Description

Technical Field

[0001] This invention belongs to the field of production technology, and in particular relates to a continuous rice-moistening production line. Background Technology

[0002] In traditional zongzi (sticky rice dumpling) making, soaking the rice (also known as rinsing or soaking) is a crucial pre-processing step that determines the taste and quality of the finished product. Glutinous rice needs to be thoroughly washed and drained, then softened by absorbing water under specific time and conditions. During this process, salt, soy sauce, cooking oil, or other flavorings are usually added and mixed to ensure even flavoring, plump grains, and good steaming and cooking adaptability. However, current production still commonly uses manual or semi-mechanized methods for soaking rice: workers pour the washed glutinous rice into containers to drain naturally, then manually add seasonings and stir, followed by soaking for several hours. Although some companies have tried to introduce equipment such as mixers or conveyor belts to assist in soaking, these devices often operate in isolation. For example, a rice washing machine is used to initially remove impurities from the rice, which is then naturally drained via a vibrating screen or mesh belt. However, these systems generally suffer from the following problems: fragmented processes; washing, draining, soaking, and seasoning are mostly done with independent equipment, requiring manual transfer or temporary storage, resulting in inconsistent production rhythms and making it difficult to achieve truly continuous operation.

[0033] like Figures 1-18 As shown, this embodiment provides a fully automatic continuous fried rice production line, which includes a rice washing module 20, a draining module 30, a stirring and moistening module 40, and a temporary storage module 50 arranged in sequence. After being washed, the rice is drained by the draining module 30 and then enters the stirring and moistening module 40. The seasoning module 10 next to the stirring and moistening module 40 adds seasonings to the stirring and moistening module 40. The stirred rice is then transported to the temporary storage module 50 for storage, realizing a continuous production process from raw rice to rice moistening and temporary storage.

[0034] The rice washing module 20 includes a rice hopper metering machine and a rice washing machine. The rice hopper metering machine controls the volume of raw rice output per batch; the rice washing machine performs the washing operation on the raw rice to remove impurities from its surface.

[0035] The rice washing module can adopt a mature equipment structure with the same function in the existing technology, so it will not be described in detail here.

[0036] Specifically, the draining module 30 includes a draining conveying device, which includes a draining frame 3100, a support, an extension, a draining section, and a water receiving plate 3401.

[0037] Specifically, the support section includes a support plate 3200 fixed to the drain frame 3100, and a plurality of first drain holes 3201 are arrayed on the support plate 3200 for drainage; the extension section includes an extension plate 3300 that can slide and adjust along the drain frame 3100. The extension plate 3300 is located at the discharge end of the support plate 3200 and partially overlaps with the support plate 3200 in the vertical direction to ensure that the drain mesh belt 3400 continuously covers without any breaks.

[0038] The drain section uses a drain mesh belt 3400 with a mesh diameter smaller than that of a grain of rice. The drain mesh belt 3400 surrounds the support plate 3200 and the extension plate 3300 to form a continuous conveying surface. A water receiving plate 3401 is located directly below the support section and the extension section to collect water discharged from the mesh belt and drain holes, and guide it to the drain outlet or recycling system.

[0039] In actual use, after the rice is washed, it is fed onto the draining mesh belt 3400. Under the action of gravity, the water quickly passes through the mesh and the draining holes on the support plate 3200, and falls into the water receiving plate 3401 below for discharge. At the same time, the rice grains are conveyed forward with the mesh belt. At this time, the operator can adjust the extension length of the extension plate 3300 according to the position of the subsequent process (such as the mixing drum or the fried rice drum), so that the end of the draining mesh belt 3400 extends directly into the inlet of the mixing drum.

[0040] Specifically, the support plate 3200 has multiple parallel and equally spaced strip-shaped protrusions 3202 along the conveying direction (i.e., the length direction), with recesses 3203 naturally formed between adjacent protrusions 3202; several first drainage holes 3201 are concentrated at the bottom of each recess 3203, forming the main drainage channel; the extension section includes an extension plate 3300 that can slide horizontally along the draining frame 3100, and its structure is completely consistent with that of the support plate 3200: it also has protrusions 3202 and recesses 3203 extending along the length direction. In practical applications, the wet rice discharged from the rice washing machine falls into the starting end of the draining mesh belt 3400. Since both the support plate 3200 and the extension plate 3300 adopt an alternating convex-concave structure, the rice grains mainly stay on the top of the convex part 3202, avoiding direct pressure on the drain hole; the rice washing water quickly passes through the mesh belt, flows into the lower concave part 3203 under the action of gravity, and is efficiently discharged through the first drain hole 3201.

[0041] In actual operation, the wet rice discharged from the rice washing machine falls into the feed end (lower end) of the draining mesh belt 3400. Because the entire conveyor surface is inclined upward, the rice grains are conveyed upward against the gravity component under the drive of the mesh belt, prolonging the residence time and improving the draining effect; at the same time, the washing water flows rapidly downward (i.e., in the opposite direction to the discharge direction) under the action of gravity, passes through the mesh belt and falls into the water receiving plate 3401, which is also inclined below, and naturally collects into the water receiving tank 3402 at its lower end for centralized treatment or recycling.

