Description

Technical Field

[0001] This invention relates to the technical field of fruit and vegetable powder enzyme extraction equipment, and in particular to a fruit and vegetable powder extraction and separation device and process based on ultra-fine pulverization. Background Technology

[0002] Fruit and vegetable powders are rich in polyphenols, dietary fiber, and various bioactive components, and are widely used in the preparation of functional foods, health products, and antioxidants. Currently, the extraction of polyphenols from fruit and vegetable powders mainly employs solvent extraction, ultrasound-assisted extraction, or enzymatic extraction. However, existing extraction and separation equipment and processes still have the following problems in practical applications:

[0003] First, when fruit and vegetable powder is mixed with extract, due to the surface tension of water, the fine fruit and vegetable powder particles easily adsorb each other and form a bubble coating layer on the surface. This prevents the extract from fully contacting the effective components inside the particles, resulting in a low release rate of bound polyphenols. Although traditional stirring devices can provide a certain shear force, they are difficult to effectively break the bubble coating layer. Moreover, the vortex generated by stirring has a single direction, which can easily form mixing dead zones, causing solid particles to agglomerate and affecting the uniformity of extraction. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1, referring to Figures 1 to 8 This is the first embodiment of the present invention. This embodiment provides a fruit and vegetable powder extraction and separation device and process based on ultrafine pulverization. The fruit and vegetable powder extraction and separation device and process based on ultrafine pulverization includes a first fermenter 1 and a second fermenter 2. The premixed material is periodically impacted by the turbine disk 13 to form a vortex by the intermittent opening and closing of the fan blades 14, which breaks the bubble encapsulation and increases the contact area between the extract and the fruit and vegetable powder. The flow energy of the mixed liquid drives the filter rod 22 to rotate synchronously. With the upper and lower convection circulation, product inhibition is eliminated, and efficient enzymatic hydrolysis and continuous filtration separation are achieved.

[0039] Specifically, there is a first fermenter 1 and a second fermenter 2. The first fermenter 1 is equipped with a guide pipe 11, and the bottom of the first fermenter 1 is equipped with a return pipe 12 connected to the top of the second fermenter 2. Both the first fermenter 1 and the second fermenter 2 are made of stainless steel and welded together. The guide pipe 11 is vertically installed at the center of the interior of the first fermenter 1 and is fixed to the inner wall of the first fermenter 1 by welding. The return pipe 12 is welded to the center of the bottom of the first fermenter 1, and the other end of the return pipe 12 is connected to the top flange of the second fermenter 2. The return pipe 12 is used to pump the mixed liquid at the bottom of the first fermenter 1 back to the top of the second fermenter 2 to form a circulation flow, thereby prolonging the residence time of the mixed liquid in the fermentation system, improving the efficiency of the enzymatic hydrolysis reaction, and effectively improving the full mixing of the fruit and vegetable powder raw materials and the extract participating in the reaction during the rolling process of the mixed liquid.

[0040] Specifically, the top end of the guide pipe 11 is provided with a turbine disk 13, and the top end of the guide pipe 11 is also provided with fan blade fins 14. The fan blade fins 14 are connected to a deflector plate 15, and the deflector plate 15 is connected to a sinking ring 16. The drive assembly 3 is located inside the first fermenter 1 and is used to control the deflection of the fan blade fins 14. The turbine disk 13 is rotatably installed inside the top end of the guide pipe 11. The blades of the turbine disk 13 are distributed in a ring array. The outer periphery of the top end of the guide pipe 11 is provided with fan blade fins 14. The fan blade fins 14 are evenly distributed along the circumference of the guide pipe 11. The outer end of each fan blade fin 14 is fixedly connected to a vertically arranged deflector plate 15. The top end of the deflector plate 15 is provided with a drive groove. The sinking ring 16 is provided with a short shaft at a position corresponding to the drive groove. The short shaft is inserted into the drive groove and has a ball head that is slidably provided. The drive assembly 3 is installed on the upper side inside the first fermenter 1, and one of the deflector plates 15 is extended. Figure 6 As shown, the output end of the drive component 3 is connected to this dial 15 to control the synchronous deflection angle of the fan blade 14.

