Description

Technical Field

[0001] This invention relates to the field of fruit kernel polyphenol extraction technology, and in particular to a near-infrared detection device for fruit kernel polyphenols that integrates automatic grinding, extraction and filtration. Background Technology

[0002] Extracting polyphenols from fruit kernels (such as areca kernels) has significant applications in food, health products, and cosmetics. Traditional fruit kernel polyphenol extraction processes typically involve crushing, extraction, and filtration. However, in actual industrial production, this process still has key factors affecting the yield, purity, and quality stability of the final polyphenol product: the uniformity of raw materials is a prerequisite for ensuring stable extraction quality. During collection and storage, fruit kernels may experience a significant reduction in internal polyphenol content due to mold, insect infestation, or other reasons. Current technologies typically involve directly feeding the raw materials into the crushing and extraction processes. If low-quality fruit kernels are fed into the crushing and extraction processes, it will affect the continuity of the supply of effective kernel fragments and lead to a reduction in the overall polyphenol content of all kernel fragments during subsequent extraction. This results in an over-feeding of the extractant, which in turn affects the purity and quality of the extracted polyphenols. Summary of the Invention

[0003] To overcome the shortcomings mentioned in the background art, the present invention provides a near-infrared detection device for fruit kernel polyphenols that integrates automatic grinding, extraction and filtration.

[0004] The technical solution is as follows: An integrated automatic grinding-extraction-filtration near-infrared detection device for fruit kernel polyphenols includes a base, a grinder mounted on the base, a feeder mounted on the grinder, a rotating housing rotatably connected to the feeder, a feeding housing rotatably connected to the rotating housing, a cyclone separator connected to the grinder, a pulse filter connected to the cyclone separator, a blower connected to the pulse filter, an extraction tank connected to the cyclone separator, a feeder located on the base near the feeder, a near-infrared detection module on the feeder, a fixed connection between the feeding housing and the feeder, a first electric push rod mounted on the feeder, a guide plate fixedly connected to the telescopic part of the first electric push rod, and a baffle slidably connected to the feeding housing fixedly connected to the guide plate.

[0005] Furthermore, the feeder is equipped with a motor, and the output shaft of the motor rotates with the rotating shell through a gear set. The feeder is fixedly connected to an inner liner located inside the rotating shell, and the inner liner is provided with a plurality of circumferentially distributed first separation holes.

[0006] Furthermore, a gap is provided between the rotating shell and the inner liner, and the distance of the gap gradually decreases from top to bottom.

[0007] Furthermore, the inner wall of the rotating shell is fixed with a plurality of crushing strips evenly distributed in the circumference, the width of the crushing strips gradually decreasing from top to bottom, and the crushing strips are located in the gap between the rotating shell and the inner liner.

[0008] Furthermore, the rotating shell has several circumferentially distributed second separation holes in its gaps.

[0009] Furthermore, the diameter of the second separation hole is smaller than the diameter of the first separation hole.

[0010] Furthermore, the second separation hole is located above the first separation hole.

[0011] Furthermore, the feeder is provided with an elastic part, and several micro-holes are provided on both sides of the elastic part.

[0012] Furthermore, the feeder is equipped with augers, and the pitch between the augers gradually decreases from the distance away from the grinder to the distance closer to it.

[0013] Furthermore, the base is fixedly connected to a lower pressure frame, the lower pressure frame is slidably connected to an upper pressure frame, the base is equipped with a second electric push rod, the telescopic part of the second electric push rod is fixedly connected to the upper pressure frame, and the lower pressure frame and the upper pressure frame are used to jointly compress the elastic part.

[0014] This invention has the following advantages: It temporarily stores a portion of the fruit kernels using a baffle. When the polyphenol content of the kernels on the feeder is insufficient, these kernels are discharged separately, and the kernels temporarily stored on the baffle enter the feed shell. This reduces the probability of damaged kernels entering the feed shell, ensuring the stability of the polyphenol content in the subsequent kernel fragments and reducing the probability of excessive polyphenol extract affecting the quality of the finished polyphenol product. The rotating shell drives all the crushing strips to rotate, compressing the kernels. As the kernels pass through the gradually narrowing gaps, they are gradually flattened, pre-crushing them and reducing subsequent grinding time. This reduces the impact of the high hardness of woody kernels and the long grinding time. This reduces the probability of the fruit kernel undergoing temperature rise and denaturation, thus ensuring the quality of the ground fruit kernel. Furthermore, during the flattening process, the fruit kernel first passes through all the second separation holes, and a large amount of white milky germ inside the kernel is squeezed out of the second separation holes, reducing ineffective substances in the subsequent fruit kernel polyphenol extraction process and improving the efficiency and quality of fruit kernel extraction. Utilizing the change in the screw pitch, the fruit kernel is compressed, with some kernels squeezing the elastic part. Simultaneously, the lower and upper pressure frames jointly squeeze the elastic part, compressing the fruit kernel fragments within it. The white milky germ within the fruit kernel fragments is squeezed out of the micropores of the elastic part, reducing ineffective substances in the subsequent fruit kernel polyphenol extraction process and improving the efficiency and quality of fruit kernel extraction.

