Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and in particular to a high-efficiency dryer for viscous fermented materials. Background Technology

[0002] Dryers are primarily used for drying viscous fermented materials in the food, pharmaceutical, and bioengineering industries. The device typically includes a heated cylinder with an internal stirring mechanism. By introducing a heat medium such as steam or hot water into the cylinder's jacket or interior, combined with the continuous tumbling of the stirring blades, the material is heated evenly, achieving rapid evaporation of moisture. Its design aims to handle high-viscosity, easily agglomerated fermentation products that traditional drying equipment struggles with, employing specific structural optimizations to achieve better drying results and operational stability.

[0003] However, traditional fermentation material drying equipment currently has significant shortcomings in practical applications. Because the drying cylinder is typically a single, enclosed structure, the built-in stirring rod must have a certain safety gap with the inner wall of the cylinder to ensure normal rotation and avoid collision. When processing highly viscous or bulky fermentation materials, the material in this gap area is difficult for the stirring rod to effectively reach, easily creating dead zones and material adhering to the walls. This results in uneven mixing, hindered heat transfer, and ultimately low drying efficiency and increased energy consumption. A more prominent problem is that this single-piece cylinder structure and built-in stirring system are extremely difficult to disassemble. After use, viscous materials easily clump together on the surface of the stirring rod and in the nooks and crannies of the cylinder, causing severe cleaning difficulties. This not only affects the purity of subsequent materials but may also pose hygiene and safety hazards due to the spoilage of residual materials. 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.

[0011] In a preferred embodiment of the high-efficiency dryer for viscous fermented materials according to the present invention, the stirring assembly further includes a fixed cylinder fixedly installed inside the connecting plate. A first servo motor is fixedly installed at the bottom of the fixed cylinder. The output end of the first servo motor is connected to a first rotating shaft via a coupling. The bottom end of the first rotating shaft penetrates the bottom wall of the fixed cylinder and extends to the right side of the inner cylinder, and is fixedly connected to a stirring plate. The connecting ring is fixedly installed on the left outer wall of the fixed cylinder.

[0012] In a preferred embodiment of the high-efficiency dryer for viscous fermented materials described in this invention, the rotating assembly includes a second servo motor fixedly installed at the center of the top wall of the upper cavity.

[0017] The beneficial effects of this invention are: 1. This invention, through a unique "overall rotation of the inner cylinder + localized fixed-point stirring" composite motion mode, completely solves the problems of stirring dead zones and uneven drying in traditional drying equipment. Specifically, the second servo motor drives the entire inner cylinder to rotate slowly inside the outer cylinder through the insertion and cooperation of the cross lever and the fixed column, allowing the material in each area of ​​the inner cylinder to periodically move to the working area of ​​the stirring plate on the right side; simultaneously, the first servo motor independently drives the stirring plate to perform high-speed local stirring in this area, forcefully turning over and breaking up the material that has moved there. This synergistic effect allows viscous materials to achieve both overall circulation and sufficient stirring in specific areas within the cylinder, effectively preventing material adhesion and caking, ensuring that every part of the material can be evenly contacted by the hot airflow, thereby significantly improving drying efficiency and ensuring the uniformity of drying quality.

[0018] 2. This invention, through the combined design of a liftable stirring mechanism and a movable material cylinder frame, achieves rapid separation of the drying component and the material holding component, fundamentally solving the persistent problem of difficult cleaning in traditional integrated equipment. After drying is complete, the lifting assembly drives the stirring plate, cross lever, and other components upwards, completely separating them from the inner cylinder area. The operator only needs to lift the outer cylinder upwards with the lifting rod to disengage the retaining ring, and then easily pull the entire movable support frame out from the loading and unloading opening using the casters, achieving complete separation of the material cylinder from the main body. At this time, all parts in contact with the material, such as the inner and outer walls of the inner cylinder, the stirring plate, and the baffle vents, are exposed to the open space, allowing the operator to thoroughly clean them from all angles, avoiding hygiene and safety hazards caused by material residue. This is particularly suitable for industries with stringent cleanliness requirements, such as food and pharmaceuticals, significantly reducing the difficulty of equipment maintenance and operating costs.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] Referring to the figures, the present invention provides a high-efficiency dryer for viscous fermentation materials, the overall structure of which includes an outer shell 100 serving as a supporting base. The outer shell 100 is generally box-shaped, with a sized loading and unloading opening 101 in the middle region of its left side wall, allowing the cylindrical assembly containing the material to enter and exit. To rationally arrange the various functional components, the internal space of the outer shell 100 is divided into multiple chambers: specifically, an upper cavity 102 is located above the loading and unloading opening 101, a lower cavity 103 is located below the loading and unloading opening 101, and a side cavity 104 is located on the right side of the interior of the outer shell 100, communicating with the upper cavity 102. These chambers are interconnected but have different functions, collectively forming the mounting base of the entire machine.

