Technical Field

[0001] The invention relates to the technical field of plant beverage concentration, in particular to a concentration device for producing plant beverage. Background Art

[0002] Plant beverages refer to beverage products made from plants or plant extracts through processing or fermentation. Concentration equipment is often used in plant beverages to concentrate them during the production process.

[0003] For example, the patent application document with Chinese invention publication number CN110812914A discloses a plant extract purification and low-temperature concentration device. The device is provided with an extrusion plate, a threaded rod, an adjusting wheel, a filter plate and a filter membrane. The plant extract can be filtered and purified through the filter membrane on the filter plate. During the purification process, the adjusting wheel can be rotated to drive the threaded rod to rotate, so that the extrusion plate on the threaded rod moves downward, and the plant extract can be squeezed, which effectively speeds up the purification efficiency of the plant extract and achieves better use effect. However, the device still has the following problems during use. On the one hand, its concentration efficiency is slow and the concentration effect is not good. On the other hand, solutes are easily accumulated on the surface of the filter membrane, thereby causing blockage of the filter membrane and affecting the filtration process. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned shortcomings in the prior art and to propose a concentration device for producing plant beverages.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: The closure of the bottle is sealed with a sealant on one side of the bottle and is connected to the sealant on the other side of the bottle, the sealant being connected to the sealant on the other side of the bottle.

[0006] Preferably, the vacuum exhaust mechanism comprises a vacuum machine fixedly mounted on the top of the outer tank body, an input end of the vacuum machine is connected to an exhaust pipe, and an end of the exhaust pipe away from the vacuum machine is connected to the interior of the outer tank body.

[0007] Preferably, the telescopic mechanism comprises an electric push rod fixedly mounted at the middle position of the top end of the outer tank body, the telescopic end of the electric push rod is vertically downward and is fixedly connected to the sealing piston after sliding through the top wall of the outer tank body and the top wall of the inner tank body in sequence.

[0008] Preferably, the steam supply mechanism comprises a gas filling pipe connected to the upper end of the rotating connecting pipe, and the end of the gas filling pipe away from the rotating connecting pipe is connected to the external steam supply device after passing through the sealing piston and the side wall of the outer tank body in sequence.

[0009] Preferably, the plurality of magnetic tubes and the air guide tube together form a flower shape.

[0010] Preferably, a support rod is fixedly installed on the lower end surface of the inner tank body, an ultrasonic vibrator is fixedly installed on the upper end at the middle position of the support rod, a sealing fixing frame is fixedly installed on the outer side of the ultrasonic vibrator, the sealing fixing frame is fixedly connected to the nanofiltration membrane, and the working end of the ultrasonic vibrator faces upward and is connected to a rotation buffer assembly.

[0011] Preferably, the rotary buffer assembly comprises a rotary connector fixedly connected to the working end of the ultrasonic vibrator, the upper end of the rotary connector is fixedly connected to a spring, and the top end of the spring is fixedly connected to the lower ends of the plurality of magnetic tubes.

[0012] Preferably, fixing frames are fixedly connected to the four sides of the lower side of the inner tank body, and the lower ends of the fixing frames are fixedly connected to the inner bottom wall of the outer tank body.

[0013] Preferably, a rotating door is installed on the side wall of the outer tank body, and a sealing door is rotatably installed on the side wall of the inner tank body, and the positions of the sealing door and the rotating door correspond to each other.

[0014] Preferably, a water collecting frame placed on the inner bottom wall of the outer tank body is provided below the inner tank body, and the water collecting frame is used to collect water separated from the nanofiltration membrane.

[0015] Compared with the prior art, the advantages of the present invention are: 1. In this application, the vacuum machine is set up so that the boiling point of water will be lowered under low pressure. In the process of concentration using nanofiltration membrane, the liquid can be evaporated and concentrated at a lower temperature, which effectively reduces the risk of these heat-sensitive components being destroyed or inactivated due to high temperature, and helps to better preserve the nutrients and flavor of plant beverages. At the same time, the high-temperature steam can be located above the plant beverage through the setting of the gas pipe, which can provide continuous heat for the concentration process. The heat of the steam can be quickly transferred to the plant beverage to evaporate the water therein. Moreover, due to the high temperature of the steam, the heat transfer efficiency is high. Compared with other indirect heating methods, the water in the plant beverage can reach the evaporation temperature faster.

[0016] 2. In this application, the electromagnetic plates, air guide tubes and magnetic tubes are arranged so that the electromagnetic plates surrounding the inner tank body can generate a magnetic field. Under the action of the magnetic field, the magnetic moment of the water molecules will change its orientation, making the movement of the water molecules more active, easier to overcome the resistance on the surface of the nanofiltration membrane, and more smoothly passing through the nanofiltration membrane. The presence of the magnetic field will interfere with the aggregation process of certain components, affect their migration trajectory, make it difficult for them to deposit on the membrane surface, and improve the service life of the nanofiltration membrane. At the same time, the magnetic field can make the flower-shaped magnetic tubes rotate, and the net-like spherical distribution of the magnetic tubes can have a good stirring effect on the plant beverage and improve the concentration efficiency of the plant beverage.

