Description

Technical Field

[0001] The present invention relates to the technical field of extruders, and particularly to an extruder for making instant cooked rice for brewing. Background Art

[0002] Convenient rice is a processed rice product, also known as artificial rice. It is made from broken rice, rice embryos and other raw materials through processes such as pulverization, water addition and stirring, puffing and forming, cooling, drying, and sieving, and its appearance is like that of rice. When the rice is heated to 100°C, the water in the rice grains begins to boil and the volume expands rapidly until it can no longer expand. When the rice is further heated, the cell membranes in the rice grains are damaged, allowing more water molecules to penetrate into the interior of the rice grains. As the water content increases, the starch inside the rice grains begins to soften and finally forms loose, disordered starch networks. When the rice cools to a certain extent, these loose starch networks will recombine to form a firm, plastic substance, which is the instant brewing rice.

[0003] Dried small shrimps are highly nutritious. The protein content is higher than that of aquatic products such as large yellow croaker, rice field eel, prawn, hairtail, butterfish, etc. and meat products such as beef, pork, and chicken. In addition, the quantity and variety of minerals are rich. Besides containing iodine elements lacking in terrestrial and freshwater organisms, the contents of iron, calcium, and phosphorus are also very rich. Dried small shrimps are known as the "calcium depot". Dried small shrimps also contain astaxanthin, which is the strongest antioxidant discovered so far and is also called super vitamin E. Astaxanthin can play roles such as counteracting free radicals, enhancing immunity, and supplementing nutrition. In order to endow the rice with seafood flavor and functions such as high protein, high calcium, and strong antioxidant properties, dried small shrimp powder, additives and rice flour can be mixed when making instant rice, so that the instant rice has corresponding nutritional value after forming, and it can ensure that the instant rice increases nutrition for consumers after extrusion forming.

[0004] An extruder for making instant brewing convenient rice with the announcement number CN213486769U. In the transportation part of the food processor of this utility model, different gradient temperature regions are set, ensuring that the rice flour is heated during transportation, facilitating the ripening of the rice flour during extrusion, and preventing it from being carbonized due to over-ripening during extrusion. Moreover, the heated powdery material is easy to form during extrusion, improving the ripening efficiency, thus also ensuring the color and density of the extruded finished rice grains, and further ensuring the taste when the convenient rice is brewed. By setting the first region below the feed inlet at room temperature, the temperature of the third region is higher than that of the second region, the temperature of the fifth region is not higher than that of the second region, and the temperatures of the second region and the fourth region are the same. Such a temperature gradient setting enables the powdery material to gradually heat up when being transported forward by the extrusion screw, ensuring that the rice is evenly heated during transportation without local overheating. Supplementary to the heat preservation effect of frictional heat generation during transportation and the frictional heat generation between the extrusion screw and the extrusion die head, it fully ensures that the powdery material is ripened during extrusion without gelatinization and color change. At the same time, extruding the powdery material into shape at a certain temperature also ensures the density of the extruded rice, thus ensuring its shape and taste;

[0005] An extrusion and puffing device for coarse grain convenient rice with the publication number CN105341700A. The extrusion and puffing device for coarse grain convenient rice of this invention has the following advantages: When in use, the user directly introduces the coarse grains into the feed inlet, then connects the extrusion screw to an external motor and starts the heating coil simultaneously. When the temperature in the extrusion cavity reaches the preset puffing temperature, the extrusion screw starts to work, extruding and puffing the coarse grains from the puffing round holes of the puffing orifice plate. Due to the use of an electrically controlled heating coil, the temperature control is precise, avoiding the blockage of the extrusion cavity, having a good puffing effect, high quality of convenient rice, effectively improving the puffing processing efficiency of coarse grain convenient rice, and being highly practical;

