Cold storage preservation of ingredients is a commonly used method nowadays, which mainly uses low-temperature preservation to reduce the metabolic rate of ingredients and extend the preservation time. But as mechanical refrigeration cools down and the relative humidity of the air in the warehouse gradually decreases. The air is getting drier and drier, resulting in a large amount of food losing water and wilting, and a decrease in quality. In the storage of fruits and vegetables, it is necessary to lower the temperature while maintaining a high relative humidity, which is a prominent challenge in fruit and vegetable refrigeration. With the development of technology, there is now a solution, which is to use fruit and vegetable preservation humidifiers - ultrasonic humidifiers.
Ultrasonic humidifier uses the atomizing plate in the humidifier to vibrate thousands of times per second, turning water into an extremely fine mist (with a diameter of less than 5um). It is blown out by a fan and then transmitted through a pipeline to mix thoroughly with air, achieving the purpose of humidification. When the air humidity reaches a relative balance with the moisture content of the food, the water loss rate of agricultural products will decrease, thereby extending the freshness of the food.
How does an ultrasonic humidifier achieve freshness preservation?
Generally speaking, it is recommended to maintain a humidity of 85-95% RH in the cold storage for fresh fruits and vegetables. If matched with the corresponding ultrasonic humidifier, use a fan to remove the small ones. Water mist is blown into the cold storage to maintain the humidity of the air between 85-95% RH. Ultrasonic humidifier for fresh-keeping cold storage and ripening cold storage: through the intelligent humidification system that controls the amount of spray, spray tiny particles of water mist (1-5 microns) into the air-conditioned cold storage to supplement the moisture in the warehouse, so as to preserve the moisture inside the stored fog to maintain the relative stability of the humidity inside the cold storage, and further optimize the fresh-keeping effect of the cold storage.
Advantages of using ultrasonic humidifier:
1. Accurate humidity control can provide specific humidity for specific goods.
2. Increase relative humidity and suppress water loss.
3. Extend storage time and shelf sales time to reduce waste.
4. Maintain the weight of the goods.
5. Maintaining a fresh appearance increases the value of goods.
6. Appropriate humidity levels ensure that product quality remains unchanged.
