Jinan MT Machinery Successfully Installs High-Capacity Core-Filling Rice Snack Production Line in Indonesia

Jinan MT Machinery & Equipment Co., Ltd., a global leader in advanced food extrusion technology, has announced the successful installation and commissioning of a customized, high-capacity Core-Filling Rice Snack Production Line at a prominent food manufacturing facility in Indonesia.

Designed to meet the rapidly growing Southeast Asian market demand for puffed snacks, this state-of-the-art processing line integrates three heavy-duty twin-screw extruders working in tandem. The successful turnkey project underscores Jinan MT Machinery’s engineering capability in delivering high-volume, automated snack production systems tailored to international food safety and quality standards.

Meeting the Growing Demand for Core-Filling Rice Snacks in Southeast Asia

The puffed snack market across Southeast Asia—particularly in Indonesia—is experiencing accelerated growth, driven by evolving consumer snacking habits, urbanization, and high demand for ready-to-eat puffed rice snacks. Core-filling rice snacks, known for their crispy grain shell and rich creamy or savory centers (such as chocolate, cheese, peanut butter, or matcha), demand precise temperature control, uniform extrusion, and accurate filling injection.

To achieve continuous high-yield output without compromising product crispiness or filling balance, the Indonesian client partnered with Jinan MT Machinery to engineer a multi-extruder high-capacity production facility.

“Our client in Indonesia required a solution that could scale up production significantly while maintaining supreme product quality and operational stability,” stated a senior project engineer at Jinan MT Machinery. “By deploying three high-efficiency main twin-screw extruders operating in a synchronized parallel configuration, we provided a customized processing system capable of delivering massive hourly output with minimal operational downtime.”

Complete Production Flow: From Raw Material to Finished Snack

The newly installed core-filled rice snack production line represents a fully automated, continuous processing workflow engineered for maximum thermal efficiency and minimal manual intervention. The entire production line consists of several integrated processing stages:

1. Raw Material Blending and Preparation

The process begins in the raw material preparation zone. High-speed stainless steel mixers uniformly blend rice flour, corn flour, wheat flour, and essential ingredients with a precisely controlled moisture content. The batch mixer operates alongside automated vertical elevators and screw feeders to ensure consistent powder density before entering the extrusion phase.

2. Automated Conveying & Distribution

Once homogenized, the flour mixture is elevated via stainless steel incline screw conveyors. A central overhead distribution channel evenly distributes the raw materials into three dedicated volumetric hoppers attached to the main twin-screw extruders.

3. Parallel Twin-Screw Extrusion & Core Injection (The Core Stage)

At the heart of the production line are three advanced Twin-Screw Extruders operating side-by-side:

• High-Shear Cooking & Puffing: Inside the extruder barrels, raw starches undergo intense thermo-mechanical shearing, cooking, and gelatinization under controlled pressure and temperature zones.
• Dual-Core Injection Systems: Simultaneously, dedicated co-extrusion center-filling machines inject liquid or paste fillings (such as chocolate cream or cheese paste) directly through specialized dual-layer extrusion dies into the core of the expanding rice tube.
• Co-Extrusion Die Technology: This ensures uniform wall thickness for the crisp outer rice shell while perfectly encapsulating the inner filling without leakage.

4. Shaping, Cutting, and Pillow Formation

Upon exiting the extruders, the continuous filled tubes immediately enter a multi-functional shaping and cutting machine. Depending on market requirements, the cutter shapes the extruded tubes into core-filled pillows, bars, tubes, or round bites, while securely crimping both ends to seal in the creamy filling before baking.

5. Multi-Layer Industrial Drying & Roasting

The formed snacks are continuously conveyed into a multi-layer continuous drying oven. Powered by energy-efficient heating elements and recirculating hot air, the oven gradually reduces product moisture to below 3%. This critical thermal process develops the signature crispy, crunchy texture of premium rice snacks while significantly extending shelf life.

6. Continuous Rotary Seasoning & Oil Spraying

After baking, the hot snacks transition onto an incline conveyor leading to an automated rotary drum seasoning line. Liquid flavor sprayers and dry seasoning powder dusters evenly coat the rotating snacks without breaking the delicate outer crisp shells.

7. Multi-Fan Air Cooling and Automated Packaging

Finally, the seasoned core-filled snacks travel along a multi-fan cooling conveyor, lowering the product temperature to ambient levels before transferring directly to automatic multi-head weighing and flow-wrap packaging systems.

Key Advantages of Jinan MT Machinery’s Extrusion Line

The newly commissioned line in Indonesia demonstrates several distinct technical advantages that establish Jinan MT Machinery as a trusted equipment manufacturer worldwide:

1. High Output via Triple-Extruder Architecture

Unlike traditional single-extruder arrangements, incorporating three heavy-duty main extruders allows the production plant to achieve exceptional hourly capacity. This modular design also allows the factory to run one, two, or all three extruders simultaneously depending on daily production plans.

2. Superior Flexibility and Versatility

The twin-screw extruder design allows easy adjustment of screw configurations, barrel temperature profiles, and cutter speeds. Food manufacturers can easily switch raw materials (rice, corn, wheat, oats) and produce various shapes (pillows, rolls, sticks, balls) or flavor combinations on a single production line.

3. Energy-Efficient & Food-Grade Stainless Steel Construction

All product-contact surfaces and main structural frames are fabricated from high-grade stainless steel (SUS304/SUS316), conforming strictly to international CE and ISO hygiene standards. Advanced thermal insulation on the multi-layer drying oven minimizes heat loss and lowers total power consumption.

4. Advanced PLC Smart Control System

Equipped with an intuitive PLC touch-screen control panel, operators can monitor and fine-tune critical parameters—including screw speeds, barrel heating temperatures, cutter speeds, and feeding rates—in real time, guaranteeing batch-to-batch consistency and reduced labor overhead.

Turnkey Installation & Global After-Sales Support

Beyond equipment manufacturing, Jinan MT Machinery delivered complete end-to-end engineering support for the Indonesian client:

• Custom Factory Layout Design: Engineered equipment layout tailored to the client’s plant floor area and production workflow.
• On-Site Installation & Commissioning: Overseas service engineers were dispatched to the Indonesian facility to supervise mechanical installation, electrical connection, and test runs.
• Operator Training & Formulation Assistance: Local plant staff received comprehensive training on machine operation, daily maintenance, troubleshooting, and snack formulation adjustments.
