Material mixing and fermenting device

Abstract

The invention relates to a material mixing and fermenting device. The material mixing and fermenting device comprises a tank body, a temperature measuring device, a rotating shaft, blades, a defoaming device, three tank body supports, an electric stove plate, a motor, a shaft coupling, a frequency converter and a motor support. The top of the tank body is provided with a feed port, a lifting lug and a manhole, the tank bottom is in a flat bottom structure, a discharge port is formed in the tank bottom, the temperature measuring device is positioned on the side wall of the tank body, and the temperature measuring device can directly observe a temperature value in the tank from the outside of the tank; the top of the rotating shaft is connected with the shaft coupling, and the bottom of the rotating shaft is articulated with a support seat on the bottom surface in the tank body; the blades are crisscross arranged on the rotating shaft; the defoaming device is positioned on the rotating shaft and can timely eliminate liquid bubbles produced by stirring; the three tank body supports are uniformly distributed on the side wall of the tank body; one end of the shaft coupling is connected with the rotating shaft, and one end of the shaft coupling is connected with the motor; the frequency converter is connected with the motor and can adjust the rotational speed of the motor; the material mixing and fermenting device has the advantages of simple heating structure, low cost, convenience in maintenance, uniformity in material mixing, safety and reliability.

Description

technical field [0001] The invention relates to a fermentation device, in particular to a material mixing fermentation device, which belongs to the technical fields of bioengineering, pharmacy and fine chemical industry. Background technique [0002] The fermentation device is a kind of equipment for stirring and fermenting materials, which is widely used in bioengineering, pharmaceutical, fine chemical and other industries. The stirring devices of the general fermenter are all turbine agitators with the same diameter, and the material is heated by the heating device, and the material is rapidly fermented at a constant temperature. Because different microorganisms have different temperature requirements, lower or higher than the optimum temperature will cause slow growth or death of microorganisms, therefore, the fermentation temperature should be kept relatively stable. Traditional fermentation tanks mainly rely on the heating device installed in the tank to control the he...

AI Technical Summary

Problems solved by technology

The traditional fermentation tank controls the heating temperature in the tank mainly by means of a heating device installed in the tank. This heating device is easy to damage, has low safety performance, and has a complex structure, high cost, and inconvenient maintenance.

In addition, ordinary fermenters often produce some liquid bubbles when stirring, which is not conducive to observation and may also affect the quality of fermentation
