Provided is a hot isostatic pressing (HIP) device that improves the heat uniformity of a hot zone during a pressurization process of an object being processed. This HIP device (100) is provided with: an outer casing (4) having an open outer opening part (4H); an inner casing (5) having an open inn opening part (5H); a heat-insulating body (R) disposed between the outer casing (4) and the inner casing (5); a gas flow generation part (30); and a plurality of first gas conduits (12), A hot zone (P) in which a pressurization process is performed is formed inside the inner casing (5). During the pressurization process, a low-temperature pressurization medium gas which has been generated by the gas flow generation part (30) and has passed through the first gas conduits (12) moves upward in an inner flow passage (L1) between the casings, and then flows into the hot zone (P) from the inner opening part (5H), Even when the pressurization medium gas leaks from the vicinity of a bottom all part (20) and flows into the hot zone (P), the heat uniformity of the hot zone (P) is maintained.

A method (100) for pressing at least one article in an arrangement as well as a pressing arrangement (500). The method comprises providing an article inside a load compartment and feeding a pressure medium into the pressure vessel and increasing (140) the pressure in the load compartment; increasing (120) the temperature and maintaining (150) the increased temperature and the increased pressure for selected periods of time (t.sub.1, t.sub.2); changing (170) the temperature from the first predetermined temperature level to a second predetermined temperature level (T.sub.2); feeding (180) a carbon-containing gas into the pressure vessel; maintaining (190) the second predetermined temperature level for a selected period of time (t.sub.3); reducing (200) the temperature in the load compartment; and discharging (210) the pressure medium from the pressure vessel and reducing (220) the pressure in the load compartment.

A device for producing meat products includes an assembly formed from a plurality of walls maintainable in a fixed relationship to one another during a joining operation, surfaces of the plurality of walls defining work surfaces disposed to surround raw pieces of meat placed therein to be joined. A drive mechanism is configured to drive the assembly, which can form a cooking container such as a cooking box, along a first axis in a reciprocating movement of at least 10 mm along the first axis at frequency of at least 1 Hz and to drive the assembly along a second axis in a reciprocating movement of at least 10 mm along the second axis at frequency of at least 1 Hz, wherein the first axis and the second axis are angled with respect to each other, and the drive mechanism drives the assembly at different frequencies along the first and second axes.

A method for processing at least one article in a pressing arrangement is provided. The method comprises the steps of: increasing the temperature in the load compartment by the at least one heating element in the furnace chamber; maintaining the increased temperature at a predetermined temperature level, T.sub.1, for a selected period of time, t.sub.1; and during the steps of increasing the temperature and maintaining the increased temperature, circulating the pressure medium within the pressure vessel by the at least one flow generator.

A powder compaction mold includes a die and upper and lower punches configured to fit into the die and is configured to compress a powder between the upper and lower punches to manufacture a powder compact. Of the members forming the powder compaction mold, at least one of two members in sliding contact with each other has therein a vent passage through which gas is vented from a filling space for the powder surrounded by the die and the lower punch to an outside of the powder compaction mold. The vent passage has a gas intake port that is open to a clearance section formed between the two members and connecting to the filling space.
