The significance and preservation method of flower refrigeration

As a delicate agricultural product, flowers are not easy to transport and store. Since the respiratory function of the flowers is weakened after picking, the water of the flowers is easy to lose, and they will wither soon. Therefore, it is necessary to keep fresh after picking, so as to prolong the blooming time of the flowers.The use of cold storage has played an important role in the preservation of flowers today, so that flowers can still maintain a bright appearance for a long period of time after being picked. In this article, we will talk about the meaning and principle of flower cold storage and the temperature and humidity requirements of different flower varieties for cold storage.

Significance of flower cold storage

1. Flower cultivation can regulate the flowering period. Due to the variety of flowers or other reasons, flowers cannot be supplied as planned, which is undoubtedly a huge economic loss for merchants who cultivate and sell flowers. In this case, putting it in a flower cold storage at an appropriate temperature can delay its growth and development and make it bloom in time. For early-blooming flowers, moving them to cold storage can extend the flowering period by lowering the temperature. After the demand for flowers increases and the price increases, the flowers can be sold out of the warehouse to obtain more considerable profit margins.

2.At the same time, in order to meet the annual or multi-season supply demand of the flower market, the flowers can be stored in the cold storage, taken out and planted in batches, so as to ensure continuous supply and guarantee the annual supply of the market.

The principle of flower cold storage

On the premise of combining external thermal insulation materials, the flower cold storage uses refrigeration devices to regulate the temperature in the flower cold storage, and uses gas adjustment equipment or artificial lighting to keep the plants stored in the flower cold storage at a stable minimum physiological consumption, maintain the vitality of the plants, prolong their dormancy period, or maintain their fresh appearance. At present, there are two kinds of cold storage technologies for fresh flowers, namely, special fresh storage for fresh flowers and controlled atmosphere storage for fresh flowers.

The first technology is to use refrigeration equipment and heat-insulated warehouses for refrigeration and preservation, so that the temperature in the warehouse can be controlled at an appropriate temperature for fresh flowers to help them grow.

The second technology is to adjust the percentage of gas in the cold storage to reduce the oxygen content to below 6%, and raise the carbon dioxide to 3%~5% or even more than ten percent, thereby inhibiting the respiration of flowers and prolonging the preservation time of flowers.

Growth conditions of different varieties of flowers in cold storage

The storage temperature of flower cold storage refers to the temperature conditions required to maintain the freshness and moisture content of flowers. Due to the different storage places, varieties and storage batches of flowers, the storage temperature requirements of cold storage will also be different. During the storage process, too high or too low temperature will affect the quality and internal appearance of flowers, thereby affecting market sales and profits.

Under normal circumstances, the storage temperature requirements of the flower cold storage should be in line with the growth characteristics of the flowers. The temperature of the fresh-keeping cold storage for fresh flowers is usually between 0 and 12°C, and the relative humidity is 85% to 95%. 5°C is the best temperature for most flowers, because flowers can be stored more stably at this temperature, while reducing oxygen use and carbon dioxide emissions, which can reduce the degree of decay of plant tissues. Tropical flowers are kept at about 10-12°C, and frigid flowers need to be refrigerated at -5°C. On this basis, flowers with short flowering periods and large petals such as red roses should be stored at 12°C-16°C, while long-necked pot flowers (such as daffodils) should be stored at 15°C-18°C.

Through the above content sharing about flower cold storage, we can see that the popularization of flower cold storage is of great significance to improve the appreciation and economic value of flowers. On the one hand, consumers can buy beautiful flowers at all times, and on the other hand, it also enables sellers to reduce losses and increase flower sales profits, which greatly promotes the development of the flower industry.If you would like to learn more, please contact us at www.coldroomjl.com
