Description

Technical Field

[0001] This invention relates to the field of rice and flour product cooking technology, specifically to a track-type preheating device and process for continuous cooking of rice and flour products. Background Technology

[0002] Rice and noodle products generally refer to foods made primarily from rice flour or rice noodles. These products are typically rich in carbohydrates and contain a small amount of protein, making them suitable as a staple food. Common rice and noodle products include rice noodles, rice vermicelli, and rice rice noodles, which can be used to make a variety of delicious rice noodle dishes.

[0003] Rice and flour products require steaming during production and processing. Traditionally, steaming of rice and flour products is mostly done using a single-furnace steam heating method, where the rice and flour products are directly placed in the steamer for heating. This method is inconvenient for preheating the rice and flour products and results in uneven heating, affecting the taste and processing quality of the products. To address these issues, we propose a track-type preheating equipment and process for continuous steaming of rice and flour products. Summary of the Invention

[0004] The purpose of this invention is to provide a track-type preheating device and process for continuous steaming of rice and flour products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a track-type preheating device for continuous steaming of rice and flour products, comprising a support frame, a transmission mechanism fixedly installed at the top of the support frame, a steaming outer frame fixedly installed at the top of the transmission mechanism, an auxiliary mechanism fixedly installed at the bottom of the support frame, a collection hopper frame fixedly installed at the bottom of the auxiliary mechanism, a waste discharge pipe fixedly installed at the bottom of the collection hopper frame, and a cleaning mechanism fixedly installed on the side of the auxiliary mechanism away from the steaming outer frame, the cleaning mechanism being located below the transmission mechanism.

[0006] As a preferred embodiment of the present invention, the transmission mechanism includes two symmetrically distributed transmission side frames, which are fixedly installed on the top of the support frame. A plurality of transmission rollers are rotatably installed between the transmission side frames, and a transmission belt is movably sleeved on the outer side of the plurality of transmission rollers.

[0007] As a preferred embodiment of the present invention, the cooking outer frame is fixedly installed on the top of the transmission side frame, a first heat preservation plate is fixedly provided in the cooking outer frame, and a plurality of evenly distributed partitions are fixedly installed on the inner side of the cooking outer frame, the plurality of partitions dividing the cooking outer frame into a plurality of cooking chambers, and a steam spray frame is fixedly installed in each cooking chamber.

[0008] As a preferred embodiment of the present invention, the auxiliary mechanism includes an auxiliary bottom frame, which is fixedly installed at the bottom end of the transmission side frame. The collection hopper frame is fixedly installed at the bottom end of the auxiliary bottom frame. The length of the auxiliary bottom frame is greater than the length of the cooking outer frame. A second insulation plate is fixedly installed in the auxiliary bottom frame. Waste discharge slots are provided at both ends of the inner side of the auxiliary bottom frame and at both ends of the second insulation plate. A scraper is slidably engaged at the bottom inner side of the auxiliary bottom frame. The bottom end of the scraper contacts the lower inner wall of the auxiliary bottom frame, and the side wall of the scraper contacts the inner side wall of the auxiliary bottom frame. Drive blocks are fixedly installed on both sides of the top end of the scraper.

[0009] As a preferred embodiment of the present invention, the auxiliary mechanism further includes two sets of auxiliary shafts symmetrically distributed. The auxiliary shafts are rotatably mounted on the inner ends of the auxiliary base frame. A first sprocket is fixedly mounted on the opposite ends of the auxiliary shafts. A first chain is meshed with the outer sides of the two first sprockets on the same side. A drive shaft is fixedly mounted on the first chain. A drive groove corresponding to the drive shaft is opened on the drive block. The drive shaft is movably engaged in the corresponding drive groove.

[0010] As a preferred embodiment of the present invention, a second sprocket is fixedly mounted on the outer side of one of the auxiliary shafts, a third sprocket is fixedly mounted on the end of the transmission roller at the position of the second sprocket, and a second chain is vertically meshed with the outer sides of the second sprocket and the third sprocket.

[0011] As a preferred embodiment of the present invention, the cleaning mechanism includes a plurality of uniformly distributed liquid guiding frames, a connecting pipe fixedly installed between the plurality of liquid guiding frames, the plurality of liquid guiding frames and the connecting pipes communicating with each other, a liquid guiding main pipe fixedly installed at the end of the connecting pipe, the liquid guiding main pipe fixedly installed on the side of the auxiliary bottom frame away from the cooking outer frame, a cleaning brush fixedly installed at the top of each liquid guiding frame, the cleaning brush contacting the lower surface of the conveyor belt, and a plurality of uniformly distributed spray holes opened at the top of the liquid guiding frame.

