Description

Technical Field

[0001] This solution belongs to the technical field of food processing equipment, specifically involving a steaming mill. Background Technology

[0002] Referring to the background technology in the existing publication (announcement) number CN113142462A, a steaming mill is a processing equipment suitable for foods made from glutinous rice, such as mochi, rice cakes, and green rice dumplings, as well as puffed foods with ingredients like rice crackers and senbei. Its main principle is to place powder and water in the steaming mill and stir them. During the stirring process, high-temperature steam is introduced, heating the mixture of powder and water until it becomes cooked, which is then used for further processing. This avoids steaming the food after it has been shaped, preventing uneven heating between the surface and the interior, which can lead to inconsistent cooking and defects such as aging, cracking, and lack of elasticity.

[0003] Refer to the existing public disclosure (announcement) number CN111194937A for a vertical steam mill, which includes a frame, a steam mill barrel, a drive motor, a steam inlet pipe, and a stirring mechanism. The steam mill barrel is mounted on the frame. One end of the stirring mechanism extends into the bottom of the steam mill barrel, and the other end extends out of the steam mill barrel and is connected to the drive motor. The steam mill barrel is provided with at least two steam inlets, which are located at the lower or middle part of the steam mill barrel. The steam inlet pipe is connected to the steam inlets. The upper end of the steam mill barrel is provided with an exhaust port, and the lower end of the steam mill barrel is provided with a discharge port, which is equipped with a discharge valve.

[0004] Since the steaming barrel in the aforementioned steaming mill is directly fixed on the frame, after the material inside the barrel is steamed, the material can only be discharged from the top discharge port, making it difficult to remove and unload the steamed material. Utility Model Content

[0005] The purpose of this solution is to provide a steam mill that solves the problem of unloading material in existing steam mills.

[0006] To achieve the above objectives, this solution provides a steaming mill, including a frame and a steaming barrel mounted on the frame. The steaming barrel is equipped with a stirring device and a steam inlet pipe, and the side wall of the steaming barrel is rotatably connected to the frame.

[0007] The principle of this solution is as follows: since the steaming drum and the frame are rotatably connected, when it is necessary to feed the steaming drum, the steaming drum is fixed vertically on the frame, and when it is necessary to unload the steaming drum, the steaming drum is rotated so that the feed port of the steaming drum tilts downward and the material inside the drum is poured out.

[0008] The advantages of this solution are: by rotating the steaming drum to the frame, it solves the problem of difficult material unloading in existing steaming mills. When unloading is required, the steaming drum can be rotated to tilt the feed inlet downwards, thus facilitating the pouring of materials inside the drum. This avoids the blockage and incomplete unloading problems caused by materials only being discharged from the top discharge port, thereby improving the efficiency and convenience of unloading.

[0009] Furthermore, it also includes a drive assembly mounted on the frame. The drive assembly includes a drive motor and a worm gear. The output shaft of the drive motor is fixedly connected to a drive wheel, and one end of the worm gear is fixedly connected to a first driven wheel. The drive wheel and the first driven wheel are connected by a first belt drive. The worm gear is rotatably connected to the frame. The rotating shaft of the steaming tank is fixedly connected to an incomplete worm wheel, which meshes with the worm gear.

[0010] The principle and effect of this scheme are as follows: (1) The drive motor drives the active wheel to rotate, the active wheel drives the first driven wheel to rotate through the first belt, and the first driven wheel drives the worm to rotate, thereby driving the incomplete worm wheel to rotate, and thus driving the steaming barrel to rotate. (2) Through the above settings, the steaming barrel is driven to rotate by the drive motor, thereby avoiding manual rotation of the steaming barrel and improving production efficiency.

[0011] Furthermore, the stirring device includes a stirring motor and a drive shaft. The output shaft of the stirring motor is fixedly connected to a drive gear, and a driven gear is fixedly passed through the drive shaft. The drive gear and the driven gear are connected by a chain drive, and the drive shaft is rotatably connected to the frame. A drive wheel is fixedly passed through the drive shaft, and a second driven wheel is passed through the shaft. The drive wheel and the second driven wheel are connected by a second belt drive. A stirring roller is fixedly connected coaxially to the shaft.

