Injector: Inject raw material to mixing head directly. The running speed and circulation of cleaning solution, air,mixing head are controlled by each single system. It can reach the best cleaning effection . In order to save the consumption, it can also set the pre-cleaning program for each component.

The manual cleaning type for the emergency situation of emergency power off is also available for this machine.

Note : The function of automatic cleaning could also be designed.

Option of cleaning solution : none inflammable and explosive Solution, like : DBE/MC.
