Gaining a Competitive Edge in Stearate Drying

Gaining a Competitive Edge in Stearate Drying

Stearates—widely used additives such as calcium stearate, zinc stearate, and sodium stearate—are essential in polymer applications, serving as acid scavengers in polyolefins, lubricants, and stabilizers that enhance the longevity of thermoset products. With strong market demand, efficient and reliable drying of these fine powders has become a critical production challenge.

After extensive technical discussions, Changzhou Yidu Drying Equipment Co., Ltd. recommended its proprietary flash dryer for the final drying stage of stearate production. Over the past two years, our client has achieved remarkable results: high drying efficiency, minimal labor requirements, and significantly reduced operating costs.

The main challenge in drying stearates lies in their extremely fine particle size (low mesh count), which makes conventional baghouse dust collectors ineffective at capturing residual powder. To address this, Yidu engineered an enhanced dust collection system—optimizing material recovery without compromising throughput.

Equipped with our customized flash dryer, the production line now operates at full capacity under high-output demands, delivering consistent product quality and maximum yield.

At Yidu, our mission is simple: to design the right drying solution for every unique application. Through continuous collaboration, problem-solving, and innovation, we empower industries to dry smarter—and succeed faster.
