Description

Technical Field

[0001] The present invention relates to the technical field of vegetable and fruit fermented juice concentration, and in particular to a plant deep processing concentration device. Background Art

[0002] In the production process of vegetable and fruit fermented juice, in order to improve product performance and stability, reduce storage and processing costs, or to develop high value-added products and meet specific finished product form requirements, it is necessary to concentrate the vegetable and fruit fermented juice.

[0003] In Chinese Patent No. 202111111734.3, the invention belongs to the field of carrot juice production technology, specifically to a method and a concentrating device for carrot juice concentration. The method for concentrating carrot juice described in the invention comprises the following steps: subjecting carrot juice to high-pressure membrane concentration to obtain carrot juice concentrate and carrot juice dialysate; the invention uses high-pressure membrane concentration of carrot juice to remove water from the carrot juice, enrich the main nutrients in the carrot juice, improve the purity of the carrot juice product, increase production added value, reduce production costs, and prevent phase change. The impurity content in the obtained carrot juice dialysate is reduced, the transmittance is increased, and it can be directly subjected to biochemical treatment, which is energy-saving and environmentally friendly.

[0004] The composition of fermented fruit and vegetable juice is complex, containing a large amount of macromolecules and colloids such as proteins, polysaccharides, and bacteria. When using membrane reverse osmosis to concentrate it, it is necessary to take into account the activity of the bacteria in the fermented fruit and vegetable juice. It is inconvenient to use a pump with strong shear force to boost pressure or a stirring mechanism to disturb the juice. During the concentration process, small molecules such as water near the membrane surface have been removed through the membrane reverse osmosis, and large molecules remain around the membrane surface, which easily forms a high-concentration boundary layer near the membrane surface and may be deposited to form a gel or filter cake layer, which will affect the permeability of the membrane and thus affect the concentration efficiency.

[0020] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0021] In the prior art, when using membrane reverse osmosis to concentrate fermented fruit and vegetable juice, small molecular components in the juice raw material can be filtered out through the membrane to form a small molecular filtrate, while the remaining large molecular components remain on the other side of the membrane to form a concentrate. The prior art uses hollow tubular membranes to concentrate fermented fruit and vegetable juice raw materials. Under the drive of pressure, the fermented juice reverse osms from the inside of the tubular membrane to the outside, or from the outside to the inside, to complete the concentration. However, the existing tubular membrane is usually set in a static position. During the reverse osmosis process, the small molecular filtrate near the membrane passes through the membrane and is filtered out first, resulting in a higher concentration of large molecules near the membrane. In addition, due to the lack of a mixing mechanism, small molecular components far from the membrane are difficult to approach the membrane, affecting the reverse osmosis concentration efficiency. If the pressure is further increased, it is easy to damage the membrane, affecting its reverse osmosis performance. To solve this problem, the present application makes the following design: Reference Figures 1 to 8 As shown, the present invention provides a technical solution: a plant deep processing and concentration device, comprising a concentration tank 1, a reverse osmosis component 2 is installed inside the concentration tank 1, the reverse osmosis component 2 is arranged in a circular array to form a reverse osmosis cylinder coaxially arranged with the concentration tank 1, and the reverse osmosis cylinder can realize expansion or contraction function, the cross-sectional shape of the reverse osmosis component 2 is set to be V-shaped, and the two side faces of the V are rotatably connected to form an outward longitudinal protrusion, and the respective reverse osmosis components 2 are also rotatably connected to form an inward longitudinal depression, a plurality of guide protrusions 9 are fixedly connected to the inner wall of the concentration tank 1, the guide protrusions 9 correspond one to one to the longitudinal depressions, the guide protrusions 9 are arranged in a circular array with respect to the inner wall of the concentration tank 1, the cross-sectional shape of the guide protrusions 9 is set to be triangular, and the top corners are rounded, and a driving component 3 is also installed inside the concentration tank 1, the driving component 3 is used to carry the reverse osmosis cylinder to realize expansion or contraction function.

