Abstract: A preferred method of the present invention includes the steps of: (1) providing a mass of dough; (2) providing a length of dough delivery conduit; (3) detaching a first portion of dough from the mass of dough; (4) delivering the first portion of dough into the dough delivery conduit; (5) detaching a second portion of dough from the mass of dough; (6) delivering the second portion of dough into the dough delivery conduit to form a stream of dough within the dough delivery conduit; (7) passing the stream of dough toward a dough piercing sharp for dividing the stream of dough, and; (8) forming the stream of dough into a plurality of dough pieces. Preferably, the step of delivering the portions of dough comprises utilizing a piston.

Abstract: A bakery dough flour applicator 10 for applying flour 12 to a dough piece 22 as the dough piece 22 travels along a processing path 134 includes a hopper 32 for supplying flour 12 and a transfer assembly 54 for providing flour 12 from the hopper 32 to an aerator 34 which creates an airborne flow of flour 40. The airborne flow of flour 40 is delivered to the interior of an enclosure 130 disposed about the dough processing path 134 through a plurality of spray nozzles 44 which direct the airborne flow of flour 40 to a dough piece 22 travelling through the enclosure 130 along the processing path 134 so that flour 12 from the airborne flow 40 adheres to the exterior surface of the dough piece 22. Flour 12 that does not adhere to a dough piece 22 is collected and filtered and provided back to the hopper 32 for later use.

Abstract: Bakery pans (10) are moved in edge-to-edge abutment along a dough processing line. The bakery pan indexer (36) (FIG. 5) includes a surface conveyor having an array of magnets mounted thereon. The magnets firmly attach themselves to the lower surfaces of the bakery pans (10) and positively control the movement of the pans through the dough ball delivery station (37), where the dough balls (25) are delivered to the dough receiving cavities (35) of the pans. The pans are maintained in constant motion, and the pans are accelerated and decelerated in order to compensate for the varying distances between the rows of dough receiving cavities of the pans.

Abstract: Dough shaping devices for shaping baker's dough pieces include a pair of cooperating shaping members, such as concave rounder bars (27) placed over a surface conveyor (16). The concave surface of the rounder bars is formed with a metal base plate (45) that includes a concave dough shaping surface (46) formed of stainless steel. Metal particles are formed on the dough shaping surface by the sputtering of metal plasma, to form a roughened texture, and a slick material, such as a fluropolymer, is applied thereover, to form a grainy but slick surface against which the dough pieces move. The grainy surface retards sliding friction of the dough pieces, while the slick surface permits immediate release of the dough from the dough shaping surface.

Abstract: A mass of baker's dough is delivered from hopper (28) through stuffing pump (30), developer (38), branch conduits (42-44), through metering pumps (46-48), to dough divider (55), where the streams of dough are divided into dough balls which drop to a rounder bar conveyor (60). The columns of dough are independently maintained from the dough divider (55) to the sheeter-molder-panner (24-26).

Abstract: A stream of dough passes from a metering pump (16) or (17) into the dough distribution manifold. The incoming stream of dough is sliced by the sharpened knife edge (64) of the divider knives (51) to form a pair of diverging streams of dough. Each diverging stream of dough is confronted with a second pair of divider knives (52) and (53), where a similar dividing function occurs. The positions of the knives are adjustable by external knobs (75) so as to balance the diverging streams of dough. The dough streams pass directly, in a line of sight, from the inlet openings (43) to the outlets (44A-44H), thereby avoiding the movement of dough about bends, turns, protrusions and obstructions which would deteriorate the gluten structure of the dough.

Abstract: Baker's dough moves from feed hopper (21) through dough inlet opening (25) into auger housing (19). Reduced pressure is maintained in the auger housing by gas exhaust port (28) and vacuum pump (27). The depth and amplitude of the helical cavity (31) in the pumping section (34) of the auger (20) is greater than the depth and amplitude of the helical cavity (33) in the gas exhaust section (35) of the auger, so that more resistance is applied by the interior cylindrical surface (29) of the auger housing to the dough in the gas exhaust section (35) than in the pumping section (34). Therefore, the dough does not clog the gas exhaust port, allowing increased vacuum to be applied to the housing, thereby firmly drawing dough to the auger. Additionally, transverse dough feed and transverse dough exhaust with respect to length of the auger tends to reduce the tendency of the dough to move circumferentially with the rotation of the auger, thereby enhancing the pumping efficiency of the auger.

Abstract: Divider blades (44) are mounted to rotary support plate (22), and the rotary support plate is moved in a circular path so as to cause the divider blades to move across the dough outlet openings (23), thereby severing the dough protruding from the outlet openings and forming dough balls (60). The divider blades are maintained in continuous contact with the face (18) of the dough delivery block (14), and the lower slicing edges (50) of each divider blade moves down to the lower horizontal edge (20) of the dough delivery block so as to make sure that the dough is not allowed to cling to the dough delivery block.

Abstract: Dough (20) is delivered in a stream through inlet conduit (29) to dough distribution chamber (60) of manifold (10). A spike (52) pierces the oncoming dough stream, and the dough flares radially into an annulus, past adjustable deflectors (42a-42f), and the dough is sliced by dough divider sharps (62) to separate the dough into individual streams of dough that move through delivery conduits (30a-30f). The velocity of dough moving through each delivery conduit (30a-30f) is controlled by the adjustable deflectors (42a-42f) which are positioned at the perimeter of the dough distribution chamber (60).

Abstract: Dough is moved by a screw conveyor (28) in the bottom of a hopper (12) through a hopper discharge opening (25) and through a discharge conduit (14). A wedge-shaped shield (58) is mounted in the lower portion of the hopper over the screw conveyor (28) and divides the dough moving down the hopper and guides the dough to opposite side of the screw conveyor and maintains an air passage (92) in the dough over the screw conveyor and in communication with the discharge conduit (14). A partial vacuum is drawn in the air passage (92) to evacuate gas from the dough.

Abstract: Dough is dispensed from the bottom of a dough hopper with a screw conveyor that slices into the dough mass and moves the dough horizontally out of a lower opening in the hopper and through a discharge conduit and discharge nozzle. The screw conveyor divides the conveyed dough into batches and the dough is worked in the discharge conduit and air from about the batches of dough is vented from the discharge conduit prior to extruding the dough through the discharge nozzle.

Abstract: A bread dough rounder bar for use with conventional dough dividing equipment to convert a dough piece into a rounded dough ball which may be subsequently processed into a bread bun or roll or the like. The rounder bar includes a work surface which varies in cross-section between an entrance section, a compression section and a rounding section.
