Abstract: The disclosure relates to an extraction device for extracting soluble favors from raw materials that are distributed within liquid. The extraction device includes a first container, a second container, a valve, and an air suction device. The second container is configured for storing the mixture of the raw materials and the liquid. The valve is connected to the second container and the first container. The air suction device is connected to the first container and configured to decrease the internal pressure of the first container to a predetermined value. When the internal pressure of the first container reaches the predetermined value, the valve is activated to connect the first container to the second container. The disclosure also relates to an extracting method for using the extraction device.
