Description

TECHNICAL FIELD

[0001] The utility model relates to a grain vinegar production equipment technical field, concretely relates to a mixing device for grain vinegar generation. BACKGROUND

[0002] The raw materials of grain vinegar production usually include rice, wheat, sorghum, bran, and rice chaff, etc. Mixing is an important link in the brewing process, and includes pretreatment of raw materials, cooking and gelatinization, cooling, addition of saccharifying agent and water, preliminary stirring and mixing, addition of yeast and bran, rice chaff and other auxiliary materials, and finally uniform mixing.

[0003] According to the disclosure (announcement) number: CN118406541B, the disclosure (announcement) date: 2024-09-27, a kind of coarse grain vinegar and production process, including the closed container for stirring treatment raw materials, and closed container is provided with the stirring component of stirring raw material mixture.

[0004] In the prior art including the above patent, the preliminary stirring and mixing time in the step should not be too long to avoid the temperature rise of the material caused by stirring, which affects the biological activity and saccharification effect. When yeast and bran, rice chaff and other auxiliary materials are added, there are still a small amount of biological reactions and saccharification that have not completely ended in the material. The purpose is to add yeast when saccharification reaches a certain stage, which can make the yeast start to grow and ferment under suitable sugar concentration and other nutrients. Bran, rice chaff and other auxiliary materials can provide more nutrients and growth space for microorganisms (including yeast and subsequent acetic acid bacteria involved in acetic acid fermentation), increase the permeability of the material, and be beneficial to the growth and metabolism of microorganisms. Therefore, the stirring time in the container should not be too long when yeast and bran, rice chaff and other auxiliary materials are added. However, since the bran, rice chaff and other raw materials are in the form of particles that are easy to float, they will slowly settle on the surface of the material after being added to the container, which will take a long time to enter the interior of the material. Therefore, the mixing is not uniform when stirring again, and the reaction period is prolonged, which reduces the production efficiency of brewing. UTILITY MODEL CONTENTS

[0027] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model will be introduced further in detail below with the accompanying drawings.

[0028] As Figures 1-4 Indicated, a kind of mixing device for grain vinegar generation, including tank body 1, still including the stirring pipe 2 with pipe shell 21, multiple stirring rods 4 are hingedly arranged on the side of pipe shell 21, and round head 41 located in pipe shell 21 is arranged at the end of stirring rod 4;

[0029] Still including vertical rod 3 with round plate 32, multiple protrusions 33 are fixedly installed on the end face of round plate 32, wherein:

[0030] Protrusion 33 is in turn slidably contacted with multiple round heads 41, so that stirring rod 4 is deflected by a predetermined angle, and rod gap 42 opened in the lower end surface of stirring rod 4 is matched with the surface of material in tank body 1.

[0031] Specifically, the port of pipe shell 21 is greater than the inner diameter of stirring pipe 2, and torsional spring is arranged at the hinged position of stirring rod 4, and the torsional spring keeps stirring rod 4 horizontal in default state.

[0032] Further, fixedly installed round plate 32 is located in pipe shell 21, and lever principle is used in the process of round head 41 being contacted and sliding, and round head 41 after being rounded and protrusion 33 can make the sliding process more smooth.

[0033] As the stirring rod 4 rotates, it is pushed by multiple protrusions 33, causing it to intermittently switch between tilting and returning to a horizontal state. This means that the material corresponding to the position of the protrusion 33 is turned up and down. The purpose is to turn the bran, rice husks, and other raw materials falling from the surface of the material into the interior of the material. Then, circumferential stirring is used to improve the mixing effect of the raw materials. During the process, the end of the rod notch 42 is in a downward snapping motion, which allows the raw materials to be directly picked up and sent into the interior of the material. This shortens the time that the raw materials need to be constantly stirred on the surface of the material to sink. The purpose is to further improve the mixing efficiency of raw materials such as bran and rice husks with the original materials in the tank 1 within a short stirring time, reduce the impact on the reaction cycle, and ensure the original brewing production efficiency.

[0034] As a further embodiment of this utility model, the stirring rod 4 is provided with symmetrically arranged side shells 43, and the side shells 43 are provided with protrusions that maintain a predetermined angle with them.

[0035] Specifically, the side shell 43 makes the rod notch 42 appear in the shape of the character "Ohm".

[0036] The side shell 43, which rotates circumferentially, uses its inclined surface to guide the material and allow it to flow downwards along the inclined surface. This means that the material mixed with the raw materials can be replenished inwards, thereby increasing the depth of material feeding. The inclined surface at the raised position provides an upward curling conveying function, and during the circumferential stirring process, the upward curling material is radially diffused, forming a material conveying trajectory similar to a spiral direction, making the mixing of raw materials more diverse. Furthermore, the stirring rod 4 can produce a stirring effect in both forward and reverse rotation.

