Generally, people who use the spray dryer find that the spray dryer is corroded. This is because some of the materials we dry are corrosive. After a long time of use, our spray dryer will be severely corroded, which will not only affect the spray drying. The entire service life of the machine may also denature the material, so it is necessary for us to protect the spray dryer from corrosion.
Many people know that spray dryers need to be anti-corrosion, but they don't really do it well, and it doesn't work, so today I will teach you a few tricks here.
1. We can adopt the spray dryer anticorrosion method of phosphating-passivation process. This method uses blood spotting and electrochemical reactions to make the surface of the rusty machine show its original color, and it can also be plated A layer of dense anti-rust film, good anti-rust effect on the machine. This anti-corrosion method will not rust even if the spray dryer is placed in a humid place for more than ten days.
2. There is also a method of electrostatic powder spraying. We all know that it is toxic to apply traditional paint in a spray dryer, because the paint itself contains organic solvents such as ester ketones and hydrocarbons. If paint is used for anticorrosion, it is easy to affect our materials, especially food materials are not feasible. In this case, professionals have introduced the method of electrostatic powder spraying, which has the characteristics of toughness and durability, and has excellent anti-corrosion effect.
