There are various types of vegetable cold storage, which are mainly selected and designed according to the characteristics and storage requirements of vegetables to ensure the quality and freshness of vegetables. The following are some common types of vegetable cold storage:
Ordinary cold storage: suitable for short-term fresh storage of vegetables.
Air-conditioned cold storage: extends the freshness period of vegetables by controlling the oxygen, carbon dioxide and humidity in the air. This kind of cold storage is especially suitable for vegetables that need to be stored for a long time and are sensitive to the gas environment.
Vacuum cold storage: by reducing the pressure inside the storage, the water on the surface of the vegetables evaporates quickly, thus achieving the effect of preservation. This kind of cold storage is suitable for those vegetables that are easy to rot due to excessive moisture.
Microfrozen cold storage: freezing vegetables to microfrozen state, so that the water inside the vegetable cells freeze, thus slowing down the process of vegetable decay.
Combination of cold storage: the combination of the above cold storage methods to adapt to the preservation needs of different vegetables. This type of cold storage has greater flexibility and adaptability.
In addition to the above several common types of vegetable cold storage, there are cold storage categorized by temperature range, such as high temperature cold storage, medium temperature cold storage, low temperature cold storage and ultra-low temperature cold storage. These cold rooms are designed for different temperatures, and the items suitable for storage also make a difference. For example, high-temperature cold storage is suitable for storing tropical fruits and high-temperature vegetables, such as mangoes, bananas, tomatoes, etc.; medium-temperature cold storage is suitable for storing grapes, apples, cabbages, carrots, etc.; and low-temperature cold storage is more suitable for storing meat, seafood, and other foods.
