Short Answer¶

Potato storage is a critical link in the year-round supply chain for potato flake and powder manufacturing. Properly managed storage facilities maintain raw material quality for 8-10 months post-harvest, enabling consistent production regardless of growing season. Key storage challenges include sprout inhibition, reducing sugar accumulation (low-temperature sweetening), humidity control, and disease prevention. Hongji Agriculture's storage infrastructure combines controlled atmosphere technology, real-time monitoring systems, and evidence-based reconditioning protocols to ensure stable raw material quality throughout the storage season.