Detailed Implementation

[0017] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] Example 1: Near-infrared detection equipment for fruit kernel polyphenols integrating automatic grinding-extraction-filtration, such as... Figures 1-4As shown, the system includes a base 1, a control terminal (not shown in the figure) mounted on the base 1, a grinder 101 electrically connected to the control terminal, and a feeder 102 installed on the base 1 to crush fruit kernels (referring to areca kernels). The feeder 102 conveys the fruit kernels into the grinder 101. A rotating shell 103 is rotatably connected to the feeder 102, and a feed inlet shell 104 is rotatably connected to the rotating shell 103. A cyclone separator 2 is connected to the grinder 101, and a pulse filter 3 electrically connected to the control terminal is connected to the cyclone separator 2. The pulse filter 3 is connected to a fan 4 electrically connected to the control terminal. The separator 2 is connected to the extraction tank 5, which is electrically connected to the control terminal. The fan 4 is used to control the flow direction of the fruit pit fragments after crushing. The cyclone separator 2 is used to separate the fruit pit fragments and dust, so that the dust enters the pulse filter 3 and the fruit pit fragments enter the extraction tank 5 for filtration. A feeder 6 is set on the base 1 near the feeder 102. The feeder 6 is equipped with a collection shell and a near-infrared detection module electrically connected to the control terminal. The feed shell 104 is fixedly connected to the feeder 6. The feeder 6 is equipped with a first electric push rod 7 electrically connected to the control terminal. The telescopic part of the first electric push rod 7 is fixedly connected to the guide plate 8. The telescopic part is used to drive the guide plate 8 to move. During the process of the feeder 6 feeding the fruit pits onto the guide plate 8, the polyphenol content in the fruit pits is detected by the near-infrared detection module. When the polyphenol content in the fruit pits is sufficient, the fruit pits enter the feed shell 104 through the guide plate 8. If the polyphenol content in the fruit pits is insufficient, the telescopic part of the first electric push rod 7 drives the guide plate 8 to move to the right. The guide plate 8 is fixedly connected to a baffle 9 that is slidably connected to the feed shell 104. The baffle 9 is a quarter-circular plate. Initially, the right side of the guide plate 8 does not contact the feed shell 104 to provide space for the guide plate 8 to move to the right. When the fruit pits enter the feed shell 104, they pass through the baffle. 9 blocks some fruit pits and temporarily stores others. When the polyphenol content of the fruit pits is insufficient due to mold and insect infestation, the guide plate 8 moves to the right and moves away from the feeder 6. The fruit pits on the feeder 6 no longer fall onto the guide plate 8, but instead fall into the collection shell of the feeder 6. The guide plate 8 drives the baffle 9 to move to the right, so that the fruit pits temporarily stored on the baffle 9 enter the feed shell 104. Under the premise of ensuring a stable amount of fruit pits fed into the feed shell 104, the probability of damaged fruit pits entering the feed shell 104 is reduced, thereby ensuring the stability of the polyphenol content in the subsequent fruit pit fragments and reducing the probability of excessive addition of polyphenol extractant affecting the quality of the polyphenol product.

[0019] like Figures 2-5As shown, the feeder 6 is equipped with a motor 10 electrically connected to the control terminal. The output shaft of the motor 10 rotates with the rotating housing 103 via a gear set, which consists of two spur gears. One spur gear is fixedly connected to the output shaft of the motor 10, and the other spur gear is fixedly connected to the rotating housing 103. The feeder 102 is fixedly connected to an inner liner 11 located inside the rotating housing 103. The inner liner 11 is provided with several circumferentially distributed first separation holes 12, which are used for the passage of crushed fruit pit fragments. A gap is provided between the rotating housing 103 and the inner liner 11, and the distance of the gap gradually decreases from top to bottom. The inner wall of the rotating shell 103 is fixed with several crushing strips 13 evenly distributed in the circumference. There is a distance between the crushing strips 13 and the inner liner 11. The width of the crushing strips 13 gradually decreases from top to bottom. The crushing strips 13 are located in the gap between the rotating shell 103 and the inner liner 11. The rotating shell 103 drives all the crushing strips 13 to rotate, so as to crush the fruit pits in the gap between the rotating shell 103 and the inner liner 11. The fruit pits are pre-crushed, reducing the subsequent fruit pit grinding time. This reduces the probability of fruit pits becoming deformed due to high hardness and long grinding time, thus ensuring the quality of the fruit pits after grinding.

[0020] The specific working principle is as follows: When the operator needs to grind, extract, filter, and test the polyphenols in the areca nuts, the feeder 6 conveys the nuts to the guide plate 8. During the process of the feeder 6 feeding the nuts into the guide plate 8, the polyphenol content in the nuts is detected by the near-infrared detection module. When the polyphenol content in the nuts is sufficient, the nuts enter the feed shell 104 through the guide plate 8. The baffle 9 blocks some of the nuts and temporarily stores some of them.