[0006] In both of the above two solutions, the ripened rice product is evenly extruded along the pores of the forming die under the extrusion action of the extrusion screw. However, the extrusion pressure generated by the existing extruder is generally fixed, and it is impossible to perform a pressure boosting operation on the shaping of the rice flour extruded from the extrusion die head, making it difficult for conventional rice grains to be more compact after forming. Therefore, we propose an extruder for making instant brewing convenient rice. Summary of the Invention

[0007] The purpose of the present invention is to provide an extruder for making instant brewing convenient rice to solve the problems raised in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solution: An extruder for making instant brewing convenient rice, comprising a machine base, a mounting sleeve and a discharge box. A speed reducer is installed on one side of the machine base, and a support frame is fixed on the other side of the machine base. The speed reducer is installed with an extrusion cavity, and an extrusion screw fixed to the output end of the speed reducer is arranged inside the extrusion cavity. A plurality of heating sleeves are installed on the outer side of the extrusion cavity, and a feeding hopper is installed on one side of the extrusion cavity close to the speed reducer.

A second gear is meshed and connected to the lower side of the first gear. One end of the central shaft of the second gear is fixed with a third gear.

[0013] Preferably, both ends of the central shaft of the second gear are connected through bearings and penetrate through the inner wall of the discharge box. A protective tube welded to the inner wall surface of the discharge box is sleeved on the outer side of the central shaft of the second gear. The third gear is meshed with the rack teeth on the outer wall of the driving sleeve.

[0014] Preferably, a fixed frame is inserted into the lower side outlet of the discharge box. The fixed frame is installed with the discharge box through bolts. A rubber sleeve is bonded to the lower side of the fixed frame, and a sieve hopper is bonded and fixed to the bottom of the rubber sleeve.

[0015] Preferably, a swinging material shaking mechanism is arranged on the outer side of the sieve hopper. The swinging material shaking mechanism includes a driving motor, a limit seat, a driving bevel gear, a driven bevel gear, a first transmission rod and a second transmission rod. Driving motors are installed on both sides of the outer wall of the fixed frame. A driving bevel gear is fixed on the output shaft of the driving motor. Driven bevel gears are meshed and connected on both sides of the driving bevel gear. The first transmission rods are respectively fixed in the middle of the two driven bevel gears. Limit seats are symmetrically welded on the lower side surface of the outer shell of the driving motor. A bearing seat is arranged between the two limit seats. The second transmission rods are respectively connected to both sides of the bearing seat.

[0016] Preferably, transmission gear discs are fixed on the outer sides of the first transmission rod and the second transmission rod. Universal joints are connected to the middles of the first transmission rod and the second transmission rod. Lower turntables and upper turntables are respectively fixed at the ends of the first transmission rod and the second transmission rod far away from the limit seats.

[0017] Preferably, an inclined pull rod is butted on the surface of the lower turntable through an eccentric shaft. A horizontal support rod is movably connected between the two inclined pull rods. The sieve hopper is fixed on the upper side surface of the horizontal support rod. Protrusions are fixed on the outer circumferential sides of the lower turntable and the upper turntable. A discharge port is arranged on one side of the sieve hopper.

[0018] Preferably, an impact block for hitting the outer wall of the sieve hopper is fixed on the outer side of the central axis of the upper turntable on one side of the limit seat. A telescopic sleeve is connected to the outer side of the eccentric shaft of the upper turntable on the other side of the limit seat. A guide rod is connected between the two telescopic sleeves. A buffer spring that abuts against the end of the telescopic sleeve is sleeved on the outer side of the guide rod. A material collecting plate is fixed on the outer side of the telescopic sleeve.

[0019] Preferably, a guide frame is fixed on one side of the limit seat close to the transmission gear disc. Auxiliary limit holes are penetrated through the upper and lower sides of the guide frame. A guide port is arranged on one side of the auxiliary limit hole. A connection box is slidably connected inside the guide port.

