Definitions

  • the present invention has for its object an improved apparatus for the thermal treatment of products and notably of food products contained in sealed holders, such as for example tinned foods; the thermal treatment is necessary for the sterilization and, preferably, the continuous cooling and heating of the treated tins.
  • the sealed containers are introduced into tubular baskets, travelling along a circuit through treating enclosures, these baskets being conveyed by means of link-chains, these chains constituting end obturators for the perforated baskets which are open at their ends, thereby facilitating the filling and discharging operations.
  • the chains comprise side-plates welded on the hinge pins pivoted in sockets also fast with the side-plates of the intermediate links, these intermediate links and their sockets being, preferably, obtained by casting.
  • the side-plates welded tothe pins are formed on one side with an extension of the pin and carry, in addi tion, insert studs surrounding the pin and formingtherewith a kind of spoon on which, in a stable manner, rest the baskets, these spoons facilitating the clearing of turns if any in the path imposed to the baskets.
  • the obturating chains pass round guide wheels in the turns and are inserted in guide-tracks, obtained preferably by bending sheetmetal elements, these sheet metal elements being, in addition, so shaped as to also constitute a guide-track for the basket ends.
  • the latter consist of ribbed sockets conveniently engaged on. the terminal portion of the perforated cylindrical walls which form the baskets.
  • the present invention also relates to,a sterilizing apparatus comprising the above defined obturating and conveying means.
  • the conveying path passes through a chamber, in which water steam under pressure is fed, the inletandoutlet of this chamber resulting from the through passage of hydraulic joints which, in addition to their sealing effect, constitute heating and cooling means for the products treated.
  • the vconveying circuit passes through an enclosure filled with heated water under pressure, the filling. of this enclosure with hot water occurring by draw ng water from ,a compensating reserve the volume of wiich is at least equal to that ,of the bodies intro pokerd into the enclosure by the conveyor, when the latter is fully loaded, said compensating reserve being fed itself by the overflow of said enclosure; this enclosure under hydraulic pressure communicating with a tower acting [as a cooler through .the medium of presssure-gas insulating cap.
  • Both embodiments, of such an apparatus comprise, moreover, according to the present invention, a station wherein the perforated baskets are successively extracted from the conveying chain, emptied, filled and re-introduced into'the transporting circuit, the extracting, emptying, filling and introducing steps being controlled synchronously;
