1.FLexible non-air tight packaging: this is the most economical packaging. It is usually adopted by small local bakeries because they can guarantee quick delivery. Coffee beans can be consumed in time. T he beans in this packaging can only be stored for a short time.
2. Airtight packaging: vacuum and seal the coffee after loading it. Since carbon dioxide is formed during roasting, the packaging can only be packaged after the coffee has been degassed for a period of time, so there are several days between storage. Coffee beans last longer than coffee powder. The cost is low because there is no air separation during storage. This packaging should run out of coffee in 10 weeks.
3. One-way exhaust valve packaging: after baking, coffee is placed in a special one-way exhaust valve with one direction. The exhaust valve allows gas to go out, but not in. Do not needs to store alone stage, but because there is an exhalation process, fragrance can have a little loss. It prevents the formation of putrid odors, but not the loss of aroma.
4. Pressurized packaging: this is the most expensive way to store coffee for two years. Coffee can be vacuumed after a few minutes of roasting. After some inert gas is added, the proper pressure is maintained in the package. The coffee beans are kept under pressure, allowing the aroma to flow through the fat, improving the flavor of the drink.
