Research on Displacement Drying Technology

Henan Bailing Machinery Co., LTD has developed the new energy efficient drying technology using the displacement drying technology, the product quality is praised by the majority of users, Bailing dryer is trusted!

The advantages of replacement drying include:

1. Reduce energy consumption compared with the hot air drying;

2. A high drying rate, reducing the drying time;

3. Low investment and operating costs;

4. Dry the materials of higher moisture content without reducing the drying efficiency.

In addition, the drying technology will not leave any spot, and moisture traces is not leaved at surface, it is especially important in the dry film, plastic, polished metal products, ceramics and so on.

Bailing Machinery research on the drying technology: Displacement drying is a method of non-heat and dehydration, when the solvent of miscibled with water and the density is higher than the water used to "exchange" wet material and invade drying solvent, replacement in the joint effect by buoyancy and surface forces occurred. Then the mixture of two liquids separated through gravity, centrifugal or evaporation, recycling into the drying system. The process depends on the ability of displacement liquid separate water droplets from solid surface. Because the water - solvent, and water - surface tension between solid interfaces are the key factors to release water, this process can be strengthened by adding surfactants.
