Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of biological fermentation, and in particular relates to an aseptic sampling system for a biological fermentation tank with flushing and sewage discharge functions. Background Art
[0002] Microbial fermentation products are produced in batches in a fermentation tank, which generally takes about 3-10 days. During the fermentation process, the physical and chemical parameters of the fermentation liquid in the tank are tested several times a day according to the product process control needs. The acquisition of physical and chemical parameters often requires the fermentation liquid to be taken out of the tank and then tested offline. Therefore, it is very important to ensure that the fermentation liquid in the fermentation tank is not contaminated during frequent sampling operations and to clean the residues in the environment in time after sampling.
[0003] The sampling valve and pipeline need to be sterilized before sampling. If the design is unreasonable, the sampling pipeline will not be sterilized thoroughly, causing the sampling pipeline to be contaminated and affecting the fermentation liquid in the fermentation tank. At the same time, in order to ensure the representativeness of the sampling, some fermentation liquid in the sampling pipeline from the sampling valve near the tank to the side of the tank is often released before sampling. These fermentation liquids will remain in the sampling sewage funnel. If they are not cleaned in time or the amount of water used for cleaning is insufficient, the fermentation liquid in the sampling sewage system will remain, which is easy to breed microorganisms and affect environmental control. After the traditional fermentation tank is sampled, the staff usually carries a bucket of water and scoops water into each sampling sewage funnel. There are disadvantages such as forgetting to clean, delaying cleaning, large physical exertion, and incomplete cleaning due to insufficient flushing water. Utility Model Content

[0014] The present invention is further described below in conjunction with the accompanying drawings in order to better understand the present technical solution.
[0015] like Figure 1 As shown, a sterile sampling system for a biological fermentation tank with flushing and sewage discharge functions includes a fermentation tank body 1, one side of the fermentation tank body 1 is connected to a sampling near-tank valve 3 through a sampling pipe 2, one end of the sampling pipe 2 extends into the bottom of the fermentation tank body 1, and the other end of the sampling pipe 2 passes through the fermentation tank body 1 and is welded to the sampling near-tank valve 3. A sterilization system and a sampling valve 4 are respectively arranged on the side of the sampling near-tank valve 3 away from the fermentation tank body 1, and a sewage flushing system is arranged below the sampling valve 4.
[0016] The sterilization system includes a steam pipe 5 and a steam valve 6 arranged on the steam pipe 5. One end of the steam pipe 5 is connected to the sampling near-tank valve 3, and the other end of the steam pipe 5 is connected to a steam source for cleaning and sterilizing the sampling near-tank valve 3 and the sampling valve 4 before and after sampling.
[0017] The sewage flushing system includes a sampling sewage funnel 7 and a flushing pipe 8 arranged below the sampling valve 4. One end of the flushing pipe 8 is connected to the sampling sewage funnel 7. The connection between the flushing pipe 8 and the sampling sewage funnel 7 is a tangential connection. The other end of the flushing pipe 8 is connected to a water source. A flushing water valve 9 is installed on the flushing pipe 8 for cleaning the sampling sewage funnel 7 after sampling.
[0018] If the flushing water valve 9 of the present invention adopts a non-automatic valve, a foot valve installed on the ground or a hand valve installed at a height of about 1.2m can be used. After sampling, the flushing water valve can be opened by stepping on the foot valve or by hand to facilitate the flushing operation.
[0019] The sampling near-tank valve 3 and the sampling valve 4 are preferably stainless steel diaphragm valves, which can better control leakage and ensure aseptic control.
[0020] If all valves involved in the utility model are automatic valves, the self-control program design is carried out according to the following logic to start the sampling operation with one button: open the steam valve 6 and the sampling valve 4 to maintain the set time T1 (which can be freely set according to the process requirements), close the steam valve after the end, open the sampling near-tank valve 3 to maintain the set time T2 (which can be freely set according to the process requirements), close the sampling near-tank valve 3 after the end, open the steam valve 6 again, maintain the set time T3 (which can be freely set according to the process requirements), and open the flushing water valve 9 at the same time to maintain the set time T4 (which can be freely set according to the process requirements). After T3 time is up, close the steam valve 6 and the sampling valve 4, and after T4 time is up, close the flushing water valve 9. The sampling program is finished.
[0021] If the valve of the utility model is a non-automatic valve, the operation is as follows:
[0022] Pipeline sterilization before sampling: confirm that the sampling near-tank valve 3 is closed and the sampling valve 4 is open, open the steam valve 6, and use steam to sterilize the sampling valve 4 according to the process requirements;
[0023] Sampling: After the sterilization time is reached, close the steam valve 6, open the sampling near tank valve 3, let the fermentation liquid in the fermentation tank flow out with a certain force, first release a certain volume of fermentation liquid into the sampling drain funnel 7 below, and then use the sampling device to collect the sample. After sampling, close the sampling near tank valve 3.
[0024] Pipeline sterilization after sampling: the same as the pipeline sterilization method before sampling.
[0025] Cleaning the sampling and drain funnel: Open the flushing water valve and flush the sampling and drain funnel.
