Description

Technical Field

[0001] The present invention relates to the technical field of liquid filtration, and particularly to a cylindrical filter for the production of plant protein beverages. Background Art

[0002] Plant protein beverages are milky liquids processed mainly from plant kernels, pulp, etc. Generally, they need to go through filtration operations and homogenization operations to ensure that some larger solid particles and fine particles contained in the plant protein beverages can be removed.

[0003] Currently, for the filtration of plant protein beverages, industrial filter papers made of PET and PP materials are used. Such industrial filter papers for liquids can remove fine particles and odors in the raw materials, improving the taste and quality of the products.

[0004] For such industrial filter papers, due to production limitations, the pore size distribution of the filter paper is a relatively random distribution. Thus, in actual filtration, the filtration effects of different parts of the filter paper vary, resulting in the content of fine particles and the odor removal effect of the filtered beverage solution not being as expected. In addition, since plant protein beverages are milky liquids with poor fluidity, when they come into contact with the filter paper in the filtration container, if the surface of the filter paper is occupied by solid particles and fine particles generated during filtration, the subsequent liquid filtration efficiency will be reduced. Summary of the Invention

[0005] The present invention provides a cylindrical filter for the production of plant protein beverages, enabling a part of the filter paper to move cyclically relative to the filtration area within the cylindrical filtration device, allowing the solution to uniformly contact each part of the filter paper, and avoiding the influence of uneven pore size distribution of the filter paper on the content of fine particles and the odor removal effect, thereby solving the problems raised in the above background art, that is:

[0006] The pore size distribution of the filter paper is a relatively random distribution, and in actual filtration, the filtration effects of different parts of the filter paper vary, resulting in the content of fine particles and the odor removal effect of the filtered beverage solution not being as expected.

[0007] To achieve the above object, the present invention provides a cylindrical filter for the production of plant protein beverages, including a feed cylinder and a first flow channel, a second flow channel, and a discharge channel connected in sequence. It further includes a double-layer filtration mechanism, comprising a horizontal filtration component and a vertical filtration component. The horizontal filtration component is arranged in the first flow channel, and the vertical filtration component is arranged at the connection between the second flow channel and the discharge channel;

[0008] The horizontal filtration component and the vertical filtration component each include a moving filter paper;

[0009] The lateral filtering component further includes a driving shaft roller group and a vertical guiding component that can drive the moving filter paper to move and form a wavy filtering cross-section with a middle bulge and concave on both sides.

[0010] The vertical filtering component includes rotating shafts wound around the four corners of the moving filter paper, enabling the moving filter paper to form a movable filtering surface that vertically partitions the second flow channel.

[0011] As a further improvement of this technical solution, the driving shaft roller group includes a main driving motor, winding shaft rollers arranged on both sides of the first flow channel, and a concave guiding shaft roller arranged inside the first flow channel. The moving filter paper passes through the first flow channel, and both ends of the moving filter paper are wound and connected to the two winding shaft rollers respectively, and the part of the moving filter paper inside the first flow channel bypasses the concave guiding shaft roller, so that a movable concave filtering structure is formed on both sides inside the first flow channel.

[0012] As a further improvement of this technical solution, the vertical guiding component includes an auxiliary driving motor and a vertical guiding shaft roller. The vertical guiding shaft roller is arranged in the upper half inside the first flow channel, the auxiliary driving motor is arranged outside the first flow channel and is connected to the vertical guiding shaft roller. The moving filter paper bypasses the vertical guiding shaft roller, so that the vertical guiding shaft roller forms a filtering structure with an upward bulge in the middle of the first flow channel.

[0013] As a further improvement of this technical solution, the second flow channel is a leaky channel that is wider at the top and narrower at the bottom. The vertical filtering component is arranged at the center of the second flow channel, and the bottom end of the vertical filtering component fits against the narrow channel part of the second flow channel.

[0014] As a further improvement of this technical solution, the vertical filtering component further includes a shielding arc top and an internal driving member. The shielding arc top is arranged below the connection between the first flow channel and the second flow channel, and the internal driving member is arranged vertically below the shielding arc top;

[0015] Among them, the rotating shafts wound around the four corners are included in the internal driving member, and the internal driving member further includes an electric driving member. The electric driving member is arranged inside the shielding arc top. The rotating shafts wound around the four corners are arranged at the four corners at the lower end of the shielding arc top, and the electric driving member is connected to one of the shaft bodies of the rotating shafts wound around the four corners. The moving filter paper is wound around the outside of the rotating shafts wound around the four corners, so that the moving filter paper forms a vertically partitioned filtering surface at the center inside the second flow channel.