[0042] Several tension rollers 3101 are fixedly installed on the dewatering frame 3100 to maintain the basic tension of the dewatering mesh belt 3400; at the same time, at least one adjusting roller 3102 is provided, the installation position of which can be adjusted by a chute, guide rail or linkage mechanism; the dewatering mesh belt 3400 passes around the tension rollers 3101 and the adjusting roller 3102 in sequence to form a closed loop; when the extension part moves forward or backward to adjust the conveying length, the adjusting roller 3102 can move synchronously and in linkage to compensate for the changes in mesh belt tension caused by the change in extension length, and always maintain a suitable tension;

[0043] A drive unit 3103 (such as a geared motor or servo motor) is fixedly installed on the drain frame 3100, and its output shaft is rigidly connected to the extension part. A sliding part 3104 (such as a slider or slide rail base) is provided at the bottom of the extension part, and a guide part 3105 (such as a linear guide rail) is correspondingly provided on the drain frame 3100. The sliding part 3104 and the guide part 3105 form a sliding fit pair, ensuring that the extension part moves smoothly and linearly in a predetermined direction (i.e., the discharge direction) under the drive of the drive unit 3103, without shaking or jamming. An adjusting roller 3102 is fixed on the sliding part 3104. Therefore, when the drive unit 3103 drives the extension part to move, the sliding part 3104 slides synchronously, and the adjusting roller 3102 moves in conjunction with the extension part.

[0044] When the drive unit 3103 is activated, it pushes the extension section forward along the guide section 3105. Simultaneously, the adjusting roller 3102 moves forward synchronously with the extension section, dynamically adjusting the mesh belt's envelope path so that the drain mesh belt 3400 always adheres to the surfaces of the protrusions 3202 on the support plate 3200 and the extension plate 3300. Even at maximum extension, the mesh belt maintains uniform tension, ensuring smooth conveying, accurate alignment of the drain holes, and unobstructed drainage.

[0045] Furthermore, a water-blocking surface (connecting plane) is provided on the upper surface of the outer end region of the extension plate 3300 (i.e., the part near the free end). The main function of the water-blocking surface is to intercept the residual water carried with the rice grains when the draining mesh belt 3400 conveys wet rice to the end of the extension plate 3300, preventing it from continuing to flow outward and dripping from the front end of the extension plate 3300.

[0046] When the extension plate 3300 is pushed to its maximum extension position by the drive unit 3103 (e.g., fully extended into the mixing drum inlet), the projection of the water-blocking surface in the vertical direction overlaps with the projection area of ​​the water-receiving plate 3401 located below it. Since the water-receiving plate 3401 is also inclined upward along the discharge direction and covers the area directly below the support and extension parts, this projection overlap ensures that any water dripping from the edge of the water-blocking surface or flowing down its surface will fall vertically under the action of gravity and will inevitably fall into the effective collection range of the water-receiving plate 3401, and will eventually be guided by the water-receiving plate 3401 to the water-receiving tank 3402 at the lower end. Thus, even if the extension plate 3300 is fully extended and suspended in the air, the water in its end area is forcibly constrained by the structure within the controlled drainage path and cannot leak to the ground or outside the equipment.

[0047] In another specific embodiment, the extension section includes an extension plate 3300 slidably disposed at the discharge end of the support plate 3200. The overall structure of the extension plate 3300 is similar to that of the support plate 3200, also having protrusions 3202 and recesses 3203 extending along the length direction. The difference is that a plurality of second drainage holes 3301 are linearly distributed on the protrusions 3202 of the extension plate 3300, the diameter of which is smaller than the diameter of the first drainage holes 3201 on the support plate 3200. This design aims to perform secondary fine drainage on the initially drained rice grains, preventing rice grains from getting stuck or clogging due to excessively large hole diameters; at the same time, a plurality of third drainage holes 3302 are also provided at the bottom of the recess 3203 near the end of the extension plate 3300 close to the support plate 3200. This area is where the support plate 3200 and the extension plate 3300 meet, and residual water is prone to accumulate. The third drainage hole 3302 can effectively drain the water in this area and prevent water from flowing back or accumulating.

[0048] This device further includes a conveying section 3500, which is fixedly disposed above the end of the support plate 3200 away from the extension plate 3300 (i.e., the feeding end), for receiving wet rice from the rice washing equipment and completing preliminary draining and directional flow. The conveying section 3500 includes a draining chamber 3501, and a draining plate 3502 is fixed to the upper part of the draining chamber 3501 for receiving wet rice and performing preliminary draining. The draining plate 3502 is inclined towards a first direction in a vertically downward extending direction. A water guiding plate 3503 is located directly below the draining plate 3502 for receiving rice washing water falling from the draining plate 3502. The water guiding plate 3503 is inclined towards a second direction in a vertically downward extending direction, and the second direction is opposite to the first direction on the horizontal plane. This creates a spatially misaligned double-sloped structure: rice grains roll along the drain plate 3502 in the first direction and fall into the conveying cavity 3504 formed below through the gap between the edge of the drain plate 3502 and the inner wall of the drain cavity 3501, eventually sliding down to the starting end of the drain mesh belt 3400; while the water leaking from the holes of the drain plate 3502 drips onto the surface of the water guide plate 3503 under the action of gravity, and then flows along its reverse (second direction) inclined surface to the drain outlet on the other side of the drain cavity 3501 or directly into the main water receiving system.

[0049] Based on the aforementioned drain conveying device, baffles 3106 are fixedly installed on both sides (i.e., the left and right edges along the conveying width direction) of the support plate 3200 and the extension plate 3300. The baffles 3106 are vertical or slightly outwardly inclined plate-like structures extending parallel to the length of the plate, with a height higher than the top of the protrusion 3202. When the extension plate 3300 is in any extended position (including its extreme position), the baffles 3106 on it and the baffles 3106 on the support plate 3200 remain continuous in the overlapping area, ensuring that both sides of the drain conveyor belt 3400 are always effectively blocked.

[0050] The drain mesh belt 3400 is fitted on the protrusion 3202 of the support plate 3200 and the extension plate 3300, and is located between the two baffles 3106 to form a closed conveying channel.

