A vertical evaporator has an inner tube containing a heat exchanger for heating water and an outer tube which is coaxial with and surrounds the inner tube, forming a sealed system and leaving a peripheral space between the two tubes. The inner tube has bottom outlets through which steam and water droplets generated by heating water by the heat exchanger are ejected. A helical fin is attached to the outer surface of the inner tube for centrifugally separating steam and water droplets moving up inside the peripheral space as they are guided by the helical fin. The outer tube has a steam outlet at an elevated position for discharging pure steam separated from water droplets, as well as an indentation above the helical fin for collecting water droplets which are centrifugally separated from steam. A discharge pipe is provided, leading to the indentation for discharging water collected in the indentation.

Vertical evaporator

Apparatus for sterilizing packed foods includes a sterilizing chamber for storing packed foods therein, a jet pipe mounted onthe interior upper portion of the sterilizing chamber for jetting mixture of steam and compressed air, an ejector having an inlet port, a suction port and an outlet port and connected at the outlet port to the jet pipe for generating a suction force through a flow of mixture of steam and compressed air, a steam line connected to the inlet port of the ejector for supplying steam thereto, a circulation line connected at one end to the interior lower portion of the sterilizing chamber and at the other end to the suction part of the ejector, a drain line connected to the bottom of the sterilizing chamber for exhausting a part of the mixture of steam and compressed air, a heat exchanger interposed between the sterilizing chamber and the drain line, and a compressed air line connected to the inlet port of the ejector through the heat exchanger.
