Air inflated air conditioning storage is one of the most advanced fruit and vegetable preservation facilities in the world. It can control the temperature and humidity in the warehouse, but also control the content of oxygen, carbon dioxide, ethylene and other gases in the warehouse, and inhibit the physiological activity of fruits and vegetables by controlling the air composition of the storage environment, so that the fruits and vegetables in the warehouse are in a dormant state. The practical application proves that the use of air conditioning storage to store fresh fruits and vegetables, both from the storage of fresh period, or from the fresh quality of fruits and vegetables have reached the best effect, which is incomparable to other storage methods.

First, the characteristics of air inflated air conditioning storage

1, the fruit and vegetables stored in the air conditioning warehouse, the storage time is longer, generally 0.5-1.0 times longer than the general cold storage, the user can quickly grasp the storage time, capture sales opportunities, and create the best economic effect.

2, after the storage of fruits and vegetables to maintain the original freshness and brittleness, fruit and vegetables moisture, VC content, sugar, acidity, hardness, color, weight and other new picking state is almost the same, high quality fruits and vegetables, with market competitiveness.

3, the fruits and vegetables stored in the air conditioning warehouse, after the storage of a dormant state to the normal state of the transformation process, so that fruits and vegetables after the storage can be extended 21-28 days, is 3-4 times the general cold storage.

4, air conditioning fresh storage is made of a low oxygen environment, can inhibit the growth of fruit and vegetables mold and the occurrence of diseases and pests, so that the weight loss of fruits and vegetables is reduced to a minimum.

5, for the general high temperature cold storage difficult to store fruits and vegetables, such as kiwi, dates and so on can achieve excellent storage effect.

Second, important performance indicators of air conditioning fresh storage

Temperature in the warehouse: -2 ℃ ~ 15℃ adjustable. Relative humidity: RH75% ~ 95% adjustable. Oxygen content (O2) : 1% ~ 10% adjustable. Carbon dioxide (CO2) : 1% ~ 10% adjustable. Ethylene content: less than 10PPM. The airtight index of the storage body (domestic) : the limited pressure is 10mm water column, and the residual water column height is not less than 5mm after 10min. The airtight index of the storage body (foreign) : the limited pressure is 25mm water column, and the residual water column height is not less than 8mm after 30min.

Third, air conditioning fresh storage equipment

Air conditioning storage equipment is mainly composed of the following parts:

(1) Refrigeration equipment (ammonia system, freon system and glycol system, etc.)

(2) Humidification equipment in the warehouse

(3) defrosting and cooling water equipment of refrigeration unit in the warehouse

(4) Intelligent control equipment

(5) Air conditioning equipment (nitrogen machine, carbon dioxide removal machine, ethylene removal machine and sulfur dioxide generator, etc.)

(6) Air inflated equipment (gas regulating body, inflation equipment).

Fourth, the assembly of gas storage

1. Complete the construction of civil engineering below the floor insulation layer in the air inflated storage.

2. Complete the assembly and construction of the air inflated membrane.

3. Complete the construction of the air conditioning warehouse.

4. Complete the construction of civil works below ±0.000 (including ground, insulation layer, waterproof steam insulation layer, etc.).

5, the library body air tightness leak detection, positive pressure acceptance.

6. Acceptance of the overall project of the air conditioning warehouse.

The application of advanced air rib structure technology in the air inflated cold storage has excellent performance in the aspects of space air tightness, storage body insulation, location flexibility, installation convenience, fruit and vegetable product preservation efficiency, etc. It is an excellent fruit and vegetable storage solution, and has a wide range of application prospects.