[0051] Specifically, the seasoning equipment includes:

[0052] A quantitative dispensing device 100 and a seasoning dissolving device 200 are arranged along the dispensing direction of the seasoning. The seasoning dissolving device 200 dissolves the quantitative seasoning output from the quantitative dispensing device 100. The seasoning dissolving device 200 includes:

[0053] Support 210 serves as a supporting structure;

[0054] A seasoning dissolving tank 220 is placed on a support 210, and a dissolving chamber 221 is provided on the seasoning dissolving tank 220. The opening of the dissolving chamber 221 faces the quantitative dispensing device 100. The seasoning dissolving tank 220 is provided with an inlet channel 222 for inputting liquid before seasoning and an outlet channel 223 for outputting liquid after seasoning.

[0055] The stirring module 230 includes a stirring motor 231 mounted on the seasoning dissolving tank 220, and the output end of the stirring motor 231 is connected to a stirring shaft 232, which extends into the seasoning dissolving tank 220. The stirring shaft 232 has a plurality of stirring blades 233 arranged in a ring on it, and the stirring blades 233 include a first driving part 2331 that enables the liquid in the seasoning dissolving tank 220 to move in a spiral shape, and a second driving part 2332 that enables the liquid in the seasoning dissolving tank 220 to move up and down in a rolling motion.

[0056] The present invention provides a quantitative stirring seasoning device, which, through the first driving part 2331 and the second driving part 2332 on the stirring blade 233, not only realizes the spiral motion of the liquid, but also realizes the up-and-down tumbling motion, so that the seasoning in the seasoning dissolving tank 220 is always in motion and cannot sink to the bottom, thereby improving the dissolving effect of the seasoning.

[0057] Furthermore, the first drive unit 2331 and the second drive unit 2332 are arranged in a planar manner, and the first drive unit 2331 includes a first side connected to the side wall of the stirring shaft 232 and a second side connected to the second drive unit 2332. The extension direction of the first side is not parallel to the axial direction of the stirring shaft 232, and the second side extends obliquely downward along the direction close to the bottom of the dissolving chamber 221 to form the second drive unit 2332.

[0058] It is worth mentioning that, since the extension direction of the first side is not parallel to the axial direction of the stirring shaft 232, the first driving part 2331 is obliquely connected to the outer wall of the stirring shaft 232, while the second side extends obliquely downward along the direction close to the bottom of the dissolving chamber 221 to form the second driving part 2332, so that the angle formed between the first driving part 2331 and the second driving part 2332 is an obtuse angle. The stirring blade 233 forms the first driving part 2331 and the second driving part 2332 by bending.

[0059] In this embodiment, since the angle between the first driving part 2331 and the second driving part 2332 is an obtuse angle, the stirring shaft 232 can "scoop up" the liquid near the bottom of the dissolving chamber 221 during the circumferential rotation, so that the liquid at the bottom of the dissolving chamber 221 tends to move towards the opening of the dissolving chamber 221, thereby realizing the up-and-down rolling of the liquid and improving the dissolution rate of the seasoning.

[0060] Preferably, the feeding channel 222, the discharging channel 223, and the stirring module 230 are all located at the bottom of the seasoning dissolving tank 220. The discharging end of the feeding channel 222 is located at the bottom of the dissolving chamber 221 and is connected to the dissolving chamber 221. The feeding end of the discharging channel 223 is located at the bottom of the dissolving chamber 221 and is connected to the dissolving chamber 221. The stirring shaft 232 in the stirring module 230 extends from the bottom of the dissolving chamber 221 into the dissolving chamber 221. A liquid level sensor 224 is provided on the wall of the dissolving chamber 221.

[0061] It is worth mentioning that the feeding channel 222 is set at the bottom of the seasoning dissolving tank 220, so that the liquid level in the seasoning dissolving tank 220 gradually rises from low to high, improving the accuracy of the liquid level sensor 224 in measuring the liquid level height. The discharge channel 223 is set at the bottom of the seasoning dissolving tank 220, so that the seasoned liquid can be completely discharged, avoiding the liquid residue in the seasoning dissolving tank 220, which would affect the accuracy of the next seasoning. In addition, the stirring module 230 is set at the bottom of the seasoning dissolving tank 220. On the one hand, it avoids assembly interference with the quantitative discharge device 100 above the seasoning dissolving tank 220, and on the other hand, it can further prevent the seasoning from settling to the bottom, thus improving the seasoning dissolving effect.

[0062] Preferably, the quantitative discharging device 100 includes:

[0063] The seasoning frame 110 has a first mounting surface, a second mounting surface, and a third mounting surface arranged sequentially along the direction of seasoning discharge;

[0064] A seasoning storage tank 120 is inverted on the seasoning machine frame 110, and the tank body of the seasoning storage tank 120 is installed on the first mounting plane, and the opening of the seasoning storage tank 120 extends to the second mounting plane. The seasoning storage tank 120 is used to store seasonings.

[0065] A variable volume module 130 is located between a second mounting plane and a third mounting plane, and the variable volume module 130 is horizontally slidable between the second mounting plane and the third mounting plane. The variable volume module 130 includes:

[0066] The telescopic bracket can extend and retract along the direction of seasoning dispensing. Each end of the telescopic bracket along the extension direction is provided with two through holes. The through hole facing the second mounting plane is the first through hole 1334, and the through hole facing the third mounting plane is the second through hole 1344. The distance between the two first through holes 1334 is equal to the distance between the two second through holes 1344, and the positions of the two first through holes 1334 and the positions of the two second through holes 1344 correspond one-to-one.

[0067] Two seasoning measuring containers 131 are mounted on a telescopic bracket. The two ends of each seasoning measuring container 131 in the axial direction are respectively connected to the corresponding first through hole 1334 and second through hole 1344. The seasoning measuring container 131 includes two nested and coaxially arranged sleeves, namely the first sleeve 1311 and the second sleeve 1312.

