Guizhou Moutai (Group) Blueberry Cold Storage Project
Multi-temperature cold storage for blueberry preservation and processing.
Guizhou Moutai (Group) Ecological Agriculture Industry Development Co., Ltd. operates a large-scale blueberry production and processing operation in Danzhai County, Guizhou, built around a 15,000-mu cultivation base and covering cultivation, fresh fruit sales, and deep processing — sold under the “Umeet” and “Yunshang Guoyuan” brands, online and offline.
Heshun provided the cold storage engineering for the facility — approximately 16,000 m² — supporting the blueberry chain from post-harvest cooling and fresh storage through sorting, freezing, and downstream processing.
Building the Cold Chain Around Fresh Blueberries
Fresh blueberries are sensitive to temperature and humidity after harvest — refrigeration alone is not enough for long-term storage.
The facility is therefore zoned by handling stage: pre-cooling and refrigerated storage at 0–4°C, quick-freezing at approximately -30°C, frozen storage at -18°C, sorting at 5–10°C, and controlled-atmosphere (CA) storage at 0–4°C — one continuous chain, not a single standard cold room.
Controlled-Atmosphere Storage for Fresh Fruit
The CA rooms required more than stable refrigeration. Temperature and humidity were controlled together with oxygen, carbon dioxide, and ethylene concentrations to slow blueberry respiration and metabolic activity.
A controlled atmosphere only holds if the rooms are truly airtight. The CA rooms used airtight structures with a three-layer adhesive and two-layer fabric sealing system, together with imported Italian equipment units.
Airtight construction, refrigeration, and atmospheric control together keep the storage environment stable and slow quality loss over long storage.
Connecting Preservation With Downstream Processing
The point was not just keeping blueberries cold — it was keeping the fruit usable for longer, so the processing line gets a steadier supply of raw material.
With all six zones under one roof, the flow runs from post-harvest handling straight through processing. That matters for products such as premium blueberry wine, where fruit quality and availability directly affect what comes out the other end.
