Sales of the ready-to-heat foods with cooked rice aseptically packed have increased manyfold in Japan over the past 10 years. Cooked rice aseptically packed is better taste and higher quality, as compared with retort-pouch cooked rice. KAGOME DELI that was started to sale from 1999 by KAGOME Co., Ltd., was very unique in microwave oven cooking foods. It was made up of the cooked rice aseptically packed and the retort-pouch cooking sauce (eg. for Risotto, Chicken Rice, and Doria). Consumer could cook these using a microwave oven during two minutes only, and take in the low-calorie (lower 300 kcal/menu). In this report, two technical considerations were suggested on the development process of KAGOME DELI. These were (1) microorganism control, (2) package development, for cooked rice aseptically packed. To improve safety of the cooked rice aseptically packed, it is preferable that cooked rice is adjusted pH 4.9 or below and 5.0% or more oxygen concentration of head space. And higher usability package for cooked rice was able to be developed by understanding the relation between the strength of sealing and peeling.

Provided is a plate heat exchanger that includes a plurality of heat transfer plates stacked to each other, a gasket interposed between each adjacent heat transfer plates, and a regulating member formed to be able to support at least partially the gasket. Each heat transfer plate has a fitting recessed portion formed in recessed manner on the side on which the gasket fitting groove is formed. The fitting recessed portion crosses the recessed strip while extending along the gasket fitting groove. The support part is arranged along the gasket fitting groove when the regulating member is held in fitting engagement with the fitting recessed portion. The support part is arranged along the gasket fitting groove when the regulating member is held in fitting engagement with the fitting recessed portion.

A flow-path forming gasket is interposed between peripheries of each adjacent ones of stacked heat transfer plates; communicating-path forming gaskets are each installed, surrounding the passage holes in each adjacent ones of the heat transfer plates alternately; and thereby a first flow path adapted to pass a high-temperature fluid, a second flow path adapted to pass a low-temperature fluid, and communicating paths adapted to cause the fluids, respectively, to flow in and out of the first and second flow paths are formed alternately on opposite sides of each heat transfer plate. A drain hole is formed in each of the heat transfer plates to discharge fluid leaking from the first flow path, the second flow path, or the communicating path. The drain hole is surrounded by gaskets isolated from the first flow path, the second flow path, or the communicating path. A leakage flow path or a leakage collector is formed by the gaskets.

Heat transfer plates are stacked, each being provided with a plurality of passage holes, a flow-path forming gasket is interposed between peripheries of each adjacent ones of the heat transfer plates, thereby alternately forming a first flow path to pass a high-temperature fluid, a second fluid to pass a low-temperature fluid, and communicating paths to cause the fluids to flow in and out of the first flow path and the second flow path on opposite sides of each heat transfer plate, and communicating-path forming gaskets surrounding the passage holes are interposed between adjacent ones of the heat transfer plates, thereby forming a communicating path to cause a fluid to flow in and out of the first flow path and a communicating path to cause a fluid to flow in and out the second flow path. Each communicating-path forming gasket is made up of inner and outer gasket members arranged in two lines, the inner gasket member surrounding the passage holes while the outer gasket member surrounding the inner gasket member.