[0068] The lifting bracket 132 is located below the telescopic bracket and supports the telescopic bracket. The lifting bracket 132 moves up and down along the direction of seasoning drop to change the overlap area between the first sleeve 1311 and the second sleeve 1312. The lifting bracket 132 is provided with two third through holes 1321, and the distance between the two third through holes 1321 is twice the distance between the two first through holes 1334. When one of the two seasoning metering tanks 131 is connected to one of the two third through holes 1321, the other seasoning metering tank 131 is connected to the opening of the seasoning storage tank 120 and is offset from the other of the two third through holes 1321.

[0069] It is worth mentioning that, since each seasoning measuring container 131 is composed of two nested sleeves, and the two sleeves are retractable, when the two sleeves move in opposite directions along the axial direction, the overlapping area of ​​the two sleeves decreases, which increases the volume of the entire seasoning measuring container 131, thereby increasing the amount of seasoning that can be stored in the seasoning measuring container 131; when the two sleeves move towards each other along the axial direction, the overlapping area of ​​the two sleeves increases, which decreases the volume of the entire seasoning measuring container 131, thereby reducing the amount of seasoning that can be stored in the seasoning measuring container 131.

[0070] It is worth mentioning that the number of seasoning metering tanks 131 is set to two, so that when the seasoning in one seasoning metering tank 131 is dispensed, the other seasoning metering tank 131 can be connected to the opening of the seasoning storage tank 120, thereby realizing the pre-storage of seasoning, ensuring the continuity of seasoning addition and improving work efficiency.

[0071] In this embodiment, the quantitative dispensing device 100 can adjust the volume of the seasoning dispensing container 131 according to the amount of seasoning required for cooking the ingredients, thereby ensuring the taste of the cooked ingredients and improving the user experience. Furthermore, the quantitative dispensing device 100 in this invention can add seasoning twice in one reciprocating motion, improving work efficiency compared to traditional seasoning dispensing methods.

[0072] More preferably, the telescopic support includes an upper cover 133 and a lower base 134 arranged along the seasoning feeding direction, and the upper cover 133 and the lower base 134 are inserted into each other. Two seasoning measuring containers 131 are sandwiched between the upper cover 133 and the lower base 134, and the two ends of the seasoning measuring containers 131 along the axial direction are respectively connected to the upper cover 133 and the lower base 134. The telescopic direction of the seasoning measuring containers 131 is consistent with the telescopic direction of the telescopic support.

[0073] It is worth mentioning that the upper cover 133 includes an upper sliding plate 1331 that slides and cooperates with the second mounting plane, and an upper moving frame 1332 connected to the upper sliding plate 1331, and an upper receiving cavity 1333 is provided on the upper moving frame 1332; the lower bottom 134 includes a lower sliding plate 1341 that slides and cooperates with the third mounting plane, and a lower moving frame 1342 connected to the lower sliding plate 1341, and a lower receiving cavity 1343 is provided on the lower moving frame 1342. The opening direction of the upper receiving cavity 1333 is opposite to the opening direction of the lower receiving cavity 1343, and the upper moving frame 1332 and the lower moving frame 1342 are inserted and cooperated. Two seasoning measuring containers 131 are sandwiched between the upper moving frame 1332 and the lower moving frame 1342, and are connected to the upper moving frame 1332 and the lower moving frame 1342.

[0074] In addition, a first through hole 1334 provided on the upper cover 133 passes through the upper slide plate 1331 and the upper moving frame 1332, and a second through hole 1344 provided on the lower bottom 134 passes through the lower slide plate 1341 and the lower moving frame 1342.

[0075] In this embodiment, the upper moving frame 1332 and the lower moving frame 1342 are arranged with opposite opening directions and are inserted into each other, so that when the two sleeves move relative to each other, the insertion position between the upper moving frame 1332 and the lower moving frame 1342 can serve as a guide part, so that the movement of the two always moves along the axial direction, ensuring the smoothness of their movement.

[0076] More preferably, in order to ensure the consistency between the extension and retraction of the seasoning dispenser 131 and the extension and retraction of the telescopic support, and to ensure that the dimensions of both do not change automatically after extension and retraction, a telescopic structure 135 is provided between the upper cover 133 and the lower bottom 134. There can be multiple telescopic structures 135, which are distributed on each corner of the telescopic support. The two ends of the telescopic structure 135 along the extension and retraction direction are connected to the upper cover 133 and the lower bottom 134, respectively.

[0077] It is worth mentioning that the telescopic structure 135 can be two nested telescopic rods, and there is a damping structure between the two telescopic rods. By setting the damping structure, the volume of the seasoning metering container 131 will not change automatically after the volume change, thus improving the reliability of the variable volume module 130.

[0078] Preferably, the second mounting plane of the seasoning rack 110 is provided with two parallel first connecting plates 111, and a first slide rail 112 is connected to the first connecting plate 111, wherein the upper cover 133 is slidably attached to the first slide rail 112; the third mounting plane of the seasoning rack 110 is provided with two parallel second connecting plates 113, and a second slide rail 114 is connected to the second connecting plate 113, wherein the lifting bracket 132 is clamped between the two second slide rails 114, and the lifting bracket 132 is connected to the second connecting plate 113 through the adjusting structure 136.

[0079] It is worth mentioning that the second connecting plate 113 is L-shaped, the bending directions of the two second connecting plates 113 are opposite, and the second slide rail 114 is connected to the vertically arranged side of the second connecting plate 113. The lifting bracket 132 is connected to the horizontally arranged side of the second connecting plate 113 through the adjustment structure 136. There is an adjustable gap between the lifting bracket 132 and the horizontally arranged side of the second connecting plate 113.

