[0044] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0045] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0046] like Figures 1 to 15 As shown, the present invention provides a steamed cake production line, comprising:

[0047] A first conveyor line 100 is provided with a plurality of workstations, namely a first workstation 110, a second workstation 120, a third workstation 130, a fourth workstation 140, a fifth workstation 150 and a sixth workstation 160. The first workstation 110 is provided with a first pre-processing mechanism 200 for outputting red kidney beans for the first time, the second workstation 120 is provided with a second pre-processing mechanism 300 for outputting glutinous rice for the first time, the third workstation 130 is used for laying jujube filling for the first time, the fourth workstation 140 is used for laying raisins for the first time, the fifth workstation 150 is used for laying jujube filling for the second time, and the sixth workstation 160 is used for laying jujube filling for the second time;

[0048] The second conveyor line 400 is aligned with the first conveyor line 100 and is provided with a seventh station 410. A third pre-processing mechanism 500 for outputting the red kidney beans for the second time is also provided at the seventh station 410. The output end of the third pre-processing mechanism 500 is located on the first conveyor line 100 and between the third station 130 and the fourth station 140.

[0049] The third conveyor line 600 is aligned with the first conveyor line 100 and is provided with an eighth station 610. A fourth pre-processing mechanism 700 for outputting glutinous rice for the second time is provided at the eighth station 610. The output end of the fourth pre-processing mechanism 700 is located on the first conveyor line 100 and between the fourth station 140 and the fifth station 150.

[0050] Among them, a first steaming mechanism 170 for synchronously pre-cooking the red kidney beans and glutinous rice output for the first time is provided between the second station 120 and the third station 130, a second steaming mechanism 420 for pre-cooking the red kidney beans output for the second time is provided between the seventh station 410 and the output end of the second conveyor line 400, a third steaming mechanism 620 for pre-cooking the glutinous rice output for the second time is provided between the eighth station 610 and the output end of the third conveyor line 600, and a fourth steaming mechanism 180 for steaming the steamed cake as a whole is provided between the sixth station 160 and the output end of the first conveyor line 100.

[0051] It is worth mentioning that no matter whether it is the first time or the second time the raisins and jujube fillings are laid, their content is relatively small compared to red kidney beans and glutinous rice, so they are laid manually without setting up additional equipment for separate laying. This shortens the floor space of the entire steamed cake production line on the one hand, and reduces the cost of steamed cakes on the other.

[0052] The present invention provides a steamed cake production line, which reduces the labor intensity of workers and realizes the automated production of steamed cakes by outputting ingredients with high demand in the steamed cakes in an automated manner and outputting ingredients with low demand in the steamed cakes in a manually spread manner. In addition, by providing a first steaming mechanism 170, a second steaming mechanism 420 and a third steaming mechanism 620, pre-steaming treatment is achieved for ingredients that require a long steaming time, ensuring that all ingredients in the steamed cakes finally output from the fourth steaming mechanism 180 are steamed synchronously, thereby ensuring the overall taste of the steamed cakes.

[0053] It is worth mentioning that in order to ensure that all ingredients in the steamed cake are steamed synchronously when finally output, the first steaming mechanism 170, the second steaming mechanism 420, the third steaming mechanism 620 and the fourth steaming mechanism 180 have differences in length. Among them, the lengths of the first steaming mechanism 170 and the third steaming mechanism 620 are the same, the length of the second steaming mechanism 420 is half the length of the first steaming mechanism 170 or the third steaming mechanism 620, and the length of the fourth steaming mechanism 180 is twice the length of the first steaming mechanism 170 or the third steaming mechanism 620.

[0054] The lengths of the various steaming mechanisms are different because the cooking times required for each ingredient in the steamed cake vary. For example, glutinous rice requires longer cooking time than red kidney beans, so the lengths of the first and third steaming mechanisms 170 and 620 are longer than those of the second steaming mechanism 420. Dates and raisins are easy-to-cook ingredients in the steamed cake, so they only need to be cooked through the fourth steaming mechanism 180.

