  • Patent number: 9451782
    Abstract: The invention is a depositing device for depositing flowable food containing gas comprising a pressurized feed N line conveying flowable food containing gas under pressure into the food; piston means operatively connected to the feed line comprising a piston and a chamber; an outlet to deliver food at the atmospheric pressure into molds. The device comprises a pressure retaining means arranged to retain the product in the chamber at the same pressure as the line pressure and to deliver the product through the outlet as pressure in the chamber increases from the line pressure upon descent of the piston in the chamber.
    Type: Grant

  • Patent number: 9400056
    Abstract: An apparatus for depositing a liquid, semi-liquid or semi-solid food product. The apparatus comprises a fixed volume chamber for receiving the food product under a positive pressure, the chamber being defined by chamber walls, one of the chamber walls being provided with an outlet orifice for depositing the food product, the outlet orifice being provided with a first sealing surface. The apparatus also comprises a valve spindle arranged for reciprocating movement within the chamber, the length direction of the valve spindle extending substantially perpendicular to the chamber wall in which the outlet orifice is provided, a first end of the valve spindle being provided with a second sealing surface. The second sealing surface of the valve spindle is arranged for abutting the first sealing surface of the outlet orifice to thereby close the outlet orifice.

  • Patent number: 6051267
    Abstract: A chocolate or other fat-containing confectionery material is fed into and extruded from a screw extruder and the temperature of the extruder barrel wall and screw are controlled so that the material advanced through the extruder and the product from the die are non-pourable and so that the product is plastically deformable for a period of time, and in particular, the screw and barrel wall temperatures are controlled so that the screw has a temperature higher than the barrel wall temperature. Additionally, the material may be advanced within an extruder barrel wall which is roughened and the diameter of the screw root may increase in and along the direction of material advanced in the extruder.
