CIRCUIT FOR EXHAUSTING AIR FROM A PARISON SYSTEM FOR SUPPLYING AND EXHAUSTING AIR FROM A PARISON AND ASEPTIC MOULDING PROCESS USING SAID CIRCUIT AND SAID SYSTEM

摘要

Process of moulding a container in a contamination controlled environment (102) starting from a parison (20) made of plastic material comprising the steps of: injecting air into the parison (20) at the maximum pressure of 16 bar and subsequently at the maximum pressure of 40 bar in such a way as to obtain the container; discharging the air from the parison or from the container (20) externally of the contamination controlled environment (102) until the air pressure inside the container (20) reaches a predetermined value comprised between 0.5 bar and 3 bar; completing the discharge of the air from the container (20) towards the contamination controlled environment (102).