[0016] In this technical solution, the moving filter paper inside the first flow channel and the second flow channel is in a moving state during filtration. This moving state can prevent the plant protein beverage with poor fluidity from being affected by the uneven pore sizes of the moving filter paper during filtration, and at the same time increase the fluidity of the plant protein beverage at the contact position with the moving filter paper, improving the filtration effect. In addition, in the first flow channel, horizontal filtration is carried out through the wavy moving filter paper with a concave middle and convex sides, and in the middle of the second flow channel, vertical filtration is carried out through the square moving filter paper in the vertical direction, achieving uniform filtration and preventing local blockage.

[0017] In another technical solution, the vertical filtration component further includes a stirring mechanism. The stirring mechanism includes a control motor and a stirring frame. The stirring frame is rotatably installed on the side wall of the second flow channel, and the stirring frame faces the vertical filtration component. The control motor is arranged outside the second flow channel and is connected to the stirring frame.

[0018] Among them, the end of the stirring frame is provided with fan blades, which can produce an effect of guiding the liquid forward when rotating.

[0019] On this basis, multiple stirring frames are arranged in a group on the side wall of the second flow channel, and the multiple stirring frames are connected by a connecting belt.

[0020] In this technical solution, the control motor can drive multiple stirring frames to rotate. By using the stirring effect and guiding effect formed by the fan blades at the ends of the stirring frames, the plant protein beverage can be stirred and move towards the vertical partition filtration part in the center of the second flow channel, so that the plant protein beverage can pass through the partition filtration better.

[0021] As a further improvement of this technical solution, the inlet of the export channel is opened at the center of the top surface, and the shape of the inlet is the same as that of the narrow channel at the center of the bottom end of the second flow channel.

[0022] As a further improvement of this technical solution, sealable doors that can be opened are provided on the channels of the first flow channel and the second flow channel.

[0023] Compared with the prior art, the present invention provides a cylindrical filter for the production of plant protein beverages, which has the following

[0024] Beneficial effects:

[0025] Through the spatial arrangement of the concave guiding shaft rod and the vertical guiding shaft rod, the present invention enables the moving filter paper to form a wavy filtering cross-section with a convex middle and concave sides in the first flow channel. The electric driving member also drives the rotation of the rotating shafts wound around the four corners, so that the moving filter paper outside the rotating shafts wound around the four corners forms a vertically partitioned filtering surface at the center inside the second flow channel. At the same time, since the moving filter paper can move under the drive of its respective driving structure, during filtration, the plant protein beverage can be fully contacted with the moving filter paper, and the fluidity of the plant protein beverage in contact with the moving filter paper is increased, avoiding the influence of uneven pore size distribution of the filter paper on the filtration effect.

[0026] In addition, when the moving filter paper and the plant protein beverage move relative to each other, it is possible to prevent the surface of the filter paper from being occupied by solid particles and fine particles generated by filtration, preventing the influence on subsequent filtration.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0037] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown in the figure, the present invention provides a cylindrical filter for the production of plant protein beverages. In order to keep a part of the filter paper moving cyclically relative to the filtering area, so that the solution can evenly contact each part of the filter paper and avoid the influence of uneven pore size distribution of the filter paper on the content of fine particles and the effect of odor removal, a filter cylinder tank body for guiding materials and guiding the flow is provided here. The filter cylinder tank body includes an inlet cylinder 1 and a diversion channel 2 arranged below the inlet cylinder 1. The inlet cylinder 1 is a cylinder for introducing plant protein raw materials;

[0038] Refer to Figure 2 As shown in the figure, the diversion channel 2 includes a first flow channel 21, a second flow channel 22 and an outlet channel 23 arranged in sequence below the inlet cylinder 1;

[0039] It further includes a double-layer filtering mechanism. The double-layer filtering mechanism includes a horizontal filtering component 3 and a vertical filtering component 4. The horizontal filtering component 3 is arranged inside the first flow channel 21, and the vertical filtering component 4 is arranged at the connection of the second flow channel 22 and the outlet channel 23. Thus, the first layer of filtration is completed in the first flow channel 21, the second layer of filtration is completed in the second flow channel 22, and finally the filtered plant protein beverage is exported through the outlet channel 23. The vertical filtering component 4 is arranged directly below the horizontal filtering component 3.

