PURPOSE:To increase the extraction speed and carry out an effective extraction by providing a partition either one side or both sides of the passage of extracting medium and the passage of extraction feed or reverse extracting medium, each comparted with solid membrane, and increase the light of liquid flow channel. CONSTITUTION:The partitions 30 and 34 having the liquid flow openings 30a and 34a respectively between the solid membrane 3 and the casing 10 in the extracting medium chamber 20, and the partitions 32 and 36 having the liquid flow openings 32a and 36a respectively between the solid membrane 1 and the casing 10, are provided. On the other hand, the partitions 38 and 40 comparting the approach chamber for draining extraction liquid residue 18 into the chambers 14a and 14b, and 18a and 18b respectively are provided on the partitions 12 and 16 and the top and bottom of the casing 10. Because of the partitions of 30-36 and 38-40, the flow passage of the extract and the extracting medium in the casing 10 is formed jetting, and the length of flow passage is extended.