[0025] To achieve efficient thermal drying, an airflow dryer 200 is fixedly installed inside the lower cavity 103. This airflow dryer 200 is a key component providing the hot air drying medium, and an air outlet 201 is located on the left side of its top. To precisely guide the hot airflow to the material area, a guide plate 105 is connected to the output end of the air outlet 201. This guide plate 105 is fixedly installed in the upper left position of the lower cavity 103, directly below the loading / unloading opening 101. Its function is to guide the hot airflow generated by the airflow dryer 200 upwards, preparing for subsequent drying operations.

[0026] To achieve uniform agitation and efficient drying of materials, a stirring mechanism 300 is installed inside both the upper cavity 102 and the side cavity 104. This stirring mechanism 300 is an integrated functional component, specifically including a lifting component 301 for lifting, a stirring component 302 for local stirring, and a rotating component 303 for driving the overall rotation.

[0027] The lifting assembly 301 is mainly located within the side cavity 104. Its structure includes an electric hydraulic cylinder 301b fixedly installed at the bottom of the side cavity 104, which serves as the lifting power source. An extendable telescopic rod 301c is movably connected inside the cylinder. A lifting plate 301d is fixedly connected to the output end of the telescopic rod 301c. This lifting plate 301d can move up and down along the side cavity 104 under the drive of the hydraulic cylinder. To the left of the lifting plate 301d, a horizontally extending connecting plate 301a is fixedly connected. The left end of the connecting plate 301a passes through the partition between the side cavity 104 and the upper cavity 102 and extends into the upper cavity 102. To ensure the smooth and guiding movement of the connecting plate 301a, a vertical lifting groove 106 is provided between the upper cavity 102 and the side cavity 104. The middle part of the connecting plate 301a is slidably connected in the lifting groove 106, so that the up and down movement of the lifting plate 301d can be accurately transmitted to the connecting plate 301a and its connected components.

[0028] The left end of the connecting plate 301a is connected to the stirring assembly 302 via a transmission connection. The stirring assembly 302 specifically includes a fixed cylinder 302b fixedly installed inside the connecting plate 301a, which rises and falls together with the connecting plate 301a. A first servo motor 302c is fixedly installed at the bottom inside the fixed cylinder 302b, providing independent power for localized stirring. The output end of the first servo motor 302c is connected to a first rotating shaft 302d via a coupling. The bottom end of the first rotating shaft 302d penetrates the inner bottom wall of the fixed cylinder 302b and extends downwards, with a stirring plate 302e fixedly connected to its end. When the first servo motor 302c starts, the first rotating shaft 302d drives the stirring plate 302e to rotate, thereby providing strong localized stirring of the material in the right-side area of ​​the inner cylinder 402, effectively preventing sticky materials from adhering in this area.

[0029] To achieve the rotation of the entire inner cylinder 402, a rotating assembly 303 is located at the center of the upper cavity 102. Its structure includes a second servo motor 303a fixedly installed at the center of the top wall inside the upper cavity 102, which serves as the power source for the cylinder's rotation. The output end of the second servo motor 303a is connected to a second rotating shaft 303b via a coupling, and the second rotating shaft 303b extends vertically downwards. A telescopic cavity 303c is formed inside the bottom end of the second rotating shaft 303b, and symmetrical through-holes 303d are formed on the left and right sides of the telescopic cavity 303c. A rotating rod 303e is slidably connected inside the telescopic cavity 303c, and the rotating rod 303e can slide up and down within the cavity. Symmetrically mounted on the left and right sides of the rotating rod 303e are two actuating rods 303f that are adapted to the through-holes 303d, and these two actuating rods 303f respectively pass through the two through-holes 303d and extend outwards. The bottom end of the rotating rod 303e extends further into the interior of the inner cylinder 402 and is fixedly connected to a cross-shaped locking rod 303g, which is used for insertion and transmission with the structure at the bottom of the inner cylinder.

[0030] A connecting ring 302a is fixedly installed on the outer left side of the fixed cylinder 302b in the stirring assembly 302. The connecting ring 302a is sleeved on the outside of the second rotating shaft 303b. An annular groove 302a1 is formed on the inner side of the connecting ring 302a. The two actuating rods 303f that pass through the limiting groove 303d have their outer ends extending into the annular groove 302a1 and slidingly connected to the inner wall of the connecting ring 302a. This ingenious structural design allows the actuating rods 303f to rotate with the second rotating shaft 303b within the annular groove 302a1, and also to move synchronously up and down when the lifting assembly 301 moves the connecting ring 302a up and down, being abutted by the upper and lower inner walls of the annular groove 302a1, thus achieving a composite transmission of power and motion.

