Description

Technical Field

[0001] The invention relates to the technical field of self-heating rice production, in particular to a self-heating rice production line and a self-heating rice production method. Background Art

[0002] Self-heating rice refers to a staple food produced on a large scale by industrial means. It only needs simple cooking before consumption or can be eaten directly. Its flavor, taste and appearance are consistent with ordinary rice. Self-heating rice is easy to eat and carry, and has the aroma of natural rice. It is mainly divided into four types: dehydrated, semi-dry, frozen and canned. With the development of the self-heating rice industry, self-heating rice of various flavors has appeared on the market, such as seafood flavor, barbecue flavor, etc., and the main nutrients contained in self-heating rice of different flavors are also different. For example, seafood-flavored self-heating rice contains a large amount of astaxanthin, which has the effect of whitening and antioxidant. Adding it to self-heating rice can increase the nutritional content of self-heating rice. The production process of seafood-flavored self-heating rice is mainly made by adding shrimp skin to rice. At the same time, shrimp skin has the characteristics of high protein and high calcium, and the production of self-heating rice needs to be carried out through a production line. Therefore, we have launched a self-heating rice production line and a self-heating rice production method.

[0003] The existing patent (Announcement No.: CN108850846B) discloses a self-heating rice production line including a rice washing device, a rice soaking device, a filling device, a microwave cooking device, a film sealing device, and a secondary ripening and sterilization device. The rice washing device conveys the washed rice to the rice soaking device, and the rice soaking device conveys the soaked rice to the filling device. The filling device quantitatively conveys the soaked rice and the nutrient solution to the cooking box; the microwave cooking device heats and cooks the rice and the nutrient solution in the cooking box, and actively discharges steam after the rice in the cooking box is evenly ripened to accelerate the dissipation of the nutrient solution in the cooking box; the film sealing device seals the cooking box containing the ripened rice to obtain a semi-finished cooking box; the secondary ripening and sterilization device performs high-temperature sterilization and secondary ripening. The invention also provides a self-heating rice production method. Through the processes of rice selection, rice soaking, microwave ripening, secondary ripening, etc., the viscosity between the rice grains after cooking is small, chewy, and has a good taste. The rice does not regenerate, which is suitable for making self-heating rice. The existing technology has the following problems: the existing self-heating rice production line uses a filling device to first inject the nutrient solution into the cooking box, and then puts the rice into the cooking box. This method will cause the rice at the bottom to absorb too much nutrient solution and the nutrient solution is unevenly distributed. At the same time, the moisture content of the rice that has absorbed the nutrient solution is also different, and the taste of the steamed rice will be different. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 technical personnel in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 9 The present invention provides a technical solution: a self-heating rice production line, comprising a base 1, the top surface of the base 1 is respectively fixedly connected with a washing component 2 and a forming component 6, one side of the washing component 2 is connected with a rice pump 3, the rice pump 3 is connected to a rice steaming mechanism 5 through a rice pipe 4, a conveyor belt 7 is provided on one side of the base 1, and a packaging mechanism 8 and a detection mechanism 9 are respectively provided in the middle of the conveyor belt 7.

