What is the effect of vacuum packaging machine?

Why is the vacuum packaging machine so favored? How about the preservation effect of the vacuum packaging machine? What are the main applications of vacuum packaging machines?

Fresh flowers, fruits, vegetables, mushroom and other gardening and vegetable products on the market are easy to deteriorate and rot and lose the value of the products. The vacuum pre-cooling technology and equipment are designed to prevent fresh vegetables, fresh fruits, edible mushrooms and so on. Crops are designed for the decline in freshness and quality during post-harvest refrigerated transport. The basic principle of the vegetable fresh-keeping vacuum machine is to place the post-harvest fruits and vegetables, edible fungi, etc. in a vacuum treatment tank, and the water is evaporated from the surface at a low pressure, and the latent heat of evaporation is obtained by evaporation of water, thereby achieving rapid and uniform treatment. The effect of cooling. Generally, it can be quickly and uniformly reduced to an optimum temperature of about 0 degrees in 30 minutes by vacuum treatment. At the same time, it can effectively maintain freshness, reduce decay, prolong shelf life and shelf life with other comprehensive preservation measures.
The characteristics of vacuum packaging machine pre-cooling and fresh-keeping technology 1. The cooling speed is fast, generally only 20-30 minutes can reach the required refrigeration low temperature, while the ordinary cold storage takes 10-12 hours or even longer.
Therefore, it is possible to eliminate the field heat of vegetables, fruits and flowers in the first time after harvest, which is fatal to preservation.
Second, the cooling is even, the vacuum pre-cooling can quickly cool the special appearance and the core of the fresh-keeping, and reach the required low temperature almost simultaneously from the surface to the inside.
It avoids the external cold internal heat during the traditional refrigeration process, and the central temperature is difficult to be quickly, which leads to the phenomenon that the horticultural products are cohesive and the freshness is decreased.
Third, the surface of fruits and vegetables treated by vacuum preservation can effectively control the humidity, and there will be no slight water loss on the surface during refrigeration.
It also has the unique effect of inhibiting flowering, preventing yellowing of the incision, and inhibiting the curvature of the body.
4. Fresh fruits, vegetables, freshness, color and taste are better, and the vacuum treatment is clean and hygienic, with long storage time and high market selling price.
5. Fruits and vegetables harvested in rainy days or fruits and vegetables washed with water can also be quickly treated, avoiding the internal heat phenomenon of fruits and vegetables, and also removing some surface moisture, which is beneficial to keep fresh.
Sixth, it can be combined with air-conditioning treatment to achieve high difficulty and preservation.
7. It is extremely suitable for the preservation of fresh fruits and vegetables such as fresh leaf vegetables, high-grade vegetables, special vegetables, wild vegetables, edible fungi, high-grade fruits and supermarket clean dishes.