[0020] Preferably, auxiliary rollers are connected to the inner sides of the auxiliary limit hole and the connection box. Return springs are symmetrically connected between the connection box and the guide port.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The extruder for making instant brewing convenient rice drives the thin pressing block and the thick pressing block to alternately squeeze the guide wheels on the support rod by the forward rotation of the driving sleeve. By setting two groups of sliding grooves and extrusion columns distributed in a staggered manner, directional sliding is achieved, enabling the two groups of extrusion columns distributed in a staggered equal-angle manner to perform alternating intermittent extrusion operations, which can evenly radially pressurize the formed rice in front of the forming die. At the same time, when using a continuously rotating cutter to cut out rice grains, the driving sleeve can continuously rotate forward to drive the pressurization channel to fully pressurize, and mix shrimp powder, additives, and rice flour to ensure that the rice grains have a plump taste, seafood flavor, and healthy nutritional supplement when eaten;

[0023] 2. The extruder for making instant brewing convenient rice starts a swinging material shaking mechanism outside the sieve hopper. By using two groups of horizontal support rods that move up and down in opposite directions, the two sides of the sieve hopper can be driven to reciprocally lift and swing. Since a discharge port is opened on one side of the sieve hopper, when the two sides of the sieve hopper reciprocally lift and swing, the discharge port on one side of the sieve hopper will have a change in height position. And when the lower turntable and the upper turntable rotate in the same speed in the opposite direction and the protrusions on their outer circumferences collide with each other, the lower turntable and the upper turntable will generate a swinging effect of moving away from each other when rotating, thereby causing the lower turntable to drive the support rods to lift with an accelerated impact, so that the sieve hopper will generate intermittent shaking during regular lifting and swinging, enabling the formed rice grains to undergo an impact test on the forming quality during screening, and the unqualified broken rice grains can be removed along the waste discharge port at the lower side of the sieve hopper;

[0024] 3. The extruder for making instant brewing convenient rice sets two groups of impact blocks to alternately generate positive and negative alternating horizontal impacts on the outside of the sieve hopper, ensuring an alternating knocking effect on the horizontal sides of the outer wall of the sieve hopper to prevent rice grains from adhering to the inner side of the sieve hopper. When the upper turntable near the discharge port of the sieve hopper reciprocally rotates, it will drive the telescopic sleeve to reciprocally stretch and contract, causing the inclined material gathering plates on the two telescopic sleeves to reciprocally move closer to and away from each other, ensuring that the two material gathering plates can scrape the discharge port on one side of the sieve hopper, ensuring that the rice grains are scraped and scattered when being exported from the discharge port to prevent excessive rice grains from sticking together in a group.

Detailed implementation mode

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1-8 , the present invention provides a technical solution: an extruder for making instant brewing convenient rice, including a machine base 1, a mounting sleeve 2 and a discharge box 3. A speed reducer 101 is installed on one side of the machine base 1, a support frame 102 is fixed on the other side of the machine base 1, and leveling feet are connected to both sides of the machine base 1. Place the machine base 1 of the extruder at a designated position, and adjust the leveling feet on both sides of the machine base 1 to achieve the effect of placing and leveling, ensuring the stable placement of the extruder. The speed reducer 101 is installed with the extrusion cavity 103, and an extrusion screw 106 fixed to the output end of the speed reducer 101 is arranged inside the extrusion cavity 103. A plurality of heating sleeves 104 are installed on the outside of the extrusion cavity 103. A feeding hopper 105 is installed on one side of the extrusion cavity 103 close to the speed reducer 101. A pressurization channel 4, a mounting sleeve 2 and a discharge box 3 are successively installed at one end of the extrusion cavity 103 away from the speed reducer 101. A top shaft 201 is inserted into the mounting sleeve 2. One end of the extrusion screw 106 is connected to the inner cavity of the top shaft 201 through a bearing. A forming die 202 is fixed to one end of the top shaft 201. A forming channel is provided on the surface of the forming die 202, which is convenient for the extruder to form and export the rice-like food when extruding rice. A sealing gasket 203 connected to the mounting sleeve 2 is sleeved on the outside of the top shaft 201. By sleeving the sealing gasket 203 on the outside of the top shaft 201, when the pressurization channel 4 is abutted and assembled with the mounting sleeve 2, it can ensure the sealing and protection effect when the rice is extruded and transported to the position of the forming die 202. A motor 301 is installed on the outside of the discharge box 3, and a cutting knife 302 for cutting and forming is installed at the end of the output rod of the motor 301. The output rod of the motor 301 penetrates and inserts into the discharge box 3, and a through hole for the cutting knife 302 to penetrate is provided on one side of the discharge box 3 away from the motor 301;

