When using a refrigerated spray dryer, you need to pay attention to the following issues:
Operational safety: During operation, special attention must be paid to safety. Especially in the process of closed operation, if organic solvents (such as ethanol, xylene, etc.) are used, the oxygen concentration must be controlled below 5%, otherwise the organic solvent may burn or**. At the same time, it is forbidden to open and close the refrigeration dryer frequently, so as not to burn out the compressor motor.
Equipment maintenance: After the equipment is shut down, please do not touch parts such as bag filters, cyclones, air ducts, atomizers, exhaust fans, and observation windows due to the high surface temperature. At the same time, the two filler ports of the atomizer must be lubricated each time before opening the spray dryer.
Parameter control: In the process of operation, it is necessary to control the relevant parameters. For example, the refrigerant pressure gauge should show the value within the specified range, if the refrigerant pressure value is zero, it means that the refrigerant has leaked, and it is necessary to contact the personnel for maintenance as soon as possible. At the same time, try to avoid the refrigeration dryer running for a long time when there is no load.
Experimental operation: During the experiment, it is necessary to pay attention to the properties and drying effect of the material, and adjust the operating conditions and parameters as needed. For example, the nature and yield of the product can be controlled by adjusting parameters such as inlet air temperature, feed volume, etc.
Cleanliness and hygiene: During use, it is necessary to keep the equipment clean and hygienic. Regularly clean and disinfect the equipment to avoid the impact of material residues on the performance of the equipment.
In short, when using refrigerated spray dryers, it is necessary to pay attention to safety, equipment maintenance, parameter control, experimental operation and cleaning and hygiene. Only proper use and maintenance of the equipment can guarantee its performance and longevity.