[0022] A liquid inlet component 4 is installed on the side of the concentration tank 1. The liquid inlet component 4 is used to add juice raw materials to the interior of the concentration tank 1. A liquid drain component 5 is installed at the bottom of the concentration tank 1. The liquid drain component 5 is used to discharge small molecule filtrate to the outside. After preliminary filtration treatment, the vegetable and fruit fermentation juice raw materials that do not contain solid particles are transported into the interior of the concentration tank 1 through the liquid inlet component 4. It is located in the interlayer cavity between the concentration tank 1 and the reverse osmosis cylinder. At this time, the reverse osmosis cylinder is in a contracted state. The interlayer empty volume between the concentration tank 1 and the reverse osmosis cylinder is large. When the interlayer cavity is filled, the reverse osmosis cylinder is expanded by driving the component 3. When the reverse osmosis cylinder expands outward, the volume of the interlayer cavity between it and the concentration tank 1 is reduced, and the hydraulic pressure of the juice raw materials contained therein increases. At the same time, the internal space of the reverse osmosis cylinder increases, forming a negative pressure. Driven by the high external pressure and the internal negative pressure, small molecular components such as water in the fermentation juice raw materials can pass through. The liquid passes through the reverse osmosis component 2 and enters the reverse osmosis cylinder. After the reverse osmosis cylinder has finished expanding, it contracts inwards under the drive of the driving component 3. During the contraction, the volume of the interlayer cavity increases again, forming a negative pressure. New juice raw materials can enter the interlayer cavity through the liquid inlet component 4 for replenishment. At the same time, the volume inside the reverse osmosis inner cylinder decreases, forming a positive pressure. Under the action of pressure, part of the small molecule filtrate inside is discharged outwards through the drainage component 5, and part of it flows back into the inner part of the interlayer cavity through the reverse osmosis cylinder, forming a backflush, which is convenient for cleaning the reverse osmosis component 2 and preventing it from clogging. This cycle is repeated to retain the concentrated liquid of the vegetable and fruit fermented juice in the interlayer cavity and discharge it outwards after the concentration is completed.

[0023] When the reverse osmosis inner cylinder expands outward, the longitudinal depression is gradually pushed outward under the drive of the driving component 3. In the original state, due to the large distance between the longitudinal depression and the inner wall of the concentration tank 1, a large amount of juice raw materials are accumulated in the longitudinal depression. When it is pushed outward, it can simultaneously push the juice at this position outward, and directionally flush the juice on the surface of the reverse osmosis component 2. This flushing can directly peel off the high-concentration solute layer gradually accumulated on the surface of the reverse osmosis component 2, preventing the high concentration near the reverse osmosis component 2 from affecting its reverse osmosis performance. When the juice flows outward, it encounters the guidance of the guide protrusion 9 at the corresponding position and flows along its inclined surface to both sides, thereby forming a liquid flow disturbance inside the interlayer cavity. While the juice inside the interlayer cavity is pressurized and reverse osmosis concentrated, the liquid flow is disturbed. The liquid flow disturbance can further mix the juice inside the interlayer cavity, preventing high-concentration solutes from continuously accumulating on the surface of the reverse osmosis component 2, facilitating the maintenance of a high reverse osmosis flux and ensuring the concentration efficiency.

[0024] Liquid flow disturbance is achieved through the interaction of the progressive expansion of the reverse osmosis inner cylinder and the directional guidance of the guide protrusion 9, which is a non-contact drive. The liquid flow inside the interlayer cavity is mainly passively generated by the spatial change of the cavity structure. Compared with the traditional method of relying on the rotation of the stirring paddle to achieve turbulent mixing, the present application will not generate a large shear force on the fermented juice while disturbing the mixing, and gradually diffuses along the side of the guide protrusion 9. The flow direction is softer, which can minimize the physical damage to the bacterial flora in the fermented juice.

