Abstract: For realizing short loading periods with a flexible transfer means (10) for a freeze drying plant comprising at least one freeze drying station (12) and at least one loading station (14,16), wherein said the transfer means (10) comprises at least one supporting frame (18) having a loading area (22) and an electrically operated laminar flow means (28) for producing a laminar air flow (30) in the loading area (22), said the transfer means (10) comprises a lifting carriage (16) which is adapted to be mechanically connected with said the supporting frame (18) for lifting and moving said the supporting frame (18) and comprises a drive motor and a steering means.

Abstract: An apparatus for the low energy vaporization of oxidizing agents, such as hydrogen peroxide and peracetic acid, relate to an apparatus comprising a storage tank containing a liquid oxidizing agent or solution, a vaporizer operatively connected to the storage tank for receiving the liquid through a flow control valve and vaporizing the liquid oxidizing agent or solution, a vessel having a vacuum applied thereto with the vessel being operatively connected to the vaporizer so that a vacuum is also applied thereto, and a pressure sensor in said vessel for detecting the partial vapor pressure of the oxidizing agent. A microprocessor is programmed to receive a signal from the vessel pressure sensor and to close the flow control valve upon the vessel reaching a predetermined pressure level so as to prevent condensation of the oxidizing agent and the vessel.

Abstract: A freeze-drying apparatus has a chamber (3) in which are located superposed charging plates (4) as well as loading and unloading equipment. The chamber has a loading aperture (2) equipped with closing doors (11, 12) through which the charging plates (4) are loaded. Equipment for loading the charging plates (4) with containers (5) is positioned in front of the loading aperture (2) and comprises a conveyor belt (6) which serves to supply the containers (5) and a transfer table (7) which is movable between an operating position and an idle position. The transfer table bridges a gap between conveyor belt (6) and the charging plate (4). A loading slider (8) provides push-wise transfer of a plurality of the containers (5) from the conveyor belt (6) via the transfer table (7) onto the charging plate (4).
