Description

Technical Field

[0001] This utility model relates to the field of dietary fiber extraction technology, specifically to an ultrasonic pretreatment device for extracting dietary fiber from pine nut meal. Background Technology

[0002] As a new industry, plant extraction is receiving increasing attention from the pharmaceutical and food industries. Plant extracts are made from plants as raw materials and are extracted and separated through a physicochemical process according to the needs of the final product. Ultrasonic stirring devices can be used to fully stir and extract the materials.

[0003] For example, the authorization announcement number CN222368869U is an ultrasonic device for extracting dietary fiber from highland barley. This device includes a drive motor, a rotating rod, and a first support plate. The drive motor, rotating rod, and first support plate drive two connecting rods, a second support plate, and scrapers to rotate. This not only allows the stirring rods on the outer surfaces of the two connecting rods to evenly stir the raw materials inside the extraction chamber, but also drives the two scrapers to rotate inside the extraction chamber, thus scraping off the viscous material adhering to the inner wall of the extraction chamber. However, during use, the distance between the scraper and the extraction chamber cannot be adjusted, causing wear and tear on the scraper due to prolonged contact with the extraction chamber. This results in gaps between the extraction chamber and the scraper, affecting the cleaning effect on the extraction chamber. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art by proposing an ultrasonic pretreatment device for extracting dietary fiber from pine nut meal.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an ultrasonic pretreatment device for extracting dietary fiber from pine nut meal, including an extraction cylinder, an outer shell, and a stirring mechanism. The outer shell is provided on the outside of the extraction cylinder, and the stirring mechanism is provided inside the extraction cylinder. The stirring mechanism includes a stirring main rod, a connecting block, a connecting rod, a sleeve block, a support rod, a sleeve rod, a scraper, a stirring auxiliary rod, a screw, and a slider.

[0007] The upper side of the stirring main rod is rotatably connected to the extraction cylinder. A connecting block is rotatably provided in the middle section of the stirring main rod. Both sides of the connecting block are rotatably connected to connecting rods. The end of the connecting rod away from the connecting block is rotatably connected to a sleeve block. Both sides of the sleeve block are hinged to support rods. The end of the sleeve block away from the support rod is rotatably connected to a sleeve rod. The inner walls of multiple sleeve rods are slidably connected to the stirring body. The ends of the sleeve rods on both sides are fixedly connected to scrapers. The inner walls of the sleeve blocks on both sides are sleeved to the stirring main rod. Stirring auxiliary rods are provided on both sides of the stirring main rod. The middle part of the upper sleeve block is fixedly connected to a slider. The end of the slider is rotatably connected to a screw. The outer wall of the screw is threadedly connected to the stirring main rod.

[0008] Preferably, a first gear is provided on the side of the stirring main rod adjacent to the screw, and the outer wall of the first gear meshes with a second gear.

[0009] Preferably, the extraction cylinder has a feed inlet on one side of its upper end and a discharge valve at its lower end, with the discharge valve extending out of the outer shell.

[0010] Preferably, a support is provided on the other side of the upper end of the extraction cylinder, and a drive assembly is provided in the middle of the support. The output shaft of the drive assembly is fixedly connected to the second gear.

[0011] Preferably, an ultrasonic generator is provided inside the outer shell, and an ultrasonic vibrator is provided at the bottom of the extraction cylinder.

[0012] The present invention provides an ultrasonic pretreatment device for extracting dietary fiber from pine nut meal. The advantages are as follows: By rotating the screw, the screw can move along the threaded groove of the mixing rod. The connecting block moves downwards via the connecting rod on the other side, while the sleeve block drives the support rods on both sides to rotate simultaneously. The support rods drive the sleeve rods to move left and right, causing the scrapers on both sides to come into contact with the extraction cylinder. Then, the drive assembly is controlled to rotate, causing the scrapers to move circumferentially along the inner wall of the extraction cylinder, thereby cleaning the inside of the extraction cylinder. After cleaning, the drive assembly is turned off, and the screw is rotated in the opposite direction, causing the scrapers on both sides to separate from the inner wall of the extraction cylinder. This avoids the problem of wear and tear caused by prolonged contact between the scrapers used to clean the extraction cylinder during the raw material mixing process, which can affect the cleaning effect.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] See attached document Figure 1-3 To address the problem in existing technologies where the scraper used for cleaning the extraction cylinder during the raw material mixing process is prone to wear due to prolonged contact with the extraction cylinder, thus affecting the cleaning effect, an ultrasonic pretreatment device for extracting dietary fiber from pine nut meal is proposed. The device includes an extraction cylinder 1, a shell 2, and a stirring mechanism 4. The shell 2 is located on the outside of the extraction cylinder 1, and the stirring mechanism 4 is located inside the extraction cylinder 1. The stirring mechanism 4 includes a stirring main rod 401, a connecting block 402, a connecting rod 403, a sleeve block 404, a support rod 405, a sleeve rod 406, a scraper 407, a stirring auxiliary rod 408, a screw 409, and a slider 410.

