Coffee bean storage method coffee bean processing process coffee bean picking process
1. Raw beans:
The raw coffee beans before stir-frying are only for the convenience of transshipment, without special packaging conditions, depending on the different production areas.
For economic and practical considerations, it is generally packed in 60 kg gunny bags and further processed after arriving at the destination. Of course, there will be some different packaging, such as Jamaica Blue Mountain is packed in 70kg wooden barrels.
2. Cooked beans:
Roasted coffee beans are easy to oxidize with oxygen in the air, making the aroma volatilized, the oil quality deteriorated, and the smell of decay. How to maintain the aroma of coffee and prevent the deterioration caused by external temperature, humidity and light is the main task of coffee bean storage.
In addition, because coffee beans produce a considerable amount of carbon dioxide gas after roasting, and carbon dioxide also reduces the aroma of coffee, the packaging of cooked coffee beans should not only avoid contact with the air, but also try to remove carbon dioxide from coffee beans. At present, the commonly used coffee bean packaging methods are as follows:
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 rotten smell, 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.
3. Coffee powder packaging
Coffee powder is mostly used in families, so we choose small packaging, mainly small bag vacuum packaging and canning, in order to use up coffee powder as soon as possible before the quality of coffee powder is changed, among which small bag packaging is more commonly used, so the method is more economical and practical, and the processing cost is also lower.

The process of making coffee beans how to make coffee beans
Roasting coffee beans is a process in which raw beans are roasted using specific equipment to convert starch into sugars and acids at high temperature. in this process, substances such as cellulose will be carbonized to varying degrees, water and carbon dioxide will evaporate, and the protein will be converted into enzymes, which combine with the rest of the fat to form an oil film on the surface of the coffee, and the coffee bean itself.
