Description

Technical Field

[0001] The invention relates to the technical field of canned lotus root starch production, and in particular to a canned lotus root starch production line and a production method. Background Art

[0002] Lotus root powder is a traditional nourishing food with a long-standing reputation, high nutritional value and good medicinal effect. At present, most of the processing processes of dried lotus root powder are basically fresh lotus root cleaning and peeling, crushing, centrifugal separation of slag water, washing lotus root residue, drying and grinding; in the whole powder making process, crushing, centrifugal separation of slag water, and washing lotus root residue directly affect the output and quality of lotus root powder in the later stage. The steps of direct source of lotus root powder mainly come from the two steps of centrifugal separation of slag water and washing lotus root residue. After the slurry obtained by centrifugal separation of slag water and washing lotus root residue is left to stand and filter for many times, it can be dried and ground; the whole production line has many equipment, complex and cumbersome processes, large power required, and low powder making rate.

[0003] In view of such a situation, the patent with the current publication number CN 107307344A discloses a continuous lotus root powder production line. By combining multiple sets of equipment and adopting an assembly line method, the labor intensity is reduced, time and labor are saved, work efficiency is high, and the rational use of resources is achieved, and production costs are reduced. However, this production line is a conventional processing method for dried lotus root powder. Since the lotus root powder after drying is also ground into powder, the particle size requirements of the lotus root powder particles obtained by centrifugal separation of slag water and washing of lotus root residue are relatively low. If fresh lotus root is directly processed into instant lotus root powder cans using the above-mentioned partial processing of dried lotus root powder, there will be problems that the finished lotus root powder has a rough taste and opaque color. If the dried lotus root powder is rinsed with water and gelatinized into lotus root powder, and then filled, this will inevitably lead to the production cost of filled lotus root powder being much higher than that of dried lotus root powder. If the number of times the slurry obtained by centrifugal separation of the slag water and washing the lotus root slag is allowed to stand and filter is increased, the production cost will undoubtedly increase; at the same time, in the process of constantly standing and filtering the slurry, the particulate matter in the slurry is very easy to settle on the equipment, which not only causes waste but also makes it difficult to handle later. In addition, the more times the lotus root starch slurry is allowed to stand and filter, the more opportunities the anthocyanins and polyphenol oxidase contained in the lotus root starch slurry will come into contact with oxygen in the air. Oxygen will cause the lotus root starch slurry to be oxidized and blackened, and ultimately the finished lotus root starch will be dark and opaque. Summary of the invention

[0044] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] See also Figures 1 to 8 The present application provides a canned lotus root starch production line, including a fresh lotus root starch production system 100, a multi-stage cyclone sorting device 200, a lotus root starch glue-making device 300, a lotus root starch gelatinization device 400, a filling system and a high-temperature disinfection device 800, wherein the fresh lotus root starch production system 100 is used to process fresh lotus roots into lotus root starch slurry; the multi-stage cyclone sorting device 200 is used to perform multi-stage flotation on the lotus root starch slurry output by the fresh lotus root starch production system 100, and the multi-stage cyclone sorting device 200 is provided with a qualified product output end and an unqualified product output end, and the unqualified product output end is connected to the fresh lotus root starch production system 100; the lotus root starch glue-making device 300 is used to perform glue treatment on the lotus root starch slurry discharged from the qualified product output end; the lotus root starch paste The device 400 is used for heating and gelling the gelatinized lotus root powder discharged from the lotus root powder gelling device 300; the filling system comprises a packaging box processing device 500, a filling device 600 and a capping device 700 which are arranged in sequence, the packaging box processing device 500 is used for providing and pre-processing packaging boxes, the filling device 600 can receive the gelatinized lotus root powder discharged from the lotus root powder gelling device 400 and fill the gelatinized lotus root powder into the packaging box discharged from the packaging box processing device 500, the capping device 700 is used for capping and sealing the packaging box output by the filling device 600; the high-temperature sterilizing device 800 is used for high-temperature sterilizing the packaging box sealed by the capping device 700.

