Description

Technical Field

[0001] This invention relates to the field of coarse grain processing technology, and more specifically, to a method for high-value processing of coarse grains. Background Technology

[0002] Coarse grains generally refer to grain and legume crops other than the five major crops: rice, wheat, corn, soybeans, and potatoes. They are characterized by a short growing season, limited planting area, specific growing regions, and lower yields. They are generally rich in nutrients, including protein, fat, vitamins, minerals, and fiber. More importantly, they contain functional components with physiological benefits. For example, oats contain the functional component β-glucan, which has blood sugar and lipid-lowering effects; buckwheat contains the functional components rutin and quercetin, which also have lipid-lowering functions. Therefore, coarse grains have special therapeutic effects and hold an important position in modern safe and healthy food.

[0003] In reality, as people's living standards continue to improve, they not only pursue health but also require food to have a good taste. While whole grains have high nutritional value, their taste is not very good. Therefore, to make them easier for consumers to eat, manufacturers process whole grains into powder, making them more palatable. This is what is known as meal replacement powder. However, the following problems arise during the processing of meal replacement powder: the existing processing technology requires the use of a grinder to grind the whole grains, but this grinding method easily leads to the loss of nutrients in the whole grains, further affecting the processing effect of the meal replacement powder.

[0004] Therefore, we propose a high-value processing method for miscellaneous grains to solve the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a method for high-value processing of miscellaneous grains to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-value processing method for miscellaneous grains, comprising the following steps: Step S1: raw material cleaning, screening, washing and drying the miscellaneous grains; Step S2: raw material roasting, microwaving the cleaned miscellaneous grains from Step S1; Step S3: raw material powdering, feeding the roasted miscellaneous grains into a powdering device for powdering; Step S4: raw material drying, drying and pulverizing the raw materials containing moisture; Step S5: raw material sieving, sieving the dried raw materials; Step S6: raw material packaging, microwaving the sieved raw materials for sterilization, and then weighing and packaging them using an automatic packaging machine.

[0007] In this process, an ultrasonic generator is used to pulverize the grains, thus avoiding mechanical pulverization and further reducing nutrient loss during the pulverization process. At the same time, using ultrasound to pulverize the grains improves their texture and makes them more evenly mixed, reducing the need for mixing equipment and further lowering production costs, thereby indirectly improving the practicality of this production process.

[0008] In a preferred embodiment, the powder forming equipment includes a processing tank, on which multiple ultrasonic generators are fixedly connected. A motor is provided above the processing tank, and a stirring shaft is fixedly connected to the drive shaft of the motor. The lower end of the stirring shaft passes through the side wall of the processing tank and extends into the interior. Multiple air outlets are provided on the side wall of the stirring shaft.

[0009] In a preferred embodiment, a collar is fitted onto the stirring shaft, the collar and the stirring shaft are connected in communication, a sealed bearing is provided at the connection between the collar and the stirring shaft, an air inlet pipe is fixedly connected to the side wall of the collar and is connected to an external air source, a water inlet pipe is fixedly connected to the side wall of the collar and is connected to an external water source, and two bent rods connected to the treatment tank are fixedly connected to the side wall of the collar.

[0010] In a preferred embodiment, the cross-sectional area of ​​the plurality of air outlets is trapezoidal, and the diameter of the output end of the air outlet is smaller than the diameter of the input end of the air outlet.

[0011] In a preferred embodiment, in step S1, the grains include one or more of the following: pitted dried red dates, goji berries, black sesame seeds, walnuts, Job's tears, sorghum, millet, buckwheat, oats, and barley.

[0012] In a preferred embodiment, the speed of the motor is 1500 r / min to 2500 r / min.

[0013] In a preferred embodiment, the gas inlet velocity of the air inlet pipe is 4m / s-8m / s, and the water flow velocity of the water inlet pipe is 0.8m / s-4.8m / s.

[0014] In a preferred embodiment, in step S4, the drying temperature in the drying equipment is 120℃-180℃.

[0015] In a preferred embodiment, in step S5, the sieve mesh size is 120-160 mesh.

[0016] The technical effects and advantages of this invention are as follows:

[0017] In this process, an ultrasonic generator is used to pulverize the grains, thus avoiding mechanical pulverization and further reducing nutrient loss during the pulverization process. At the same time, using ultrasound to pulverize the grains improves their texture and makes them more evenly mixed, reducing the need for mixing equipment and further lowering production costs, thereby indirectly improving the practicality of this production process.