[0021] When the near-infrared detection module detects that the polyphenol content of the fruit pits is insufficient due to mold and insect infestation, the control terminal activates the first electric push rod 7. The telescopic part of the first electric push rod 7 drives the guide plate 8 to move to the right, away from the feeder 6. The fruit pits on the feeder 6 no longer fall onto the guide plate 8. The collection shell of the feeder 6 collects the fruit pits with insufficient polyphenol content separately. During the movement of the guide plate 8 to the right, the guide plate 8 drives the baffle 9 to move to the right, causing some of the fruit pits temporarily stored on the baffle 9 to be squeezed into the feed shell 104 and fall into the rotating shell 103. Under the premise of ensuring a stable amount of fruit pits fed into the feed shell 104, the probability of damaged fruit pits entering the feed shell 104 is reduced, thereby ensuring the stability of the polyphenol content in the subsequent fruit pit fragments and reducing the probability of excessive addition of polyphenol extractant affecting the quality of the polyphenol product. When the near-infrared detection module detects qualified fruit pits, the control terminal controls the telescopic part of the first electric push rod 7 to reset and close the first electric push rod 7.

[0022] After the fruit pits enter the rotating shell 103, the motor 10 is turned on through the control terminal. The output shaft of the motor 10 drives the rotating shell 103 to rotate through the gear set. The rotating shell 103 drives all the crushing strips 13 to rotate. The crushing strips 13 crush the fruit pits in the gap between the rotating shell 103 and the inner liner 11, pre-crushing the fruit pits and reducing the subsequent grinding time. This reduces the probability of the fruit pits becoming deformed due to their high hardness and long grinding time, thus ensuring the quality of the ground fruit pits.

[0023] After the fruit pits are crushed, the pit fragments enter the inner liner 11 through the first separation hole 12. The pit fragments then enter the grinder 101 through the feeder 102. The grinder 101 is turned on via the control terminal, and the grinder 101 crushes the fruit pits. The pulse filter 3 and the blower 4 are turned on via the control terminal, and the crushed pit fragments flow to the right and are separated by the cyclone separator 2. The separated dust enters the pulse filter 3 for filtration and collection. The separated pit fragments enter the extraction tank 5, and the extraction tank 5 is turned on via the control terminal. The extraction tank 5 extracts the fruit pit polyphenols. The above steps are repeated continuously to extract the fruit pits.

[0024] After the extraction of fruit kernel polyphenols is completed, the operator tests the purity of the extracted polyphenols and shuts down the grinder 101, pulse filter 3, blower 4, extraction tank 5 and motor 10 through the control terminal to clean the device for the next use.

[0025] Example 2: Based on Example 1 above, as follows Figure 4 and Figure 5 As shown, the rotating shell 103 has several circumferentially distributed second separation holes 14 in its gaps. During the process of the fruit pit being flattened, a large amount of white milky germ in the fruit pit located near all the second separation holes 14 is squeezed out of the second separation holes 14, reducing the ineffective substances in the subsequent fruit pit polyphenol extraction process and improving the efficiency and quality of fruit pit extraction (polyphenols are mainly concentrated in the woody structure of the fruit pit). The pore diameter of the second separation hole 14 is smaller than that of the first separation hole 12. The second separation hole 14 is located above the first separation hole 12 to ensure that the fruit pit is not completely crushed when the white milky germ in the fruit pit is squeezed out, reducing the amount of fruit pit debris squeezed out from the second separation hole 14 and improving the efficiency of separating the white milky germ from the fruit pit. The operator can periodically collect the white milky germ, or a collection shell can be set at the second separation hole 14 to collect the white milky germ.

[0026] Example 3: Based on Example 2 above, as follows Figure 4 and Figure 5As shown, the feeder 102 is provided with an elastic part 15. Several micro-holes are provided on both the front and rear sides of the elastic part 15. An auger 16 is provided inside the feeder 102. The pitch between the augers 16 gradually decreases from left to right. The augers 16 can be rotated by a motor. During the rotation of the augers 16, the crushed fruit kernels are guided into the grinder 101 from left to right. By changing the pitch of the augers 16, the fruit kernels on the right side of the augers 16 are further squeezed. Some of the fruit kernels squeeze the elastic part 15, and the white milky germ in the fruit kernel fragments is squeezed out of the micro-holes of the elastic part 15. The operator collects the white milky germ periodically.

[0027] like Figure 4 and Figure 5 As shown, a lower pressure frame 17 is fixedly connected to the base 1, and an upper pressure frame 18 is slidably connected to the lower pressure frame 17. A second electric push rod 19, which is electrically connected to the control terminal, is installed on the base 1. The telescopic part of the second electric push rod 19 is fixedly connected to the upper pressure frame 18. During the process of fruit pit fragments passing through the elastic part 15, the second electric push rod 19 is activated by the control terminal. The telescopic part of the second electric push rod 19 drives the upper pressure frame 18 to move up and down reciprocally. The lower pressure frame 17 and the upper pressure frame 18 jointly squeeze the elastic part 15, squeezing the fruit pit fragments in the elastic part 15, so that the white milky germ in the fruit pit fragments is squeezed out through the micropores of the elastic part 15, reducing the ineffective substances in the subsequent fruit pit polyphenol extraction process and improving the efficiency and quality of fruit pit extraction.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