[0012] The principle and effect of this solution are as follows: the stirring motor drives the drive gear to rotate, the drive gear drives the driven gear to rotate through the chain, thereby causing the drive shaft to rotate, the drive shaft drives the drive wheel to rotate, the drive wheel drives the second driven wheel to rotate through the second belt, thereby causing the rotating shaft of the steaming barrel to rotate, and then causing the stirring roller to rotate to stir and mix the materials in the steaming barrel.

[0013] Furthermore, the stirring device also includes a tensioning assembly, which includes a support plate and a tensioning wheel. The support plate is fixedly mounted on the frame and has a through groove. A locking bolt is slidably mounted in the through groove. The tensioning wheel is locked and fixed to the support plate by the locking bolt. The tensioning wheel is used to tension the second belt.

[0014] The principle and effect of this solution are as follows: Because belt drives experience wear, aging, or temperature changes that reduce their tension, thus affecting transmission efficiency and stability, it is necessary to tension the second belt. In this solution, when tensioning the second belt is required, the locking bolt is loosened, and the nut of the locking bolt is moved within the through groove. This moves the tensioning pulley, causing it to contact the second belt, thereby adjusting the tension of the second belt.

[0015] Furthermore, it also includes a sealing device mounted on the frame. The sealing device includes a top cover and a handwheel. The top cover is used to seal the feed inlet of the steaming barrel. The top cover is rotatably connected to a lead screw. The free end of the lead screw is fixedly connected to the handwheel. The lead screw is connected to the frame by a thread.

[0016] The principle and effect of this solution are as follows: Since high-temperature steam needs to be introduced into the steaming tank, a sealing device is installed to prevent air leakage from the feed inlet of the steaming tank during material mixing. When material needs to be poured into the steaming tank, the handwheel is turned, causing the screw to rotate and thus moving the top cover away from the feed inlet, opening the feed inlet. Material is then poured into the steaming tank through the feed inlet. When steaming is required, the handwheel is turned in the opposite direction, causing the screw to rotate in the opposite direction, thus causing the top cover to contact and press against the feed inlet, sealing the feed inlet and preventing air leakage.

[0017] Furthermore, it also includes a rotating device mounted on the frame, which is used to drive the top cover to rotate; the rotating device includes a rotating motor and a reducer, the output end of the rotating motor is fixedly connected to the input end of the reducer, the output end of the reducer is fixedly connected to a bracket, and the free end of the bracket is rotatably connected to the top cover.

[0018] The principle and effect of this solution are as follows: Since the steaming drum needs to rotate to discharge material, the top cover also needs to rotate with the steaming drum. In this solution, a rotating motor drives the reducer shaft to rotate, which in turn drives one end of the support to rotate, thereby causing the top cover to rotate. When the steaming drum rotates, the rotating motor is controlled to rotate, so that the top cover rotates synchronously with the steaming drum.

[0019] Furthermore, the steam inlet pipe is connected to a steam generator, the outlet of the steam inlet pipe is located inside the steaming barrel, and the steam inlet pipe is equipped with a pressure gauge, a pressure relief valve, and a switching valve.

[0020] The principle and effect of this scheme are as follows: (1) The steam generator generates steam and sends the steam into the steaming tank through the steam inlet pipe. While stirring, the mixture of powder and water is heated until the mixture becomes clinker, and then it is processed and manufactured. (2) The pressure gauge is used to monitor the steam pressure inside the steaming tank; the pressure relief valve automatically opens when the pressure is too high to release the excess pressure; the switch valve is used to control the steam flow.

[0021] Furthermore, it also includes a control system, which includes a controller electrically connected to a pressure gauge, a pressure relief valve, and a switching valve, and electrically connected to a drive motor, a stirring motor, and a rotating motor.

