Vacuum cooler for vegetables
Compact vegetables like broccoli, asparagus, beans, broccoli and celery can be cooled well by a vacuum cooler for vegetables. If the system is designed well, it can compete on price & performance with (ice)water cooling, reducing the risk for contamination at the same time. And only a vacuum cooling process can give you a perfect homogenous cooling result!
As the surface-to-weight ratio of the compact vegetables in not very high, cooling speed will be slightly lower, 30 – 45 minutes is a normal cycle time, for dry produce it can even be slightly longer. The benefit of the longer cooling times is the fact that you will need less installed cooling power, and that a homogenous cooling is guaranteed.
For compact vegetables, larger size systems normally are more effective, and the more time is available for cooling, the better the system that can be designed. For most produce it is advised to include a water spray system (Hydrovac).
