Guangzhou Central Kitchen: Vacuum Cooling 2 Tons of Braised Food Daily
A 10,000-meal/day central kitchen in Guangzhou replaced blast chillers with a CVF-500 food vacuum cooler, cutting cooling time from 3 hours to 18 minutes per batch.
The Challenge
A Guangzhou central kitchen producing 10,000 meals/day for corporate canteens faced a severe bottleneck at the cooling station. Three blast chillers running 16 hours/day could barely keep up with 2 tons of braised meat and vegetable dishes. HACCP compliance was borderline — core temperature took 3+ hours to reach 10°C.
The Solution
We replaced three blast chillers with a single CVF-500 food vacuum cooler. The unit processes 500 kg per batch, cooling from 90°C to 10°C in 18 minutes.

Customer Feedback
“We were skeptical that vacuum cooling could handle 2 tons of braised food daily. After 6 months of operation, we’d never go back to blast chillers. The food quality is better, the energy bills are lower, and the health inspectors are happy.” — Head Chef & Operations Manager, Guangzhou
