Tobacco leaf starch extraction device

The utility model discloses a tobacco leaf starch extraction device. The tobacco leaf starch extraction device comprises an extraction pipe, a collection part and a pressurization part. The extraction tube has an inlet, an outlet and a filter portion. The filtering part is arranged at the outlet. The extraction tube is used for containing a tobacco leaf sample and an extraction solution so that the tobacco leaf sample and the extraction solution can react to form an extraction solution. And the collecting part is arranged below the filtering part to receive the extracting solution output from the outlet. The pressurizing part is communicated with the interior of the extraction tube to apply pressure to the interior of the extraction tube, so that the extracting solution flows out through the filtering part under the action of the pressure. Compared with the scheme in the prior art, a beaker does not need to be used for supporting the separating funnel, so that the extraction device is small and exquisite, the
