Abstract: The apparatus for making a filled tubular food product in which tubular dough pieces are extruded onto a supporting die member which maintains the internal diameter of the cavity in the dough piece fixed during raising and baking after which the cavity in the baked dough piece is filled with another relatively softer food product.

Abstract: A portable device for making donuts and the like which includes a batter extruder, a cooking scroll into which the extruded batter is received, a heating element underlying the scroll for heating the cooking medium introduced therein for cooking the extruded batter, a circulation pump for circulating the cooking medium in which the extruded batter is carried through the scroll, a temperature regulator for regulating the temperature of the cooking medium in the scroll, a flow controller for controlling the flow of cooking medium through the scroll, and a conveyor for evacuating the finished product from the scroll. The extruder and flow controller are synchronized, whereby a continuous stream of raw batter may be introduced into the cooking medium and cooked therein.

Abstract: A donut making appliance includes upper and lower electrically heated grids movable into and out of mating engagement along first surfaces. Each of the first surfaces of the grids includes a predeterminedly placed annular recess having a central core. Upon bringing the grids into engagement, the recesses are aligned to define a toroidally shaped cavity in which cake or the like batter is placed for baking donut shaped cakes. The central core of the lower grid defines a well preferably having the shape of a truncated cone, open at the first surface of the grid. The central core of the upper grid comprises a plunger having a shape complementary to that of the well and extending outwardly from the first surface of the grid, for receipt in the well upon engagement of the grids. The plunger-well arrangement ensures the alignment of the recesses and the displacement of cooking oil deposited in the well upon bringing the grids into engagement.
