Description

Technical Field

[0001] The invention relates to the technical field of rice bran nutrient extraction, in particular to a device for extracting natural nutrients from rice. Background Art

[0002] The rubber rollers of the rice mill squeeze the rice husks to obtain brown rice, and the rice bran is separated by mechanical squeezing and scraping. The dietary fiber nutrients in the rice bran are extracted, and the rice bran natural nutrients are extracted. The rice bran roller mill is a mechanical equipment specially used to finely grind the rice bran, a by-product of rice processing, and retain its natural nutrients. It adopts a roller grinding system to extrude, shear and rub the rice bran through multiple sets of high-speed rotating metal or ceramic grinding rollers to achieve fine grinding. The spacing between the grinding rollers is adjustable to meet different particle size requirements. At the same time, it is equipped with a screening device to separate coarse particles to ensure the uniformity of the powder. Rice bran powder is added to flour, baked goods (such as bread, biscuits) or beverages to increase the dietary fiber and mineral content. It is used to produce high-fiber meal replacement powder, cereal nutrition bars and other healthy foods, and convert rice bran, a by-product of rice processing, into high value-added products, reducing environmental pollution and promoting a circular economy.

[0003] The germ powder and rice bran powder granules ground by the existing rice bran natural nutrient roller mill are mixed together. The germ powder and the rice bran powder granules have similar diameters, which makes it inconvenient to screen and separate them, and it is inconvenient to further extract the dietary fiber nutrients of the rice bran. The germ powder is rich in oil and protein, while the rice bran fiber mainly exists in the rice bran powder granules. After mixing, the oil will wrap the surface of the rice bran powder granules, hindering the penetration of the solvent, resulting in a decrease in the dietary fiber extraction rate. In the mixed powder, the fat-soluble components of the germ are dissolved in the fiber extract, reducing the purity of the target product. The oil residue provides a nutrient base for microbial reproduction. If it is not thoroughly sterilized, the mixed powder is prone to mold growth and toxin pollution. Summary of the Invention

[0015] Beneficial effects

[0016] The present invention has the following beneficial effects:

[0017] (1) The device for extracting natural nutrients from rice grains uses an arched surface to evenly disperse germ powder and rice bran powder particles along the curved surface when the materials are dropped, thereby avoiding local accumulation and promoting the dissociation of germ powder agglomerates wrapped in oil. Furthermore, by supplying a 20KV DC point to the electric wire, the titanium alloy positive plate serves as a corona electrode, polarizing the surrounding air molecules through ionization. The germ powder particles preferentially obtain negative charges in the ionization field due to the oil content. Under the action of the electric field force, the negatively charged germ powder particles will be deflected and adsorbed toward the titanium alloy positive plate. The aluminum negative plate serves as a dust collecting electrode, and the residual negative charge on the surface forms an electrostatic adsorption field. The positively charged rice bran powder particles will migrate toward the aluminum negative plate, thereby automatically separating the germ powder and rice bran powder particles.

[0018] (2) The device for extracting natural nutrients from rice grains is configured to move the germ powder and the rice bran powder particles in different directions respectively by means of the arched sieve plate, and the germ powder and the rice bran powder particles fall into the sieve plate 1 and the sieve plate 2 respectively through the arched surface. The baffle plate prevents the germ powder and the rice bran powder particles from overflowing. The sieve plate 1 and the sieve plate 2 are 80-mesh sieves and 100-mesh sieves respectively, so that the germ powder flows from the sieve plate 1 into the feed trough 1. The arched sieve plate drives the sieve plate 1 and the sieve plate 2 to vibrate synchronously through the reciprocating linear motion. The periodic vibration destroys the adsorption balance between the particles and the sieve, and reduces the risk of the germ powder adhering to the sieve plate 1. The rice bran powder particles are accelerated to pass through the 100-mesh sieve on the sieve plate 2, and the germ powder falls into the feed trough 1 along a parabolic trajectory. The rice bran powder particles are vertically screened to the feed trough 2, forming automatic separation, thereby further facilitating the extraction of rice bran dietary fiber nutrition.

