Abstract
The invention provides a cut flower precooling method, which is characterized in that10 - 15 percent of water is evenly sprayed on the surface of the cut flower after the cut flower is placed in order; then the cut flower is put into a container of water, with the stalk of the cut flower immersed in the water by 2 - 4 cm; finnaly the cut flower is put into a vacuum chamber for a vacuum cold treatment and taken out when the lowest temperature of the cut flower reaches 2 DEG C. The invention has the advantages that cut flower precooling method can increase the cooling speed, reduce the loss of moisture, and prolong the life of the flower arrange in the vase; more particularly, the cut flower precooling method is suitable for the preservation and cold storage of mass cut flowers.
Description
Technical field
The present invention relates to flowers refrigeration field, particularly a kind of cut-flower forecooling method.
Background technology
China constantly increases the demand of flowers at present, and is also more and more higher to the requirement of its freshness and quality, therefore adopts new and high technology to make the post-processing technology of adopting of flowers fruits and vegetables attain a new height extremely urgent again.Traditional usefulness chemical substance (as antistaling agent, bactericide) is adopted the method for post processing and is abandoned, because this way is refused by the international market.Vacuum pre-cooling technology has in China and uses, and further improves and the expansion range of application but still need.
Summary of the invention
The objective of the invention is to improve the quality of the process of circulation of flowers, evenly the water of 10-15% is shone in spray on its surface, puts into the container that fills water, make scape immerse in the water 2-4 centimetre, put into vacuum chamber, carry out the vacuum cold treatment, when cut-flower temperature lowest part reaches 2 ℃, take out.Major advantage of the present invention is that the speed of raising cooling reduces drying loss, has prolonged a bottle slotting life-span, is particularly useful for cut-flower cold storing and fresh-keeping in enormous quantities.
Technical scheme of the present invention: a kind of cut-flower forecooling method, it is characterized in that, after cut-flower is neatly put, evenly the water of 10-15% is shone in spray on its surface, puts into the container that fills water, makes scape immerse in the water 2-4 centimetre, put into vacuum chamber, carry out the vacuum cold treatment,, take out when cut-flower temperature lowest part reaches 2 ℃.Major advantage of the present invention is that the speed of raising cooling reduces drying loss, has prolonged a bottle slotting life-span, is particularly useful for cut-flower cold storing and fresh-keeping in enormous quantities.
When carrying out the vacuum cooled processing, the floral leaf of cut-flower and scape place are inserted with temperature sensor, can observe variation of temperature.In the vacuum cooled processing procedure, the vacuum chamber pressure of vacuum cooled machine should be not less than 613Pa, in case local temperature is low excessively, it is freezing to make that flowers produce.
This scheme advantage: the speed that has improved the flowers coolings; Handle spray and shine water, reduced drying loss; Prolonged a bottle slotting life-span.Preserved original quality of flowers to greatest extent.
