Solar natural drying is a method that slowly dries noodles using natural sunlight and heat. Unlike rapid mechanical drying that removes moisture at high temperatures, this process allows moisture to dissipate gradually—preserving the inherent elasticity and flavor of rice and wheat ingredients. As a result, the noodles achieve a firm, chewy texture while significantly reducing the air pockets, dryness, and dull mouthfeel commonly associated with mechanical drying.

To fully realize these advantages, Chilkab designed and built its own indoor solar drying facility, allowing sunlight to pass through while maintaining controlled conditions. While conventional fuel- or hot-water-based drying systems offer higher productivity, they often compromise noodle texture. Chilkab addressed this limitation by reinterpreting traditional sun-drying methods used in old mills through a modern, industrial lens. From design to operation, the facility represents a rare and unprecedented approach, completed only after extensive trial and refinement.

The results are clear. Chilkab’s solar natural drying system has earned the only HACCP certification of its kind in Korea, and is widely regarded as a one-of-a-kind facility not only domestically but globally. This certification validates the rigor of Chilkab’s quality and safety management, and serves as a key reason consumers consistently perceive a difference in noodle texture.

There are also significant advantages in production and sustainability. Solar drying operates without fuel costs, supports increased output through large-scale drying, and works in tandem with automated packaging lines to reduce overall production expenses. Moreover, the process generates no heat emissions or exhaust gases, enabling environmentally responsible manufacturing. The trade-off is time: while mechanical drying can be completed within 24 hours, solar drying requires approximately 48 hours and demands operational expertise to manage slower cycles and weather variability.

In summary, solar natural drying is a demanding process that simultaneously delivers superior taste and texture, safety, and environmental sustainability. By developing dedicated facilities in-house, Chilkab has overcome its challenges—securing a distinctive advantage in noodle quality and reinforcing its brand differentiation.
