Description

Technical Field

[0001] This invention is applied to the field of health product manufacturing, specifically relating to the production of wheat selenium peptide nutritional products, and is a key rotating component for separating the buds and roots of malt. Background Technology

[0002] Selenium-enriched wheat peptides, a selenium-containing nutritional supplement, are manufactured using black wheat as the raw material. Black wheat is cultured in a selenium-enriched nutrient solution to produce high-selenium malt. The malt sprouts and roots are then separated. The malt sprouts with higher water content are pulverized into nano-sized fine powder using an angle grinder, and then dried and sterilized to produce the selenium-enriched wheat peptide nutritional supplement. It is difficult to pulverize dried malt sprouts into nano-sized particles; therefore, separation of the sprouts and roots can only be achieved while the sprouts are still moist. Currently, there is no ideal separation equipment for malt. The applicant uses a double-roller extrusion separation method, which can achieve separation of the sprouts and roots, but has two drawbacks: first, the liquid nutrients within the sprouts are lost after extrusion; second, after separation, the roots and sprouts remain entangled, only achieving separation, requiring further drying and separation. Under moist conditions, the sprouts absorb water, causing cell swelling, filling the gaps with water, and significantly increasing density to 1.1–1.3 g / cm³. The root structure is fine and relatively dense, and its density increase after water absorption is less than that of the bud. The wet density is 0.8–1.0 g / cm³, and the separation effect can be enhanced by mechanical rubbing. Guided by this concept, this utility model seeks commonly used equipment in production and innovates its structure to meet the requirements of malt separation.

[0003] No patents were found for devices or components specifically used for separating buds and roots of malt. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a rotating component for malt separation, which can knead malt on the water surface to separate it, and stir the water in the water to separate the buds and roots, thus creating conditions for the separation of the two.

[0005] The technical solution adopted in this utility model is as follows: The rotating component for malt separation includes a rotating shaft and helical blades fixed on the rotating shaft. The rotating shaft consists of a front shaft and a rear shaft connected together; the rear shaft is a semi-hollow shaft with a blind hole machined in its center and a small hole machined on its outer surface, the blind hole communicating with the outside through the small hole. During installation and use, the small hole is located below the water surface. The helical blades include separating blades and peeling blades, the separating blades are fixed on the front shaft with a consistent pitch, and the outer surface of the separating blades is covered with a coating; the peeling blades are fixed on the rear shaft.

[0006] Furthermore, to enhance the kneading ability of the separated screw blades, protrusions or rings are provided on the surface of the separated screw blades.

[0007] Furthermore, to enhance the stirring effect of the stripping screw blades on water, protrusions are provided on the surface of the stripping screw blades.

[0008] Furthermore, the connection between the front and rear axles can be a fixed integral connection or a universal coupling connection. The front axle can drive the rear axle to rotate, and different connection methods can be selected as needed.

[0009] Furthermore, the front axle is connected to the power unit, and the rear axle is connected to the air pipe through a hollow component to introduce air into the water and enhance the stirring of the water.

[0010] The beneficial effects of this utility model are: the front shaft and the separating spiral blades promote the separation of the bud and the root by kneading the malt, and the rear shaft and the separating spiral blades achieve the separation of the two by stirring the water. The bud is subjected to less pressure, which protects the liquid nutrients in the bud and prepares for the separation of the two, thus simplifying the malt separation process.

Detailed Implementation

[0012] The term "separated" refers to a state where the bud and roots are no longer integrated but still intertwined; "peeled" means the bud and roots are no longer intertwined; and "separated" means the bud and roots occupy their own space. The term "roots" includes the husk that is integrated with the roots. The term "front and back" refers to the direction of malt movement; the malt moves from front to back, that is, the attached... Figure 1 and attached Figure 2 The left side is "front" and the right side is "rear". The "shaft end" below refers to the free end of the front and rear axles, which are connected in the middle, that is, the front end of the front axle and the rear end of the rear axle.

[0013] The accompanying drawings are explanations and illustrations of the structure of this utility model. Some structures, such as the seal and power transmission, are existing technologies and are not described in detail. Example 1

[0014] The structure of the rotating component in this embodiment is shown in the attached figure. Figure 1 As shown, the device includes a rotating shaft and helical blades. The helical blades are fixedly mounted on the rotating shaft, and their helical direction causes the shaft to rotate, propelling the malt. The rotating shaft consists of a front shaft 1 and a rear shaft 2. In this embodiment, the front shaft 1 and the rear shaft 2 are a fixedly connected integral structure (the cross-sectional view shows the rear shaft). The front shaft mainly operates above the water surface, while the rear shaft is submerged below the water surface. The front shaft is a solid shaft, and the rear shaft is a semi-hollow shaft. A blind hole 24 is machined in the center of the rear shaft, and a small hole 23 is machined on its outer surface. The small hole is a through hole, and the blind hole 24 communicates with the outside through the small hole 23.

