Learn more below to uncover the incredible practical knowledge about resin dryers.

 What Do You Know About Resin Dryer?

Resin is an organic polymer that is either solid or semi-solid. It is most commonly a synthetic or semi-synthetic chemical compound with high molecular mass and low melting points. You can use it to manufacture various plastic products.

 Resin Dryer

A resin dryer is a piece of equipment you can use to completely dry or remove moisture from your resin material before subjecting them to further processing. There are two types of resin dryers, depending on the drying process. One that utilizes hot air to dry resin and the second one that uses desiccant besides hot air.

Hot air resin dryer works by using ambient air. First, it passes the ambient air through a heating device which makes the air hot. Then this heated air blew through the hopper. The hopper contains resin material. The hot air passing through the resin material takes up the excess moisture if present.

A desiccant resin dryer uses ambient air and a desiccant, which makes it more effective than a hot air dryer. It first removes the moisture by passing the air through the desiccant, which takes up any moisture if present in the air. Thus, completely dried air passes through the heating element and is forced into the resin material filled inside the hopper.

Why does plastic resin need to be dried before processing?

In general, plastic resins are hygroscopic. Hygroscopic means some force of attraction exists, which helps them absorb the moisture from the atmosphere. There are many reasons why plastic resin needs to be dried before processing. Some of the main reasons are as follows:

  • If you do not dry your plastic resin, then the product you will make with it results in deformation or distortion.
  • The finished product will lose its color if any moisture is present.
  • If you don’t dry it properly, it will react with the air, making bubbles on the surface and affecting the product’s surface quality. Air bubbles are inevitable in the casting process.
  • The moisture content within the plastic resin results in the speedy formation or growth of bacteria and molds, ultimately leading to a smell in the product.
  • If the plastic resin contains moisture, it does not offer excellent resistance to abrasion.
  • The excess moisture doesn’t give your plastic product a shiny finish. They have little to no shine.
  • Moisture content affects the strength associated with your plastic resin. This will ultimately affect the quality of the products.

Because of the above-listed reasons, you must make sure it has zero moisture before you process your plastic resin in the plastic industry.

 How to choose the right type of resin dryer for you?

Several things need your attention while purchasing your resin dryer. Some of the primary considerations are as follows:


The materials used in the manufacturing of a resin dryer determine the durability and life associated with your resin dryer.

How Moisture Content Affects the Performance of Resin Dryer?

Understanding how moisture content affects resin dryer performance is the first step toward better visualizing the concept of a resin dryer. The moisture content plays a crucial role in deciding how your resin dryer will perform. If the moisture content of the resin material is too high, it will affect the performance of the resin dryer.

The high moisture content will take enough time to get removed because the heated dry air gets rapidly saturated with moisture, and the air must need to move through the resin material more than twice or thrice or even more.

If the moisture content is within a specific range, the effect will differ. Because then heated air does not need to move through the resin material too often. The drying process reaches quickly.

The higher moisture content will lead to the extended working and load on each of the components of the resin dryer, including the blower, heating element, and desiccant. If you continue drying the resin material with too much moisture content, this will lead to a shorter lifespan of your resin dryer.

What Are the Maintenance Requirements for Resin Dryer?

Maintenance of your resin dryer is the most important practice. If a Resin Dryer has not been adequately maintained or is in a very dirty environment, it will deteriorate faster. Some of the vital maintenance practices that you need to follow are listed below:

The return air and regeneration filters are the two filters that you need to replace periodically. This is because the ambient air has some dirt particles and foreign particles, making these filters get clogged and reducing the resin dryer’s efficiency.

If the desiccant material contains too much moisture, the air passing through will not get its water appropriately removed. Therefore, replacing the desiccant material or removing the moisture from this material as needed is necessary. This will make you operate a desiccant dryer at optimum efficiency.

Clean your resin dryer periodically to avoid accumulating dirt or debris on your equipment. Also, ensure each of the electrical components and wires is in place, find out if the wires have a cut or leak, and timely replace them to avoid any accidents.

Find out if the resin material releases any oil or other contaminant. If yes, you need to add a trap for the plasticizer other this will result in quick filter deterioration.

What Is the Importance of Resin Dryer?

You cannot ignore the importance of a resin dryer. If you want a high-quality end product that makes you stand out in the market, you must invest in a resin dryer.

You can use a resin dryer to dry several types of resins, including phenolic resin, alkyd resin, polyamide resin, polycarbonate resin, silicone resin, epoxy resin, and polyurethane, polypropylene resin, polystyrene resin, acrylic resin.

