Description

Method for obtaining whole embryo by cutting two tips of rice or brown rice at different times and the resulting rice Technical Field

[0001] The invention relates to the technical field of rice processing with retained embryos, and in particular to a method for obtaining whole embryos by cutting two tips of rice or brown rice at different times, and the resulting rice. Background Art

[0002] When existing rice is processed into polished rice, its husk and endosperm are generally ground off. When the endosperm is ground off, the embryo at one end is also ground off. The nutritional value of the embryo is very high, especially many trace elements needed by the human body are stored in the embryo, which makes the nutritional value of the processed polished rice much lower than that of rice. Over the past hundred years, people have discovered the existence of this problem and started to develop equipment for processing embryo-retained rice. During the processing, the rice is ground horizontally or vertically, and a small part of the embryo is retained by controlling the number of grindings. In order to have a better taste, a large part of the endosperm on the surface of the rice is also removed to form embryo-retained rice. The embryo-retained rice obtained by this processing method cannot retain the embryo completely. Once the embryo is lost, the nutrients inside the embryo are lost in large quantities. This kind of embryo-retained rice requires a long time to be steamed, has a bad taste, and cannot retain all the nutrients.

[0003] A Chinese patent (publication number: CN110975971B, application date: 2019-12-24) discloses a reciprocating rice or brown rice end cutting device. When the invention cuts the two tips of brown rice at the same time, two blades are fixedly mounted on both sides of the same knife shaft. When the device is in use, since the lengths of the brown rice in the same batch are different, and the spacing between the two knives in the device is fixed, the lengths of the tip segments cut off from the brown rice of different lengths are also different, and it is impossible to ensure that the intact embryo can be retained on the cut tip segment;

[0004] If the length of the brown rice is screened and distinguished before the device is used, no matter whether the length or weight of the brown rice is used to distinguish the brown rice, the different lengths of the brown rice cannot be accurately and detailedly distinguished according to the grade;

[0005] In summary, the existing method of cutting the two tip segments of brown rice simultaneously cannot ensure that the embryo is retained intact on the cut tip segment due to the inconsistency of the length of the brown rice, resulting in a low embryo retention rate.

[0006] Summary of the Invention

[0007] The present invention aims to solve the problem that the lengths of the two tip sections produced by simultaneously cutting both ends of brown rice are inconsistent, and it is impossible to ensure that the cut tip sections retain a complete embryo, thereby resulting in a low embryo retention rate. A method for obtaining a complete embryo by cutting the two tips of rice or brown rice at different times is provided, and the rice produced is also provided.

[0008] The present invention provides a method for obtaining a whole embryo by time-sharing cutting of two tips of rice or brown rice. The time-sharing cutting comprises cutting one tip segment of the brown rice in a first time period and then cutting the other tip segment of the same grain of brown rice in a second time period. The specific steps are as follows:

[0009] 1. The first period:

[0010] ① Step 1: The rice dropping plate 1 moves forward to the first working position under the rice dropping bin 7, and the brown rice is placed into the rice trough 10 on the rice dropping plate 1 through the rice dropping bin 7;

[0011] ② Step 2: The rice dropping plate 1 continues to move forward to the second working position, and the air flow of the No. 1 air power unit 2 on the left or right side of the rice dropping plate 1 passes through the vent 11 connected to the inside of the rice trough 10, so that the brown rice inside the rice trough 10 on the rice dropping plate 1 is aligned toward the other side of the rice trough 10;

[0012] ③ Step 3, the rice falling plate 1 continues to move forward to the third working position, and the aligned end of the brown rice inside the rice trough 10 on the rice falling plate 1 is cut by the first cutting unit 8, completing the cutting of the first tip section of the brown rice to equal length;

[0013] ④ Step 4, the rice dropping plate 1 continues to move forward to the fourth working position. When the first tip section rice hole on the supporting plate 4 corresponds to the rice groove 10 on the rice dropping plate 1, the cut first tip section is discharged and collected through the first tip section rice hole on the supporting plate 4;

[0014] 2. Second time period:

[0015] ① Step 5: The rice dropping plate 1 continues to move forward to the fifth working position, and the second air power unit 6 arranged on the other left or right side of the rice dropping plate 1 is used to blow air in the reverse direction to the brown rice inside the rice trough 10 on the rice dropping plate 1 through the vent 11 on the side, so that the remaining brown rice in the rice trough 10 is aligned toward the other side end of the rice trough 10;