[0041] A material feeding cavity 406 is provided in the middle of the pressurizing channel 4. Two groups of sliding grooves 401 with equal included angles are provided inside the pressurizing channel 4. An extrusion column 402 is inserted into the inside of the sliding groove 401. A support rod 403 is fixed on one side of the extrusion column 402. A tightening spring 404 is sleeved on the outer side of the support rod 403. One end of the support rod 403 passing through and extending out of the sliding groove 401 is connected with a guide wheel 405. The extrusion column 402 and the sliding groove 401 form an elastic telescopic structure through the tightening spring 404. The two groups of sliding grooves 401 are distributed at equal included angles and are offset inside the pressurizing channel 4. The number of multiple sliding grooves 401 in the same group, the number of thin pressing blocks 501, and the number of thick pressing blocks 502 are all the same;

[0042] The outer side of the extrusion cavity 103 is connected with a driving sleeve 5 through a bearing, and the driving sleeve 5 is arranged on the outer side of the pressurizing channel 4. Thin pressing blocks 501 and thick pressing blocks 502 are fixed at equal included angles on the inner wall of the driving sleeve 5. Rack teeth are arranged at equal included angles on the circumferential side surface of the outer wall of the driving sleeve 5;

[0043] A blower 303 is installed on the top of the discharge box 3. When the rice grains in the discharge box 3 are discharged conveniently, the running blower 303 can blow downward to ensure that the rice grains can be dispersed and discharged. A first gear 304 is fixed on the outer side of the output shaft of the motor 301, and the first gear 304 is arranged on the outer side of the discharge box 3. A second gear 305 is meshed and connected to the lower side of the first gear 304. One end of the central shaft of the second gear 305 is fixed with a third gear 306. The number of teeth of the first gear 304 is less than the number of teeth of the second gear 305. The number of teeth of the third gear 306 is less than the number of teeth of the rack on the outer side of the driving sleeve 5;

[0044] Both ends of the central shaft of the second gear 305 are connected through bearings to penetrate the inner wall of the discharge box 3. A protective tube 307 welded to the inner wall surface of the discharge box 3 is sleeved on the outer side of the central shaft of the second gear 305. The protective tube 307 sleeved on the outer side of the central shaft of the second gear 305 can protect the rotating central shaft to ensure that the rice grains cut and thrown out by the cutter 302 will not be affected. The third gear 306 is meshed with the rack on the outer wall of the driving sleeve 5.

[0045] During specific implementation, when the cooked rice is extruded and conveyed along the extrusion cavity 103, the extrusion screw 106 extrudes and conveys the formed rice to the material feeding cavity 406 in the middle of the pressurizing channel 4. When the motor 301 is started to drive the cutter 302 to rotate, the cutter 302 rotates and cuts the strip-shaped rice exported by the forming die 202. At the same time, the output shaft of the motor 301 drives the first gear 304 to rotate forward. The forward-rotating first gear 304 is meshed and transmitted with the second gear 305 to make the second gear 305 perform a first-stage deceleration and reverse rotation. And because the second gear 305 and the third gear 306 are arranged on the same axis, the third gear 306 can be meshed and transmitted with the rack on the outer side of the driving sleeve 5, so that the reverse-rotating third gear 306 drives the driving sleeve 5 to perform a second-stage deceleration and forward rotation;

