Abstract

Continuous-processing type sterilizer and cooker for providing packaged foods completely sterilized with a small heat-energy consumption and retaining the color, fragrance, taste, texture and quality similar to unprepared foods by taking the steps of immersing a product cage, wherein contains the packaged foods, in pressurized hot-water in a sterilization tank, moving the cage within the hot water by means of a drive means for a given period of time, transferring it through a transfer tank from the hot water to a pressurized cooling water in a cooling tank, and moving it within the cooling water by means of a drive means for a given period of time. Both the sterilization tank and the cooling tank are connected to the transfer tank at their one end, the sterilization tank having a preparatory chamber at its other end and the cooling tank having an off-loading chamber at its other end. The chamber is provided with an elevator, lowering or raising within the connecting portion between the chamber and the tank, and separating the chamber from the tank in a manner that the rim of the elevator is bound to the flange of the lower end of the chamber thereby forming an airtight system.
