Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for microbial fermentation in liquor production. Background Art

[0002] Baijiu is a distilled liquor made from grains as the main raw material, treated with saccharification and fermentation agents (such as Daqu, Xiaoqu, and Fuqu), and made through processes such as cooking, saccharification, fermentation, distillation, aging, and blending. It is colorless or slightly yellowish and transparent, with a pure and aromatic smell and a high alcohol content.

[0003] The microbial fermentation stirring device for liquor production is a core equipment used to mix microorganisms and raw materials during the fermentation process, promote oxygen transfer and maintain a stable fermentation environment. It can ensure full contact between microorganisms, raw materials and fermentation liquid through the rotation of stirring blades, thereby improving the saccharification and fermentation efficiency. Mechanical stirring accelerates the mixing of air and liquid, promotes aerobic respiration of microorganisms and meets oxygen consumption requirements.

[0004] The existing microbial fermentation stirring device for liquor production has the following shortcomings:

[0005] 1) The existing stirring device for microbial fermentation in liquor production. During the fermentation process of liquor, conventional stirring devices will cause stratification of raw materials with different densities, resulting in uneven distribution of microorganisms and inconsistent fermentation rates. In addition, traditional stirring relies solely on natural aeration by vortexes on the liquid surface, and the deep dissolved oxygen rate is low, which affects the reproduction of aerobic bacteria such as acetic acid bacteria, thereby resulting in insufficient production of flavor substances. In addition, the existing stirring device for microbial fermentation in liquor production has traditional stirring paddles that cannot cover the edge and bottom corners of the tank, and unfermented raw materials are easily left behind, requiring manual intervention for stirring later. In addition, solid particles such as sorghum and wheat settle to the bottom of the tank due to gravity, thus forming a "dead zone", which leads to insufficient contact between microorganisms and raw materials. Utility Model Content

[0006] The utility model proposes a stirring device for microbial fermentation in liquor production. By setting a composite dynamic dual-drive fermentation component, the rotating tank body can drive the material to tumble as a whole, eliminating tank wall attachment and bottom sedimentation. The fermentation liquid is often prone to stratification due to density difference, and the up and down movement is forced to break the static stratification, so that the distribution of microorganisms, oxygen and nutrients is more uniform, thereby effectively solving the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a stirring device for microbial fermentation of liquor production comprises a fixed base;

[0008] ‌Four support frames, fixedly connected to the top of the fixed base;

[0009] Four first fixing members are respectively fixedly connected to the outer surface of a corresponding one of the support frames;

[0010] A support base, fixedly connected to the tops of the four support frames;

[0011] A composite dynamic dual-drive fermentation component is fixedly connected to the top of the support base;

[0012] The composite dynamic dual-drive fermentation assembly includes a second fixing member, two electric push rods, and a second servo motor. The shaft end fixing sleeves of the two electric push rods are provided with a third fixing member. The bottom of the third fixing member is fixedly installed with a first servo motor. The two electric push rods are used for linear motion to push the first servo motor to linearly move. The output end of the first servo motor is fixedly connected to a transmission shaft, and a stirring blade is fixedly inserted at the bottom of the transmission shaft. The shaft end fixing sleeve of the second servo motor is provided with a stirring tank. The second servo motor converts electrical energy into mechanical energy to drive the stirring tank to perform uniform rotational motion.

[0013] The bottom of the second fixing member is fixedly connected to the supporting base;

[0014] The two electric push rods are fixedly mounted on the bottom of the second fixing member.

[0015] Preferably, four baffles are fixedly installed on the inner wall of the stirring tank, a discharge port is fixedly connected to the outer wall of the stirring tank, and a group of fourth fixing parts is fixedly connected to the top of the fixed base.

[0016] Preferably, a tank cover is fixedly connected between the outer walls of the four first fixing members, a roller bearing is fixedly installed inside the tank cover, and a feed port is fixedly connected to the top of the tank cover.

[0017] Preferably, the outer wall of the mixing tank is rotatably connected to the inside of the roller bearing.

[0018] Preferably, the second servo motor is fixedly packaged inside a set of fourth fixing members.

[0019] Compared with the prior art, the advantages and positive effects of the utility model are:

[0020] 1. In the utility model, by setting up a composite dynamic dual-drive fermentation component, the rotating tank body can drive the material to tumble as a whole, eliminate tank wall attachment and bottom sedimentation, and the fermentation liquid is often prone to stratification due to density difference, and the up and down movement is forced to break the static stratification, so that the distribution of microorganisms, oxygen and nutrients is more uniform.

[0040] The effect achieved by the entire embodiment 2 is: through the setting of four baffles 510, the baffles 510 destroy the symmetry and force radial and axial flows. The baffles 510 will cause the liquid to continuously fold during the rotation process, which can increase the frequency of gas-liquid interface renewal, thereby promoting the improvement of mixing efficiency.

At the same time, the stirring shaft rotates synchronously with the tank body, eliminating the wear of relative motion, and can completely solve the problem of dynamic seal leakage of traditional stirring. The composite dynamic dual-drive fermentation component 5 has been fully improved in mixing efficiency and microbial friendliness through the innovative integration of physical motion modes, and has successfully improved the efficiency of microbial fermentation in liquor production. When the required liquor is fermented, the fermented liquor is discharged from the discharge port 511.
