Case Study: Heavy-Duty Vegetable Vacuum Pre-cooler Delivered to Gansu Yongdeng Kangyuan

In the large-scale agricultural sector, managing the "golden hour" immediately following a harvest is critical. For leafy greens and dense vegetables like cabbages, natural cooling is simply too slow to prevent wilting and moisture loss. To guarantee maximum freshness and structural crispness, rapid field heat removal is required.

Ganzhou Dachang Cold Air Equipment Engineering Co., Ltd. recently completed a major project for Gansu Yongdeng Kangyuan Technology Development Co., Ltd., delivering a custom-built, high-capacity Vegetable Vacuum Pre-cooler tailored to their intensive agricultural output.

Let’s explore the scale and engineering of this heavy-duty industrial project through our deployment photos:

1. Engineered for Massive Agricultural Output

Ganzhou Dachang specializes exclusively in heavy industrial machinery, designed to handle immense throughput. As seen in the transport photo above, the sheer scale of this vacuum pre-cooler is a testament to its high-capacity design. Engineered specifically for major agricultural producers like Gansu Yongdeng Kangyuan, this unit is built to process tons of fresh vegetables per hour, keeping up with the high demands of peak harvest seasons.

2. Uncompromising Structural Integrity

Creating a rapid vacuum environment across such a large chamber exerts immense physical pressure on the equipment. The distinctive yellow exterior is heavily reinforced with thick steel ribbing. This rugged structural integrity ensures that the chamber will not warp or degrade over time, guaranteeing years of safe, stable, and continuous operation in demanding farm environments.

3. Precision Manufacturing and Seamless Assembly

Before deployment, every heavy-duty unit undergoes rigorous assembly and testing in our facility. The photo above highlights the careful integration of the reinforced chamber with the mechanical framework. This precision manufacturing guarantees a perfect, airtight seal once the heavy insulation doors are closed—the foundational requirement for rapid and energy-efficient vacuum cooling.

. The Powerhouse Refrigeration Core

The unmatched cooling speed of this equipment relies on the powerhouse mounted at the rear. Equipped with top-tier industrial vacuum pumps and high-efficiency compressors, the system rapidly drops the pressure inside the chamber. This causes the moisture on and just beneath the surface of the vegetables to evaporate at low temperatures, absorbing latent heat and uniformly cooling dense batches of cabbages from the inside out in a matter of minutes.

5. Real-World Cold Chain Integration

The ultimate test of our machinery is in the field. At the Gansu Yongdeng Kangyuan facility, the equipment seamlessly integrates into their daily workflow. Baskets of freshly harvested cabbages are staged directly in front of the wide-access doors, ready for rapid cooling. By instantly halting the respiration rate of the vegetables, our pre-cooler drastically reduces spoilage, minimizes weight loss, and ensures the produce remains crisp throughout the entirety of its cold chain journey.
