Product Introduction

BA-PWGZ3000 nitrogen closed cycle spray dryer is a spray dryer for organic solvents and 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 to replace the air of the drying atomization system. Nitrogen is used in a closed cycle after passing through the filter device and multi-stage condensation device, so as to determine the safety in the experiment process, and also to prevent the samples from being oxidized, and complete the drying and collection process

Product features:
1. Nitrogen sealed circulation, saving gas usage, ensuring experimental safety, and preventing sample oxidation
2. A high-precision oxygen measurement system that automatically controls the start and stop of the feed based on the concentration of oxygen, improving the safety of the experiment
3. Sensitivity measurement system and automatic pressure relief to improve the safety of space pressure
4. Efficient filtration system reduces material loss after drying
5. Multi stage pinhole solvent condensation system to improve solvent recovery rate
6. Multiple temperature detection systems to ensure the drying effect of some thermosensitive materials
7. Variable frequency fan allows for arbitrary control of the inlet and outlet air volume, reducing the loss of small materials
8. The jacket type heating system reduces heat loss in the pipeline, has high temperature control accuracy, and also improves the safety of the machine at high temperatures
9. The vortex separators in the drying tower are detachable for cleaning, solving the problem of difficult temperature cleaning
10.7-inch large LCD touch screen, temperature curve memory function, real-time monitoring, the whole machine is made of stainless steel material
11. Optional self-produced nitrogen generator to reduce the frequency of nitrogen cylinder usage