[0019] The upper side of the stirring main rod 401 is rotatably connected to the extraction cylinder 1. A connecting block 402 is rotatably installed in the middle section of the stirring main rod 401. Both sides of the connecting block 402 are rotatably connected to the connecting rod 403. The end of the connecting rod 403 away from the connecting block 402 is rotatably connected to the sleeve block 404. Both sides of the sleeve block 404 are hinged to the support rod 405. The end of the sleeve block 404 away from the support rod 405 is rotatably connected to the sleeve rod 406. The inner walls of the multiple sleeve rods 406 are slidably connected to the stirring body. The ends of the sleeve rods 406 on both sides are fixedly connected to the scraper 407. The inner walls of both sleeve blocks 404 are fitted onto the main stirring rod 401. A secondary stirring rod 408 is provided on each side of the main stirring rod 401. The middle of the upper sleeve block 404 is fixedly connected to the slider 410. The end of the slider 410 is rotatably connected to the screw 409. The outer wall of the screw 409 is threadedly connected to the main stirring rod 401. A handle is provided at the end of the screw 409 away from the slider 410 for easy rotation. The screw 409 can move up and down along the threaded groove of the main stirring rod 401. As the screw 409 rotates on the slider 410, it drives the slider 410 to rotate. The slider 410 moves up and down, causing the upper sleeve block 404 to move up and down. The upper sleeve block 404 causes the connecting rod 403 on the same side to rotate. The connecting rod 403 on this side causes the connecting block 402 to rotate. The connecting block 402 rotates along the stirring main rod 401, simultaneously causing the connecting rod 403 on the other side to rotate, so that the connecting blocks 402 on both sides move simultaneously, and the directions of movement of the connecting blocks 402 on both sides are opposite. At the same time, the sleeve block 402 causes the support rods 405 on both sides to rotate simultaneously. The support rods 405 cause the sleeve rod 406 to move left and right, so that the scrapers on both sides... 407 is either in contact with or has a certain gap from the extraction cylinder 1. A rubber ring is provided between the inner wall of the sleeve 404 and the stirring main rod 401 to ensure that the sleeve 404 can slide on the outer wall of the stirring main rod 401 while preventing the raw material from being embedded in the gap between the sleeve 404 and the stirring main rod 401. At the same time, a rubber ring is provided between the sleeve rod 406 and the stirring main rod 401 to prevent the raw material from being embedded in the gap between the sleeve rod 406 and the stirring main rod 401. The stirring main rod 401 can drive the stirring auxiliary rod 408 and the scraper 407 to move circumferentially to stir and mix the raw material.

[0020] A first gear 5 is provided on one side of the stirring rod 401 adjacent to the screw 409. The outer wall of the first gear 5 meshes with the second gear 6. A feed inlet 102 is provided on one side of the upper end of the extraction cylinder 1. A discharge valve 101 is provided at the lower end of the extraction cylinder 1 and extends out of the outer shell 2. A bracket 7 is provided on the other side of the upper end of the extraction cylinder 1. A drive assembly 8 is provided in the middle of the bracket 7. The output shaft of the drive assembly 8 is fixedly connected to the second gear 6. An ultrasonic generator 9 is provided inside the outer shell 2. An ultrasonic vibrator 3 is provided at the bottom of the extraction cylinder 1. The drive assembly 8 is preferably a motor. The output shaft of the drive assembly 8 drives the second gear 6 to rotate. The second gear 6 drives the first gear 5 to rotate. The first gear 5 drives the stirring rod 401 to rotate.

[0021] Working principle:

[0022] Pine nut meal is poured into the extraction cylinder 1 through the feed inlet 102. The output shaft of the drive assembly 8 drives the second gear 6 to rotate. The second gear 6 drives the stirring rod 401 to rotate through the first gear 5. The stirring rod 401 drives the scraper 407 to drive the stirring auxiliary rod 408 to move circumferentially to stir the raw material. At this time, the scraper 407 does not contact the inner wall of the extraction cylinder 1. The ultrasonic generator 9 and ultrasonic vibrator 3 perform ultrasonic extraction on the raw material in the extraction cylinder. After extraction, the material is discharged through the discharge valve 101 and the drive assembly 8 is turned off. Before cleaning the extraction cylinder, the screw 409 is rotated. The screw 409 can move along the thread groove of the stirring rod 401. The screw 409 rotates on the slider 410 and drives the slider 410 to move. The slider 410 can drive the upper sleeve block 404 to move. The upper sleeve block 404, connected by a connecting rod 403 on the same side, rotates the connecting block 402. The connecting block 402, through the connecting rod 403 on the other side, moves the lower connecting block 402 downward. Simultaneously, the sleeve block 402 rotates the support rods 405 on both sides, which in turn move the sleeve rod 406 left and right, causing the scrapers 407 on both sides to come into contact with the extraction cylinder 1. Then, the drive assembly 8 is controlled to rotate, causing the scrapers 407 to move circumferentially along the inner wall of the extraction cylinder 1, thereby cleaning the inside of the extraction cylinder. After cleaning, the drive assembly 8 is turned off, and the screw 409 is rotated in the opposite direction, causing the scrapers 407 on both sides to separate from the inner wall of the extraction cylinder 1. This avoids the problem that the scrapers used to clean the extraction cylinder during the mixing of raw materials are in contact with the extraction cylinder for a long time, which can easily cause wear and affect the cleaning effect of the extraction cylinder.

[0023] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
