Biscuit Equipment Manufacturing Machine

Biscuit Shaping
Die-cutting Shaping: Place the dough on the conveyor belt of the die-cutting forming machine. Then, press the dough into biscuit blanks of various shapes by means of mold stamping.
Roller Printing Shaping: The dough is evenly fed by the feeding roller into the space between the two relatively rotating rollers of the roller printing forming machine. One of the rollers has concave patterns of biscuits on its surface. The dough is pressed into these concave patterns, and the excess dough is scraped off by a scraper to form biscuit blanks.
Extrusion Shaping: For some soft doughs, an extrusion forming machine is adopted. Under the action of the screw propeller, the dough is extruded through molds with different shaped holes to form biscuit blanks of various shapes. Then, a cutting device cuts them into appropriate lengths.
Biscuit Baking
Preheating and Loading into the Oven: Before the biscuit blanks enter the oven, the oven needs to be preheated to reach the set baking temperature. Place the formed biscuit blanks evenly on baking trays or conveyor belts and then send them into the oven.
Baking Process: In the oven, the biscuit blanks go through different baking zones, generally including a heating-up zone, a constant temperature zone, and a cooling-down zone. In the heating-up zone, the biscuit blanks heat up rapidly, the moisture evaporates quickly, and the starch gelatinizes and proteins denature. In the constant temperature zone, the inside of the biscuits continues to undergo the Maillard reaction and others, forming the unique color and flavor of the biscuits. In the cooling-down zone, the biscuits are gradually cooled to prevent the surface from getting overly burnt.
Removing from the Oven and Cooling: After baking is completed, the biscuits are taken out of the oven and placed on cooling racks or conveyor belts for natural cooling or air cooling. During the cooling process, the moisture inside the biscuits is further evenly distributed, making the biscuits taste crisper.
