Vacuum drying principle of vacuum drying oven

Many customers in the vacuum drying ovens produced by Nanjing Kerry Drying Equipment Co., Ltd. found that the drying effect was not ideal after buying them. Therefore, they always thought that the products they bought did not achieve their expected results. In fact, they only had no understanding of the customers. And use vacuum drying equipment only. Below I will discuss with you how to use the device and how it works.

1. Vacuum drying under reduced pressure. The boiling point of water under normal pressure is 100 degrees. If the pressure is reduced, the boiling point of water will be reduced accordingly. Therefore, the vacuum method can effectively reduce the drying temperature, thereby protecting the product from oxidation and high temperature damage to the product.

2, drying principle, if you put a glass of water in the vacuum drying box you will find that the water will freeze. Because the water will produce sublimation heat under low pressure conditions, taking away the heat of the water. Then the water will freeze and the water vapor will be taken away by the vacuum pump.

3, the use of Nanjing Kairui vacuum drying oven, the use of vacuum drying oven can be adjusted by the degree of vacuum, drying temperature, drying time, constant temperature, vacuuming frequency to achieve the use of the effect of the Zui Dahua. In general, the vacuum is first applied, and the heating is started after the vacuum is drawn, and the temperature rises. Always vacuum and heat. Then adjust the working time and the frequency of vacuuming according to the drying effect.

As long as you understand the above principles and operating methods, you can adjust a series of process operations according to different materials of the user. In this way, the vacuum drying products can be used to reduce energy consumption and meet customer psychological expectations. If you still don't understand, you can always consult Nanjing Kairui Drying Equipment Co., Ltd.