[0016] ② Step 6: The rice falling plate 1 continues to move forward to the sixth working position, and the second cutting unit 9 cuts the other aligned end of the brown rice inside the rice trough 10 on the rice falling plate 1 into equal lengths;

[0017] 3. step seven, rice falling plate 1 continues to move forward to the seventh working position, and when the second tip section rice hole on the supporting plate 4 corresponds to the rice groove 10 on the rice falling plate 1, the second tip section cut off is discharged and collected by the second tip section rice hole on the supporting plate 4, and then completes the complete acquisition of the embryo tip section embryo to the brown rice;

[0018] Furthermore, in the step 1, the brown rice in the rice bin 7 is dropped into the rice trough 10 on the rice falling plate 1 by the relative forward movement of the rice falling plate 1 and the rice falling bin 7. The rice trough 10 is provided on the surface of the rice falling plate 1 and is parallel to each other. The rice trough 10 is connected from top to bottom and is shaped as a long trough that can accommodate brown rice grains. The rice falling bin 7 is "cofferdam-shaped" and is buckled on the surface of the rice falling plate 1. The lower surface of the rice falling plate 1 is a supporting plate, and the rice falling plate 1 is moved forward between the stationary rice falling bin 7 and the stationary supporting plate 4 to realize that the brown rice grains in the rice bin 7 are placed in the rice trough 10 and are carried to the first working position along with the rice falling plate 1.

[0019] Furthermore, the No. 1 air power unit 2 in step 2 and the No. 2 air power unit 6 in step 5 both work in a gas blowing mode;

[0020] Furthermore, the air power unit includes an air chamber and an air compression device, the output end of the air compression device is connected to the inlet end of the air chamber, the outlet end of the air chamber is aligned with the vent 11, and the air chamber is slidably connected to the rice falling plate 1;

[0021] Furthermore, the air power unit further comprises an air pressure container, the output end of the air compression device is connected to the inlet end of the air pressure container, and the outlet end of the air pressure container is connected to the inlet end of the air chamber;

[0022] Furthermore, the cutting position in the steps 3 and 6 is located at 25% to 30% of the distance from the two end points of the rice trough 10 in the length direction, and the cutting is performed by a cutter 3; on the route of the forward movement of the rice falling plate 1, the cutter 3 is a high-speed rotating circular blade, and the upper surface of the rice falling plate 1 is provided with a knife groove for accommodating the tip of the circular blade along the direction of movement. The tangent point between the circular blade and the upper surface of the rice falling plate 1 is located below the upper surface of the rice falling plate 1 and in the knife groove between the upper surfaces of the bottom of the knife groove. When the brown rice grains carried on the rice falling plate 1 pass through the circular blade, they are scratched by the tip of the circular blade, thereby achieving separation between the brown rice tip section and the rice middle section;

[0023] Furthermore, the method for obtaining a whole embryo by cutting the two tips of rice or brown rice in a time-sharing manner further includes step eight, in which the rice dropping plate 1 continues to move forward to the eighth working position, and when the middle section hole on the supporting plate 4 corresponds to the rice trough 10 on the rice dropping plate 1, the cut middle section is lowered to empty the rice trough 10, and then the rice dropping plate 1 returns along the path from step seven to step one, so as to repeat steps one to step seven;

[0024] Furthermore, during the process from step 1 to step 8, the rice-falling plate 1 moves forward until the outlet end of the air chamber in the aerodynamic unit is connected to the vent 11 on the rice-falling plate 1, and air power is output thereto; when the outlet end of the air chamber in the aerodynamic unit fails to be connected to the vent 11 on the rice-falling plate 1, the side of the rice-falling plate 1 is used to seal the gas outflow of the air pressure container, and when the outlet end of the air pressure container is connected to the vent 11 again, the gas pressure is ensured to be sufficient;

[0025] Furthermore, the rice produced by the method of obtaining a whole embryo by cutting the two tips of rice or brown rice at different times is made of a mixture of oblate cones of rice of equal volume, each accounting for 50%, and 50% of the oblate cones of rice contain complete embryos.

