Product Description

The role of Bag Air Duct in the cold storage of fruits and vegetables

Cold Storage is a kind of storage method under the condition of lower than normal temperature but not lower than 0 °C. At present, cold storage is a kind of low temperature storage method widely used in vegetable cold chain logistics. Good quality of vegetables before transport and sale can be obtained by refrigeration.

Leafy vegetables are highly breathable after harvest, the water evaporates quickly, and the rate of water loss reaches 5% , which means that they lose their commodity value and are very vulnerable to mechanical damage. The quality of leafy vegetables was mainly affected by the internal and external factors, the external quality was mainly affected by chlorophyll, and the internal quality was mainly affected by ascorbic acid, Carotenoid and phenols. At present, low-temperature storage is one of the most effective methods to keep leafy vegetables fresh. Compared with 20 °C, lettuce stored at 0 °C could significantly preserve its quality, 0 °C significantly inhibited the content of soluble protein and sugar, the activity of Polyphenol oxidase and Peroxidase, and the accumulation of free amino acids in lettuce. The study on spinach and celery showed that the decomposition rate of chlorophyll and VC was slower than 9 °C under 4 °C environment. At the same time, the accumulation of nitrite can be effectively inhibited under the condition of 4 °C. Therefore, constant temperature and uniform airflow are two important indexes to evaluate the cold storage of vegetables.

It can ensure the uniform distribution of cooling capacity, improve the heat transfer efficiency, reduce the dry consumption of vegetables, improve the storage quality of vegetables and achieve the goal of energy saving. The cold air is transported to the working area at the speed of 0.07-0.18 m/S through a permeable air distribution pipe. When the ground cooling load is up to 300W/m ~ 2, the air supply pipe can realize the air supply without obvious sense of blowing, and the air supply is even as the surface air supply, can guarantee the very high temperature uniformity, creates the vegetable low temperature storage environment, prolongs the vegetable shelf life.
