Korea’s Only HACCP-Certified Solar Natural Drying

2026-01-05











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


carefully 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.​