When polymers are exposed to water or moisture, they can undergo Hydrolysis. This will result in a strong chemical reaction that will break down covalent bonds, which reduces the molecular weight of the polymers. The polymer’s mechanical properties become much weaker, and it starts breaking down.

The resin dryer ensures the proper chain length of polymers. Without this resin dryer, you cannot make the desired products with high-grade quality. Therefore, you need to make sure the resin dries you choose are according to your needs and requirements.

 Can you over dry plastic resin?

No, you cannot over-dry plastic resin. The drying requirements of different plastic resins vary and depend on the chemical bonding they are equipped with. The drying time for each resin material depends on the hygroscopicity and composition of the polymers.

 Over dry resin

There are several reasons why you should not over-dry your plastic resin. These are listed below:


The brittleness of dry plastic resin is its inability to regain its original flexibility after deformation. When you continue the drying process for a longer time and there is less moisture present within plastic resin, this will lead to brittleness. The resin will expand or shrink during the drying process.

Loss in Surface Appearance:

If the surface appears discolored and hazy, the resin is over-dried. This phenomenon occurs under a certain drying temperature or at a significantly higher drying temperature. The surface of the finished product shows pinholes, thin lines, and other damages. This means that the resin has dehydrated to its lowest point, leaving the plastic feeling and looking rough.

You can avoid over-drying by using a moisture analyzer to determine the quantity of moisture content and then proceed with drying effectively. This will increase the material efficiency and result in optimum properties.

What Precautions did You Need to Follow to Operate Your Resin Dryer?

Safety always comes first, so take the time to read and follow the safety guidelines that came with your resin dryer. Whether you are a beginner or well-versed in resin making, it is always important to take extra caution using any drying machine. The main preventive measures are as follows:

When operating the dryer, you need to maintain the temperature within an optimum range. Always turn off the power when cleaning and repairing it. If you find any defective parts, please replace them with the suggestion of our factory.

The drying time of each resin material will depend on the temperature, the thickness of the item you are drying, and other conditions. Consider all these parameters before trying to assess the right drying time.

Make sure to wear protective clothing while handling resin material. The reason is that it might react with your skin and cause an allergic reaction. While placing the resin material, wear hand gloves to prevent the direct interaction of the resin material with your skin.

If you have a breathing issue, wear a respirator while handling resin to avoid the intake of fumes released from resin materials. Wearing goggles is also an effective measure while operating with a resin dryer.

What Operational Parameters Affect the Efficiency of Resin Dryer?

Several operational parameters significantly affect the efficiency of your resin dryer. Some of the main operating parameters are as follows:


Most resin dryers require a specific temperature to operate efficiently. Therefore, temperature changes in the dryer affect the drying efficiency. If the air temperature is high, you can finish up with drying in less time and vice versa.

Moisture Content:

According to the principle of material drying theory, the performance and efficiency of the resin dryer are affected by the moisture in the resin material; that is, by taking off only water in the resin material, one can help achieve a specific goal more efficiently. If the moisture of resin material is high, it takes longer to dry the material completely than the material having less water.

Air Circulation:

It is generally recognized that the efficiency of the resin dryer is related to the air circulation in the drying chamber. However, air motion developed by the fan system will help with better air circulation. Good air circulation can make the resin dryer work well. If there is no moving air in the chamber, the resin’s operating efficiency will decrease a lot.

How portability of the resin dryer facilitates your operation?

The word portability reflects that you can move it anywhere you want. It comes with embedded wheels at the base of the resin dryer, which facilitates the effective movement of your resin dryer. This dryer offers you a compact design.

A portable dryer could be the right choice if you are concerned about space, labor intensity, or other issues. The mobile dryer is the most appropriate equipment for the daily production of products.

It provides an economical, elegant, and convenient choice for daily use. Resin dryers are enormous dryers that need minimum land space to install. It is suitable for applications with demand for short drying time and large-volume production.

How does a honeycomb wheel increase effectivity of the resin dryer?

A honeycomb desiccant wheel works by rotation. It is partly exposed to air on one side and absorbs its moisture. When this side attains maximum water, it rotates and offers the other side having less moisture. This way, it allows you to continue your drying operation without any interruption because you don’t need to change the desiccant too often because of excess moisture.


A honeycomb is made from hexagonal cells that provide thousands of tiny air channels to expose a large surface area to airflow. This design helps air circulate more swiftly and evenly to ensure efficient drying. The honeycomb wheel is the only component which make the performance of your resin dryer extra ordinary.
