The invention relates to the batch treatment of goods with gas, steam or vapor, for example sterilization and drying. The distribution of the medium surrounding the load (8) during all stages of such a process is important. According to the invention, movement of fluids within a batch treatment apparatus is achieved using a fluid ejector device (9), An apparatus for the gas, steam or vapor treatment of objects is provided, said apparatus having inside a closable chamber (1) at least one ejector device (9) of the type having a straight flow path for the secondary stream. Any particular fluid or mixture of different fluids entering the chamber during a treatment process may be introduced via an ejector device (9) in order to distribute the fluid around the load (8), or remove material deposited on the load (8). The invention eliminates the need for shaft seal arrangements involved with fans.
A device for treating batches of objects with gas, steam or vapor, the device comprising a closable chamber for containing said objects and at least one ejector device for generating a secondary gas stream within the chamber by means of a primary stream, characterised in the ejector device or devices being located within said chamber and the flow path of the secondary stream through the ejector device or devices being an essentially straight line.
