How to clean the centrifugal spray nozzle of centrifugal spray dryer?
When we use the centrifugal spray dryer equipment, in order to ensure the next normal use, it needs to be cleaned and maintained by the centrifugal nozzle. So, when cleaning the centrifugal spray dryer centrifugal nozzle, do you know which methods can be used? Let's take a look at the specific content below.
In fact, we can choose different methods according to the specific situation, so as to complete the cleaning of the centrifugal spray dryer centrifugal nozzle. As far as the current situation is concerned, there are three main cleaning methods that can be used, namely dry cleaning, wet washing and chemical washing. The chemical washing method can also be divided into alkaline liquid, acid liquid and various detergent cleaning. The so-called dry cleaning mainly refers to cleaning with a brush, a broom, a vacuum cleaner, and the like.
So what is wet washing? The so-called wet washing refers to the cleaning of the centrifugal spray nozzle of a centrifugal spray dryer using hot water with a temperature in the range of 60 to 80 degrees Celsius. The alkali washing means that sodium hydroxide (NaOH) is formulated into a solution of 0.5-1% concentration, and then heated to 60 to 80 degrees Celsius, and then washed, and then rinsed with water after cleaning.
In addition to this, the so-called pickling mainly means that (HNO3) is formulated into a solution at a concentration of 1-2% and heated. At this time, it should be noted that the heating temperature should not exceed 65 degrees Celsius. After that, the centrifugal spray head of the centrifugal spray dryer is washed, and then rinsed with water. It should be noted that after the wet and chemical washing is completed, the various components of the equipment need to be installed and subjected to high temperature sterilization. The disinfection time is approximately 15-30 minutes.
In the process of cleaning, care should be taken to protect the centrifugal spray nozzle of the centrifugal spray dryer. It is important to note that chlorine and its compounds should not be used for washing to avoid oxidation. In short, when cleaning the centrifugal spray dryer centrifugal nozzle, we not only need to pay attention to clean up, but also should be prevented from being adversely affected.
