An apparatus for continuously aseptically processing a food product comprising delicate food chunks of fruit, vegetables or the like immersed in a liquid. The apparatus comprises a heating enclosure into which the food product and a nonsterile gas are introduced into the food product heated to a sterilization temperature, and a holding enclosure which may be integral with or separate from the heating enclosure for holding the food product and a sterile gas introduced therein at the steriIization temperature for a predetermined time. The apparatus further preferably comprises a cooling enclosure for cooling the food product. In a preferred embodiment, a first separator is interposed between the heating and holding enclosures for separating a nonsterile gas from the food product. The food product and an added sterile gas are fed into a rotatable helical feed pump in the holding enclosure. A second separator receives the aseptic food product from the rotatable helical feed pump in the cooling enclosure for separating the aseptic gas and a portion of the liquid from the food product to produce aseptic food chunks which are then fed along with a predetermined quantity of the aseptic liquid to any suitable container filling machine.

A method and apparatus are disclosed for continuously and gently aseptically processing a food product comprising delicate food chunks of fruit, vegetables or the like immersed in a liquid. The apparatus comprises a heating enclosure into which the food product and a nonsterile gas are introduced and the food product heated to a sterilization temperature, and a holding enclosure which may be integral with or separate from the heating enclosure for holding the food product and a sterile gas introduced therein at the sterilization temperature for a predetermined time. The apparatus further preferably comprises a cooling enclosure for cooling the food product. Although the heating, holding and cooling enclosures are preferably separate enclosures provided with rotatable helical feed pumps in product communication with one another for feeding the food product and a gas through the enclosures in succession, the heating, holding and cooling functions may be achieved in a single enclosure through which the food product and gas are fed by a single helical pump. In a preferred embodiment, a first separator is interposed between the heating and holding enclosures for separating a nonsterile gas from the food product. The food product and an added sterile gas are fed into the rotatable helical feed pump in the holding enclosure.

55222

A geothermal steam condenser for reducing residual ammonia gas from a geothermal steam. The present condenser includes a column attached to the condenser for forming a curtain of temperature conditioned condensate, such that residual ammonia gas is passed through the conditioned water curtain to be furthered absorbed prior to exiting the geothermal steam condenser.

F01K 1300

60646

A method and apparatus for providing a required deaerating temperature differential between incoming water and sparge steam in a steam generation system having a vacuum deaerator. The present invention selectively combines raising the energy of the sparge steam with flash cooling of the incoming water to provide the required deaerating temperature differential. The energizing of the sparge steam is accomplished by a thermocompression device. The thermocompression device may also be used to reduce the pressure in a portion of the vacuum deaerator to cause the flash cooling of the incoming water.

95217

A method for reducing residual ammonia gas from a steam in a steam condenser. The method includes forming a condensate and a residual gas in a first stage, then forming a condensate curtain in the second stage and passing the residual gas through the condensate curtain prior to exiting the steam condenser. The method may be employed to remove ammonia and carbon dioxide gas from a geothermal steam.