[0040] Refer to Figure 2 and Figure 3As shown in the figure, the lateral filtration component 3 includes a moving filter paper 5 and a driving shaft group 32 for driving the moving filter paper 5 to move inside the filter cartridge body. The driving shaft group 32 includes a main driving motor 321, a winding shaft 322 arranged on both sides of the first flow channel 21, and a concave guiding shaft 323 arranged inside the first flow channel 21. The moving filter paper 5 passes through the first flow channel 21, and both ends of the moving filter paper 5 are respectively wound and connected to the two winding shafts 322, and the part of the moving filter paper 5 inside the first flow channel 21 bypasses the concave guiding shaft 323, so that a movable concave filtration structure is formed on both sides inside the first flow channel 21.

[0041] As Figure 3 and Figure 4 shown in the figure, the lateral filtration component 3 further includes a vertical guiding component 33. The vertical guiding component 33 includes an auxiliary driving motor 331 and a vertical guiding shaft 332. The vertical guiding shaft 332 is arranged in the upper half inside the first flow channel 21, and the auxiliary driving motor 331 is arranged outside the first flow channel 21 and connected to the vertical guiding shaft 332. The moving filter paper 5 bypasses the vertical guiding shaft 332, so that the vertical guiding shaft 332 forms an upward convex filtration structure in the middle of the first flow channel 21.

[0042] As Figure 8 shown in the figure, through the guiding of the moving filter paper 5 by the concave guiding shaft 323 and the vertical guiding shaft 332, a wavy filtration cross-section with a higher middle and lower sides is formed inside the first flow channel 21 for the moving filter paper 5, thereby increasing the filtration area with the plant protein beverage. At the same time, as the moving filter paper 5 moves, the wavy filtration cross-section can drive the plant protein beverage inside the first flow channel 21 to be in a flowing state, helping to increase the fluidity of the plant protein beverage and enhancing the filtration effect.

[0043] In addition, as Figure 8 shown in the figure, for this kind of wavy filtration cross-section with a higher middle and lower sides, during filtration, some large particle molecules and tiny particles will be deposited in the inner concave parts on both sides, resulting in a higher content of large particle molecules and tiny particles of the plant protein beverage in the inner concave parts than other positions. During the filtration process, when the first flow channel 21 is filled with the plant protein beverage, the plant protein beverage in the inner concave parts will be at the relatively lowest point. At this time, the plant protein beverage in the inner concave parts will be under the greatest liquid pressure. In this state, even if the plant protein beverage in the inner concave parts contains more large particle molecules and tiny particles, it can still quickly pass through the moving filter paper 5 to complete the filtration, avoiding the influence of the deposition of particle molecules and tiny particles on the filtration effect.

[0044] As Figure 2As shown, the second flow channel 22 is a funnel-shaped channel that is wider at the top and narrower at the bottom. The vertical filtration component 4 is disposed at the center of the second flow channel 22, and the bottom end of the vertical filtration component 4 abuts against the narrow channel portion of the second flow channel 22.

[0045] As Figure 5 and Figure 6 shown, the vertical filtration component 4 further includes a movable filter paper 5, a shielding arc top 42, and a built-in driving member 43. The shielding arc top 42 is disposed below the connection between the first flow channel 21 and the second flow channel 22. The built-in driving member 43 is vertically disposed below the shielding arc top 42. The movable filter paper 5 is wound around the outside of the built-in driving member 43, such that the movable filter paper 5 forms a vertically partitioned filtration surface at the center inside the second flow channel 22.

[0046] As Figure 6 shown, the built-in driving member 43 includes an electric driving member 431 and a four-corner winding rotating shaft 432. The electric driving member 431 is disposed inside the shielding arc top 42. The four-corner winding rotating shaft 432 is disposed at the four corners at the lower end of the shielding arc top 42. The electric driving member 431 is connected to one of the shaft bodies of the four-corner winding rotating shaft 432. The movable filter paper 5 is wound around the outside of the four-corner winding rotating shaft 432.

