As we all know, most fruits and vegetables have a relatively short fresh-keeping period after being picked from fields and orchards; Therefore, most fruits and vegetables need to be stored at low temperature (below zero) and high humidity. If you want to sell fruits and vegetables at a good price in the market, you need not only to store them for a long time to achieve off-season sales, but also to ensure that the color, smell and taste of fruits and vegetables are almost the same as when they were first harvested. So, fruits and vegetables not only need controlled atmosphere technology to inhibit the respiration of fruits and vegetables, but also to control the relative humidity in the controlled atmosphere warehouse
The fruits and vegetables controlled atmosphere storage is highly praised by many contractors of controlled atmosphere storage, but what we should say here is that if the relative humidity in the controlled atmosphere storage is not well controlled, the gods and horses are floating clouds! In fact, the storage of controlled atmosphere warehouse is to create a specific environment artificially on the basis of cold storage by controlling the temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration in the storage environment; Water retention in fruits and vegetables is the most important factor to maintain their freshness and nutritional quality value; Therefore, the environmental humidity should be kept above 95% RH during the storage and transportation of fruits and vegetables in the controlled atmosphere warehouse to control water loss Status Analysis
It is understood that there are generally three humidification methods for CA storage: steam humidification, watering humidification and ultrasonic humidification
[Watering] Water the ground before sealing the warehouse. This method is very simple. The relative humidity in the reservoir is maintained by evaporation of water. It is true that there will be some effects, but the ground will freeze after using this method for a long time, which will lead to slip and fall when people and vehicles are moving, resulting in safety accidents. In addition, the ground is easy to be damaged if there is water and ice on the ground for a long time, which will affect the service life of the ground
[Steam humidification] Use equipment to generate steam. This method requires a steam source, and then the steam is sent into the warehouse. In addition, the steam sent into the warehouse will cause the temperature fluctuation, so this method is not used in the air-conditioned warehouse at present
[spray humidification] Use special humidification device (non heating mode) to spray tap water after atomization in the warehouse. Adopt_ The humidifier of the controlled atmosphere warehouse for fruits and vegetables and ZS series high humidity resistant spray humidifier are used for scientific and reasonable spray humidification, so as to maintain proper humidity in the warehouse. This is a humidifying method widely used in many controlled atmosphere storages in China Solutions
_ The humidifier for fruit and vegetable controlled atmosphere warehouse and ZS series high humidity resistant spray humidifier products use the principle of ultrasonic high-frequency oscillation to atomize water to 1-5 μ M of ultrafine particles, through the pneumatic device, the water mist is diffused into the air, so as to achieve the purpose of uniform spray humidification; It is used for air humidification, purification, anti-static and dust prevention, cooling, dust reduction and other purposes; It has a very good effect on the fresh-keeping of vegetables and fruits in CA storage. Welcome to consult the humidifier of CA storage for fruits and vegetables and the spray humidifier of CA storage for fruits and vegetables for details
1. Prolong the storage period of fruits, vegetables and meat, which is generally 1-2 times longer than that of ordinary refrigerated warehouses. When they are stored to the most expensive price, they can be sold on the market to obtain the highest profit
2. It can keep the freshness and brittleness of fruits and vegetables. The water, vitamin c content, sugar, acidity, hardness, color and weight of fruits and vegetables after storage can meet the storage requirements
3. The fruit is crisp, and the modified atmosphere storehouse is green, which is almost the same as the newly picked fruit. It can provide high-quality fruits and vegetables to the market
4. It can inhibit the occurrence of diseases and pests of fruits and vegetables, and minimize the weight loss of fruits and vegetables and the loss of diseases and pests
5. The shelving period of fruits and vegetables can be extended to 21 to 28 days, while the shelving period of fruits and vegetables in ordinary refrigerated warehouses can only last for about 7 days before they deteriorate Product application: humidifier for vegetable CA storeroom Product application: humidifier for fruit preservation storeroom Product features_ Compared with humidifiers of other humidification methods, humidifiers of fruit and vegetable controlled atmosphere storage and ZS series high humidity resistant spray humidifiers have significant advantages of [fine atomized particles], [low energy consumption], [high atomization energy efficiency] and [fast humidification speed]. It can not only uniformly humidify a large space, but also locally compensate for humidity in a special space, so it has high flexibility Product application: humidifier for fruit and vegetable CA storeroom Product application: product parameters of humidifier for fruit and vegetable CA storeroom

[Industrial humidifier leasing business] provides flexible leasing solutions to meet customers' short-term and long-term leasing requirements
[Rental charge of industrial humidifier] The price can be determined according to the rental model, rental quantity and rental days To sum up, the air-conditioned warehouse is different from the general cold storage. It is composed of heat preservation, air tightness, refrigeration, air conditioning, humidification, control and other parts. Its cost is higher than that of the general cold storage. The corresponding equipment controls the temperature, humidity, carbon dioxide, oxygen concentration, ethylene concentration and other conditions in the storage environment in the warehouse to inhibit the respiration of fruits and vegetables, so as to achieve the purpose of long-term storage and freshness
Among the existing CA storage fresh-keeping and humidifying devices, there is no humidifying device dedicated to the CA storage, but the humidifying device suitable for ordinary environment is installed in the CA storage to meet the needs of humidifying in the storage. Due to the special environment in the storage, the humidifying device will soon fail. The main reasons are:
1. The CA storage generally requires a high humidity environment above 90% RH, and the electrical components of the humidifying device are easy to rust and damage
2. The storage temperature of some controlled atmosphere warehouses is below zero centigrade, which makes the water supply system of the humidifier frozen and unable to work
3. The storage period of fruit thinning products in the controlled atmosphere warehouse is more than half a year, and the oxygen content in the warehouse is very low. When the humidifier fails, it cannot be repaired
All the above contents about humidifiers for fruit and vegetable controlled atmosphere storage and spray humidifiers for fruit and vegetable controlled atmosphere storage are provided by Mashima Electric Co., Ltd. It mainly introduces the knowledge and methods of humidity control during the use of fruit and vegetable controlled atmosphere storage. Only by properly controlling the temperature and humidity in the controlled atmosphere storage can fruits and vegetables be stored for a longer time, and can also promote vegetables to have a certain freshness_ The humidifier for the air-conditioned fruit and vegetable storage and ZS series high humidity resistant spray humidifier are the best choice for humidification devices in the air-conditioned storage, because they can avoid the phenomenon of water supply pipeline icing when working in a low temperature and high humidity environment, and will not block the pipeline or wetland