[0017] 3. In the present application, by setting springs and ultrasonic vibrators, on the one hand, the cavitation bubbles generated when the ultrasonic vibrator is working will produce local strong shock waves at the moment of collapse. These physical effects can prevent the solute from depositing on the surface of the nanofiltration membrane. On the other hand, the magnetic tube connected to the ultrasonic vibrator through the spring will move with the vibration of the ultrasonic wave. This stirring effect can further enhance the anti-clogging effect of the nanofiltration membrane, and the magnetic tube can make the fluid of the plant beverage near the nanofiltration membrane in a good flow state, reducing the concentration polarization phenomenon of the solute on the membrane surface.

[0018] In summary, through the setting of the above-mentioned structure in the present application, on the one hand, the concentration efficiency of the plant beverage can be improved while better retaining the nutritional components and flavor of the plant beverage; on the other hand, the deposition of solutes on the surface of the nanofiltration membrane can be avoided and the anti-clogging effect of the nanofiltration membrane can be enhanced.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figures 1 to 6 A concentration device for producing plant beverages comprises an outer tank body 1, a rotating door is installed on the side wall of the outer tank body 1, a vacuum machine 2 is fixedly installed on one side of the top of the outer tank body 1, an input end of the vacuum machine 2 is connected with an exhaust pipe 3, and the end of the exhaust pipe 3 away from the vacuum machine 2 is connected with the inside of the outer tank body 1, an electric push rod 4 is fixedly installed at the middle position of the top of the outer tank body 1, an inner tank body 8 is arranged inside the outer tank body 1, and a fixing frame 10 is fixedly connected to the lower four sides of the inner tank body 8, and the lower end of the fixing frame 10 is fixedly connected to the inner bottom wall of the outer tank body 1, and the inner tank body 8 is supported by the setting of the fixing frame 10 so that a certain distance is left between it and the inner bottom wall of the outer tank body 1.

[0028] A liquid adding pipe 6 connected to the interior of the inner tank body 8 is fixedly installed on one side of the inner tank body 8, and the end of the liquid adding pipe 6 away from the inner tank body 8 is connected to the liquid adding device after penetrating the side wall of the outer tank body 1. An exhaust pipe 7 connected to the interior of the inner tank body 8 is fixedly installed on the other side of the inner tank body 8, and the end of the exhaust pipe 7 away from the inner tank body 8 is connected to the external environment after penetrating the side wall of the outer tank body 1. A sealing door 9 is rotatably installed on the side wall of the inner tank body 8, and the position of the sealing door 9 corresponds to that of the rotating door, so that the sealing door 9 can be opened together with the rotating door.

[0029] The telescopic end of the electric push rod 4 is vertically downward and is fixedly connected to a sealing piston 12 after sliding through the top wall of the outer tank body 1 and the top wall of the inner tank body 8 in sequence. The sealing piston 12 is sealingly and slidably connected to the inner wall of the inner tank body 8. A rotating connecting pipe 13 is fixedly installed on the lower end of the sealing piston 12. A gas filling pipe 5 connected to the interior thereof is fixedly installed on the upper end of the rotating connecting pipe 13. One end of the gas filling pipe 5 away from the rotating connecting pipe 13 is connected to an external steam supply device after passing through the sealing piston 12 and the side wall of the outer tank body 1 in sequence. An air guide pipe 14 connected to the interior thereof is rotatably installed on the lower end of the rotating connecting pipe 13. A plurality of magnetic tubes 15 connected to the interior thereof are fixedly installed at the lower end of the air guide pipe 14 at equal angles. The plurality of magnetic tubes 15 and the air guide pipe 14 together form a flower shape.

[0030] The high-temperature steam generated by the external steam supply device passes through the gas adding pipe 5, the rotating connecting pipe 13 and the gas guide pipe 14 in sequence and is finally ejected from the multiple magnetic tubes 15, which can provide continuous heat for the plant beverage in the concentration process.

[0031] The lower ends of the plurality of magnetic tubes 15 are fixedly connected to a spring 16, a nanofiltration membrane 20 (a functional semipermeable membrane that allows solvent molecules or certain low molecular weight solutes or low-valent ions to pass through) is detachably installed at the lower part of the inner tank 8, a support rod is fixedly installed on the lower end surface of the inner tank 8, an ultrasonic vibrator 18 is fixedly installed at the upper end of the middle position of the support rod, the ultrasonic vibrator 18 is a prior art, and its specific structural design is not repeated here, a sealing fixing frame 19 is fixedly installed on the outer side of the ultrasonic vibrator 18, the sealing fixing frame 19 is fixedly connected to the nanofiltration membrane 20, the working end of the ultrasonic vibrator 18 faces upward and is fixedly connected to a rotating connector 17, and the upper end of the rotating connector 17 is rotatably connected to the lower end of the spring 16. When the ultrasonic vibrator 18 is running, the magnetic tube 15 connected to the ultrasonic vibrator 18 will move with the vibration of the ultrasonic wave, and this stirring effect can further enhance the effect of preventing the nanofiltration membrane 20 from being blocked.

