Title:
METHOD FOR PRESERVATION OF FRESH PLANTS BY VACUUM PRE-COOLING SYNCHRONOUSLY COMBINED WITH MODIFIED ATMOSPHERE TECHNIQUE
Document Type and Number:
WIPO Patent Application WO/2017/157057
Kind Code:
A1
Abstract:
Disclosed is a method for the preservation of fresh plants by vacuum pre-cooling synchronously combined with modified atmosphere technique. The method comprises the following steps: (1) screening the field-picked fresh plants; (2) placing the screened individuals in a vacuum pre-cooler for pre-cooling; (3) after being pre-cooled to the final temperature, the device automatically shuts down the refrigerator and vacuum pump, and passing the pre-configured mixed gas from the intake air inlet into the vacuum chamber for re-pressing; (4) taking the re-pressed fresh plant out of the pre-cooler, performing modified atmosphere packaging and refrigerating. The method is such that a specific mixed gas is filled during the vacuum pre-cooling and re-pressure stages, and the re-pressure process after pre-cooling is closely integrated with the modified atmosphere technique, significantly prolonging the shelf life of the product for more than 5 days.