[0025] Although the traditional plate and frame filter membrane uses the method of allowing juice to flow along the filter membrane to complete reverse osmosis, it can avoid excessive shear force causing damage to its internal bacteria, or a high concentration near the filter membrane, which affects the reverse osmosis flux. However, when the existing plate and frame filter membrane is working, the juice flows in from one side of the membrane and flows unidirectionally along the membrane surface to the other side to complete reverse osmosis. The juice on the side that initially contacts the juice has not yet been concentrated by reverse osmosis and has a low concentration. As the juice gradually flows along the plate and frame membrane, some small molecules have been filtered out, and the juice concentration gradually increases, which puts a greater load on the membrane at the outlet end. There is a difference in reverse osmosis load pressure at the two ends. After long-term use, it is easy to cause uneven wear of the membrane. The end with a greater load pressure is more susceptible to wear. If one end is worn, the entire membrane must be replaced, which will cause certain waste. The upper and lower ends of each reverse osmosis component 2 in the reverse osmosis inner cylinder in the present application are synchronously expanded outward, wherein the entire surface of the reverse osmosis filter membrane 202 synchronously applies uniform pressure to the juice in the interlayer cavity, and the entire reverse osmosis filter membrane 202 synchronously participates in reverse osmosis, and its reverse osmosis load pressure is the same, and the degree of wear at each location is also the same, which is convenient for preventing excessive wear of one end thereof, thereby facilitating extending its service life. Moreover, since the interlayer cavity is an annular structure, when the reverse osmosis inner cylinder expands outward, the juice pressure inside the interlayer cavity is almost perpendicular to the reverse osmosis component 2 for uniform reverse osmosis. Compared with the traditional method of completing reverse osmosis by oblique flow from the membrane surface, the reverse osmosis efficiency of the present application is higher.

[0026] The reverse osmosis component 2 includes an outer support plate 201, the inner wall of the outer support plate 201 is fixedly connected to the inner support plate 203, and a reverse osmosis filter membrane 202 is sandwiched between the outer support plate 201 and the inner support plate 203. The outer support plate 201 and the inner support plate 203 use a mesh plate with diamond-shaped mesh holes to support and fix the reverse osmosis filter membrane 202 to prevent it from deformation or damage.

[0027] The driving assembly 3 includes a driving vertical rod 305, which is inserted into the longitudinal recess of the reverse osmosis cylinder. A servo motor 301 is installed on the top of the concentration tank 1. The output end of the servo motor 301 is fixedly connected to the driving circular plate 302. A driving groove 303 is provided at the bottom of the driving circular plate 302. The driving groove 303 is arranged in a ring array with respect to the bottom of the driving circular plate 302. The shape of the driving groove 303 is set to be arc-shaped. The driving slider 304 is slidably connected inside the driving groove 303. The driving slider 304 is rotatably connected to the top end of the driving vertical rod 305. A limiting circular plate 307 is provided at the bottom of the reverse osmosis cylinder, and the limiting circular plate 307 is fixedly connected to the inside of the concentration tank 1. A limiting slide groove 308 is provided on the top of the limiting circular plate 307. The shape of the limiting slide groove 308 is set to be linear. The inside of the limiting slide groove 308 is slidably connected to the limiting slider 306, and the limiting slider 306 is rotatably connected to the bottom end of the driving vertical rod 305.

[0028] When the output end of the servo motor 301 drives the driving circular plate 302 to rotate counterclockwise, under the guiding effect of the driving groove 303 and the limiting effect of the limiting slide 308, the driving slider 304 gradually slides toward the outer end of the driving groove 303, and at the same time, the limiting slider 306 also gradually slides toward the outer end of the limiting slide 308, thereby driving each driving vertical rod 305 to push outward. While driving the vertical rod 305 outward, since it is inserted into the longitudinal recess of the reverse osmosis cylinder and fixedly connected to the side of the outer support plate 201, it can push the longitudinal recess outward to complete the expansion of the reverse osmosis cylinder. Conversely, when the output end of the servo motor 301 drives the driving circular plate 302 to rotate clockwise, the driving vertical rod 305 will retract the longitudinal recess inward to complete the inward contraction of the reverse osmosis cylinder.

