Every harvest tells a different story. From delicate blueberries to firm tomatoes, every crop demands a unique balance of temperature, humidity, and timing to stay at its best. But for growers working across seasons or remote locations, installing multiple systems for cooling and ripening can be costly and time-consuming.
That’s why ZGROUP designed its latest innovation — a mobile pre-cooling unit with an integrated ripening module. A containerized solution that lets growers rapidly cool blueberries during harvest and later ripen tomatoes with precision — all in one compact, mobile system.
Pre-Cooling: The First Step Toward Longer Shelf Life
At its core, the equipment functions as a high-performance pre-cooling unit, similar to ZGROUP’s systems already transforming farms across USA and beyond.
It uses a forced-air cooling process — the same technology used in professional postharvest facilities — to quickly remove field heat and moisture from freshly harvested fruit. Within minutes, warm blueberries coming in from the field are evenly chilled, locking in flavor, firmness, and appearance.
The results are immediate: faster cooling, better quality, and longer shelf life, even in warm climates or when transport takes hours to reach a packing house or cold room.
Enhanced Airflow, Food-Grade Design
Every ZGROUP pre-cooler is built for reliability in demanding environments. The system features:
- Food-grade interior finishes for safe handling and hygiene
- Optimized airflow to deliver uniform temperature across every pallet
- Low-maintenance controls that make operation simple for farm crews
- Flexible temperature and humidity settings to suit any crop
And because it’s a mobile containerized unit, it can be delivered, installed, and running in just days — with no need for construction permits in most cases.
Ripening Mode: Dual Functionality, Double Value
But what makes this unit truly unique is its integrated ripening module — turning the same equipment into a precision ripening room once harvest shifts from berries to tomatoes.
With advanced controls for temperature, humidity, and ethylene, growers can fine-tune the environment for uniform ripening. The transition between cooling and ripening modes is seamless — just a few adjustments on the intuitive control panel.
This flexibility allows producers to maximize equipment use year-round:
- Pre-cool blueberries, cherries, or other fruit during harvest season
- Ripen tomatoes, avocados, or plantains in the off-season
- Always maintain full control over product quality and timing
It’s versatility at its best, combining two postharvest technologies into one intelligent, mobile platform.
Innovation That Moves With You
Designed for on-farm use, packing houses, or remote growing areas, the ZGROUP Mobile Pre-Cooling & Ripening Unit offers a plug-and-play solution that brings industrial-grade performance wherever it’s needed.
Backed by ZGROUP’s expertise in modular cold storage and compatible with ZTRACK smart monitoring, this equipment provides full visibility over airflow, temperature, and performance — all accessible remotely.
From blueberries to tomatoes, it’s the same mission every time:
reduce waste, preserve freshness, and empower growers to take control of their postharvest process.
One Container, Endless Potential
By combining pre-cooling and ripening in a single mobile platform, ZGROUP helps producers eliminate postharvest bottlenecks, save energy, and make better use of resources — all while ensuring that every product, from farm to market, arrives in perfect condition.
Because freshness shouldn’t depend on location — it should depend on innovation.
Cool. Ripen. Deliver Fresh.
