A closed-loop spray dryer, also known as an organic solvent spray dryer, is a common piece of lab equipment that is mainly used to dry organic solvents or solutions containing organic solvents. It adopts a closed circulation system, which can effectively prevent the volatilization and leakage of organic solvents, and can also avoid pollution to the environment.
The working principle of a closed-loop spray dryer is to atomize the organic solvent or solution that needs to be dried into fine droplets through a nozzle and then spray it into the drying chamber. In the drying chamber, the droplets are rapidly heat exchanged with the hot air, allowing the solvent to evaporate and dry quickly. After drying, the solid particles fall to the bottom of the drying chamber, while the exhaust gases are discharged after dust removal treatment.
Since the closed-loop spray dryer adopts a closed circulation system, it can effectively prevent the volatilization and leakage of organic solvents. At the same time, because the organic solvent is dried in a closed system, it can avoid pollution to the environment and meet the requirements of environmental protection.
Read Paving the way for the future Closed-loop spray dryers offer a variety of benefits. First of all, it can be applied to the drying of a variety of organic solvents, and has a wide range of applications. Secondly, due to the closed circulation system, the amount of organic solvent used can be effectively saved. In addition, the closed-loop spray dryer also has the advantages of easy operation, high efficiency, safety and reliability. When using a closed-loop spray dryer, you need to pay attention to the following points. First of all, it is necessary to choose a suitable organic solvent or solution for drying to avoid damage to the equipment. Secondly, it is necessary to ensure that the sealing performance of the equipment is good and prevent the leakage of organic solvents. In addition, regular maintenance of the equipment is also required to ensure its normal operation and service life. In conclusion, the closed-loop spray dryer is an efficient, environmentally friendly and safe laboratory equipment, which is suitable for the drying of a variety of organic solvents. When using, it is necessary to pay attention to the sealing performance and scope of application of the equipment, and carry out regular maintenance.
