How to do the drying effect of spray dryer?

[Pharmaceutical Network Technical Article] Spray drying is a method of applying systematic technology to material drying, which can quickly dry solutions, emulsions and suspensions into powder or granular products, eliminating the need for evaporation, pulverization and other processes
.

Through mechanical action, spray drying will disperse the material to be dried into very fine mist-like particles, (increase the area of ​​water evaporation, speed up the drying process) and contact with hot air, so as to remove most of the water and make the solid in the material The substance dries to a powder
.

In recent years, spray dryers have been favored by the market due to their advantages of fast drying, good drying effect and low energy consumption.
Many enterprises will choose spray dryers for production and processing
.

In the pharmaceutical industry, pharmaceutical companies often use spray dryers, such as extending the shelf life of some valuable but difficult-to-preserve pharmaceutical intermediates, facilitating packaging, storage and transportation, and simplifying the processing technology.
The purity and quality of the intermediate product
.

However, according to many users, in the process of using the spray dryer, sometimes the equipment cannot be dried, or the drying effect is not good.
How to solve it at this time? There are factory technicians to help! In view of the situation that the spray dryer is not dry or does not heat up, it is recommended that the user can check the equipment first to check the seriousness of the problem.
If the problem can be solved by himself, he can solve it in time
.

"For example, heating element failure or thermal overload cut-off, etc.
, these can be solved by themselves, generally because the equipment does not have proper airflow, and the problem can be solved as long as the airflow condition is improved
.

" The technician said
.

 　　But what if the airflow isn't the problem? The person suggested that users can refer to the following practices, hoping to help everyone
.

 　　First, check whether the hose is blocked or bent.
Therefore, the blockage or bending of the hose will affect the airflow out of the spray dryer equipment.
Once the air circulation is not good, the dryer will not be able to heat up normally, which will affect the drying effect
.

 　　Second, if it is confirmed that the hose is not blocked or bent, then check whether the material is overloaded, because once the material is overloaded, it is easy to cause the machine to block, and the air cannot circulate freely
.

 　　Third, once the dryer is overheated, it will also affect the performance of the machine, and even damage the display
.

The person pointed out that a simple reset can be done if the thermal overload has been cut off
.

If it is found that the equipment has been seriously damaged, it is necessary to seek professional maintenance personnel to deal with the problem
.

 　　Although it is normal for a spray dryer to malfunction, after all, the equipment will wear out over a long period of time, and the performance will be affected after the wear to a certain extent, resulting in some problems such as poor drying effect, sticking to the wall, foaming powder, dust removal Ineffective, loud noise and other faults
.

 　　Users should pay attention to the maintenance and maintenance of the spray dryer in the process of using the equipment at ordinary times, so as to keep the machine in a state of long-term stable operation and better serve the production
.

 　　In addition, the quality of the spray dryer is also very important.
When choosing equipment, users should buy qualified and trustworthy products, with good product quality and guaranteed after-sales service, so as to avoid users' worries and put them into production more stably
