Description

Technical Field

[0001] This utility model belongs to the field of plant extraction technology, specifically relating to a plant extract extraction device with filtration function. Background Technology

[0002] Plant extracts are chemical substances with specific bioactive components extracted from plants through physical or chemical methods. As a natural, safe, and residue-free green additive, plant extracts are not only rich in nutrients such as vitamins and amino acids, but also contain a variety of bioactive components, such as polysaccharides, flavonoids, phenols, tannins, terpenes, and quinones. They have multiple effects, including antioxidant, antiviral, anticancer, antiparasitic, antifungal, hypoglycemic, antihypertensive, and insecticidal properties, making them an ideal alternative to antibiotics.

[0003] The production of plant extracts involves multiple steps, including crushing, extraction, and filtration. Traditional extraction devices are often limited in function, resulting in insufficient crushing, low extraction efficiency, and poor filtration, making it difficult to meet the needs of modern production. Furthermore, factors such as the amount of solvent added and temperature control during the extraction process also affect the quality and yield of the extract, and traditional devices are not precise enough in controlling these aspects. Utility Model Content

[0004] The purpose of this invention is to provide a plant extract extraction device with a filtration function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plant extract extraction device with a filtration function, comprising an extraction tank, a feeding port, a dust cover, and a discharge chamber. The feeding port is fixedly connected to the top of the extraction tank, and the feeding port is connected to the dust cover via a hinge. The discharge chamber is located at the bottom of the extraction tank and is equipped with a variable frequency speed control motor. The variable frequency speed control motor is fixedly connected to the center of the top of the extraction tank, and a crushing and stirring assembly is fixedly connected to the output end of the variable frequency speed control motor. A filter screen is fixedly connected to the inner wall of the extraction tank, and a condenser tube is fixedly connected to the outer side of the extraction tank. A metering liquid addition assembly is located below the condenser tube. A drainage assembly is fixedly connected to the drain outlet of the extraction tank, and a heating plate is fixedly connected to the bottom of the extraction tank.

[0006] The above-mentioned scheme uses the extraction tank as the core, integrating functions such as feeding, crushing and stirring, filtration, condensation, quantitative liquid addition, heating and discharging. This design realizes the intensive operation of the entire plant extraction process, reduces equipment connection time and material loss, and the variable frequency speed control motor is adapted to the crushing and stirring needs of different raw materials, which can greatly improve efficiency and extract quality.

[0007] In the above scheme, it should be noted that the variable frequency speed control motor, heating plate, temperature sensor and external power supply are electrically connected.

[0008] In a preferred embodiment of a plant extract extraction device with filtration function, the quantitative liquid addition component and the condenser tube are both connected to the extraction tank, and a round hole is provided at the center of the filter screen.

[0009] Using the above scheme, the quantitative liquid addition component can input the extraction solvent into the extraction tank to extract the active ingredients of the plant. The round hole design of the filter screen does not affect the filtration function, and allows the crushing and stirring component to run through the top and bottom, so as to achieve all-round processing of the raw materials.

[0010] In a preferred embodiment of a plant extract extraction device with filtration function, the drainage assembly includes a drain pipe, a circular filter screen, a valve, and a temperature sensor. The circular filter screen is fixedly connected to the inner wall of the drain pipe, and the temperature sensor is fixedly connected to the drain pipe. The valve is fixedly connected to the outer side of the drain pipe.

[0011] Using the above solution, the circular filter screen can prevent solid impurities from clogging the drain pipe and extend the service life of the equipment; the valve enables controllable drainage and facilitates flexible adjustment of the extraction process; the temperature sensor can provide real-time feedback on the temperature status of the extraction system, providing a basis for the adjustment of the heating plate, ensuring that the extraction is carried out at a suitable temperature and guaranteeing the quality of the extract.

[0012] In a preferred embodiment of a plant extract extraction device with filtration function, the pulverizing and stirring assembly includes a first drive shaft, a first ring, a cutting blade, a connecting rod, a second drive shaft, a second ring, and a stirring frame. Multiple first rings are fixedly connected to the outer wall of the first drive shaft, and several annularly distributed cutting blades are fixedly connected to the outer walls of the multiple first rings. One end of the connecting rod is fixedly connected to the bottom end of the first drive shaft, and the other end of the connecting rod is fixedly connected to the second drive shaft. A second ring is fixedly connected to the outer wall of the second drive shaft, and a stirring frame is fixedly connected to the outer wall of the first ring.

[0013] The above-mentioned scheme achieves dual functions of crushing and stirring through a layered design. The cutting blade can crush plant raw materials into fine particles, increasing the contact area with the solvent. The stirring rack can make the extract evenly mixed, accelerating the dissolution of effective components. The linkage structure ensures that crushing and stirring are carried out simultaneously, reducing equipment operating energy consumption and improving extraction efficiency.

[0014] In a preferred embodiment of a plant extract extraction device with filtration function, the drive shaft is fixedly connected to the output end of the variable frequency speed control motor, and the connecting rod is inserted into the round hole of the filter screen.

[0015] Using the above scheme, the variable frequency speed control motor is the power source for the first drive shaft, and the design of the connecting rod passing through the filter screen allows the stirring rack to act on the filtered extract.

[0016] In a preferred embodiment of a plant extract extraction device with filtration function, the quantitative liquid addition component includes an infusion port and an infusion needle tube, wherein the infusion port is slidably connected to the infusion needle tube via an insertion connection.

[0017] Using the above scheme, the sliding plug structure enables quantitative addition of solvent with high precision and simple operation. It can strictly control the ratio of raw materials to solvent and avoid affecting the extraction effect due to too much or too little solvent.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This device, through the coordinated operation of a variable frequency speed-regulating motor and a crushing and stirring component, can flexibly adjust the crushing speed for plant raw materials with different hardness and fiber density. Combined with the ring-shaped distributed cutting blades, it achieves efficient crushing, significantly shortening the raw material pretreatment time. The stirring rack can fully mix the extract, making the raw materials and solvent contact more evenly. Compared with traditional devices, it significantly reduces production energy consumption and time costs, making it suitable for large-scale continuous production.

[0020] The quantitative liquid addition component precisely controls the amount of solvent used, and the temperature sensor monitors and provides feedback on the extraction temperature in real time, avoiding component degradation or incomplete extraction due to parameter fluctuations. A heating device is installed at the bottom of the extraction unit to heat the liquid in the extraction tank, which can accurately adjust the extraction temperature to suit the dissolution characteristics of different plant components. When working in conjunction with the condenser, it can form a good thermal cycle, reducing solvent evaporation loss caused by temperature fluctuations and indirectly reducing production costs.

[0031] The drainage assembly 5 includes a drain pipe 51, a circular filter screen 52, a valve 53, and a temperature sensor 54.

The temperature sensor 54 can provide real-time feedback on the temperature status of the extraction system, providing a basis for the control of the heating plate 6, ensuring that the extraction is carried out at a suitable temperature, and guaranteeing the quality of the extract.

[0033] The crushing and mixing assembly 9 includes a drive shaft 91, a ring 92, a cutting blade 93, a connecting rod 94, a drive shaft 95, a ring 96, and a mixing frame 97.
