If you need to store high-grade fruits and vegetables after the cold storage is completed, you should first precool them, such as broccoli, celery, bitter gourd and yam. These vegetables must be precooled. After the cold storage is built, if you need to store vegetables with high heat, first treat them with ice water and put them in ice water until the temperature of the vegetables is effectively reduced to about seven degrees, then take them out and drain them, and finally put them in the cold storage. Vegetables with relatively high calories include corn, green beans, edamame, rattan and so on. In order to effectively reduce the temperature of vegetables, we can also spread ice on the bottom after harvest. After the leafy vegetables are harvested, they should be sprayed with ice water before being put into the cold storage. Treated vegetables can also reduce the evaporation of water.
Other vegetables also need to be cleaned and then put on the ground for ventilation. It is also necessary to sprinkle water on vegetables from time to time, which can effectively cool down. Spray ice water every hour, such as green pepper, onion, garlic, tomato, eggplant, potato, etc. If you don't know much about the methods of keeping vegetables fresh after the cold storage is built, it will definitely affect the quality of fruits and vegetables.
If there is a cut on the vegetable, it is necessary to put the cut down, and at the same time, in the process of preservation, it is necessary to avoid cold air blowing directly on the vegetable, otherwise it may cause the vegetable to lose more water and wither.
