Abstract: Provided is an innovative method for sterilization or inactivation treatment of heat-resistant spore-forming bacteria that demonstrates a sufficient sterilization effect in a reliable manner and that can be implemented using simple equipment by reducing the heat resistance of heat-resistant spore-forming bacteria by the effect of decompression treatment in a high-pressure process, and by carrying out a heat sterilization treatment after a predetermined resting time has elapsed after the decompression to thereby sterilize and inactivate heat-resistant bacteria that have reduced heat resistance. A method for sterilizing or inactivating heat-resistant spore-forming bacteria by performing, as a pretreatment of a heat sterilization treatment, a high-pressure treatment in which a hydrostatic pressure of 50 MPa or more and 200 MPa or less is applied to an object under a temperature of 50° C.

Abstract: According to the present invention, there is provided a centrifugation dewatering apparatus that is capable of using a flow of air to dry a material to be dewatered while the material is being subjected to centrifugation dewatering. A centrifugation dewatering apparatus has a water-draining basket (2) for accommodating a material to be dewatered (i), and the water-draining basket (2) is rotatably provided to an apparatus main body (3). The water-draining basket (2) is rotatably driven, whereby water that has adhered to the material to be dewatered (i) is centrifugally removed. A hollow rotating shaft part (5) that is caused to rotate using a drive source (4) is vertically provided to the apparatus main body (3). The water-draining basket (2), which rotates in tandem with the rotating shaft part (5), is provided to a periphery of the rotating shaft part (5). The interior of the hollow rotating shaft part (5) and the interior of the water-draining basket (2) are provided in a communicating state.

Abstract: [Object] An object of the present invention is to provide an extremely practical and innovative food product heat treatment method capable of performing the same heat cooking and heat sterilization as that of the conventional technique while enhancing economy and productivity in comparison with the conventional technique. [Means of Achievement] The food product heat treatment method is characterized in comprising placing a food product (2) in a hermetically sealed vessel (1) in which a prescribed vapor pressure is maintained or can be maintained; injecting a heating liquid heated by a heating source (8) to 100° C.

Abstract: A process for producing a food enclosed in sealed containers which is free from a trouble during production that water spills from the containers or a perforating jig falls into the containers and in which a heat treatment can be conducted without causing quality unevenness. A food (1) is placed in containers (2). The containers (2) filled with the food (1) are sealed with a primary film (4) having a through-hole (3) to obtain a sealed-container-packed food (A). This sealed-container-packed food (A) is disposed in a heating vessel (7) having a steam inlet part (5) and a steam discharge part (6). Steam is introduced through the steam inlet part (5) into the heating vessel (7) to heat the sealed-container-packed food (A) while discharging the steam through the steam discharge part (6). Thereafter, a secondary film (8) is bonded to each container through the primary film (4) so as to cover the through-hole (3).
