What are the matters needing attention in the preservation of kiwi fruit in the fresh-keeping warehouse of fruits and vegetables

　　Fruit and vegetable storageSave the kiwi need to pay attention to matters:

1. The suitable storage temperature of kiwifruit is about 0 ℃;

2. Before the kiwifruit is put into storage, it should not be put into storage too much at one time, generally 10%-15% of the total amount is preferred;

3. The temperature in the fresh storage of fruits and vegetables should not change significantly;

4. When kiwifruit is taken out of the warehouse, if the temperature outside the warehouse is too high, the buffer room should be used to gradually heat up to avoid water droplets on the surface of the fruit, causing the fruit to rot.

5. The humidity in the fresh storage of fruits and vegetables should be adjusted between 90% and 98%;

6. Kiwi fruit storage period to the fruit and vegetable fresh-keeping warehouse ventilation;

Refrigeration unit selection:

The temperature setting range of kiwi fruit cold storage is 0~6. Generally, semi-closed piston type high temperature refrigeration unit is used, which has the advantages of large refrigerating capacity, universal accessories and convenient follow-up maintenance. If the cold storage unit is large, it is recommended to use a water-cooled unit; if the unit is small, an air-cooled unit can be used, and the condensation area needs to be increased; if it is a large kiwi cold storage unit, it is recommended to use a parallel or screw machine.

Selection of insulation board for fresh storage of fruits and vegetables:

Generally, 10cm thick polyurethane color steel plate is used. The assembled refrigeration board is more hygienic and beautiful, and the refrigeration door needs to be designed according to the actual situation.

Refrigerated evaporator options:

Kiwifruit in the fruit and vegetable preservation of the evaporator is particularly important. Because the water content of kiwi fruit is large, try not to put it in the wind. Therefore, the internal evaporator of fruit and vegetable storage should not choose air cooler, recommend aluminum coil. The aluminum coil is characterized by fast cooling speed and no wind flow, which reduces the moisture of kiwi fruit as much as possible. As for the condensed water, when we make the aluminum plate, we will make an integrated ditch under the aluminum plate, and drain the warehouse as the ditch flows to the water tank to prevent water droplets from condensing on the kiwifruit.

Kiwifruit should be refrigerated after picking, such as stored in the cold storage of ordinary fruits and vegetables fresh storage or better effect of modified atmosphere fruit and vegetable fresh storage cold storage, in order to extend the storage period, to create more considerable economic income. Kiwifruit cold storage technology is to ensure that the relative humidity of kiwifruit cold storage temperature can be maintained at 90% ~ 95%, the gas component O2 content is 2 ~ 4%, the gas component CO2 content is 5%, and the cold storage temperature of kiwifruit is kept at 0 ℃ ± 0.5 ℃. It is worth noting that there must be no ethylene gas in the cold storage of kiwifruit, so it is also determined that kiwifruit must be stored separately, especially not mixed with bananas, apples and other fruits to avoid mutual ripening. Kiwifruit can be stored for 4-6 months in the cold storage of fruits and vegetables, and the quality meets the standard. If the use of modified atmosphere storage storage of fruits and vegetables, the storage period is generally up to more than half a year.
