Why is the reason of centrifugal spray dryer appear to stick to the spray drying chamber? How to solve the problem on Spray Drying Machine Powder sticking?

 

The centrifugal spray dryer is a device that uses a centrifugal atomizer to dry some liquid materials. Spray Dryer has the characteristics of fast drying speed, simplified production process, suitable for continuous control of production, and improved product purity. It is widely used in food, chemical, pharmaceutical, and pharmaceutical industries. Environmental protection and other industries.

 

 

The working principle of the centrifugal spray dryer is: the air passes through the filter and the heater, enters the air distributor on the top of the centrifugal spray dryer, and the hot air enters the spray drying machine chamber uniformly in a spiral shape. The material liquid is pumped from the material liquid tank through the filter to the centrifugal atomizer on the top of the spray drying machine chamber, so that the material liquid is sprayed into very small mist droplets. The material liquid contacts the hot air in parallel, and the water evaporates quickly. It is dried into finished product instantly, and the finished product is discharged from the bottom of the spray drying machine tower and cyclone separator, and the exhaust gas is discharged by the fan. It is understood that users can also select the heating method, dust collection and dust removal method according to the actual situation.

 

At present, the application of centrifugal spray dryers in the field of medicine has been very extensive. There are a wide variety of products on the market, which makes the drying efficiency of the pharmaceutical industry higher. In order to improve the uniformity, fluidity and solubility of the material products, some equipment manufacturers also Intensify research and development, continue to innovate the process, and create a high-speed centrifugal spray dryer with faster drying speed, higher product purity, and more convenient operation and control to meet the new needs and requirements of material drying of pharmaceutical companies.

 

It is worth mentioning that in the process of using centrifugal spray dryers, many users often find that the Atomization Nozzle of the equipment are malfunctioning. For example, during the production process of centrifugal spray dryers, the speed of the Atomization nozzles is too low, the evaporation rate is too low, and the centrifugal atomize nozzles are running. There are noises or vibrations from time to time, and even the equipment cannot work normally. Therefore, it is very important to understand the causes of spray nozzle failures and solve the problems.

 

 

So, how should we deal with it? The industry believes that there are two aspects for reference. First, if you find noise or vibration during the operation of the centrifugal nozzle in Spray Drying machine Chamber, it may be caused by improper cleaning and maintenance of the spray dryer nozzle, resulting in residual substances in the nozzle or bending and deformation of the spindle; the second may also be Caused by poor dynamic balance of the centrifugal disc.

 

"If the nozzle speed is too low and the spray drying evaporation rate is too low, it may be that the centrifugal nozzle components are malfunctioning. You need to stop using the nozzle first and check the internal components of the nozzle. The reason may be: the air volume of the entire system is reduced; the inlet temperature of the hot air is low; There is air leakage in the equipment, and cold air enters the drying room." The above-mentioned person said.

 

 

It is very important to clean and maintain the spray nozzle of the centrifugal spray dryer regularly, otherwise it may cause subsequent failures from time to time. To solve the problems caused by this kind of reasons, the method is to check whether there are residual substances in the spray disk, and if there is any, spray drying machine should be cleaned in time; if the spindle is found to be abnormal, it must be replaced. The dynamic balance of the centrifugal disk should be re-adjusted or replaced to solve the problem of nozzle failure.

 

In addition, it is suggested in the industry to check whether the rotation speed of the centrifuge is normal; check whether the position of the spray dryer centrifuge regulating valve is correct; check whether the air filter and air heater pipes are blocked; check whether the grid voltage is normal; check whether the electric heater is normal Work; check whether the connection of each component of the spray dryer is sealed, etc., and do a good job of inspection to further troubleshoot and solve the problem, to ensure the stability of the equipment next time.
