    • 1448515 Aseptic slicing of food MICARNA AG FLEISCHWARENFABRIK 6 July 1974 30046/74 Heading A4C [Also in Division F4] Bulk foodstuffs are sliced by a reciprocable rotating blade 4 located in a housing 6 which is fed with sterilized heated air through a pipe 7, the air being between 200‹C and 350‹C to maintain the blade at a sterilized temperature of between 100‹/and 135‹C. Cooled sterilized air from a hose 21 is supplied to a pivotable hood 8 located over the bulk foodstuff secured on a slide and driven towards the blade by a motor driven screw 25. An ultraviolet lamp may be located in hood 8 with a further lamp directed towards the underside of a conveyer belt 14 on which the cut slices are fed to a packaging machine. The pressure in housing 6 and hood 8 is greater than ambient pressure to prevent penetration of non-sterile ambient air. Air is supplied through a duct 41, Fig. 3, to a cylindrical pre-heater 40 containing electric coil heaters 42, 43 and then to a main heater 18 which includes a spiral electric heating element 48, a tubular filter 49, a further heater 51 and an outlet duct 50. Heated air from the duct 50 passes through pipe 7 to housing 6 and via a valved duct 52 to a cooling unit 53 in which the air is cooled by passing over water pipes 55 before passing out through hose 21 to the hood 8. The Specification also discloses heating blade 4 by electric resistance heating, induction heating or flame heating.
