Industrial Core Filling Snacks Processing Machine

How It Works: Precision-Driven Automation

1. Raw Material Preparation & Mixing: The process begins with a high-shear mixer that blends grain flours (corn, rice, wheat, quinoa, etc.) with water, sugar, and other additives to create a uniform dough for the outer shell. Simultaneously, fillings (chocolate, cream, jam, peanut butter, cheese paste, etc.) are prepared in a separate melting or mixing tank to achieve the ideal viscosity for smooth injection.
2. Precision Feeding & Co-Extrusion: A loss-in-weight precision feeder delivers the prepared dough to a twin-screw extruder, which cooks and shapes the dough into a hollow shell under high temperature and pressure. At the same time, a specialized core filling system injects the prepped filling into the center of the hollow dough—synchronized perfectly to ensure no leakage or uneven filling.
3. Shaping, Sealing & Cutting: The filled dough moves to a shaping and cutting unit, which pinches the dough to seal the filling securely and cuts it into customizable shapes (pillows, bars, sticks, hearts, or custom molds). This step ensures each snack has a consistent size, shape, and sealed edge to prevent filling leakage during subsequent processing.
4. Drying, Seasoning & Cooling: After shaping, the snacks pass through a multi-layer drying oven (electric or gas-powered) to reduce moisture content, enhance crispness, and extend shelf life—without melting the inner filling. Optional seasoning equipment (single/double drum or octagonal seasoning machines) can add oil, flavor powder, or coatings for extra taste. Finally, the snacks are cooled to room temperature, ready for packaging.
5. Automated Control & Monitoring: The entire process is controlled by a PLC touch screen (Siemens) with real-time monitoring, allowing operators to adjust parameters (temperature, filling volume, speed, shape) easily. Advanced models include AI-driven adjustments for dough consistency and filling accuracy, ensuring consistent quality across every batch.

Applications: Versatile for All Core-Filled Snack Types

• Sweet Core-Filled Snacks: Chocolate-filled pillows, cream-stuffed cereal bars, jam-filled pastries, fruit paste-filled puffs, and chocolate praline bars.
• Savory Core-Filled Snacks: Cheese-stuffed crackers, meat paste-filled sticks, and savory cream-filled extruded snacks.
• Health-Conscious Options: Whole-grain core-filled bars, low-sugar fruit-filled snacks, and protein-rich cream-filled treats (using quinoa, oats, or legume flours).
• Customizable Variations: Adjust molds and recipes to produce snacks of different sizes (small bite-sized to large bars), shapes (pillows, tubes, hearts, custom designs), and filling ratios (10%-50% filling content) to meet specific market needs.

Key Advantages: Why Choose Our Core Filling Processing Machine?

• High Efficiency & Large Output: Equipped with a powerful twin-screw extruder and automated workflow, the machine delivers high throughput (100-500 kg/h, depending on model) to meet industrial-scale production demands. It reduces production time by 30% compared to semi-automatic equipment, maximizing your daily output.
• Precision Filling & Consistent Quality: Advanced filling depositors ensure accurate filling volume (error ≤±0.5%) and uniform distribution, eliminating under-filled or over-filled snacks. The synchronized co-extrusion and sealing system prevents filling leakage, while the PLC control system maintains consistent temperature, speed, and shape across every batch—protecting your brand reputation and consumer trust.
• Food-Grade Safety & Durability: All contact parts (mixer, extruder, conveyor, filling system) are made of 304/316 stainless steel, complying with FDA, CE, and ISO food safety standards. The alloy steel screws feature a self-cleaning, modular design, preventing cross-contamination and extending the machine’s service life. The control cabinet uses 24V safe voltage for added operational safety.
• Versatility & Flexibility: A true “all-rounder” machine—turn off the core filling function and change the die mold to produce standard plain puffs (balls, rings) or non-filled snacks, maximizing your production flexibility. It supports a wide range of fillings (liquid, paste, semi-solid) and raw materials (grains, starches, legumes), allowing you to quickly adapt to market trends and launch new products.
• Cost-Saving Automation: Fully automated operation reduces the need for manual labor (only 2-4 workers required per line), minimizing labor costs and human error. Energy-efficient designs (e.g., recirculating air drying ovens) reduce gas/electricity consumption by up to 30%, while low maintenance requirements lower long-term operational costs.
• Easy Operation & After-Sales Support: The user-friendly PLC touch screen allows operators to set parameters, monitor production, and troubleshoot easily—no professional technical skills required. We provide detailed English operation manuals, video tutorials, on-site installation/commissioning, and a 1-year warranty, plus lifelong after-sales service for parts replacement and technical support.