[0019] (3) The device for extracting natural nutrients from rice grains performs a stable reciprocating swinging motion through a long sieve plate. The long sieve plate is a 40-mesh screen, which is convenient for blocking seed coat fibers and rice husk fragments. Germ powder and fine-grained rice bran powder can pass through the long sieve plate, and the long sieve plate is tilted and reciprocatingly swung. The fan is working, and the fan blows the long sieve plate to facilitate the cleaning of fine dust. The 40-mesh screen of the long sieve plate effectively intercepts rice husk fragments and seed coat fibers, while allowing germ powder and fine-grained rice bran powder to pass through, forming a preliminary classification. The long sieve plate is tilted and combined with reciprocating swing, using gravity and inertia to promote material stratification, reducing the risk of clogging of the long sieve plate screen. The fan blows air in the same direction as the sieve plate movement, removing fine dust in time and avoiding cross contamination.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

In addition, a ceramic plate 21 is installed in the middle of the arched sieve plate 20, and a non-uniform electric field is formed on the surface of the arched sieve plate 20. The positive and negative electric field lines formed between the titanium alloy positive plate 22 and the aluminum negative plate 23 are densely distributed in the raised area, which enhances the force on the charged particles. The high resistance of the germ powder, Weak conductivity is more significantly deflected in a strong electric field area. The titanium alloy positive plate 22 acts as a corona electrode, polarizing the surrounding air molecules through ionization. The germ powder particles preferentially obtain negative charges in the ionization field due to the oil content. Under the action of the electric field force, the negatively charged germ powder particles will be deflected and adsorbed toward the titanium alloy positive plate 22. The aluminum negative plate 23 acts as a dust collecting electrode, and the residual negative charge on the surface forms an electrostatic adsorption field.

The interior of the roller mill 1 is mounted with a fixed sleeve 1 3. An annular groove 14 is provided on the outer surface of the transmission shaft 12. Two annular sliders 15 are movably mounted on the inner wall of the annular groove 14. A connecting plate 16 is mounted on the outer surface of the two annular sliders 15. A guide post 17 is mounted on the outer surface of the connecting plate 16. The outer surface of the guide post 17 is in movable contact with the inner surface of the fixed sleeve 13.

The sieve plate 1 2003 and the sieve plate 2 2004 are 80 mesh and 100 mesh screens respectively, so that the germ powder can be removed from the sieve plate 1 2 003 flows into the feeding trough 1 26, so that the rice bran powder granules flow from the sieve plate 2 2004 into the feeding trough 2 27, and the arched sieve plate 20 drives the sieve plate 1 2003 and the sieve plate 2 2004 to move back and forth linearly, thereby facilitating the feeding of germ powder and rice bran powder granules. The germ powder and the rice bran powder granules are subjected to the combined action of the electrostatic field force and the mechanical vibration on the surface of the arched sieve plate 20, forming a differentiated motion trajectory, thereby separating the germ powder and the rice bran powder granules for material extraction. Adjustable height baffles 2002 are installed on both sides of the sieve plate to effectively block the particle side To ensure the cleanliness of the separation process, the arched sieve plate 20 drives the sieve plate 1 2003 and the sieve plate 2 2004 to vibrate synchronously through the reciprocating linear motion. The periodic vibration destroys the adsorption balance between the particles and the screen, reducing the risk of the germ powder adhering to the sieve plate 1 2003, so that the rice bran powder particles are accelerated to pass through the 100-mesh screen on the sieve plate 2 2004, and the germ powder falls into the discharge trough 1 26 along a parabolic trajectory, while the rice bran powder particles are vertically screened to the discharge trough 2 27, forming automatic separation, thereby further facilitating the extraction of rice bran dietary fiber nutrition.

Germ powder and fine-grained rice bran powder can pass through the long sieve plate 7, and the long sieve plate 7 is tilted and swung back and forth, and the fan 25 is working. The fan 25 blows the long sieve plate 7 to facilitate the cleaning of fine dust. The long sieve plate 740-mesh screen effectively intercepts rice husk fragments and seed coat fibers, while allowing germ powder and fine-grained rice bran powder to pass through to form a preliminary classification. The long sieve plate 7 is tilted and combined with reciprocating swing, using gravity and inertia to promote material stratification and reduce the risk of clogging of the long sieve plate 7. The fan 25 blows air in the direction of the sieve plate movement to remove fine dust in time and avoid cross contamination.

