Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquor brewing technology, specifically to a grain mixing equipment for liquor production. Background Technology
[0002] Baijiu is a distilled spirit made primarily from grains, using daqu, xiaoqu, bran koji, enzymes, and yeast as saccharification and fermentation agents, through processes such as cooking, saccharification, fermentation, distillation, aging, and blending.
[0003] The brewing process of baijiu includes selecting raw materials, making koji, steaming, mixing koji, fermentation, distillation, aging, blending, and bottling. Mixing koji involves mixing the koji into the steamed grains. The traditional method is to spread the steamed grains on the ground, then sprinkle the koji evenly on the grains, and then stir the grains multiple times to ensure that the koji and grains are fully mixed. This method is labor-intensive for workers and results in poor uniformity of koji mixing, which needs to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above difficulties and provide a grain mixing equipment for liquor production that can replace manual labor, has a fast mixing speed, and good uniformity.
[0006] (II) Technical Solution
[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a grain mixing equipment for liquor production, including a grain mixing drum, wherein a grain mixing device is provided inside the grain mixing drum;
[0008] The grain mixing device includes a motor located at the top of the grain mixing drum, the output end of the motor extending into the grain mixing drum and having a rotating shaft with spiral blades arranged around it.
[0009] The mixing drum is equipped with a grain guide tube that is sleeved on the spiral blades.
[0010] As an improvement, the bottom of the mixing drum is inverted conical, and a gate valve is provided at the bottom of the mixing drum, with the spiral blades positioned close to the gate valve.
[0011] As an improvement, the top of the grain mixing drum is provided with a plate, and the motor is mounted on the plate.
[0012] As an improvement, the grain guide cylinder is provided with several connecting rods that are fixedly connected to the grain mixing cylinder.
[0013] (III) Beneficial Effects
[0014] The advantages of this utility model compared with the prior art are as follows:
[0015] 1. The motor on the grain mixing device drives the rotating shaft and spiral blades to rotate, stirring the grain and ensuring that the grain and yeast are fully mixed.
[0016] 2. The grain guide cylinder is arranged around the grain mixing device, so that the grain mixing device can quickly turn the grain at the bottom of the grain mixing cylinder upwards and the grain at the top moves from the outside of the grain guide cylinder to the bottom of the grain mixing cylinder, so that the grain and yeast are fully mixed.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0023] Example 1
[0024] Combined with appendix Figure 1-4 A grain mixing equipment for liquor production includes a grain mixing drum 1, wherein a grain mixing device 2 is provided inside the grain mixing drum 1;
[0025] The grain mixing device 2 includes a motor 3 located at the top of the grain mixing drum 1. The output end of the motor 3 extends into the grain mixing drum 1 and is provided with a rotating shaft 4. A spiral blade 5 is arranged around the rotating shaft 4. The motor 3 drives the rotating shaft 4 and the spiral blade 5 to rotate, which can turn the grain at the bottom of the grain mixing drum 1 upward. The worker sprinkles the yeast from the top of the grain mixing drum 1 onto the grain. The yeast adheres to the grain as it is turned up and down.
[0026] The mixing drum 1 is equipped with a grain guide tube 6 sleeved on the spiral blades 5. The grain guide tube 6 can guide the turning of the grain, so that the grain at the bottom turns upward and the grain at the top moves downward through the outside of the grain guide tube 6, so that the grain and the yeast are fully mixed.
[0027] The bottom of the mixing drum 1 is inverted cone shape, and a gate valve 7 is provided at the bottom of the mixing drum 1. The spiral blades 5 are located near the gate valve 7, which can make the grain fully mixed.
