Description

Technical Field

[0001] The utility model relates to the technical field of welan gum fermentation, in particular to a high-viscosity microbial polysaccharide welan gum fermentation device. Background Art

[0002] Welan gum is a microbial polysaccharide synthesized by certain alcaligenes bacteria and Sphingomonas. Welan gum is a typical pseudoplastic fluid with excellent thickening, suspending, and emulsifying properties, particularly resistance to high temperatures, acids, alkalis, and hydrochloric acid. Welan gum aqueous solutions are heat-stable, with their viscosity remaining essentially unchanged at temperatures up to 149°C. Its temperature resistance limit is 20-30°C higher than that of xanthan gum. Welan gum is also stable to acids and alkalis, with its viscosity remaining largely unaffected within the pH range of 2-13. It also exhibits high salt stability, making it suitable for use as a thickener, suspending agent, emulsifier, stabilizer, and water-retaining agent in various industrial and agricultural applications.

[0003] The production materials of welan gum are highly viscous when mixed together and stirred. In order to ensure the stability of stirring, the general fermentation stirring device is fixed together with the stirring head and the fermentation barrel. This connection method is difficult to clean after the production of welan gum. It is not convenient to clean the stirring head and the barrel, and it is easy to cause residues in the fermentation barrel, which causes certain inconveniences during use.

[0004] Therefore, we proposed a high-viscosity microbial polysaccharide welan gum fermentation device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a high-viscosity microbial polysaccharide welan gum fermentation device to solve the problem that the production materials of welan gum proposed in the above background technology are more viscous when mixed together and stirred. In order to ensure the stability of stirring, the general fermentation stirring device fixes the stirring head and the fermentation barrel together during use. This connection method is difficult to clean after the production of welan gum, and is not convenient for cleaning the stirring head and the barrel, which easily causes residues in the fermentation barrel, causing certain inconveniences during use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-viscosity microbial polysaccharide welan gum fermentation device, comprising a fermentation tank body and support legs fixedly installed at the four corners of the lower end of the fermentation tank body, a movable cover movably installed at the upper end of the fermentation tank body, a discharge port provided at the lower end of the fermentation tank body, a movable plug rotatably installed in the discharge port, a mounting plate fixedly installed at the upper end of the movable cover, a motor fixedly installed on the mounting plate, a feed pipe fixedly installed on the movable cover, a plurality of blocks fixedly installed at equal distances on the side of the movable cover, a plurality of slots equidistantly provided on the inner wall of the upper end of the fermentation tank body, and a plurality of the blocks are slidably connected in the plurality of the slots respectively.

[0007] Preferably, a rotating rod is fixedly mounted on the output end of the motor, the rotating rod is rotationally connected to the movable cover, and a connecting rod is fixedly mounted on one end of the rotating rod.

[0008] Preferably, two stirring rods 1 and two stirring rods 2 are fixedly mounted on the side walls of the connecting rod, and the two stirring rods 1 have the same curvature as the inner side wall of the lower end of the fermentation tank body.

[0009] Preferably, fixed rods are fixedly installed on both side walls of the lower end of the connecting rod, and a movable rod is rotatably installed between the fixed rod and the second stirring rod.

[0010] Preferably, stirring blades are fixedly provided at equal intervals on the outer circumference of the movable rod, and the outer curvature of the stirring blades is the same as the curvature of the inner side wall of the lower end of the fermentation tank body.

[0011] Preferably, oblique convex teeth are fixedly installed at equal intervals on the inner wall of the fermentation tank body, and a helical gear is fixedly installed on one end of the movable rod, and the helical gear is meshed with the oblique convex teeth.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Since the raw materials for preparing welan gum have a high viscosity during fermentation, the stirring head needs to be disassembled and cleaned after use. When using the device to prepare welan gum, the various required raw materials can be added to the fermentation tank body through the feed pipe, and then the motor is started to drive the stirring structure through its output end to mix and stir the raw materials in the fermentation tank body. After a long period of fermentation, the movable cover can be directly lifted up. At this time, the movable cover can be taken out together with the motor and the stirring structure extending into the fermentation tank body. After the stirring and fermentation is completed, the stirring structure can be completely removed through the movable cover for cleaning, which is convenient for cleaning the fermented material with strong viscosity and facilitating subsequent fermentation operations.

