With the Delonghi vacuum-sealed coffee canister, you can keep your coffee beans or ground coffee fresh for longer. Delonghi, the expert in great coffee in the UK, knows that the flavor of coffee deteriorates immediately once you open a fresh pack, as the oils are exposed to air. The one-step sealing process, powered by a battery-operated motor, can create a vacuum seal in just 1 to 2 minutes. This allows beans or ground coffee to be kept fresh for an extended period, making great coffee taste even better. You can also set when the canister should be sealed for added freshness. There are 4 automatic settings: when the lid is closed, every 12 hours, every 24 hours, or every 48 hours. The Delonghi coffee canister has a capacity of 1.2 liters, which holds 500 g of coffee beans or 800 g of ground coffee. This should provide ample space for coffee enthusiasts to store a decent amount of coffee. The inner container is removable, and the device is dishwasher safe, making the use of this storage container a breeze.
