Abstract
An apparatus for sterilising material comprising a first pressure vessel, in which the pressure vessel has a vessel infeed and a vessel outlet. The vessel infeed and vessel outlet are adapted to form respective seals with the pressure vessel such that a desired pressure can be maintained in the pressure vessel, and wherein pressure vessel is depressurised such that the material deposited in the pressure vessel is sterilised and at least a portion of the inner surfaces of the pressure vessel are sterilised, such that the material deposited into the pressure vessel can be stored therein for a predetermined period.
Claims18
An apparatus for sterilising material, the apparatus comprising;
- a pressure vessel;
- the pressure vessel comprising a vessel infeed and a vessel outlet;
- the vessel infeed and vessel outlet are adapted to form respective seals with the pressure vessel such that a desired pressure can be maintained in the pressure vessel;
- and
- wherein the pressure vessel is depressurised such that the material deposited in the pressure vessel is sterilised and at least a portion of the inner surfaces of the pressure vessel are sterilised, such that the material deposited into the pressure vessel can be stored therein for a predetermined period of time.
A method of sterilising material in a multi-pressure vessel apparatus, the method comprising the steps of;
- depositing a material in a first pressure vessel;
- sealing the first pressure vessel and creating a depressurised atmosphere in the first pressure vessel;
- maintaining the depressurised atmosphere in the pressure vessel for a first predetermined holding time;
- depositing a material into a second pressure vessel;
- sealing the second pressure vessel and opening a fluid conduit between the first pressure vessel and the second pressure vessel such that the depressurised atmosphere from the first pressure vessel is used to partially depressurise the atmosphere of the second pressure vessel;
- closing the fluid conduit between the first pressure vessel and the second pressure vessel;
- and
- creating the depressurised atmosphere in the second vessel for a second predetermined holding time.