[0022] The principle and effect of this solution are as follows: the control system controls the drive motor, thereby controlling the rotation of the steaming tank; the control motor controls the speed of the stirring roller turning the material; and the control motor controls the rotation of the top cover. The controller controls the opening and closing of the pressure relief valve and the flow rate of the on / off valve based on the values ​​read from the pressure gauge.

[0023] Furthermore, the stirring roller includes a first stirring rod and a second stirring rod, the second stirring rod being slidably disposed inside the first stirring rod, the second stirring rod being connected to a return spring, the free end of the return spring being fixedly connected to the first stirring rod; a stirring spatula is fixedly connected to the free end of the second stirring rod.

[0024] The principle and effect of this solution are as follows: Because the material is stirred inside the steaming drum, wet material easily adheres to the inner wall of the drum and dries there after steaming, making it difficult to clean. Therefore, it is necessary to clean the inner wall of the steaming drum during the steaming process to reduce the problem of the material drying and sticking to the inner wall later. In this solution, the controller periodically increases the speed of the stirring motor, causing the second stirring rod to be thrown out of the first stirring rod by a large centrifugal force, and the return spring is stretched. After the second stirring rod is thrown out, the stirring shovel contacts the inner wall of the steaming drum, and under the condition of the relatively high speed of the stirring roller, the material adhering to the inner wall of the drum is scraped off.

[0025] Furthermore, the stirring shovel has a groove, a positioning bolt is slidably disposed in the groove, a cleaning shovel is slidably disposed on the stirring shovel, the cleaning shovel is fixedly connected to the positioning bolt, a spring is fixedly connected to the positioning bolt, and the free end of the spring is fixedly connected to the groove.

[0026] The principle and effect of this solution are as follows: Although the mixing shovel is used to scrape and clean materials, this also leads to material adhering to the shovel. When a large amount of material adheres to the shovel, the cleaning effect will be poor during the next scraping. Additionally, material will still adhere to the shovel after steaming. Therefore, it is necessary to clean the material adhering to the shovel regularly. When the speed of the mixing motor increases, the cleaning shovel is subjected to a greater centrifugal force, causing the positioning bolt to move to its maximum stroke within the groove and stretching the spring. When the speed of the mixing motor returns to normal, the spring drives the cleaning shovel to reciprocate, causing the cleaning shovel to slide into contact with the mixing shovel, thereby scraping away the material adhering to the mixing shovel. Simultaneously, because the cleaning shovel and the mixing shovel are in mutual sliding contact, material adhering to the cleaning shovel can also be removed. Attached Figure Description

[0036] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model.

[0037] Example 1:

[0038] Please see 1 and Figure 2 A steaming mill includes a frame 1 with adjustable casters at the bottom. A steaming drum 2 is rotatably mounted on the frame 1. A drive assembly 21 for driving the steaming drum 2 to rotate is mounted on the frame 1. The drive assembly 21 includes a drive motor 211 and a worm gear 212. The output shaft of the drive motor 211 is fixedly connected to a drive wheel 213. One end of the worm gear 212 is fixedly connected to a first driven wheel 214. The drive wheel 213 and the first driven wheel 214 are connected by a first belt 215. The worm gear 212 is rotatably connected to the frame 1. An incomplete worm wheel 216 is fixedly connected to the rotating shaft 22 of the steaming drum 2. The incomplete worm wheel 216 meshes with the worm gear 212. After the material in the steaming drum 2 has been steamed, the drive motor 211 drives the drive wheel 213 to rotate. The drive wheel 213 drives the first driven wheel 214 to rotate via the first belt 215. The first driven wheel 214 drives the worm gear 212 to rotate, which in turn drives the incomplete worm wheel 216 to rotate, thereby rotating the steaming drum 2. This causes the feed inlet of the steaming drum 2 to tilt downwards, emptying the material inside the drum. This avoids the need for manual rotation of the steaming drum 2 and improves production efficiency. At the same time, the incomplete worm wheel 216 limits the rotation range of the steaming drum 2 and also causes the rotation angle of the steaming drum 2 to be too large.

