Description

Technical Field

[0001] This invention relates to the field of gellan gum technology, specifically to a continuous gellan gum production equipment. Background Technology

[0002] Gellan gum, also known as gellan gum or gellan gum, is a microbial polysaccharide produced by *Pseudomonas elutulata*. Its main components are glucose, glucuronic acid, and rhamnose in a 2:1:1 ratio. It is a linear polysaccharide composed of four monosaccharides as repeating structural units. Gellan gum is produced by the pure culture fermentation of carbohydrates (such as glucose and sucrose) by microorganisms such as *Pseudomonas elutulata* or *Sphingomyelinus*. The final product is refined through processes including fermentation, pH adjustment, clarification, precipitation, pressing, drying, and milling.

[0003] Chinese invention patent CN212820166U discloses a pulverizer for gellan gum production that facilitates feeding and has a drying function. The pulverizer includes a pulverizing chamber and an inclined plate. An insulation layer is connected to the outer wall of the pulverizing chamber, and the outer wall of the pulverizer is connected to the outer wall of the insulation layer. A heating pipe is connected to the middle of the inner side of the insulation layer, and an inclined plate is connected to the top of the insulation layer. An anti-slip base is connected to the bottom of the outer wall of the pulverizer. A discharge port is opened in the middle of the bottom of the outer wall of the pulverizer, and an air chamber is connected to the bottom of the inner side of the outer wall of the pulverizer. An air jet is connected to one side of the upper end of the air chamber. This pulverizer for gellan gum production, which facilitates feeding and has a drying function, is equipped with an insulation layer between the pulverizing chamber and the outer wall of the pulverizer. This insulation layer can comprehensively insulate the raw materials inside the entire equipment, keeping the interior of the equipment dry. Furthermore, a heating pipe is installed inside the insulation layer, which can be used to dry the raw materials.

[0004] Furthermore, since existing fermenters use anchor-type agitators for stirring, the viscosity of the fermentation broth increases with the formation and accumulation of gellan gum, easily leading to dead zones in the stirring. This means that only the fermentation broth around the agitator blades rotates with the blades, while the kinetic energy, velocity, and gas content of the fermentation broth decrease further away from the blades. The fermentation broth at the tank wall is almost static, which inhibits cell metabolism, shifts sugar metabolism pathways, and drastically reduces gellan gum production rate and sugar conversion rate. In addition, during the filter press process, uneven feeding speed, inconsistent filter cake thickness, or poor filter plate sealing can all cause fluctuations in filtration pressure. Moreover, the filter cake itself has a certain degree of stickiness and easily adheres to the inside of the filter press, making it difficult for the operator to handle and affecting preparation efficiency. Therefore, the gellan gum production pulverizer disclosed in Chinese invention patent CN212820166U, which is easy to feed and has a drying function, cannot fully stir the gellan gum and cannot guarantee the stability of the filter press pressure.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the present invention provides a continuous production equipment for gellan gum, which has the following beneficial effects:

[0022] 1. The liquid is pushed into the interior of the mixing tank by the stirring paddle, which reduces the volume of liquid inside the mixing tank and thus reduces the range of movement between liquid solutes. The stirring frame stirs the liquid inside the mixing tank, increasing the collision frequency between the liquid solutes inside the mixing tank and the stirring frame, preventing the liquid solutes from agglomerating, increasing the contact frequency between different liquid solutes, and thus improving the uniformity of the fermentation broth mixing.

[0023] 2. The liquid in the middle of the fermentation tank is pushed by the stirring plate and flows intermittently between the stirring plate and the fermentation tank to the side of the stirring plate near the slot, which increases the contact frequency between the liquid in the middle of the fermentation tank and the liquid at both ends, and improves the flowability of the liquid inside the fermentation tank.

[0024] 3. The filter cake is filtered by pressing the liquid into the tank through the pressure plate, ensuring the consistency of the filter cake size after filtration. The filter cake is automatically separated by the second contact rod, avoiding the problem of the filter cake being too sticky and difficult to handle. The arc-shaped sliding groove drives the second filter plate to repeatedly squeeze and separate from the first filter plate, thereby increasing the continuity of the filter cake separation and filtration process and improving the filtration efficiency of the filter cake preparation.

A groove 2049 is provided on one side. A contact rod 20410 is fixedly connected to the side of the rotating block 2048 away from the rotating plate 2045. The contact rod 20410 and the groove 2049 are on the same horizontal plane. A fixing rod 20411 is rotatably connected to the outer wall of the baffle 2044. A gear 20412 is fixedly connected to the outer wall of the fixing rod 20411. The gear 20412 meshes with the annular toothed plate 2046. A fixing plate 20413 is fixedly connected to the end of the fixing rod 20411 away from the baffle 2044. The size of the groove 2049 is adapted to the size of the fixing plate 20413. Several grooves 20414 are arranged in a ring array on the outer wall of the fixing plate 20413. The size of the grooves 20414 is adapted to the size of the contact rod 20410.