[0026] Furthermore, the rice produced by the method of obtaining a whole embryo by cutting the two tips of rice or brown rice at different times is composed of oblate conical rice and oblate cylindrical rice, wherein the amount of oblate cylindrical rice is half the amount of oblate conical rice; wherein the oblate conical rice is a mixture of oblate conical rice of equal volume, each accounting for 50%, and 50% of the oblate conical rice contain a complete embryo.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention solves the major problem of "rice with intact embryo and good taste" that humans have been trying to solve for a hundred years but have failed to solve, so that people can eat healthy rice. The present invention uses an air power unit to align the brown rice in the rice trough on the rice drop plate twice towards different ends, and after the brown rice ends are aligned each time, a cutting device is used to cut the tip of the rice grain. Therefore, this cutting method cuts the two tips of the rice grain in different time periods and times, and each grain of rice will undergo two cutting processes, thereby avoiding the problem that the existing brown rice processing machine uses a pair of blades with a fixed spacing to cut brown rice of different lengths, resulting in two cut tip sections of unequal lengths, so that the embryo on the tip section with embryo cannot be completely extracted.

[0029] In addition, the vent hole and the connection point between the air vent and the inner end surface of the rice trough on the rice falling plate are used to limit the brown rice. The above structure is used to realize axial limitation of the brown rice. According to actual measurement of the length of embryos of different brown rice, the length of the complete embryo from the tip of the brown rice occupies 25% to 27% of the length of the brown rice, thereby allowing the existence of inconsistent lengths of the brown rice within a certain range during the rice cutting process. Therefore, the cutting position is selected at 25% to 30% of the length direction of the rice trough, thereby ensuring that the lengths of the two tip sections cut from the brown rice of different lengths are equal, and simultaneously ensuring that a complete embryo is retained on one of the tip sections cut from a grain of brown rice, greatly improving the embryo retention rate, which can be increased to more than 95%. For rice of the same model and variety planted at the same time, the length difference is approximately 2 mm. In this case, complete embryos can be obtained using the method of the present invention.

[0035] Specific embodiment 1: This embodiment is described with reference to Figures 1 to 5. The method of obtaining a whole embryo by time-sharing cutting of two tips of rice or brown rice is described in this embodiment. The time-sharing cutting is to cut a tip segment of brown rice in a first time period, and then cut the other tip segment of the same brown rice in a second time period. The specific steps are as follows:

[0036] 1. The first period:

[0037] ① Step 1: The rice dropping plate 1 moves forward to the first working position under the rice dropping bin 7, and the brown rice is placed into the rice trough 10 on the rice dropping plate 1 through the rice dropping bin 7;

[0038] ② Step 2: The rice dropping plate 1 continues to move forward to the second working position, and the air flow of the No. 1 air power unit 2 on the left or right side of the rice dropping plate 1 passes through the vent 11 connected to the inside of the rice trough 10, so that the brown rice inside the rice trough 10 on the rice dropping plate 1 is aligned toward the other side of the rice trough 10;

[0039] ③ Step 3, the rice falling plate 1 continues to move forward to the third working position, and the aligned end of the brown rice inside the rice trough 10 on the rice falling plate 1 is cut by the first cutting unit 8, completing the cutting of the first tip section of the brown rice to equal length;

[0040] ④ Step 4, the rice dropping plate 1 continues to move forward to the fourth working position. When the first tip section rice hole on the supporting plate 4 corresponds to the rice groove 10 on the rice dropping plate 1, the cut first tip section is discharged and collected through the first tip section rice hole on the supporting plate 4;

[0041] 2. Second time period:

[0042] ① Step 5: The rice dropping plate 1 continues to move forward to the fifth working position, and the second air power unit 6 arranged on the other left or right side of the rice dropping plate 1 is used to blow air in the reverse direction to the brown rice inside the rice trough 10 on the rice dropping plate 1 through the vent 11 on the side, so that the remaining brown rice in the rice trough 10 is aligned toward the other side end of the rice trough 10;

[0043] ② Step 6: The rice falling plate 1 continues to move forward to the sixth working position, and the second cutting unit 9 cuts the other aligned end of the brown rice inside the rice trough 10 on the rice falling plate 1 into equal lengths;

[0044] 3. step seven, rice falling plate 1 continues to move forward to the seventh working position, and when the second tip section rice hole on the supporting plate 4 corresponds to the rice groove 10 on the rice falling plate 1, the second tip section cut off is discharged and collected by the second tip section rice hole on the supporting plate 4, and then completes the complete acquisition of the embryo tip section embryo to the brown rice;