[0036] The working process of the present invention is as follows: the rice husk of the rice is squeezed by the rubber roller of the rice mill to obtain brown rice, and the rice bran is separated by mechanical squeezing and scraping, so that the dietary fiber nutrition of the rice bran inside the rice bran needs to be extracted, and the rice bran raw material is added to the roller mill 1. After the raw material is processed and ground, rice husk fragments, seed coat fiber, germ powder, fine-grained rice bran powder and fine dust are generated, wherein the germ powder contains oil and fat, which falls onto the elongated sieve plate 7 through the guide plate 28. When the roller mill 1 is working, the motor 2 is synchronously powered and works, and the motor 2 drives the rotating shaft 3 to rotate slowly, and the rotating shaft 3 drives the eccentric crank 4 to rotate, and the eccentric crank 4 drives the crank rod 5 and the connecting column 6 to reciprocating swing motion, and the connecting column 6 drives the elongated sieve plate 7 to reciprocating swing motion, and the elongated sieve plate 7 drives the four The connecting rod 8 is deflected, so that the long sieve plate 7 can perform a stable reciprocating swinging motion. The long sieve plate 7 is a 40-mesh screen, which is convenient for blocking the seed coat fiber and rice husk fragments.

The 40-mesh screen of the long sieve plate 7 effectively intercepts rice husk fragments and seed coat fibers, while allowing germ powder and fine-grained rice bran powder to pass through, forming a preliminary classification. The long sieve plate 7 is tilted and combined with reciprocating swing, using gravity and inertia to promote material stratification and reduce the risk of clogging of the long sieve plate 7. The fan 25 blows air in the direction of movement of the sieve plate to remove fine dust in time and avoid cross contamination.

The positive and negative electric field lines formed between the titanium alloy positive plate 22 and the aluminum negative plate 23 are densely distributed in the raised area, enhancing the force on the charged particles. The high resistance and weak conductivity of the germ powder are deflected in the strong electric field area. More significantly, the titanium alloy positive plate 22 acts as a corona electrode, polarizing the surrounding air molecules through ionization. The germ powder particles preferentially obtain negative charges in the ionization field due to the oil content. Under the action of the electric field force, the negatively charged germ powder particles will be deflected and adsorbed toward the titanium alloy positive plate 22. The aluminum negative plate 23 acts as a dust collecting electrode, and the residual negative charge on the surface forms an electrostatic adsorption field. The positively charged rice bran powder particles will migrate toward the aluminum negative plate 23, thereby automatically separating the germ powder and rice bran powder particles.

[0038] The arched sieve plate 20 is linearly reciprocated left and right, so that the germ powder and the rice bran powder granules are moved in different directions respectively, and the germ powder and the rice bran powder granules enter the arched surface 2001 and fall onto the sieve plate 1 2003 and the sieve plate 2 2004 respectively.

The sieve plate 1 2003 and the sieve plate 2 2004 are 80 mesh sieves and 100 mesh sieves respectively, so that the germ powder flows from the sieve plate 1 2003 to the discharge trough 1 26, so that the rice bran powder granules flow from the sieve plate 2 2004 to the discharge trough 2 27, and the arched sieve plate 20 drives the sieve plate 1 2003 and the sieve plate 2 2004 to move back and forth linearly, thereby facilitating the discharge of the germ powder and the rice bran powder granules. The germ powder and the rice bran powder granules are discharged on the arched sieve plate 2 0 surface is subjected to the combined action of electrostatic field force and mechanical vibration, forming differentiated motion trajectories, thereby separating germ powder and rice bran powder granules for material extraction. Adjustable height baffles 2002 are installed on both sides of the sieve plate to effectively prevent lateral splashing of particles and ensure the cleanliness of the separation process. The arched sieve plate 20 drives sieve plate 1 2003 and sieve plate 2 2004 to vibrate synchronously through reciprocating linear motion. The periodic vibration destroys the adsorption balance between particles and the sieve, reducing the risk of germ powder adhering to sieve plate 1 2003, thereby accelerating the rice bran powder granules to pass through the 100-mesh sieve on sieve plate 2 2004, causing the germ powder to fall into the discharge chute 1 26 along a parabolic trajectory, while the rice bran powder granules vertically pass through the sieve to the discharge chute 2 27, forming automatic separation, thereby further facilitating the extraction of rice bran dietary fiber nutrients.
