Description

Technical Field

[0001] This utility model relates to the field of sweet wine yeast production and processing technology, and in particular to a uniform inoculation device for fermented rice yeast. Background Technology

[0002] Sweet wine starter is mainly used in the production of sweet rice wine, where it serves as the primary fermentation agent. Its raw materials are primarily starchy ingredients such as glutinous rice, rice, and wheat, along with saccharifying bacteria. In the specific processing, the starchy ingredients need to be crushed and mixed, then pressed into shape, and finally inoculated with saccharifying bacteria for fermentation. The uniformity and quality of the inoculation process directly affect the quality of the subsequent fermentation.

[0003] Existing Chinese patent document CN202122123112.4 discloses a device for uniform inoculation of compound Chinese herbal medicine yeast. The device includes an inoculation base, which is a cuboid with a missing corner. A rotating inoculation disk is positioned above the missing corner of the inoculation base. The rotating inoculation disk is driven to rotate by a motor within the inoculation base. A fixed disturbance shaft is mounted on the rotating inoculation disk, passing through the bottom surface of the rotating inoculation disk and fixedly connected to the inoculation base. A disturbance rod extends parallel to the bottom surface of the rotating inoculation disk from the disturbance shaft. A disturbance plate, which is raised in the middle and has both ends attached to the bottom surface of the rotating inoculation disk, is located at the end of the disturbance rod. The tilted rotating inoculation disk causes the granulated rice balls to tumble inside. The fixed position of the disturbance plate and the raised shape of the middle cause relative movement between the lower rice balls and the disturbance plate, resulting in the rice balls tumbling and moving up and down within the disk. This combined movement of the rice balls continuously crisscrosses and rolls between the upper and lower layers, ensuring uniform inoculation of each rice ball and between rice balls.

[0004] Existing technology uses continuous rotation and stirring to ensure that the starch-based raw material balls of the single fermentation agent are fully inoculated with the inoculum. However, during the stirring process, due to the obliquely set rotating inoculation plate, the raw material balls will always roll downwards during the stirring process. If a large number of raw material balls are inoculated at one time, they are prone to falling to the ground. At the same time, the continuous downward movement can also cause the raw material balls to collide and become loose, which is extremely inconvenient. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a device for uniform inoculation of fermented glutinous rice yeast. The device rotates and stirs horizontally, keeping the raw material balls rolling evenly. This prevents them from colliding and loosening, and ensures that they come into full and even contact with the saccharifying bacteria. It also provides complete protection to prevent the raw materials from falling off. Combined with the rotation, the device evenly spreads the saccharifying bacteria for inoculation, making the inoculation more comprehensive and uniform, improving both the inoculation quality and efficiency. The device is flexible in operation, easy to load and unload, and provides stable and smooth processing. It is highly practical.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a uniform inoculation device for fermented rice wine yeast, including a base, a connecting shaft on the base, the connecting shaft being hinged to a first connecting piece at the bottom of the inoculation box, a connecting seat on the inoculation box, the connecting seat being hinged to a second connecting piece on the top cover, and an inoculation stirring structure and a feed inlet on the top cover.

[0007] The inoculation mixing structure includes a fixed base, which is connected to a rotating shaft via a connecting bearing. The top of the rotating shaft is provided with a first transmission wheel and a fixed frame. The first transmission wheel is connected to a second transmission wheel located on the output end of a drive motor via a transmission belt. The drive motor is fixedly connected to the top cover via a mounting frame. The fixed frame is provided with a spawn box. The discharge end of the spawn box is connected to one end of a guide pipe located in the center hole of the rotating shaft. The other end of the guide pipe is provided with multiple dispensing pipes. The dispensing pipes are inserted into the rotating shaft and are provided with multiple sprinkling heads. The base of the rotating shaft is provided with a rotating seat, and the rotating seat is provided with multiple sets of turning plates.

[0030] In a preferred embodiment, the bottom of the inoculation box 6 is fixedly equipped with an operating handle 7, and the inoculation box 6 is provided with a discharge groove 11 and a limiting installation groove 12. The limiting installation groove 12 is provided with a sealing plate 13 that is detached and assembled with it, and the sealing plate 13 is provided with a buckle plate 14.

[0031] In the preferred embodiment, the multiple sets of turning plates 31 are evenly arranged around the rotating base 30.

[0034] In a preferred embodiment, the rotating shaft 18 is provided with a limiting ring 19.

[0035] Example 2:

[0036] like Figure 1-3 In the middle, the inoculation box 3 is made of 304 stainless steel and has a volume of 5L. The bottom is hinged to the connecting shaft 4 of the base 1 through the first connecting piece 5, and can rotate around the shaft for easy unloading.

[0037] The drive motor 23 is a geared motor with a power of 0.75kW and a speed controlled between 15-30r / min;

[0038] The guide tube 27 in the center hole of the rotating shaft 18 is made of food-grade silicone material with an inner diameter of 8mm.
