Description

Technical Field

[0001] The invention relates to the field of liquor brewing, and in particular to a koji mixing device for liquor brewing. Background Art

[0002] Liquor brewing refers to the process of converting raw materials such as grain into liquor through specific processes and methods, which includes raw material selection, steaming, cooling, mixing koji, fermentation, distillation, aging and other processes. The mixing koji is to evenly sprinkle the koji into the cooled raw materials and stir it thoroughly to evenly distribute the active ingredients of the koji to ensure the quality of liquor brewing.

[0003] Most of the existing koji mixing devices for liquor brewing place both liquor brewing raw materials and koji in the koji mixing device, and then stir and mix them. The amount of koji added is about 1% to 3% of the weight of the raw materials, that is, when 100 kg of raw materials are used, 1 to 3 kg of koji can be added. If both liquor brewing raw materials and koji are placed in the koji mixing device, and the koji is randomly sprinkled on the surface of the liquor brewing raw materials, it will take more time to evenly mix the liquor brewing raw materials and koji. This is because a small part of the raw materials is exposed to more koji, while other parts are exposed to less, which affects the koji mixing efficiency.