[0080] Furthermore, the adjusting structure 136 includes a screw 1361, and a movable nut 1362 is screwed onto the screw 1361. A fixed nut 1363 is riveted to one side of the second connecting plate 113 that is horizontally arranged. One end of the screw 1361 passes through the fixed nut 1363 and abuts against the lifting bracket 132. When the movable nut 1362 is rotated to abut against the fixed nut 1363, the adjustable gap between the lifting bracket 132 and the horizontally arranged side of the second connecting plate 113 is locked.

[0081] When it is necessary to adjust the volume of the seasoning dispenser 131, release the contact between the movable nut 1362 and the fixed nut 1363, and then turn the screw 1361 to move the lifting bracket 132 up and down along the direction of seasoning discharge. This causes the lower base 134, which is supported on the lifting bracket 132, to also move up and down along the direction of seasoning discharge, thereby changing the relative distance between the lower base 134 and the upper cover 133, thus changing the volume of the seasoning dispenser 131. After the volume of the seasoning dispenser 131 is adjusted, turn the movable nut 1362 again to make the movable nut 1362 abut against the fixed nut 1363 to lock it in place.

[0082] More preferably, the lifting bracket 132 includes a lifting plate 1322 and a lifting leg 1323 connected to the lifting plate 1322, wherein one end of the screw 1361 passes through the horizontally positioned side of the second connecting plate 113 and abuts against the lifting leg 1323.

[0083] Preferably, one of the two first connecting plates 111 is equipped with a translation mechanism 140 for driving the reciprocating movement of the variable volume module 130, and the translation mechanism 140 includes a translation cylinder 141, and the output end of the translation cylinder 141 is connected to the upper cover 133 through the translation plate 142. The reciprocating movement of the entire variable volume module 130 is driven by the extension and retraction of the output end of the translation cylinder 141, via the translation plate 142 and the upper cover 133.

[0084] Preferably, the system further includes a feeding mechanism located below the variable volume module 130. This feeding mechanism includes an opening and closing structure 150 connected to the lifting bracket 132 and corresponding to the position of the third through hole 1321, and a triggering structure 160 disposed on the lower bottom 134 for triggering the opening and closing structure 150 to open or close. When the distance between the axes of the two seasoning metering tanks 131 and the axis of the opening of the seasoning storage tank 120 is equal, no compression occurs between the triggering structure 160 and the two opening and closing structures 150. When the distance between the axes of the two seasoning metering tanks 131 and the axis of the opening of the seasoning storage tank 120 is not equal, the triggering structure 160 compresses the opening and closing structure 150 on the side of the two seasoning metering tanks 131 that is farther from the opening of the seasoning storage tank 120, while the opening and closing structure 150 on the side of the two seasoning metering tanks 131 that is farther from the opening of the seasoning storage tank 120 is in a closed state.

[0085] In this embodiment, during the quantitative feeding process, the opening and closing structure 150 not only prevents liquid seasonings such as soup or braising liquid from splashing into the seasoning metering tank 131, but also prevents moisture from the heated liquid from entering the seasoning metering tank 131, causing the seasonings to become damp and stick to the seasoning metering tank 131, thus reducing the accuracy of the quantitative feeding.

[0086] It is further pointed out that one end of the trigger structure 160 connected to the lower bottom 134 is located on the axis of symmetry between the two seasoning dispensing containers 131.

[0087] In the initial state, the opening of the seasoning storage tank 120 can be located between the two seasoning measuring tanks 131, that is, neither of the two seasoning measuring tanks 131 is connected to the seasoning storage tank 120. At this time, the opening of the seasoning storage tank 120 is abutted against the area between the two first through holes 1334, so that the opening of the seasoning storage tank 120 is in a closed state. Therefore, the seasoning in the seasoning storage tank 120 will not fall automatically. Furthermore, since the distance between the two seasoning dispensers 131 is equal to the distance between the two first through holes 1334 or the distance between the two second through holes 1344, and the distance between the two third through holes 1321 is twice the distance between the two first through holes 1334, and the distance between the two third through holes 1321 is equal to the distance between the two opening and closing structures 150, the two seasoning dispensers 131 are located between the two opening and closing structures 150. Moreover, the trigger structures 160 connected to the lower bottom 134 do not contact the two opening and closing structures 150; therefore, both opening and closing structures 150 are in a closed state. At this time, neither seasoning dispenser 131 contains any pre-stored seasoning.

[0088] For clarity and convenience, the left one of the two seasoning measuring containers 131, the two opening and closing structures 150, and the two third through holes 1321 is referred to as the left seasoning measuring container 131, the left opening and closing structure 150, and the left third through hole 1321, respectively. The right one of the two seasoning measuring containers 131, the two opening and closing structures 150, and the two third through holes 1321 is referred to as the right seasoning measuring container 131, the right opening and closing structure 150, and the right third through hole 1321, respectively.