[0055] Further preferably, in order to further reduce the distance in the length direction and the distance in the width direction of the steamed cake production line. Therefore, in this embodiment, the input end of the first pretreatment mechanism 200 on the first station 110 and the input end of the second pretreatment mechanism 300 on the second station 120 are respectively located on both sides of the first conveyor line 100, and the output end of the first pretreatment mechanism 200 on the first station 110 and the output end of the second pretreatment mechanism 300 on the second station 120 are both located on the first conveyor line 100. In addition, the second conveyor line 400 and the third conveyor line 600 are arranged parallel to each other and opposite to each other, wherein the second conveyor line 400 There is a height difference between the third conveyor line 600 and the first conveyor line 100, and an elevator 430 is provided between the second conveyor line 400 and the first conveyor line 100, and between the third conveyor line 600 and the first conveyor line 100. The red kidney beans and glutinous rice pre-cooked by the second steaming mechanism 420 and the third steaming mechanism 620 are respectively entered into the corresponding rice dispenser 190 on the first conveyor line 100 through the corresponding elevator 430, and the red kidney beans and glutinous rice are spread flat on the food box where the steamed cake is located through the rice dispenser 190.

[0056] It is worth mentioning that the reason for setting up the rice dispenser 190 on the first conveyor line 100 is to strictly control the weight of the ingredients on the corresponding layers in the food box to avoid too much or too little corresponding ingredients, so as to ensure the taste of the steamed cake after steaming.

[0057] Preferably, the first pretreatment mechanism 200 and the third pretreatment mechanism 500 have the same structure, both including a red kidney bean rice bin 210, a single-cylinder rice washing machine 220 and a red kidney bean filling machine 230 connected side by side in sequence; the second pretreatment mechanism 300 and the fourth pretreatment mechanism 700 have the same structure, both including a pouring table 310, an elevator 430, a glutinous rice bin 320, a spiral rice washing machine 330 and a glutinous rice filling machine 340 connected side by side in sequence, wherein the positions of the red kidney bean rice bin 210 and the pouring table 310 are used to screen impurities in red kidney beans and glutinous rice, thereby ensuring that there are no impurities in the steamed cake entering the final form, thereby improving the taste of the steamed cake.

[0058] It is worth mentioning that since the particle volume of red kidney beans is larger than that of glutinous rice, the screening of red kidney beans is faster than that of glutinous rice in the process of screening impurities. Therefore, when screening glutinous rice, it is necessary to first pour the glutinous rice onto the pouring table 310, and then the screened glutinous rice enters the glutinous rice bin 320 through the elevator 430, which provides corresponding buffer time for the screening of glutinous rice, making the screening of glutinous rice more sufficient.

[0059] Further preferably, the red kidney bean filling machine 230 has the same structure as the glutinous rice filling machine 340 . Therefore, the structure of the filling machine will be described by taking the structure of the red kidney bean filling machine 230 as an example.

[0060] Preferably, the single-cylinder rice washing machine 220 includes a single-cylinder bracket 221, and two upper and lower cavities are formed on the single-cylinder bracket 221, namely a single-cylinder upper cavity 2211 and a single-cylinder lower cavity 2212, wherein the single-cylinder upper cavity 2211 is used for storing water, and the single-cylinder lower cavity 2212 is used as a driving structure; a single-cylinder material receiving barrel 222 passes through the single-cylinder upper cavity 2211 and the single-cylinder lower cavity 2212, and is fixed on the partition plate between the single-cylinder upper cavity 2211 and the single-cylinder lower cavity 2212, wherein the end of the single-cylinder material receiving barrel 222 located in the single-cylinder upper cavity 2211 is a red The feeding end of the kidney beans is arranged in a columnar shape, and one end of the single-cylinder receiving barrel 222 located in the single-cylinder lower cavity 2212 is the discharge end of the red kidney beans, and is arranged in a conical shape; the driving structure includes a water pump 223 installed in the single-cylinder lower cavity 2212, and the water inlet end of the water pump 223 extends into the single-cylinder upper cavity 2211 through the water inlet pipe 224, and the water outlet end of the water pump 223 is connected to the three-way valve 226 connected to the discharge end of the single-cylinder receiving barrel 222 through the water outlet pipe 225; the single-cylinder discharge pipe 227, one end is connected to the three-way valve 226, and the other end is connected to the red kidney bean filling machine 230.

