What is the difference between the oven and the blast drying oven? Many people are confused about the difference between the oven and the vacuum drying oven and the blast drying oven when they first accept it.

For the drying of articles, the main methods are direct heating, vacuum and negative pressure dehumidification, or hot air circulation heating. The first type of drying is oven. The most traditional heating method is electric heating. This is a common oven, and it is also a principle that everyone understands. This kind of oven can be better understood by everyone. It is also similar to fire drying. It is mainly used for metals. Food products that do not require much drying speed are most suitable for drying with this type of oven.

The second type of drying is the blast drying oven. The main principle of this type of drying oven is the hot air circulation drying. It has high requirements for drying speed. It mainly aims at the short drying time. The convenience of the hot air circulation drying oven is in place. It can quickly take away the humidity on the articles under the hot air circulation, and make full use of the principle of evaporation. It can dry articles in a short time. The disadvantage is that it is easy to oxidize the surface or damage the surface structure of the object.

The third drying method is vacuum drying oven. This drying method is a kind of uncanny way to dry the goods without any change in the surrounding environment. It is mainly designed for drying heat-sensitive and easily decomposable and oxidizable substances. The design is seamless. Completely avoid changes in the drying process. This drying oven is also the mainstream drying oven for the development of science and technology.