[0022] In this embodiment, Figures 2 to 5As shown, the forming assembly 6 includes a conveying motor 601 fixedly connected to the top surface of the base 1, the output end of the conveying motor 601 is fixedly connected to an auger 602, the auger 602 is arranged at the inner middle part of the conveying cylinder 603, the upper part of the conveying cylinder 603 is connected with a lower hopper 604, the end of the auger 602 close to the conveying motor 601 is fixedly connected to a driving cylinder 605, the end of the driving cylinder 605 away from the conveying motor 601 is provided with an annular limiting groove 606, the inner part of the annular limiting groove 606 is slidably connected with a driving rod 607, the driving rod 607 is divided into a hollow rod 607a and a solid rod 607b, the end of the driving rod 607 away from the driving cylinder 605 is abutted with a butt joint The plate 608 is fixedly connected to one end of the driven rod 609, and the other end of the driven rod 609 is fixedly connected to a blocking plate 6010, and the blocking plate 6010 is slidably connected to the inside of the liquid inlet 6011, and the liquid inlet 6011 is arranged in the middle of the cylinder wall of the delivery cylinder 603, and a liquid inlet ring 6012 is integrally formed on the outer side of the delivery cylinder 603 in the area where the liquid inlet 6011 is located, and the liquid inlet ring 6012 is connected to the infusion pump 6013, and the liquid inlet end of the infusion pump 6013 is connected to the liquid storage tank 6014, and the bottom surface of the liquid storage tank 6014 is connected to the top surface of the base 1, and a return spring 6015 is provided between the liquid inlet ring 6012 and the abutting plate 608;When the rice is cooked, the worker opens the bottom of the rice steaming mechanism 5 to allow the cooked rice to fall into the lower hopper 604, and then starts the conveying motor 601 in the forming assembly 6. The conveying motor 601 drives the auger 602 to rotate and convey the rice in the lower hopper 604 to the end of the conveying cylinder 603. During this process, the auger 602 also drives the driving cylinder 605 to rotate. Since the end of the driving cylinder 605 that contacts the driving rod 607 is an inclined structure, the driving cylinder 605 can drive the hollow rod 607a and the solid rod 607b at the end to move when rotating. The driving cylinder 605 The hollow rod 607a and the solid rod 607b are pushed toward the end of the conveying cylinder 603 in sequence, and the abutment piece 608 is pushed to the right by the hollow rod 607a and the solid rod 607b. The abutment piece 608 will drive the driven rod 609 to move synchronously. When the driven rod 609 moves, it will push the blocking plate 6010 to move to the right, and the blocking of the blocking plate 6010 on the liquid inlet 6011 is released. At this time, the nutrient solution in the liquid inlet ring 6012 will enter the conveying cylinder 603 and mix with the rice. It should be noted that since the auger 602 and the driving cylinder 605 rotate coaxially, the auger 60 2 and the driving cylinder 605 are relatively stationary. When the driving cylinder 605 rotates one circle, the liquid inlet 6011 will be opened one by one. At the same time, the auger 602 will just transport the rice within one pitch from the coverage area of ​​the liquid inlet 6011. This structure can make the rice in each pitch of the auger 602 be injected with nutrient solution at 360°, so that the nutrient solution is evenly distributed, and there will be no situation where the finished rice tastes different due to excessive nutrient solution in some parts. When the lower side of the end of the driving cylinder 605 contacts the driving rod 607, the driving rod 607 at this time will be driven to the conveying motor. 601 is pulled on the side where the driving rod 607 contacts the abutment sheet 608, the reset spring 6015 rebounds and drives the driven rod 609 to reset in the direction where the conveying motor 601 is located, and the driven rod 609 drives the blocking plate 6010 to block the liquid inlet 6011 again, blocking the nutrient solution in the liquid inlet ring 6012 from entering the inside of the conveying cylinder 603. The width of the opening part of the annular limiting groove 606 is smaller than the width of its interior, and the end of the driving rod 607 inserted in the annular limiting groove 606 is spherical, so the driving rod 607 will not be separated from the driving cylinder 605. ;

[0023] In this embodiment, Figure 4 and Figure 6As shown, the hollow rod 607a passes through the middle of the lower hopper 604, and the outer surface of the hollow rod 607a is integrally formed with two limit bars 6016, and the two limit bars 6016 are slidably connected to the inside of the bar-shaped limit groove 6017, and the bar-shaped limit groove 6017 is provided on the inner wall surface of the rotating sleeve rod 6018, and the outer surface of the rotating sleeve rod 6018 is integrally formed with a plurality of crushing rods 6019, and the solid rod 607b is slidably passed through the middle of the crescent plate 6032, and the crescent plate 6032 is connected to the outer surface of the conveying cylinder 603; when the hollow rod 607a rotates, it can pass through the limit bars 6016 to crush the solid rod 607b. 016 and the bar-shaped limit groove 6017 cooperate to drive the rotating sleeve 6018 to rotate, and the rotating sleeve 6018 drives the crushing rod 6019 to rotate synchronously to crush the rice dropped in the lower hopper 604 to prevent the rice from clumping and causing the discharge part of the lower hopper 604 to be blocked. In addition, the rotating sleeve 6018 is located inside the lower hopper 604, and the rotating sleeve 6018 and the hollow rod 607a are slidably connected. Therefore, when the hollow rod 607a is driven by the driving cylinder 605, the rotating sleeve 6018 will not make a linear reciprocating motion with the hollow rod 607a, and always remain inside the lower hopper 604.

