How to clean the spray dryer correctly?

　　Cleaning spray dryer is an important part of routine maintenance. However, if it does not understand its cleaning methods, it will easily cause improper cleaning and damage the machine. So how should we wash it?

　　The spray dryer consists of various parts, such as nebulizer, exhaust system and so on. The cleaning of each part plays a very important role, because a part or part is closely related to the overall efficiency. So we should pay attention to the methods of cleaning and daily maintenance of various parts, especially the nozzle. In order to ensure the normal operation of the dryer when it is used next time, it is suggested that the nozzle should be cleaned after each use. In addition to cleaning, maintenance work should also be paid attention to at ordinary times.

　　There are three ways to clean the nozzle: chemical cleaning, dry cleaning and wet cleaning. You can choose different cleaning methods according to your own conditions and needs.

　　1. Chemical cleaning is the use of a variety of chemical reagents to help you clean, such as a variety of chemical detergents or acid-base solutions and so on.

　　2. Dry cleaning does not add any detergent, but simply use some tools to roughly clean the nozzle, such as using a brush to simply brush the surface of the nozzle, or using a vacuum cleaner to absorb the residual product particles and some dust on its surface.

　　3. Wet washing refers to washing the nozzle with hot water to achieve the dual purpose of disinfection and cleaning.

　　Among the three methods, the wet cleaning method is more thorough, and it also disinfects the nozzle at the same time. It should be noted that the hot water used here is generally between 60 ℃ and 80 ℃, because the hot water in this range has the best cleaning effect.

　　When cleaning the nozzle, remember not to wash the nozzle at will, and pay special attention to the protection of the nozzle at the same time. Regular cleaning and maintenance can ensure the normal working ability of the equipment and extend the service life of the equipment to a certain extent. But if you don't pay attention to protect the machine when cleaning the nozzle, especially when using chemical reagents for cleaning, if you don't pay attention, it will damage the machine. In the end, it will backfire. It's better not to clean.

　　Therefore, the daily cleaning and maintenance of spray dryer is very important to the machine. When cleaning, we must pay attention to standard operation and do well the protective measures of the equipment, which is of great significance for prolonging the life of the equipment and ensuring its next normal use.
