Abstract:
1. Unit for sterilising and depyrogenating containers of the type comprising a conveying device suitable for receiving a plurality of said containers through at least an inlet and supplying said containers in a set direction to a corresponding outlet of the unit wherein said unit comprises a sterilising/depyrogenating arrangement defined by at least two sterilising modules, arranged consecutively in said direction and communicating through an intermediate passage, and affected by said conveying device; said sterilising modules being activatable independently of one another according to alternative operating modes for hot sterilising and/or cooling said containers, wherein each of said at least two sterilising modules comprises: a generating device for generating an air flow, suitable for generating and conveying said air flow along a path to said containers; a filtering element suitable for filtering said air flow up to a preset degree of purity; a heating element suitable for heating said air flow and intended for affecting said containers inside a sterilising chamber to take said containers to a preset sterilising and depyrogenating temperature, along a heating branch affected by said heating element; a refrigerating arrangement suitable for cooling said air flow along a cooling branch affected by said refrigerating arrangement; a flow commuting member, arranged along said heating branch and a further flow commuting member arranged along said cooling branch; said flow commuting member and said further flow commuting member being commutable between respective open and closed positions to connect or disconnect said heating branch or said cooling branch from said air flow path such that each of said at least two sterilising modules is selectively and alternatively operatable as a hot steriliser and in a cooling operating mode.
