Indirect Batch Paddle Dryers allow an end-user to maintain a high degree of precision when it comes to drying factors such as batch time, temperature, and airflow. These dryers are often selected for applications where achieving the desired moisture content without material degradation is crucial.
Reduces Material Degradation Concerns
In contrast with direct heat drying technology, Indirect Batch Paddle Dryers reduce the risk of thermal decomposition or degradation. Sometimes, these dryers use an agitator to mix the material and displace it in contact with the vessel wall. This gentle mixing action provided by the rotating agitator helps prevent localized overheating and ensures the effective handling of sensitive materials such as chemical compounds.

Consistent Heat Transfer
Hot oil or steam jackets are typically used to indirectly heat the vessel of the Indirect Batch Paddle Dryer. This approach to indirect heating is advantageous because it allows for maximizing surface area contact between the heating jacket and the vessel’s wall, promoting uniform drying throughout the batch. As mentioned, heat transfer minimizes the likelihood of thermal gradients that can cause product quality issues.
Range Of Compatible Materials
From a material science standpoint, Indirect Batch Paddle Dryers are designed to handle various materials. These include fine powders, cohesive materials, and heat-sensitive compounds. These dryers are often designed to include corrosion-resistant materials such as 304 stainless steel, 316L stainless steel, or nickel-based alloys.
Paddle Dryers are uniquely positioned to provide versatile and efficient solutions to end-users. These systems are often designed to utilize vacuum technology, which is also advantageous for temperature-sensitive materials.
