Description

Technical Field

[0001] This invention relates to the field of soybean processing technology, specifically to a tube bundle dryer for dehydrating soybean dietary fiber based on vibration feeding. Background Technology

[0002] Soybean dietary fiber is an important byproduct of the soybean processing industry. In the industrial processing of soybean dietary fiber, dehydration and drying is the core and key process. The effect of the drying process directly determines the quality of the finished dietary fiber, the retention rate of active ingredients, the product moisture content and shelf life. It is the core link to ensure product quality and production efficiency.

[0003] Currently, the industry generally uses traditional tubular drying equipment to dry soybean dietary fiber. However, this traditional equipment has many inherent technical defects and shortcomings in the actual production conditions specific to soybean dietary fiber, which seriously restricts the improvement of the quality of soybean dietary fiber products and the continuous and efficient production.

[0004] Conventional tube bundle drying equipment uses a fixed structure of rotor tube bundles and lifting plate assemblies. The material turning mode is singular and the material disturbance effect inside the drum is poor. It cannot adapt to the material characteristics of soybean dietary fiber, which is light in texture, has high porosity, and is very easy to agglomerate after absorbing water. Moreover, during the drying process, the agglomerated fiber material cannot be effectively dispersed, and it is easy to form local accumulation inside the drying drum, resulting in a large area of ​​drying blind zone. This causes uneven drying of the material as a whole, and the finished product has significant differences in dryness and moisture content, which greatly reduces the product qualification rate and batch production stability.

[0005] To address the aforementioned technical deficiencies, a solution is proposed that aims to optimize the material disturbance and dispersion effect during the drying process of soybean dietary fiber, thereby achieving high-precision, high-stability, and high-efficiency drying and processing of soybean dietary fiber. Summary of the Invention

[0006] The purpose of this invention is to achieve radial adaptive adjustment and axial slight fluctuation of the rotor tube bundle by utilizing an elastic floating installation mechanism. Combined with elastic composite lifting plates of different lengths and angles, it can effectively disperse fiber agglomerates, eliminate drying blind spots and material accumulation. Furthermore, it relies on the impact tooth plate assembly to construct a non-powered self-excited vibration and adaptive differentiated cleaning system, which can actively peel off adhering materials and automatically clean the lifting plates, eliminating the need for separate operation and making it suitable for large-scale continuous industrial drying production.

[0007] The objective of this invention can be achieved through the following technical solution: a tube bundle dryer for dehydrating soybean dietary fiber based on vibration feeding, comprising a sealed horizontal cylinder, a spiral conveyor, multiple sets of rotor tube bundles, a steam heat exchange assembly, and a micro negative pressure dehumidification assembly;

[0008] The spiral conveying component includes a conveying pipe and a matching spiral conveying rod. The conveying pipe is integrally fixedly installed on one side of the front end of the cylinder, and the spiral conveying rod is provided inside the conveying pipe.

[0009] Multiple sets of rotor tube bundles are arranged along the transverse circumference inside the cylinder, and an elastic floating installation mechanism is provided on the outside of the rotor tube bundles. The rotor tube bundles are installed inside the cylinder through the elastic floating installation mechanism, which can realize radial adjustment and axial controllable fluctuation. Irregular staggered composite lifting plates are welded and fixed on the outside of the rotor tube bundles.

[0010] The steam heat exchange component is located at the center of the top surface of the cylinder and at the end of the cylinder away from the conveying pipe. The steam heat exchange component is used to provide a stable heat source into the cylinder.

[0011] The micro-negative pressure dehumidification component is located at the tail end of the cylinder and communicates with the inside of the cylinder. It is used to continuously extract moisture during the drying process, maintain a micro-negative pressure environment inside the cylinder, thereby reducing the water evaporation temperature, improving dehydration efficiency, and reducing the loss of heat-sensitive components.

[0012] The upper and lower inner walls of the cylinder are both fixedly equipped with impact tooth plate assemblies, forming a synergistic material dispersing system of non-powered self-excited vibration and mechanical impact shaking.