[0089] When it is necessary to transfer the seasonings from the seasoning storage tank 120 to the left seasoning metering tank 131, the variable volume module 130 moves horizontally to the right, causing the left seasoning metering tank 131 to gradually approach the seasoning storage tank 120. When the left seasoning metering tank 131 and the seasoning storage tank 120 begin to connect, the seasonings in the seasoning storage tank 120 enter the left seasoning metering tank 131. Since the trigger structure 160 is located on the bottom 134, it also moves horizontally to the right along with the movement of the variable volume module 130. During the movement, the trigger structure 160 gradually triggers the right opening and closing structure 150, causing the right opening and closing structure 150 to gradually open. When the left seasoning storage tank 120 is completely aligned with the opening of the seasoning storage tank 120, that is, when the two are coaxially arranged, At this time, the right seasoning metering container 131 is connected to the third through hole 1321 on the right, and the right opening and closing structure 150 is opened to the maximum state. Since there is no seasoning in the right seasoning metering container 131, no seasoning falls even though the right opening and closing structure 150 is open. The left seasoning metering container 131 is connected to the seasoning storage container 120, so a certain amount of seasoning is stored in the left seasoning metering container 131. The triggering structure 160 triggers the right opening and closing structure 150 at this time, but does not trigger the left opening and closing structure 150. Therefore, the left opening and closing structure 150 is still in the closed state, and the left seasoning metering container 131 is not connected to the third through hole 1321 on the left. Therefore, the seasoning stored in the left seasoning metering container 131 will not fall directly and automatically.

[0090] When it is necessary to output the seasoning from the left seasoning metering tank 131, the variable volume module 130 moves horizontally to the left. At this time, the left seasoning metering tank 131 gradually misaligns with the opening of the seasoning storage tank 120 until it is completely misaligned. The right seasoning metering tank 131 gradually aligns with the opening of the seasoning storage tank 120 until they are completely coaxial. The triggering structure 160 follows the horizontal leftward movement of the variable volume module 130, releasing the trigger on the right opening and closing structure 150, causing the right opening and closing structure 150 to gradually close. Then, it gradually triggers the left opening and closing structure 150, causing the left opening and closing structure 150 to gradually open. When the left seasoning metering tank 131 aligns with the left third through hole 1321... When fully aligned, the left opening structure 150 is opened to its maximum state. At this time, the left seasoning metering tank 131, the left third through hole 1321, and the left opening structure 150 are connected in pairs, so that all the seasonings originally stored in the left seasoning metering tank 131 are output to the seasoning dissolving tank 220. The right seasoning metering tank 131 is fully aligned with the seasoning storage tank 120, so that the seasonings stored in the right seasoning metering tank 131 can be realized. Since the triggering structure 160 triggers the left opening structure 150 at this time, the right opening structure 150 is in a fully closed state, and the right seasoning metering tank 131 and the right third through hole 1321 are misaligned.

[0091] When it is necessary to output the seasoning from the right-side seasoning metering tank 131, the variable volume module 130 moves horizontally to the right. At this time, the right-side seasoning metering tank 131 gradually misaligns with the opening of the seasoning storage tank 120 until it is completely misaligned. The left-side seasoning metering tank 131 gradually aligns with the opening of the seasoning storage tank 120 until they are completely coaxial. The triggering structure 160 follows the horizontal movement of the variable volume module 130 to the right, releasing the trigger on the left-side opening and closing structure 150, causing the left-side opening and closing structure 150 to gradually close. Then, it gradually triggers the right-side opening and closing structure 150, causing the right-side opening and closing structure 150 to gradually open. When the right-side seasoning metering tank 131 aligns with the right-side third through hole 132... When aligned, the right opening and closing structure 150 is opened to its maximum state. At this time, the right seasoning metering tank 131, the right third through hole 1321, and the right opening and closing structure 150 are connected in pairs, so that all the seasonings originally stored in the right seasoning metering tank 131 are output to the seasoning dissolving tank 220. Meanwhile, the left seasoning metering tank 131 is completely aligned with the seasoning storage tank 120, so that the seasonings stored in the left seasoning metering tank 131 can be realized. Since the triggering structure 160 triggers the right opening and closing structure 150 at this time, the left opening and closing structure 150 is in a completely closed state, and the left seasoning metering tank 131 and the left third through hole 1321 are misaligned.

[0092] Therefore, by unidirectional movement of the variable volume module 130, one of the seasoning metering containers 131 is connected to its third through-hole 1321 in the same direction, and the corresponding opening and closing structure 150 opens, discharging the seasoning pre-stored in the seasoning metering container 131. Meanwhile, the other seasoning metering container 131 is connected to the seasoning storage container 120, enabling the pre-storage of seasoning in the other container, while the opening and closing structure 150 in the same direction as the other container remains closed. Through the reciprocating movement of the variable volume module 130, the seasoning can be discharging twice, thereby improving the discharging efficiency.

[0093] More preferably, the opening and closing structure 150 includes:

[0094] The trigger plate 151 is located below the lifting bracket 132, and the first end of the trigger plate 151 is rotatably connected to the lifting bracket 132.

[0095] The guide frame 152 is connected at one end to the lifting bracket 132 and communicates with the third through hole 1321;

[0096] The first opening and closing plate 153 and the second opening and closing plate 154 are arranged opposite to each other and are rotatably connected to the other end of the guide frame 152. When no external force is applied, the first opening and closing plate 153 and the second opening and closing plate 154 each swing down under the action of gravity, so that one end of the first opening and closing plate 153 and the second opening and closing plate 154 are in contact, thereby closing the opening and closing structure 150.

[0097] The first link 155 and the second link 156 are connected, with the first end of the first link 155 rotatably connected to the first opening and closing plate 153, the second end of the first link 155 rotatably connected to the second end of the trigger plate 151, the first end of the second link 156 rotatably connected to the second opening and closing plate 154, and the second end of the second link 156 rotatably connected to the second end of the trigger plate 151.

[0098] It is worth mentioning that the rotational position of the first opening and closing plate 153 and the guide frame 152 coincides with the rotational position of the second opening and closing plate 154 and the guide frame 152; the rotational position of the first connecting rod 155 and the trigger plate 151 coincides with the rotational position of the second connecting rod 156 and the trigger plate 151.

