Basic knowledge of Coffee packing of coffee beans
Flexible non-airtight packaging: this is the most economical one. It is usually used by local small baking plants because they can guarantee rapid supply and coffee beans can be consumed in time. Coffee beans in this way can only be preserved for a short time. Usually no more than a week.
Airtight packaging: suitable for bars, shelves or families, mainly in small bags and cans, coffee is vacuum and sealed after being packed. As carbon dioxide is produced after roasting, this method can only be carried out after the coffee has been degassed for a period of time. The storage period of coffee beans should be longer than that of coffee powder. Because the storage period does not need to be separated from the air, so the cost is low. The coffee under this packing should be used up within 10 weeks.
One-way valve packaging: a variety of sealed containers can be used. The roasted coffee is put into a special airtight container with an one-way valve, which can only remove the gas without inflow, ensuring the insulation of the coffee from the outside air and the timely discharge of carbon dioxide. There is no need for separate storage stage, but due to the outgassing process, there will be a certain loss of aroma. This method can avoid the formation of xxx flavor, but can not prevent the loss of aroma.
Pressurized packaging: this is the most expensive way, but it can preserve coffee for up to two years. The size depends on the type of user, family or bar. After a few minutes of baking, the coffee can be packed in a vacuum. After adding some inert gas, the appropriate pressure is maintained in the package, and the coffee beans are preserved under pressure, leaving the aroma on the fat, thus improving the aroma of the beverage.