[0046] When the driving sleeve 5 rotates forward, it can drive the thin pressing block 501 and the thick pressing block 502 to rotate synchronously. Therefore, the thin pressing block 501 and the thick pressing block 502 alternately squeeze the guide wheel 405 on the support rod 403. Therefore, when the thin pressing block 501 squeezes the guide wheel 405 on the first group of support rods 403, the thin pressing block 501 pushes the support rod 403 and the extrusion column 402 to slide along the chute 401, so that the extrusion columns 402 distributed at equal angles in the same group are simultaneously inserted into the internal part of the material feeding cavity 406 by half. When the thin pressing block 501 disengages from squeezing the guide wheel 405 on the first group of support rods 403, the tightening spring 404 pulls the extrusion column 402 to retract and reset, so that the guide wheel 405 moves in the short-distance reserved groove between the thin pressing block 501 and the thick pressing block 502. The continuously rotating forward driving sleeve 5 will drive the thick pressing block 502 to push the guide wheel 405 on the first group of support rods 403, so that the extrusion columns 402 distributed at equal angles in the first group are simultaneously inserted into the internal part of the material feeding cavity 406 completely. When the thick pressing block 502 disengages from squeezing the guide wheel 405 on the first group of support rods 403, the tightening spring 404 pulls the extrusion column 402 to retract and reset, so that the guide wheel 405 moves in the long-distance reserved groove between the thin pressing block 501 and the thick pressing block 502, and then can alternately drive the extrusion columns 402 distributed in a circular pattern in the first group to perform intermittent extrusion with variable depth, ensuring the pressurized extrusion of the cooked rice conveyed in the material feeding cavity 406;

[0047] When the thick pressing block 502 finishes squeezing and pushing the extrusion columns 402 in the first group, the thin pressing block 501 starts to squeeze and push the second group of support rods 403 distributed at equal angles, so that the extrusion columns 402 distributed at equal angles in the second group are inserted into the internal part of the material feeding cavity 406 by half. After that, the thick pressing block 502 squeezes and pushes the second group of support rods 403 distributed at equal angles again, so that the extrusion columns 402 distributed at equal angles in the second group are inserted into the internal part of the material feeding cavity 406 completely, ensuring that the extrusion columns 402 in the second group can also complete intermittent extrusion with variable depth;

[0048] Therefore, by setting two groups of chutes 401 and extrusion columns 402 distributed in a staggered manner to achieve directional sliding, the extrusion columns 402 distributed at equal angles and in a staggered manner in the two groups can respectively perform alternating intermittent extrusion operations, and then can evenly perform radial pressurization on the formed rice in front of the forming die 202. At the same time, when using the continuously rotating cutting knife 302 to cut out rice grains, the driving sleeve 5 can continuously rotate forward to drive the pressurization channel 4 to be fully pressurized, ensuring that the rice strip exported by the extruder can be more compact, and ensuring that the taste of the rice grains is more plump and chewy when used.

[0049] Please refer to Figures 3-5 、 Figures 9-12, a fixed frame 6 is inserted into the lower side outlet of the discharge box 3. The fixed frame 6 is installed on the discharge box 3 by bolts. A rubber sleeve 7 is bonded to the lower side of the fixed frame 6. A sieve hopper 8 is fixedly bonded to the bottom of the rubber sleeve 7. Waste discharge ports are arranged in an array on the bottom surface of the sieve hopper 8. The fixed frame 6 forms an elastic telescopic structure through the rubber sleeve 7 and the sieve hopper 8.

[0050] During specific implementation, the fixed frame 6 is inserted into the lower side outlet of the discharge box 3, and the bolts on both sides of the fixed frame 6 are rotated so that the bolts are connected in a limited way to both sides of the discharge box 3, thus completing the fastening installation of the fixed frame 6. When the rotating cutter 302 throws out the rice grains, the rice grains will fall into the sieve hopper 8 along the bottom outlet of the discharge box 3 for the screening operation after the rice grains are formed. When the sieve hopper 8 is driven by the swinging material shaking mechanism 9, the elastic assistance of the rubber sleeve 7 can be used to ensure that the movement of the sieve hopper 8 has an active telescopic effect at any angle.

