The double layer nitrogen oven is mainly composed of a chamber, a heating system, a nitrogen control system, a ventilation system, etc. Before use, the samples need to be placed on a baking tray or grill, and then placed in the oven. The heating system will heat the nitrogen to the required temperature, thereby increasing the temperature in the oven. The ventilation system can exhaust moisture and exhaust gas in the oven to maintain the stability of the environment. The nitrogen control system can control the flow and purity of nitrogen in the oven to ensure that the products are baked or heated in an inert atmosphere.
Nitrogen oven is a kind of equipment that heats and dries under specific environment. Its main feature is that it uses nitrogen as protective gas. It is widely used in industry and scientific research. The following are the specific applications of nitrogen oven in various industrial fields:
1. Food processing field
In the food processing process, nitrogen oven can be used for baking, roasting, drying and other processes, such as baking of biscuits, bread, nuts and other foods, as well as drying of meat, fish and other foods. Nitrogen environment can effectively prevent food from oxidation during baking, so that the food maintains its original color and taste.
2. Electronics industry
In the electronics industry, nitrogen oven is used for drying, sintering, aging and other processes of electronic components. Nitrogen environment can prevent electronic components from oxidation during high temperature treatment and ensure the stable performance of electronic components.
3. Pharmaceutical industry
In the pharmaceutical industry, nitrogen oven is used for drying, sterilization and other processes of medicines. Nitrogen environment can effectively prevent medicines from oxidation, deterioration and other phenomena during high temperature treatment, ensuring the quality and safety of medicines.
4. Material heat treatment
Nitrogen ovens can effectively prevent oxidation reactions during the drying and heat treatment of materials. Many metal and non-metal materials easily react with oxygen under high temperature conditions, resulting in material performance degradation or quality defects. Nitrogen, as an inert gas, does not react chemically with these materials, so it can ensure the stability of the materials at high temperatures. This makes nitrogen ovens widely used in processes such as metal heat treatment and ceramic sintering.
5. Chemical industry
Many chemical reactions and pharmaceutical processes need to be carried out in an oxygen-free environment to prevent oxidation reactions from affecting product quality. The use of nitrogen ovens can provide a stable oxygen-free environment to ensure the smooth progress of the reaction. At the same time, the protection of nitrogen can also extend the storage life of the product and reduce losses during production and storage.
6. Laboratory research
In laboratory research, nitrogen ovens are often used in the heat treatment process of materials. Many materials require a specific atmosphere during the heating process to achieve the desired properties. For example, some ceramic materials need to be sintered in an inert gas environment at high temperatures to avoid volatilization and phase change of components. By filling the oven with nitrogen, the researchers can precisely control experimental conditions to achieve the desired material properties.
The working principle of the double layer nitrogen oven is to create an oxygen-free environment by filling it with nitrogen, thereby ensuring that the baked items will not undergo oxidation reactions at high temperatures.
