The rinsing turrets feature a semi-automatic electrical system (where provided) that adjusts the height of the grippers as the bottles pass by. The bottles coming from the conveyor belt are positioned in correspondence with the grippers that firmly seize the bottles around the neck (neck finish). Heavy bottles are lifted from the base with the help of a support.
During the rotation of the carousel, the grippers are overturned by means of a tubular guide (twist), and guided to the nozzle washing level. Every machine is made of AISI 304 stainless steel (AISI 316 upon request).
The plastic parts are made of certified food materials. An intercepting solenoid valve, for shutting off the rinsing fluid, automatically stops the flow every time the machine comes to a halt, and reactivates it when it is restarted. In addition to the traditional fixed nozzle, also a mobile nozzle system (optional) is available to improve the washing of the bottles because the nozzle goes inside the bottles.
A second rinsing or blowing cycle is also available, the so-called double treatment. After rinsing, the “dripping” phase takes place which ends when the gripper starts to once again rotate downwards by placing the bottles in the star which will bring them back onto the conveyor belt, towards the filling turret.
The machine’s injection system is built in such a way as to prevent the injection phase on the grippers which, for whatever reason, have not lifted up a bottle. This device avoids any upward splashing which could wet get both the machine and the surrounding environment.
The inspection machine’s functions are quite similar. The bottles, already filled and capped, are turned upside down using the same mechanism as the rinsing machine. This machinery, which does not have a valve for washing, serves to establish whether there are any foreign objects inside the bottle. Once the bottles are turned upside down they pass in front of a panel with bright lamps. Should an anomaly be detected, the bottle is discarded and eliminated from the production cycle.
