How Silica Gel Deal with Moisture Problems in Drying flower Industries

13, Mar 2020

Gone are the days, when one dried aesthetically beautiful flowers inside their books or diaries. We become so enthralled by the beauty of some flowers that we want to preserve them before they wilt and die. But does a flattened flower appeal you as much as a fresh and upright flower? We bet it doesn’t. In this article, we will discuss a marvellous technique used in the flower industries in preserving and drying flowers using silica gel.

As you already know, silica moisture absorbing packets are an excellent desiccant moisture absorber. Generally, the desiccant used of flower drying is made by combining a mixture of blue indicating silica gel and white non-indicating silica gel.

How to use silica gel for drying flower?

Ensure that the petal of the flowers that are chosen for the drying process have no water in them. An airtight container is taken and silica gel for drying flowers is placed at the bottom of them to hold the flower stem. Before placing the flowers, their stems must be trimmed. Flowers are then placed upright above the drying agent silica gel. Long flowers can be laid as such whereas flat flowers must be placed facedown. The silica gel is gently poured over the flowers. It is ensured that each petal is covered in silica gel for a perfect and intact shape of flowers post the drying process. The silica gel is poured until the flower layer is completely covered.

Next, the air-tight container is sealed and moved to a secure and stable place without tilting the content. The time taken for the drying process depends on the type of flower. It may take up to 6days or even more in some cases.

Firstly, the top of the air contained in gently. Next, the silica gel content is gently poured out until the flower layer begins to show up. Now the flowers are removed one by one and gently shook to remove any silica gel residuals. Once all the flowers are taken out, for long-term storage purposes, a new air-tight container is taken and a thin layer of the drying agent silica gel is placed at the bottom. The dried and intact flowers and gently placed over the silica gel layer inside the storage container and sealed for future use.

This silica gel flower drying process is also known as embedded drying. Flowers generally used in this method include baby’s breath, bachelor’s button, cosmos, dahlia, daisy, rose, pansy, etc.

Advantages of silica gel Desiccant for flower drying or embedded drying:

  • Maintenance of the original shape.
  • Preserve and dry very delicate flowers.
  • Overcoming Petal shrinkage problems.

Depth Guide For Indicating Silica Gel Orange vs. Silica Gel Blue

09, Mar 2020

Silica gel is a widely utilized and highly popular desiccant used in a variety of industrial and daily life applications. Featured with small-sized pores, silica gel allows moisture or water vapors or impurities to peep through it leaving behind pure substances. Among its other counterparts, Silica gel has gained popularity due to its larger surface area thus encouraging faster and efficient moisture adsorption and saturation indicating property. In this article, we will discuss the indicating property of silica gel and its two types.

Indicating silica gel have this innate ability to notify the saturation level by the color transition. There are basically two types of indicating silica gel: Silica gel orange and Silica gel blue.

Silica Gel Orange

This color-changing silica gel is made of alumino-silicate. They are eco-friendly and are used in various applications involving the prevention of moisture damage in goods and other stuff. Silica gel orange indicators are heavy metal-free, non-toxic and affordable.

When dry it has its industry-made orange color, but as it gets saturated the color of the silica gel gradually changes to green color. This happens due to the presence of methyl violet. The indicating property becomes a great way of notifying when one needs to replace or regenerate the desiccants for the maintenance of constant operation.

There are silica gels that turn from orange to colorless upon saturation. Orange to green silica gel is available in the form of hard round or spherically shaped beads.

Silica Gel Blue

 Just as Silica gel orange supports visual moisture control, silica gel blue too supports the same. The only difference stands are in its color change. When moisture-free, this desiccant displays the color blue. Upon trapping moisture, at first it turns into light blue color. 

As the moisture content raises and reaches a saturation level, this blue colored silica gel turns into pink. Now, it indicates that its time for the regeneration process. The color transition happens due to the chemical compound called cobalt chloride, a heavy metal salt. The indicating property is imbibed in these desiccants by washing them with a concentration of cobalt salt.

Silica gel blue is banned in some European countries due to its toxicity. They are available in the market in the form of beads and crystals.

Be it orange to green silica gel or blue to pink silica gel, both are equally great performers and used widely in numerous applications such as transformer breathers, air dryers, goods packaging, electronic packaging, pharmaceutical packaging, diagnostic kits packaging, etc.

Silica Gel For Dehumidification Process

26, Feb 2020

Desiccant dehumidifiers are highly-effective in removing moisture or water content from the atmosphere. Silica gel is an efficient dehumidifier. In this article, we will discuss the application of silica gel for the dehumidification process.


Dehumidification is the process of removing water or moisture from the room with the evaporative cooler. Removal of the moisture is important to keep the products intact and long-lasting. Desiccant dehumidifiers are a cost-efficient way of controlling the moisture levels, removing odor and micro-organisms from the air.

