Introduction: The Rising Global Demand for Core-Filled Puffed Snacks
In today’s competitive food processing industry, consumer preferences are rapidly shifting toward multi-textured, wholesome, and flavorful snacks. Among these, core-filled puffed snacks—such as crispy rice crackers filled with chocolate, cream, peanut butter, or savory cheese—have surged in popularity across North America, Europe, Southeast Asia, and the Middle East.
To help snack manufacturers meet this growing market demand while maintaining strict quality control and low operational costs, Jinan MT Machinery & Equipment Co., Ltd. delivers state-of-the-art Core Filling Puffed Snack Food Production Lines.
Recently, our continuous extrusion processing system was successfully commissioned and put into high-capacity production at a premier food processing plant in Vietnam. The field video above captures the line operating seamlessly, highlighting its robust stainless-steel architecture, automated ingredient delivery, precise core injection, uniform drying, and continuous seasoning capabilities.
In this comprehensive guide, we take a deep dive into the engineering, working mechanisms, technical advantages, and turnkey capabilities of Jinan MT Machinery’s flagship snack production system.
Comprehensive Process Workflow: From Raw Powder to Finished Crispy Snacks

1. High-Speed Raw Material Mixing System
The processing line begins in a designated mixing unit where cereal grains—such as rice flour, corn flour, wheat flour, oats, and starch—are evenly blended with water and liquid additives. The industrial stainless-steel mixer ensures thorough hydration and uniform particle distribution, which is critical for consistent puffing ratios during extrusion.
2. Closed Screw Conveying
From the mixer, raw materials are lifted via a sanitary, enclosed screw conveyor directly into the feeding hopper of the twin-screw extruder. This sealed transmission keeps the workshop environment clean, prevents dust explosion hazards, and ensures a steady material feed rate.
3. Advanced Twin-Screw Extrusion & Co-Extrusion Core Filling
At the heart of the plant is our high-performance Twin-Screw Extruder. Equipped with multi-zone heating barrels and precision-engineered screws, the machine subjects the flour mixture to high temperature, high pressure, and controlled shear forces.
Simultaneously, a dedicated Core Filling Machine injects liquid or semi-solid fillings (such as chocolate paste, fruit jam, cream, or savory pastes) directly into the hollow center of the extruded tube through a specialized co-extrusion die.
4. Precision Shaping, Pulling, and Cutting
As the co-extruded bar leaves the die, it moves into the automatic shaping and cutting unit. Here, specialized forming rollers seal both ends of the product to lock the cream/filling inside, prevent leakage, and cut the continuous bar into precise pillow, stick, bar, or rectangular shapes.
5. Multi-Layer Continuous Drying & Dehydration
Moisture control is essential for achieving the perfect crispy texture and extending shelf life. The cut snacks are conveyed into a multi-layer continuous drying oven (gas, electric, or steam-heated options available). The circulating hot air dries the snacks evenly from the inside out, reducing moisture content to below 3% without burning or scorching the delicate outer shell.
6. Automated Rotary Drum Seasoning
After drying, the crisps enter an inclined elevator feeding into a continuous stainless-steel Rotary Seasoning Drum. An automatic oil sprayer evenly coats the product surface, followed by a dry powder distributor that applies flavors such as BBQ, sour cream & onion, cheese, or seaweed powder. The rotating drum gently tumbles the snacks, ensuring 360-degree coverage without crushing or breaking the delicate puffed structure.
Key Technological Advantages of Jinan MT Machinery
Why do leading global snack processors choose Jinan MT Machinery over other equipment providers? The operational performance demonstrated in our Vietnam client facility highlights several critical advantages:
JINAN MT MACHINERY TECHNICAL HIGHLIGHTS
- Food-Grade SUS304 Stainless Steel Construction (Hygienic & Durable)
- Intelligent PLC Control Panel with Real-time Parameter Monitoring
- High Extrusion Precision & Zero Cream-Leakage Sealing Technology
- Energy-Efficient Drying Oven Design with Uniform Heat Recirculation
- Modular Twin-Screw Barrel Configuration for Easy Product Switching
1. Superior Hygiene and SUS304 Stainless Steel Design
As seen in the factory video, the entire line—including conveyors, hoppers, extruder frames, ovens, and seasoning drums—is built using food-grade SUS304/316 stainless steel. This rust-resistant material complies with international food safety standards (CE, ISO, FDA requirements) and allows for quick cleaning and sanitation procedures.
2. High Automation & Reduced Labor Intensity
The entire line requires only 2 to 3 operators to monitor parameters, check raw material hoppers, and handle final packaging. By replacing manual handling with automated screw hoists, continuous belt conveyors, and automatic temperature control cabinets, our customers drastically reduce labor costs and eliminate human error.
3. Precise Core Injection & Zero-Leakage Sealing
One of the main challenges in core-filled snack manufacturing is filling leakage during cutting and baking. Jinan MT Machinery’s proprietary die design and synchronized pulling/cutting machinery ensure that the internal filling remains perfectly centered and securely sealed inside each unit, minimizing scrap rates and product waste.
4. Superior Energy Efficiency & Thermal Optimization
Our multi-layer drying ovens are insulated with high-density silicate wool, reducing heat loss by up to 25% compared to conventional dryers. Furthermore, intelligent thermal recirculation systems ensure even heat distribution while optimizing fuel or electricity consumption.
5. Unmatched Versatility & Recipe Adaptability
By simply changing the extrusion die, screw profile, or shaping module, this exact same production line can produce a vast range of puffed snacks:
- Core-filled pillows, bars, tubes, and rolls
- Direct-expanded puffed balls, rings, stars, and corn curls
- Rice cakes, crispy cereal bars, and breakfast cereal flakes
