Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer for raw materials in wine-making and koji-making. Background Art

[0002] Koji is a substance that plays a role in saccharification and fermentation during the wine-making process. It is a fermented glutinous rice made from grains such as rice and wheat. Adding koji is an important step in the wine-making process. When making koji, it is necessary to control the proportion of miscellaneous grains such as wheat and corn, and fully stir and mix them in proportion.

[0003] Existing mixers are all single-shaft. When rotating, they can only drive the mixing blades to rotate in one direction. For example, in a common horizontal mixer, most of its interior is just a single mixing shaft.

[0004] Another example is a rapid mixer for raw materials in wine-making and koji-making proposed in the patent application No. "202022401036.4", which only has a single mixing rod inside, and mixing blades are provided on the mixing rod. Another example is a rapid mixer for raw materials in wine-making and koji-making proposed in the patent application No. "202322676836.0", whose internal mixing component is a transmission shaft, and blades are provided on the transmission shaft.

[0005] The single-shaft mixing shaft can only have one mixing direction, and there are certain limitations in the mixing efficiency, resulting in a relatively low mixing efficiency of koji. Therefore, we propose a mixer for raw materials in wine-making and koji-making. Content of the Utility Model

[0006] Aiming at the deficiency that the mixing shaft inside the existing mixer can only rotate in one direction, the utility model provides a mixer for raw materials in wine-making and koji-making, which has the advantages that mixing components are provided both inside and outside, and the internal and external components rotate simultaneously and in opposite directions during mixing, so that the materials can be mixed more quickly, and solves the problems raised in the above background art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a stirrer for raw materials of brewing koji, including a stirring tank 12, a support leg 16 is provided at the bottom of the stirring tank 12, a stirring mechanism is provided inside the stirring tank 12, the bottom of the stirring tank 12 is of an arc structure, the stirring mechanism is located inside the arc structure, a discharge port 20 is provided at the bottom of the stirring tank 12, and a valve is provided on the discharge port 20. During actual operation, the koji and fermented substances placed in the stirring tank 12 are stirred by the stirring mechanism, and after stirring, they are discharged through the discharge port 20.

[0036] As Figure 1 and Figure 2 , Figure 3 shown, the stirring mechanism includes a mounting shaft 1, both ends of the mounting shaft 1 are respectively rotatably mounted in the support sleeves 8, and the two support sleeves 8 are respectively rotatably provided on the side surfaces at both ends of the stirring tank 12, so that the support sleeves 8 can rotate freely inside the stirring tank 12, and the mounting shaft 1 can rotate freely inside the support sleeves 8;

[0037] The two support sleeves 8 respectively extend into the stirring tank 12, and mounting disks 5 are installed at the opposite ends of the two support sleeves 8. A plurality of support arms 2 are radially connected to the edges of the mounting disks 5. The support arms 2 are specifically installed on the edges of the mounting disks 5 through bolts, which facilitates the disassembly of the support arms 2. A plurality of mounting rods 3 are arranged in parallel around the outer periphery of the mounting shaft 1, and both ends of the mounting rods 3 are respectively connected to the support arms 2. As Figure 4 shown, a plurality of spaced stirring blades 4 are installed on the surface of each mounting rod 3. The stirring blades 4 are of a spiral structure, and the stirring blades 4 on adjacent two mounting rods 3 have opposite spiral directions.

[0038] A plurality of groups of first spiral blades 11 arranged at intervals along the mounting shaft 1 are provided on the mounting shaft 1. The number of each group of first spiral blades 11 is multiple, and each first spiral blade 11 is connected to the mounting shaft 1 through a plurality of support rods 9. In order to increase the acceleration and mixing efficiency, as Figure 3As shown in the figure, inside the space enclosed by each group of first helical blades 11, a plurality of second helical blades 10 are provided. The second helical blades 10 are also respectively connected to the support rods 9. In this way, the second helical blades 10 and the first helical blades 11 form an inner and outer structure, and the second helical blades 10 have a helical direction opposite to that of the first helical blades 11, and the adjacent two groups of first helical blades 11 have opposite helical directions.