[0029] An upper sealing outer ring 6 and a lower sealing outer ring 7 are provided between the concentration tank 1 and the reverse osmosis cylinder. The upper sealing outer ring 6 is sleeved on the top of the reverse osmosis cylinder, and the upper sealing outer ring 6 is higher than the top of the reverse osmosis membrane 202, and the upper sealing outer ring 6 is lower than the connection between the reverse osmosis component 2 and the driving circular plate 302, which is used to prevent the juice inside the interlayer cavity from flowing out through the gap between the reverse osmosis component 2 and the driving circular plate 302. The lower sealing outer ring 7 is sleeved on the bottom of the reverse osmosis cylinder, and the lower sealing outer ring 7 is lower than the bottom end of the reverse osmosis membrane 202, and the lower sealing outer ring 7 is higher than the connection between the reverse osmosis component 2 and the limiting circular plate 307, which is used to prevent The juice inside the interlayer cavity flows outward through the gap between the reverse osmosis component 2 and the limiting circular plate 307, so as to ensure the sealing of the interlayer cavity. The inside of the reverse osmosis cylinder is fixedly connected with a sealing inner gasket 8. The sealing inner gasket 8 is symmetrically arranged with two upper and lower ones about the horizontal central axis of the reverse osmosis cylinder, wherein the upper sealing inner gasket 8 is flush with the upper sealing outer ring 6, and the lower sealing inner gasket 8 is flush with the lower sealing outer ring 7. The sealing inner gasket 8 is used to ensure the sealing inside the reverse osmosis cylinder. The upper sealing outer ring 6, the lower sealing outer ring 7 and the sealing inner gasket 8 are all designed in a broken line shape, which can be stretched and contracted and can adapt to the expansion and contraction of the reverse osmosis cylinder.

[0030] The liquid inlet assembly 4 includes a liquid inlet pipe 401, the interior of which is fixedly connected to a liquid inlet valve seat 402, a liquid inlet valve ball 403 being embedded on the side of the liquid inlet valve seat 402 close to the concentration tank 1, a liquid inlet spring 404 being fixedly connected to the side of the liquid inlet valve ball 403, and the end of the liquid inlet spring 404 away from the liquid inlet valve ball 403 being fixedly connected to the liquid inlet pipe 401. When the reverse osmosis cylinder contracts, a negative pressure state is formed inside the interlayer cavity. At this time, the replenishing juice can push the liquid inlet valve ball 403, compress the liquid inlet spring 404, and make the liquid inlet valve seat 402 in a smooth state, and then enter the interlayer cavity for replenishment. When the reverse osmosis cylinder expands, the pressure inside the interlayer cavity increases, and under the elastic force of the liquid inlet spring 404, the liquid inlet valve ball 403 is pushed into the through hole of the liquid inlet valve seat 402 to seal it, preventing the juice inside the interlayer cavity from flowing back, so that it can only reverse osmosis inward through the reverse osmosis component 2 under the hydraulic pressure.

[0031] The drain assembly 5 includes a drain port 501, the bottom end of which is fixedly connected to a drain pipe 502. A drain valve seat 503 is fixedly connected to the interior of the drain pipe 502. A drain valve ball 504 is embedded in the bottom of the drain valve seat 503. A drain spring 505 is fixedly connected to the bottom of the drain valve ball 504, and the bottom end of the drain spring 505 is fixedly connected to the interior of the drain pipe 502. When the reverse osmosis cylinder is expanded and its interior is under negative pressure, the drain spring 505 pushes against the drain valve ball 504 and inserts into the drain valve seat 503 to seal it. When the reverse osmosis cylinder is contracted and its interior is under positive pressure, the drain valve ball 504 moves downward under hydraulic pressure, compressing the drain spring 505. At this time, the drain valve seat 503 is in an unobstructed state, and some small molecule filtrate inside the reverse osmosis cylinder can be discharged outward through the drain pipe 502.

[0032] The technical scope of the present invention is not limited to the contents of the above description.
