Apparatus and method for forming two component food product
View Patent ↗A method and apparatus for forming molded food products having an outer first component and an inner second component is provided. The apparatus includes a pressurized supply of first component and a pressurized supply of second component. A mold housing extends along a first direction. A first end portion and a second end portion are arranged to be movable along the first direction within the mold housing and to be separated by a pre-selected distance along the first direction. An injector tube is in fluid communication with the supply of pressurized second component. The first and second end portions are arranged to be contained within the mold housing in a fill position to form a mold cavity within the mold housing around the injector tube. The mold cavity has an inlet in fluid communication with the supply of pressurized first component when in the fill position to receive first component to form a shell having an inside void. The injector tube provides a pathway for the pressurized second component into the inside void of the shell to fill the inside void with the second component to complete a two-component molded food product.
1. A method for forming a molded food product having a first component surrounding an inner, second component, comprising the steps of:
arranging a mold cavity defined by an outer wall and an inner tube, said inner tube having an open end, and two end wall portions spaced apart and positionable within the outer wall;
filling the mold cavity with a first component forming a shell having an inside void;
relatively retracting the inner tube along a first axis with respect to the mold cavity and filling the inside volume occupied by the inner tube with the second component through the inner tube and out of the inner tube open end to complete the molded food product, wherein at least one of said first and second components is a food product; and
moving the end wall portions along the first axis to a position wherein the molded food product is outside the outer wall to remove the molded food product.
2. The method according to claim 1 , wherein the inner tube open end is relatively movable with respect to the end wall portions only to positions at or between the end wall portions.
3. The method according to claim 2 , wherein the outer wall is stationary and the end wall portions are formed on rods which are configured to slide within said outer wall.
4. The method according to claim 1 , wherein said inner tube is movable with respect to the outer wall.
