Closed cycle spray drying device

In response to national environmental protection policies and in chemical, pharmaceutical and biological engineering, products are often involved in poor drying and temperature resistance, and the moisture content of finished products is strictly required. In this case, ordinary dryers often have a long drying time, and the finished product cannot meet the requirements. The use of closed-circuit drying device can solve these problems very well.

1. Working principle

In the closed-circuit drying process, the drying medium is nitrogen or air with low moisture content, and the process of carrying moisture and dehumidification is repeated in the closed-circuit drying system until the product is dried. Usually, the wet ingredients in wet materials contain solvents. , using nitrogen as the drying medium.

During the drying process, the volatilized wet components are condensed and collected by the condensation system, and the non-condensable gas has a larger moisture-carrying capacity after continuing to heat up, so that it can better continue to participate in drying.

2. Features

1. The drying medium does not need high temperature, but the moisture content of the finished product can be very low;

2. The product can be dried without oxygen, without oxidation, denaturation and degradation, and without the danger of burning and explosion;

3. The solvent is recovered and the cost is saved;

4. No waste gas and dust are discharged into the atmosphere;

5. The product can be cooled in the original system, and the finished product has no moisture absorption phenomenon;
