How to keep coffee beans fresh in coffee bean metal pails
To keep the coffee beans fresh, coffee bean metal pails need to be considered and designed from many aspects.
1: Sealing performance
High-quality sealing materials: Coffee bean barrels should use high-quality sealing materials, such as silicone or rubber sealing rings. These materials can fit tightly into the gap between the lid of metal pail and the body of metal pail, effectively preventing air and moisture from entering. For example, silicone sealing rings have good elasticity and aging resistance, and can still maintain a good sealing effect even after multiple openings and closings. In addition, the sealing structure design of the lid of metal pail is also critical, such as a screw-type sealing cover or a lever lock ring lid. which can ensure that it is difficult for outside air and moisture to invade when it is closed.
2: Material selection
Oxygen barrier material: The material of the coffee bean metal pail should have good oxygen barrier properties. For example, tinplate or stainless steel in metal materials have a tight molecular structure and oxygen is difficult to penetrate. Coffee bean barrels made of such materials can effectively reduce the contact between oxygen and coffee beans, preventing coffee beans from losing flavor due to oxidation. For plastic coffee bean barrels, plastics with high barrier properties should be selected, and the thickness of the plastic should also be appropriate to ensure sufficient oxygen barrier capacity.
