Abstract

An apparatus for continuously sterilizes and fills food and medicines containing solids. In this apparatus, a filler nozzle is disposed downstream of a back-pressure tank, and a control valve is interposed between the back-pressure tank and the filler nozzle for controlling the flow rate of the products which are delivered from the sterilizer to the back-pressure tank. The control valve avoids a remarkable pressure loss which might otherwise be invited in the series passages of the apparatus. The outflow of air from the back pressure tank to the filler nozzle is minimized so that the back pressure can be applied to the sterilizer as stably as possible. At the same time, the sterilized products are continuously fed to the filler nozzle so that they can be packed simultaneously with their upstream sterilization.