[0041] When the fan blade fins 14 deflect, the gap between the fan blade fins 14 changes, causing the upper opening of the guide pipe 11 to be in an open-closed state. When the material enters, the upper opening of the guide pipe 11 is in a closed state, allowing the material to accumulate at the opening of the guide pipe 11. After a period of time, the guide pipe 11 opens, and the accumulated material falls rapidly, impacting the worm gear disk, causing the turbine disk 13 to rotate and continuously agitate the flowing material, making it fully dispersed. After being guided by the guide pipe 11, it is mixed at the bottom of the first fermentation tank 1, achieving automatic stirring in the form of dispersion and mixing, improving the mixing of fruit and vegetable powder raw materials and extract, and improving the efficiency and effect of fermentation.

[0042] Specifically, the bottom end of the guide pipe 11 is provided with a flow channel 17, which is connected to an extension pipe 18. The top end of the guide pipe 11 is provided with a secondary pipe 19. A ring groove is formed around the bottom of the guide pipe 11 as the flow channel 17. An extension pipe 18 is welded to the bottom of one side of the flow channel 17. The extension pipe 18 horizontally penetrates the side wall of the first fermenter 1 and extends outward. A secondary pipe 19 is welded to one side of the top end of the guide pipe 11. The secondary pipe 19 is inclined upward and penetrates the top cover of the first fermenter 1. The extension pipe 18 is used to directly introduce part of the mixture into the bottom of the guide pipe 11, and the secondary pipe 19 is used to introduce another part of the mixture into the top of the guide pipe 11. The two together realize two-way liquid inlet from the top and bottom, forming convection and collision in the guide pipe 11, which greatly enhances the mixing effect.

[0043] Specifically, when the mixture of fruit and vegetable powder and extract flows to the bottom of the first fermentation tank 1, the peristaltic pump installed at the bottom of the first fermentation tank 1 pumps the material into the interior of the second fermentation tank 2 through the return pipe 12. After being filtered by the second fermentation tank 2, the fiber and other water-insoluble solids in the fruit and vegetable powder raw material are filtered out and fall to the bottom of the second fermentation tank 2. At this time, the sensor installed at the bottom of the second fermentation tank 2 senses the extraction progress. If the reaction is complete, the controller opens the drain port at the bottom of the second fermentation tank 2 to discharge the extracted material. Otherwise, it is introduced into the interior of the mixing pipe 23 through the inlet pipe 24, and then pumped into the interior of the extension pipe 18 and the secondary pipe 19 through the mixing pipe 23, so that the material is diverted into the upper and lower parts of the guide pipe 11, and then impacted again to form a secondary mixture when they converge.

[0044] Specifically, the second fermentation tank 2 is equipped with a partition 21 with filter rods 22, a linkage assembly 4 which is located at the top inside the second fermentation tank 2 to drive the filter rods 22 to rotate, and a mixing pipe 23 connected to the sub-pipe 19 and the first fermentation tank 1. The mixing pipe 23 is also connected to an inlet pipe 24, which is connected to the bottom of the second fermentation tank 2. A horizontal partition 21 is fixedly installed at the bottom inside the second fermentation tank 2. The partition 21 has multiple round holes, and a filter rod 22 is rotatably installed in each round hole. The linkage assembly 4 is installed at the top inside the second fermentation tank 2. The lower end of the linkage assembly 4 is connected to the upper end of the filter rods 22 to drive all the filter rods 22 to rotate synchronously.

[0045] The mixing pipe 23 is a three-way pipe structure. One port of the mixing pipe 23 is connected to the flange of the auxiliary pipe 19, and the other port is connected to the flange of the middle side wall of the first fermentation tank 1. The third port of the mixing pipe 23 is welded with the inlet pipe 24. The inlet pipe 24 extends downward and is connected to the flange of the bottom side wall of the second fermentation tank 2. The function of the mixing pipe 23 is to mix the fruit and vegetable powder and the extract evenly before the mixed liquid enters the first fermentation tank 1, and to send part of the mixed liquid directly into the bottom of the second fermentation tank 2 for filtration and separation through the inlet pipe 24, so as to avoid solid particles from settling at the bottom of the tank.

[0046] Example 2, refer to Figures 1 to 8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0047] Specifically, the guide pipe 11 has a support platform 110 inside, and the support platform 110 is fixedly connected to the guide pipe 11 through several connecting plates 111. The turbine disk 13 is rotatably mounted on the top of the support platform 110 through a rotating shaft 112. A conical support platform 110 is welded to the center of the inside of the guide pipe 11, and the support platform 110 is welded and fixed to the inner wall of the guide pipe 11 through multiple connecting plates 111.

