Customer Reviews
 I would like to thank you for all your efforts to choose the correct atomizer for our spray dryer,High speed drying. The surface area of Raw Material liquid increased a lot after atomization through nebulizer, 95%-98% of moisture will be evaporated in high temperature airflow in a flash, only needs seconds time.

—— Fatih BÜYÜKEGEN

I really don't know how to thank you, you are my angel, Thank you very much. Super Fine Pulverizing this one is faster than other same power machine and is easy to operate and repaired.

Reference factors for choosing a high-efficiency coating machine


1. The location of the spray gun
That is, the position of the atomizing spray gun in the coating drum, there are generally two modes, the spray gun is facing the lower position inside the drum or the spray gun is facing the inner wall of the drum.


a certain location. - Generally speaking, this mode is very important to the coating quality, and in China, the mode of the spray gun facing the lower part of the drum body is the main mode.
 

2. Spray gun operation
That is, the spray gun is easy to operate and easy to master, no tools are required for disassembly, and the process requirements are flexibly controlled.

 

The volume and angle of the fan are adjustable. The atomization is uniform and the spray surface is large.

3. Spray speed
That is, the amount of atomization, which is the total amount of the sprayed coating liquid (suspension) per unit time.

 

4. Atomization pressure excitation
The second concept is the pressure of the mist generated by the atomizing gas and the suspension at the spray gun and the pressure of the atomizing gas itself.

 

5. Air inlet temperature
That is, the temperature of the hot air in the inlet drum used to dry the coated tablets.

 

6. Total air intake
That is, the air volume used for drying and penetrating the tablet bed in the inlet drum is usually adjusted to be slightly larger than the inlet air volume, so as to cause the coating to roll.

 

There is a slight negative pressure in the cylinder, so that the coating liquid can smoothly enter the tablet bed.
 

7. According to the internal force of the drum


The pressure difference between the coating drum and the chamber, and the insufficient excitation difference causes the coating liquid to not be inhaled into the tablet bed, but adheres to the surface of the tablet bed, at the entrance, and at the tablet bed.


On the inner wall of the drum or on the spray system; high excitation will bring excess coating liquid into the tablet bed.
 

8. The rotation speed of the coating drum
There is a theory that the rotation speed of the coating drum should be set to be constant based on experience, but how it is to be discussed.

 

9. Cleaning system
There are pressure spray guns inside and outside the coating pot, and cleaning nozzles are arranged at the air outlet and hot air outlet, which can automatically rotate in all directions without dead ends, making cleaning more convenient and easier.

 

Scope of Application

 

Coating machine is a high-efficiency, energy-saving coating for sugar coating, organic film coating, water-soluble film coating, and slow and controlled release coating of Chinese and Western medicines, tablets, pills, micropills, small pills, water pills, dripping pills, granule pills, etc. , Safe, clean, mechatronics equipment that meets GMP requirements.