[0045] In the present specific embodiment, an aerodynamic unit is adopted to align the brown rice inside the rice trough on the rice falling plate 1 by one end twice, and then the brown rice is limited by the connection between the air vent 11 and the inner end face of the rice trough on the rice falling plate 1. When the aerodynamic unit blows air to the brown rice end through the air vent 11, the brown rice now has a tendency to slide toward one end in the rice trough until the brown rice is penetrated into the air vent 11. The axial direction of the brown rice is limited, thereby effectively solving the problem of inconsistent brown rice lengths during rice cutting, and then ensuring that the lengths of the two tip sections cut off from brown rice of different lengths are the same, and also ensuring that a complete embryo is retained on one of the tip sections cut off from a grain of brown rice, thereby greatly improving the embryo retention rate.

[0046] After the first or second air blowing, the tips of the brown rice will penetrate into the air holes on the inner side of the rice trough on the aligned side, thereby achieving the positioning of the brown rice during the cutting process, thereby ensuring the accuracy of the cutting position;

[0047] The tip segment with intact embryo obtained by the time-sharing cutting method is subjected to flexible micro-grinding and then steamed and eaten; or the two tip segments are ground into rice flour and made into rice paste for consumption, the nutritional value of which is many times higher than that of the rice paste containing the middle segment; or the middle segment is subjected to flexible micro-grinding to remove the seed coat on the outer surface of the middle segment, thereby retaining the aleurone layer and endosperm, and then mixed with the tip segment for steaming and eating, thereby achieving the purpose of retaining the embryo intact and having a good taste;

[0048] The above three ways of eating can allow the nutrients inside the germ of brown rice to be fully absorbed by the human body through eating. Compared with eating the existing germ-retained rice produced by grinding, it has more nutrition and tastes better.

[0049] Specific embodiment 2: The present embodiment is described in conjunction with Figures 1 to 5. This embodiment is a further limitation of the rice cutting method described in specific embodiment 1. The present embodiment describes a method for obtaining a whole embryo by cutting the two tips of rice or brown rice in a time-sharing manner. In the step 1, the brown rice in the rice bin 7 is dropped into the rice trough 10 on the rice falling plate 1 by the relative forward movement of the rice falling plate 1 and the rice falling bin 7. The rice trough 10 is provided on the surface of the rice falling plate 1 and is parallel to each other. The rice trough 10 is connected from top to bottom and is shaped like a long trough that can accommodate the brown rice grains. The rice falling bin 7 is "cofferdam-shaped" and is buckled on the surface of the rice falling plate 1. The lower surface of the rice falling plate 1 is a supporting plate. The rice falling plate 1 moves forward between the stationary rice falling bin 7 and the stationary supporting plate 4 to realize that the brown rice grains in the rice bin 7 are placed in the rice trough 10 and are carried to the first working position along with the rice falling plate 1.

[0050] In this specific embodiment, the rice-falling bin 7 is fixed on the frame 5, and the lower surface of the rice-falling bin 7 is in seamless sliding contact with the upper surface of the rice-falling plate 1, and then the driving mechanism is used to pull the rice-falling plate 1 back and forth, thereby achieving the goal of dropping the brown rice in the rice-falling bin 7 into the rice trough of the rice-falling plate 1.

[0051] Specific embodiment three: This embodiment is described in conjunction with Figures 1 to 5. This embodiment further limits the rice cutting method described in specific embodiment one. This embodiment describes a method for obtaining a whole embryo by cutting the two tips of rice or brown rice in time. The air power unit No. 1 2 in step 2 and the air power unit No. 2 6 in step 5 both work by blowing out gas.

[0052] Specific embodiment 4: This embodiment is described in conjunction with Figures 1 to 5. This embodiment further limits the rice cutting method described in specific embodiment 3. This embodiment describes a method for obtaining a whole embryo by cutting the two tips of rice or brown rice in a time-sharing manner. The air power unit includes an air chamber and an air compressor. The output end of the air compressor is connected to the inlet end of the air chamber, and the outlet end of the air chamber is aligned with the vent 11. The air chamber is slidably connected to the rice falling plate 1.

[0053] This specific embodiment adopts the blow-out gas mode to work, and the air source is air. This medium will not pollute the brown rice and will not pollute the device. In addition, this medium can be reused. When performing step eight, the air is blown out by the air power unit, and the device can also be cleaned without manually cleaning the device.

