The difference between vacuum drying oven and ordinary drying oven
The vacuum drying oven ( http://) is an oven that changes the boiling point of water under vacuum and speeds up drying. It is somewhat different from the traditional drying oven. The main difference is the vacuum. Words, in a vacuum environment, there are many effects that cannot be achieved by ordinary environments. This is also the direct reason for many users who choose vacuum drying ovens. Under what conditions, it is impossible to achieve the effect in ordinary drying ovens, but in vacuum ovens. To achieve the effect? 1. When the food is dried, the food material containing a large amount of sugar reacts due to contact with air during the drying process, becomes viscous, and even burns coke, which is under the technical condition of vacuum drying. These changes are well controlled. 2, metal powder or metal products need to be dried at high temperature, at this time using ordinary drying technology, although it can be dried, but it can not prevent the oxidation reaction with oxygen in the air due to high temperature, vacuum oven Nanjing Huaao drying due to air Because of the vacuum pumping, it is not oxidized at any high temperature, and ordinary ovens cannot. 3. Drying of raw materials with characteristics to be recycled, such as materials containing alcohol and ethanol. When drying, use ordinary drying ovens, which is extremely dangerous. Because alcohol and alcohol are flammable gases, they are in contact with Nanjing Huaao dry air. In the high temperature state, it is easy to generate an explosion hazard, and it is not easy to recycle. In the vacuum state, the ethanol which is not easy to contact with the air reduces the risk of explosion, and the vacuum device is a device with very good sealing performance, and can be utilized. Characteristics are recycled. We can observe the use of vacuum drying equipment in some of the above special cases, which are mostly caused by the contact with air. Therefore, we can conclude that the materials that are not easy to contact with air and dry must use vacuum drying oven equipment. Vacuum drying equipment is required for recycling.
