When it comes to post-harvest quality, time and temperature control are everything. The moment leafy greens are harvested, they begin to lose moisture, texture, and nutrients. Rapid, precise cooling is the key to maintaining product freshness from field to shelf — and that’s where Facilities Management Group, LLC (FMG) delivers excellence.
As a Post Harvest Technologies Company, FMG provides mission-critical cold storage facility management, refrigeration contracting, and manufacturing, sales, service, and leasing of pre-cooling and refrigeration equipment. With decades of expertise in post-harvest cooling systems, FMG helps growers and shippers choose the best method for their specific crops and operations.
Vacuum Cooling: Fast, Efficient, and Ideal for Leafy Greens
For high-volume operations and delicate produce like lettuce, spinach, and herbs, vacuum cooling is considered the gold standard in pre-cooling. This method removes field heat by rapidly evaporating moisture from the surface of the leaves under low pressure — cooling the product evenly from the inside out.
Pros:
- Extremely rapid cooling — typically 15 to 45 minutes per cycle
- Maintains product integrity and minimizes dehydration
- Ideal for large-scale operations and extended shelf life
- Energy-efficient and environmentally friendly
Cons:
- Higher initial investment compared to other methods
- Requires specialized equipment and technical expertise
FMG manufactures and services advanced vacuum coolers designed to maximize throughput, reduce energy use, and preserve product quality. It’s a proven solution for customers seeking reliable, high-capacity pre-cooling performance.
Blast Chilling: A Flexible On-Site Cooling Option
For growers and distributors who need rapid, mobile cooling, blast chillers offer an efficient solution. These systems push cold air at high velocity across the product, reducing field heat quickly and uniformly.
Pros:
- Fast, adaptable cooling
- Mobile configuration allows setup close to the field or packing house
- Suitable for a wide variety of produce — not just greens
Cons:
- Less efficient than vacuum cooling for dense or large-scale loads
- Can cause dehydration in sensitive produce if not precisely controlled
FMG offers custom blast chiller systems that balance speed with temperature precision — perfect for facilities requiring on-site flexibility without permanent infrastructure.
Hydrocooling: Effective for Water-Tolerant Produce
Hydrocooling uses chilled, circulating water to quickly draw out field heat. It’s faster than traditional air cooling and cost-effective for specific crops like broccoli or leafy greens that tolerate water exposure.
Pros:
- Quick cooling process
- Can be cost-effective for certain commodities
Cons:
- Not suitable for all greens due to moisture sensitivity
- Requires strict sanitation and water management to prevent spoilage or contamination
FMG designs and maintains hydrocooling systems with optimized water circulation, temperature regulation, and filtration — ensuring clean, efficient performance
Forced-Air Cooling: Simple and Adaptable
For smaller or diversified operations, forced-air cooling remains a popular choice. This method uses fans to pull chilled air through palletized produce, removing field heat effectively in a controlled environment.
Pros:
- Works well in combination with cold rooms
- Enhances efficiency for small- to mid-scale operations
Cons:
- Risk of product dehydration if humidity isn’t managed carefully
- Less effective for high-surface-area produce like leafy greens
FMG provides custom forced-air systems tailored to facility size and crop type — integrating precision controls and humidity balance to ensure consistent results.
Expert Guidance for Every Cooling Challenge
No two crops — or operations — are alike. That’s why FMG engineers and technicians work directly with clients to assess their needs, design optimal systems, and ensure long-term performance. Whether it’s installing a vacuum cooling unit, upgrading an existing blast chiller, or managing a complete cold storage facility, FMG delivers solutions built on innovation, efficiency, and reliability.
With the right pre-cooling technology, farmers and distributors can protect product quality, reduce waste, and improve profitability — all while meeting global demand for fresh, nutritious produce.
