Description

Technical Field

[0001] This utility model relates to the field of tea extraction technology, specifically a supercritical fluid extraction device for tea enzymatic hydrolysis based on temperature-sensitive control. Background Technology

[0002] Supercritical fluid extraction equipment for tea uses supercritical fluids (such as carbon dioxide) as extractants to extract target components from tea leaves under specific temperature and pressure conditions. This technology achieves selective extraction by adjusting the physical properties of supercritical fluids (such as density and diffusion coefficient), and has advantages such as low temperature and high efficiency, no solvent residue, and complete retention of components. It is widely used in the field of deep processing of tea.

[0003] Existing supercritical fluid extraction devices for tea typically use only the extraction device to directly extract tea leaves without pretreatment, which may increase the extraction time and affect the efficiency of supercritical fluid extraction.

[0004] Therefore, there is a need to provide a supercritical fluid extraction device for tea enzymatic hydrolysis based on temperature-sensitive control. Utility Model Content

[0005] The purpose of this invention is to provide a temperature-sensitive controlled supercritical fluid extraction device for tea enzymatic hydrolysis, in order to solve the problem mentioned in the background art that the existing supercritical fluid extraction devices for tea usually only use an extraction device to directly extract tea leaves, but there is no pretreatment, which may lead to increased extraction time and reduced efficiency of supercritical fluid extraction.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature-sensitive controlled supercritical fluid extraction device for tea enzymatic hydrolysis, comprising a base plate, an mounting base fixedly installed on the top of the base plate, an enzymatic hydrolysis component fixedly installed on the top of the mounting base, a stirring component installed inside the enzymatic hydrolysis component, an extraction component fixedly installed at the other end of the top of the base plate, and a separation and collection component fixedly connected to one end of the extraction component.

[0007] Preferably, a control panel is fixedly mounted on the front of the mounting base, and an enzymatic hydrolysis switch, a dehydration switch, and an extraction switch are sequentially mounted on the surface of the control panel.

[0008] Preferably, the enzymatic hydrolysis component includes a pulverizer, which is fixedly installed on the top of the mounting base.

The reaction vessel is fixedly installed on the base plate, and a butterfly valve is installed at the bottom of the reaction vessel. A discharge port is fixedly connected to the top of the reaction vessel, and a centrifuge is installed directly below the reaction vessel. The structure of the target material is destroyed in advance by the catalytic action of the enzyme, releasing the target components, and then the high permeability of the supercritical fluid is utilized.

[0009] Preferably, the stirring assembly includes an output motor, a controller, and a temperature sensor. The output motor is fixedly installed on the top of the reactor, and a stirring paddle is fixedly installed at the output end of the output motor. The controller is fixedly installed on the outside of the reactor, and the temperature sensor is fixedly installed on the inner wall of the reactor. The stirring generates fluid shear force and turbulence effect through the rotation of the blades, breaking the diffusion boundary layer between the enzyme and the substrate, so that the enzyme molecules diffuse to the surface of the substrate particles more quickly.

[0010] Preferably, the extraction assembly includes a storage tank, a one-way valve is fixedly connected to the top of the storage tank, a connecting pipe is fixedly connected to the bottom of the storage tank, a solenoid valve is installed in the middle of the connecting pipe, a pressure box is fixedly connected to one end of the connecting pipe, a pressure pump is fixedly connected to one end of the pressure box, an extraction vessel is fixedly connected to the other end of the pressure box, an installation block is threadedly connected to the top of the extraction vessel, and a placement rack is fixedly installed at the bottom of the installation block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By pre-treating the tea leaves to be extracted with enzymatic hydrolysis, the target components inside the tea cells are more easily released into the solution. Furthermore, the enzymes can degrade macromolecules that are bound to the target components, reducing the adsorption of impurities during the extraction process and increasing the free rate of the target components.

[0014] Furthermore, by combining enzymatic hydrolysis with supercritical fluid extraction, the enzymatic pretreatment allows the target components to be fully released from the matrix, reducing mass transfer resistance, while the supercritical fluid can rapidly diffuse and dissolve the target components, shortening the extraction time.

The dehydration switch controls the centrifuge 13 to work. The extraction switch can control the solenoid valve 16, the pressure pump 18, and the pressure relief pump 23 to work.

