Product Introduction:
BA-DGZJ5L nitrogen closed-loop circulating spray dryer is a spray drying model for organic solvents, toxic or harmful materials, the concentration of organic solvents contained in the materials is too high, flammable and explosive or the materials are suitable for oxidation, the machine uses nitrogen instead of the air of the drying atomization system, and the nitrogen is circulated and closed after the filtration device and multi-stage condensing device, so as to achieve the safety of the experimental process, and also make the sample not oxidized, and complete the drying and collection process.
Product features:1Nitrogen is tightly circulated, which greatly saves the amount of gas used, realizes experimental safety, and prevents sample oxidation.
2.The precision oxygen measurement system automatically controls the start and stop of the feed according to the oxygen concentration to achieve the safety of the experiment.
3.Sensitive pressure measurement system and automatic pressure relief to achieve the safety of space pressure.
4.The efficient filtration system greatly reduces the loss of materials after drying.
5.Multi-stage pinhole solvent condensation system greatly improves the highest rate of solvent.
6.Multiple temperature detection systems to achieve the drying effect of some heat-sensitive materials.
7.The inverter fan can arbitrarily control the size of the inlet and outlet air volume, which greatly reduces the loss of fine materials.
8.The jacketed heating system reduces the heat loss of the pipeline, has high temperature control accuracy, and also realizes the safety of the machine at high temperature.
9.The vortex separator of the drying tower can be separated for cleaning, which solves the temperature of difficult cleaning.
10.7-inch large LCD touch screen, temperature curve memory function, real-time monitoring, the whole machine is made of stainless steel.
11.Self-produced nitrogen generator can be selected to reduce the frequency of use of nitrogen cylinders.