[0031] To facilitate the loading and unloading of materials, this invention also includes a movable support frame 400. The core component of this frame is an outer cylinder 401 movably installed inside the loading / unloading opening 101. This outer cylinder 401 can be pushed into or pulled out of the outer shell 100 as a whole through the loading / unloading opening 101. An inner cylinder 402 is rotatably connected inside the outer cylinder 401, and the inner cylinder 402 is used to directly hold the viscous fermentation material. Both the outer cylinder 401 and the inner cylinder 402 are designed as bucket-shaped structures with openings at both ends, i.e., they are vertically connected. This design facilitates the flow of hot air through the material layer from top to bottom and also allows water to pass through during washing. A baffle 403 is fixedly installed at the bottom of the inner cylinder 402. This baffle 403 rotates with the inner cylinder 402, supporting the material and guiding the airflow. The baffle 403 has multiple evenly distributed exhaust holes 403a inside, used to evenly disperse the hot airflow from the lower air guide plate 105 into the inner cylinder 402.

[0032] On the front and rear sides of the outer cylinder 401, symmetrical mounting frames 404 are arranged, serving as connecting bridges for the machine frame. Movable support assemblies 405 are installed at the bottom of the two mounting frames 404 to support the entire machine frame and enable movement. The movable support assembly 405 specifically includes a support frame 405a fixedly installed at the bottom of the two mounting frames 404, providing stable support for the entire cylinder. Casters 405b are installed at the bottom of the support frame 405a, facilitating flexible movement of the machine frame on the ground. Furthermore, lifting rods 405c are symmetrically installed on the front and rear sides above the support frame 405a, and these two lifting rods 405c are bent. Correspondingly, each of the two mounting frames 404 has a mounting groove 404a inside, and the bent ends of the two lifting rods 405c are movably mounted within the two mounting grooves 404a, with both ends of the two lifting rods 405c fixedly connected to the outer wall of the outer cylinder 401. With this structure, the outer cylinder 401 is mounted above the mounting frame 404 and the support frame 405a via two lifting rods 405c. When the cylinder needs to be moved, the operator can hold the lifting rods 405c and apply force to easily push the entire frame via the casters 405b.

[0033] To enable rapid connection and separation between the inner cylinder 402 and the rotary drive mechanism, a fixing post 406 is fixedly installed at the center of the top of the baffle 403. The upper surface of the fixing post 406 has a cross-shaped slot 406a. The cross-shaped locking rod 303g at the bottom of the rotary assembly 303 can be inserted into the cross-shaped slot 406a to achieve circumferential fixation. This allows the torque of the second servo motor 303a to be transmitted to the fixing post 406 through the cross-shaped locking rod 303g, thereby driving the inner cylinder 402 to rotate smoothly inside the outer cylinder 401.

[0034] To achieve airflow sealing and positioning during drying operations, a circular groove 107 is provided on the outer side of the air guide plate 105, and a retaining ring 407 that matches the circular groove 107 is fixedly installed at the bottom of the outer cylinder 401. When the movable support frame 400 is pushed into the loading and unloading opening 101 to the working position, the outer cylinder 401 is precisely engaged above the circular groove 107 by the retaining ring 407, forming a positioning, while ensuring that the hot airflow output from the air guide plate 105 can be concentrated and enter the inner cylinder 402 through the exhaust hole 403a of the baffle 403. At this time, an appropriate gap is reserved between the upper surface of the outer cylinder 401 and the top wall of the loading and unloading opening 101 to avoid movement interference.

[0035] The function of this invention will be further explained below in conjunction with its working process: Before the drying operation, the operator first puts the sticky fermented material to be dried into the inner cylinder 402. Then, by pushing the lifting rod 405c, the mobile support frame 400 is pushed towards the loading and unloading opening 101 of the outer shell 100 with the help of the casters 405b. When the retaining ring 407 at the bottom of the outer cylinder 401 is aligned and falls into the circular groove 107 on the outside of the air guide plate 105, the frame reaches the preset working position and completes precise positioning.

[0036] When the drying operation starts, the airflow dryer 200, the first servo motor 302c, and the second servo motor 303a are started simultaneously. The hot airflow generated by the airflow dryer 200 enters the air guide plate 105 through the air outlet 201. Guided by the air guide plate 105, the airflow flows upward and evenly enters the inner cylinder 402 through the densely distributed exhaust holes 403a on the baffle 403, thermally drying the fermenting material in the tumbling process. At the same time, the first servo motor 302c drives the stirring plate 302e to rotate continuously through the first rotating shaft 302d, providing localized and strong stirring of the material in the right area of ​​the inner cylinder 402. This action can effectively break the adhesion tendency of the material in this area, prevent the material from caking, and thus significantly improve the local heat exchange efficiency.

