Description

Technical Field

[0001] The invention relates to the technical field of microorganism cultivation, and in particular to a device for efficiently propagating microorganisms. Background Art

[0002] Microbial cultivation refers to the preparation of nutrients for the growth and reproduction of microorganisms according to their different needs, which is used to cultivate, separate, identify, preserve microorganisms or accumulate their metabolites. Microbial propagation refers to the process of rapidly increasing the number of microorganisms through certain technical means based on microbial cultivation. The existing propagation method usually directly puts the strain into the strain carrier and then provides a certain humidity and temperature environment. It is difficult to achieve precise control during the propagation process, thus affecting the propagation efficiency.

[0003] In this regard, the patent application document with application publication number CN116731826A discloses an intelligent microbial strain propagation device, which includes a frame, on which a sterilization mixing tank, a first drive motor, a water tank and a control system are installed, and an oxygen supply fan, a water tank, a breathable plate, a humidity sensor, a temperature sensor, a heater, a second drive motor and a conveying auger are installed in the frame, the first drive motor, the oxygen supply fan, the humidity sensor, the temperature sensor, the heater and the second drive motor are electrically connected to the control system, the sterilization mixing tank includes a tank body and a stirrer, the first The driving motor is connected to the agitator, and the agitator is arranged in the tank body. The side of the tank body is provided with an electric control door connected to the water tank. The air permeable plate is tilted in the water tank and is received under the electric control door. A plurality of air holes are provided on the air permeable plate. The temperature sensor and the heater are inserted into the water tank at positions corresponding to the bottom of the water tank. The humidity sensor is inserted into the water tank at a position corresponding to the top of the air permeable plate. The oxygen supply fan is installed on the side of the water tank. The second driving motor is also installed on the side of the water tank and connected to the conveying auger. The conveying auger is arranged along the lower edge of the air permeable plate. A discharge port is provided on the side of the water tank at a position corresponding to the end of the conveying auger.

[0004] It can be seen that the above-mentioned device heats the water in the water tank to generate water vapor to adjust the temperature and humidity required by the material above the water tank to achieve efficient expansion effect. However, the above-mentioned device still has the following problems when in use: 1. The stability of water vapor heating is poor, and the temperature of water vapor is easily affected by external factors such as season and pressure; 2. During the heating process, water vapor will significantly increase the humidity of the environment, increasing the difficulty of humidity control; 3. During the heating process, water vapor undergoes a transformation from liquid to gas, which requires a large amount of energy, and water vapor is prone to heat loss during the heat transfer process, resulting in low energy efficiency of water vapor heating. Summary of the invention

[0005] The invention provides a microorganism efficient propagation device to solve the technical problems of poor heating stability and large heat loss of the propagation device in the prior art.

[0006] In order to solve the above problems, the microbial efficient propagation device provided by the present invention adopts the following technical solutions: A microorganism efficient propagation device, comprising: The silo is mounted on a bracket, a stirring shaft extending along its length is passed through the silo, blades are mounted on the stirring shaft, the bottom plate of the silo is a concave arc bottom plate, a discharge port is provided on the arc bottom plate, a discharge control valve is provided at the discharge port, and a first execution cylinder for controlling the opening and closing of the discharge control valve is mounted on the bracket; A feed hopper, which is in communication with the side of the bin body and is used to feed materials into the bin body; A heat transfer oil storage chamber is installed on the arc bottom plate. The heat transfer oil storage chamber is a concave and hollow arc structure. A heating plate is installed on the outside of the heat transfer oil storage chamber. The heating plate is wrapped with an insulation layer. A temperature sensor is installed on the heat transfer oil storage chamber. A driving assembly connected to the stirring shaft to drive the stirring shaft to rotate; The feed port of the feed hopper is rotatably mounted with an upper cover, and the top of the bin body is provided with a second actuator cylinder connected to the upper cover for opening or closing the upper cover; A pneumatic device, which is mounted on the bracket and connected to the first actuating cylinder and the second actuating cylinder; A control cabinet is connected to the temperature sensor, the heating plate and the pneumatic device by signals.

[0007] Firstly, a heat transfer oil storage chamber is arranged at the bottom of the bin body, and the heat transfer oil storage chamber is a concave and hollow arc structure, so that the cooperation between the heat transfer oil storage chamber and the blades is more closely, which is helpful for the material to form a continuous circulation flow during the stirring process and improve the contact effect between the material and the heat transfer oil.

[0016] Furthermore, there are multiple blades, and the multiple blades are arranged in a spiral shape in the circumferential direction of the stirring shaft.

[0017] Furthermore, the stirring shaft is a segmented structure, which includes a tube shaft, and the two ends of the tube shaft are respectively connected to a driving shaft and a tail shaft, and the driving shaft is connected to the driving assembly.

[0018] The mixing shaft is designed as a segmented structure, which is easy to disassemble and transport, greatly reducing the difficulty and cost of transportation and installation.

[0019] Furthermore, bearing seats are provided at both ends of the stirring shaft, bearings are installed in the bearing seats, and the ends of the stirring shaft are inserted into the bearings.

[0020] Furthermore, the discharge control valve is a plug-in plate valve structure, which includes a plug-in plate and a valve body, and the valve body is provided with a slideway for installing the plug-in plate.

[0021] Furthermore, the warehouse body is a stainless steel warehouse body.

[0022] Stainless steel has excellent load-bearing capacity, corrosion resistance and wear resistance. Making it into a warehouse body can greatly increase the service life of the warehouse body.
