Description

Technical Field

[0001] The utility model relates to the technical field of extraction equipment, in particular to automatic apigenin extraction equipment. Background Art

[0002] Apigenin is a flavonoid compound widely found in plants, including celery, onion, and chamomile. As a natural bioactive substance, apigenin has multiple pharmacological effects, including anti-inflammatory, antioxidant, and anti-cancer properties. Therefore, it has broad application prospects in the fields of food, medicine, and cosmetics. However, due to its low content, its extraction process requires a lot of time and resources. Therefore, how to efficiently and economically extract apigenin from plants has become a major technical issue.

[0003] Traditional apigenin extraction methods mainly include solvent extraction, hot water extraction, and supercritical fluid extraction. Although these methods can obtain a certain amount of apigenin, they have several obvious shortcomings. First, solvent extraction has low efficiency, usually requires a long extraction time, and is prone to thermal degradation of apigenin, affecting its purity and activity. Second, hot water extraction also has the problems of long extraction time and difficult temperature control, which easily destroys the active ingredients of apigenin. Although supercritical fluid extraction has improved the extraction efficiency to a certain extent, the equipment is complex and the cost is high, making it difficult to be widely used in industrial production.

[0004] Based on the above reasons, this application is proposed. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an automated extraction device that can accelerate extraction efficiency and ensure extraction purity.

[0006] The technical solution adopted by the present invention to achieve the above-mentioned purpose is as follows: apigenin automatic extraction equipment, including an extraction tank, an ultrasonic generator, and an ultrasonic vibrating rod, wherein a discharge port is provided at the bottom of the extraction tank, a frame is fixedly connected to the extraction tank near the discharge port, a sealing cover is rotatably connected to the frame, a traction frame is fixedly connected to the sealing cover, an electric telescopic cylinder is rotatably connected to the frame, a piston end of the electric telescopic cylinder is rotatably connected to the traction frame, a turbine fan is rotatably connected to the top surface of the sealing cover, a first motor is fixedly connected to the bottom surface of the sealing cover, and the first motor is dynamically connected to the turbine fan;

[0007] The top of the extraction tank is fixedly connected with an ultrasonic vibration rod, the outer wall of the extraction tank is fixedly connected with the ultrasonic generator, and the ultrasonic generator and the ultrasonic vibration rod are connected through a wire.

[0008] In the above technical solution, a solvent inlet pipe is fixedly connected to the top of the extraction tank, and a flow meter is fixedly connected to the solvent inlet pipe.

[0009] In the above technical solution, a feeding box is fixedly connected to the outer wall of the extraction tank near the top thereof, and a crushing mechanism is provided inside the feeding box.

[0010] In the above technical solution, the crushing mechanism includes crushing rollers, gears and a second motor. Two groups of crushing rollers are rotatably connected inside the feeding box. The roller shafts at one end of the two groups of crushing rollers pass through the feeding box and are fixedly connected to the gears. The two groups of gears are meshed and connected. The second motor is also fixedly connected to the feeding box, and the second motor is powered by one group of the crushing rollers.

[0011] In the above technical solution, a refrigerator and a temperature sensor are fixedly connected to the inner wall of the extraction tank, and a controller is fixedly connected to the outer wall of the extraction tank. The controller is electrically connected to the refrigerator and the temperature sensor.

[0012] Beneficial effects of the utility model:

[0013] 1. After apigenin and solvent are put into the extraction tank, the ultrasonic generator generates high-frequency electrical signals. These high-frequency electrical signals are transmitted to the ultrasonic vibrator through a wire. The ultrasonic vibrator contains piezoelectric ceramics or other converters that can convert high-frequency electrical signals into mechanical vibrations to generate ultrasonic waves. When these ultrasonic waves propagate in the liquid, they produce a cavitation effect, that is, small bubbles form and collapse in the liquid. The collapse of these bubbles will produce strong tiny shock waves, destroying plant cell walls or other solid matrices, promoting the release of solutes, and the solvent can be stirred synchronously by the first motor, thereby increasing the contact area between the celery and the solvent, making it easier for the solute to enter the solvent, and preventing solid particles from settling to the bottom, thereby improving the extraction efficiency.

