Apparatus and methods for the production of three-dimensional food

Abstract

Three-dimensional food products such as crackers, cookies, puffed snacks, puffable glassy half-products, pet foods, pasta, confections such as chewing gum, and ready-to-eat cereals are produced on a mass production basis by feeding a dough or other food composition to a plurality of dies which shape it into ropes. The shaped extrudate ropes obtained from each die are cut by a cutting device which passes across only a portion of each of the orifices of the dies to partially cut each of the shaped extrudate ropes. The cutting device passes across the entire orifice of each of the dies to completely cut each of the partially cut extrudate ropes into individual pieces. The use of a multi-port extrusion die permits higher mass flow rates and thus greater dough piece production rates at lower cutter speeds. The use of multi-port extrusion and lower cutter speeds increases shape, definition, and accuracy of cutting and reduces scattering and deformation of the individual pieces. The plurality of extrudate ropes are preferably cut simultaneously. The plurality of dies may be fed by a calendar press or preferably an extruder. In embodiments of the present invention, the cutting means may be arranged or mounted on a continuous band, a reciprocating or oscillating cutter which moves in a closed path, or a rotating shaft. The doughs which are cut into three-dimensional pieces may be raw, partially cooked or baked, or fully cooked or expanded. In the production of three-dimensional crackers, the amount of water and enzymes are used to increase the expandability or leavening ability of extruded cracker doughs.