[0039] Specifically, on the installation shaft 1, a stirring component is formed by the first helical blades 11 and the second helical blades 10, and on the installation rod 3, a stirring component is also formed by the stirring blades 4. The two stirring components are distributed inside and outside, and the inner and outer stirring components do not contact. During the actual stirring process, the support sleeve 8 and the installation shaft 1 are respectively connected to the driving mechanism, and the inner and outer stirring components rotate simultaneously. That is, the stirring blades 4 first shovel up the materials, and then the materials are stirred by the first helical blades 11, and then the materials are continuously stirred by the second helical blades 10. Since the first helical blades 11 and the second helical blades 10 are arranged in the opposite direction, and the stirring blades 4 are also of a helical structure, the materials roll over rapidly and irregularly under the simultaneous agitation of the inner and outer stirring components, and the fermented matter and the distiller's yeast can be quickly mixed. After the mixing is completed, the materials are discharged through the discharge port 20.

[0040] It should be noted that as Figure 1 shown in the figure, the support sleeves 8 at both ends of the stirring tank 12 are connected by a plurality of installation rods 3, so that the two support sleeves 8 are connected into a whole. When one support sleeve 8 is driven, the driving force will be transmitted to the other support sleeve 8 through the installation rod, so the two support sleeves 8 will rotate simultaneously.

[0041] The present application also proposes the detailed structure of the driving mechanism. As Figure 1 shown in the figure, the driving mechanism includes a support base 15 located below one end of the stirring tank 12. The support base 15 is connected to the support legs 16. For greater stability, the other end of the support base 15 also supports on the ground;

[0042] Specifically, a transmission box 13, a gearbox 14 and a driving motor 26 are provided on the support base 15. The driving motor 26 is connected to the transmission box 13 through the gearbox 14;

[0043] The transmission case 13 within this application has its particularity. It needs to meet the requirement that the internal and external stirring components operate synchronously and in opposite directions. The specific structure of the transmission case 13 includes a box body 25 installed on a support seat 15. On both sides of the box body 25, a first drive shaft 21 is rotatably provided. On the opposite ends of the two first drive shafts 21, a first bevel gear 22 is provided. There is a certain distance between the two first bevel gears 22. Within this distance, a second bevel gear 23 is provided. The two first bevel gears 22 are respectively meshed with the second bevel gear 23, and the second bevel gear 23 is arranged on a second drive shaft 24. The second drive shaft 24 is perpendicular to the first drive shaft 21 and the other end is rotatably installed on the side surface of the box body 25;

[0044] Among them, the second drive shaft 24 is connected to the transmission 14, and the transmission 14 is connected to the drive motor 26. Therefore, when the drive motor 26 rotates, the drive motor 26 transmits the power to the second bevel gear 23 after reducing the speed and increasing the torque through the transmission 14. Then the second bevel gear 23 drives the two second bevel gears 23 to rotate simultaneously, causing the two first drive shafts 21 to rotate in reverse coaxially;

[0045] As Figure 1 and Figure 2 shown, the connection relationship between the first drive shaft 21 and the support sleeve 8 and the mounting shaft 1 is that on one of the first drive shafts 21 and the support sleeve 8, a second pulley 7 is provided. The two second pulleys 7 are connected by a belt. On the other first drive shaft 21 and the mounting shaft 1, a first pulley 6 is provided. The two first pulleys 6 are connected by a belt. In this way, the mounting shaft 1 and the support sleeve 8 can be driven to move simultaneously by the first drive shaft 21.

[0046] Since the mixing amount of the koji is large, the small-volume stirrer can no longer meet the stirring requirement of the koji. Therefore, when the length span of the stirring tank 12 becomes larger to increase the stirring volume, the amount of materials at this time increases, making the movement resistance of the mounting rod 3 increase. In order to keep the mounting rod 3 stable and not deformed, as Figure 2 shown, a transmission shaft 17 is provided below the stirring tank 12. One end of the transmission shaft 17 is connected to the first drive shaft 21;

[0047] A plurality of connecting frames 18 are rotatably installed on the transmission shaft 17. The two ends of the connecting frame 18 are respectively connected to the support legs 16; on the end of the transmission shaft 17 far from the support seat 15 and on the end of the support sleeve 8 far from the support seat 15, a third pulley 27 is installed. The two third pulleys 27 are connected by a belt. In this way, when the drive motor 26 rotates, the two support sleeves 8 can be rotated simultaneously, making the forces on the two support sleeves 8 the same and ensuring that there is no stress difference on the mounting rod 3.

[0048] Based on the above embodiments, further optimization can be made. A protective cover 19 is provided at both the third pulley 27 and above the support base 15, and the protective cover 19 is respectively connected to the mixing tank 12 and the support base 15.

[0049] Based on the above embodiments, further optimization can be made. The first pulley, the second pulley, and the third pulley can be replaced with sprockets. Of course, the belt needs to be replaced with a corresponding drive chain.