[0047] When the plant protein beverage enters the second flow channel 22, it flows through the channel that is wider at the top and narrower at the bottom of the second flow channel 22, and finally flows to the middle of the second flow channel 22. The movable filter paper 5 is vertically partitioned at the center of the second flow channel 22, such that the plant protein beverage will accumulate on the movable filter paper 5 and complete filtration.

[0048] As Figure 5 and Figure 7 shown, the vertical filtration component 4 further includes a flow stirring mechanism 41. The flow stirring mechanism 41 is located directly below the main filtration position of the horizontal filtration component 3. Referring to Figure 5 and Figure 7 shown, the flow stirring mechanism 41 includes a control motor 411 and a flow stirring frame 412. The flow stirring frame 412 is rotatably mounted on the side wall of the second flow channel 22, and the flow stirring frame 412 faces the vertical filtration component 4 directly. The end of the flow stirring frame 412 is provided with fan blades, which can generate an effect of guiding the liquid forward during rotation. The control motor 411 is disposed outside the second flow channel 22 and is connected to the flow stirring frame 412, such that the flow stirring frame 412 can be driven to rotate by the control motor 411. Thus, when the second flow channel 22 is filled with the plant protein beverage, agitation and lateral guidance of the plant protein beverage are formed, and the plant protein beverage is moved toward the side of the vertical filtration component 4.

[0049] A plurality of turbulence frames 412 are arranged in a group on the side wall of the second flow channel 22, and the plurality of turbulence frames 412 are connected by a connecting belt, so that the plurality of turbulence frames 412 are in a state of synchronous rotation.

[0050] It should be clear that the moving filter paper 5 inside the first flow channel 21 and the second flow channel 22 is in a moving state for filtration. This moving state can prevent the plant protein beverage with poor fluidity from being affected by the uneven pore diameters of the moving filter paper 5 during filtration, and at the same time increase the fluidity of the plant protein beverage at the contact position with the moving filter paper 5, further improving the filtration effect.

[0051] The inlet of the export channel 23 is opened at the center of the top surface, and the shape of the inlet is the same as that of the narrow channel at the center of the bottom end of the second flow channel 22, so that the plant protein beverage filtered by the moving filter paper 5 wound around the outer side of the rotating shaft 432 at the four corners will enter the export channel 23 and be finally exported.

[0052] Sealed doors that can be opened are provided on the channels of the first flow channel 21 and the second flow channel 22.

[0053] Since the plant protein beverage contains high protein and nutrients, when the beverage solution remains in the filtration equipment and the filter paper, the remaining beverage components will become a breeding ground for microorganisms, resulting in excessive bacteria and microorganisms in the plant protein beverage. At this time, the sealed doors on the first flow channel 21 and the second flow channel 22 can be opened to clean the inside of the first flow channel 21 and the second flow channel 22.

[0054] Working principle: The plant protein beverage is introduced through the feeding cylinder 1. At this time, the plant protein beverage will first fall into the first flow channel 21. At this time, the first layer of filtration of the plant protein beverage is formed by the moving filter paper 5 with a middle-high and two-side-low shape. During the process, the main drive motor 321 and the auxiliary drive motor 331 are started. Under the rotation guidance of the concave guiding shaft rod 323 and the vertical guiding shaft rod 332, the moving filter paper 5 can be moved. The wavy filtration cross-section, combined with the moving filter paper 5, enables the plant protein beverage and the filtration structure to complete the first layer of filtration in a relatively fast flowing state. At this time, the plant protein beverage falls into the second flow channel 22 and is guided to flow in the funnel-shaped channel with a wider upper part and a narrower lower part. When the second flow channel 22 is filled with the plant protein beverage, the control motor 411 can be started to drive a plurality of stirring frames 412 to rotate. At this time, the fan blades of the stirring frames 412 will guide the liquid towards the vertical filtration component 4. At this time, the electric drive member 431 drives the four-corner winding rotating shaft 432 to rotate, driving the moving filter paper 5 outside the four-corner winding rotating shaft 432 to rotate in a vertical direction in a circular motion. Since the moving filter paper 5 is horizontally arranged in the center of the second flow channel 22 in the vertical direction, the plant protein beverage will complete the second layer of filtration through the moving filter paper 5. Finally, the filtered plant protein beverage will fall into the export channel 23 and be exported.

[0055] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