[0046] Among them, in the present application, the fresh lotus root powder production system 100 is actually a production equipment for processing fresh lotus roots into lotus root powder slurry, and conventional processing equipment can be used, such as fresh lotus root cleaning and peeling equipment and fresh lotus root crushing and grinding equipment. Of course, the patent CN 107307344 A-a production equipment that removes the drying equipment in a continuous lotus root powder production line can also be used. Of course, in one embodiment of the present application, the fresh lotus root powder production system 100 includes a fresh lotus root peeling equipment and a fresh lotus root crushing and grinding equipment that are connected in sequence, wherein the fresh lotus root peeling equipment can adopt the technical solution in patent CN201510986831.5-red potato peeling device or CN202122622038.0-a drum-type rotary peeling machine, and the fresh lotus root crushing and grinding equipment can adopt the technical solution in CN202320340985.7-a crushing and pulping device or CN201711245573.0-a starch refiner, which is not described in detail in this application. In addition, a slag-water separation device can also be set at the output end of the fresh lotus root crushing and grinding equipment. The slag-water separation device can adopt a traditional rotating centrifugal cylinder structure, or it can adopt the technical solution in CN202310692065.6-A centrifugal filter device for pulp-slag separation and its filtering method, which is not described in detail in this application. It should be noted that the residue separated by the slag-water separation device is processed according to the situation, such as returning to the fresh lotus root crushing and grinding equipment for secondary crushing and grinding, or it can be directly discharged to the outside, and the lotus root powder slurry separated by the slag-water separation device is directly pumped to the multi-stage cyclone sorting device 200 through a pipeline, which can reduce the contact time with the air and avoid it from being oxidized and discolored by oxygen. In addition, the discharge port of the slag-water separation device is also connected to a slurry flushing and dehydration device, which uses the slurry flushing and dehydration equipment to reduce the water content in the lotus root powder slurry, which is beneficial to the processing of the multi-stage cyclone sorting device 200. Generally, only a small amount of pure water is added to the fresh lotus root during the crushing process, so the moisture content in the lotus root powder slurry generally does not exceed the standard. Of course, in some embodiments, the drain port of the slag-water separation equipment can also be directly connected to the multi-stage cyclone sorting device 200, which does not affect the production of the entire product line and only needs to be drained before gluing.

[0047] Among them, the capping device 700 in this application can adopt the technical solutions in CN201720311075.0-a capping machine that can both screw and press caps or CN201510787378.5-a two-in-one capping and pressing manipulator and its capping and pressing methods. In this application, the multi-stage cyclone sorting device 200 needs to work in a relatively closed environment, which can reduce the oxidation of the lotus root powder slurry in contact with the air during the cyclone sorting process. The high-temperature disinfection device 800 in this application is a conventional device. For example, after the packaging boxes are centrally stored, they are sent to a dedicated high-temperature steam disinfection chamber for high-temperature disinfection. They can also be directly sent to the high-temperature steam cabin by a traditional conveyor belt for high-temperature disinfection. In addition, the high-temperature disinfection device 800 in this application can also perform secondary heating on the gelatinized lotus root powder in the packaging box to ensure that the lotus root powder in the packaging box is completely gelatinized.

[0048] The canned lotus root powder production line utilizes a fresh lotus root powder production system 100 to process fresh lotus roots into lotus root powder slurry; and then uses a multi-stage cyclone separation device 200 to perform multi-stage flotation on the lotus root powder slurry output by the fresh lotus root powder production system 100. This design can effectively grade and filter the lotus root powder slurry to ensure the particle size of the lotus root powder in the later stage and improve the taste of the food. At the same time, the unqualified lotus root powder is sent to the fresh lotus root powder production system 100 for secondary processing to improve the utilization rate of the raw materials and thus ensure the quality of the lotus root powder. Then, the lotus root powder gluing device 300 is used to add cold water to the lotus root powder wet particles discharged from the qualified product output end for gluing treatment, and the rotating shear force of stirring is used to make the lotus root powder slurry gelatinize, thereby avoiding precipitation in the subsequent transportation and processing process, reducing losses, and ensuring product output; the lotus root powder gelatinization device 400, the filling device 600 and the capping device 700 are used to heat, gelatinize, fill and cap the gelatinized lotus root powder in turn, thereby realizing automated production and ensuring production efficiency; the high-temperature disinfection device 800 is used to perform high-temperature disinfection on the packaged packaging boxes before leaving the factory to improve product quality.

