专利汇可以提供Apparatus for the sterilization of food products专利检索，专利查询，专利分析的服务。并且A method for sterilizing a food product contained in loosely sealed receptacles comprising placing the receptacles in an autoclave, drawing a vacuum, introducing steam to effect sterilization, reducing the pressure by drawing off or condensing the steam so as to evaporate some of the water contained in the receptacles and to thereby cause cooling of the receptacles and the food product, introducing a sterile inert gas to balance atmospheric pressure and sealing the receptacles before bringing them into contact with outside air. An apparatus for carrying out the method includes two concentric cylindrical shells defining between them an annular space. A spiral rail is secured to the inner surface of the outer cylinder and guides are secured to the outer surface of the inner cylinder so that rotation of the latter about its axis causes the receptacles to move along the rail. Appropriate valved inlets and outlets are associated with the annular space.，下面是Apparatus for the sterilization of food products专利的具体信息内容。

权利要求

1. Apparatus for effecting sterilization of unsealed receptacles comprising: an autoclave formed of inner rotatable and fixed outer concentric vertical cylinders defining between them an annular space, said autoclave having an inlet passage for receptacles near the upper end of said space and an outlet passage for receptacles near the other end of said space; means Including a driven shaft connected to said inner cylinder to rotate the same for distributing receptacles in said annular space and for moving receptacles through said space from said inlet to said outlet; valve means for closing said inlet and outlet; means including a conduit connecting with said space for drawing a vacuum in said space; means for introducing steam into said space and into the unsealed receptacles therein including a conduit connecting with said space for introducing steam into said space and receptacle-sealing means for sealing the receptacles after treatment with steam, said means including a sterilized chamber and passageway connecting the chamber with the autoclave into which the unsealed sterilized food-filled receptacles are moved.

2. Apparatus as in claim 1 wherein said outer cylinder is fixed, wherein the inner cylinder is rotatable about its axis and wherein said distributing and moving means includes shaft means for rotating said inner cylinder, a spiral rail extending from said inlet to said outlet and carried on the inner surface of the outer cylinder and guide means carried on the outer surface of said inner cylinder for urging receptacles along said rail upon rotation of said inner cylinder.

3. Apparatus as in claim 1 including a condenser and valve means for placing said condenser in communication with said annular space.

4. Apparatus as in claim 1 wherein the receptacle-sealing means includes a hollow, sterile enclosure and conveying means including a sterile conduit for conveying receptacles from said outlet into said enclosure.