[0037] While the stirring plate 302e is working, the second servo motor 303a is also operating synchronously. Its power is transmitted through the second rotating shaft 303b. Since the actuating rod 303f on the second rotating shaft 303b is inserted into the annular groove 302a1 of the connecting ring 302a, and the actuating rod 303f abuts against the side wall of the limiting through groove 303d, the rotation of the second rotating shaft 303b will drive the rotating rod 303e, the cross clamping rod 303g, and the fixed cylinder 302b that is clamped to it to rotate as a whole through the actuating rod 303f, thereby driving the baffle 403 and the inner cylinder 402 to rotate slowly and smoothly inside the outer cylinder 401.

[0038] The rotation of the inner cylinder 402 causes all the material inside to undergo a circular motion within the cylinder. As a result, material originally located on the left, front, or rear sides of the inner cylinder 402, away from the stirring plate 302e, gradually moves to the working area of ​​the stirring plate 302e on the right side as the cylinder rotates, receiving forced mechanical stirring. This combined working mode of "overall rotation of the inner cylinder + localized fixed-point stirring" completely eliminates the problem of dead zones caused by gaps between the stirring rod and the cylinder wall in traditional drying equipment. This ensures that every part of the material inside the cylinder receives uniform agitation and heat exchange, significantly improving drying efficiency and ensuring the uniformity of material drying.

[0039] When the drying operation is completed and the equipment needs to be cleaned or the material replaced, the lifting assembly 301 is activated. Specifically, the electric hydraulic cylinder 301b drives the telescopic rod 301c to retract upwards, causing the lifting plate 301d and the connecting plate 301a to move upwards. The rise of the connecting plate 301a causes the entire stirring assembly 302 to move upwards. At this time, the connecting ring 302a in the stirring assembly 302 rises accordingly. Since the two ends of the actuating rod 303f are slidably connected in the annular groove 302a1, and the upper and lower ends of the actuating rod 303f abut against the inner top wall and inner bottom wall of the connecting ring 302a respectively, the rise of the connecting ring 302a will cause the actuating rod 303f to move vertically upwards together. Guided by the limiting through groove 303d, the actuating rod 303f drives the rotating rod 303e and the cross lever 303g to slide upwards in the telescopic cavity 303c. When the lever 303f moves to the top of the limiting groove 303d, the rotating rod 303e and the cross lever 303g are completely retracted into the telescopic cavity 303c. At this time, the stirring plate 302e, the first rotating shaft 302d, the cross lever 303g and the rotating rod 303e in the stirring assembly 302 have all been completely removed from the outer space of the inner cylinder 402 and have completely separated from the inner cylinder 402.

[0040] After completing the above lifting and lowering actions, the operator can proceed to remove the material cylinder assembly. Simply lift the outer cylinder 401 upwards gently using the lifting rod 405c, causing the retaining ring 407 at the bottom of the outer cylinder 401 to disengage from the circular retaining groove 107, thus releasing the positioning. Subsequently, by pulling the lifting rod 405c, with the auxiliary support of the support frame 405a and the casters 405b, the entire mobile support frame 400 (including the outer cylinder 401 and the inner cylinder 402) can be easily pulled completely out of the loading and unloading opening 101 of the outer casing 100, achieving complete separation of the material cylinder from the main body.

[0041] At this point, with both the inner cylinder 402 and the outer cylinder 401 removed, and the stirring components (such as the stirring plate 302e and the cross lever 303g) exposed, operators can easily and thoroughly clean these components. Even hard-to-reach areas such as the inner wall of the inner cylinder 402, the inner cavity of the outer cylinder 401, the gaps in the stirring plate 302e, and the vent 403a of the baffle 403 can be rinsed and wiped without obstruction. This completely separable structural design fundamentally solves the problems of difficult cleaning and unsanitary areas in traditional integrated drying equipment, greatly reducing maintenance difficulty and ensuring the hygiene requirements of food and pharmaceutical production.

[0042] It is important to note that the actuating lever 303f plays a crucial role throughout the entire operation. It functions as both a drive component, with its outer end slidingly engaging with the annular groove 302a1 of the connecting ring 302a and its inner end abutting against the side wall of the limiting groove 303d, thus transmitting torque as the second rotating shaft 303b rotates; and a transmission component, where the actuating lever 303f slides up and down within the limiting groove 303d via the thrust applied by the inner top or bottom wall of the annular groove 302a1 when the connecting ring 302a is moved up and down by the lifting assembly 301. This ingenious structural design decouples and combines rotary and linear motion, ensuring the coordinated and reliable operation of the entire machine.

[0043] In summary, this invention, by integrating a movable material cylinder frame, a liftable stirring mechanism, a composite rotary drive system, and a precise airflow guiding structure, not only achieves efficient and uniform drying of viscous fermentation materials, but also completely solves the problem of equipment cleaning, demonstrating significant practicality and advancement.

[0044] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative.