[0014] 2. When using the device to stir and ferment the Welan gum raw materials, first add the raw materials one by one into the fermentation tank body through the feed pipe, start the motor, and the rotating rod at the output end of the motor rotates. When the rotating rod rotates, it drives the connecting rod to rotate. When the connecting rod rotates, it drives the stirring rod 1 and stirring rod 2 on the side wall to rotate inside the fermentation tank body to stir the raw materials. The stirring rod 1 fits against the inner wall of the fermentation tank body and stirs the raw materials on the inner wall of the fermentation tank body. When the stirring rod 2 rotates, it drives the bevel gear to rotate along the bevel convex teeth. At this time, the bevel gear drives the movable rod to rotate. When the movable rod rotates, it drives the stirring blades on its side wall to rotate. The stirring direction of the stirring blade is different from that of the stirring rod 1, which can mix the raw materials more fully. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 - Figure 3A high-viscosity microbial polysaccharide welan gum fermentation device comprises a fermentation tank body 1 and supporting legs 2 fixedly installed at the four corners of the lower end of the fermentation tank body 1, a movable cover 3 is movably installed at the upper end of the fermentation tank body 1, a discharge port 13 is provided at the lower end of the fermentation tank body 1, a movable plug 14 is rotatably installed in the discharge port 13, a mounting plate 4 is fixedly installed at the upper end of the movable cover 3, a motor 5 is fixedly installed on the mounting plate 4, a feed pipe 31 is fixedly installed on the movable cover 3, a plurality of blocks 32 are fixedly installed at equal distances on the side of the movable cover 3, a plurality of slots 11 are equidistantly opened on the inner wall of the upper end of the fermentation tank body 1, and the plurality of blocks 32 are slidably connected in the plurality of slots 11 respectively.

[0022] In this embodiment: Since the raw materials for preparing welan gum have a high viscosity during fermentation, the stirring head needs to be disassembled and cleaned after use. When using the device to prepare welan gum, various required raw materials can be added to the fermentation tank body 1 through the feed pipe 31, and then the motor 5 is started to drive the stirring structure through its output end to mix and stir the raw materials in the fermentation tank body 1. After a long period of fermentation, the movable cover 3 can be directly lifted upward. At this time, the movable cover 3 can be taken out together with the motor 5 and the stirring structure extending into the fermentation tank body 1. After the stirring and fermentation is completed, the stirring structure can be completely taken out through the movable cover 3 for cleaning, which is convenient for cleaning the fermented material with strong viscosity and facilitating subsequent fermentation operations.

[0023] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 2 - Figure 4 The output end of the motor 5 is fixedly mounted with a rotating rod 51, which is rotationally connected to the movable cover 3. One end of the rotating rod 51 is fixedly mounted with a connecting rod 6, which can be driven to rotate by the motor 5.

[0024] Two stirring rods 1 61 and two stirring rods 2 62 are fixedly installed on the side walls of the connecting rod 6. The two stirring rods 1 61 have the same curvature as the inner wall of the lower end of the fermentation tank body 1. The stirring rod 1 61 fits well with the inner wall of the lower end of the fermentation tank body 1 to better stir and turn over the fermented material and stir it evenly.

[0025] A fixed rod 63 is fixedly installed on both side walls of the lower end of the connecting rod 6 , and a movable rod 64 is installed between the fixed rod 63 and the second stirring rod 62 for common rotation. The movable rod 64 rotates between the fixed rod 63 and the second stirring rod 62 .

[0026] Stirring blades 65 are fixedly arranged at equal intervals on the outer circumference of the movable rod 64. The outer curvature of the stirring blades 65 is the same as the curvature of the inner wall of the lower end of the fermentation tank body 1. The stirring blades 65 are used to turn over the fermented material at the lower end of the fermentation tank body 1, further improving the degree of stirring of the fermented material.

[0027] The inner wall of the fermentation tank body 1 is fixedly installed with oblique convex teeth 12 at equal intervals, and one end of the movable rod 64 is fixedly installed with a bevel gear 66, which meshes with the oblique convex teeth 12. The setting of the oblique convex teeth 12 can cooperate with the bevel gear 66 to drive the movable rod 64 to rotate.

[0028] In this embodiment: when using the device to stir and ferment the Weilan gum raw material, the raw materials are first added one by one into the fermentation tank body 1 through the feed pipe 31, and the motor 5 is started. At this time, the rotating rod 51 at the output end of the motor 5 rotates, and the rotating rod 51 drives the connecting rod 6 to rotate when it rotates. When the connecting rod 6 rotates, it drives the stirring rod 1 61 and the stirring rod 2 62 on the side wall to rotate inside the fermentation tank body 1 to stir the raw materials. The stirring rod 1 61 fits into the inner wall of the fermentation tank body 1 and stirs the raw materials on the inner wall of the fermentation tank body 1. When the stirring rod 2 62 rotates, it drives the bevel gear 66 to rotate along the bevel convex tooth 12. At this time, the bevel gear 66 drives the movable rod 64 to rotate. When the movable rod 64 rotates, it drives the stirring blade 65 on its side wall to rotate. The stirring direction of the stirring blade 65 is different from that of the stirring rod 1 61, and the raw materials can be stirred and mixed more fully.
