Abstract

The utility model relates to an automatic spawn-inoculating device for a fermentation system, which is provided with a three-stage tank which mainly comprises a first stage spawn tank, a second stage spawn tank and a fermentation tank. The utility model is characterized in that a small tank capable of transferring spawns is respectively arranged between the first stage spawn tank and the second stage spawn tank and between the second stage spawn tank and the fermentation tank. The small tank is provided with a steam input/output control valve which is communicated with the first stage spawn tank, the second stage spawn tank and the fermentation tank. Both ends of a transmit pipeline are respectively provided with an input/output valve. The spawn transferring direction among multiple tanks can be realized through the control valve, and the convenient spawn transfer can be realized between the tanks according to the user's selection and needs. The automatic spawn-inoculating device realizes the automatic spawn inoculation in the process that the user transfers the spawns, widens the spawn transferring selectivity and reduces the living contaminants. The use is convenient.

Description

Automatic inoculation device for fermentation system

technical field

The invention relates to biological fermentation equipment, in particular to an automatic inoculation device for a fermentation system.

Background technique

Biological fermentation is a process of step-by-step amplification, and the tank volume magnification is generally 10 to 15 times. If this range is given, the environment will be different, and the fermentation product will also change, which cannot meet the requirements of fermentation. Such as 10L ~ 100L ~ 1000L such as three-stage fermentation, first prepare bacteria from the swing bed, and then inoculate into the first-stage 10L seed tank, after the fermentation is complete, transplant it into the second-stage 100L seed tank, and then ferment , the seeds are made and moved to a 1000L fermenter for fermentation, and finally the product can be produced, but it is easy to contaminate miscellaneous bacteria in the process of transplanting at each level. In a fermentation factory, there will be multiple sets of multi-stage fermentation equipment, and the fermentation equipment cannot be absolutely one-to-one correspondence, and cannot be fully utilized.

Contents of the invention

In the use of multiple sets of multi-stage fermentation equipment, in order to facilitate production and reduce the contamination of bacteria, the utilization rate of the equipment can be greatly improved only by transplanting each other. A paired transplanting device between each fermentation equipment.

An automatic inoculation device for a fermentation system, equipped with three-level tanks, mainly a first-level seed tank, a second-level seed tank, and a fermentation tank, characterized in that: between the first and second-level seed tanks, the second-level seed tank and the fermentation tank A small tank that can transfer strains is installed between them. The small tank has steam input and output control valves. It communicates with the primary and secondary seed tanks and fermentation tanks through the transmission pipeline. Input and output valves are set at both ends of the transmission pipeline. The direction of transplanting between multiple tanks can be realized by controlling the valve, and convenient transplanting between tanks can be realized according to the user's choice.

The device realizes the automatic inoculation of the user during the transplantation process, increases the selection degree of transplantation, reduces the contamination of miscellaneous bacteria, and is very convenient to use.

Detailed ways

As shown in Fig. 1, the present invention is mainly provided with three-level tank---one-level seed tank (7), two-level seed tank (11), fermenter (12), in one and two-level seed tank (7) (11 ), between the secondary seed tank (11) and the fermenter (12), respectively added a middle tank 10), and the steam input valve (3) of the middle tank (10) is located at one side of the cylinder of the middle tank (10) , the steam output valve (9) is located on the other side; one end of the primary seed tank output pipe (8) is controlled by the primary seed tank output valve (1), connected to the middle of the primary seed tank body, and extends to the bottom of the tank , the other end is controlled by the tundish tank input valve (2) and connected to the tundish tank (10); one end of the secondary seed tank input pipe (5) is controlled by the tundish tank output port valve (4) and connected to the tundish tank (10) , and extend to the bottom of the tank, the other end is controlled by the secondary seed tank input port valve (6), connected to the top of the secondary seed tank (11); the primary seed tank output valve (1), the secondary seed tank input port Valve (6), the outlet valve of the secondary seed tank and the inlet valve of the fermenter all use a steam outlet.

The automatic transplanting process between the primary seed tank (7) and the secondary seed tank (11):

1) Close all outlet valves (1) of the first-level seed tank (7) and all input valves (6) of the second-level seed tank before transplanting. The stage seed tank (11) is subjected to high-pressure steam sterilization, and the valve is closed after maintaining for 30min to 40min; the steam input valve (3) on the intermediate tank (10) is opened to feed steam, and the output pipe of the stage seed tank that needs to be used for transplanting (8) Sterilize the input pipeline (5) and the intermediate tank (10) of the secondary seed tank for inputting bacteria, and close all steam inlets and outlets after maintaining for 30 minutes to 40 minutes.

2) Open the outlet valve (1) of the primary seed tank (7), the intermediate tank input port valve (2), the intermediate tank output port valve (4), and the secondary seed tank input port valve ( 6);

3) Automatic transplantation.

The automatic transplantation between the second-level seed tank (11) and the fermenter (12) is similar to that between the first and second-level seed tanks.