[0051] Please refer to Figure 3 , Figures 9-12 , a swinging material shaking mechanism 9 is arranged on the outside of the sieve hopper 8. The swinging material shaking mechanism 9 includes a driving motor 901, a limit seat 902, a driving bevel gear 903, a driven bevel gear 904, a first transmission rod 905 and a second transmission rod 906. Driving motors 901 are installed on both sides of the outer wall of the fixed frame 6. A driving bevel gear 903 is fixed on the output shaft of the driving motor 901. Driven bevel gears 904 are meshed and connected on both sides of the driving bevel gear 903. First transmission rods 905 are respectively fixed in the middle of the two driven bevel gears 904. Limit seats 902 are symmetrically welded to the lower side surface of the housing of the driving motor 901. A bearing seat is arranged between the two limit seats 902. Second transmission rods 906 are respectively connected to both sides of the bearing seat. A reserved hole is opened in the middle of the bearing seat, and ball bearings are embedded and connected to both sides of the bearing seat. The ball bearings can assist the second transmission rod 906 to rotate easily. The output rod of the driving motor 901 is inserted through the reserved hole in the middle of the bearing seat;

[0052] Driving tooth discs 907 are fixed on the outer sides of the first transmission rod 905 and the second transmission rod 906. Universal joints are connected to the middle parts of the first transmission rod 905 and the second transmission rod 906. Lower turntables 908 and upper turntables 909 are respectively fixed at the ends of the first transmission rod 905 and the second transmission rod 906 far away from the limit seat 902. The universal joints divide the first transmission rod 905 and the second transmission rod 906 into two sections respectively. One section of the first transmission rod 905 and the second transmission rod 906 is set as a fixed transmission part, and the other section of the first transmission rod 905 and the second transmission rod 906 is set as a movable transmission part through the universal joints.

[0053] During specific implementation, the driving motors 901 on both outer sides of the fixed frame 6 are started to drive the driving bevel gear 903 to rotate forward, so that the driving bevel gear 903 drives the two driven bevel gears 904 to engage and rotate in reverse. As a result, the transmission gear discs 907 on the sides of the driven bevel gears 904 follow the reverse rotation. Since transmission gear discs 907 are provided on both the first transmission rod 905 and the second transmission rod 906, and the two transmission gear discs 907 are in meshing transmission, when the first transmission rod 905 follows the reverse rotation of the driven bevel gear 904, it can drive the second transmission rod 906 on the side of the bearing seat to rotate forward. Furthermore, the first transmission rod 905 and the second transmission rod 906 can respectively drive the lower turntable 908 and the upper turntable 909 to rotate in reverse at the same speed.

[0054] Please refer to Figures 9-12 , the surface of the lower turntable 908 is connected to an inclined pull rod 910 through an eccentric shaft. The eccentric shafts of the two lower turntables 908 on the same side of the sieve hopper 8 are distributed in a 180° offset. The two inclined pull rods 910 on both sides of the sieve hopper 8 are symmetrically distributed. A horizontal support rod 911 is movably connected between the two inclined pull rods 910. The sieve hopper 8 is fixed to the upper side of the horizontal support rod 911. Protrusions 912 are fixed on the outer circumferential sides of the lower turntable 908 and the upper turntable 909. The sieve hopper 8 is made of plastic material, and a discharge port is provided on one side of the sieve hopper 8.

