Description

Technical Field

[0001] The invention relates to the technical field of chemistry, in particular to a soybean isoflavone extraction and filtering device and a soybean isoflavone production method. Background Art

[0002] Soy isoflavones are a type of phytoestrogen, also known as plant estrogen, and are a natural hormone. Isoflavones are a type of flavonoid compound, mainly found in leguminous plants, and are a type of secondary metabolite formed during soybean growth. Soy isoflavones are usually extracted using a soybean isoflavone extraction device. When using the existing soybean isoflavone extraction device, it only extracts the defatted soybean meal into the extracting liquid. At the same time, the filter device set in the device also has the risk of being blocked by the soybean meal, resulting in low extraction efficiency and poor extraction effect. Summary of the invention

[0003] The invention aims to overcome the shortcomings of low extraction efficiency, poor effect and poor filtering effect in the prior art when soybean isoflavones are extracted, and provides a soybean isoflavone extraction and filtering device with high extraction efficiency, obvious extraction effect, filter screen not easy to be blocked and good filtering effect, and a soybean isoflavone production method.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A soy isoflavone extraction and filtration device comprises a bracket, a reaction box connected to the bracket, and a filtration device and a lifting device placed in the reaction box, wherein the filtration device is provided with a grinding component and a filtration component, the grinding component is provided with an upper grinding block and a lower grinding block placed below the upper grinding block and matched and connected, the upper surface of the upper grinding block is connected to a rotating motor, the lower part of the upper grinding block is provided with a flushing hole, the bottom of the lower grinding block is fixedly connected to the filtration component, the filtration component is provided with a filter screen, the filter screen is connected to a vibration device, one end of the lifting device is fixedly connected to the bottom of the reaction box, and the other end is connected to the flushing hole.

[0006] The reaction box is fixed at the lower part of the bracket, and a sufficient amount of leaching liquid is placed in the reaction box. The filtering device and the lifting device are placed inside the reaction box, and the lifting device can lift the leaching liquid in the reaction box and inject it into the filtering device. The filtering device is provided with a grinding component and a filtering component. The filtering component is provided with a filter screen. The grinding component is provided with an upper grinding block and a lower grinding block. A gap is left between the upper grinding block and the lower grinding block, and the defatted soybean meal is added between the upper grinding block and the lower grinding block. The upper surface of the upper grinding block is connected with a rotating motor, and the rotating motor drives the upper grinding block to rotate, and the soybean meal is ground again to obtain finer particles, and falls into the filter screen, so that the required components can be better extracted by the extract after being immersed in the extract. A flushing hole is provided on the upper grinding block, and the extract lifted by the lifting device flows out of the flushing hole. The extract flowing out of the flushing hole can clean the soybean meal adhering to the gap between the upper and lower grinding blocks. The extract that has been used to rinse the soybean meal and flows out from the lower grinding block rinses the soybean meal that falls into the filter screen. The rinsing process can also dissolve and extract the soybean isoflavones in the soybean meal. The filter screen is fixed to the lower bottom surface of the lower grinding block. A vibration device is connected to the filter screen. The vibration effect of the vibration device can cause the filter screen to resonate to prevent the soybean meal from clogging the filter screen. At the same time, when the filter screen is immersed in the extract, the vibration effect can accelerate the dissolution and extraction of the soybean isoflavones in the soybean meal by the extract, thereby improving the extraction efficiency and enhancing the extraction effect to a certain extent.

[0007] Preferably, the top surface of the lower grinding block is provided with a circular groove with a rectangular cross section, and the bottom of the circular groove is provided with a conical groove, and the conical groove runs through the bottom surface of the circular groove and the bottom surface of the lower grinding block. The design of the conical groove can make the re-ground soybean meal fall into the filter quickly, thereby improving work efficiency.

[0008] Preferably, the upper grinding block includes a cylindrical block and a conical block, the conical block is placed below the cylindrical block, the cylindrical block is sleeved with the circular groove, the conical block is sleeved with the conical groove, and the outer diameter of the cylindrical block is smaller than the inner diameter of the circular groove. The cylindrical block and the conical block match the circular groove and the conical groove structure shapes respectively, and can be sleeved and installed. The outer diameter of the cylindrical block is smaller than the inner diameter of the circular groove, so that a certain gap is formed after the two are connected, and the gap can be used to add soybean meal, which is convenient for operation.

[0009] Preferably, the inner wall of the conical groove is provided with a grinding layer, the conical surface of the conical block is provided with a grinding layer, and the grinding layer provided in the conical groove matches the grinding layer provided in the conical block. The grinding layer grinds the soybean meal again to make the soybean meal particles finer, and during extraction, the soybean isoflavones in the soybean meal are more easily extracted and dissolved by the extracting liquid, thereby improving the extraction efficiency and enhancing the extraction effect.

