[0002] Hesperetin is a natural flavonoid compound that is mainly found in the peels of citrus fruits, such as oranges, grapefruits, and lemons. It has strong antioxidant properties, can neutralize free radicals in the body, reduce oxidative damage, and promote cell health. Studies have shown that hesperetin helps reduce inflammation and is helpful in preventing chronic diseases. At the same time, it can also lower blood pressure and improve blood lipid levels, which is beneficial to cardiovascular health. At present, high-purity hesperetin is usually prepared from Citrus aurantium fruits. The preparation process requires multiple extractions with alcohol solvents, and the original solution obtained by extraction needs to be heated and concentrated. Traditional concentration equipment has problems such as small evaporation area and uneven heating, resulting in low purification efficiency and difficulty in recovering the solvent for secondary use. A new type of refining equipment is needed to solve the above problems. Utility Model Content

[0014] The present invention will be further described below with reference to the accompanying drawings:

[0015] like Figure 1 and Figure 2 As shown, the hesperetin concentration and refining device includes a refining box 1, which is divided into an upper and lower layer by a partition 101. A plurality of refining tubes 2 are obliquely arranged in the upper evaporation chamber 102. The upper half of the refining tube 2 in the chamber is provided with a plurality of groups of small holes 201 distributed parallel to the axial direction. The refining tube 2 is wrapped around the tube body of the refining tube 2. The heating ring 3 is arranged between adjacent groups. The bottom of each heating ring 3 is connected by a wiring tube 301. The positive and negative lines of the heating wire in the heating ring 3 are connected to the distribution box 302 on the outer wall of the refining box 1 through the wiring tube 301. The power line of the distribution box 302 is connected to the external power supply. The distribution box 302 can adjust the heating power of each heating ring 3 through the corresponding knob 303.

[0016] In this embodiment, each refining tube 2 distributes the flow through a dosing assembly, which includes a distribution box 4. The bottom surface of the distribution box 4 is a slope 401. The top surface of the distribution box 4 is connected to the feed hopper 5. The bottom outlet of the feed hopper 5 is located above the slope 401. The bottom of the slope 401 is connected to the upper end of each dosing tube 6. The tube body of the dosing tube 6 is provided with a control valve 601. The lower end of the dosing tube 6 is connected to the oblique upper end inlet of the refining tube 2. The oblique lower end outlet of the refining tube 2 passes through the outside of the evaporation chamber 102. A collecting tank 9 is provided below the outlet of the refining tube 2.

[0017] In this embodiment, the evaporation chamber 102 is connected to the lower recovery chamber 104 through a negative pressure component. The negative pressure component includes a transfer box 7. Each input pipe 701 on the top of the transfer box 7 is connected to the exhaust port 103 on the side wall of the evaporation chamber 102. The bottom outlet of the transfer box 7 is connected to the recovery chamber 104 through a negative pressure pump 8. The output pipe 801 of the negative pressure pump 8 is inserted below the liquid level of the recovery chamber 104. The alcohol gas drawn into the chamber is directly dissolved in the alcohol solution. A discharge pipe 105 with a regulating valve is provided at the bottom of the recovery chamber 104. The alcohol solution is discharged from the recovery chamber 104 through the discharge pipe 105 for secondary utilization.

[0018] The working principle of this utility model is as follows:

[0019] A raw solution enriched with hesperetin is injected from the feed hopper 5 into the distribution box 4. The control valves 601 are adjusted to ensure a laminar flow of the raw solution into the refining tube 2 at a specified flow rate. The heating power of the front, middle, and rear heating rings 3 is adjusted using knobs 303 to gradually evaporate the alcohol solvent in the raw solution and allow it to enter the evaporation chamber 102 through the aperture 201, while also preventing overheating of the raw solution. During the concentration process, the negative pressure pump 8 is activated to evacuate the evaporation chamber 102, drawing the alcohol vapor into the recovery chamber 104 for subsurface dissolution. The regulating valve on the discharge pipe 105 is then opened to transfer the alcohol solution for secondary use. After evaporation and alcohol removal, the hesperetin concentrate flows into the collection tank 9 for collection. The collected concentrate can then be reinjected into the feed hopper 5 for secondary refining.

[0020] The utility model adds a raw solution enriched with hesperetin into each refining tube 2 through a dosing assembly. As the raw solution flows downward along the tube body, it is gradually heated by the heating ring 3 to evaporate the alcohol solvent in the solution, thereby significantly increasing the evaporation area of ​​the raw solution and improving the concentration efficiency. The alcohol solvent is drawn into the recovery chamber 104 through the negative pressure assembly for reuse, thereby achieving the characteristics of energy conservation and emission reduction.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