[0049] See also Figure 1 to Figure 2In one embodiment of the present application, in order to improve the taste and fineness of the finished lotus root starch, the multi-stage cyclone sorting device 200 includes a primary cyclone 210, a secondary cyclone 220 and a tertiary cyclone 230. The feed end of the primary cyclone 210 is connected to the output end of the fresh lotus root starch production system 100, and the discharge end of the primary cyclone 210 is connected to the output end of the unqualified product; the overflow port of the primary cyclone 210 is connected to the feed end of the secondary cyclone 220 through a connecting pipe 240, and the discharge end of the secondary cyclone 220 is unidirectionally connected to the feed end of the primary cyclone 210; the secondary cyclone The overflow port of the device 220 is connected to the feed end of the third-stage cyclone 230 through a connecting pipe 240, and the overflow port of the third-stage cyclone 230 is connected to the qualified product output end; the discharge end of the third-stage cyclone 230 is unidirectionally connected to the feed end of the second-stage cyclone 220; a cyclone pressurizing mechanism 250 is provided on the connecting pipe 240, and the cyclone pressurizing mechanism 250 can cyclone pressurize the fluid flowing through the connecting pipe 240; a plurality of spiral guide grooves 241 are provided on the inner wall of one end of the connecting pipe 240 where the liquid is discharged; a normally closed discharge valve 260 is provided at the bottom of the second-stage cyclone 220 and the third-stage cyclone 230.

[0050] Among them, the feed port of the first-stage cyclone 210 is connected to the feed end of the slag-water separation device. Such a setting allows large lotus root powder particles to re-enter the slag-water separation device for filtration, and at the same time, part of the lotus root powder slurry can be recycled and reused; and by designing three different cyclones for step-by-step cyclone separation, the purpose is to ensure that the solid particles in the lotus root powder slurry flowing out of the overflow port of the three-stage cyclone 230 can all meet the particle size, avoiding the traditional need to dry the lotus root powder slurry and then grind it twice, and then re-add water for brewing, thereby simplifying the process and reducing production costs. In addition, as the lotus root powder slurry passes through the cyclone separation of each stage of the cyclone, the particle size specifications of the solid particles in the overflowing lotus root powder slurry gradually become the same in area. Therefore, in order to improve the separation capacity in the later stage, the main function of the cyclone pressurizing mechanism 250 is to facilitate the inflow speed of the lotus root powder slurry flowing into the cyclone of the next stage from the connecting pipe 240 to be increased. In the centrifugal field formed inside the cyclone, the centrifugal force on an object with a mass of m is: F = mv2 / r; where: m represents the mass of the particle; v represents the tangential velocity; r represents the radius of rotation. Therefore, when the inflow velocity increases, while the other structures of the cyclone are the same, the larger the centrifugal force received by the solid particles with relatively large particle sizes, the greater the separation of solid particles with similar particle sizes from the next level of cyclone. In fact, in the normal processing process, the cyclone can be directly used in two stages. The particle sizes of the solid particles in the lotus root powder slurry overflowed by the secondary cyclone 220 and the tertiary cyclone 230 are not much different. At this time, adding more tertiary cyclones 230 will obviously increase the manufacturing cost. Therefore, in the actual processing process, the number of cyclones is selected according to the actual product requirements.

[0051] In the above embodiment, the cyclone pressurizing mechanism 250 can be a conventional pressurizing pump structure, and a plurality of spiral guide grooves 241 are provided on the inner wall of one end of the connecting pipe 240 where the liquid is discharged, wherein the spiral guide grooves 241 are provided for the purpose of regulating the lotus root starch slurry discharged from the connecting pipe 240 and reducing its turbulence. At the same time, the lotus root starch slurry discharged from the connecting pipe 240 is provided with a self-rotating force, and when the lotus root starch slurry with a self-rotating force enters the cyclone of the next stage, it can be better subjected to cyclone separation, thereby accelerating the efficiency of cyclone separation.

