Description

Technical Field

[0001] This utility model relates to the field of fermentation devices, and in particular to a fermentation device that can be backwashed. Background Technology

[0002] Fermentation equipment is specialized equipment used for microbial fermentation production, providing a suitable environment for microbial growth and metabolism. During operation, the culture medium and inoculum are first injected into the device. A temperature control system regulates the temperature, an aeration system controls the oxygen content, a stirring system ensures uniform mixing of the materials, and a pH adjustment module maintains a stable acid-base balance. Most devices are equipped with sealed chambers to prevent contamination and material leakage; some also include monitoring sensors to provide real-time feedback on fermentation parameters. It is widely used in food, pharmaceutical, and environmental protection fields, ensuring efficient microbial conversion of raw materials and achieving stable production of the target product through precise control of fermentation conditions.

[0003] The backwashable fermentation device is a specialized piece of equipment that adds a backwashing system to a conventional fermentation device. After fermentation is complete, there is no need to disassemble the device. First, the residual material inside is discharged, and then high-pressure cleaning water or special cleaning solution is injected back into the chamber through the device's built-in backwash pipeline. The water flow will impact the surface of components such as the chamber wall, stirring paddle, and sensors, washing away the attached culture medium residue and bacterial dirt.

[0004] After existing fermentation equipment completes the fermentation process, culture medium residues, bacterial fragments, and secretions easily remain on the inner wall of the chamber, the stirring blades, and the surface of the temperature / pH sensor. These residues are highly sticky, and if not thoroughly removed, they will breed other bacteria. During the next fermentation, these other bacteria will compete with the target strain for nutrients, leading to a decrease in product purity, a sharp reduction in yield, and even the scrapping of the entire batch of material. Furthermore, the residues will dry and harden over time, forming stubborn dirt that not only affects the heat and mass transfer efficiency of the equipment but may also corrode the inner wall of the equipment, shortening its service life. Therefore, a fermentation equipment with backwashing capability is proposed to solve the above problems. Utility Model Content

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.

[0019] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a backwashable fermentation device, comprising a fermenter body 1, with a backwashing structure 2 inside the fermenter body 1; the backwashing structure 2 includes a body 21, a fixing plate 24 threadedly connected to the side of the body 21, and a fixing bolt 25 threadedly connected to the inside of the fixing plate 24; the inside of the body 21 has a threaded groove, and the size of the threaded groove inside the body 21 matches that of the fixing bolt 25. This design allows the fixing plate 24 to be threadedly fixed to the side of the body 21 by the fixing bolt 25; a motor 26 is fixedly connected to the side of the fixing plate 24; a main rotating rod 27 is rotatably connected inside the body 21; a connecting rod 28 is fixedly connected to the side of the main rotating rod 27; a guide plate 29 is fixedly connected to the side of the connecting rod 28; the guide plate 29 has multiple inclined guide grooves inside, and the inclination angle of each guide groove is set to 30 degrees. The tilted design allows the guide plate 29 to guide a large amount of water to the inner wall of the body 21 through the guide channel. The side of the main rotating rod 27 is fixedly connected to the inner connecting plate 210, and the inside of the body 21 is fixedly connected to the outer connecting plate 211. The side of the outer connecting plate 211 is slidably connected to the pulley 212, and the side of the pulley 212 is slidably connected to the roller 213. The side of the roller 213 is slidably connected to the rotating block 214, and the side of the rotating block 214 is fixedly connected to the cleaning block 215. The inside of the rotating block 214 is fixedly connected to the guide block 216. The inside of the guide block 216 is provided with multiple tilted guide channels, and the tilt angle of each guide channel is set to 15 degrees. The 15-degree tilted guide channel design allows the guide block 216 to transmit water to the surface of the cleaning block 215 of other guide blocks 216 and the inner wall of the body 21 and rinse them with water. The inside of the body 21 is provided with an anti-residue structure 3.

[0020] Reference Figure 3 - Figure 4An inlet 22 is fixedly connected to one side of the interior of the body 21, and an outlet 23 is fixedly connected to the other side of the interior of the body 21. The anti-residue structure 3 includes a protrusion 31 and a connecting plate 32. There are four protrusions 31, and the four protrusions 31 are fixedly connected to the four walls inside the body 21. The design of the four protrusions 31 increases the number of impacts between the impact block 36 and the protrusions 31. A rotating wheel 33 is rotatably connected inside the connecting plate 32. A rotating groove is opened inside the connecting plate 32, and the size of the rotating groove inside the connecting plate 32 matches that of the rotating wheel 33. This design allows the rotating wheel 33 to rotate inside the connecting plate 32. A connecting plate 34 is fixedly connected to the side of the rotating wheel 33 away from the connecting plate 32. A spring piece 35 is fixedly connected to the side of the connecting plate 34. One side of the spring piece 35 is fixedly connected to the side of the connecting plate 32, and the other side is fixedly connected to the side of the connecting plate 34. An impact block 36 is fixedly connected to the side of the connecting plate 34.

[0021] Working principle: When rinsing the fermenter body 1 after use, the external water source is first connected to the water inlet 22, and the motor 26 is turned on at the same time. The motor 26 turns the main rotating rod 27, and the water source is guided by the guide plate 29 connected by the side connecting rod 28. The rotation of the main rotating rod 27 will drive the inner connecting plate 210 to rotate. The rotation of the inner connecting plate 210 causes the pulley 212 to slide on the side of the outer connecting plate 211, and the roller 213 on the side drives the rotating block 214 to rotate inside the body 21. The rotation of the rotating block 214 causes the cleaning block 215 to clean the inside of the body 21. In conjunction with the guide groove inside the guide block 216, the inside of the body 21 is effectively agitated and cleaned, thereby avoiding the retention of highly sticky residues such as culture medium residue, bacterial fragments and secretions inside the fermenter body 1.

[0022] When the main rotating rod 27 rotates to backwash and clean the fermenter body 1, the rotation of the main rotating rod 27 causes the connecting plate 32 to rotate inside the machine body 21, and causes the top impact block 36 to collide with the protrusion 31 and generate vibration. Through the impact of the impact block 36 and the protrusion 31, the connecting plate 34 drives the impact block 36 to rotate on the side of the connecting plate 32 via the rotating wheel 33, and at the same time pulls the side spring 35 to tighten the spring 35. As the main rotating rod 27 continues to rotate, the impact block 36 will lose the compression with the protrusion 31, and its spring 35 will pop out and return the connecting plate 34 and the impact block 36 to their positions to prepare for the next impact. The design of multiple protrusions 31 and impact blocks 36 inside the machine body 21 increases the impact frequency of the impact blocks 36 and protrusions 31, thereby achieving the effect of multiple vibrations inside the machine body 21, which, together with the water flow and the cleaning block 215, thoroughly cleans the residual residue and finally discharges it from the outlet 23 with the water flow.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
