Nitrogen circulation spray dryer

The nitrogen circulation spray dryer is a spray drying machine for organic solvents, toxic or harmful materials. When the organic solvent concentration in the materials is too high, flammable and explosive, or the materials are suitable for oxidation, the machine uses nitrogen instead of the air in the drying and atomizing system. After passing through the filtering device and the multistage 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

Nitrogen sealed circulation greatly saves gas usage, ensures experimental safety, and prevents sample oxidation

Oxygen measurement system, automatically controls the start and stop of feed according to the high or low oxygen concentration

Sensitivity measurement system and automatic pressure relief

Efficient filtration system reduces material loss after drying

Multi stage pinhole solvent condensation system improves solvent recovery rate

Multiple temperature detection systems enable the drying effect of some thermosensitive materials to meet experimental requirements

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

The jacket type heating system reduces heat loss in the pipeline, has high temperature control accuracy, and ensures the safety of the machine at high temperatures

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

7-inch large LCD touch screen, temperature curve memory function, real-time monitoring, the whole machine is made of stainless steel material

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