[0052] In the above-mentioned improved embodiment, the swirl pressurizing mechanism 250 includes a housing 251 and a spiral shaft 252 rotatably installed in the housing 251. The portion of the spiral shaft 252 located in the housing 251 is spirally wound and the center of rotation forms a flow passage. The upper end of the housing 251 is provided with a feed pipe 253, and the lower end of the housing 251 is connected with a discharge pipe 254. The two ends of the flow passage are respectively connected with the feed pipe 253 and the discharge pipe 254; the outward ends of the feed pipe 253 and the discharge pipe 254 are respectively connected with the connecting pipe 240. One end of the spiral shaft 252 passes through the housing 251. A drive motor 255 is provided outside the housing 251. The drive motor 255 is connected to one end of the spiral shaft 252 passing through the housing 251. The spiral shaft 252 is actually a hollow spiral auger structure, and both ends thereof are provided with a concentric shaft structure, so that it can be installed and the spiral shaft 252 can be rotated. By designing a hollow core spiral auger, the impact of the lotus root starch slurry discharged from the previous cyclone on the spiral shaft 252 can be reduced. At the same time, the structural setting of the spiral shaft 252 can also increase and reduce the flow rate of the lotus root starch slurry to a certain extent. In addition, the shell 251 is cylindrical, and the feed pipe 253 and the discharge pipe 254 are tangent to the shell 251. Such a design can minimize the impact on the flow rate of the lotus root starch slurry. The feed pipe 253 and the discharge pipe 254 can be connected to the connecting pipe 240 by a joint, or in some embodiments, the feed pipe 253 and the discharge pipe 254 can be directly screwed on the shell 251 as part of the connecting pipe 240.

[0053] See also Figure 1 and 2 In one embodiment of the present application, in order to facilitate the subsequent gluing, the water body contained in the lotus root powder slurry discharged by the three-stage cyclone 230 is relatively large, and the water quality does not meet the requirements. At the same time, if the lotus root powder slurry is directly gelatinized, it will inevitably affect the quality of the finished lotus root powder in the later stage.

[0055] Among them, the rotary viscosity tester 370 is a conventional equipment and instrument in this application, and its main purpose is to facilitate the staff to check the viscosity of the lotus root starch slurry in the kettle 310. The cold water added in this application is actually cold boiled water, and its main purpose is to reduce the minerals in the filtered water body and improve the taste of lotus root starch in the later stage. At the same time, cold boiled water is relatively easy to obtain, and the production cost is low, which is low in the later stage cost compared to the current multi-stage filtered pure water. In addition, the lotus root starch slurry needs to maintain a certain temperature during the glue application process to improve the taste in the later stage. At the same time, the glue application operation can make the lotus root starch slurry experience extrusion at the same time, and the material is refined twice under the triple action of strong impact and pressure loss expansion, that is, the high shear force of the glue application mechanism 320 on the lotus root starch slurry is used to break the starch branches in the lotus root starch slurry, which is convenient for gelatinization in the later stage and improves the taste of the later product.

[0056] It should be noted that the purpose of the design of the vacuum mechanism 360 is to prevent the air inside the kettle 310 from oxidizing the lotus root starch slurry during the gluing process to ensure the quality of the lotus root starch. The vacuum mechanism 360 can be a conventional vacuum pump and the structure of the supporting pipeline and pump body, such as the structure in the vacuum mechanism of a food processor in patent CN201910774025.X, which is not described in detail in this application.

[0060] In the above-mentioned embodiment, the packaging box is stacked on the automatic stacking mechanism 520 of the packaging box, and such a setting is mainly for facilitating the cleaning and hot air drying of the packaging box. The packaging box can be a conventional aluminum-plastic packaging box, or a conventional plastic or metal packaging box. In this application, in order to avoid water accumulation and facilitate the washing and drying of the packaging box, the conveyor chain 530 is a mesh chain structure in this application, such as the structure in the patent CN201821869696.1-a top roller chain conveyor hanger, so that the packaging box can be directly washed upward by the washing mechanism 540 when it is buckled on the conveyor chain 530.

The applicant will not elaborate on this.

[0061] See also Figure 7 and Figure 8In one embodiment of the present application, in order to simplify the structure, the flip mechanism 560 includes an arc-shaped guide pressure plate 561 and a receiving and positioning seat 562. The arc-shaped guide pressure plate 561 is installed on the frame 510 and is concentrically arranged with the rotation center on the output end of the conveyor chain 530. The output end of the arc-shaped guide pressure plate 561 is located below the output end of the conveyor chain 530. The two sides of the output end of the arc-shaped guide pressure plate 561 are respectively provided with arc-shaped bearing guide rods 563. The two bearing guide rods 563 can cooperate with each other to support both sides of the packaging box, the two bearing guide rods 563 are eccentrically arranged with the rotation center on the output end of the conveyor chain 530 and the lower ends gradually move away from the back side of the output end of the conveyor chain 530, and the receiving and positioning seat 562 is installed on the area of ​​the frame 510 below the back side of the conveyor chain 530, and the receiving and positioning seat 562 can receive the packaging boxes output by the two bearing guide rods 563, and the packaging boxes on the receiving and positioning seat 562 can be delivered to the filling device 600.

