Dryer Cabinet:

A dryer cabinet is used to dry raw polymer resources, mainly when working with small quantities of different components or polymers for testing. After tempering, it could be used in polymer molding to improve toughness, remove tension, and improve the quality of plastic products. It can also preheat or dry electronic, electroplating, pharmaceutical, paint, printing, and other products like pollen, tea, or garlic.

If you operate in the plastics processing sector, you know that resin can start collecting moisture from the environment during the procedures.

When do plastics get wet?

Some plastic resins, whether you believe it or not, become wet, not just on the surface, but down deep at the molecular scale. A few plastic resins have polarity, attracting water and forming molecular bonds with the polymer. These are referred to as hygroscopic resins. Non-hygroscopic resins are plastic polymers that do not collect moisture and only get moist on the surface. Even minor moisture levels in hygroscopic resins, measurable with only instruments, can cause quality issues when polymer resins are molded into parts.

How is plastic resin dried?

Dryers with Hot Air or Dryer cabinets are the most common resin dryers. Such dryers draw airflow from the external environment, heat it using a heat source, and feed it through a plastic resin-filled hopper. The humidity from the plastic resin is picked up by the hot air and carried out of the bin. Hot air dryers are typically used for non-hygroscopic materials that accumulate humidity. Unfortunately, the surrounding stand-alone cannot remove all moisture from resins. Once you reach this stage, consider alternate drying options, such as cabinet dryers.

What Is the Function of Drying?

Materials have occasionally been exposed to damp screening or had fluid added to them to facilitate processing. The following stage goes through drying or dewatering to return the material to its original condition or develop a particular form for the finished product. Furthermore, if a residual waste must be burnt, drying might assist in preparing the item for suitable disposal. Drying is frequently the last stage in manufacturing before selling, packing, or storing a commodity. Adjusting moisture in solid materials is essential in chemical treatment because it reduces shipping and storage costs by reducing excessive liquid volume in a substance.

What Is the Process of Cabinet Drying?

Although there are numerous varieties of cabinet dryers, they all function in the same way. Cabinet dryers differ from typical plastic dryers because they use hot, dry airflow to remove moisture from plastic resin instead of ambient air. Air flows in a sealed process in cabinet drying systems, preventing air from departing the top of the bucket and entering the ambient air.

Dryer cabinet products are dehydrated to move onto stainless steel trays. Process air will flow to the hot wire throughout the operation and can be warmed to the necessary temperature.

What Are the Benefits of a Cabinet Dryer?

Compared with other forms of drying equipment, drying cabinets have several advantages, including higher efficiency, lower cost, and cutting-edge technology.

More Efficiency:

Cabinet drying boosts efficiency in your facilities while making your organization more energy efficient. Because these drying systems provide constant, closed-loop drying, the dehumidifier can absorb water more consistently, allowing the resin to move quickly from process to process. Most of these dryers include several critical components that make them a more energy-efficient option over time. Indeed, certain technologies featured in cabinet dryers are said to reduce energy consumption by 25 -30 %.


Cabinet dryers are more cost-helpful in the long term. You will identify this right after the first usage. These dryers assist in reducing other expenditures and enhancing your facility’s overall effectiveness, which can help you generate revenue and reduce operating costs. This drying technology, for example. The tightly closed chamber or system requires little maintenance and reduces contamination.

Greater productivity with an enclosed system:

Dryer cabinets are used to eliminate moisture from non-hygroscopic materials effectively and to preheat them before processing. When the product is placed in a cold area, this preheating is especially effective when processing in many humid and hot environments. They are typically made of a well-insulated feeder with a connected blower and heater. Wet air is dissipated into the atmosphere when hot air is blasted through the material particles. These dryers are made up of an enclosed system that contains materials that should be dried out. They lower the relative humidity, allowing moisture to evaporate more quickly. They are frequently used to reduce the moisture level of delicate materials.

Why should you choose TOPSTAR for your dryer cabinet?

A dryer cabinet is used to dry polymer or plastic raw materials, mainly when dealing with small amounts of varied materials or polymers for testing. After tempering, they can improve toughness, reduce tension, and improve the quality of plastic goods.
