US 4,958,556 A · Filled cracker making apparatus

Abstract

Baked goods and in particular hard biscuits and crackers which are hollow and which are adapted to contain a filling are inverted subsequent to baking so that the biscuit or cracker can have a filling inserted therein from the side of the biscuit or cracker that had been contacting the bottom of the oven. It is preferred to insert a filling by means of needle injection into hollow biscuits and crackers through the side that had been in contact with the bottom of the oven since the other side in many instances will contain a fanciful design. The baked hollow forms as they emerge from the oven are inverted by being flowed to a wheel containing longitudinal stepped sections which upon rotation deposit the baked hollow forms on a lower conveyor belt in an inverted form. The hollow baked and inverted forms are then moved to an indexing mechanism which holds the hollow baked forms while they are pierced by a needle and filled with a desired filling.

Dependent claims

An apparatus for producing filled hard biscuit products comprising:

(a) means to mix a dough;
(b) means to form said mixed dough into a plurality of dough forms;
(c) oven means to bake said dough forms to produce essentially hollow baked forms wherein the baked forms have a top surface and a bottom surface;
(d) first conveyor means to convey said baked forms from the oven means;
(e) a baked form inverter means to receive the baked forms from said first conveyor means and to invert the baked forms;
(f) second conveyor means to convey the inverted baked forms from the inverter means;
(g) a holding means to receive the inverted baked forms from the second conveyor means;
and
(h) a plurality of filling needles that move vertically downwardly and upwardly and fill each inverted baked form in said holding means wherein said holding means holds said inverted baked forms in a stationary position during filling and releases the filled baked forms when the filling needles move upwardly.

6 more elements

An apparatus for producing filled hard biscuits or crackers comprising;

(a) oven means to bake a dough form to produce substantially hollow baked forms, said baked forms having a first side facing upwardly having embossed or printed indicia thereon, and second side facing downwardly;
(b) first conveyor means to transfer the baked forms in an upright position from the oven means;
(c) inverter means to receive the baked forms from the first conveyor and to invert the baked forms, wherein the inverter means comprises a continuously rotating wheel having a plurality of stepped sections thereon and positioned to receive said baked forms from said first conveyor whereby rotation of said wheel causes said baked forms to fall from said wheel in an inverted position;
(d) a second conveyor means disposed to receive said baked forms from the inverter means in an inverted position;
(e) an indexing mold disposed to receive the inverted baked forms from said second conveyor and being moveable between upward and downward positions, wherein said indexing mold holds the inverted baked forms in a stationary position for a predetermined period of time when in a downward position and releases the baked forms when in an upward position;
(f) a plurality of filling needles moving vertically upwardly and downwardly, said needles cooperating with said indexing mold whereby needles move downward and penetrate the hollow baked forms through said second surface to inject a filling composition into said hollow baked forms when the indexing mold is in said downward position and holding the baked forms, and whereby said needles move upward in cooperation with the upward movement of the indexing mold;
and
(g) a third conveyor means to receive the filled baked forms released from the indexing mold.
