Features:
1.One-way Exhaust Valve The one-way exhaust valve automatically discharges the carbon dioxide produced by the coffee beans in the tank. At the same time, the oxygen and water vapor outside the tank are isolated, so that they cannot enter the tank and cause oxidation of coffee beans.
2.Date Recording Circle Keep track of the canning date or roasting date of the coffee, so you can always know the newness of the coffee beans.
3.Double Reinforced Seal If the coffee beans are not isolated from oxygen after grinding, or if the oxygen barrier technology is not sufficient, the aroma will be lost.
4.Food Grade Stainless Steel Thickened stainless steel tank, strong and durable, anti-corrosion and anti-rust.
