Abstract

PURPOSE:To prevent the accumulation of solid material in a branched pipe, and prevent the blocking of the pipe, by connecting a medium feed pipe to the lower end of a vertical branch header, and connecting the header to a culture tank via a plurality of inclined ascending branch pipes. CONSTITUTION:A medium 1 containing precipitable solid material is fed through the heat-recovery apparatus 2, the heater 3, the retention pipe 4, the cooler 5 and the medium feed pipe 6 and transferred upward in the vertical branch header 7. The cut-off valve 11 is opened, the cut-off valves 12, 13 are closed, and the medium 1 is supplied through the inclined ascending branch pipe 8 to the culture tank 14. The medium supplied to the branch pipes 9, 10 is stopped at the valves 12, 13 to precipitate the solid material, which is flowed down in the header 7 along the inclined wall of the branch pipes 9, 10, combined with the medium 1 flowing toward the branch pipe 8, and introduced into the culture tank 14.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to piping for transporting culture medium in a culture plant, and in particular, to a pipe for transporting a sterilized culture medium containing sedimentary solids to a plurality of culture tanks. This is related to ladder piping to the branches necessary to do so.

[Background of the invention]

The most similar is that the medium flowing in the transport P pipe is fed in a turbulent state by increasing the flow rate to prevent solids from settling. In case 2, if there is a horizontal dead end in the piping, solids with a large specific gravity will flow into the dead end due to the inertia of the pipe, and since there is no flow of liquid there, the solids will settle and accumulate, causing the piping to collapse. occlude. Therefore, even if one goo piping is connected to a branch that sends sterilized culture medium containing sedimentary solids to multiple culture tanks, a dead end will occur in the branch pipe where liquid feeding is stopped, and the solids will settle. There is a problem of accumulation and blockage of one branch pipe. An example of transportation of sterilized culture medium is [Optimum measurement and control of fermentation process] Comprehensive technical data collection, February 28, 1981, published by Science Forum Co., Ltd., 71-72 [Measurement and control of continuous sterilization 1] There is.

[Purpose of the invention]

An object of the present invention is to prevent blockage of branch pipes due to accumulation of solids in the 7-goo piping to the branches that send sterilized culture medium containing sedimentary solids to a plurality of culture tanks.

[Summary of the invention]

The present invention provides a single branch in medium transport piping that transports sterilized medium containing sedimentary solids to multiple culture tanks via branch headers and branch pipes! Install the goo vertically, connect the culture medium supply piping to the bottom end of the branch header, and
A plurality of branch pipes inclined upward are connected to the branch header, and each branch pipe is connected to the culture tank via a shutoff valve, and the solid content that has settled in the branch pipe where liquid feeding is stopped is removed. By returning the solids to the branch header, the solid content is accumulated in the branch pipe, thereby preventing clogging of the first branch pipe.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1+*l, 82, l is a medium containing sedimentary solids, 2 is a heat recovery device, 3 is a heater, 4 is a retention tube, 5
is a cooler, 6 is a culture medium supply pipe, and 7 is a vertically installed branch header, to which the culture medium supply pipe 6 is connected to the lower end. 8 to 10 are branch pipes connected to the branch with an upward slope, and branch pipes 8 to 10 are connected to culture tanks 14 to 16 via shutoff valves 11 to 13, respectively. .

In the above-described configuration, the culture medium 1 is passed through the heat recovery device 2 at a flow rate that does not cause settling of solids. Heater 3. It is sterilized through a retention pipe 4, and then transferred to a heat recovery device 2. After being cooled to a predetermined temperature through the cooler 5, the medium is introduced from the lower end into the budder 7 through a branch from the medium supply pipe 6.

Now, regarding the case where the culture medium is supplied to the culture 1' 114, it is supplied into the culture tank 14 through the cutoff valve 11. in this case.

The sterile culture medium is transferred to the branch header 7 and the branch pipe 9 above the connection position of the branch pipe 8. It also flows into IO, but the deadline minister,
Since 13 is closed, it is a complete dead end, and the solid content contained in the sterile medium causes sedimentation, but it branches! The solid content settled in 9.10 is transferred to branch pipe 9. It flows along the slope of lO to the branch into the first nodder 7 and flows into the first branch together with the solid content that has settled in the t-dart inside the branch header 7 into the branch pipe 8.
It descends to the connection position, joins the flow of the culture medium to the branch pipe 8, and flows into the culture tank 14. Therefore, the branch header 7 and the branch pipe 9. A sterile medium can be supplied to the culture tank 14 while preventing blockage due to accumulation of solids in the IO. Also, the shutoff valve 12 is opened, and the shutoff valve 11.13 is opened.
Even when the switch is made to supply the culture medium to the culture tank 15 by closing the branch header 7 and the branch pipe 8.
The sterile culture medium can be supplied to the culture tank 15 while preventing clogging of the to.

〔Effect of the invention〕

As described above, the present invention allows the solid content that has settled in the branch pipe that does not send liquid to flow down into the branch header along the upward slope provided in one branch pipe and merges with the flow of the branch pipe that sends liquid. This system prevents blockage due to accumulation of solids in the branch pipes and in the branch pipes, and allows the sterile medium containing sedimentary solids to flow into multiple culture tanks. You can supply two things.