[0062] When the inverted packaging box is conveyed to one end of the arc-shaped guide pressing plate 561 along with the conveying chain 530, due to the limiting effect of the arc-shaped guide pressing plate 561 and the conveying force of the conveying chain 530, the packaging box is clamped between the conveying chain 530 and the arc-shaped guide pressing plate 561, and can also move with the conveying chain 530. A shock-absorbing spring is arranged between the arc-shaped guide pressing plate 561 and the frame 510. After the packaging box is clamped and conveyed by the conveying chain 530 and the arc-shaped guide pressing plate 561, the packaging box is driven to the space between the conveying chain 530 and the bearing guide rod 563. At this time, the packaging box is almost turned over. At this time, the packaging box will adjust itself according to its own gravity and the overall weight will gradually transfer to the two bearing guide rods 563. Since the two bearing guide rods 563 are eccentrically arranged at one end corresponding to the conveying chain 530, and the lower end of the bearing guide rod 563 gradually moves away from the conveying chain 530, the packaging box gradually slides down on the two bearing guide rods 563 due to its own weight until it is received by the receiving and positioning seat 562. The receiving and positioning seat 562 can be a steering structure, such as a guide frame, which is convenient for steering the packaging box and adapting to the packaging box input end of the filling device 600.

Among them, the mounting seat 565 is provided with a plug hole, the connecting column 566 is movably inserted in the plug hole, and the shock absorbing spring 567 is fixedly installed with the step and the mounting seat 565. Of course, in some embodiments, the end of the connecting column 566 that is not connected to the arc-shaped guide pressure plate 561 can be locked and fixed to the other side of the mounting seat 565 by a nut.

[0065] In order to receive the packaging boxes discharged by the two bearing guide rods 563 and to move the packaging boxes downward to the input end of the filling device 600, in one embodiment of the present application, the receiving and positioning seat 562 includes a seat body 568 and a pair of receiving rods 569 arranged on the seat body 568, the seat body 568 is connected to the frame 510, and the pair of receiving rods 569 can receive the packaging boxes discharged by the two bearing guide rods 563; an elastic portion 56a is arranged between the receiving rod 569 and the seat body 568, and the elastic portion 56a can be deformed and reset. When the two receiving rods 569 cooperate to clamp the packaging box, the packaging box can bend the elastic portion 56a. The elastic portion 56a can be a spring structure or a rubber strip with a steel wire arranged inside. The seat body 568 can be installed and fixed on the frame 510 by screws.

Of course, in some embodiments, a limiting guardrail can be set on both sides of the secondary conveyor belt 620, and the secondary conveyor belt 620 can be driven to rotate by a servo motor at the same time, so that the control posture of the packaging box is adjusted by the limiting guardrail, and then the servo motor rotates a certain number of times each time so that each packaging box can stop just below the lifting quantitative filling mechanism 630, so as to cooperate with the lifting quantitative filling mechanism 630 for filling. In addition, a position sensor is arranged on the bracket 610 for detecting the packaging boxes on the secondary conveyor belt 620, so as to control the actions of the secondary conveyor belt 620, the lifting quantitative filling mechanism 630 and the two positioning clamping mechanisms 640. It should be noted that the two positioning clamping mechanisms 640 can clamp multiple packaging boxes at the same time, so as to perform simultaneous filling by the lifting and lowering quantitative filling mechanism 630, thereby improving the filling efficiency.

The temporary storage tank 631 is used to receive and temporarily store the gelatinized lotus root starch discharged by the lotus root starch gelatinization device 400, and the gelatinized lotus root starch in the temporary storage tank 631 can automatically flow into all the filling tubes 634. The temporary storage tank 631 is connected with the gelatinized lotus root starch through a pipeline, and a supply pump is arranged on the pipeline. When the packaging box is in place, the two positioning clamping mechanisms 640 extend at the same time and clamp the opposite sides of the packaging box, and the lifting mechanism 633 extends and drives the lifting seat 632 to descend, so that all the filling tubes 634 can be driven to descend for filling. In order to improve the efficiency of filling, the present application can simultaneously fill multiple packaging boxes, thereby improving the efficiency of filling. The lifting mechanism 633 can be a conventional screw motor structure or a telescopic electric cylinder structure.