[0032] A plurality of electromagnetic plates 11 are fixedly installed at equal angles on the side wall of the inner tank body 8. The magnetic properties of two adjacent electromagnetic plates 11 are different. By energizing the electromagnetic plates 11, a magnetic field can be generated between the plurality of electromagnetic plates 11. The generated magnetic field can affect the movement state of water molecules and solute molecules in the plant beverage. A water collecting frame 21 placed on the inner bottom wall of the outer tank body 1 is provided below the inner tank body 8. The water collecting frame 21 is used to collect water separated from the nanofiltration membrane 20.

[0033] The specific working principle of the present invention is as follows: add the plant beverage to be concentrated into the inner tank body 8 through the liquid adding pipe 6, turn on the vacuum machine 2, reduce the air pressure in the outer tank body 1 through the air extraction pipe 3, thereby reducing the evaporation temperature of the water in the plant beverage, energize the electromagnetic plate 11, start the ultrasonic vibrator 18 fixed inside the sealing fixing frame 19, add high-temperature steam into the air guide pipe 14 through the air adding pipe 5, start the electric push rod 4, push the sealing piston 12 to cooperate with the spring 16 at the bottom, and perform regular up and down movements in the inner tank body 8. Such a design has the following advantages: First, under low pressure, the boiling point of water will be lowered. During the concentration process using the nanofiltration membrane 20, the liquid can be evaporated and concentrated at a lower temperature, which effectively reduces the risk of these heat-sensitive components being destroyed or inactivated due to high temperature, and helps to better preserve the nutrients and flavor of the plant beverage. Second: The high-temperature steam is located above the plant beverage, which can provide continuous heat for the concentration process. The heat of the steam can be quickly transferred to the plant beverage to evaporate the water in it. Due to the high temperature of the steam, the heat transfer efficiency is high. Compared with other indirect heating methods, it can make the water in the plant beverage reach the evaporation temperature faster; Third: the sealing piston 12 regularly descends to squeeze the space, which will exert additional pressure on the plant beverage. This pressure helps to squeeze the water in the plant beverage toward the nanofiltration membrane 20. The nanofiltration membrane 20 can selectively allow water molecules to pass through while intercepting the solute components in the beverage. Under the action of pressure, the power of water molecules passing through the nanofiltration membrane 20 is enhanced, thereby improving the concentration efficiency; Fourth: The magnetic field generated by the electromagnetic plate 11 can affect the movement state of water molecules and solute molecules in the plant beverage. Water molecules are polar molecules. Under the action of the magnetic field, their magnetic moments will change their orientation, making the movement of water molecules more active, making it easier to overcome the resistance on the surface of the nanofiltration membrane 20 and pass through the nanofiltration membrane 20 more smoothly; Fifth: The presence of a magnetic field will interfere with the aggregation process of certain components. For example, for some charged ions, the magnetic field may affect their migration trajectory, making it difficult for them to deposit on the membrane surface, thereby increasing the service life of the nanofiltration membrane 20; Sixth: The magnetic field generated by the electromagnetic plate 11 surrounding the inner tank body 8, in conjunction with the rotating connecting tube 13 at the top and the rotating connecting piece 17 at the bottom, can allow the flower-shaped magnetic tubes 15 to rotate. The net-shaped spherical distribution of the magnetic tubes 15 can have a good stirring effect on the plant beverage, thereby improving the concentration efficiency of the plant beverage. Seventh: The flower-shaped distribution and rotation of the magnetic tube 15 can make the ejected hot steam more evenly distributed on the top of the plant beverage, and increase the contact area between the magnetic tube 15 and the inside of the plant beverage, increase heat conduction, make the plant beverage more evenly heated, and improve the concentration efficiency; Eighth: The ultrasonic vibrator 18 will produce cavitation effect when working. In the plant beverage, the cavitation bubble will produce a local strong shock wave at the moment of collapse. These physical effects can prevent the solute from being deposited on the surface of the nanofiltration membrane 20; Ninth: The magnetic tube 15 connected to the ultrasonic vibrator 18 through the spring 16 will move with the vibration of the ultrasonic wave. This stirring effect can further enhance the effect of preventing the nanofiltration membrane 20 from being blocked. The magnetic tube 15 can keep the fluid of the plant beverage near the nanofiltration membrane 20 in a good flow state and reduce the concentration polarization phenomenon of the solute on the membrane surface.

[0034] A pressure valve is provided in the exhaust pipe 7. After a certain pressure is reached and the temperature is transmitted, the hot steam can be discharged through the exhaust pipe 7. Part of the water filtered out by the nanofiltration membrane 20 will drip into the water collecting frame 21, and some gaseous water will be directly sucked away by the vacuum machine 2.

[0035] After the concentration is completed, the sealed door 9 in the inner tank body 8 is opened, and the concentrated plant beverage inside is taken out, and the work is completed.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