[0015] The spiral blades include a separating spiral blade 11 and a peeling spiral blade 21. The separating spiral blade 11 is fixedly mounted on the front shaft 1 with a uniform pitch, while the peeling spiral blade 21 is fixedly mounted on the rear shaft 2. To prevent corrosion in water or humid conditions, the spiral blades should preferably be made of stainless steel. The main function of the separating spiral blade 11 is to knead and separate the buds and roots of the malt. As the shaft drives the spiral blades to rotate, the separating spiral blades rub, knead, and squeeze the malt, causing the buds and roots to separate. At this point, the separated roots are entangled on the surface of the buds, making separation impossible. The main function of the peeling spiral blade 21 is to peel the roots entangled on the buds. The peeling spiral blade 21 rotates in water, as shown in the attached image. Figure 2 As shown, the water is stirred, and by utilizing the density difference between the bud and the roots, as well as the stirring effect of the water, the roots entangled on the bud are separated from the bud, preparing for the subsequent separation of the two.

[0016] To prevent the loss of liquid nutrients in the malt, the squeezing action should be reduced and the friction and kneading enhanced during malt separation. Stainless steel has a smooth surface and a low coefficient of friction. A coating 12 is provided on the outer surface of the separating screw blade 11. The coating 12 can be a plastic or metal coating, made through processes such as adhesion or spraying. Its main function is to increase the coefficient of friction while ensuring hygiene. When the screw blades have a consistent pitch, the squeezing action on the malt is relatively stable, without sudden changes in squeezing force. This enhances the kneading and separating action of the malt by increasing friction. To further enhance friction and kneading, protrusions 13 or rings can be added to the surface of the separating screw blade 11. The protrusions 13 or rings can be fixed integrally with the metal screw blades, and then coated or sprayed to form the protrusion or ring structure on the screw blade surface.

[0017] A protrusion 22 is provided on the surface of the stripping screw 21. The protrusion 22 rotates with the rotation of the stripping screw 21 to enhance the stirring effect on the water.

[0018] When using this embodiment, as shown in the attached document... Figure 2As shown, the rotating component is placed in an inclined tank 4. The shaft end of the front shaft 1 is connected to the power unit 3, and the shaft end of the rear shaft 2 is connected to the hollow component 5. The hollow component 5 is connected to the air pipe 6. Water is injected into the tank 4, and the water level is adjusted to submerge the rear shaft. The power unit 3 is started, driving the rotating component to rotate. After malt is added, the malt buds and roots separate under the kneading action of the separating screw 21, and then enter the water. Under the action of water buoyancy, the friction experienced by the malt is greatly reduced. While the separating screw 21 stirs the water, compressed air is introduced into the air pipe 6. The compressed air enters the blind hole 24 through the hollow component 5, and then passes through the small hole 23 into the water. As the air bubbles float in the water, the stirring of the water is also enhanced. The stirred water acts on the buds and roots, promoting the detachment of roots from the buds. Then, it enters the relatively still water area at the rear of the tank. Under the action of buoyancy, the roots float up and are carried out by the water flow, while the buds sink to the bottom of the tank, thus achieving the separation of the buds and roots. Example 2

[0019] The structure of the rotating component in this embodiment is shown in the attached figure. Figure 3 As shown, the device includes a rotating shaft and helical blades fixedly mounted on the shaft. The rotating shaft consists of a front shaft 1 and a rear shaft 2, connected by a universal coupling 7. The end of the front shaft is positioned and connected to the power unit, with the connection end positioned by a support plate 8. Driven by the power unit, it can rotate smoothly, enhancing friction and preventing squeezing and fluctuation. The helical blades include separating blades and peeling blades. The separating blades are fixedly mounted on the front shaft with a consistent pitch, while the peeling blades are fixedly mounted on the rear shaft. The blind holes and small holes in the rear shaft have the same structure.

[0020] When using this embodiment, as shown in the attached document... Figure 4 As shown, the front shaft 1 is installed horizontally in the separating groove, and the rear shaft 2 is installed at an angle in the peeling groove. Flowing water is added to the peeling groove, with the water level below the bottom of the separating groove. The malt is not affected by water during kneading in the separating groove. Compared to Example 1, this embodiment has the following advantages: 1) The separating groove can be appropriately shortened, reducing the manufacturing cost of the separating screw; 2) Using a universal coupling, the rear shaft 2 in the peeling groove can be arranged at multiple angles, facilitating the design of the peeling groove. The main function of the rear shaft is to agitate the water; its rotational stability and consistency with the front shaft are negligible.

[0021] The connection between the front and rear axles is not limited to the fixed connection and universal coupling connection in the above embodiments; any existing technology connection that can satisfy the requirement of the front axle driving the rear axle to rotate is acceptable. The rear axle shaft end may not use a hollow component to connect the air pipe, but instead uses a support plate to position the shaft end and connect a flexible air pipe at the shaft end.

[0022] This utility model relates to a key component for separating malt buds and roots. It is an improvement upon the main components of a screw feeder, representing an application of existing technology in a new field. The front shaft is a solid shaft with high torsional strength, meeting the requirements for power transmission during kneading and extrusion. The rear shaft primarily handles water agitation and does not require high torsional strength, so a hollow shaft can be used. This structural feature not only meets the separation process requirements but also satisfies the power transmission needs.

[0023] This invention utilizes the kneading action generated by the spiral blades to promote the separation of the bud and the roots, and uses agitated water to achieve the separation of the two, thus protecting the liquid nutrients in the bud and preparing for the separation of the two, and simplifying the malt separation process.
