Description

Technical Field

[0001] The utility model relates to the technical field of germinated brown rice preparation, in particular to a production device for germinated brown rice nutritional powder. Background Art

[0002] Sprouted rice is made from brown rice, which has been treated with a physiological activation process and germinated to a certain length. This method avoids the drawbacks of brown rice, such as cooking, poor taste, and poor digestibility. After germination, the bran fibers of the brown rice soften, and some of the protein breaks down into amino acids and starch into carbohydrates, improving the sensory properties and flavor of the food. Compared to brown rice, sprouted brown rice contains a richer variety and content of functional ingredients. Generally, the γ-aminobutyric acid content in sprouted brown rice is approximately 10 times that of regular rice; the inositol hexaphosphate content is over four times that of white rice; and the dietary fiber content is 3.7 times that of polished white rice. Furthermore, sprouted brown rice is rich in a variety of active substances with special physiological functions, such as glutathione, ferulic acid, phytic acid, oryzanol, tocotrienols, phytosterols, tetracosanol, and octacosanol. These substances have numerous health benefits, including reducing the incidence of cardiovascular and cerebrovascular diseases, preventing digestive tract cancers, and anti-aging (Yao Miaoai, Food Industry, Vol. 35, No. 1, 2014).

[0003] Parboiled rice contains high levels of nutrients beneficial to the human body. For example, its vitamin B1 and vitamin B2 content is nearly 3–4 times that of regular rice, its crude fat content is 1–2 times that of regular rice, its protein content is also much higher, and its calcium, phosphorus, and iron content are nearly 2–3 times that of regular rice. This may be due to the fact that during the soaking process, some water-soluble nutrients diffuse into the soaking liquid. As the soaking time increases, they enter the rice endosperm, where they are retained during processing, thereby increasing the nutritional value of the rice. Soaking not only increases the content of water-soluble nutrients, but also improves the color and heavy metal content of the parboiled rice through different soaking liquids. Furthermore, a series of hydrothermal treatments make the nutrients in parboiled rice more readily absorbed by the human body. Furthermore, during cooking, the rice yield is high, the rice expands well, the rice grains do not stick together, and they have a unique aroma and are easily digestible (Wu Fang, A Comprehensive Overview of Parboiled Rice, Modern Food).

[0004] Since germinated brown rice has a high nutritional value, many companies have launched commercial germinated brown rice. The process technologies used are basically traditional technologies, including the process from rice to hulling (brown rice), soaking, germination, and drying. The process of parboiled rice is obtained by rice, soaking, drying, and rice milling. Germinated brown rice is made from brown rice, which is made from rice. During the production process from rice to brown rice, the endosperm and bran fiber membrane are mechanically damaged, causing some brown rice to lose its germination ability during the production of germinated brown rice. In addition, during the soaking and germination of brown rice, nutrients penetrate into the soaking liquid through the bran fiber layer, causing nutritional loss and producing odor that has an adverse effect on the germinated brown rice. It also has disadvantages such as high water consumption. In addition, the current technology and equipment require large investment, large floor space, and low production efficiency. Based on this, the utility model proposes a production device for germinated brown rice nutritional powder. Utility Model Content

[0029] like Figure 1 As shown, a production device for germinated brown rice nutritional powder includes a main body 1, a water tank 2 is installed at the bottom of the main body 1, and the water tank 2 is a funnel-shaped structure. A plurality of supporting plates 5 are rotatably installed at equal intervals in the vertical direction inside the main body 1.

[0030] In this embodiment, Figure 2 As shown, the support plate 5 includes a support rod 503 fixed between the inner side walls of the main body 1. Several pneumatic telescopic rods 504 are hingedly connected to the support rod 503, and the pneumatic telescopic rods 504 are symmetrically distributed on both sides of the support rod 503. The other ends of the pneumatic telescopic rods 504 are hingedly connected to the first plate 501 and the second plate 502. The first and second plates 501 and 502 are connected together by a hinge. The pneumatic telescopic rods 504 are activated to retract via a pneumatic valve 505. Specifically, by adjusting the telescopic state of the pneumatic telescopic rods 504, the opening and closing angles of the first and second plates 501 and 502 can be adjusted directly. When the opening and closing angle is zero, the rice can be lifted. As the opening and closing angle gradually increases, the first and second plates 501 and 502 tilt downward, causing the rice to fall under its own weight. The support plate 5 is provided with a plurality of small holes. Specifically, the number of the support plates 5 is 5-40, and the gaps between the small holes are 2-3 mm.

[0031] like Figure 3 As shown, atomizing nozzles are installed on the inner wall of the main body 1 between adjacent supporting plates 5. The atomizing nozzles are connected together by serpentine pipes. The serpentine pipes are distributed on the inner wall of the main body 1. The atomizing nozzles are equidistantly installed on the serpentine pipes, and the nozzle directions of the atomizing nozzles are distributed inwardly to realize the spraying operation of the rice on the supporting plate 5.

[0032] A hollow interlayer 4 is mounted on the outer wall of the main body 1. This interlayer 4 is connected to a hot and cold water tank 11 via a circulation pipeline. A stirring device 12 is installed within the hot and cold water tank 11. A circulating water pump 13 and a check valve 15 are installed in the circulation pipeline between the interlayer 4 and the hot and cold water tank 11. Specifically, the cold / hot water in the hot and cold water tank 11 rises from the bottom of the interlayer 4 to the top before flowing back into the hot and cold water tank 11 through the circulation pipeline. This cycle repeats, achieving the functions of heat preservation, heating, or cooling.

[0033] The top of the main body 1 is equipped with a circulating fan 6 and an exhaust port 7, with an exhaust valve installed on the exhaust port 7. The bottom of the water tank 2 is connected to a six-way pipe 17 through a pipeline. The other end of the circulating fan 6 is connected to a circulating water pump 2 14 through a pipeline and the six-way pipe 17. The other end of the circulating water pump 2 14 is connected to a pipeline connected to the atomizing nozzle. Specifically, by activating the circulating water pump 2 14, the circulating fan 6, and the atomizing nozzle, water vapor is circulated within the main body 1, using circulating atomization to re-moisten the rice, replacing the soaking method and preventing nutrient loss and odor.

[0034] The six-way pipe 17 is connected to the flash generator 16, the heating box 10, and the rice huller 18. The flash process heats the rice rapidly and evenly, preventing some rice grains from over-ripening and aging, and turning into cooked rice. The other end of the heating box 10 is connected in sequence to a high-efficiency filter 9 and a purification fan 8. The use of purified air keeps the germination environment free of microbial contamination, ensuring germination rate and nutritional purity. The other end of the rice huller 18 is connected to a bran-rice separator 19 and a rice mill 20, which are connected via pipelines.

[0035] A feeding door 3 is provided on the side wall of the main body 1 .

[0036] In addition, solenoid valves are installed on the pipelines connected by the six-way pipe 17, the circulation pipeline, the connecting pipeline between the rice husker 18 and the rice-bran separator 19, and the connecting pipeline between the rice husker 18 and the rice mill 20. A temperature sensor, a humidity sensor, and a carbon dioxide gas detector are also installed inside the main body 1. During actual operation, the operator controls the operation of each component according to the detected parameters such as temperature, humidity, and carbon dioxide concentration through the PLC control program according to actual needs until the desired germinated brown rice nutritional powder is obtained.