[0039] Please see Figure 3 and Figure 4 The system also includes a stirring device 3 mounted on the frame 1. The stirring device 3 includes a stirring motor 31 and a drive shaft 32. The output shaft of the stirring motor 31 is fixedly connected to a drive gear 33, and the drive shaft 32 is fixedly connected to a driven gear 34. The drive gear 33 and the driven gear 34 are connected by a chain 35. The drive shaft 32 is rotatably connected to the frame 1. A set of symmetrically arranged drive wheels 36 are fixedly arranged on the drive shaft 32, and a set of symmetrically arranged second driven wheels 37 are arranged on the rotating shaft 22. The drive wheels 36 and the second driven wheels 37 are connected by a second belt 38. A stirring roller 39 is coaxially fixedly connected to the rotating shaft 22. The stirring motor 31 drives the drive gear 33 to rotate, and the drive gear 33 drives the driven gear 37 to rotate through the chain 35, thereby causing the drive shaft 32 to rotate. The rotation of the drive shaft 32 drives the drive wheels 36 to rotate, and the drive wheels 36 drive the second driven wheels 37 to rotate through the second belt 38, thereby causing the rotating shaft 22 of the steaming tank 2 to rotate, which in turn causes the stirring roller 39 to rotate and stir the materials in the steaming tank 2.

[0040] Because the tension of the second belt 38 decreases due to wear, aging, or temperature changes, thus affecting transmission efficiency and stability, it is necessary to tension the second belt 38. The mixing device 3 also includes a tensioning assembly 310, which includes a support plate 3101 and a tensioning wheel 3102. The support plate 3101 is fixed to the frame 1 and has a through groove 3103. A locking bolt 3104 is slidably disposed within the through groove 3103. The tensioning wheel 3102 is locked and fixed to the support plate 3101 by the locking bolt 3104. The tensioning wheel 3102 is used to tension the second belt 38. When it is necessary to tension the second belt 38, the locking bolt 3104 is loosened, and the nut of the locking bolt 3104 is moved within the through groove 3103, thereby moving the tensioning wheel 3102. This causes the tensioning wheel 3102 to contact the second belt 38, thus adjusting the tension of the second belt 38.

[0041] Because high-temperature steam needs to be introduced into the steaming tank 2, a sealing device 5 is installed to prevent air leakage from the feed inlet of the steaming tank 2 during the mixing process. The sealing device 5, mounted on the frame 1, includes a top cover 51 and a handwheel 52. The top cover 51 is used to close the feed inlet of the steaming tank 2. A lead screw is rotatably connected to the top cover 51, and the free end of the lead screw is fixedly connected to the handwheel 52. The lead screw is threadedly connected to the frame 1. When material needs to be poured into the steaming tank 2, the handwheel 52 is turned, causing the lead screw to rotate, which moves the top cover 51 away from the feed inlet of the steaming tank 2, opening the feed inlet. Material is then poured into the steaming tank 2 through the feed inlet. When steaming is required, the handwheel 52 is turned in the opposite direction, causing the lead screw to rotate in the opposite direction, which causes the top cover 51 to contact and press against the feed inlet, sealing the feed inlet and preventing air leakage.

[0042] Please see Figure 5 It also includes a rotating device 6 mounted on the frame 1, which drives the top cover 51 to rotate. The rotating device 6 includes a rotating motor 61 and a reducer 62. The output end of the rotating motor 61 is fixedly connected to the input end of the reducer 62, and a bracket 63 is fixedly connected to the output end of the reducer 62. The free end of the bracket 63 is rotatably connected to the top cover 51. Since the steaming drum 2 needs to rotate to discharge material, the top cover 51 also needs to rotate with the steaming drum 2. The rotating motor 61 drives the reducer 62 shaft to rotate, which in turn drives one end of the bracket 63 to rotate, thereby causing the top cover 51 to rotate. When the steaming drum 2 rotates, the rotating motor 61 is controlled to rotate, so that the top cover 51 rotates synchronously with the steaming drum 2.

