Fully Automatic Shortcrust Biscuit Production Line——Reliable Forming and Tray Arranging Solutions for Industrial Pastry Manufacturing

In industrial pastry manufacturing, shortcrust biscuits require a delicate balance between structure, texture, and production efficiency. Traditional manual or semi-automatic methods often struggle to maintain product consistency while scaling output. The Fully Automatic Shortcrust Biscuit Production Line is designed to address these challenges by integrating precise dough forming, shaping, and tray arranging into a continuous and highly automated workflow.

This article introduces how each core machine in the line works together to ensure stable quality, flexible product design, and reliable high-volume production.

Production Challenges in Shortcrust Biscuit Manufacturing

Shortcrust dough is sensitive to heat, pressure, and over-processing. Common production issues include:

• Inconsistent dough thickness
• Loss of layered or crumbly texture
• Unstable product weight and shape
• Inefficient tray loading and manual handling

A well-designed automatic production line must preserve dough characteristics while ensuring efficiency and repeatability.

Line Overview: Integrated and Continuous Production Flow

The full automatic shortcrust biscuit production line typically consists of:

• Main Dough Forming Machine (OC-1510)
• Pinching / Pattern Forming Machine (OC-45)
• High-Speed Tray Arranging Machine (OC-860)

Each unit performs a clearly defined function while remaining fully synchronized with upstream and downstream processes.

Core Equipment and Application Value

1. Main Dough Forming: OC-1510 Three-Wheel Forming Machine

The OC-1510 serves as the core forming unit of the production line. Dough is first flattened by an adjustable large roller, then gradually processed through a planetary roller system composed of multiple small wheels and a main roller.

This progressive pressing method:

• Reduces stress on the dough
• Prevents heat generation
• Preserves traditional shortcrust texture

The final shaping roller and rolling mechanism produce uniform dough strips with controlled thickness. A photoelectric control system automatically adjusts roller speed, ensuring synchronized operation and high automation.

Application value:

• Consistent dough thickness and weight
• Flexible product specifications
• Stable output for continuous production

2. Pattern and Shape Forming: OC-45 Pinching Machine

After forming, dough strips are transferred to the OC-45 Pinching Machine for shaping and surface pattern creation. The machine features a 9-blade design with interchangeable food-grade blades, allowing manufacturers to create different round or patterned biscuit styles.

Key design highlights include:

• Independent conveyor speed control
• Adjustable lifting height for different products
• Automatic lubrication system for long-term stability

This machine enables high-speed shaping while maintaining clean edges and a uniform appearance.

Application value:

• Strong product differentiation through patterns
• Stable forming at 60–100 pcs/min
• Reduced downtime for blade maintenance

3. Automatic Tray Arranging: OC-860 High-Speed Tray Arranging Machine

The OC-860 completes the line by automatically arranging formed biscuits onto baking trays. Using a servo positioning system and fully computerized parameter management, the machine ensures precise placement and consistent spacing.

Arranging patterns can be customized:

• Single-row or double-row
• Parallel or cross arrangements
• Tray size-specific configurations

This eliminates manual tray loading, significantly improving hygiene and labor efficiency.

Application value:

• Accurate tray loading at high speed
• Flexible pattern customization
• Seamless connection to baking ovens

Why Automation Matters for Shortcrust Biscuit Lines

By integrating forming, shaping, and tray arranging into one continuous system, manufacturers benefit from:

• Consistent product quality
• Reduced labor dependency
• Improved production stability
• Easier scale-up for export-oriented production

The modular design also allows future expansion or product changes without redesigning the entire line.

Typical Applications

This production line is suitable for:

• Shortcrust biscuits
• Pastry-based cookies
• Traditional patterned pastries
• Custom-shaped baked products

Industrial bakeries, central kitchens, and professional pastry manufacturers widely use it.

Final Thoughts

The Fully Automatic Shortcrust Biscuit Production Line is not simply a collection of machines—it is a coordinated production system designed to preserve dough quality while delivering industrial-level efficiency. Through precise forming, flexible shaping, and automated tray arranging, it enables manufacturers to achieve consistent results and scalable output.