[0012] As a preferred embodiment of the present invention, an observation groove is provided on the top of one side of the cooking frame, and an observation window is fixedly installed in the observation groove.

[0013] As a preferred embodiment of the present invention, a first motor is fixedly installed on one side of one of the transmission side frames, and the drive end of the first motor is fixedly installed on one end of the corresponding transmission roller.

[0014] A process for a track-type preheating device for continuous steaming of rice and flour products includes the following steps:

[0015] Step 1: Connect the end of the liquid guide pipe to the output port of the cleaning water output system, control the first motor to drive the corresponding transmission roller to rotate, thereby driving the transmission belt to transport. While the transmission roller rotates, in conjunction with the transmission of the second sprocket, the third sprocket and the second chain, control one of the auxiliary shafts to rotate, drive the first sprocket to rotate and drive the first chain to transport, thereby driving the drive shaft to transport. Since the drive shaft is movably engaged in the corresponding drive longitudinal groove, the drive shaft transmission control drive block moves back and forth in the auxiliary bottom frame.

[0016] Step 2: Place the rice and flour products to be steamed on the conveyor belt. As the conveyor belt moves, the rice and flour products are transported in a track-like manner. Multiple partitions divide the outer frame of the steaming container into multiple steaming chambers. Each steaming chamber is equipped with a steam spray frame. Control the external steam generator to input steam into the steam spray frame, so that steam at different temperatures is delivered to each steaming chamber through multiple steam spray frames. This allows the rice and flour products transported on the conveyor belt to be continuously preheated and steamed at different temperatures, so that the rice and flour products are heated evenly. The staff can observe the steaming and processing effect of the rice and flour products in the outer frame of the steaming container through the observation window.

[0017] The first insulation board is made of high-density foam board to keep the temperature of the outer frame of the steaming and cooking process, and the second insulation board is made of high-density foam board to keep the temperature of the auxiliary bottom frame, thereby improving the steaming and cooking effect of rice and flour products.

[0018] The condensate generated during cooking falls into the auxiliary bottom frame for collection. The control turns on the cleaning water output system. The cleaning water is introduced into the connecting pipe through the output port and the liquid guide main pipe, and then into multiple liquid guide frames. It is then evenly sprayed onto the lower surface of the conveyor belt through multiple spray holes. With the automatic transmission of the conveyor belt and the contact between the cleaning brush and the lower surface of the conveyor belt, the cleaning brush automatically cleans the lower surface of the conveyor belt with the cleaning water. The wastewater generated during cleaning falls into the auxiliary bottom frame for collection.

[0019] By controlling the drive block to reciprocate within the auxiliary bottom frame, the scraper is driven to reciprocate within the auxiliary bottom frame. Since the bottom end of the scraper contacts the lower inner wall of the auxiliary bottom frame, and the side wall of the scraper contacts the inner side wall of the auxiliary bottom frame, the scraper cleans the impurities attached to the inner wall of the auxiliary bottom frame. At the same time, it pushes the cleaned impurities, condensate, and wastewater through the waste discharge channel to the collection hopper frame, and then discharges them through the waste discharge pipe, thereby automatically cleaning the collected condensate, wastewater, and impurities.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. By setting up a transmission mechanism and using a cooking frame with multiple partitions and steam spray frames, rice and flour products are transported by track, which enables continuous preheating and cooking of the transported rice and flour products at different temperatures. Compared with the traditional single-furnace steam heating method, this equipment can make multiple rice and flour products heat evenly, improve the taste and processing quality of rice and flour products, and increase the cooking efficiency of rice and flour products.

[0022] 2. By setting up a cleaning mechanism, the lower surface of the conveyor belt is automatically cleaned to prevent residual rice and flour product impurities from adhering to the conveyor belt surface from affecting the clean placement and steaming of subsequent rice and flour products, thereby further improving the overall performance of the rice and flour product preheating equipment.

[0023] 3. By setting up an auxiliary mechanism, condensate and wastewater are collected, and by driving the scraper to move back and forth in the auxiliary bottom frame, the impurities attached to the inner wall of the auxiliary bottom frame are cleaned. At the same time, the cleaned impurities, condensate and wastewater are automatically discharged through the waste discharge channel, thereby automatically cleaning the collected condensate, wastewater and impurities, improving the overall performance of the rice and flour product preheating equipment.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example: Figure 1-11 As shown, the present invention provides a track-type preheating device for continuous steaming of rice and flour products, including a support frame 1. A transmission mechanism 2 is fixedly installed at the top of the support frame 1, and a steaming outer frame 3 is fixedly installed at the top of the transmission mechanism 2. An auxiliary mechanism 4 is fixedly installed at the bottom of the support frame 1, and a collection hopper frame 5 is fixedly installed at the bottom of the auxiliary mechanism 4. A waste discharge pipe 51 is fixedly installed at the bottom of the collection hopper frame 5. A cleaning mechanism 6 is fixedly installed on the side of the auxiliary mechanism 4 away from the steaming outer frame 3, and the cleaning mechanism 6 is located below the transmission mechanism 2.

