The process of VACUUM COOLING explained

Vacuum cooling is a pre-cooling method where the produce is cooled down by vaporizing moisture from inside the product itself. This vaporizing takes away energy in the form of heat from the product, and this ensures rapid cooling down, normally within 15 – 30 minutes for most products.

For products with a “high surface to weight” ratio like leafy salads, spinach, mushrooms, sprouts and flowers, vacuum pre-cooling is perfectly suited. But also other (more compact) produce like beans, broccoli, celery and sweetcorn, and perishable products like (straw)berries can quickly and efficiently be pre-cooled by using vacuum.
