Cleaning Method Of Centrifugal Spray Dryer
After using the centrifugal spray dryer equipment, in order to ensure the next normal use, it is necessary to clean and maintain the centrifugal spray. So, when cleaning centrifugal spray dryer centrifugal nozzle, do you know what methods can be used?Let’s take a look at the details.
In fact, we can choose different methods according to the specific situation, so as to complete the cleaning work of the centrifugal spray dryer. As far as the present situation is concerned, there are three main cleaning methods:
1.Dry cleaning. Dry cleaning mainly refers to the use of brushes, brooms, vacuum cleaners, etc.
2.Wet washing: wash with hot water at 60-80℃
So, what is wet washing? The wet washing actually refers to the use of hot water in the temperature range of 60 to 80 degrees Celsius centrifugal spray dryer nozzle cleaning. Alkaline washing, on the other hand, involves mixing sodium hydroxide (NaOH) into a solution of 0.5-1% concentration, heating it to 60 to 80 degrees Celsius, washing it, and then rinsing it with clean water.
In addition, the so-called pickling mainly refers to the nitric acid (HNO3) at the concentration of 1-2% after the preparation of a solution and heating it. At this time, the heating temperature should not exceed 65 degrees Celsius. Then wash the centrifugal spray head of the centrifugal spray dryer, and finally rinse it with clean water. It is important to note that after wet and chemical washing, all parts of the equipment should be installed and thermophilic. The disinfection time is about 15-30 minutes.
3.Chemical washing. The chemical washing method can also be divided into lye, acid, and a variety of detergent cleaning.
In the process of cleaning, attention should be paid to protect the centrifugal spray nozzle of the centrifugal spray dryer. In particular, chlorine and its compounds should not be used for washing to avoid oxidation. In short, when cleaning the centrifugal spray head of the centrifugal spray dryer, we not only need to pay attention to clean it, but also to prevent it from being adversely affected.