[0043] Please see Figure 6A steam inlet pipe 4 is connected to a steam generator (not shown in the figure). The outlet of the steam inlet pipe 4 is located inside the steaming barrel 2. The steam inlet pipe 4 is equipped with a pressure gauge 41, a pressure relief valve 42, and a switching valve 43. The steam generator produces steam and sends it into the steaming barrel 2 through the steam inlet pipe 4. The mixture of powder and water is heated while being stirred until it becomes clinker for further processing. The pressure gauge 41 is used to monitor the steam pressure inside the steaming barrel 2. The pressure relief valve 42 automatically opens when the pressure is too high to release excess pressure. The switching valve 43 is used to control the flow of steam. A control system 7 is also included. The control system 7 includes a controller, which is electrically connected to the pressure gauge 41, the pressure relief valve 42, and the switching valve 43. The controller is also electrically connected to the drive motor 211, the stirring motor 31, and the rotating motor 61. The control system 7 controls the drive motor 211, thereby controlling the rotation of the steaming tank 2; it controls the stirring motor 31 to control the turning speed of the stirring roller 39; and it controls the rotation motor 61 to control the rotation of the top cover 51. The controller controls the opening and closing of the pressure relief valve 42 and the flow rate of the switching valve 43 based on the value read from the pressure gauge 41.

[0044] Example 2:

[0045] Because the materials are stirred inside the steaming tank 2, the wet materials easily adhere to the inner wall of the steaming tank, and after steaming, they dry on the inner wall, making them difficult to clean. Therefore, this embodiment requires cleaning the inner wall of the steaming tank 2 during the steaming process to reduce the problem of cleaning difficulties caused by the dried materials sticking to the inner wall later.

[0046] Please see Figure 7 and Figure 8 The stirring roller 39 includes a first stirring rod 391 and a second stirring rod 392. The second stirring rod 392 is slidably disposed inside the first stirring rod 391. A return spring (not shown in the figure, disposed inside the first stirring rod 391) is connected to the second stirring rod 392. The free end of the return spring is fixedly connected to the first stirring rod 391. A stirring shovel 393 is fixedly connected to the free end of the second stirring rod 392. By periodically increasing the speed of the stirring motor 31 through the controller, the second stirring rod 392 is subjected to a large centrifugal force and thrown out of the first stirring rod 391, stretching the return spring. After the second stirring rod 392 is thrown out, the stirring shovel 393 contacts the inner wall of the steaming barrel 2. Under the condition of the relatively fast rotation speed of the stirring roller 39, the material adhering to the inner wall of the barrel is scraped off.

[0047] Although the stirring spatula 393 is used to scrape and clean materials, this also leads to material adhering to the spatula 393. When there is a lot of material adhering to the stirring spatula 393, the cleaning effect will be poor during the next scraping. Additionally, material will also adhere to the stirring spatula 393 after steaming. Therefore, it is necessary to clean the material adhering to the stirring spatula 393 regularly. The stirring spatula 393 has a groove 3931, within which a positioning bolt 394 is slidably mounted. A cleaning spatula 395 is slidably mounted on the stirring spatula 393, and is fixedly connected to the positioning bolt 394. A spring 396 is fixedly connected to the positioning bolt 394, and the free end of the spring 396 is fixedly connected to the groove 3931. When the speed of the stirring motor 31 increases, the cleaning spatula 393 experiences a greater centrifugal force, causing the positioning bolt 394 to move to its maximum stroke within the groove 3931, thus stretching the spring 396. Once the stirring motor 31 returns to normal speed, the spring 396 drives the cleaning shovel 395 to reciprocate, causing the cleaning shovel 395 to slide into contact with the stirring shovel 393, thereby scraping away the material adhering to the stirring shovel 393. Simultaneously, because the cleaning shovel 395 and the stirring shovel 393 are in sliding contact with each other, the material adhering to the cleaning shovel 395 can also be cleaned.

[0048] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
