Moisture resistant particle

VNDRY specializes in wholesale and retail of moisture-resistant nuts and exported to foreign countries

For the transportation of goods as well as for the preservation of goods, moisture-resistant granules are the most effective solution today.

However, to buy moisture-proof beads that suit the product you need to preserve, you need to have the minimum information about each type of desiccant to choose from. will introduce you to some popular types of hygroscopic seeds today for your convenience in selecting and using it.

Common types of hygroscopic seeds

1. Silica gel hygroscopic:

As a result of a chemical reaction, a result of laboratory preparation and mass production into moisture-proof grain products, they are usually transparent or green in color. we have seen it many times, it is often packed into small dehumidifying packages weighing 0.5gr, 1gr, 2gr ... put together with the product to be preserved.
They are composed of dry crystals, capable of absorbing water vapor, with many tiny holes to contain the water vapor they absorb. With transparent white silica granules it will gradually shift to the wet weight after absorbing water vapor from zero when surrounding it; With green silica granules it will gradually transform into dark green and wet solids similar to white silica gel dampers.

These silicagen nuts are often used to preserve non-edible foods such as clothing, electronics, and other goods ....

2. Carbon moisture-proof granules:

Are particles that exist in graphite form, have dry properties and are highly hygroscopic. They usually exist in two forms: round and rhombic, black in color like graphite or brown.
This is a type of moisture-absorbing seed derived from nature, so they are harmless and selected for many applications of edible food products.

As with other types of hygroscopic particles, they are often packed into small packages with nylon or cotton paper covers, on the cracks of tiny pores so that the steam can follow the air into the hygroscopic particles.

3. Particulate soil moisture

It is a kind of hygroscopic grain taken from natural soil in dry form, able to absorb high water, she is made into small particles and then packed into bags to make moisture-proof package.
With the properties of this particle, we find that it is similar to the hygroscopic grain with graphite so it is also applied in preserving food and drink.
However, with two types of seeds that resist moisture and clay, we are less likely to actually get them because they are made from natural materials. So they require a raw material, but the source is not endless, must be imported or transported from where the new material is available. As for silica gel, which can be prepared and produced anywhere, so it is used more widely, we are more likely to encounter it in daily life.
