Closed loop spray dryer

The SPRAY-500YA closed circuit circulating spray dryer is a spray dryer for organic solvents or harmful materials. When the concentration of organic solvents in the materials is too high, flammable and explosive, or the materials are suitable for oxidation, the machine uses nitrogen to replace the air in the drying and atomizing system. After passing through the filtering device and multi-stage condensing device, nitrogen is used in a closed cycle, so as to ensure the safety during the experiment, and also ensure that the samples are not oxidized, and complete the drying and collection process.

Product Features

1. Nitrogen sealed circulation greatly saves gas usage and prevents sample oxidation

2. The closed cycle spray dryer is equipped with an oxygen measuring system to automatically control the start and stop of the feeding according to the oxygen concentration

3. Pressure measurement system and automatic pressure relief

4. The filtration system greatly reduces the loss of materials after drying

5. Multi stage pinhole solvent condensation system to improve solvent recovery rate

6. Multiple temperature detection systems to protect the drying effect of some thermosensitive materials

7. Variable frequency fan, which can control the inlet and outlet air volume and reduce the loss of small materials

8. The jacket type heating system reduces heat loss in the pipeline and has good temperature control effect

9. The vortex separators in the drying tower are detachable for cleaning, solving the problem of difficult cleaning

10. The closed cycle spray dryer adopts a 7-inch large LCD touch screen, temperature curve memory function, real-time monitoring, and the whole machine is made of stainless steel

11. Optional self-produced nitrogen generator to reduce the frequency of nitrogen cylinder usage