[0069] The present invention also provides a method for producing canned lotus root starch, comprising the following steps:

[0070] Fresh lotus root powder processing: the harvested fresh lotus roots are sequentially rinsed, sectioned and soaked, and then processed by a fresh lotus root peeling and cleaning device and a fresh lotus root crushing and grinding device, and then the lotus root powder slurry is obtained after the residue and water are separated;

[0071] Multi-stage cyclone sorting: using multiple cyclone sorting devices to perform multi-stage cyclone circulation sorting on the lotus root starch slurry, respectively obtaining unqualified products and qualified products, the unqualified products are sent to the fresh lotus root crushing and grinding device for secondary grinding, and the qualified products are sent to the next process after being drained;

[0072] Stirring and gluing: Add the drained qualified product and cold boiled water into the lotus root starch gluing device 300 for stirring, the stirring temperature is room temperature, and the stirring process is stirred in a vacuum state or under a normal pressure protective gas environment; the initial mass ratio of the drained qualified product to the cold boiled water is 1:1-2; during the stirring process, cold boiled water is gradually added as the viscosity of the mixture increases, and when the dynamic viscosity of the mixture is greater than 5 Pa.s, the stirring is stopped, and the final total mass ratio of the drained qualified product to the cold boiled water is 1:2-4, so as to obtain gelatinized lotus root starch;

[0073] Gelatinized lotus root powder: the gelatinized lotus root powder is fed into a heating kettle 410 for stirring and heating, and auxiliary materials with a preset mass ratio are added during the stirring and heating process according to the mass of the gelatinized lotus root powder. The heating temperature is 90-100° C., the heating pressure is normal pressure, and the stirring and heating time is 10-60 min. After the gelatinized lotus root powder is completely gelatinized, the gelatinized lotus root powder is obtained, and the gelatinized lotus root powder is cooled and naturally exhausted until the temperature of the gelatinized lotus root powder drops below 40° C.

[0074] Filling lotus root starch: sending the gelatinized lotus root starch that has been cooled and degassed into the filling device 600 for filling, and then using the capping device 700 to sequentially cap and screw-cap the packaging boxes discharged from the filling device 600;

[0075] Factory processing: The filled packaging boxes are treated with high temperature before they can be shipped out of the factory, completing the production of canned lotus root starch.

[0076] Among them, in the step of processing fresh lotus root powder, the fresh lotus root crushing and grinding device can crush and grind the fresh lotus root residue and slurry after the initial crushing at least twice. Such a setting is mainly to improve the fineness of the entire lotus root powder slurry, thereby ensuring the output of lotus root powder. In the step of multi-stage cyclone sorting in the above embodiment, the entry speed of the multi-stage cyclone sorting is gradually increased step by step. Such a purpose is to facilitate the improvement of product quality and ensure the delicate taste of lotus root powder. In addition, in this step, in order to adapt to different grades of lotus root powder slurry, different lotus root powder glue devices 300 can be directly connected to the overflow ports of different cyclones. Such a purpose can enable the same set of cyclone equipment to produce lotus root powder of different particle sizes. In the step of stirring and gluing, stirring and gluing can be carried out in a low temperature environment to avoid the heat generated during the stirring and gluing process causing the lotus root powder slurry to be partially gelatinized. Of course, in the actual production process, stirring and gluing can also be carried out at room temperature. Although this will reduce the taste of the product, it can also reduce production costs.

[0077] In addition, in the above-mentioned step of gelatinizing lotus root powder, it can be heated and gelatinized completely at one time, or it can be preliminarily gelatinized, which is convenient for filling in the step of filling lotus root powder and reducing the oxidation of lotus root powder by air; and then in the step of factory processing, it can be fully gelatinized for a second time while being sterilized at high temperature. Of course, the above-mentioned processing technology and the aforementioned processing technology of this application can be selected according to actual processing needs. After the step of factory processing, there are also detection steps, such as metal detection, air tightness detection, etc., and there are also steps for packaging and warehousing levels, which are set according to actual usage needs.

[0078] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
