Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, specifically to a fermentation tank for polysaccharide extraction that facilitates material discharge. Background Technology

[0002] As is well known, a fermenter for polysaccharide extraction is a bioreactor specifically designed for the microbial fermentation production of polysaccharides, and for controlling and optimizing the fermentation process. It provides a suitable growth environment for microorganisms, enabling them to efficiently synthesize polysaccharides, while facilitating subsequent polysaccharide extraction and purification. It is widely used in the food, pharmaceutical, and chemical industries.

[0003] However, most fermentation tanks for polysaccharide extraction on the market currently have the problem of inconvenient material discharge. Because polysaccharide materials are sticky, they easily adhere to the inner wall of the machine, the surface of the stirring components and other parts, forming residue accumulation. This makes it difficult for the material to be discharged smoothly when using traditional gravity discharge or simple stirring-assisted discharge, which not only increases the discharge time, but also causes material waste and increases the difficulty of cleaning the equipment. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a fermenter for polysaccharide extraction that facilitates material discharge.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a fermenter for polysaccharide extraction that facilitates discharge, comprising a body, a cover plate, a first bolt, and a hydraulic pushing mechanism. The bottom of the body is provided with a support base, and several support bases are provided. The cover plate is connected to the body via the first bolt. The hydraulic pushing mechanism includes a fixing ring, a second bolt, a support plate, a hydraulic component, and a sealing block. The fixing ring is fitted onto the outer wall of the body and is connected via the second bolt. One end of the support plate is connected to the fixing ring, one end of the hydraulic component is connected to the support plate, and the other end of the hydraulic component is connected to one end of the sealing block. A sealing ring is provided on the outer wall of the sealing block. A stirring component is provided on the top of the cover plate, and the output end of the stirring component is located inside the body.

[0006] To improve the connection effect, the present invention is improved by providing a plurality of first bolts, which are symmetrically arranged, and providing a plurality of second bolts, which are symmetrically arranged.

[0007] To facilitate observation of the internal condition of the machine, the present invention is improved by providing an observation window on the front of the machine body, which is embedded in the front of the machine body.

[0008] To facilitate operation of the equipment, the present invention is improved by providing a controller on the top of the support plate, and the controller is electrically connected to the hydraulic component.

[0009] To achieve an anti-slip effect, the present invention is improved by providing an anti-slip layer at the bottom of the support base, and the anti-slip layer is fixedly connected to the bottom of the support base.

[0010] To improve the anti-slip effect, the present invention is improved by using a rubber material for the anti-slip layer.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a fermenter for polysaccharide extraction that facilitates material discharge, and has the following beneficial effects: This fermenter for polysaccharide extraction, designed for easy discharge, features a hydraulic push mechanism to enhance discharge convenience. When discharge is required, first unscrew the second bolt to separate the fixing ring from the machine body, then remove the first bolt and take off the cover plate. Subsequently, re-fix the fixing ring to the outer wall of the machine body using the second bolt, allowing the sealing block of the hydraulic push mechanism to precisely extend into the inner cavity. After activating the hydraulic components, the sealing block descends along the inner wall, its inclined contact surface, combined with the conical bottom structure of the machine body, pushing the material to the bottom. Simultaneously, the inner wall of the machine body and contact parts are coated with Teflon, utilizing its low surface energy to reduce material adhesion and avoid the material residue problem found in traditional structures, allowing the fermentation liquid to be smoothly discharged through the bottom outlet. This device can reduce the discharge time of high-viscosity polysaccharides (such as xanthan gum, viscosity 1200 cP) from 40 minutes to 25 minutes, reduce the residue rate from 15% to below 1%, and reduce cleaning time by 50%, significantly improving production efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 A fermenter for polysaccharide extraction with easy discharge includes a body 1, a cover plate 2, a first bolt 3, and a hydraulic pushing mechanism 7. The bottom of the body 1 is provided with a support base 5, and there are several support bases 5. The cover plate 2 is connected to the body 1 by the first bolt 3. The hydraulic pushing mechanism 7 includes a fixing ring 8, a second bolt 9, a support plate 10, a hydraulic component 11, and a sealing block 12. The fixing ring 8 is sleeved on the outer wall of the body 1 and is connected by the second bolt 9. One end of the support plate 10 is connected to the fixing ring 8. One end of the hydraulic component 11 is connected to the support plate 10, and the other end of the hydraulic component 11 is connected to one end of the sealing block 12. The outer wall of the sealing block 12 is provided with a sealing ring. The top of the cover plate 2 is provided with a stirring component 4, and the output end of the stirring component 4 is located inside the body 1.

