Description

Technical Field

[0001] The utility model relates to the technical field of extraction equipment, in particular to tea polyphenol separation and extraction equipment. Background Art

[0002] Tea polyphenols is a general term for polyphenols in tea leaves. Tea polyphenols have multiple physiological activities such as anti-oxidation, radiation protection, anti-aging, lipid-lowering, blood sugar-lowering, antibacterial and anti-enzyme. Tea polyphenols are separated from tea leaves before extraction. The tea leaves are first crushed, and then the crushed tea leaves are reacted with a solvent to generate an extract, and the crushed tea leaves are subsequently separated from the extract. However, a filtering device is nowadays provided in the extraction equipment, so that when the crushed tea leaves are put into the extraction equipment and stirred with the solvent for reaction, the generated extract is allowed to enter the filtering device, and the extract and the tea leaves are separated by the filtering device. Most of the filtering devices use a filter plate or a filter mesh, and the filter plate is tilted to allow the tea leaves to slide off the filter plate to filter. However, as the use time increases, some tea debris will be clogged in the filter holes of the filter plate, causing problems such as clogging of the filter holes of the filter plate, and since the filter plate is located inside the extraction equipment, it is not convenient for the staff to clean it. Utility Model Content

[0003] The utility model discloses a tea polyphenol separation and extraction device, which solves the problem that after the filter plate in the lifting device is used for too long, some tea debris will be blocked in the filter holes of the filter plate, causing the filter holes to be blocked and inconvenient for staff to clean.

[0004] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions:

[0005] A tea polyphenol separation and extraction device comprises a cylinder, a cover plate is arranged on the top of the cylinder, a No. 1 motor is fixed on the top of the cover plate, a rotating shaft of the No. 1 motor passes through the bottom of the cover plate and is fixed with a stirring rod; a rectangular shell is arranged below the cylinder, a lifting and lowering connecting shell is arranged inside the rectangular shell, a telescopic pipe fitting passing through the rectangular shell and connected to the cylinder is connected to the connecting shell, an electric telescopic rod for driving the connecting shell is arranged on the rectangular shell; a slag discharge pipe fitting passing through the bottom of the rectangular shell and being telescopic is connected to the bottom of the connecting shell, a filter hole is arranged at the bottom of the connecting shell, a plug rod matching the filter hole is fixed at the bottom of the rectangular shell, a cleaning plate movable laterally is arranged inside the connecting shell, a No. 2 motor for driving the cleaning plate is arranged on the connecting shell; a feeding pipe is connected to the bottom of the rectangular shell.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] After the crushed tea leaves and solvent are added into the cylinder, the No. 1 motor can be started to drive the stirring rod to rotate, so as to stir the tea leaves and solvent in the cylinder, so that the tea leaves can fully contact with the solvent and react; when the reaction of the tea leaves and the solvent is completed, the tea residues and the generated extract in the cylinder can be discharged into the connecting shell through the telescopic pipe fitting, and the extract can flow out through the filter holes at the bottom of the connecting shell, and then be discharged through the discharge pipe, while the tea residues are collected in the connecting shell; when the extract is discharged through the discharge pipe, the electric telescopic rod is first started to drive the connecting shell to move downward, stretch the telescopic pipe fitting, insert the plug rod into the filter hole, and The top end of the plug rod is made flush with the bottom surface of the connecting shell, so that the tea leaves blocked in the filter hole are pushed into the connecting shell to dredge the filter hole; then the No. 2 motor can be started to drive the cleaning plate to move, so that the cleaning plate moves horizontally, and the tea residues in the connecting shell are pushed into the residue discharge pipe fitting, so that the tea residues are discharged through the residue discharge pipe fitting, and the cleaning of the tea residues in the connecting shell is completed; the utility model can effectively separate the extract generated by tea leaves and solvent from the tea residues, and effectively clean the tea residues, avoiding the tea residues from being blocked in the filter hole, and no manual cleaning is required by the staff, thereby improving the separation efficiency of the tea residues and the extract.