[0013] Furthermore, the elastic floating installation mechanism includes two sets of symmetrically installed mounting discs, a first drive motor, a second drive motor, and a rotation disc. The two sets of mounting discs are symmetrically installed at both ends of the inner cavity of the cylinder. A first drive motor is provided on the outer side of one side of the mounting disc, and the end face of the mounting disc is respectively provided with an embedded inner groove and an annular groove. Multiple sets of guide rods are distributed along the circumferential direction inside the annular groove, and a sliding frame is adapted to slide in the middle section of the guide rod. The second drive motor is located in the inner groove.

[0014] Furthermore, the central shaft end of the indexing disk is coaxially and fixedly connected to the output shaft of the second drive motor, and multiple sets of hook-shaped slots are evenly opened along the circumferential direction inside the indexing disk body. A double-shaft sleeve is laterally sleeved inside each set of slots. One end of the double-shaft sleeve is fixedly connected to the slide frame, and the other end is laterally sleeved to the rotor tube bundle. A reset spring is provided between the end of the rotor tube bundle and the inner cavity sidewall of the double-shaft sleeve to realize automatic reset after the rotor tube bundle fluctuates.

[0015] Furthermore, on the other side, the mounting plate has multiple sets of inclined grooves radiating outwards from the rotor tube bundle end along the circumferential direction. The multiple sets of inclined grooves extend outwards from the center of the mounting plate as the origin. The rotor tube bundle end is embedded and slids inside the corresponding inclined groove. A push-pull cylinder is provided between the mounting plate away from the rotor tube bundle end and the inner cavity sidewall corresponding to the cylinder.

[0016] Furthermore, the irregularly shaped staggered composite lifting plate adopts a combination structure of alternating long and short sections and staggered angles, and it is divided into upright and inclined lifting plates, which are evenly and differentially arranged on the outer edge of the tube bundle. The irregularly shaped staggered composite lifting plate has elastic deformation capability. When rotating and lifting the material, it undergoes slight deformation. When the material is spilled, the stress is released and regular shaking is formed, which can effectively break up the clump of fiber material.

[0017] Furthermore, the impact toothed plate assembly includes a static toothed plate, a double-groove shift frame, a slide rod, a reset elastic element, and a strip brush. The static toothed plate is fixedly embedded in the top of the inner cavity of the cylinder, and a rectangular toothed groove is opened at the bottom of the static toothed plate. A double-groove shift frame is horizontally sleeved inside each set of rectangular toothed grooves. The slide rod is fixedly installed at the top center of the double-groove shift frame, and the top end of the slide rod is adapted to slide and connect to the slide groove on the inner wall of the top of the rectangular toothed groove.

[0018] Furthermore, the top two ends of the double-slot moving frame are symmetrically provided with slot structures, and are slidably sleeved on the frame on both sides of the rectangular toothed groove through the slots. A reset spring is connected between the inner wall of the slot and the side wall of the rectangular toothed groove. A through slot is provided at the center of the bottom of the double-slot moving frame, and a strip brush is embedded in the inner wall on both sides of the through slot.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention overcomes the shortcomings of traditional tube bundle dryers, which have fixed positions and simple material turning, by setting up an elastic floating installation mechanism and a composite lifting plate with irregular staggered arrangement to coordinate material dispersing system. On the one hand, the composite lifting plate is divided into two structures: upright and inclined, which can realize the up-and-down turning and axial pushing of materials respectively. The differentiated arrangement structure can effectively break up the agglomerates of soybean dietary fiber. At the same time, the lifting plate has micro-elastic deformation characteristics. During the lifting and spreading process, it can generate regular shaking through deformation and stress release, which can prevent the fiber material from agglomerating and accumulating from the source.

[0021] On the other hand, the flexible floating installation mechanism can drive the rotor tube bundle to achieve adaptive adjustment of radial position and controllable axial fluctuation. Combined with the periodic extension and retraction of the push-pull cylinder and the elastic reset effect of the reset spring, the lifting plate continuously generates micro-vibration, dynamically loosening the sticky fiber material. At the same time, the tube bundle distribution can be adjusted in real time according to the material filling state in the cylinder, eliminating the drying blind spots and local material accumulation problems existing in traditional equipment, ensuring the loose state of the material throughout the process, and laying the foundation for uniform dehydration.