[0048] A vertical rotating shaft 112 is connected to the center key of the turbine disk 13. The upper end of the rotating shaft 112 is installed in the center hole of the top of the support platform 110 through a ball bearing. During installation, the rotating shaft 112 is first inserted into the bearing of the support platform 110, and then the turbine disk 13 is fixed to the upper end of the rotating shaft 112. When the mixture impacts the turbine disk 13 from above the guide pipe 11, the turbine disk 13 drives the rotating shaft 112 to rotate, so that the mixture is dispersed as much as possible when it flows downward, avoiding the phenomenon of material agglomeration. Furthermore, when multiple materials impact each other, the reaction effect can be further improved.

[0049] Specifically, the top end of the guide pipe 11 is provided with a guide ring 113, and the guide ring 113 is supported by a support platform 114 via an optical axis bracket. The fan blade fins 14 are disposed inside the support platform 114. One end of the fan blade fins 14 passes through the guide ring 113, and the other end extending out of the guide ring 113 is connected to a lever plate 15. The top end of the lever plate 15 is provided with a drive groove, such as... Figure 6 As shown, a short shaft is provided at the position corresponding to the drive groove of the sinking ring 16. The short shaft is inserted into the drive groove and is provided with a ball head. A circular guide ring 113 is fixedly provided on the outer periphery of the top end of the guide pipe 11. A support platform 114 is fixedly supported above the guide ring 113 by an optical axis bracket. One end of the optical axis bracket is welded to the guide ring 113 and the other end is welded to the support platform 114.

[0050] The fan blade fins 14 can be spliced ​​together to form a ring, and each fan blade fin 14 has a soft pad on its outer periphery to improve sealing, so that a temporary storage cavity can be formed between the fan blade fin 14, the base 114 and the guide ring 113. Furthermore, the inner and outer sides of the fan blade fin 14 are fixedly connected to the rotating shaft by rivets, and the rotating shafts at both ends are inserted into the base 114 and the guide ring 113 respectively, and can rotate freely. The rotating shaft that passes through the guide ring 113 is welded and fixed to the lower end of the deflector plate 15. When the sinking ring 16 rotates, it drives all the deflector plates 15 to swing synchronously through the short shaft, thereby causing the fan blade fin 14 to deflect around its inner end pin, so as to achieve centralized adjustment.

[0051] Specifically, the drive assembly 3 includes a horizontally positioned control push rod 31 and a cylindrical sleeve 32 fitted around the control push rod 31. The outer wall of the sleeve 32 is welded and fixed to the inner wall of the first fermentation tank 1 via an angle steel bracket. A helical spring 33 is coaxially installed inside the sleeve 32. The spring 33 is fitted around the control push rod 31. The left end of the spring 33 is welded and fixed to the inner wall of the left end of the sleeve 32, and the right end of the spring 33 is welded and fixed to the outer wall of the right end of the control push rod 31. A cam 34 is installed on the outer left side of the sleeve 32 via a bearing seat. The left end of the control push rod 31 is always in elastic contact with the outer wall of the cam 34 under the thrust of the spring 33. The right end of the control push rod 31 passes through the right end opening of the sleeve 32 and is rotatably connected to the bottom end of one of the lever plates 15 via a pin.

[0052] A drive motor 35 is fixedly mounted on the outer periphery of the guide pipe 11 via a motor bracket. The output shaft of the drive motor 35 is connected to the central shaft of the cam 34 via a coupling to drive the cam 34 to rotate. When the cam 34 rotates, the control push rod 31 performs reciprocating linear motion, thereby pushing the dial plate 15 to swing. The cam 34 consists of two concentric semicircles with a significant difference in diameter. When the smaller semicircle of the cam 34 contacts the control push rod 31, the fan blade 14 is in an open state, allowing the mixed liquid to pass through the fan blade 14 and be discharged. When the larger semicircle of the cam 34 contacts the control push rod 31, the fan blade 14 is in a closed state, allowing the material to accumulate inside the temporary storage chamber, thus achieving the initial mixing of fruit and vegetable powder and extract.

[0053] Specifically, the transfer trough 17 is an annular channel with a U-shaped cross-section surrounding the outer wall of the bottom end of the guide pipe 11. The inner end of the extension pipe 18 is connected to one end of the transfer trough 17. The outer end of the extension pipe 18 passes through the side wall of the first fermentation tank 1 and is welded with a flange for connecting external pipelines. The secondary pipe 19 is welded to the right side of the top end of the guide pipe 11. The air outlet of the secondary pipe 19 is located above the guide ring 113 to facilitate the introduction of the mixed liquid into the interior of the temporary storage chamber. The secondary pipe 19 is inclined upward and passes through the top cover of the first fermentation tank 1. The penetration is sealed by welding to facilitate secondary separation and remixing of the materials.

