Controlled atmosphere cold storage installation is based on the ordinary cold storage to increase the gas composition.
Controlled atmosphere cold storage installation is based on the ordinary cold storage to increase the gas composition regulation, through the storage link temperature, humidity, carbon dioxide, oxygen concentration and vinyl dragon conditions control, inhibit the respiration and self-consumption of fruits and vegetables, so as to maintain the texture of stored food, color, taste and so on for a long time.
Controlled atmosphere cold storage is composed of airtight layer and insulation layer, and the envelope structure is assembled by color plated polyurethane sandwich board to achieve better heat insulation, moisture resistance and air tightness.(Vegetable and fruit atmosphere preservation warehouse) What are the characteristics of stored vegetables and fruits: keep the original shape, color and fragrance of vegetables and fruits well; fruit hardness is higher than ordinary refrigeration; storage time is longer; fruit flooding rate is low, natural loss (water loss rate) is low; prolong shelf life.
The fruits and vegetables stored in the controlled atmosphere cold storage have a longer storage time, generally 0.5 - 2.0 times longer than ordinary cold storage.
Users can flexibly control the delivery time, capture sales opportunities, and create the best economic results.
The fruits and vegetables stored in the conditioned atmosphere warehouse have a process of transformation from a dormant state to a normal state after being stored, so that the shelf life of the fruits and vegetables after being stored in the warehouse can be prolonged by 21 - 28 days, which is 3 - 4 times that of ordinary cold storage.
Controlled atmosphere preservation warehouse is a kind of low oxygen environment, can inhibit the growth of fruit and vegetable mold, pests and diseases, so that the weight loss of fruits and vegetables to a minimum.
For general high temperature cold storage difficult to store fruits and vegetables, such as kiwi fruit, dates, etc.
can achieve excellent storage effect.
CO2 removal equipment; ethylene removal equipment; Gas detection equipment;
Humidifying equipment; Temperature and humidity control equipment; library detection control equipment; Gas conditioning stations; Automatic control platform, etc.
By adding the equipment and the system, the gas components and humidity in the controlled atmosphere preservation warehouse can be automatically adjusted, the respiratory intensity of fruits can be reduced, the decomposition process of nutrients can be delayed, the storage period of fruits can be prolonged without losing the original color, moisture, shape and nutrition, and the shelf life can be prolonged.
Controlled atmosphere storage is a multi-technology, multi-equipment, multi-control integrated refrigeration project, because of its particularity, so the price is different from the general cold storage.
Controlled atmosphere cold storage is a special cold storage facility.
It controls the gas composition in the cold storage, mainly by reducing the oxygen content and appropriately changing the ratio of carbon dioxide and nitrogen to inhibit the respiration in the food, thereby extending the freshness and shelf life of the food.
The operating principle of the controlled atmosphere cold storage is based on the control of oxygen and carbon dioxide.
By reducing the oxygen concentration, it can inhibit the growth of microorganisms and reduce the spoilage process of food.
Carbon dioxide has antibacterial and antioxidant effects, which helps to further slow down the aging and spoilage of food.
At the same time, the temperature and humidity of the controlled atmosphere refrigerator need to be precisely controlled to meet the requirements of different food storage.
In addition, the controlled atmosphere warehouse has special requirements on the building structure.
In order to ensure the stability of the gas composition in the warehouse, the controlled atmosphere warehouse must have strict airtightness to prevent external air from entering.
At the same time, because the controlled atmosphere warehouse is closed, it is also necessary to consider its safety to avoid potential risks caused by internal and external pressure differences during the cooling process.
In terms of applications, controlled atmosphere refrigerators are widely used in fruits and vegetables, meat, seafood and other fields.
With the increasing demand for fresh, high-quality food, CA cold storage provides an effective preservation solution for these products.
At the same time, CA cold storage also plays an important role in agricultural exports and cold chain logistics, improving product quality and market competitiveness.
