In the magical world of snack production, every crispy and sweet wafer roll embodies the dual craftsmanship of technology and artistry. With the innovative design of "dual-track parallel operation," the HG Double-Head Wafer Roll Machine transforms wafer production into a assembly-line ballet that balances efficiency and deliciousness. Let's unveil the entire process of how this sweet snack comes to life.
The First Encounter of Ingredients: Precise Proportioning and Blending
Making wafer rolls is to weigh and proportion ingredients such as flour, sugar, eggs, and oils according to an exclusive recipe. These "cornerstones of deliciousness" are poured into a 30L large-capacity mixer (slurry mixer), where a blade-type agitator starts at a constant speed. Like the arms of a dancer flipping rapidly, it blends liquid and solid ingredients into a smooth and uniform slurry within 2-3 minutes, laying the foundation for the crispy texture of wafer rolls.
Dual-Track Baking: The Synchronized Magic of Double Heads
The core of the HG Double-Head Wafer Roll Machine—two independent baking heads—operate like twin craftsmen, launching the baking process in sync:
- Slurry Feeding and Coating: The slurry is precisely divided by the slurry feeder to the heating hubs of the two heads. A sophisticated flow control system ensures the slurry thickness on each hub has an error of no more than 0.5mm, like draping a uniform "thin veil" over the hubs.
- High-Temperature Shaping: The heating hubs rotate and bake at a constant temperature of 180-220℃. The slurry rapidly solidifies into golden-brown crispy sheets, emitting a mixed aroma of egg and caramel. The baking cycle for a single head takes only 40-60 seconds.
Rolling and Filling: Detail Control in Dual-Track Operation
When the wafer sheets are baked, the "dual-track magic" of the double heads enters a critical stage:
- Path for Hollow Wafer Rolls: One head is equipped with a core rolling shaft. After the soft wafer sheet is scraped off by a blade, it is immediately rolled into a hollow cylinder around the smooth shaft. The cutting device then precisely cuts it to a preset length (e.g., 10cm), and the hollow wafer rolls slide into the conveyor belt through an inclined chute, waiting to cool.
- Path for Filled Wafer Rolls: The other head a filling machine. At the moment the wafer sheet is scraped off, filling materials (such as chocolate sauce or cream cheese) are injected into the inner side of the sheet through pipes. Simultaneously, the core rolling shaft drives the sheet to roll, completing filling and rolling in sync. This ensures the filling is evenly distributed inside the wafer roll, avoiding leakage or unevenness.
Cooling and Conveying: Efficiency Assurance via Dual Lines
Wafer rolls produced by the two heads fall onto two independent conveyor belts respectively:
- The air-cooling system on the conveyor belt blows 15℃ low-temperature air onto the wafer rolls, reducing their temperature from the baking temperature to below 40℃ within 30 seconds, quickly shaping them and locking in their crispy texture.
- The end of the conveyor belt is equipped with a sorting device, which automatically screens according to types (hollow/filled) and length errors. Unqualified products are removed, while qualified ones are neatly arranged, ready for the packaging process.
Core Advantages of Dual-Track Production: Coexisting Efficiency and Flexibility
The "dual-exit" design of the HG Double-Head Wafer Roll Machine disrupts traditional production models:
- Doubled Output: A single device can produce 2,000-2,500 wafer rolls per hour, equivalent to the capacity of two single-head machines, saving 50% of the equipment floor space.
- Flavor Freedom: It can simultaneously produce original-flavor hollow wafer rolls and strawberry-filled wafer rolls, or adjust baking temperatures to achieve texture differences, meeting diverse market demands.
- Hygienic and Convenient: The independent disassembly design of the double heads allows the filling system and baking components to be quickly disassembled for cleaning, complying with food-grade hygiene standards. The single cleaning time is shortened to 15 minutes.
From slurry to finished product, the HG Double-Head Wafer Roll Machine guides every wafer roll through a scientific journey of "synchronized baking-differentiated rolling-dual-line cooling" with its precise dual-track process. This is not just a snack production process but also a balancing art of efficiency and deliciousness—when two wafer rolls of different flavors are "born" from the dual exits simultaneously, the sweet production line becomes the stage for the collision of technology and cuisine.
