Abstract

The utility model discloses an air-lift fermenter. A filtering device is arranged on the exhaust pipe of the fermenting tank. The design is reasonable and the installation is convenient, which can effectively ensure that when the machine breaks down, the air will be filtered by the filtering device before returning to the tank body. , to avoid contamination of the product in the tank, thus greatly saving manpower.

Description

An air-lift fermenter

technical field

The utility model relates to the field of fermentation, in particular to an air-lift fermentation tank.

Background technique

Fermentation tank is an external environmental device that uses microorganisms to grow, reproduce and form products during fermentation. It is widely used in pharmaceutical, chemical, bioengineering, brewing and other industries. It can provide temperature, controllable temperature, pressure, and can provide good stirring conditions. However, the fermenter in the prior art requires long-term manual care. When the machine equipment fails, the connection between the fermenter and the outside world is manually closed to ensure that the product in the tank is not polluted, but this is in many unexpected situations and greatly wastes manpower. .

Contents of the invention

Aiming at the problems existing in the prior art, the utility model provides an air-lift fermenter. By setting a filter device on the exhaust pipe of the fermenter, the design is reasonable and the installation is convenient, which can effectively ensure that the air will flow back when the machine breaks down. Before entering the tank, it is filtered by the filter device to avoid contamination of the product in the tank, thus greatly saving manpower.

In order to solve the above technical problems, the technical solution adopted by the utility model is an air-lift fermenter, which includes a tank body and a first air inlet, a second air inlet, and an air outlet arranged on the tank body, the first The air inlet is connected to the air inlet pipe, the second air inlet is connected to the steam pipe, the air outlet is connected to the exhaust pipe, and a filtering device is arranged on the exhaust pipe, through which the air compressor can be avoided. When a failure occurs, the external air returns to the tank to pollute the fermentation product.

As a preference of the solution, a manual control ball valve is provided on the exhaust pipe.

As a preference of the scheme, the filtering device is a filter.

The beneficial effect of the utility model is that, an air-lift fermenter, by setting a filtering device on the exhaust pipe of the fermenter, the design is reasonable, the installation is convenient, and it can effectively ensure that when the machine fails, the air will flow back to the tank before Filtered by the filter device to avoid contamination of the product in the tank, thus greatly saving manpower.

detailed description

Now in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a kind of air-lift fermenter, comprises tank body and the first air inlet that is arranged on the tank body, the second air inlet, air outlet, the first air inlet is connected with air inlet pipe, the second The second air inlet is connected to the steam pipe, the air outlet is connected to the exhaust pipe, and a filter device is arranged on the exhaust pipe, through which the external air can be prevented from returning to the tank body when the air compressor fails. fermentation product.

Wherein, the exhaust pipe is provided with a manual control ball valve.

Wherein, the filtering device is a filter.

The utility model is installed on the exhaust pipe of the tank body. Before working, steam enters the tank body through the steam pipe and performs high-temperature sterilization on the tank body and the filter connected with the tank body. The sterilization requirement is to keep the temperature at 125°C After 40 minutes in a high temperature environment, after starting to work, when the air compressor connected to the inlet pipe of the tank fails, it cannot provide pressure to the tank normally. At this time, the external air enters the tank through the exhaust pipe by virtue of the pressure difference , through the filter device provided by the utility model, it is ensured that the backflow gas will not pollute the fermented product in the tank, and there is no need for manual long-term care, thereby greatly saving manpower.

For those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or to perform equivalent replacements for some of the technical features, and any modifications made within the spirit and principles of the present utility model , equivalent replacement, improvement, etc., should all be included in the protection scope of the present utility model.