[0054] Regarding the use of negative pressure suction to absorb and move the brown rice, it is an equivalent replacement feature of the pressure vessel for pushing the brown rice. However, the structure for achieving the negative pressure suction to absorb and move the brown rice is more complicated than that of the pressure air blowing device, so its cost is also high and the accuracy is difficult to control.

[0055] Specific embodiment five: This embodiment is described in conjunction with Figures 1 to 5. This embodiment further limits the rice cutting method described in specific embodiment four. This embodiment describes a method for obtaining a whole embryo by cutting the two tips of rice or brown rice in time. The air power unit also includes an air pressure container, the output end of the air compression device is connected to the inlet end of the air pressure container, the outlet end of the air pressure container is connected to the inlet end of the air chamber, and the outlet end of the air chamber is aligned with the vent 11.

[0056] Specific embodiment six: This embodiment is described in conjunction with Figures 1 to 5. This embodiment is a further limitation of the rice cutting method described in specific embodiment one. The method described in this embodiment is a time-sharing method for cutting the two tips of rice or brown rice to obtain a whole embryo. The cutting position in the steps three and six is ​​located at 25% to 30% of the distance from the two end points of the rice trough 10 in the length direction, and the cutting is performed by a cutter 3; on the route of the forward movement of the rice falling plate 1, the cutter 3 is a high-speed rotating circular blade, and the upper surface of the rice falling plate 1 is provided with a knife groove for accommodating the tip of the circular blade along the direction of movement. The tangent point between the circular blade and the upper surface of the rice falling plate 1 is located below the upper surface of the rice falling plate 1 and in the knife groove between the upper surface of the bottom of the knife groove. When the brown rice grains carried on the rice falling plate 1 pass through the circular blade, they are scratched by the knife tip of the circular blade, thereby achieving separation between the tip section of the brown rice and the middle section of the rice;

[0057] In this specific embodiment, the cutting position is located at 25% to 30% from the two end points in the length direction of the rice trough. According to actual measurements of the embryo lengths of different brown rice, the length of the embryo occupies 25% to 27% of the brown rice, thereby ensuring that the lengths of the two tip segments cut from brown rice of different lengths are the same, and also ensuring that a complete embryo is retained on one of the tip segments cut from a grain of brown rice, thereby greatly improving the embryo retention rate.

[0058] Specific embodiment seven: This embodiment is explained in conjunction with Figures 1 to 5. This embodiment is a further limitation of the rice cutting method described in specific embodiment six. The method of obtaining a whole embryo by cutting the two tips of rice or brown rice in time described in this embodiment also includes step eight. Step eight is that the rice dropping plate 1 continues to move forward to the eighth working position. At this time, when the middle section hole on the supporting plate 4 corresponds to the rice trough 10 on the rice dropping plate 1, the cut middle section is lowered to empty the rice trough 10, and then the rice dropping plate 1 returns along the path from step seven to step one to achieve repetition of steps one to step seven.

[0059] Specific embodiment eight: This embodiment is illustrated in conjunction with Figures 1 to 5. This embodiment is a further limitation of the rice cutting method described in specific embodiment four or five. This embodiment describes a method for obtaining a whole embryo by cutting the two tips of rice or brown rice in time. During the process from step one to step eight, the rice falling plate 1 moves forward until the outlet end of the air chamber in the aerodynamic unit is connected to the vent 11 on the rice falling plate 1, and aerodynamic force is output thereto; when the outlet end of the air chamber in the aerodynamic unit fails to be connected to the vent 11 on the rice falling plate 1, the side of the rice falling plate 1 realizes sealing of the air outflow of the air chamber, and when the outlet end of the air chamber is connected to the vent 11 again, it ensures that the gas pressure is sufficient.

[0060] Specific embodiment nine: This embodiment is described in conjunction with Figures 1 to 5. The rice produced by the method of obtaining a whole embryo by cutting the two tips of rice or brown rice at different times in this embodiment is a mixture of oblate cones of rice of equal volume, each accounting for 50%, and 50% of the oblate cones of rice contain complete embryos.

[0061] If rice is used directly as the raw material of this method, the rice should be husked to become brown rice before step 1. The rice husking process is an existing technology. Otherwise, some rice husks will remain on the two tip ends after cutting, which will be difficult to cook and have a bad taste. The middle section will also be difficult to remove the shell and pericarp layer by flexible grinding, leaving only the endosperm and endosperm.
