Description

Technical Field

[0001] The invention relates to the technical field of grain germination, in particular to a brown rice germination machine and a germination method. Background Art

[0002] Brown rice is a natural grain that has not been finely ground after the rice grains are husked. It is rich in dietary fiber, vitamins and minerals, but the dense bran on the surface makes it difficult to cook and has a low digestion and absorption rate. Studies have found that by controlling the germination of brown rice, the internal enzyme system can be activated, and the content of active ingredients such as γ-aminobutyric acid (GABA) and B vitamins can be significantly increased. At the same time, the rice grain structure can be softened, and the taste and nutritional properties can be improved. Compared with ordinary brown rice, sprouted brown rice has richer nutrients, is easier to be absorbed by the human body, and tastes better. Therefore, sprouted brown rice has gradually become a research hotspot in the field of healthy food.

[0003] The patent with publication number CN119032844A in the prior art discloses a commercial germination device and a grain germination method. The commercial germination device includes a container for containing materials to be germinated, and a liquid supply device for providing liquid to the container; the container is configured to: be suitable for accumulating liquid so that the materials to be germinated can be soaked in the container; and be suitable for discharging liquid so that the soaked and moistened materials to be germinated can germinate in the container; the liquid supply device is configured to: during the process of soaking the moistened materials to be germinated for germination, provide liquid to the container so that the container accumulates liquid again to soak the materials to be germinated, so that the heat generated by the materials to be germinated during the germination process is dispersed by the liquid, so that the temperature of each part of the materials to be germinated is balanced.

[0004] The above-mentioned germination equipment adopts the immersion method to germinate grains, and there are the following problems during germination: 1. Grains are soaked in liquid for germination. When the liquid is filtered out after germination, the liquid will cause the loss of nutrients such as GABA; 2. The amount of water used in the grain soaking process is large, which easily causes a waste of water resources. Summary of the invention

[0005] The invention provides a brown rice germination machine and a germination method, which solve the problem in the prior art that nutrient loss and water waste may occur during soaking and germination of grains.