[0044] Furthermore, the stirring assembly 205 includes a stirring trough plate 2061 symmetrically threaded to the outer wall of the threaded rod 2047. Stirring frames 2062 are fixedly connected in a ring array on the inner wall of the stirring trough plate 2061. A guide plate 2063 is rotatably connected to the side wall of the stirring trough plate 2061. Six stirring paddles 2065 are fixedly connected in a ring array on the inner wall of the guide plate 2063. Six slots 2064 are arranged in a ring array on the outer wall of the guide plate 2063. Elastic telescopic rods 2066 are symmetrically fixedly connected to the outer wall of 61. A baffle 2067 is fixedly connected between the two elastic telescopic rods 2066. Several filter holes are opened on the side of the stirring tank plate 2061 near the baffle 2067. Several blocking rods 2068 are arranged in a ring array on the side wall of the baffle 2067. The number of blocking rods 2068 corresponds one-to-one with the number of filter holes. A scraper 2069 is slidably connected inside the slot 2064. The rotating plate 2045 is fixedly connected to the scraper 2069.

[0045] It should be noted that the scraper 2069 abuts against the inner wall of the fermentation tank 202, and the stirring plate 2061 is internally engaged with the guide plate 2063, which allows the stirring plate 2061 to rotate while driving the guide plate 2063 to rotate.

[0046] Furthermore, the reciprocating assembly 304 includes a feed port 3051 fixedly connected to the top of the filter press 301.

The size of the ball rod 3059 is adapted to the size of the arc-shaped groove 3055.

[0047] It should be noted that the ball rod 3059 is symmetrically arranged at the upper and lower ends of the arc-shaped slide 3055, so that during the rotation of the arc-shaped slide 3055, the second contact rod 3071 and the first filter plate 3072 will move closer and separate.

[0048] Furthermore, the filter press assembly 306 includes a second abutment rod 3071 symmetrically fixedly connected to the outer wall of the third fixed plate 3056, a first filter press plate 3072 fixedly connected to the end of the second connecting plate 3058 away from the third fixed plate 3056, a guide hose 3052 communicating with the interior of the first filter press plate 3072, a second filter press plate 3074 fixedly connected to the end of the first connecting plate 3057 away from the third fixed plate 3056, the second filter press plate 3074 slidably connected to the interior of the first filter press plate 3072, a loading groove 3073 symmetrically opened on the first filter press plate 3072, and a pressure plate 3075 symmetrically fixedly connected to the inner wall of the second filter press plate 3074, with the pressure plate 3075 corresponding to the loading groove 3073 one by one.

[0049] The following describes the working process and principle of the above embodiments:

[0050] The initial state is as follows: the elastic telescopic rod 2066 is in an unextended state, the ball rod 3059 fixedly connected to the outer wall of the connecting plate 2 3058 is in the arc-shaped groove 3055 near the top of the fixed plate 3056, and the ball rod 3059 fixedly connected to the outer wall of the connecting plate 1 3057 is in the arc-shaped groove 3055 away from the top of the fixed plate 3056.

[0051] The work steps are as follows:

[0052] First, the operator connects the feeding device to the feeding port 2041, so that the material to be fermented falls into the fermentation cylinder 202 through the feeding port 2041. Then, the feeding port 2041 controls the rotating block 2048 to rotate, so that the rotating block 2048 drives the threaded rod 2047 to rotate on the inner wall of the baffle 2044, so that the threaded rod 2047 drives the stirring plate 2061 to move away from the guide plate 2063, so that the stirring plate 2061 drives the guide plate 2063 to move synchronously.

[0053] During the rotation of the rotating block 2048, the rotating block 2048 causes the first groove 2049 and the first abutment rod 20410 to rotate synchronously. This causes the first abutment rod 20410 to rotate into the interior of the second groove 20414, and causes the first fixing plate 20413 to move into the interior of the first groove 2049. Consequently, the first abutment rod 20410 abuts against the inner wall of the second groove 20414, causing the second groove 20414 to drive the first fixing plate 20413 and the first fixing rod 20411 to rotate synchronously. The intermittent rotation of the baffle 2044 causes the fixed rod 20411 to drive the gear 20412 to rotate synchronously, which in turn drives the meshing annular toothed plate 2046 to rotate synchronously. The annular toothed plate 2046 then drives the rotating plate 2045 to rotate at the connection between the connecting rod 102 and the fermentation cylinder 202. A sealing strip on the rotating plate 2045 seals the fermentation cylinder 202. Subsequently, the rotating plate 2045 drives the scraper 2069. The fermentation tank 202 rotates synchronously inside, causing the scraper 2069 to scrape off the liquid adhering to the inner wall of the fermentation tank 202. This causes the scraper 2069 to drive the guide plate 2063 to rotate on the threaded rod 2047, which in turn causes the guide plate 2063 to drive the stirring frame 2062 to rotate synchronously. Simultaneously, driven by the stirring plate 2061, the guide plate 2063 moves away from the rotating plate 2045, causing the stirring plate 2061 to drive the elastic telescopic rod 2... 066 and baffle 2067 move synchronously, so that baffle 2067 is always in contact with stirring plate 2061 under the action of liquid resistance, and the stirring plate 2061 pushes the liquid in the middle of fermentation tank 202 to flow through the intermittent flow between stirring plate 2061 and fermentation tank 202 to the side of stirring plate 2061 near the slot 2064, which increases the contact frequency between the middle of fermentation tank 202 and the liquid at both ends, and improves the flowability of liquid inside fermentation tank 202.