[0039] The transmission mechanism 2 includes two symmetrically distributed transmission side frames 21, which are fixedly installed on the top of the support frame 1. A plurality of evenly distributed transmission rollers 22 are rotatably installed between the transmission side frames 21, and a transmission belt 23 is movably sleeved on the outer side of the plurality of transmission rollers 22. A first motor 24 is fixedly installed on one side of one of the transmission side frames 21. The drive end of the first motor 24 is fixedly installed on one end of the corresponding transmission roller 22. In use, the first motor 24 is turned on to drive the corresponding transmission roller 22 to rotate, thereby driving the transmission belt 23 to transport the rice and flour products to be steamed. The rice and flour products are placed on the transmission belt 23. With the transmission of the transmission belt 23, the rice and flour products are transported in a track-like manner, which facilitates the continuous steaming and cooking of multiple rice and flour products.

[0040] The outer frame 3 is fixedly installed on the top of the transmission side frame 21. A first insulation board 32 is fixedly installed in the outer frame 3. The first insulation board 32 is made of high-density foam board to keep the temperature in the outer frame 3. An observation groove is opened on the top of one side of the outer frame 3. An observation window 33 is fixedly installed in the observation groove. By setting the observation window 33, it is convenient for staff to observe the steaming and processing effect of rice and flour products in the outer frame 3.

[0041] Multiple evenly distributed partitions 34 are fixedly installed on the inner side of the cooking frame 3, dividing the cooking frame 3 into multiple cooking chambers. Each cooking chamber is equipped with a steam spray frame 35. By setting multiple partitions 34, the cooking frame 3 is divided into multiple cooking chambers, and each cooking chamber is equipped with a steam spray frame 35. Steam is input into the steam spray frame 35 by controlling an external steam generator, so that steam at different temperatures is delivered to each cooking chamber through multiple steam spray frames 35. This allows for continuous preheating and cooking of rice and flour products conveyed on the conveyor belt 23 at different temperatures, ensuring that the rice and flour products are heated evenly, improving the taste and processing quality of the rice and flour products, and increasing the cooking efficiency of the rice and flour products.

[0042] The auxiliary mechanism 4 includes an auxiliary bottom frame 41, which is fixedly installed at the bottom end of the transmission side frame 21. A collection hopper frame 5 is fixedly installed at the bottom end of the auxiliary bottom frame 41. The length of the auxiliary bottom frame 41 is greater than the length of the outer steaming frame 3. Condensate generated during steaming falls into the auxiliary bottom frame 41 and is collected. A second insulation board 42, made of high-density foam board, is fixedly installed in the auxiliary bottom frame 41 to maintain the temperature within the frame, thereby improving the steaming effect of rice and flour products. Waste discharge channels 401 are provided at both ends of the inner side of the auxiliary bottom frame 41 and at both ends of the second insulation board 42. These channels facilitate the subsequent discharge of condensate and wastewater collected in the auxiliary bottom frame 41. A scraper 43 is slidably mounted on the inner bottom of the auxiliary bottom frame 41. The bottom end of the scraper 43 contacts the lower inner wall of the auxiliary bottom frame 41, and the side wall of the scraper 43 contacts the inner side wall of the auxiliary bottom frame 41. A drive block 44 is fixedly installed on both sides of the top of the scraper 43. By controlling the drive block 44 to move back and forth in the auxiliary bottom frame 41, the scraper 43 is driven to move back and forth in the auxiliary bottom frame 41. Since the bottom end of the scraper 43 contacts the lower inner wall of the auxiliary bottom frame 41, and the side wall of the scraper 43 contacts the inner side wall of the auxiliary bottom frame 41, the scraper 43 cleans the impurities attached to the inner wall of the auxiliary bottom frame 41. At the same time, it pushes the cleaned impurities, condensate, and wastewater to be automatically discharged through the waste discharge channel 401, thereby automatically cleaning the collected condensate, wastewater, and impurities, and improving the overall performance of the rice and flour product preheating equipment.

