| Zusammenfassung: | The utility model discloses a device for extracting maltol from mother liquor. The device comprises a first extraction tower, a second extraction tower, a storage tank, a recycling kettle, a waste liquid tank and a switching unit. A first extraction channel is formed in a manner that the upper end of the first extraction tower is connected with the lower end of the second extraction tower, and a second extraction channel is formed in a manner that the lower end of the first extraction tower is connected with the upper end of the second extraction tower. An extractant in the storage tank enters the bottom of the first extraction tower and enters the second extraction tower through the first extraction channel, and extracted liquor is pumped into the recycling kettle for retreatment after completing extraction; and through switching to the second extraction channel by using the switching unit, the extractant in the storage tank enters the bottom of the second extraction tower and enters the first extraction tow |