[0054] Subsequently, controller 2042 controls rotating block 2048 to begin rotating in the reverse direction, causing rotating block 2048 to drive fixed plate 20413 to rotate intermittently in the reverse direction. Fixed plate 20413, through gear 20412, drives rotating plate 2045 and annular toothed plate 2046 to rotate in the reverse direction synchronously. Rotating plate 2045 drives scraper 2069 to move synchronously. Rotating block 2048, through threaded rod 2047, drives stirring tank plate 2061 to move closer to annular toothed plate 2046. Stirring tank plate 2061 drives guide... The flow channel plate 2063 moves synchronously, causing the flow guide plate 2063 to rotate synchronously in the opposite direction via the scraper 2069. Under the resistance of the stirring plate 2061, it moves towards the side closer to the rotating plate 2045. During the reverse rotation of the flow guide plate 2063, it also causes the stirring paddle 2065 to rotate synchronously in the opposite direction. This causes the stirring paddle 2065 to contact the liquid at an oblique angle, guiding the liquid into the interior of the flow guide plate 2063 and the stirring plate 2061, and allowing it to enter the flow guide plate. The liquid in the mixing tank 2063 and mixing plate 2061 begins to rotate, causing it to frequently collide with the mixing frame 2062 during its rotation inside the mixing tank 2061. Subsequently, the rotating liquid impacts the blocking rod 2068, causing the baffle 2067 to move away from the mixing tank 2061. This causes the baffle 2067 to extend the elastic telescopic rod 2066 away from the mixing tank 2061, ultimately allowing the stirred liquid to enter the middle of the fermentation tank 202 through the filter holes in the mixing tank 2061, and then... The next stirring is carried out, and the liquid is pushed into the interior of the stirring tank plate 2061 by the stirring paddle 2065, which reduces the volume of liquid inside the stirring tank plate 2061, thereby reducing the range of movement between liquid solutes. The stirring frame 2062 stirs the liquid inside the stirring tank plate 2061, increasing the collision frequency between the liquid solute inside the stirring tank plate 2061 and the stirring frame 2062, preventing the liquid solute from agglomerating, increasing the contact frequency between different liquid solutes, and thus improving the uniformity of the fermentation broth mixing.

[0055] After liquid fermentation is complete, controller 2042 controls the second fixed plate 3054 to rotate on the second fixed rod 3053, causing the second fixed plate 3054 to reciprocate horizontally by contacting the ball rod 3059 via the arc-shaped sliding groove 3055. This, in turn, causes the second connecting plate 3058 to move away from the second fixed plate 3054, and the arc-shaped sliding groove 3055 to move closer to the second fixed plate 3054. This, in turn, causes the first connecting plate 3057 to move closer to the second fixed plate 3054, thereby causing the first filter plate 3057 to move closer to the second fixed plate 3054. 72 drives the two contact rods 3071 to move closer and squeeze each other. When the pressure plate 3075 enters the interior of the loading tank 3073 and seals it, the controller 2042 controls the extraction port 3051 to draw liquid from the fermentation tank 202, allowing the liquid to enter the interior of the filter plate 3072 through the guide hose 3052, filling the loading tank 3073. Then, the pressure plate 3075 continues to move into the loading tank 3073, squeezing and dehydrating the liquid inside. After filtration is completed, controller 2042 controls fixed plate 3054 to move connecting plate 3058 and connecting plate 3057 away from fixed plate 3054 via ball rod 3059. This causes connecting plate 3057 to separate filter plate 3074 from filter plate 3072, which is driven by connecting plate 3058. Subsequently, contact rod 3071 moves to the inside of loading tank 3073 and contacts the filter cake left after filtration, causing the filter cake to move into loading tank 3073. The external movement of 73 causes the filter cake to fall onto the filter plate 303. It then enters the loading tank 3073 through the pressure plate 3075 to filter the cooling liquid, ensuring the consistency of the filter cake size after filtration. The filter cake is automatically separated by the contact rod 3071, avoiding the problem of excessively sticky filter cake that is difficult to handle. The arc-shaped sliding groove 3055 drives the filter plate 3074 to repeatedly squeeze and separate from the filter plate 3072, thereby increasing the continuity of the filter cake separation and filtration process and improving the filtration efficiency of the filter cake preparation.
