Abstract: A method for manufacturing frozen noodles including a step of subjecting raw noodles or dried noodles manufactured by an ordinary method to boiling treatment to produce boiled noodles containing moisture less than moisture of the noodles after cooking, a step of applying water to surfaces of the boiled noodles by sprinkling or dipping, a step of filling a freezing container with the boiled noodles having water applied to the surfaces and an ice lump containing frozen water, and a step of subjecting the boiled noodles to freezing treatment, in which the freezing treatment is started within 120 seconds from an end of the boiling treatment.

Abstract: A heat exchanger that performs heat exchange between a first fluid and a second fluid includes a first duct plate, a second duct plate, a flow path member, a caulking plate, an insertion projection, and a contact protrusion. The insertion protrusion protrudes from at least one of the first duct plate and the second duct plate toward the caulking plate, and is inserted into an insertion hole defined in the caulking plate. The contact protrusion protrudes from at least one of the first duct plate and the second duct plate toward the caulking plate, and is fixed to, and in contact with, a stopper wall of the caulking plate. A surface of the contact protrusion is in contact with a stopper plane wall when the contact protrusion is fixed to the frame member.

Abstract: An evaporator unit includes an evaporator configured to evaporate a refrigerant, and a capillary tube configured to decompress the refrigerant. The capillary tube has two longitudinal ends bonded to the evaporator. At least one position of a middle portion between the two longitudinal ends of the capillary tube is fixed to the evaporator by press-contacting the evaporator. Therefore, it can prevent a crack from being caused at the bonding portions of the two longitudinal ends of the capillary tube.