[0061] It is worth mentioning that the feed end on the single-cylinder receiving barrel 222 is used to receive the red kidney beans delivered from the red kidney bean rice bin 210. The red kidney beans are dry red kidney beans. They pass through the single-cylinder receiving barrel 222 and enter the three-way valve 226 from the discharge end of the single-cylinder receiving barrel 222. Then the water pump 223 works to absorb the water in the single-cylinder upper cavity 2211. Through the water inlet pipe 224 and the water outlet pipe 225 of the water pump 223, it meets the dry red kidney beans in the three-way valve 226. The dust on the surface of the red kidney beans is washed away by the impact of the water flow, thereby achieving the purpose of cleaning. During the cleaning process, the red kidney beans pass through the single-cylinder discharge pipe 227 and enter the red kidney bean filling machine 230 for soaking treatment, so as to soften the red kidney beans.

[0062] In addition, the feed end of the single-cylinder discharge pipe 227 is connected to the three-way valve 226 and is arranged horizontally, and the discharge end of the single-cylinder discharge pipe 227 is arranged vertically, so that the red kidney beans output from the single-cylinder discharge pipe 227 can enter the red kidney bean filling machine 230 from top to bottom.

[0063] Further preferably, a single-cylinder circulation pipe 2271 is provided on the single-cylinder discharge pipe 227, and the discharge end of the single-cylinder circulation pipe 2271 is aligned with the single-cylinder receiving barrel 222, wherein a three-way switch valve 2272 is provided at the intersection of the single-cylinder circulation pipe 2271 and the single-cylinder discharge pipe 227 for selectively connecting the single-cylinder circulation pipe 2271 or the single-cylinder discharge pipe 227.

[0064] It is worth mentioning that when the single-cylinder circulation pipe 2271 is connected through the three-way switch valve 2272 and the discharge end of the single-cylinder discharge pipe 227 is blocked, the single-cylinder receiving barrel 222, the water inlet pipe 224 of the water pump 223, the water pump 223, the water outlet pipe 225 of the water pump 223, the three-way valve 226, the single-cylinder discharge pipe 227, and the single-cylinder circulation pipe 2271 form a circulating water path for washing the red kidney beans, thereby further improving the washing effect of the red kidney beans. After washing is completed, the single-cylinder circulation pipe 2271 is blocked through the three-way switch valve 2272 and the three-way switch valve 2272 is connected to the discharge end of the single-cylinder discharge pipe 227, so that the washed red kidney beans are fed into the red kidney bean filling machine 230.

[0065] Further preferably, the plane where the feeding end of the single-cylinder receiving barrel 222 is located is higher than the horizontal plane in the single-cylinder upper cavity 2211, and the plane where one end of the water inlet pipe 224 of the water pump 223 is located in the single-cylinder upper cavity 2211 is lower than the horizontal plane in the single-cylinder upper cavity 2211, wherein a single-cylinder overflow pipe 228 is also provided in the single-cylinder upper cavity 2211, and the single-cylinder overflow pipe 228 passes through the partition plate, and the plane where one end of the single-cylinder overflow pipe 228 is located in the single-cylinder upper cavity 2211 is higher than the horizontal plane in the single-cylinder upper cavity 2211 and lower than the plane where the feeding end of the single-cylinder receiving barrel 222 is located.

[0066] In this embodiment, the plane where the feeding end of the single-cylinder receiving barrel 222 is located is higher than the horizontal plane in the single-cylinder upper cavity 2211, so that the single-cylinder receiving barrel 222 can receive all the red kidney beans delivered from the red kidney bean rice bin 210 and will not directly enter the single-cylinder upper cavity 2211, thereby preventing the red kidney beans from being suspended or deposited at the bottom of the single-cylinder upper cavity 2211 and unable to enter the single-cylinder receiving barrel 222, resulting in waste of red kidney beans; one end of the water inlet pipe 224 of the water pump 223 is lower than the horizontal plane of the single-cylinder upper cavity 2211, This is to ensure that when the water pump 223 is started, there needs to be a certain amount of water in the water pump 223 to achieve the normal operation of the water pump 223; the plane where the single-cylinder overflow pipe 228 is located is higher than the horizontal plane in the single-cylinder upper cavity 2211, in order to control the water storage capacity in the single-cylinder upper cavity 2211.

[0071] Further preferably, the spiral cleaning structure 332 includes a spiral groove 3321 installed in the spiral upper cavity 3311, which is arranged in a U-shaped structure, and a spiral shaft 3322 is installed in the spiral groove 3321, wherein one end of the spiral shaft 3322 is connected to the motor 3323, and the other end of the spiral shaft 3322 is installed on the spiral groove 3321 through a bearing seat, and the closed end of the spiral groove 3321 faces the bottom of the spiral upper cavity 3311, and the open end of the spiral groove 3321 is provided with a sealing plate, which is provided with a through hole 3327 connected to the glutinous rice bin 320; a spray pipe 3324, one end of which extends out of the spiral groove 3321, and the other end is connected to the municipal waterway, wherein the spray port on the spray pipe 3324 is aligned with the spiral groove 3321.