[0022] 2. This invention also constructs a collaborative system of non-powered self-excited vibration and mechanical impact material shaking by setting an impact toothed plate assembly on the inner wall of the cylinder. No additional driving power is required. The equipment can be triggered to vibrate by relying on the rotation of the rotor tube bundle and the periodic disturbance of the lifting plate. This actively peels off the soybean dietary fiber material adhering to the lifting plate and the inner wall of the cylinder, reducing the problems of material sticking to the wall, carbonization, accumulation and deterioration. Moreover, the assembly has an adaptive self-cleaning function. For the lifting plates with two different shapes, upright and inclined, two cleaning modes can be achieved by the cooperation of double-groove frame shifting, reset elastic element and strip brush, respectively, to achieve gap friction cleaning and adhesion scraping cleaning. This comprehensively cleans the residual material on the surface of the lifting plate, solves the problem of easy adhesion and blockage of fiber materials, and continuously ensures the stability of the turning and heat exchange structure.

[0033] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 - Figure 3 As shown, a tube bundle dryer for dehydrating soybean dietary fiber based on vibration feeding includes a closed horizontal cylinder 1, a spiral conveyor 2, multiple sets of rotor tube bundles 3, a steam heat exchange assembly 4, and a micro negative pressure dehumidification assembly 5; the spiral conveyor 2 includes a conveying pipe 21 and a matching spiral conveying rod 22. The conveying pipe 21 is integrally fixedly installed on one side of the front end of the cylinder 1, and the spiral conveying rod 22 is provided inside the conveying pipe 21.

[0035] Multiple sets of rotor tube bundles 3 are arranged along the transverse circumference inside the cylinder 1, and the rotor tube bundles 3 are provided with an elastic floating installation mechanism 6 on the outside. The rotor tube bundles 3 are installed inside the cylinder 1 through the elastic floating installation mechanism 6, which can realize radial adjustment and axial controllable fluctuation. Irregular staggered composite lifting plates 7 are welded and fixed on the outside of the rotor tube bundles 3.

[0036] The steam heat exchange component 4 is located at the center of the top surface of the cylinder 1 and at the end of the cylinder 1 away from the conveying pipe 21. The steam heat exchange component 4 is used to provide a stable heat source to the inside of the cylinder 1.

[0037] The micro-negative pressure dehumidification component 5 is located at the tail end of the cylinder 1 and is connected to the inside of the cylinder 1. It is used to continuously extract moisture during the drying process, maintain a micro-negative pressure environment inside the cylinder, thereby reducing the water evaporation temperature, improving the dehydration efficiency and reducing the loss of heat-sensitive components.

[0038] Impact toothed plate assemblies 8 are fixedly installed on both the upper and lower inner walls of the cylinder 1, forming a material unloading system that combines non-powered self-excited vibration with mechanical impact shaking.

[0039] The specific workflow is as follows: After the material enters the cylinder 1 through the conveying pipe 21, it moves slowly along the axial direction under the push of the screw conveyor 22; at the same time, the rotor tube bundle 3 rotates continuously under the drive mechanism, and the irregular staggered composite lifting plates 7 on its outer side continuously lift and scatter the material, so that the material can fully contact the high temperature tube wall and be heated evenly; due to the existence of the elastic floating installation mechanism 6, the rotor tube bundle 3 can adaptively adjust its radial position according to the material filling state during operation and generate slight axial fluctuations, effectively preventing material accumulation and local overheating;

[0040] During the rotation of the rotor tube bundle 3, the impact tooth plate assembly 8 is periodically disturbed, triggering a self-excited vibration without power. This vibration, combined with the lifting plate action, enables the active peeling and loosening of the adhering material. Meanwhile, the steam heat exchange assembly 4 continuously supplies saturated steam, which is efficiently transferred through the inner cavity of the rotor tube bundle 3. At the same time, the micro-negative pressure dehumidification assembly 5 simultaneously extracts and removes the moisture generated by evaporation, ensuring a stable negative pressure environment inside the cylinder. This significantly improves the moisture migration rate and prevents the degradation of heat-sensitive functional components in soybean dietary fiber due to prolonged exposure to high temperatures.

