Description

Microorganism solid fermentation device

Technical Field

The utility model relates to a microorganism solid fermentation device.

Background

Microbial fermentation refers to a process of converting raw materials into products required by human beings through a specific metabolic pathway by using microorganisms under appropriate conditions, and is widely applied to the fields of medicine industry, food industry, energy industry, chemical industry, agriculture and the like. In the process of microbial solid fermentation, due to poor flowability of solid raw materials, the difficulty of inoculating and mixing strains is high, and the strain inoculation uniformity in the conventional fermentation device or equipment is limited, so that the fermentation process and the quality of a final product are influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a microbial solid fermentation device with uniform strain inoculation.

The microbial solid fermentation device according to the present invention comprises:

a fermentation tank body;

the linear blind pipe is provided with an open end, a closed end and a pipe wall, extends across the interior of the fermentation tank body and is rotatably arranged relative to the fermentation tank body, and a series of radial convex teeth and a series of spray heads communicated with the interior of the blind pipe are respectively arranged on the pipe wall along the length direction of the linear blind pipe;

the bacteria liquid feeding mechanism is in fluid communication with the open end of the blind pipe; and

and the rotating mechanism is positioned outside the fermentation tank body and used for rotating the blind pipe.

According to the utility model, the fermenter body can be provided with a closable feed opening. In addition, a closable ventilation mechanism can be arranged on the fermentation tank body. These closable features of the fermenter body facilitate the selective inoculation of aerobic or anaerobic bacteria.

According to the utility model, the rotation mechanism comprises a motor. Of course, it can also be simply provided as a hand-operated mechanism, depending on the actual application.

According to the utility model, the bacteria liquid feeding mechanism comprises a pressurizing pump connected with the bacteria liquid supply source and a liquid supply spray pipe which is connected with the pressurizing pump and is aligned with the open end of the blind pipe. By starting and stopping the pressurizing pump, intermittent feeding of the bacteria liquid can be performed as required.

According to the utility model, the blind pipe can be a horizontally arranged blind pipe. The horizontal fermentation tank is more beneficial to the uniform mixing of raw materials or materials.

According to the utility model, a bracket for supporting the tank body can be further included.

The microbial solid fermentation device can force the bacterial liquid to be uniformly injected into the solid material along the axial direction through the structural mode that the spray heads are arranged on the stirring hollow shaft which is in fluid communication with the bacterial liquid feeding mechanism, and then the bacterial liquid can further uniformly permeate into the material in the radial direction through the rotation of the stirring shaft by virtue of centrifugal force. In addition, the amount of the injected or sprayed bacteria can be controlled at any time by starting and stopping the pressure pump along with the fermentation condition in different stages of fermentation, so that the fermentation can be carried out more efficiently. In a word, the microbial solid fermentation device has simple structure and convenient operation, can fully mix the bacterial liquid and the raw materials, improves the quality of fermentation products, and is convenient to control the fermentation process.

Drawings

FIG. 1 is a schematic view of the structure of a microbial solid fermentation apparatus according to the present invention.

Detailed Description

The present invention is further described below in conjunction with the following examples and figures, which are to be understood by those skilled in the art as being solely for the purpose of better understanding the present invention and not for the purpose of limiting same.

Fig. 1 shows a microbial solid fermentation device according to the present invention, which comprises a fermentation tank body 1, a horizontal blind pipe (hollow stirring shaft) 2, a bacteria liquid feeding mechanism and a rotating mechanism 9.

The fermenter body 1 shown is a horizontal cylinder arranged on a support 3 and has a feed opening 4 in the form of a rotatably closed lid. A plurality of vent holes 8 are arranged above two side walls of the fermentation tank body 1, and a pivotable baffle 7 is arranged at the corresponding position of the side walls and used for opening and closing the vent holes 8.

The blind pipe 2 has a left closed end and a right open end, is rotatably arranged relative to the fermenter body 1, horizontally extends across the inside of the fermenter body 1, and is provided with a series of radial protruding teeth (stirring teeth) 6 and a series of nozzles 5 which are in fluid communication with the inside of the blind pipe, respectively, on the pipe wall along the length direction. The spray head 5 may take the form of a simple spray orifice or a shower head which may further increase the spray area.

The bacteria liquid feeding mechanism comprises a pressurizing pump 11 connected with the bacteria liquid supply source 10 and a liquid supply spray pipe which is connected with the pressurizing pump 11 and is aligned with or extends into the right open end of the blind pipe 2. By turning on and off the booster pump 11, the inoculum feed mechanism can be brought into selective fluid communication with the blind pipe 2.

The rotating mechanism 9 is in the form of a crank driven by a motor, is positioned outside the fermentation tank body 1, is connected with the right end of the blind pipe 2 and is used for rotating the blind pipe 2. Of course, the rotating mechanism 9 may be simply provided as a crank handle without using a motor.

The operation of the microbial solid fermentation apparatus of the present invention will be briefly described below.

The raw material or material to be fermented, such as organic fertilizer, is first loaded into the fermenter 1 through the feed port 4 (e.g., occupying two thirds of the volume of the fermenter). Then, the inoculated bacteria liquid is pumped into the right open end of the blind pipe 2 from the bacteria liquid supply source 10 by using the pressure pump 11, after the bacteria liquid is uniformly injected into the materials by the spray heads 5 arranged along the transverse direction or the horizontal direction for a required time, the pressure pump 11 is closed, then the motor is started to rotate the blind pipe 2 through the rotating mechanism 9, and the materials are stirred so that the bacteria liquid in the materials can be diffused along the radial direction. Of course, the stirring operation may be performed while the bacterial solution is being added.

During stirring, the feed port 4 and the vent hole 8 of the fermentation tank body 1 are closed, and when stirring is stopped, the feed port 4 and the vent hole 8 can be selectively opened or closed according to the inoculated strain type (aerobic bacteria or anaerobic bacteria).