[0099] Furthermore, the trigger structure 160 can move synchronously with the variable volume module 130. When the trigger structure 160 moves from the first end to the second end of the trigger plate 151, the trigger structure 160 gradually comes into contact with the trigger plate 151. As the trigger structure 160 moves, it squeezes the trigger plate 151, causing the trigger plate 151 to rotate around the first end. The second end of the trigger plate 151 gradually approaches the lifting bracket 132. Since the second end of the trigger plate 151 is connected to the first connecting rod 155 and the second connecting rod 156, as the trigger plate 151 approaches the lifting bracket 132... When the bracket 132 is in operation, the first connecting rod 155 and the second connecting rod 156 will be lifted. The first connecting rod 155 and the second connecting rod 156 are respectively connected to the first opening and closing plate 153 and the second opening and closing plate 154. Thus, the first opening and closing plate 153 and the second opening and closing plate 154 are lifted by the first connecting rod 155 and the second connecting rod 156 respectively. Since the first opening and closing plate 153 and the second opening and closing plate 154 are rotatably connected to the guide frame 152, the first opening and closing plate 153 and the second opening and closing plate 154 rotate during the lifting process, causing the opening and closing structure 150 to open. When the trigger structure 160 moves from the second end to the first end of the trigger plate 151, the trigger structure 160 gradually releases the pressure on the trigger plate 151, allowing the trigger plate 151 to fall freely in a direction away from the lifting bracket 132. Based on the self-weight of the first opening and closing plate 153 and the second opening and closing plate 154, the opening and closing structure 150 is closed by the rotation between the first opening and closing plate 153 and the second opening and closing plate 154 and the guide frame 152, respectively.

[0100] More preferably, in order to make the two opening and closing structures 150 more compactly installed on the lifting bracket 132, the trigger plates 151 in the two opening and closing structures 150 are arranged in an interlocking distribution, with the pressing position of the trigger structure 160 on one of the trigger plates 151 located in the middle region of the trigger plate 151; and the pressing position of the trigger structure 160 on the other trigger plate 151 located in the two side regions of the trigger plate 151.

[0101] More preferably, the triggering structure 160 includes two oppositely arranged trigger rods 161, and each trigger rod 161 is connected to the lower base 134 through a movable support plate 162, wherein a clearance groove 1324 is provided on the lifting bracket 132 to avoid the movement of the movable support plate 162.

[0102] The rice mixing module 40 includes a gyratory mixer, which comprises a frame 5100, a mixing cylinder 5200, and a support frame 5300. The mixing cylinder 5200 is cylindrical and has a mixing chamber 5201 extending through both ends. Each mixing chamber 5201 has an opening at both ends, which are sealed by a removable cover 5202. The cover 5202 can be quickly opened and closed, thereby achieving efficient material loading and unloading.

[0103] The mixing drum 5200 is rotatably mounted on the frame 5100, while the support frame 5300 is rotatably connected to the frame 5100 via a rotating shaft. A swing drive (e.g., a hydraulic cylinder, pneumatic cylinder, or electric push rod) is provided between the support frame 5300 and the frame 5100. This swing drive can drive the support frame 5300 to swing back and forth relative to the frame 5100, thereby causing the entire mixing drum 5200 to swing along its own axis. Simultaneously, the mixing drum 5200 can also be driven by an independent rotary drive device to rotate continuously around its own axis.

[0104] In actual use, the oscillating drive causes the mixing drum 5200 to oscillate periodically while rotating. This combined motion significantly enhances the tumbling, convection, and diffusion effects of the material within the mixing chamber 5201, improving mixing uniformity and efficiency. After mixing is complete, the equipment can be stopped, and the material can be quickly unloaded by opening the cover 5202 at either end.

[0105] Furthermore, two sets of abutment portions are rotatably mounted on the frame 5100, each set including at least two abutment wheels 5101. The two sets of abutment portions are respectively arranged at both ends of the mixing cylinder 5200 and roll in contact with the outer circumferential surface of the mixing cylinder 5200. Each abutment wheel 5101 is mounted in a support seat on the frame 5100 via bearings, its own axis being parallel to the axis of the mixing cylinder 5200, thereby providing stable support during the rotation and oscillation of the mixing cylinder 5200. This effectively limits the radial runout of the mixing cylinder 5200 while allowing it to rotate smoothly around its own axis.

[0106] Based on the aforementioned structure, abutment rings 5203 are fixedly provided at both ends of the outer surface of the mixing cylinder 5200. The abutment rings 5203 extend outward along the radial direction of the mixing cylinder, forming a flange structure surrounding the outer circumference of the mixing cylinder. Correspondingly, two sets of limiting parts are rotatably provided on the frame 5100. Each set of limiting parts includes at least two limiting wheels 5102, which are rotatably mounted on a bracket on the frame 5100 via bearings. The two sets of limiting parts are located at both ends of the mixing cylinder and roll in contact with the abutment rings 5203 at the corresponding ends. Specifically, the axis of the limiting wheel 5102 is perpendicular to the axis of the mixing cylinder, allowing the limiting wheel 5102 to roll along the side of the abutment ring 5203 (i.e., the end face of the abutment ring 5203 facing the axial direction of the mixing cylinder), thereby effectively constraining the axial movement of the mixing cylinder. This prevents the mixing cylinder 5200 from dislodging from its supported position due to inertia or gravity. Meanwhile, since the limit wheel 5102 can rotate freely, it always maintains rolling friction with the abutment ring 5203, which significantly reduces wear and running resistance.

[0107] Based on the aforementioned structure, a transmission rack 5204 is fixedly provided on the outer surface of the mixing cylinder 5200 along its radial direction. The transmission rack 5204 can be arranged in a ring around the outer periphery of the mixing cylinder. Preferably, it is integrated into the abutment ring 5203 at one end—that is, the outer edge of the abutment ring 5203 is machined into a gear-shaped structure, which serves as both an abutment ring 5203 for axial positioning and a transmission function, thus achieving a compact structure and functional integration.