[0043] The auxiliary mechanism 4 also includes two sets of symmetrically distributed auxiliary shafts 45. The auxiliary shafts 45 are rotatably mounted on the inner ends of the auxiliary base frame 41. A first sprocket 451 is fixedly mounted on the opposite ends of the auxiliary shafts 45. A first chain 452 is meshed with the outer sides of the two first sprockets 451 on the same side. A drive shaft 453 is fixedly mounted on the first chain 452. A drive groove 441 corresponding to the drive shaft 453 is opened on the drive block 44. The drive shaft 453 is movably engaged in the corresponding drive groove 441. In use, by controlling one of the auxiliary shafts 45 to rotate, the first sprocket 451 is driven to rotate, driving the first chain 452 to transmit, thereby driving the drive shaft 453 to transmit. Since the drive shaft 453 is movably engaged in the corresponding drive groove 441, the drive shaft 453 transmits and controls the drive block 44 to reciprocate within the auxiliary base frame 41.

[0044] A second sprocket 46 is fixedly mounted on the outer side of one of the auxiliary shafts 45. A third sprocket 461 is fixedly mounted on the end of the transmission roller 22 at the position of the second sprocket 46. A second chain 462 is vertically meshed with the outer sides of the second sprocket 46 and the third sprocket 461. When the transmission roller 22 rotates, it cooperates with the transmission of the second sprocket 46, the third sprocket 461 and the second chain 462 to control the rotation of one of the auxiliary shafts 45.

[0045] The cleaning mechanism 6 includes a plurality of evenly distributed liquid guiding frames 61, with connecting pipes 62 fixedly installed between the plurality of liquid guiding frames 61. The plurality of liquid guiding frames 61 and the connecting pipes 62 are interconnected. A liquid guiding main pipe 63 is fixedly installed at the end of the connecting pipe 62. The liquid guiding main pipe 63 is fixedly installed on the side of the auxiliary bottom frame 41 away from the cooking outer frame 3. A cleaning brush 64 is fixedly installed at the top of each liquid guiding frame 61. The cleaning brush 64 contacts the lower surface of the conveyor belt 23. A plurality of evenly distributed spray holes 601 are opened at the top of the liquid guiding frame 61. In use, the end of the liquid guiding main pipe 63 and the cleaning water are connected. The system output port is connected to control the start of the cleaning water output system. The cleaning water is introduced into the connecting pipe 62 through the output port and the liquid guide main pipe 63, and then into multiple liquid guide frames 61. It is then evenly sprayed onto the lower surface of the conveyor belt 23 through multiple spray holes 601. With the automatic transmission of the conveyor belt 23 and the contact between the cleaning brush 64 and the lower surface of the conveyor belt 23, the cleaning brush 64 automatically cleans the lower surface of the conveyor belt 23 with the cleaning water, preventing the remaining rice and flour product impurities on the surface of the conveyor belt 23 from affecting the clean placement and cooking of the rice and flour products in the subsequent processing, and further improving the overall performance of the rice and flour product preheating equipment.

[0046] A process for a track-type preheating device for continuous steaming of rice and flour products includes the following steps:

[0047] Step 1: Connect the end of the liquid guide pipe 63 to the output port of the cleaning water output system, and control the first motor 24 to drive the corresponding transmission roller 22 to rotate, thereby driving the transmission belt 23 to carry out transmission. While the transmission roller 22 rotates, in conjunction with the transmission of the second sprocket 46, the third sprocket 461 and the second chain 462, control one of the auxiliary shafts 45 to rotate, drive the first sprocket 451 to rotate and drive the first chain 452 to carry out transmission, thereby driving the drive shaft 453 to carry out transmission. Since the drive shaft 453 is movably engaged in the corresponding drive longitudinal groove 441, the drive shaft 453 transmission control drive block 44 reciprocates in the auxiliary bottom frame 41.

[0048] Step 2: Place the rice and flour products to be steamed on the conveyor belt 23. As the conveyor belt 23 moves, the rice and flour products are transported in a track-like manner. Multiple partitions 34 divide the outer frame 3 of the steaming into multiple steaming chambers. Each steaming chamber is equipped with a steam spray frame 35. Control the external steam generator to input steam into the steam spray frame 35, so that steam at different temperatures is delivered to each steaming chamber through multiple steam spray frames 35. This allows the rice and flour products transported on the conveyor belt 23 to be continuously preheated and steamed at different temperatures, so that the multiple rice and flour products are heated evenly. The staff can observe the steaming and processing effect of the rice and flour products in the outer frame 3 through the observation window 33.

[0049] The first insulation board 32 is made of high-density foam board to keep the temperature in the outer frame 3 of the cooking process, and the second insulation board 42 is made of high-density foam board to keep the temperature in the auxiliary bottom frame 41, thereby improving the cooking effect of rice and flour products.

