摘要:
The boiler body (1) comprises a substantially cylindrical hollow skirt (8) made by extrusion, in particular of aluminium material. The extruded skirt (8) is machined on its surface to form seats for fastening of auxiliary elements such as doors, closing means, heating elements and the like, for the boiler and/or the steriliser. The skirt (8) is closed at one end by a plate-like bottom wall applied thereto and can have longitudinal stiffening ribs or ridges on the outer surface thereof. It preferably has a cross section different from the circular section, in particular a substantially oval section, to increase the useful space for arrangement of item-holding trays (6). At least the inner surface of the skirt (8) of aluminium material is anodised to withstand contact with steam.
摘要:
The device comprises an autoclave (2) defining a sterilisation chamber (3) for the items to be sterilised, and a single exhaust duct (13), provided with a cooling pipe coil (15a) and a suction pump (17) and through which the condensate, steam and exhaust air of the chamber (3) are caused to pass. The duct (13) discharges into an exhaust tank (14) disposed within the sterilizer container, and does not pass through the water-feeding tank (4) that is therefore devoid of a cooling pipe coil. The process involves at least one step of cooling the exhaust duct (13) and the pipe coil (15a) during evacuation of the sterilisation chamber (3).
摘要:
A moist-heat sterilization plant is provided which comprises a boiler shell (3), a chamber (4) inside said boiler shell (3), a heating block (14) external to said chamber (4) and in contact with the boiler shell (3), a feeding circuit (12) to supply the heating block (14) with water, and a conveying circuit (26) extending between the heating block (14) and chamber (4), the heating block (14) comprising canalization members (31) interposed between the feeding (12) and conveying (26) circuits and heating members (30) adapted to create a first steam flow through the canalization members (31). The process consists in admitting a first steam flow into a boiler shell, collecting the condensation water of the first steam flow and heating the boiler shell in such a manner that a second steam flow is produced from the condensation water.
摘要:
The process comprises an initial step involving suction of air from the autoclave, an intermediate step of introducing water into the autoclave and heating said water until a reference pressure (P r ), corresponding to the saturated-steam pressure at the sterilization temperature, is achieved therein, a sterilization step and a final step in which the autoclave is brought back to room pressure (P a ), heating being prolonged until a maximum pressure (P m ) higher than said reference pressure (P r ) is obtained in the autoclave and during said sterilization step at least one bleeding operation being carried out for ejecting air mixed with steam from the autoclave in a manner adapted to bring pressure from said maximum pressure (P m ) to said reference pressure (P r ). The plant comprises a boiler shell (3) forming a chamber (4) adapted to hold the objects to be sterilized, means (5) for controlling temperature and pressure in said chamber (4), water admitting members (16), pumping members (20) connected to said chamber (4) for carrying out suction, and bleeding members (21) adapted to operate a controlled relief when said chamber (4) is under conditions of at least partial pressurization.
摘要:
It is disclosed a closing device comprising grip means (9) and hooking means (10) to be engaged with each other and relatively movable along an approaching trajectory (11), the hooking means (10) comprising at least one holding element (12) drivingly movable along a locking trajectory (13) transverse to the approaching trajectory (11) and provided with a side wall (14) for engagement with the grip means (9) which has a main stretch (14a) extending obliquely between the approaching trajectory (11) and locking trajectory (13) and a final stretch (14b) structured as a niche.
摘要:
The apparatus comprises at least two discharge ducts (10, 11) to be selectively activated in succession. Disposed in the second discharge duct (11) are a condenser (19) and a vacuum pump or other suction means (21) that are not concerned with discharging of the condensate, said condensate discharging mainly taking place through the first discharge duct (10). Simultaneously with the condensate discharging, suction of air by the pump (21) is carried out and the vacuum is created in the second discharge duct (11), so that subsequent steam discharging and recondensing are promoted.