[0010] Preferably, the flushing hole is arranged on the conical surface of the conical block, the cross section of the flushing hole is a V-shaped hole opening upward, the flushing hole radially penetrates the conical surface of the conical block, the center of the conical block is provided with a connecting hole, the upper surface of the cylindrical block is provided with an annular liquid guide groove, one end of the connecting hole is connected to the bottom of the liquid guide groove, and the other end is connected to the flushing hole. The flushing hole is designed to be a V-shaped hole opening upward, so that the leaching liquid flowing out of the flushing hole can be flushed out obliquely upward, so that the flushed leaching liquid has a greater impact force, and the soybean meal in the gap between the upper and lower grinding blocks can be fully flushed. At the same time, the flushed leaching liquid also has a greater impact force when flowing to the filter screen, and the soybean meal on the filter screen will be flushed more fully, increasing the dissolution and extraction of soybean isoflavones in the soybean meal by the leaching liquid during flushing, improving the extraction efficiency and enhancing the extraction effect.

[0011] Preferably, the filter screen is arc-shaped, and a connecting bracket is fixedly connected to the center of the upper surface of the filter screen symmetrically, and a clearance hole is arranged on the side of the connecting bracket, and the clearance hole is close to the upper end surface of the connecting bracket, and the upper end surface of the connecting bracket is fixedly connected to the lower bottom surface of the lower grinding block. The arc-shaped filter screen can make the soybean meal scattered by the impact of the leaching liquid gather back to the center of the filter screen, so as to prevent the soybean meal from being dispersed during the flushing and leaching process of the leaching liquid, thereby affecting the leaching efficiency.

[0012] Preferably, the vibration device is fixedly connected to the lower bottom surface of the lower grinding block, and the vibration device includes a vibration motor and a vibration rod, the vibration rod is connected to the vibration motor, and the vibration rod is embedded in the clearance hole. The outer diameter of the vibration rod is smaller than the inner diameter of the clearance hole, the vibration rod is embedded in the clearance hole, the vibration motor drives the vibration rod to vibrate, the vibration rod hits the inner wall of the clearance hole, so that the connecting bracket drives the filter screen to vibrate, when the filter device is immersed in the leaching liquid, the vibration of the filter screen can disperse the soybean meal in the leaching liquid, so that the soybean meal particles fully contact the leaching liquid, improve the extraction efficiency, and enhance the extraction effect. When the filter device is extracted, the vibration of the filter screen can concentrate the soybean meal to the center of the filter screen to prevent the soybean meal from dispersing. At the same time, the vibration effect of the filter screen can prevent the soybean meal from blocking the mesh of the filter screen, affecting the extraction efficiency and extraction effect.

[0013] Preferably, the bottom of the reaction box is connected with an ultrasonic generator, which can increase the extraction rate of soybean isoflavones in soybean meal and improve the extraction efficiency.

[0014] Preferably, a lifting device is provided in the middle of the bracket, the lifting device is fixedly connected to the lower grinding block, and the rotating motor is connected to the upper part of the bracket. The lifting device can be composed of a cylinder and an electric control device, so as to realize the action of immersing the filter device in and out of the leaching liquid according to a certain rule, thereby improving the leaching efficiency and enhancing the leaching effect.

[0016] 1) Making soybean meal: Making soybean meal from soybeans and defatting the soybean meal;

[0017] 2) Extraction, filtration and extraction: Add enough extracting liquid into the reaction box, place the soybean meal between the upper grinding block and the lower grinding block, grind the soybean meal again to obtain finer soybean meal particles, and the ground soybean meal falls into the filter assembly and gathers at the center of the filter. The lifting device repeatedly immerses the filter assembly into the extracting liquid according to a certain rule. After the filter assembly extracts the extracting liquid, the lifting device lifts the extracting liquid into the liquid guide groove. The filter vibrates under the action of the vibration device. When the filter assembly is immersed in the extracting liquid, the vibration of the filter can disperse the soybean meal in the extracting liquid, so that the soybean meal particles are fully in contact with the extracting liquid, improve the efficiency, and enhance the extraction effect. When the filter assembly extracts the extracting liquid, the vibration of the filter can concentrate the soybean meal at the center of the filter to prevent the soybean meal from dispersing. At the same time, the vibration effect of the filter can prevent the soybean meal from blocking the mesh of the filter and affecting the extraction efficiency and extraction effect.