[0024] In this embodiment, Figure 7 As shown, a spiral groove 6020 is provided on the inner wall surface of the hollow rod 607a, and a driving protrusion 6021 is slidably connected inside the spiral groove 6020. The driving protrusion 6021 is integrally formed on the outer surface of the fixed rod 6022, and the fixed rod 6022 is fixedly connected to one side of the abutment sheet 608; when the hollow rod 607a reciprocates along its own axis, the spiral groove 6020 on its inner wall cooperates with the driving protrusion 6021. Since the driving protrusion 6021 is fixedly connected to the fixed rod 6022, and the fixed rod 6022 is connected through the abutment sheet 608, the driven rod 609 and the blocking plate 6010, the blocking plate 6010 cannot rotate in the liquid inlet 6011. Therefore, the hollow rod 607a will reciprocate in the cooperation of the spiral groove 6020 and the driving protrusion 6021, thereby driving the rotating sleeve rod 6018 to rotate, and finally driving the crushing rod 6019 to rotate.

[0025] In this embodiment, Figure 4As shown, a housing 6023 is fixedly sleeved on the outer ring of one end of the conveying cylinder 603 away from the conveying motor 601, a discharge pipe 6024 is integrally formed below the housing 6023, and a refrigerator 6025 is connected to the side of the housing 6023 away from the conveying cylinder 603; the refrigerator 6025 injects refrigerated air into the housing 6023, and the air enters between the cutting shell 6034 and the extrusion plate 6026 through a plurality of air holes in the middle of the cutting shell 6034, so as to quickly cool the extruded self-heating rice. Because the main component of rice is starch, the recovery of rice is actually the aging of starch. However, when the starch is below 18°C, aging will not occur. Therefore, the refrigerator 6025 mainly cools the rice to prevent the rice from being recycled. At the same time, it can also reduce the temperature of the newly formed rice, so that the moisture on the surface of the rice condenses to prevent the rice grains from sticking together.

[0026] In this embodiment, Figure 8 and Fig. 9 As shown, an extrusion plate 6026 is integrally formed between the inner walls of the shell 6023, and the extrusion plate 6026 is fitted with the end of the conveying cylinder 603. A plurality of groups of extrusion holes 6027 and arc-shaped slide grooves 6028 are respectively provided on the side of the extrusion plate 6026 away from the conveying cylinder 603. A slider 6029 is slidably connected inside the arc-shaped slide groove 6028, and an arc spring 6030 is fixedly connected between one side of the slider 6029 and the inner wall of the arc-shaped slide groove 6028. The slider 6029 extends to the outside of the arc-shaped slide groove 6028 and is connected to the guide plate 6031. One end of the auger 602 away from the conveying motor 601 passes through the middle of the extrusion plate 6026 and is connected to the cylindrical ring 6033. The cylindrical ring 6033 is integrally formed in the middle of the inner side of the cutting shell 6034, and a lever 6035 is fixedly connected to the outer surface of the cylindrical ring 6033. The inner wall of the cutting shell 6034 is equiangularly distributed with a plurality of cutting plates 6036, and a movable limiting plate 6037 is hinged on one side of the cutting plate 6036 close to the cylindrical ring 6033, and a plurality of impact rods 6038 are integrally formed on one side of the cutting plate 6036. The cutting shell 6034 is divided into a plurality of chambers by the cutting plates 6036, and a discharge port 6039 is provided on the inner wall of one of the chambers, and a temporary storage chamber is formed between every two cutting plates 6036; when the rice is extruded from the extrusion hole 6027, the auger 602 drives the cylindrical ring 6033 to rotate synchronously, and the cylindrical ring 6033 drives the cutting shell 6034 to rotate, and the cutting shell 6034 drives the cutting plate 6036 to rotate, so as to cut the extruded self-heating rice, and the cut self-heating rice will slide along the smooth side of the cutting plate 6036 and impact on the outer surface of the cylindrical ring 6033, refer to Figure 8The cutting plate 6036 rotates clockwise, and the cut self-heating rice will fall vertically to the side of the cutting plate 6036 with the impact rod 6038 after hitting the cylindrical ring 6033. The collision of the impact rod 6038 separates the rice grains stuck together, and the self-heating rice is driven by the cutting plate 6036 to the left side of the cylindrical ring 6033. When the self-heating rice rises to the moving height, it will slide from the higher cutting plate 6036 to the lower cutting plate 603 6, and due to the obstruction of the guide plate 6031, the self-heating rice does not enter the temporary storage chamber located directly below the cylindrical ring 6033 until the cylindrical ring 6033 rotates one circle. At this time, the self-heating rice between the cutting shell 6034 and the extrusion plate 6026 accumulates more and more, and the lever 6035 on the outer ring of the cylindrical ring 6033 contacts the guide plate 6031 and pushes the guide plate 6031 in the clockwise direction, and the guide plate 6031 drives the slider 6029 to move and squeeze the arc The spring 6030 and the guide plate 6031 block the temporary storage cavity at the lower left of the cylindrical ring 6033 and release the blocking of the temporary storage cavity directly below the cylindrical ring 6033. Therefore, the self-heating rice falling from the temporary storage cavity at a high position will slide along the guide plate 6031 into the temporary storage cavity directly below the cylindrical ring 6033. In addition, a discharge port 6039 is provided on the wall of the cutting shell 6034 where the temporary storage cavity is located. The self-heating rice is discharged from the discharge port 6039 into the discharge pipe 6024. Finally, the rice falls into the self-heating rice box on the conveyor belt 7. The cycle of each discharge of the self-heating rice is one rotation of the conveying motor 601. Therefore, the weight and cycle of the self-heating rice discharged each time are fixed, which can better cooperate with the self-heating rice box on the conveyor belt 7, so that the self-heating rice that falls each time can fall into the self-heating rice box. The self-heating rice box is conveyed by the conveyor belt 7 to the packaging mechanism 8 for sealing and packaging. Finally, the conveyor belt 7 sends the packaged self-heating rice to the detection mechanism 9 for detection.