[0037] As another embodiment further provided in this utility model, an inner inclined surface 44 is provided in the rod notch 42.

[0038] Specifically, the right-angle position of the inner inclined surface 44 is located on the hinge side of the stirring rod 4.

[0039] The inner inclined surface 44 can push the material at the center of the stirring tube 2 toward the inner wall of the tank 1 during the process of the stirring rod 4 returning to horizontal, so that the raw material mixing process also has a radial conveying effect.

[0040] As another embodiment further provided by this utility model, an inclined inlet 22 located below the upper surface of the material is provided on the side wall of the stirring tube 2.

[0041] Specifically, a curved surface is provided in the inclined inlet 22, and this curved surface is equivalent to the curved surface of the impeller. The purpose is to provide a stirring effect for the material around the stirring tube 2. The principle and the premise of its generation are existing technologies and will not be elaborated here.

[0042] The circumferentially arranged inclined inlets 22 can draw the raw material from the upper surface of the material near the axis downwards, increasing the area of ​​the raw material mixture and reducing the floating time of the raw material, thus reducing the waste of stirring time. During the stirring process, the middle of the material is concave, so that the exposed part of the inclined inlet 22 is above the material, which increases the chance of the raw material on the upper surface of the material falling into the inclined inlet 22.

[0043] As another embodiment of this utility model, a lower discharge port 23 is also provided on the side wall of the stirring tube 2, which communicates and cooperates with the inclined inlet 22.

[0044] The raw materials are pumped in and transported through the mixing tube 2 before being discharged from the lower outlet 23. This means that the raw materials are mixed inside the mixing tube 2, and can also be directly transported downwards through the shaft to deeper layers of material.

[0045] As another embodiment of this utility model, a plurality of auger blades 24 that cooperate with the inclined inlet 22 are fixedly installed on the inner wall of the stirring tube 2.

[0046] Specifically, the upper end of the auger plate 24 is located between adjacent inclined inlets 22, and the auger plate 24 is embedded in the material in the stirring tube 2.

[0047] The auger plate 24 enhances the suction capacity of the inclined inlet 22, making the material conveying effect more obvious. At the same time, the downward conveying function of the auger plate 24 allows the material to be discharged downwards to the lower outlet 23 and the lower port of the pipe shell 21.

[0048] As another embodiment further provided in this utility model, the stirring rod 4 is specifically a stainless steel metal rod.

[0049] The stainless steel rod makes the stirring rod 4 more resistant to wear and corrosion, and makes the stirring rod 4 and its thinner parts less prone to deformation, thus ensuring a variety of mixing effects on materials.

[0050] As another embodiment further provided in this utility model, the circular plate 32 is specifically a circular steel plate.

[0051] The use of steel plates ensures that the circular plate 32 is not easily deformed under long-term stress, thus guaranteeing the ability to drive the lifting force of the stirring rod 4.

[0052] As another embodiment further provided in this utility model, the deflection angle of the stirring rod 4 is specifically 0-45°.

[0053] The deflected stirring rod 4 allows its end to extend upwards above the material surface, enabling the stirring rod 4 to cover a larger area and achieve higher mixing efficiency.

[0054] As another embodiment provided in this utility model, the inclination angle of the inner inclined surface 44 is specifically 1°.

[0055] The inner inclined surface 44 is longer due to its smaller inclination angle, with the aim of having a larger radial pushing area.

[0056] Working principle: During the rotation of the stirring rod 4, it is pushed by multiple protrusions 33, and the rod intermittently switches between tilting and returning to a horizontal state. This means that the material corresponding to the position of the protrusion 33 is turned up and down. The purpose is to turn the bran, rice husks and other raw materials falling from the surface of the material into the interior of the material. Then, circumferential stirring is used to improve the mixing effect of the raw materials. During the process, the end of the rod notch 42 is in a downward snapping motion, so that the raw materials can be directly picked up and fed into the interior of the material, shortening the time that the raw materials need to be constantly stirred on the surface of the material to sink. The purpose is to further improve the mixing efficiency of raw materials such as bran and rice husks and the original materials in the tank 1 within a short stirring time. In addition, the inner inclined surface 44 can push the material at the axis of the stirring tube 2 towards the inner wall of the tank 1 during the process of the stirring rod 4 returning to a horizontal state, so that the raw materials also have a radial conveying effect during the mixing process.

[0057] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