[0055] During specific implementation, when the lower turntable 908 and the upper turntable 909 rotate in reverse at the same speed, the two lower turntables 908 on one side of the limit seat 902 will drive the two inclined pull rods 910 on the same side to swing reciprocally through the eccentric shaft, thereby driving the horizontal support rod 911 between the two inclined pull rods 910 to perform reciprocating lifting motion; at the same time, the two lower turntables 908 on the other side of the limit seat 902 will also drive the inclined pull rods 910 to swing reciprocally through the eccentric shaft;

[0056] Since the eccentric shafts of the two lower turntables 908 on the same side of the sieve hopper 8 are distributed in a 180° offset, when the two inclined pull rods 910 on one side drive the horizontal support rod 911 to rise, the two inclined pull rods 910 on the other side will drive the horizontal support rod 911 to move downward. Therefore, by using two groups of horizontal support rods 911 that perform reciprocal lifting motions in opposite directions, the two sides of the sieve hopper 8 can be driven to swing reciprocally up and down. When the two groups of horizontal support rods 911 move away from each other, the bottom of the plastic sieve hopper 8 can be stretched, and when the two groups of horizontal support rods 911 move closer to each other, the bottom of the plastic sieve hopper 8 can be squeezed, so that the bottom surface of the sieve hopper 8 undergoes elastic deformation. As a result, the broken materials in the rice grains are pushed by extrusion at the waste discharge port at the bottom of the sieve hopper 8, thus preventing the waste discharge port from being blocked;

[0057] Since a discharge port is provided on one side of the sieve hopper 8, when the two sides of the sieve hopper 8 perform reciprocating lifting and swinging motions, the height position of the discharge port on one side of the sieve hopper 8 will change and switch. When the lower turntable 908 and the upper turntable 909 rotate in the same speed and reverse directions so that the protrusions 912 on their outer circumferences collide with each other, the lower turntable 908 and the upper turntable 909 will generate a swinging action away from each other during rotation, thereby causing the lifting of the horizontal support rod 911 driven by the lower turntable 908 to generate an accelerated impact, so that the sieve hopper 8 generates intermittent jitters during regular lifting and swinging motions. During screening, the rice grains are subjected to impact tests through jitters in multiple aspects, facilitating the screening out of fragile rice grains, and the non-fragile rice grains are jittered and discharged along the discharge port.

[0058] Please refer to Figures 9-12 , outside the central axis of the upper turntable 909 on one side of the limit seat 902, an impact block 913 for hitting the outer wall of the sieve hopper 8 is fixed. Outside the eccentric shaft of the upper turntable 909 on the other side of the limit seat 902, a telescopic sleeve 914 is connected. Strip-shaped holes are symmetrically provided on both sides of the sieve hopper 8, and the telescopic sleeve 914 is inserted through the strip-shaped holes. A guide rod 915 is connected between the two telescopic sleeves 914. A buffer spring 916 that abuts against the end of the telescopic sleeve 914 is sleeved outside the guide rod 915. The telescopic sleeve 914 forms an elastic telescopic structure through the buffer spring 916 and the guide rod 915. A material collecting plate 917 is fixed outside the telescopic sleeve 914. The material collecting plate 917 is inclined, and the material collecting plate 917 is inserted into the discharge port on one side of the sieve hopper 8.

[0059] During specific implementation, when the upper turntable 909 on one side of the limit seat 902 rotates one circle, the impact block 913 on the central axis of the upper turntable 909 will impact the side surface of the sieve hopper 8, and the impact blocks 913 on both sides of the sieve hopper 8 are arranged in the same direction. Therefore, when the first impact block 913 collides with one side of the sieve hopper 8, the second impact block 913 will rotate to the farthest distance from the sieve hopper 8. At this time, the first impact block 913 will generate a positive horizontal impact on one side of the sieve hopper 8. When the second impact block 913 collides with one side of the sieve hopper 8, the first impact block 913 will rotate to the farthest distance from the sieve hopper 8. At this time, the second impact block 913 will generate a reverse horizontal impact on the other side of the sieve hopper 8, thereby ensuring an alternating knocking effect on the horizontal sides of the outer wall of the sieve hopper 8 and preventing rice grains from adhering to the inner side of the sieve hopper 8;