[0041] Example 2: Please refer to Figure 3 - Figure 5 As shown, the elastic floating installation mechanism 6 includes two sets of symmetrically installed installation discs 61, a first drive motor 62, a second drive motor 63, and a rotation disc 64. The two sets of installation discs 61 are symmetrically installed at both ends of the inner cavity of the cylinder 1. A first drive motor 62 is provided on the outer side of one side of the installation disc 61, and the end face of the installation disc 61 is respectively provided with an embedded inner groove and an annular groove. Multiple sets of guide rods 65 are distributed along the circumferential direction inside the annular groove, and a sliding frame 66 is adapted to slide in the middle section of the guide rod 65. The second drive motor 63 is located in the inner groove.

[0042] The central shaft of the indexing disk 64 is coaxially and fixedly connected to the output shaft of the second drive motor 63. The inside of the indexing disk 64 is evenly provided with multiple sets of hook-shaped slots along the circumferential direction. Each set of slots is laterally fitted with a double-shaft sleeve 67. One end of the double-shaft sleeve 67 is fixedly connected to the slide frame 66, and the other end is laterally fitted to the rotor tube bundle 3. A reset spring is provided between the end of the rotor tube bundle 3 and the inner cavity side wall of the double-shaft sleeve 67 to realize the automatic reset of the rotor tube bundle 3 after fluctuation.

[0043] On the other side, multiple sets of inclined slots are radially opened along the circumferential direction at the end of the rotor tube bundle 3 corresponding to the mounting plate 61. The multiple sets of inclined slots extend outward from the center of the mounting plate 61 as the origin. The end of the rotor tube bundle 3 is embedded and slid in the corresponding inclined slot. A push-pull cylinder 68 is jointly provided between the end of the mounting plate 61 away from the rotor tube bundle 3 and the inner cavity sidewall corresponding to the cylinder 1.

[0044] The irregular staggered composite lifting plate 7 adopts a combination structure of alternating long and short sections and staggered angles. It is divided into upright and inclined lifting plates, which are evenly and differentially arranged on the outer edge of the tube bundle. The irregular staggered composite lifting plate 7 has elastic deformation capability. When rotating and lifting the material, it undergoes slight deformation. When the material is spilled, the stress is released and regular shaking is formed, which can effectively break up the clump of fiber material.

[0045] The specific steps for drying materials include:

[0046] (a) The normal drying process is as follows: the material enters the cylinder 1 through the screw conveyor 2, and the drive motor 62 is started to drive the mounting plate 61 on the corresponding side and the multiple sets of rotor tube bundles 3 to move synchronously in the circumferential direction. Then, the material is turned over by the irregularly shaped composite lifting plates 7 with alternating lengths and angles. The upright lifting plates turn the material up and down, while the inclined shovels are used to move and transfer the material, so that the material is slowly pushed along the axis in the cylinder 1 while being fully exposed to the hot air environment, so as to achieve uniform heating and efficient dehydration.

[0047] (ii) When adjusting the position of the tube bundle distributed on the circular shaft: drive motor 62 is turned off and drive motor 63 is started, which drives the rotary disk 64 to rotate. Under the action of the hook-type slot internal structure, the double shaft sleeve 67 is pushed up or down. While the traction slide frame 66 slides along the outside of the guide rod 65, the rotor tube bundle 3 also moves. The rotor tube bundle 3 slides and shifts in the inclined slot, thereby changing its distribution position on the cross-section of the cylinder. At this time, the lifting plate layout forms a new disturbance mode due to the change in the position of the tube bundle, which can specifically improve the problem of local material accumulation or drying blind area.

[0048] (iii) In addition, during the drying process, the mounting plate 61 on the other side generates axial reciprocating micro-movement under the periodic extension and retraction of the push-pull cylinder 68, which in turn drives the rotor tube bundle 3 to move laterally. Combined with the synergistic effect of the double-shaft sleeve 67 and the reset spring, the rotor tube bundle 3 is subjected to radial elastic fluctuation, thereby forcing the irregular staggered composite lifting plate 7 to generate slight vibration, further enhancing the disintegration effect on soybean dietary fiber agglomerates and reducing fiber.

