Description

Technical Field

[0001] The utility model relates to the technical field of inoculation tanks, in particular to a feeding microbial liquid inoculation tank. Background Art

[0002] In the process of microbial fermentation production, an inoculation tank is required for inoculation of bacteria. There are various inoculation methods for microbial fermentation. The most commonly used method is to directly inject bacteria into the fermentation container. In order for the inoculation tank to meet the cleanliness requirements of inoculation and avoid the introduction of miscellaneous bacteria, the inoculation tank must be cleaned and sterilized. Generally, steam is introduced to sterilize the inoculation tank.

[0003] The existing steam sterilization method for inoculation tanks is to directly introduce high-temperature steam through the nozzle or air outlet pipe at the top of the inoculation tank. In order to prevent the fermented material from blocking the nozzle, the nozzle is difficult to be evenly distributed in the tank, which makes it difficult for the steam to transfer the high temperature to the bottom of the tank, and the sterilization effect is poor. In addition, the nozzle or air outlet pipe is directly exposed in the tank, which is also easy to leave or hide the bacteria, forming a dead corner, which is difficult to clean and affects the next bacterial inoculation and fermentation work.

[0026] In this embodiment, Figure 1 As shown, a feed microorganism liquid inoculation tank includes a fermentation tank 1, which is composed of an outer tank 2 and an inner tank 3. A clamping cavity 4 is arranged between the outer tank 2 and the inner tank 3. A telescopic component 5 is arranged on the outer tank 2. A sealing block 6 is slidably installed on the through hole of the inner tank 3. The telescopic component 5 drives the sealing block 6 to seal or move away from the through hole. An air distribution pipe 7 is arranged in the clamping cavity 4. A nozzle 8 is arranged on the air distribution pipe 7, and the nozzle 8 is directly opposite to the through hole.

[0027] When sterilization is required, the telescopic component 5 with the sealing block 6 is away from the through hole, and the multiple nozzles 8 on the air distribution pipe 7 introduce steam into the tank for sterilization. The steam is evenly and fully distributed, which improves the sterilization effect. During inoculation and fermentation, the nozzle 8 is in a non-working state, and the telescopic component 5 with the sealing block 6 seals the through hole and will not contact the strain, thus reducing the dead corners where the strain remains and reducing the impact on the next inoculation and fermentation work.

[0028] Preferably, the inner tank 3 is a ceramic tank.

[0029] There are many nozzles on the air distribution pipe 7, which provide steam in the clamping cavity 4 to heat the inner tank 3, and the ceramic tank has a good thermal conductivity.

[0030] Preferably, a feed pipe 9 is provided on the fermentation tank 1, and the feed pipe 9 is provided with an interlayer, and the interlayer is connected with the gas distribution pipe 7 and an external steam source.

[0031] The high temperature of steam is used to sterilize and disinfect the residual bacteria in the feeding pipe 9.

[0032] Preferably, a sealing gasket is provided between the sealing block 6 and the inner tank 3 .

[0033] The sealing gasket can improve the sealing between the sealing block 6 and the inner tank 3.

[0034] Preferably, both the outer tank 2 and the inner tank 3 are provided with condensed water discharge outlets.

[0035] Preferably, a limiting protrusion is provided on the sealing block 6 .

[0036] Prevent the cylinder 11 from malfunctioning and prevent the sealing block 6 from escaping from the through hole. Example

[0037] Based on the above embodiments, this embodiment Figure 2 As shown, the telescopic assembly 5 includes a fixed plate 10, a cylinder 11, a connecting plate 12, a slide rod 13 and a spring 14. The fixed plate 10 is installed on the outside of the outer tank 2, the cylinder 11 is installed on the fixed plate 10, the connecting plate 12 is vertically arranged and connected to the output end of the cylinder 11, the spring 14 tightens the fixed plate 10 and the connecting plate 12 respectively, the slide rod 13 is slidably installed on the outer tank 2, and the two ends of the slide rod 13 are respectively connected to the connecting plate 12 and the closed block 6.

[0038] When the cylinder 11 extends, the connecting plate 12 moves the slide bar 13 back and forth, thereby controlling the sealing block 6 to seal or stay away from the through hole. The spring 14 can ensure that the sealing block 6 seals the through hole when the cylinder 11 is not working.

[0039] Preferably, the extension direction of the cylinder 11 gradually moves away from the gas outlet direction of the nozzle 8 .

[0040] The cylinder 11 is tilted so that it can make a deviation movement when pushing the sealing block 6 away from the through hole on the inner tank 3, so as to fully expose the nozzle 8 and ensure that the steam enters the inner tank 3 better and more completely.
