Introduction to the role of Laboratory nitrogen generators in the coffee industry

　　During the roasting, brewing, and packaging of coffee, nitrogen is often needed to keep it fresh. The Laboratory nitrogen generator is a very economical and convenient nitrogen source. Reducing the time the coffee beans are exposed to oxygen is essential to maintain the taste and freshness of the coffee. If the roasted coffee beans are not properly preserved, a large amount of carbon dioxide will be lost, resulting in a reduction in the unique flavor of the coffee.
　　1. Use Laboratory nitrogen generators in bulk coffee storage
　　Freshly roasted coffee beans can be stored in airtight silos for up to one month if they are not filled. A large amount of nitrogen is needed in the silo to reduce the oxygen content to 3% or less. The equipment can use continuous nitrogen sealing to keep the coffee beans fresh for subsequent filling.
　　2. Nitrogen is used in coffee packaging
　　Generally, a nitrogen source is required during the nitrogen packaging process or the roasted coffee beans use nitrogen to eliminate residual oxygen. The nitrogen in the airtight package can better preserve the coffee by reducing the elimination rate of carbon dioxide, and better preserve the volatile flavors, thereby providing a more stable environment for long-term storage, so that the bulk coffee can be better in long-distance transportation Local freshness also allows canned coffee to extend its shelf life at retailers.
　　3. For coffee capsules and pod coffee machines
　　Separately packed coffee capsules and coffee pods need to be filled with nitrogen to isolate water vapor, light and oxygen. When the capsule is filled with coffee and sealed, nitrogen is injected to achieve the purpose of reducing oxygen. This makes the shelf life of the capsules longer than the shelf life of canned coffee.
　　The nitrogen purity required for packaging varies from 99% to 99.9%, depending on the type of packaging equipment, the number of nitrogen injection ports on the equipment, the amount of nitrogen to be injected in each package and the amount of residual oxygen.
　　4、Nitrogen infused coffee
　　The nitrogen generator is used in the coffee fermentation process. Nitrogen coffee is a mixture of compressed nitrogen or nitrogen and carbon dioxide that is cooled in a small barrel and then served to customers through a halter like beer. The coffee produced by this process has a softer mouthfeel, and the top is covered with dense bubbles, which is better for cold drinks.