[0049] Example 3: Please refer to Figure 6 - Figure 7 As shown, the impact toothed plate assembly 8 includes a static toothed plate 81, a double-groove shift frame 82, a slide rod 83, a reset spring element, and a strip brush 84. The static toothed plate 81 is fixedly embedded in the top of the inner cavity of the cylinder 1, and a rectangular toothed groove is opened at the bottom of the static toothed plate 81. A double-groove shift frame 82 is horizontally sleeved inside each set of rectangular toothed grooves. The slide rod 83 is fixedly installed at the top center of the double-groove shift frame 82, and the top of the slide rod 83 is adapted to slide and connect to the slide groove on the inner wall of the top of the rectangular toothed groove. The top two ends of the double-groove shift frame 82 are symmetrically provided with slot structures, and are slidably sleeved on the frame on both sides of the rectangular toothed groove through the slots. A reset spring element is connected between the inner wall of the slot and the side wall of the rectangular toothed groove. A through groove is opened at the bottom center of the double-groove shift frame 82, and strip brushes 84 are respectively embedded in the inner walls on both sides of the through groove.

[0050] During the rotation of the rotor tube bundle 3, the irregularly shaped staggered composite lifting plates 7 on its outer edge periodically impact the interior of the double-slot moving frame 82. When the vertical lifting plate moves and inserts into the slot, the strip brushes 84 on both sides of the vertical lifting plate are released and directly perform friction cleaning. When the inclined lifting plate passes through the corresponding slot, the inclined lifting plate pushes the double-slot moving frame 82 to move laterally along the rectangular toothed groove, compressing the reset elastic element, so that the strip brushes 84 on both sides of the slot are in close contact with the lifting plate surface for scraping cleaning. When the lifting plate is disengaged, the reset elastic element drives the double-slot moving frame 82 back to its initial position, preparing for the next cleaning action. This structure achieves adaptive cleaning of lifting plates of different shapes through the synergistic effect of friction cleaning and elastic reset, effectively preventing material adhesion and blockage, and further improving the uniformity of material discharge and heat exchange efficiency.

[0051] Working principle: In use, the wet soybean dietary fiber material is first fed into the sealed horizontal cylinder 1 through the conveying pipe 21. Under the push of the screw conveyor 22, the material moves slowly along the axial direction. At the same time, the drive motor 62 is started, which drives the mounting plate 61 and the rotor tube bundle 3 to rotate synchronously. The irregular staggered composite lifting plate 7 then turns and throws the material in multiple dimensions, so that it is evenly distributed and fully contacts the high temperature tube wall. The steam heat exchange component 4 continuously introduces saturated steam into the inner cavity of the rotor tube bundle 3. The heat is efficiently conducted to the surface of the material through the tube wall, which promotes the rapid evaporation of moisture. The micro negative pressure dehumidification component 5 operates synchronously, forming a stable negative pressure environment at the tail end of the cylinder, reducing the boiling point of water, accelerating the discharge of moisture, and effectively preventing heat-sensitive components from deteriorating due to high temperature retention.

[0052] During the drying process, the elastic floating mounting mechanism 6 automatically adjusts the radial position of the rotor tube bundle 3 according to the material filling density, and works in conjunction with the axial micro-movement generated by the push-pull cylinder 68 to make the lifting plate vibrate at high frequency and continuously dissipate fiber agglomerates. At the same time, the rotating lifting plate periodically impacts the double-groove moving frame 82 in the toothed plate assembly 8, triggering the strip brush 84 to dynamically scrape and clean the surface of the lifting plate, preventing material adhesion and accumulation, and ensuring that the heat exchange surface is always in a high-efficiency working state, ultimately achieving low-temperature, high-efficiency, and uniform dehydration of soybean dietary fiber.

[0053] Obviously, many modifications and variations can be made based on the content of this specification. These embodiments have been selected and specifically described in this specification to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
