ALLCOLD – Flowers Vacuum Cooler

Short Description:

Description of Vacuum cooler
Vacuum cooling is an ideal way to cool specific fresh cut flower, works by rapid evaporation of water from certain flowers under very low atmospheric pressures inside a vacuum chamber. Energy in the form of heat is required to change water from a liquid to a vapor state as in the boiling of water. At reduced atmospheric pressure in a vacuum chamber water boils at a lower than normal temperature.

Advantage of Vacuum cooler

(1) Keep the best quality of flowers and increase the flower’s life.

(2) The cooling time is short, generally about15- 20 minutes. Fast, clean and no pollution. 

(3) Can inhibit or kill botrytis and insects.Small damage on the surface of flowers can be ‘healed’ or will not continue to expand.

(4) The removed moisture accounts for only 2%-3% of the weight, no local drying and deformation

(5) Even if the flowers are harvested in the rain, the moisture on the surface can be removed under vacuum.

(6) Due to pre-cooling, the flowers can keep a longer storage.Also solves the logistical challenge.

Why we use vacuum cooler?

Vacuum cooling can be used on all types of flowers which need cold chain management i.e roses, carnations, gypsophila, pincushions and more. The right temperature with flowers improving cold chain management during transportation.This process is useful for clients who send their product to destination with a long transit times. Clients also will not have quality claims.