[0054] Specifically, the partition plate 21 is horizontally welded and fixed to the bottom of the second fermenter 2, and has a cavity with the bottom of the tube of the second fermenter 2. Several circular rotating holes 25 are evenly opened on the partition plate 21. A bearing is installed on the inner wall of each rotating hole 25. The upper end journal of the filter rod 22 is inserted into the bearing to achieve rotational engagement. A closed annular transmission cavity 26 is opened inside the partition plate 21. The same number of toothed rings 27 as the filter rods 22 are installed in the transmission cavity 26. Each toothed ring 27 is fixedly sleeved on the outer peripheral wall of the corresponding filter rod 22 by a key connection. Adjacent toothed rings 27 directly mesh with each other. When one filter rod 22 rotates, all filter rods 22 are driven to rotate synchronously through the meshing transmission of the toothed rings 27. Furthermore, a brush plate is provided on the outer peripheral side of the filter rod 22. The brush plates of adjacent filter rods 22 are staggered. Therefore, the rotating filter rod 22 can prevent the filter holes from clogging.

[0055] Specifically, the linkage assembly 4 includes a vertically arranged linkage pipe 41. The upper end of the linkage pipe 41 is connected to the outlet end of the return pipe 12 through a flange and is interconnected with it. A ball head 42 is welded to the bottom end of the linkage pipe 41. The ball head 42 is a hollow sphere. A worm gear 43 is rotatably installed inside the linkage pipe 41 through two bearings. The upper end of the worm gear 43 is located inside the linkage pipe 41, and the lower end of the worm gear 43 passes downward through the central hole of the ball head 42 and extends into the interior of the second fermenter 2.

[0056] The lower end of the worm gear 43 is connected to the upper end of the filter rod 22 located at the center through a planetary gear set 44. The planetary gear set 44 includes a sun gear fixed to the lower end of the worm gear 43, a gear ring fixed to the upper end of the central filter rod 22, and a planet carrier and planet gears installed between the two. When the mixture flows from the return pipe 12 into the linkage pipe 41, the liquid impacts the helical blades on the worm gear 43, driving the worm gear 43 to rotate. This, in turn, drives the central filter rod 22 to rotate at a low speed and high torque through the planetary gear set 44. At the same time, the other filter rods 22 are driven to rotate synchronously through the gear ring 27.

[0057] Specifically, multiple sets of flat grooves 45 penetrating the wall thickness are evenly opened on the outer peripheral wall of the ball head 42. The cross-sectional shape of the flat groove 45 is conical, that is, the width of the outer side of the groove opening is greater than the width of the inner side. The flat groove 45 is used to disperse the return liquid and avoid concentrated impact. The mixing pipe 23 is a stainless steel welded tee pipe. The three ports of the mixing pipe 23 are respectively connected to the auxiliary pipe 19, the middle side wall of the first fermentation tank 1 and the inlet pipe 24 through flanges. All connections are padded with sealing gaskets.

[0058] Specifically, a detachable upper cover 5 is fixed to the upper opening of the first fermentation tank 1 by bolts. A rubber sealing ring is placed between the upper cover 5 and the first fermentation tank 1. A funnel-shaped feed hopper 115 is welded to the top of the guide pipe 11. The large opening of the feed hopper 115 faces upward and corresponds to the center position of the lower surface of the upper cover 5. A gap is left between the feed hopper 115 and the upper cover 5 to prevent material impact damage. A cylindrical feed inlet 51 is welded to the center position of the top of the upper cover 5. The upper end of the feed inlet 51 is equipped with a quick-release clamp for connecting the feed pipeline. During installation, the guide pipe 11 is first hoisted into the first fermentation tank 1 as a whole and welded and fixed. Then the upper cover 5 is covered. Finally, the material is fed in through the feed inlet 51.

