The Semi Automatic Bottle Cleaning machine works on compressed air and suction blower arrangement. The bottles are placed in inverted position manually on the nozzle. As soon as the bottle is placed, the solenoid valve actuates and filtered compressed air is sprayed inside the bottle and the suction blower sucks the foreign particle if any. After cleaning, the bottles are transferred manually to the filling machine.
It gives an output of 20 to 40 bottles per minute depending on operator skill.
