Thin Rice Cakes and Rice Chips: Producing Less-Than-2mm Crunch
While classic rice cakes are usually 8–12 mm thick, the market is now embracing thin rice cakes and rice chips with thicknesses below 2–3 mm. These products offer:
- A chip-like crunch
- Faster flavor impact
- Lower calorie per piece
To produce them reliably, you need a line built around precision popping, mould design and drying.
1. What Makes Thin Cakes Different?
In thin cakes and chips:
- Mass per piece is lower, so small process deviations have bigger effects.
- Cell structure is more fragile, increasing breakage risk.
- Moisture and oil management become critical for crispness and shelf life.
Standard rice cake machines can’t always deliver this; specialized lines are needed.
2. Mould and Popping System Requirements
To achieve less-than-2mm thickness:
- Mould cavities are shallower and may include specific venting patterns.
- Popping pressure and heating profiles must be tuned for rapid expansion without over-drying.
- Mechanical tolerances must be tight to keep thickness consistent.
B&F Engineering’s rice cake lines leverage adjustable pressure and recipe memory to maintain the fine balance required for thin products, while mould design is tailored to each thickness target.
3. Drying, Cooling and Seasoning
Thin cakes and chips typically require:
- Short but precise drying steps to reach target moisture.
- Carefully designed cooling and conveying to avoid cracking.
- Seasoning systems that respect the fragile structure—often with optimized drum angles, speeds and nozzle placement.
Optional oil spray or slurry systems can enhance flavor while keeping fat content lower than traditional fried chips.
4. Packaging and Handling
Because thin products are more delicate:
- Conveyors and transfer points must minimize falls and impacts.
- Packaging formats may use smaller bag volumes or protective trays.
- Case packing and palletizing must be tuned to avoid compression damage.
B&F considers these factors in the overall line layout, ensuring that every station—from popping to palletizing—supports the integrity of thin cakes and chips.
Conclusion
Thin rice cakes and chips open new possibilities in the better-for-you snack category—but only if the line is engineered for precision. With specialized moulds, advanced process control and gentle handling, B&F Engineering helps brands deliver ultra-crispy, low-fat puffed snacks that rival traditional chips.
