A plant is described which includes a continuous heat processing autoclave (1) for cooking and sterilizing food measured into tray-like containers (9). The open containers (9), loaded on to trays (12), are advanced through the autoclave (1) by a conveyor (40) operated stepwise. A cooling chamber (6) communicates at one end with the autoclave (1) through a pre-cooling and air-lock tunnel (7) and at the other with a sterile environment in which a sterile closure unit seals the containers (9) of cooked food.