[0023] Furthermore, the enzymatic hydrolysis component includes a pulverizer 4, which is fixedly installed on the top of the mounting base 2. A feed pipe 5 is fixedly connected to the outside of the pulverizer 4, and one end of the feed pipe 5 is fixedly connected to a reaction vessel 6. The reaction vessel 6 is fixedly installed on the base plate 1, and a butterfly valve 12 is installed at the bottom of the reaction vessel 6. A discharge port 11 is fixedly connected to the top of the reaction vessel 6. A centrifuge 13 is installed directly below the reaction vessel 6. The stirring component includes an output motor 7, a controller 9, and a temperature sensor 10. The output motor 7 is fixedly installed on the top of the reaction vessel 6, and a stirring paddle 8 is fixedly installed at the output end of the output motor 7. The controller 9 is fixedly installed on the outside of the reaction vessel 6, and the temperature sensor 10 is fixedly installed on the inner wall of the reaction vessel 6. The tea leaves to be extracted are put into the pulverizer 4 for pulverization. Then, the pulverized tea leaves enter the reaction vessel 6 along the feed pipe 5. Enzymatic hydrolysis solution is added through the discharge port 11. The output motor 7 drives the stirring paddle 8 to stir and mix the tea leaves with the enzyme.

[0024] Furthermore, the extraction assembly includes a storage tank 14, with a one-way valve 27 fixedly connected to the top of the storage tank 14 and a connecting pipe 15 fixedly connected to the bottom of the storage tank 14. A solenoid valve 16 is installed in the middle of the connecting pipe 15, and a pressure boosting box 17 is fixedly connected to one end of the connecting pipe 15. A pressure pump 18 is fixedly connected to one end of the pressure boosting box 17, and an extraction vessel 19 is fixedly connected to the other end of the pressure boosting box 17. A mounting block 20 is threadedly connected to the top of the extraction vessel 19, and a placement rack 21 is fixedly installed at the bottom of the mounting block 20. The separation and collection assembly includes a pressure reducing box 22, with one end of the pressure reducing box 22... The top of the extraction vessel 19 is fixedly connected to the pressure relief pump 23, and the other end of the pressure relief tank 22 is fixedly connected to the separation chamber 24. The top of the separation chamber 24 is fixedly connected to the circulation pipe 26, and one end of the circulation pipe 26 is fixedly connected to the one-way valve 27. A collection container 25 is provided below the separation chamber 24. The enzymatically hydrolyzed tea leaves are placed on the placement rack 21, and then the extraction vessel 19 is threadedly connected to the mounting block 20 so that the tea leaves are placed inside the extraction vessel 19 and the extraction vessel 19 is sealed. Then, the tea leaves are extracted by the fluid in the storage tank 14.

[0025] In this embodiment, the tea leaves are placed in the pulverizer 4, and the enzymatic hydrolysate is added into the reactor 6 through the discharge port 11. Then, the pulverizer 4 and the output motor 7 are started by the enzymatic hydrolysis switch. The pulverized tea leaves then enter the reactor 6 through the feed pipe 5. The output motor 7 drives the stirring paddle 8 to stir and mix the tea leaves with the enzyme. The reactor 6 is lined with heating wires inside its outer shell. After the enzymatic hydrolysis is completed, the heating wires are started by the control panel 3 to heat the inside of the reactor 6 to deactivate the enzyme and prevent it from continuing to act in subsequent extraction. During heating, the internal temperature of the reactor 6 is monitored in real time by the temperature sensor 10. If the temperature is too high or too low, the temperature sensor 10 sends an electrical signal to the controller 9, which then controls the heating wires to adjust the temperature. After heating is completed, the butterfly valve 12 is opened to allow the tea leaves inside the reactor 6 to fall into the centrifuge 13. The centrifuge 13 is started by the dehydration switch to dehydrate the tea leaves. The dehydrated tea leaves are then placed on the rack 21. The extraction vessel 19 is then threadedly connected to the mounting block 20, so that the tea leaves are placed inside the extraction vessel 19 and the extraction vessel 19 is sealed. Then, the extraction switch is activated to start the operation of the solenoid valve 16, the pressurizing pump 18, and the depressurizing pump 23. After the solenoid valve 16 is opened, the fluid inside the storage tank 14 enters the pressurizing box 17 through the connecting pipe 15. The fluid is usually extracted using carbon dioxide gas. The pressurizing pump 18 makes the fluid reach a supercritical state that is neither fluid nor gas under high pressure. Then the fluid enters the interior of the extraction vessel 19, fully contacts the tea leaves, dissolves the target components, and then enters the depressurizing box 22 connected to the top of the extraction vessel 19. The depressurization of the depressurizing pump 23 makes the fluid return to gas. The gas separates from the mixed tea components. The tea components drip down the bottom of the separation chamber 24 into the collection container 25 for extraction. The gas returns to the interior of the storage tank 14 through the circulation pipe 26 and the one-way valve 27 at the top of the separation chamber 24.