[0060] When the upper turntable 909 near the discharge port of the sieve hopper 8 reciprocates, the upper turntable 909 near the discharge port drives the telescopic sleeve 914 to reciprocate and stretch in the strip-shaped hole on the side of the sieve hopper 8 through the circumferential rotation of the eccentric shaft. The two telescopic sleeves 914 assist by reciprocatingly pushing and pulling the buffer spring 916 along the guide rod 915, causing the inclined material-gathering plates 917 on the two telescopic sleeves 914 to produce reciprocating motions of approaching and separating from each other, ensuring that the two material-gathering plates 917 can scrape the discharge port on one side of the sieve hopper 8. Furthermore, when the rice grains are exported along the discharge port, the reciprocating scraping of the material-gathering plates 917 can shovel the rice grains in the sieve hopper 8 near the discharge port, ensuring that the rice grains are scattered when exported from the discharge port and preventing excessive rice grains from sticking together in a group.

[0061] Please refer to Figures 9-13 , on one side of the limit seat 902 close to the transmission gear disc 907, a guide frame 10 is fixed. Auxiliary limit holes 11 are penetrated through the upper and lower sides of the guide frame 10. A guide port 12 is arranged on one side of the auxiliary limit hole 11. A connection box 13 is slidably connected inside the guide port 12;

[0062] Auxiliary rollers 14 are connected to the inner sides of both the auxiliary limit hole 11 and the connection box 13. The auxiliary rollers 14 connected to the inner sides of the auxiliary limit hole 11 and the connection box 13 can be used to assist the rotation of the first transmission rod 905 and the second transmission rod 906 respectively, ensuring that the first transmission rod 905 and the second transmission rod 906 have the effect of reducing friction when rotating. A return spring 15 is symmetrically connected between the connection box 13 and the guide port 12.

[0063] During specific implementation, when the protrusion 912 on the outer peripheral side of the lower turntable 908 collides with the protrusion 912 on the outer peripheral side of the upper turntable 909, the lower turntable 908 and the upper turntable 909 will swing away from each other around the universal joint. During the swing, they will respectively drive the movable transmission parts of the first transmission rod 905 and the second transmission rod 906 to deflect and swing. When the movable transmission part swings, it will move along the auxiliary limit hole 11 towards the guide port 12. Thus, the movable transmission part will push the connection box 13 in the guide port 12, causing the connection box 13 to push the return spring 15 to produce elastic buffering. Furthermore, the guide frame 10 can guide the directional swing of the first transmission rod 905 and the second transmission rod 906.

[0064] In summary, when the extruder is in use, the driving device is started to drive the reducer 101 to operate, so that the reducer 101 drives the extrusion screw 106 inside the extrusion cavity 103 to rotate, and the raw materials for making instant rice are injected into the feeding hopper 105. By controlling multiple heating sleeves 104, heating at different temperatures is achieved, so as to carry out the ripening and forming of instant rice. When the instant rice is conveyed to the end of the extrusion cavity 103, the rice is extruded and led out along the forming channels on the surface of the forming die 202. Then, by starting the motor 301 to drive the cutter 302 to rotate, the cutter 302 cuts the strip-shaped rice led out by the forming die 202 into rice grain shapes, thereby producing instant rice for instant brewing. And during the rice preparation process, shrimp powder and additives are mixed with rice flour, so that the formed rice grains have the edible value of astaxanthin, which can not only give the instant rice a seafood flavor, but also ensure a healthy nutritional supplement during sealing. This is the prior art. Specifically, reference can be made to the Chinese patent with the publication number CN1163715A, which discloses nutritional and health-care rice products. In this patent, seafood products are mixed with rice to make various flavored rice nutritional and health-care products. Therefore, when it is necessary to endow instant rice with other flavors and nutritional supplements, the shrimp powder can also be replaced with other edible raw materials. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
