How does coffee bean metal pail adapt to coffee beans of different roasting
In order for coffee bean metal pail to adapt to coffee beans of different roasting, they need to be designed and considered from multiple aspects.
1: Adjustment of air permeability
Lightly roasted coffee beans: Lightly roasted coffee beans retain more carbon dioxide. For lightly roasted coffee beans, the coffee bean metal pail needs to have a certain air permeability so that the carbon dioxide can be released slowly. If the carbon dioxide cannot be discharged in time, the pressure in the metal pail will increase, which may cause the coffee bean metal pail to deform and even affect the quality of the coffee beans. For example, coffee bean metal pails with tiny air holes can be used. The size and number of these air holes are carefully designed to allow carbon dioxide to be discharged smoothly without over-oxidizing the coffee beans.
Dark roasted coffee beans: Dark roasted coffee beans release relatively less carbon dioxide, but they are more susceptible to oxidation. For dark roasted coffee beans, the air permeability of the coffee bean metal pail should be appropriately reduced. You can use a coffee bean metal pail with adjustable air permeability. When the coffee beans are just put in, maintain a certain air permeability to allow the residual carbon dioxide to be discharged. After that, you can reduce the entry of oxygen by closing the air holes or using materials with better sealing performance to delay the oxidation process of the coffee beans.
2: Choice of materials
Lightly roasted coffee bean metal pails: As the flavor of lightly roasted coffee beans is more lively, it is easily disturbed by external factors. You can choose materials that have certain barrier properties but are not completely sealed, such as paper coffee bean metal pail with inner membranes. This paper material can prevent the coffee beans from being affected by excessive light and moisture, and the inner membrane can adjust the air permeability to a certain extent.
Darkly roasted coffee bean barrels: The flavor of dark roasted coffee beans is rich and complex, and requires better protection. It is advisable to choose materials with strong sealing properties and good barrier properties to oxygen and moisture, such as metal materials (such as stainless steel, tinplate) or thick-walled plastic coffee bean barrels. These materials can effectively block oxygen, light and moisture, and maintain the flavor and aroma of dark roasted coffee beans.
3: Optimization of internal environment
Humidity control: Coffee beans of different roasting degrees have different requirements for humidity. For all coffee beans, the environment inside the coffee bean metal pail should be kept as dry as possible. Desiccant bags can be placed in the coffee bean metal bucket to absorb excess moisture. The amount of desiccant used and the replacement cycle can be adjusted according to the roasting degree of the coffee beans and the storage environment. For example, in a high humidity environment, the desiccant replacement frequency in the dark roasted coffee bean metal pail may need to be higher, because dark roasted coffee beans are more likely to absorb moisture and deteriorate.
Temperature stability: The coffee bean metal pail should provide a relatively stable temperature environment. Coffee bean metal pail can be made of materials with heat insulation properties, or placed in a storage area with a relatively stable temperature. Whether it is lightly roasted or dark roasted coffee beans, drastic changes in temperature will have an adverse effect on their flavor. For example, avoid placing coffee bean barrels near heat sources or in direct sunlight to ensure that the coffee beans are stored in a suitable temperature range.
