Advantages: the equipment does not need to stop, does not affect the normal production and use. Disadvantages: cleaning effect relative to off-line cleaning is not very good. The cleaning time is long, and the corrosion of the equipment is great.

Advantages: reduce the amount of medicine, good cleaning effect. Disadvantages: need the corresponding equipment, such as cleaning the car or cleaning water tank, high pressure pump, various specifications of the connection valve, welding equipment, etc