[0015] Working principle: Place the equipment in the designated location and achieve stable support through several support bases 5. The rubber anti-slip layer at the bottom of the support bases 5 can enhance the friction between the equipment and the ground. Then connect the equipment to the external mains power to complete the power supply connection. Connect the feeding, discharging, and ventilation pipes on the equipment to the external supporting equipment. The machine body 1 is a conventional polysaccharide extraction fermentation tank, which integrates components such as stirring assembly 4, heating mechanism, temperature adjustment mechanism, and pH adjustment mechanism (the specific structure refers to the existing technology). After the material is poured into the machine body 1, start the stirring assembly 4 on the top of the cover plate 2 to stir the material evenly. At the same time, the various control systems maintain the parameters such as temperature, pH, and dissolved oxygen required for fermentation to complete the fermentation process. After fermentation, the receiving device is placed below the discharge port at the bottom of the machine body 1. The operator first holds the support plate 10 and uses a screwdriver to unscrew the second bolt 9 to separate the fixing ring 8 from the machine body 1. Then, the first bolt 3 is removed to separate the cover plate 2 from the machine body 1. The fixing ring 8 is then fixed to the outer wall of the machine body 1 again using the second bolt 9. At this time, the hydraulic component 11 drives the sealing block 12 to extend into the machine body 1. The controller 13 at the top of the support plate 10 is activated, and the hydraulic component 11 drives the sealing block 12 to move downward. It is precisely matched with the inner wall of the machine body 1 (tolerance ≤ 0.1mm). The outer wall sealing ring fills the gap to prevent leakage. The side of the sealing block 12 that contacts the material is designed with an inclined angle. Combined with the conical bottom structure of the machine body 1, the material is pushed to the bottom. At the same time, the inner wall of the machine body 1 and the contact parts are coated with Teflon to reduce the adhesion of the material and ensure that the material flows out smoothly through the bottom discharge component. After discharge, use external flushing equipment to clean the inside of the tank, and wait for the equipment to return to normal. Figure 1 The initial state shown is sufficient; The stirring assembly 4 on top of the cover plate 2 adopts a three-bladed turbine stirrer with an adjustable speed range of 100-300 rpm; The hydraulic component 11 mentioned in the text is a common technology on the market, and its specific structure (such as hydraulic cylinder, hydraulic pump, etc.) will not be described in detail here.

[0016] To improve the stability of the connection structure, in this embodiment, the first bolt 3 and the second bolt 9 are arranged in a symmetrical manner. The first bolt 3 is evenly distributed along the connection interface between the cover plate 2 and the body 1, and local stress concentration is avoided by symmetrical force. The second bolt 9 is symmetrically arranged around the fixing ring 8 to ensure the connection strength between the hydraulic push mechanism 7 and the outer wall of the body 1. This design can make the load between the components evenly transmitted and prevent loosening or deformation caused by unilateral force.

[0017] To facilitate real-time observation of the fermentation status inside the machine body 1, this embodiment embeds an observation window 6 on the front of the machine body 1. The observation window 6 is made of transparent tempered glass, which has an impact resistance 3-5 times that of ordinary glass after high-temperature quenching treatment. It can resist accidental collisions during the fermentation process and maintain high light transmittance, ensuring that staff can clearly see the stirring and fermentation of materials inside the tank through the window.

[0018] To improve the ease of operation of the equipment, this embodiment integrates a controller 13 on the top of the support plate 10. The controller 13 is electrically connected to the hydraulic component 11 via a cable. Operators can adjust the pushing pressure and speed of the hydraulic component 11 in real time through the controller 13 panel to achieve precise control of the descent process of the sealing block 12. This design avoids the cumbersome traditional manual operation and effectively improves the automation level and operating efficiency of the discharge process.

[0019] To address the issue of slippage when the support base 5 comes into contact with a smooth surface, this embodiment includes a fixed anti-slip layer at the bottom of the support base 5. This anti-slip layer is made of highly elastic rubber and features a densely packed texture on its surface that increases the coefficient of friction with the ground. This ensures stable support even in humid environments, effectively preventing the equipment from shifting due to vibration or external forces and improving the stability of the fermenter during operation.

[0020] To further enhance the anti-slip effect, the anti-slip layer at the bottom of the support base 5 in this embodiment is made of rubber. This rubber material has high elasticity and wear resistance. Its micro-rough structure can effectively increase the friction with the ground. Even in wet or slippery ground environments, it can significantly improve the anti-slip performance of the equipment, ensuring that the fermentation tank remains stable during operation and avoiding positional displacement due to slippage.

[0021] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
