Coffee Bag's four types of packaging

source:other news release time:2023-02-23 Hits:

　　1. Flexible non -gas packaging: This is the most economical packaging. It is usually adopted by local small baking plants because they can guarantee rapid supply. Coffee beans can be consumed in time. Coffee beans under this packaging method can only be stored in a short time.

　　2. Qi -density packaging: After the coffee is packed, it is vacant and sealed. Due to the formation of carbon dioxide during the baking process, this packaging can only be packed after coffee placed for a period of time, so a few days of storage interval. Coffee beans are placed longer than coffee powder. Because it does not need to be separated from air during storage, the cost is low. The coffee under this packaging method should be used up within 10 weeks.

　　3. Unidirectional exhaust valve packaging: Coffee is placed in a special -directional exhaust valve after roasting. This exhaust valve allows gas to go out, but cannot come in. There is no need to store the storage phase, but due to the air deflation process, the aroma will have a little loss. It avoids the formation of corruption, but it cannot prevent the loss of aroma.

　　4. Press packaging: This is the most expensive way, but it can save coffee for two years. After a few minutes of roasting, coffee can be packaged by vacuum. After adding some inert gas, keep the packaging in the package. Coffee beans are kept under pressure to make the aroma flow on fat, which improves the aroma of the beverage.