[0108] Correspondingly, a drive unit 5103 (such as a geared motor, servo motor, etc.) is fixedly mounted on the frame 5100, and its output end is connected to a drive gear 5104. The drive gear 5104 meshes with the transmission rack 5204 on the mixing drum, forming an external meshing gear transmission pair. When the drive unit 5103 is started, the drive gear 5104 drives the transmission rack 5204, thereby driving the mixing drum to rotate around its own axis.

[0109] In this embodiment, a mounting bracket 5105 is hinged to the frame 5100, forming a flip-out connection with the frame 5100 for easy overall opening or closing. The cover 5202 is rotatably mounted on the mounting bracket 5105 via bearings or bushings, ensuring that the cover 5202 can be accurately aligned and cover the opening at the end of the mixing cylinder 5200.

[0110] When the cover 5202 closes to the opening position of the mixing cylinder 5200, the mounting bracket 5105 applies an axial clamping force to the end face of the mixing cylinder 5200 under the action of an external drive (such as a cylinder). Under the squeezing action of the mounting bracket 5105, the cover 5202 is pressed and sealed to the end face of the mixing cylinder 5200, and a reliable seal is achieved between the two through an annular sealing ring. Therefore, when the mixing cylinder 5200 rotates around its own axis under the drive of the drive gear 5104, the cover 5202 rotates synchronously with the mixing cylinder 5200 under the constraint of friction and squeezing force, while the mounting bracket 5105 itself remains stationary (or only serves as a swing support).

[0111] Based on the aforementioned structure, a tensioning part 5106 (e.g., a cylinder, hydraulic cylinder, or electric push rod) is hinged to the frame 5100. The cylinder body or housing of the tensioning part 5106 is rotatably connected to the frame 5100 via a pin, allowing it to adapt to changes in the movement trajectory of the cover 5202 during operation. The drive shaft (i.e., piston rod or push rod) of the tensioning part 5106 can perform linear extension and retraction along its axial direction, and its end is hinged to the cover 5202.

[0112] When it is necessary to close the end opening of the mixing drum 5200, the drive shaft of the tensioning part 5106 retracts (or extends, depending on the installation direction), pulling (or pushing) the cover 5202 to rotate around its pivot on the mounting bracket 5105, pressing the cover 5202 against the open end face of the mixing drum 5200, achieving a seal under the auxiliary pressing action of the mounting bracket 5105. At this time, as before, the cover 5202 can rotate freely relative to the mounting bracket 5105 in the pressed state and rotate synchronously with the mixing drum 5200.

[0113] In this embodiment, the support frame 5300 supports the mixing drum 5200. It is rotatably connected to the frame 5100 via a pivot, allowing the support frame 5300 to reciprocate relative to the frame 5100 about a horizontal pivot axis. To achieve this oscillation, a swinging part 5301 (e.g., a hydraulic cylinder, pneumatic cylinder, or electric push rod) is hinged to the support frame 5300. The cylinder body or housing of the swinging part 5301 is hinged to one side of the support frame 5300 via a pin, allowing it to adaptively adjust its angle as the support frame 5300 swings. The drive shaft (i.e., piston rod or push rod) of the swinging part 5301 can perform linear extension and retraction along its own axial direction, and its end is hinged to one end of the frame 5100 via a pin. When the drive shaft extends or retracts, it pushes or pulls the support frame 5300 to rotate about its connecting pivot to the frame 5100, thereby causing the entire mixing drum 5200 to reciprocate along its axial direction.

[0114] In this embodiment, the support frame 5300 is used to support the mixing cylinder 5200, and its overall structure includes two opposing and spaced-apart support portions 5302. These two support portions 5302 are arranged parallel to each other on the outer sides of both ends of the mixing cylinder 5200, together forming a stable support frame for the mixing cylinder 5200. The frame of each support portion 5302 has a triangular structure. This triangular frame has excellent geometric stability, preventing swaying or displacement.

[0115] To further enhance structural rigidity and load-bearing capacity, a reinforcing part 5303 is fixedly provided on the inner side of each support part 5302 (i.e., the side facing the other support part 5302). One end of the reinforcing part 5303 is firmly connected to the upper or middle part of the support part 5302, and the other end extends downward and is fixedly connected to the base frame 5304. The base frame 5304 is horizontally arranged at the bottom of the support frame 5300, and laterally connects the lower ends of the two support parts 5302 to form an integral chassis structure. Thus, the reinforcing part 5303, the side of the support part 5302, and a part of the base frame 5304 together constitute one or more auxiliary triangular structures.

[0116] In this embodiment, the mixing cylinder 5200 is a hollow cylindrical structure, with a mixing chamber 5201 inside for containing and mixing materials. To enhance the agitation, dispersion, and mixing effect of materials inside the cylinder, several stirring sections 5205 are fixedly arranged on the inner wall of the mixing cylinder 5200. Each stirring section 5205 includes several annularly spaced stirring plates. These stirring plates protrude from the inner wall of the mixing cylinder 5200 toward the center of the cavity and extend a certain length along the axial direction of the mixing cylinder 5200. The stirring plates are not arranged in a straight line along the axial direction, but are arranged in a spiral or oblique direction along the outer circumference (i.e., the circumferential direction) of the mixing cylinder 5200 during their extension, forming a structure similar to a "spiral guide vane" or "oblique blade". When the mixing drum 5200 rotates under the drive of the drive gear 5104, the mixing plate rotates together with the drum body. Its inclined surface will continuously apply axial thrust and circumferential shear force to the material, causing the material to not only roll around the circumference, but also move back and forth along the axial direction.
