Title: Apparatus for preparing edible products
Claims: What we claim is: 1. Apparatus for preparing an edible product including a cylindrical product core and an outer cylindrical shell of coagulated egg-white mass, said apparatus comprising: a plurality of vertically oriented cylindrical moulds, each formed by an integral cylindrical tube open at both ends, a bottom plug axially displaceable within each mould in sealing engagement with the inner mould surface, means for cyclically moving said moulds through a plurality of successive stations including a station for inserting a core member in each mould, a station for withdrawing the core member from the mould, at least one station for supplying liquid egg-white mass to the annular space defined between the inner wall of the mould and the core member, and supplying a material to form said product core to the space formed by the core member, and a station for withdrawing finished products from said mould, means for heating said moulds and means for subsequently cooling the moulds, lifting means adapted to move each bottom plug upwardly through at least the majority of the height of the associated mould for permitting withdrawal of the finished product from the top of the mould, means adapated to move each bottom plug back to its lowermost position in the associated mould, and applicator means for applying a measured amount of a lubricating agent onto the inner surface of each mould after the associated bottom plug has been lifted and the product withdrawn from the mould. 2. Apparatus as claimed in claim 1, wherein each bottom plug is provided with an upwardly directed scraper edge in tight engagement with the inner mould surface. 3. Apparatus as claimed in claim 1, wherein the bottom plugs are made of a material selected from the group consisting of plastics materials and synthetic rubber. 4. Apparatus as claimed in claim 1, wherein said applicator means comprises a vertically displaceable carrier rod associated with each of a plurality of moulds, an applicator member carried by the lower end of each said rod, means for lowering said carrier rod into said mould and lifting it out of the mould after the finished product has been withdrawn from the mould, and means for effecting a volumetric proportioning of said lubricating agent to said applicator member during the motion cycle of said carrier rod. 5. Apparatus as claimed in claim 4, wherein said proportioning means includes a separate pump associated with each applicator member. 6. Apparatus as claimed in claim 4, wherein the lower end of said carrier rod is adapted to push the bottom plug downwardly within the mould. 7. Apparatus as claimed in claim 6, further comprising abutment means protruding inwardly below each mould for defining the lowermost position of the bottom plug. 8. Apparatus as claimed in claim 4, wherein said applicator member is a pad made of a spongy material and having a cross-section larger than the internal cross-section of the mould, whereby the pad is radially compressed when it is moved through the mould. 9. Apparatus as claimed in claim 8, further comprising a distributor cup mounted above said pad for distributing the lubricating agent. 10. Apparatus as claimed in claim 9, wherein said distributor cup is formed with a plurality of distributor ducts evenly spaced along the circumference thereof. 11. Apparatus as claimed in claim 8, further comprising a guide member secured to said carrier rod below said pad for radially guiding the rod in the mould. 12. Apparatus as claimed in claim 11, wherein the guide member is shaped as a spider. 13. Apparatus as claimed in claim 4, further comprising scraper means secured at the upper face of each applicator member and spring biased outwardly into engagement with the mould surface. 14. Apparatus as claimed in claim 1, further comprising rotary brushes supported by said bottom plug lifting means and engaging the inner mould surfaces below the bottom plugs during the lifting thereof.
