How to adjust the temperature and humidity of fruit and vegetable storage

　　Fruit and vegetable storageMechanical refrigeration technology is used to artificially create a suitable and stable temperature environment for vegetables. Fruit and vegetable storage can greatly improve the shelf life and quality of vegetables. Controlled atmosphere storage: Controlled atmosphere storage is considered to be a modern and effective storage method. The storage principle of fruit and vegetable preservation is to put vegetables in a closed environment, and the refrigeration temperature is suitable. By appropriately reducing the oxygen content in the environment and increasing the carbon dioxide content, the life activities of vegetables centered on respiration and metabolism can be inhibited, so as to achieve the purpose of extending the storage period. There are currently two types of modified atmosphere (MA) and modified atmosphere (CA).

Leaf vegetables: storage environment: 0 ℃ ~ 4 ℃, not less than 0 ℃. Storage time: two days.

Step 1: Dispersed for 15 minutes.

Step 2: Spray a small amount of water quickly above the blade (do not spray water directly to the blade).

Step 3: try to wrap it as a whole, and be careful not to be too tight.

Step four: root down, after neatly arranged. Cover with plastic film and cover all sides tightly.

Step 5: Check every 24 hours. Note: Handle with care and pack after spreading.

Melons and fruits: preservation environment: about 10 ℃, not less than 7 ℃. Preservation time: depending on the degree of raw and cooked.

Step one: heat fifteen minutes to thirty minutes.

Step 2: wrap it in plastic wrap immediately.

Step three: spread out storage, do not squeeze. If you need to organize the pile, one-time neatly placed.

Step 4: Check every 24 hours.

Rhizome: Preservation environment: Keep in a cool place, not refrigerated. Storage time: about a week.

Step one: heat fifteen minutes to thirty minutes.

Step 2: Cut off the extra leaves

Step 3: wrap it in plastic wrap immediately.

Step four: spread out storage, do not squeeze. If you need to organize the pile, one-time neatly placed.

Step 5: Place in the shade after stacking with baskets, and cover with sunscreen if necessary.

Step 6: Check every 24 hours.

Beans: preservation environment: about 10 ℃, not less than 7 ℃. Storage time: 5~7 days

Step 1: Dispersed for 15 minutes.

Step 2: wrap it in plastic wrap immediately.

Step three: spread out storage, do not squeeze. If you need to organize the pile, one-time neatly placed.

Step 4: Check every 24 hours.

The water evaporation of fruits and vegetables is mainly caused by respiration. On the other hand, the environment of fruit and vegetable storage is too dry, that is, the air humidity of cold storage is too low; under normal circumstances, the humidity range of a reasonable vegetable storage is 85% ~ 90%. Of course, different kinds of vegetables have corresponding humidity. Before setting the temperature of the fruit and vegetable storage, you should also consult professional cold storage technicians to achieve preservation and power saving.
