AS Engineers’ Paddle Dryer/Cooler is designed to transport a plethora of material types regardless of their chemical properties. You will rarely need to precondition the feed by mixing it with the recycled dry product to make it more conveyable. Hence, your overall operating, capital, and maintenance costs are drastically brought down.
The material is conveyed through our dryer/cooler by displacement. The agitators, at the feed end, assimilate the materials. In tandem with the action of the wedge-shaped paddles, hydraulic head pressure is applied. This pushes the material around and also between the paddles. There exists a certain high degree of localized agitation, and some amount of back mixing but the overall flow pattern can be described as a plug-flow movement down the processor with excellent mixing in the radial direction. There is equal residence time for all particles inside the Paddle Dryers which provides uniform product quality.
You can control the residence time by the height of the overflow weir or by the removal of material with a bottom discharge screw that is provided. For those applications where very high volumes need to be conveyed, or low residence times are required, one can pitch the paddles and can incline the processors so as to increase the overall conveyance rate.
Customized Design
We give special attention to details which results in a product that is enriched with vital key features. Our Paddle Dryer has a dust-proof sight glass and a special lid for taking samples.Â
Similarly, our Paddle Dryer comes in a variety of configurations to help you run your day-to-day processes smoothly. For instance, two separate heat zones can be constructed if it is needed. We also provide a vacuum model that allows the drying temperatures to remain low for heat-sensitive food products. A special version is also available for crystallizing and drying PET which ensures degradation-free processing and a tiny residence time.Â
All our Paddle Dryer units are on a slight incline which enables a good flow of the product particles by gravity.

Paddle Dryer Applications in the Chemical Industry
In the chemical industry, paddle dryers play a crucial role in various applications, ensuring efficient and effective drying processes. These versatile machines are widely used for drying different materials, including polymers (such as PET, SAP, and PA), gypsum, minerals, metal powders, and lithium. Let’s delve into each of these applications to understand their significance:
Polymers (PET, SAP, PA): Paddle dryers are indispensable in the polymer industry for drying materials like Polyethylene Terephthalate (PET), Super Absorbent Polymers (SAP), and Polyamide (PA). These polymers are often produced with residual moisture, which needs to be removed to meet specific product requirements. Paddle dryers excel in this task by providing uniform and controlled drying, ensuring the desired moisture content is achieved. The result is high-quality polymer products ready for various applications.
Gypsum: Gypsum, commonly used in construction and agriculture, often needs to be dried to a specific moisture level for optimal performance. Paddle dryers are ideal for this purpose. They evenly distribute heat and ensure consistent drying, preventing clumping and improving the flow properties of gypsum. This enhances the quality of gypsum products used in making plaster, cement, and soil amendments.
Minerals: Paddle dryers are employed in the mineral industry for drying various mineral concentrates and ores. The controlled drying process is essential to reduce moisture content and enhance the value of the minerals. These dryers maintain product integrity, preventing material degradation and ensuring that the minerals are ready for further processing or sale.
Metal Powders: Metal powders are used in a wide range of industries, from aerospace to automotive. Paddle dryers are crucial in the production of metal powders, as they help remove moisture and prevent oxidation, ensuring the powders’ quality and consistency. By controlling temperature and humidity, these dryers aid in achieving the desired characteristics of the metal powders.
Lithium: The demand for lithium, especially in battery production, has increased significantly in recent years. Paddle dryers are used to dry lithium compounds efficiently and uniformly. This is critical in maintaining the purity and performance of lithium-based products, such as lithium-ion batteries. Paddle dryers ensure that the lithium materials are ready for further processing and integration into batteries.
In summary, paddle dryers are indispensable tools in the chemical industry, offering precise and consistent drying solutions for a wide range of materials, including polymers, gypsum, minerals, metal powders, and lithium. Their ability to control moisture levels, prevent product degradation, and maintain material quality makes them an essential asset in various chemical processes. For businesses in the chemical industry, investing in paddle dryers is not just a choice; it’s a necessity to ensure the highest quality of end products specific needs.
