Coffee beans are a must-have drink for many people every morning, but if they are accidentally exposed to moisture, their taste and quality may be affected. In this case, using an oven drying method can help restore the coffee beans to their original state. This article will introduce how to use this method to first aid damp coffee beans.

Preparation

Before we get started, we need to prepare some tools and materials:

• Hygrometer: used to measure ambient humidity.
• Oven: Choose a model that has an adjustable temperature and can maintain a steady temperature.
• Frying pan or baking sheet lined with tin foil: for placing coffee beans.

Use a hygrometer to measure the humidity of your current environment. Ideally, coffee beans should be stored in an environment with a relative humidity of 50-60%. If you find that the humidity of your environment is above this range, please proceed to the next step.

Step 3: Prepare the coffee beans

Pour the damp coffee beans into a pan or baking sheet lined with tin foil, making sure they are evenly distributed on the surface. This allows each coffee bean to be fully exposed to the air and speeds up the drying process.

Set the appropriate time according to the moisture level and quantity of the coffee beans. Normally, 15-20 minutes should be enough for the coffee beans to return to normal. However, if you have a large amount of coffee beans to process, it may take longer.

As the drying process progresses, keep an eye on the beans for any unusual behavior. If you notice that some of the beans are becoming overly burnt or have a burnt smell, stop drying immediately and remove them.

Step 7: Cooling and storage

Once drying is complete, turn off the preheat function and allow the beans to cool gradually with the machine off. Once the beans have cooled completely, store them in a dry, cool, airtight container.