[0059] Example 3, referring to Figures 1-9 This is the third embodiment of the present invention. This embodiment is based on a production process of a fruit and vegetable powder extraction and separation device based on ultrafine pulverization, as described in the first two embodiments, and includes the following steps:

[0060] S1. The dried fruit and vegetable raw materials are ultra-finely pulverized and sieved to obtain fruit and vegetable powder. An ultra-fine pulverizer is used to process the dried fruit and vegetable raw materials, controlling the particle size between 200 and 500 mesh. This particle size range effectively disrupts plant cell walls, increasing the release rate of intracellular polyphenols and other effective components during subsequent enzymatic hydrolysis. The pulverized material is then sieved through a vibrating screen to remove insufficiently pulverized coarse particles, ensuring uniform particle size of the resulting fruit and vegetable powder. The sieved fruit and vegetable powder has a significantly increased specific surface area, which facilitates full contact with the extraction liquid. Compared to ordinary pulverization, ultra-fine pulverization can increase the cell wall disruption rate to over 90%, thereby improving extraction efficiency without using organic solvents or with reduced solvent usage.

[0061] S2. The fruit and vegetable powder obtained in step S1 is mixed with the extract at a ratio of 1g / 8mL to 1g / 15mL. The mixture is fed into the first fermentation tank 1 through the feed inlet 51 at the top of the upper cover 5. At this time, the fan blade 14 is in a closed state. The mixture falls through the feed hopper 115 into the temporary storage chamber formed by the fan blade 14, the support 114 and the guide ring 113. In the temporary storage chamber, the mixture stays, and the fruit and vegetable powder and the extract undergo preliminary wetting and diffusion during this process to achieve premixing. This premixing step can prevent the fruit and vegetable powder from falling directly to the bottom of the tank and forming clumps. At the same time, it can make the surface of the solid particles uniformly adsorb the extract, creating good conditions for subsequent impact dispersion. The temporary storage time is controlled by the drive component 3. If the time is too short, the wetting will be insufficient. If the time is too long, the material will begin to separate and precipitate.

[0062] S3. Start the drive motor 35 to drive the cam 34 to rotate. The cam 34 consists of two concentric semicircles with a significant difference in diameter. When the smaller semicircle of the cam 34 contacts the control push rod 31, the control push rod 31 extends outward under the action of the spring 33, pushing the dial plate 15 to swing, causing the fan blade 14 to deflect around its axis to the open state; when the larger semicircle of the cam 34 contacts the control push rod 31, the control push rod 31 is pushed back inward, and the fan blade 14 returns to the closed state.

[0063] At the moment the fan blade fins 14 open, the premixed material accumulated in the temporary storage chamber falls rapidly under the action of gravity. The premixed material impacts the spiral blades of the turbine disk 13 vertically, driving the turbine disk 13 to drive the rotating shaft 112 to rotate at high speed on the support platform 110. The rotation of the turbine disk 13 transforms the falling premixed material into a downward vortex, which fully disperses the solid particles in the liquid and avoids agglomeration. The premixed material dispersed by the vortex flows downward along the guide pipe 11 and enters the bottom area of ​​the first fermentation tank 1 through the bottom transfer groove 17 and extension pipe 18.

[0064] S4. After all the premixed material enters the bottom of the first fermentation tank 1, start the peristaltic pump on the return pipe 12 to pump the mixture at the bottom of the first fermentation tank 1 to the top of the second fermentation tank 2. The mixture first enters the linkage pipe 41, impacts the spiral blades on the worm gear 43, drives the worm gear 43 to rotate, and then drives all the filter rods 22 to rotate synchronously and slowly through the planetary gear set 44 and the gear ring 27. After the mixture is dispersed and sprayed out through the conical flat groove 45 on the ball head 42, it is filtered through the filter rods 22 and enters the bottom cavity of the second fermentation tank 2.

[0065] S5. After enzymatic hydrolysis, all the mixture flows into the second fermenter 2 through the reflux pipe 12. In the second fermenter 2, the mixture undergoes solid-liquid separation by gravity through a rotating filter rod 22. The filter rod 22 is a hollow cylinder with 10μm to 50μm filter holes on the cylinder wall and is covered with a nylon or stainless steel filter screen. Driven by the linkage component 4, the filtered clear filtrate passes through the partition 21 and enters the cavity at the bottom of the second fermenter 2, while the solid residue is trapped on the outer periphery of the filter rod 22 above the partition 21. After the filtrate is collected, the drain port at the bottom of the second fermenter 2 is opened to discharge the filtrate. The filtrate is concentrated to 1 / 8 to 1 / 12 of its original volume using a rotary evaporator or vacuum concentrator at 40℃ to 50℃ to obtain a viscous fruit and vegetable powder extract, which can be directly spray-dried into powder by subsequent equipment or freeze-dried and stored.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
