How to build a 100 square atmosphere fresh-keeping cold storage

The air-conditioning fresh-keeping cold storage is effective in preserving the freshness of fruits and vegetables, ensuring the quality of fruits and vegetables without excessive consumption of electrical energy. Practice has also proved that both the storage and preservation period, as well as the guarantee of fresh quality, can have a good effect.

What are the components of the modified atmosphere cold storage?

Refrigeration equipment

When the Freon refrigeration system is used, the electric froth is sometimes used. It has been proved that the power consumption of the defrost method is quite large, and the fluctuation of the reservoir temperature is also large, which prolongs the cooling time. If the water is used for frosting, not only is the time for defrosting, but the temperature of the reservoir is very small, and the power consumption is less than 10% of the electric frost, which greatly reduces the power consumption of the cold storage.

Air conditioning equipment

In the air conditioning equipment, the main electric power is the oxygen reduction equipment. The oxygen reduction equipment is divided into two types, one is the high pressure nitrogen production mode, such as PSA variable nitrogen machine, hollow fiber membrane nitrogen generator; It is a vacuum system for vacuum production, such as a deaerator.

What are the characteristics of the atmosphere-controlled fresh-keeping cold storage? How to build a 100 square atmosphere fresh-keeping cold storage

1, for the general high-temperature cold storage difficult to store fruits and vegetables, such as kiwi, jujube, etc. can achieve excellent storage. Main performance indicators of modified atmosphere cold storage

2, fruits and vegetables stored in the atmosphere fresh-keeping cold storage, storage time is longer, generally 0.5-1.0 times longer than the ordinary cold storage, users can flexibly grasp the time of delivery, capture sales opportunities, create good economic results.

3, the atmosphere fresh-keeping cold storage creates a low-oxygen environment, which can inhibit the occurrence of pests and diseases of fruit and vegetable mold growth, and reduce the weight loss of fruits and vegetables to small.

4. The fruits and vegetables after leaving the warehouse maintain the original freshness and fragility. The moisture, VC content, sugar content, acidity, hardness, color and weight of fruits and vegetables are similar to the new picking state. The quality of fruits and vegetables is high and the market is competitive.

5, the fruits and vegetables stored in the air-conditioned fresh-keeping cold storage, after the storage, there is a process of conversion from the "sleep" state to the normal state, so that the swing period after the fruits and vegetables are out of the warehouse can be extended for 21-28 days, which is ordinary refrigeration. 3-4 times the library.
