The normal operation of spray dryer equipment should be safe, efficient and economical. Safe production can be achieved by correctly operating and protecting equipment. Even well-planned equipment can cause trouble if not operated properly, with untrained operators or incorrect operating instructions. According to statistics, more than 90% of industrial accidents are caused by human negligence. Therefore, it is necessary to strengthen the safety management of the spray dryer operation process.

Security management is a complex system engineering. It is an integral part of business management. This is an activity in arranging, planning, controlling, coordinating, and decision-making planning to ensure production safety. Its basic task is to discover, disperse and eliminate various risks in production, avoid accidents and losses, and ensure the life safety of operators.
The safety management of the spray dryer process mainly includes the safe operating procedures of the spray dryer system, equipment protection and operator training.

1. Safe operation of spray dryer system
In order to ensure the normal operation and safe production of spray dryer equipment, all spray dryer equipment should be equipped with clear operating instructions to organically connect equipment suppliers and users.
During equipment start-up and shutdown, the process is in an unbalanced state, which is considered a special risk period, and the process is likely to lose control. At this time, it is very important to measure and control the temperature and flow rate of the drying medium and materials. For spray dryer processes containing organic solvent liquids, the vapor concentration needs to be detected. In addition, during the operation of the equipment, safety inspections need to be carried out regularly, especially when there are changes in the equipment, materials or operating conditions.

2. Equipment protection and operator training
Operator training is necessary for the safe, efficient and economical operation of equipment. Operators should study the operating instructions to understand not only the normal operating procedures of the equipment, but also the possible risks during operation. The material risks of the spray dryer process should be fully assessed and some emergency safety measures should be taken in an emergency.

3. Dealing with fires and explosions caused by spray dryer systems
Regarding the spray dryer system, when a combustion or explosion occurs, the following measures should be taken as soon as possible:
1) Enclosed fan and heater
2) Close the feed valve and add a large amount of water to the atomizer as soon as possible
3) Pneumatic fire extinguishing equipment
4) Closed product discharge valve
5) Please do not enter the drying room
