Description

Technical Field

[0001] The invention relates to plant extraction technology, in particular to a solvent circulation extraction cup. Background Art

[0002] Existing coffee makers, tea brewers, and health-preserving kettles all require a relatively long heating process. The active ingredients in different food ingredients have different sensitivities to heating. Some heat-sensitive ingredients undergo isomerization after a long heating time. After the heat-sensitive ingredients undergo isomerization, their taste, flavor, and health benefits will be reduced. Summary of the invention

[0003] In view of the above-mentioned defects, the present invention proposes a method for preventing heat-sensitive components in food materials from being isomerized during the heating process, and proposes a solvent circulation extraction cup based on a percolation extraction process, which is convenient for use at home, in the office and during travel.

[0004] Technical solution for realizing the present invention

[0005] A solvent circulation extraction cup, comprising a cup cover, a control circuit board, a pump, an extract container, and a cup body;

[0006] The cup cover comprises an upper shell and a lower shell of the cup cover, the upper shell and the lower shell of the cup cover are sealed and fixedly assembled to form a hollow cavity, and the control circuit board and the pump are installed in the cavity of the cup cover;

[0007] The cup cover lower shell comprises an extension ring along the lower end of the cup cover lower shell, a liquid inlet hole of the cup cover lower shell, a liquid discharge hole of the cup cover lower shell, a sensor through hole of the cup cover lower shell, and a buckle on the inner side of the extension ring wall along the lower end of the cup cover lower shell;

[0008] The liquid inlet hole of the cup cover lower shell is located at the outer side of the extension ring along the lower end of the cup cover lower shell, the liquid discharge hole of the cup cover lower shell is located at the inner side of the extension ring along the lower end of the cup cover lower shell, the sensor through hole is located at the outer side of the extension ring along the lower end of the cup cover lower shell, and the temperature sensor penetrates into the cup body through this hole. A detachable locking buckle is provided on the inner side of the extension ring wall at the lower end of the cup cover lower shell, and a detachable mechanical seal assembly is formed with the extract container through the buckle;

[0009] The control circuit board is used to control the operation of the solvent circulation extraction cup, and includes a microprocessor, a direction sensor, and a temperature sensor, which constitute a control unit;

[0010] Among them, the microprocessor calculates the best extraction time and extraction intensity, that is, the working time and flow rate of the pump, according to different types of extracts and the solvent temperature information detected by the temperature sensor, so as to achieve the best solute dissolution. The microprocessor instructs the pump to start, stop and control the flow rate according to the position signal obtained from the direction sensor. The direction sensor is used to identify whether the cup cover of the solvent circulation extraction cup is in the upper position or the cup cover is in the lower position (i.e., inverted position). The temperature sensor is used to obtain the solvent temperature information in the cup body;

[0011] The pump is used to suck the solvent in the cup body from the liquid inlet hole of the lower shell of the cup cover, and inject the solvent into the extraction container from the liquid discharge hole of the lower shell of the cup cover. The pump is selected from one of a peristaltic pump, a diaphragm pump, an electromagnetic pump, a piston pump, a gear pump, and a centrifugal pump;

[0012] The pump comprises a pump body, a pump inlet pipe, a pump discharge pipe, and a pump fixing bracket, wherein the pump inlet pipe is fixedly expanded and fixed to the inlet hole of the lower shell of the cup cover to form a passage from the solvent in the cup body to the pump body, the pump discharge pipe is fixedly expanded and fixed to the discharge hole of the lower shell of the cup cover to form a passage from the pump body to the extract container, and the pump is fixed to the lower shell of the cup cover by the fixing bracket;

[0014] The extraction container comprises an annular barrel wall, a solid filter screen, a sealing ring, and a convex edge at the upper end of the container. The solid filter screen is placed below the annular barrel wall to form an annular barrel. The convex edge at the upper end of the container is inserted into the buckle inside the extended ring wall along the lower end of the cup cover lower shell to form a detachable locking structure. When the extraction container is locked to the buckle inside the extended ring wall along the lower end of the cup cover lower shell, a sealing assembly is formed by the sealing ring of the side wall of the extraction container and the extended ring along the lower end of the cup cover lower shell to form an extraction working chamber formed by the extended ring along the lower end of the cup cover lower shell and the extraction container. The solvent in the cup body is driven by a pump through the liquid inlet hole of the cup cover lower shell and injected into the extraction container through the liquid discharge hole of the cup cover lower shell, and is discharged into the cup body through the solid filter screen on the extraction container;

[0015] The cup body is a container for holding the solvent, and the upper opening end of the cup body and the side wall of the lower shell of the cup cover form a mechanical seal assembly;

[0016] Working principle of a solvent circulation extraction cup

[0017] During operation, the extract is placed in the extraction container, the extraction container and the lower end of the cup cover lower shell are buckled and locked along the inner side of the extended ring wall, a solvent (drinking water) is added to the cup body, and the solvent circulation extraction cup is inverted. At this time, the direction sensor recognizes that the cup cover of the solvent circulation extraction cup is in the down position (i.e., inverted position). When the cup is in the inverted position, the microprocessor instructs the pump to start, and the pump inlet pipe sucks the solvent (drinking water) and sends it to the extraction container through the pump discharge pipe. The solvent forms a mass transfer reaction with the coffee, tea, and medicinal and edible food in the extraction container. The mass transfer reaction causes the solute to dissolve in the solvent, and the solute-containing solvent permeates through the solid filter. The solvent is sucked into the cup container again by the pump inlet pipe and sent to the extraction container through the pump discharge pipe. This cycle allows the coffee, tea, and medicinal and edible food in the extraction container to undergo a full mass transfer reaction, allowing the solute to be fully dissolved in the solvent. When the mesh density of the solid filter on the extraction container is constant, controlling the flow of the pump can form a certain pressure in the extraction container. The dissolution of the solute under different pressures has certain differences. The microprocessor controls the flow of the pump to achieve the best dissolution effect of the solute. When the extraction time preset by the microprocessor is reached, a prompt sound is issued, the cup is restored to the normal position, and the extraction is completed.

[0018] Positive effects of a solvent circulation extraction cup of the present invention

[0019] The present invention utilizes the percolation method to extract active ingredients in coffee, tea leaves, and edible and medicinal food ingredients, and can realize rapid extraction of active ingredients in coffee, tea leaves, and edible and medicinal food ingredients under normal temperature conditions. Percolation belongs to a dynamic leaching method, and does not require heating, and can avoid isomerization of active ingredients in coffee, tea leaves, and edible and medicinal food ingredients. It has high bioavailability and relatively sufficient leaching of effective ingredients. The percolation method is to place coffee, tea leaves, and edible and medicinal food ingredients in an extraction container, and a solvent forms fluid shearing and scouring on the surface of the coffee, tea leaves, and edible and medicinal food ingredients. The kinetic mechanism of solvent percolation is a method for extracting solute components, and the operation is simple, the bioavailability is high, and the taste quality of the prepared beverage is stable.
