Vacuum drying ovenBoth the blast drying oven and the blast drying oven are commonly used drying equipment in laboratories. Many people think that there is not much difference between the two, but the equipment used is different according to different drying materials.
1. The principle of drying is different. The blast drying box uses the box body blast circulation to drive the flow of hot air to achieve the purpose of drying. However, after the material is heated, it is easy to produce adverse reactions such as shrinkage and hardening, so heat-sensitive materials should not be dried in a blast drying oven. The vacuum drying box pumps the space where the dry material is located into a negative pressure through a vacuum pump, which is the so-called vacuum state. We know that under vacuum or low pressure, the boiling point of water, solvent and other volatile components in the material is reduced, so that it can be separated from the surface of the material particles at a lower temperature and be pumped away by the vacuum pump. It is mainly used in materials that are oxidized, polymerized and other chemical reactions occur at high temperatures.
2. The scope of application is different. The blast drying oven is widely used in biochemistry, chemical and pharmaceutical, medical and health, agricultural scientific research, environmental protection and other research applications. It is used for powder drying, baking, and disinfection and sterilization of various glass containers. It is especially suitable for heat sensitivity to drying. , Easy to decompose, easy to oxidize substances and complex composition items for fast and efficient drying.