[0027] In this embodiment, Figure 1 and Figure 3 As shown, the washing component 2 includes a washing cylinder 201 fixedly connected to the top surface of the base 1, a washing motor 202 is fixedly connected to the top of the washing cylinder 201, the output end of the washing motor 202 extends to the inside of the washing cylinder 201 and is connected to the stirring blade 203, an ultraviolet lamp 204 is fixedly installed on the inner wall of the washing cylinder 201, a rice inlet and a drain outlet are respectively provided on one side of the washing cylinder 201, and an interception net is provided on the inner wall of the pipe mouth of the drain outlet; the washing motor 202 drives the stirring blade 203 to wash the rice grains in the washing cylinder 201, and the ultraviolet lamp 204 can sterilize the rice grains.

[0028] The self-heating rice production method uses the self-heating rice production line as described above, and comprises the following steps: Step S001, adding the selected rice into the washing cylinder 201 and adding a proper amount of clean water, using the washing motor 202 to drive the stirring blade 203 to stir and wash the rice; Step S002, draining the water in the washing cylinder 201 through the drain port of the washing cylinder 201, adding water to the washing cylinder 201 again, soaking the rice for 30 minutes, and increasing the moisture content of the rice; Step S003, after the soaking is completed, the water in the washing cylinder 201 is drained, and then the rice pump 3 is started to suck the rice in the washing cylinder 201 into the rice steaming mechanism 5, and the rice is steamed by the rice steaming mechanism 5; Step S004, opening the rice steaming mechanism 5 to discharge the steamed rice into the molding component 6, adding the nutrient solution containing astaxanthin and extruding it into shape; Step S005, the self-heating rice that has been formed falls into a packaging box on the conveyor belt 7, and is transported by the conveyor belt 7 to a packaging mechanism 8 for packaging; Step S006, finally, the packaged self-heating rice is inspected for foreign matter by the inspection mechanism 9 to prevent foreign matter such as metal impurities from being mixed into the finished self-heating rice.

[0029] The use method and advantages of the present invention: When the self-heating rice production line and the self-heating rice production method are used, the working process is as follows: First, the rice is added to the washing mechanism for cleaning, sterilization and soaking, and then the rice pump 3 injects the rice grains into the rice steaming mechanism 5 for steaming, and then the self-heating rice is formed by the forming component 6, and astaxanthin and other nutrients are added during the forming process, and the addition is 360° all around, which is more uniform and prevents the occurrence of excessive local nutrient solution resulting in different tastes of the rice produced. At the same time, during the forming process, the conveying motor 601 will also drive the crushing rod 6019 to crush the lumpy rice to prevent clogging the discharge hopper 604 and affecting the discharge. Finally, the extrusion part in the forming component 6 extrude, form and break up the self-heating rice, and the weight of the self-heating rice discharged each time is the same, ensuring the production quality.
