The effect of vacuum pre cooling machine for fruits and vegetables on vegetable preservation

　　A vacuum pre cooler for fruits and vegetables is a device that utilizes the principle of fast cooling of fruits and vegetables in a vacuum environment. By vacuuming, the pressure in the environment where the fruits and vegetables are located is reduced, thereby accelerating the evaporation of water inside the fruits and vegetables, taking away the heat of the fruits and vegetables, and achieving rapid cooling. A vacuum pre cooler can quickly lower the temperature of fruits and vegetables to near ambient temperature, thereby slowing down their respiration, delaying their metabolism, inhibiting physiological diseases, and extending their shelf life. So, what are the specific functions of the fruit and vegetable vacuum pre cooler for vegetable preservation? This article will introduce it to everyone. Please continue reading:

　　The natural characteristics of fruits and vegetables

　　When newly harvested vegetables and fruits still have life, they will produce respiration, which will also consume the nutrients of the vegetables and fruits themselves. Vegetables that consume nutrients will easily change color, shrink, rot, and their appearance will also deteriorate. Another reason is due to the way vegetables are processed after harvesting, which makes them easy to pile up together. The accumulation of a large amount of vegetables also generates heat, which can easily cause the vegetables to spoil and rot, making it difficult to sell at a good price.

　　The effect of vacuum pre cooling machine for fruits and vegetables on vegetable preservation

　　1. The vacuum pre cooling machine for fruits and vegetables is used to quickly reduce the temperature of vegetables to control them from producing respiration and enter a dormant state. Taking freshly picked strawberries as an example, they are also easily perishable fruits, so they need to be pre cooled immediately after harvesting to prevent a decrease in their quality. If strawberries are exposed to high temperatures, they will become soft or even rot within four hours. However, if pre cooled immediately after picking, strawberries can be stored for more than ten days or even longer.

　　2. The main function of a fruit and vegetable vacuum pre cooler is to prevent a decrease in the freshness and quality of vegetables. Using the principle of vacuum design, vegetables are placed in a vacuum chamber, and a large amount of water evaporates from the surface of the vegetables under low pressure. The evaporated water is used to extract latent heat of evaporation from the surface of the vegetables, thereby achieving the effect of vegetable cooling. This is the main function of the fruit and vegetable vacuum pre cooler for vegetable preservation.

　　We will briefly introduce the role of fruit and vegetable vacuum pre cooling machine in vegetable preservation here. The function of fruit and vegetable vacuum pre cooling machine is not only to cool down. Correctly speaking, a high-end fruit and vegetable vacuum pre cooler has more than just the ability to quickly cool down. It can also repair vegetable cuts and prevent the effects of rotting vegetable roots and red vegetable roots.