[0072] In this embodiment, a spiral cleaning structure 332 is provided so that the glutinous rice in the spiral groove 3321 is wetted by the water sprayed from the spray pipe 3324, and then rolls forward under the rotation of the spiral shaft 3322, so that the glutinous rice entering the spiral receiving barrel 333 is soaked, thereby achieving pretreatment for the subsequent cleaning of the glutinous rice.

[0073] Further preferably, the sealing plate located at the open end of the spiral groove 3321 includes a first sealing cover 3325 and a second sealing cover 3326 , and the through hole 3327 is provided on the first sealing cover 3325 .

[0074] Preferably, the red kidney bean filling machine 230 includes a soaking barrel 231, and one end of the soaking barrel 231 is connected to the single-cylinder rice washing machine 220, and the other end of the soaking barrel 231 is connected to the discharge barrel 232, wherein the soaking barrel 231 and the discharge barrel 232 are connected through a threaded ball valve 233; the discharge structure 234 is located below the discharge barrel 232, and the discharge structure 234 includes a discharge bracket 2341, and a discharge cylinder is installed on the discharge bracket 2341. 2342, wherein the output end of the discharging cylinder 2342 is connected to a receiving plate 2343, one side of the receiving plate 2343 is in abutment with the discharging barrel 232, and a discharging frame 2344 is provided on the other side of the receiving plate 2343, and a discharging hole 2345 connected with the discharging frame 2344 is provided on the receiving plate 2343; the conveying track 235 is located below the discharging frame 2344, and the food box used to carry the steamed cake is conveyed forward through the conveying track 235.

[0075] It is worth mentioning that when the red kidney beans in the soaking barrel 231 enter the discharge barrel 232, the discharge barrel 232 and the closed area on the receiving plate 2343 (the area where the discharge hole 2345 is not set) form abutment. When the volume of the red kidney beans in the discharge barrel 232 reaches the preset volume, the discharge cylinder 2342 pulls the receiving plate 2343 so that the discharge hole 2345 on the receiving plate 2343 is aligned with the discharge barrel 232, so that the red kidney beans in the discharge barrel 232 pass through the discharge hole 2345 and the discharge frame 2344 into the food box on the conveying track 235. Since the movement of the receiving plate 2343 is a horizontal movement, the connecting channel between the discharge hole 2345 and the discharge barrel 232 is gradually opened, so that the red kidney beans output from the discharge hole 2345 can be spread flat on the food box, ensuring the reliability of the flat spreading of the red kidney beans.

[0076] Further preferably, the discharge bracket 2341 is used as a reference, and two water collecting frames are provided on the upper and lower sides of the discharge bracket 2341, namely the first water collecting frame 2346 and the second water collecting frame 2347, wherein the first water collecting frame 2346 surrounds the periphery of the discharge barrel 232, the second water collecting frame 2347 is staggered with the first water collecting frame 2346, and the first water collecting frame 2346 and the second water collecting frame 2347 are connected by a pipe 2348.

[0077] It is worth mentioning that the red kidney beans flowing from the soaking barrel 231 into the discharge barrel 232 are mixed with water, but only red kidney beans are needed for steamed cakes. Therefore, the discharge barrel 232 is set to be mesh-shaped, so that the mixture (red kidney beans and water) entering the discharge barrel 232, the water body enters the first water collecting frame 2346 through the mesh on the discharge barrel 232. If the second water collecting frame 2347 is not set, the water body drained from the discharge barrel 232 will return to the discharge barrel 232. Therefore, by setting the second water collecting frame 2347, and the second water collecting frame 2347 is connected to the first water collecting frame 2346 through the pipe 2348, the water body drained from the discharge barrel 232 can quickly enter the second water collecting frame 2347 through the pipe 2348 after entering the first water collecting frame 2346, thereby ensuring that the discharge barrel 232 contains only red kidney beans, but no water. In order to avoid excessive water accumulation in the second water collecting frame 2347, a water outlet can be provided at the bottom of the second water collecting frame 2347 to discharge the water from the second water collecting frame 2347 in a timely manner through the water outlet.
