Vacuum cooler

The pre cooling effect and preservation methods of vacuum pre cooling equipment: vacuum pre cooling is the pre cooling method of the present international advanced, its basic principle is to reduce the pressure on the environment to be cooled by vacuum device to be cooled in water, boiling down to boiling evaporation, thereby absorbing heat and cool to cold thing in itself.

真空預冷可以快速均勻地除去採收帶來的田間熱，降低了食用菌的呼吸作用，從而顯著延長保鮮期，提高保鮮質量。真空預冷屬體積型冷卻方式，整體冷卻速率快，冷卻均勻，受包裝與堆碼方式影響小。特別適用於菌菇、蔬菜、水果、花卉、等的冷鏈保鮮預冷。

The thermal vacuum pre cooling can be quickly removed uniformly recovery, reduce the respiratory function of edible fungus, which can significantly prolong the storage period, improve the preservation quality. Vacuum cooling is a volume type cooling, the cooling rate, uniform cooling, little influence by packaging and stacking method. Especially suitable for mushroom, vegetables, fruits, flowers, and other cold chain storage precooling.

真空冷卻方法與其它冷卻方法相比較，具有如下特點 ：

Compared with other methods of vacuum cooling cooling method, has the following characteristics:

1. 保鮮時間長，無鬚進冷库就可以直接運輸，而且中短途運輸可以不用保溫車；

1 long preservation time, without cold storage can directly transport, but also in the short distance transportation without thermal insulation vehicle;

2. 冷卻時間极快，一般隻需二十幾分鐘，而且凡有齣氣孔的包裝均可；

2 cooling time is very fast, generally only 20 minutes, but all the packaging can hole;

3. 對果蔬原有的感官和品質（色、香、味和營養成分）保持得最好；

3 on fruit and vegetable original sensory and quality (color, aroma, taste and nutrients) to keep the best;

4. 能抑製或殺滅細菌及微生物；

4 can inhibit or kill bacteria and microorganisms;

5. 具有"薄層乾燥效應"—果蔬錶麵的一些小損傷能得到"醫治"癒郃或不會繼續擴大；

5 has "the thin layer drying effect" - the surface of the fruit and vegetable of some small injury can get a "cure" is he not or will continue to expand;

6. 對環境無任何污染；

6 without any pollution to the environment;

7. 運行成本低；

7 low running cost;

8. 可以延長貨架期，經真空預冷的葉菜及食用菌，無鬚冷藏可以直接進高档次的超市。

8 can prolong the shelf life, the vacuum pre cooling of the leafy vegetables and edible fungi, without refrigeration can directly into the high-grade supermarket.

另可適用於預冷新鮮食用菌、鮮切花、生鮮肉、米飯、蒸製品、糕點等。尤其適宜冷卻物品延長貨架期。

The other is suitable for pre cooling fresh mushroom, fresh cut, fresh meat, Steamed Rice, steamed products, cakes etc.. Especially suitable for cooling objects to prolong the shelf life
