Description

Technical Field

[0001] The invention relates to the technical field of fermentation and brewing equipment, in particular to a koji-making device used for material fermentation and brewing. Background Art

[0002] Daqu (or "big koji"), also known as block koji or brick koji, is a raw material used in brewing. Made from ingredients such as barley, wheat, and peas, it is ground, kneaded with water, and pressed into a mash (or fermented mash) resembling bricks of varying sizes. This mash allows a variety of naturally occurring microorganisms to grow within it. Each step in the koji-making process requires specific control points. Failure to properly control these key points results in substandard daqu that cannot be used for brewing. Only high-quality koji can produce high-quality liquor. The kneading and mixing steps of fermentation and brewing involve mixing the ingredients. This mixing process involves both batching and stirring, and the ingredients are generally not a single ingredient. For example, in wheat-based koji, some beers incorporate 3%-5% of koji powder from the previous batch. When using barley, peas, and wheat together, the three grains are ground, mixed in varying proportions, and then stirred. Mixing can be done manually or mechanically.

[0003] In the prior art, in order to improve work efficiency, factories often use mechanical mixing to prepare large-scale fermentation and brewing of materials. Conventional mechanical mixing equipment often only stirs by a stirring rod and cannot stir by changing the position up and down. It is easy to cause upper and lower stratification and affect the stirring effect. In order to improve this, it is necessary to design a koji-making device for material fermentation and brewing.

[0050] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0051] See also Figure 1-6 , a koji-making device for material fermentation and brewing, comprising:

[0052] A material mixing barrel 1 is provided with a barrel cover 2, so that in the material mixing process during the fermentation and brewing of the material, the material and water are put into the material mixing barrel 1 and the barrel cover 2 is used to seal the barrel for stirring;

[0053] The rotating shaft 3 extends into the material mixing barrel 1 through the barrel cover 2;

[0054] A conical stirring head is provided on one end of the rotating shaft 3 and extends into the material stirring barrel 1 and rotates along with the rotating shaft 3;

[0056] A rotation drive mechanism, which is provided on the lifting bracket to drive the rotating shaft 3 to rotate axially;

[0057] The lifting drive mechanism is provided on one side of the material mixing barrel 1 to drive the rotating shaft 3 to move up and down in the vertical direction through the support of the lifting bracket, so that the rotating shaft 3 and the cone stirring head can be driven by the rotating drive mechanism to rotate to stir the material while performing the lifting movement, thereby achieving up and down stirring and avoiding stratification or incomplete stirring.

[0058] A water filling tap 4 is connected to an external water pipe to draw water. A notch 5 is provided on the upper end of the material mixing barrel 1 to accommodate the water filling tap 4 for convenient water filling.

[0059] A blocking clamping mechanism is provided on the water filling tap 4 to clamp and fix the water filling tap 4 in the notch 5 and block the notch 5 to prevent the material from overflowing from the notch 5;

[0060] When the rotating shaft 3 drives the cone stirring head to move upward, the cone stirring head is deformed into a cone with the cone surface facing upward; when the rotating shaft 3 drives the cone stirring head to move downward, the cone stirring head is deformed into a cone with the cone surface facing downward.

[0061] In summary, this device stirs the material by driving the conical stirring head in an upward and downward motion. When the rotating shaft drives the conical stirring head upward, the conical stirring head deforms into a cone with the cone facing upward to stir the material; when the rotating shaft drives the conical stirring head downward, the conical stirring head deforms into a cone with the cone facing downward to stir the material. This can better drive the flow of upper and lower layers of material, improve the stirring effect, and avoid stratification during the stirring process. The better stirring effect also greatly improves stirring efficiency, thereby enhancing the working efficiency of the koji-making equipment for material fermentation and brewing.

[0062] Furthermore, the bottom surface of the material mixing barrel 1 is an inclined bottom surface.

[0063] Furthermore, a discharge pipe 6 is provided at the lower end of the material mixing barrel 1 , and the inclined bottom surface of the bottom of the material mixing barrel 1 guides the material to flow into the discharge pipe 6 .

With the cone facing the direction of movement, it can better drive the flow of materials during the stirring process, and then realize stirring between the upper and lower layers. The same applies to the downward movement of the rotating shaft 3.

[0074] Furthermore, the lifting bracket includes a longitudinal rod 20 and a transverse rod 21, and the longitudinal rod 20 and the transverse rod 21 are vertically connected;

[0088] Specifically, before placing the water filling tap 4 in the notch 5, pull the pull handle 37 so that the sliding ring 36 is driven away from the inner anti-blocking piece 35 through the arc-shaped push rod 38. At this time, the water filling tap 4 can be placed in the notch 5. The sliding ring 36 and the inner anti-blocking piece 35 are respectively located on both sides of the notch 5. Then release the pull handle 37. Under the action of the restoring force of the compression spring 40 on the fixed block 39, the pulling handle 37 is pushed to return to the initial position. Then, the sliding ring 36 is pushed and pressed against the material mixing barrel 1 through the arc-shaped push rod 38. Then, the sliding ring 36 and the inner anti-blocking piece 35 are clamped on the material mixing barrel 1, thereby completing the fixation of the water filling tap 4, making it convenient to inject clean water at any time and improving work efficiency.