[0014] 2. Add a crushing mechanism in the feeding box so that when the celery is put into the extraction tank, the raw material can be effectively crushed, increasing the surface area, which helps to improve the extraction rate, and also reduces the initial crushing and transportation work, shortens the operation process, and speeds up production efficiency;

[0015] 3. A refrigerator is installed in the extraction box, and the temperature of the solvent can be detected by a temperature sensor. When the detected temperature is too high, the controller can control the refrigerator to cool the solvent, thereby reducing the degradation of apigenin and other heat-sensitive components, maintaining their activity and stability, and thus improving the quality and purity of the extract.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 —4, apigenin automated extraction equipment, including an extraction tank 100, an ultrasonic generator 200, and an ultrasonic vibrating rod 201. First, a discharge port is provided at the bottom of the extraction tank 100, and a frame 101 is fixedly connected to the extraction tank 100 near the discharge port. A sealing cover 102 is rotatably connected to the frame 101, and a traction frame 103 is fixedly connected to the sealing cover 102. An electric telescopic cylinder 104 is rotatably connected to the frame 101, and the piston end of the electric telescopic cylinder 104 is rotatably connected to the traction frame 103. In this way, the sealing cover 102 can be pulled by the electric telescopic cylinder 104 to move. The sealing cover 102 is rotated to close or open the discharge port, and a turbine fan 105 is rotatably connected to the top surface of the sealing cover 102. A first motor 106 is fixedly connected to the bottom surface of the sealing cover 102. The first motor 106 is power-connected to the turbine fan 105. When there are solvent and raw material (celery) inside the extraction tank 100, the first motor 106 can drive the turbine fan 105 to rotate, thereby stirring the solvent, increasing the contact area between the celery and the solvent, making it easier for the solute to enter the solvent, and preventing solid particles from settling to the bottom, thereby improving the extraction efficiency.

[0023] Furthermore, in order to further improve the extraction efficiency, an ultrasonic vibration rod 201 is fixedly connected to the top of the extraction tank 100, and an ultrasonic generator 200 is fixedly connected to the outer wall of the extraction tank 100. The ultrasonic generator 200 and the ultrasonic vibration rod 201 are connected by a wire, so that high-frequency electrical signals are generated by the ultrasonic generator 200, and these high-frequency electrical signals are transmitted to the ultrasonic vibration rod 201 through the wire. The ultrasonic vibration rod 201 contains piezoelectric ceramics or other conversion devices, which can convert the high-frequency electrical signals into mechanical vibrations to generate ultrasonic waves. When these ultrasonic waves propagate in the liquid, a cavitation effect is generated, that is, small bubbles are formed and collapsed in the liquid. The collapse of these bubbles will generate strong tiny shock waves, which will destroy the plant cell walls or other solid matrices and promote the release of solutes.

[0024] In addition, a solvent inlet pipe 107 is fixedly connected to the top of the extraction tank 100, and a flow meter 108 is fixedly connected to the solvent inlet pipe 107. After the solvent inlet pipe 107 is connected to the solvent supply system, solvent can be automatically added to the extraction tank 100, and the amount of addition is calculated by the flow meter 108, which reduces manpower and improves automation. Of course, a feeding box 109 is fixedly connected to the outer wall of the extraction tank 100 near its top, and raw materials can be added to the extraction tank 100 through the feeding box 109;

[0025] Further optimized, a crushing mechanism is provided inside the feeding box 109, and the crushing mechanism includes a crushing roller 301, a gear 302 and a second motor 303. Two sets of crushing rollers 301 are rotatably connected inside the feeding box, and one end of the roller shaft of the two sets of crushing rollers 301 passes through the feeding box and is fixedly connected to the gear 302. The two sets of gears 302 are meshed and connected. The feeding box is also fixedly connected to the second motor 303, and the second motor 303 is power-connected to one set of crushing rollers 301. When raw materials are added through the feeding box 109, the two sets of crushing rollers 301 can be driven to rotate by the second motor 303 to crush the raw materials. This increases the surface area and helps to improve the extraction rate. Compared with crushing the raw materials first and then putting them into the extraction tank 100, it can also reduce the early crushing and transportation work, reduce the operation process, and speed up production efficiency.

[0026] For further optimization, a refrigerator 401 and a temperature sensor 402 are fixedly connected to the inner wall of the extraction tank 100. Here, the refrigerator 401 can be a semiconductor refrigerator 401, and the temperature sensor 402 can be a DS18B20 sensor. A controller 403 is fixedly connected to the outer wall of the extraction tank 100. The controller 403 is a controller 403 developed based on Arduino Uno. The controller 403 is electrically connected to the refrigerator 401 and the temperature sensor 402. In this way, the temperature of the solvent in the extraction tank 100 can be detected by the temperature sensor 402. When the detected temperature reaches the set value, the controller 403 controls the refrigerator 401 to work, thereby cooling the solvent. This can reduce the degradation of apigenin and other heat-sensitive components, maintain their activity and stability, and thus improve the quality and purity of the extract.
