Large Automatic Biscuit Production Line | Crisp Biscuit Machinery | Tunnel Baking Oven

This production line series can be customized to meet the client's site, biscuit, and process requirements. It can produce various types of biscuits by combining different molds and tunnel ovens with various types of energy, along with different formula and process techniques.

Rustic biscuits: Soda crackers, finger biscuits, animal crackers...

Crunchy Biscuits: Peach Biscuits, Caramel Biscuits, Oreo Biscuits...

Flexible Biscuit Machinery

Elastic biscuits, also known as "choux biscuits," are made from dough that requires fermentation. We recommend using a layering machine along with 3-4 sets of roller mills and a roller cutter for production. This method results in biscuits with a strong crisp texture, a smooth and even surface, and a layered cross-section, such as soda biscuits, animal biscuits, crisp biscuits, and finger biscuits, etc.

Equipment Principle: After the dough is mixed and fermented, it is fed through a stacker (optional), a three-roll feeder, and then passes through three roller calendering machines before being shaped by mold rollers. Any excess dough is separated by a wafer separator and returned to the first feeding machine. The shaped biscuit dough is then transported to the next baking equipment.

Crisp Biscuit Machinery

Crisp biscuits are made with a higher fat content, low-gluten flour, and sugar. These biscuits have a crunchy texture, forming less gluten during the dough mixing process, which gives them good plasticity and adhesion. Therefore, we recommend using roller printing machines for our clients, which can enhance the patterns and fun aspects of the biscuits. Common types include Peach Crisp, Oreo, Oatmeal biscuits, Caramel Butter biscuits, and more.

Equipment Principle: After the dough is rolled horizontally, it is directly conveyed to the crisp molding machine for roller embossing. The bottom of the conveyor belt features rubber rollers to enhance the grip between the mold roller and the conveyor belt, ensuring better printing and shaping of the biscuits. There is no excess waste. The biscuits can be directly conveyed to the撒布机 (salt sugar撒布机) and then into the oven for baking. Typically, the baking time required is slightly shorter than that for flexible biscuits.

Production Line Composition

The fully automatic biscuit production line integrates multiple advanced machines, achieving a fully automated production process from raw material mixing to finished product packaging. Key equipment includes:

Dough Mixers: Efficiently blend flour, sugar, fats, and other raw materials to form a uniform dough.

Dough flatting machine: Forms dough into even, flat sheets.

Biscuit Shaping Machine: Utilizes various molds to press and shape dough into different biscuit shapes.

Tunnel Oven: Equipped with electric, gas, or diesel heating options, ensuring even baking of biscuits.

Cooling conveyor: Cools baked biscuits to stabilize their texture.

Spraying Machine: Can apply oil or other coatings as required, enhancing taste and appearance.

Packaging Machine: Automatically completes the packaging of biscuits, preparing the product for distribution.

Working Principle

Dough Preparation: The dough mixer combines various raw materials into a uniform dough.

Dough sheeting: The sheeting machine presses dough into薄片of a set thickness.

Molding: The biscuit molding machine cuts the rolled dough into the set shapes using molds.

Baking: After shaping, the dough slices are baked in a tunnel oven, with precise temperature control ensuring even heating.

Cooling: Baked cookies are cooled on a conveyor belt to stabilize their texture.

Spraying and Coating: Optional spraying machines add flavor and luster to biscuits.

Packaging: Afterward, the packaging machine automatically completes the packaging process.
