° F. Drying with a desiccant is an especially effective (and cost-effective) option in an unheated garage, a crawlspace during the winter months, and in unfinished basements.
How do I know if my desiccant is good?
Pull the desiccant beads out and squish them between your fingers. If they are very brittle and crumble upon doing so, they're bad and need to be replaced. Take a styrofoam cup, fill it with about 1 inch of desiccant beads, and pour water on them, just enough to cover them or leave a few above the water.
Do desiccant packs expire?
The silica gel packets – also referred to as desiccant packets or dry packets – do not expire. They are made from a material that will not expire or go bad. But as the silica gel packets are exposed to air and moisture, they will become less effective until eventually, they have totally lost their usefulness.
Can I dry desiccant in microwave?
You can dry silica gel packets or free-flowing silica gel in a standard oven, while you can dry free-flowing, color-changing silica gel in a microwave oven.
How can you tell if silica gel is saturated?
Indicating and non-indicating silica gel can be mixed to help determining when the silica becomes saturated. Silica gel displays its full colour change when it is saturated by holding 8-10% of its weight in moisture; at that point the silica gel should be changed or regenerated.
Is it safe to dry silica gel in microwave?
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.
What is a Desiccant Dryer?
The term “ desiccant dryer ” actually refers to a broader class of drying machines. Some other names for this type of unit are:
What is a Desiccant?
A desiccant is a type of hygroscopic substance that can help induce or sustain a state of dryness within its vicinity. Desiccants are chemically stable or chemically inert, which is what makes them so popular among a variety of industries.
How Does Desiccant Drying Work?
Although there are several different types of desiccant dryers, they all work very similarly. One unique thing about desiccant dryers compared to other plastic dryers is that they use heated dry air to remove the moisture from resin pellets, rather than ambient air.
What are the Advantages to Using a Desiccant Dryer?
Desiccant plastic dryers have many advantages over other types of drying units, including increased efficiency, cost effectiveness and state-of-the-art technology.
So Why Choose a Desiccant Dryer From Shini USA?
Shini USA (a division of Budzar Industries) offers equipment designed for all elements of plastic processing, including a line of drying and dehumidifying equipment.
How to Get Started With Your Desiccant Dryer
Throughout the years, desiccant drying has been a trusted and reliable drying solution for plastic processing companies. A dryer’s compact design and advanced technology make it ideal.
First, Know the Product
Is the cargo highly sensitive to humidity and moisture, or is it fairly tolerant? In other words, how dry does the product need to remain?
Second, Know the Environment
Monitor the temperatures and weather ranges to which the product's storage container will be exposed. The weather has a great effect upon humidity levels inside the container.
Third, Know the Packaging
Packaging can be plastic bags, cardboard boxes, Tupperware, even large Conex storage containers - the list is endless. However, it is the characteristics of the container (the material's permeability, seal type, corrosion resistance, container dimensions, etc.) that are important.
ANY ADDITIONAL INFORMATION?
For those wishing to dive deeper into the above desiccant, Figures 1 and 2 illustrate the adsorption rates (how quickly water vapor is adsorbed) and the adsorption capacities (how much water vapor is adsorbed to reach equilibrium at various relative humidity readings) of the above five common desiccants.