Silica gel dehumidifier

Being one of the most effective adsorbents and desiccant, silica gel is used in various industries for different applications. Silica gel dehumidifiers are devised such that, the air to be processed, will pass through a bed of silica gel crystals. The silica gel desiccant dehumidifiers will adsorb the water in this air current. Then the processed, less humid air will be allowed to move out of the installation. Blue and white crystals of silica gel are perfect desiccants for protecting the products and systems from corrosion, condensation, mildew and other damaging effects.

Silica gel has a color-changing property. This enables the identification of desiccant upon saturation. For regenerating the silica gel, a hot air current allowed through the gel bed. The hot air will then remove the water from the silica gel, which is at a lower temperature. This air will be directed outside the device or can be directly let to be dehumidified by passing through the regenerated silica gel bed. Both the air currents, the one to be processed at normal temperature, and the one for reactivating the silica gel at elevated temperature, are separated by seals and the entire process is designed in an enclosed device.

Perks of using Silica gel desiccant dehumidifier

  • High performance
  • DMF free
  • Safe and non-toxic
  • Indicating properties
  • Cost-effective and economical

Silica gel desiccants are available in packets, pouches, or in bulk quantity which gives the best possible outcome based on their exact use. The silica crystal dehumidifiers are applied for individual rooms in your home, gun safes, marine and RV applications; they can absorb environmental moisture until they have the full capacity.

A Complete Guide on Silica Gel and How to Differentiate a White, Blue and Orange Silica Gel

26, Feb 2020

Silica gel is one of the highly efficient and most commonly used desiccants. These are typically found in small “beads” form, are an amorphous form of silica (SiO2 xH2O) that are highly porous. Silica gel works well at ambient temperature that can go up to 105 °C. But as the temperature goes above 105 °C, these desiccants slow down and expel its moisture back into the atmosphere. It has the power to absorb up to 40% of its weight in water.

There are two types of silica gel; Indicating and non-indicating. Indicating silica gel are the ones that aid in the rapid detection of moisture saturation by changing the color. Thus, indicating the need for recharge or replace. Indicating silica gel comes in two colors; Orange and Blue. Whereas non-indicating silica gel is white in color and doesn’t provide a way of determining the moisture saturation levels. In this article, we will build a deeper understanding and differentiate a white, blue and orange silica gel.

White Silica Gel

 In silica gel white, the particles are not impregnated with any indicating agent. When moisture-free these beads or crystal appear to be transparent. Upon moisture saturation, they turn milky or hazy white. This is the most commonly used desiccant for commercial purposes and is used in compressed air dryers and to protect vitamins, electronics, pharmaceutical products, etc. from moisture.

Orange Silica Gel

 In silica gel orange, the particles are impregnated with an indicating agent called methyl-violet that gives the color orange to it. Once these beads or crystals reach the maximum adsorption capacity, the orange color turns into green. Orange silica gel is non-toxic and eco-friendly. It finds application in compressed air dyers, breathers, non-consumable packages goods.

Blue Silica Gel

In silica gel blue, the particles are impregnated with an indicating agent called cobalt chloride. The cobalt chloride gives these bead/crystals a deep-blue color that upon reaching adsorption capacity changes into pink color.

Food Grade Silica Gel – Composition and Uses

26, Dec 2019

In order to protect foods from contamination, this mainly comes from moisture or the presence of other toxic gases that may create an odor that is very unpleasant, silica gel desiccant is one of the most favored absorbing agents known.

It is important to protect the shelf life of foods that are packed and must retain their original properties or freshness for a long duration of time. Silica gel is known to be a key absorbent of unwanted atmospheric hazards.

The Composition of Silica Gel

One of the most important features of silica gel is that it is porous in nature and granular in form. It is made from sodium silicate that is transformed into silica dioxide, which is replaced by the word ‘gel’. It is also known to be a very hard and resilient mineral that attracts moisture in a big way.

It is commonly seen in a bead form and packed in small packets of Tyvek paper that permit the interaction of moisture and silica gel. It is a very popular desiccant. On account of its properties, it is strongly recommended to not be consumed at any cost. Every packet carries this warning.

The Versatile Uses of Silica Gel for Food Packaging

Humidity is one of the biggest culprits responsible for the contamination of foods. Fortunately, silica gel has this huge advantage of absorbing about 40 % of moisture more than its own weight and size. These packets come in different sizes depending on the volume of food products that need protection.

silica gel desiccant packets

Most silica gel sachets are packed in a suitable material that promotes the absorption of moisture and other harmful elements that can affect the food. Generally, it is made from Tyvek or polyester fabric. The other important consideration of using silica gel is that it can be regenerated, or can be used multiple times. The only requirement, in this case, is to heat it to a precise temperature (about 250*F for about 2 hours) to release all the unwanted stored substances in its pores.

Especially in the case of Isomalt and cooked sugar that easily absorbs moisture, silica gel is the perfect choice to preserve their longevity. These products are especially known to get sticky in the presence of moisture. Such properties and features make silica gel an ideal choice for keeping products free from moisture.