[0050] The condensate generated during cooking falls into the auxiliary bottom frame 41 for collection. The cleaning water output system is activated, and the cleaning water is introduced into the connecting pipe 62 through the output port and the liquid guide main pipe 63. Then it is introduced into multiple liquid guide frames 61 and sprayed evenly on the lower surface of the conveyor belt 23 through multiple spray holes 601. With the automatic transmission of the conveyor belt 23 and the contact between the cleaning brush 64 and the lower surface of the conveyor belt 23, the cleaning brush 64 automatically cleans the lower surface of the conveyor belt 23 with the cleaning water. The wastewater generated during cleaning falls into the auxiliary bottom frame 41 for collection.

[0051] By controlling the drive block 44 to reciprocate within the auxiliary bottom frame 41, the scraper 43 is driven to reciprocate within the auxiliary bottom frame 41. Since the bottom end of the scraper 43 contacts the lower inner wall of the auxiliary bottom frame 41, and the side wall of the scraper 43 contacts the inner side wall of the auxiliary bottom frame 41, the scraper 43 cleans the impurities attached to the inner wall of the auxiliary bottom frame 41. At the same time, the cleaned impurities, condensate, and wastewater are automatically discharged into the collection hopper frame 5 through the waste discharge channel 401 and discharged through the waste discharge pipe 51, thereby automatically cleaning the collected condensate, wastewater, and impurities.

[0052] Working principle: In use, connect the end of the liquid guide pipe 63 to the output port of the cleaning water output system, control the first motor 24 to drive the corresponding transmission roller 22 to rotate, thereby driving the transmission belt 23 to carry out transmission. While the transmission roller 22 rotates, in conjunction with the transmission of the second sprocket 46, the third sprocket 461 and the second chain 462, control one of the auxiliary shafts 45 to rotate, drive the first sprocket 451 to rotate and drive the first chain 452 to carry out transmission, thereby driving the drive shaft 453 to carry out transmission. Since the drive shaft 453 is movably engaged in the corresponding drive longitudinal groove 441, the drive shaft 453 transmission control drive block 44 moves back and forth in the auxiliary bottom frame 41.

[0053] The rice and flour products to be steamed are placed on the conveyor belt 23. As the conveyor belt 23 is transported, the rice and flour products are transported in a track-like manner. Multiple partitions 34 divide the outer frame 3 of the steaming into multiple steaming chambers. Each steaming chamber is equipped with a steam spray frame 35. The external steam generator is controlled to input steam into the steam spray frame 35, so that steam at different temperatures is delivered to each steaming chamber through multiple steam spray frames 35. This allows the rice and flour products transported on the conveyor belt 23 to be continuously preheated and steamed at different temperatures, so that the multiple rice and flour products are heated evenly, improving the taste and processing quality of the rice and flour products, and increasing the steaming efficiency of the rice and flour products.

[0054] The first insulation board 32 is made of high-density foam board to keep the temperature in the outer frame 3 of the cooking process, and the second insulation board 42 is made of high-density foam board to keep the temperature in the auxiliary bottom frame 41, thereby improving the cooking effect of rice and flour products.

[0055] The steaming and cooking effect of rice and flour products in the outer frame 3 can be observed through observation window 33.

[0056] The condensate generated during cooking falls into the auxiliary bottom frame 41 for collection. The cleaning water output system is activated, and the cleaning water is introduced into the connecting pipe 62 through the output port and the liquid guide main pipe 63. Then it is introduced into multiple liquid guide frames 61 and sprayed evenly on the lower surface of the conveyor belt 23 through multiple spray holes 601. With the automatic transmission of the conveyor belt 23 and the contact between the cleaning brush 64 and the lower surface of the conveyor belt 23, the cleaning brush 64 automatically cleans the lower surface of the conveyor belt 23 with the cleaning water. The wastewater generated during cleaning falls into the auxiliary bottom frame 41 for collection.

[0057] By controlling the drive block 44 to reciprocate within the auxiliary bottom frame 41, the scraper 43 is driven to reciprocate within the auxiliary bottom frame 41. Since the bottom end of the scraper 43 contacts the lower inner wall of the auxiliary bottom frame 41, and the side wall of the scraper 43 contacts the inner side wall of the auxiliary bottom frame 41, the scraper 43 cleans the impurities attached to the inner wall of the auxiliary bottom frame 41. At the same time, the cleaned impurities, condensate, and wastewater are automatically discharged into the collection hopper frame 5 through the waste discharge channel 401 and discharged through the waste discharge pipe 51, thereby automatically cleaning the collected condensate, wastewater, and impurities.
