Description
Technical Field
[0001] This utility model relates to the technical field of steamed bun proofing and steaming machines, specifically a multifunctional variable-station deformable tunnel pasta equipment. Background Technology
[0002] In the industrial production of pasta, the integrated proofing and steaming machine is the core equipment that integrates the proofing and steaming processes. It is used to perform a second proofing and steaming of the dough under a specific temperature and humidity environment after the first proofing and shaping of the dough. This makes the steamed buns made from the dough have better elasticity, thereby improving the taste of the steamed buns after industrial production. However, the traditional integrated proofing and steaming machine has shortcomings in practical application. We propose a multi-functional variable station deformable tunnel pasta equipment.
[0003] The existing technology still has the following drawbacks in its use:
[0004] In existing pasta equipment, when using high-temperature steam to proof dough, the steam is concentrated at the bottom of the steamer and gradually spreads upward and outward in the form of a mushroom cloud during the steaming process. However, because the heat is concentrated in the middle, the steam in the middle rises faster and the temperature in the middle is higher than that in the surrounding areas. This results in uneven heating of the dough in different positions on the same steamer, which not only affects the proofing and steaming effect of the steamed buns, but also causes heat loss and reduces the utilization rate of the heat in the steam by the device.
[0005] In existing pasta equipment, the dough undergoes a second proofing and steaming process using two separate steam mechanisms. This results in high energy consumption during the steam generation step and less than ideal steam utilization.
[0006] In view of this, we propose a multifunctional, variable-station, deformable tunnel pasta-making equipment to solve the existing problems. Utility Model Content
[0007] The purpose of this invention is to provide a multifunctional, variable-position, deformable tunnel pasta-making equipment to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional variable-station deformable tunnel pasta equipment, including a proofing and steaming assembly, an installation box, a conveyor frame and a drive box.

[0009] The proofing and steaming components are fixedly installed inside the installation box;
[0010] A conveyor frame is fixedly installed on the right side of the mounting box. A transmission belt is installed on the inner side of the conveyor frame through several transmission shafts. A transmission mesh plate is provided on the top of the transmission belt.
[0011] A mounting frame is fixedly installed on one side of the top of the conveyor frame. A dual-axis drive mechanism is installed on the top of the mounting frame, and a clamp is installed at the bottom of the dual-axis drive mechanism via a cylinder.
[0012] A drive box is fixedly installed on the top back of the conveyor frame, and a conveyor belt is driven to the front of the drive box. The conveyor belt is arranged in a front-to-back direction and is located inside the mounting frame.
[0013] Preferably, the steaming assembly includes a water tank, a controller is fixedly installed on one side of the water tank, and a heating tube is fixedly installed on one side of the controller. The heating tube extends into the interior of the water tank and is arranged in a serpentine pattern inside the water tank. A water injection pipe is fixedly installed on the side of the water tank near the top, and a cover plate is snapped onto the top of the water tank.
[0014] Preferably, an installation plate is fixedly installed inside the cover plate, and a temperature sensor and a humidity sensor are respectively installed on the bottom of the installation plate. An air pump is fixedly installed on one side of the top of the cover plate, and a connecting pipe is fixedly installed at the output end of the air pump. Two guide pipes are fixedly installed on the inner side of the connecting pipe, and a 45-degree angle is provided between the guide pipes and the connecting pipe.
[0015] Preferably, a diffuser is fixedly installed on the top of the cover plate, and the diffuser has a trumpet-shaped structure that is wider at the top and narrower at the bottom, and the guide tube extends into the interior of the diffuser.
[0016] Preferably, a connecting plate is fixedly installed on the top of the diffuser cylinder, and several guide pipes are fixedly installed on the top of the connecting plate. The bottom of the connecting plate is connected to the diffuser cylinder, and several exhaust holes connected to the guide pipes are opened on the top of the connecting plate.
[0017] Preferably, the lengths of the several guide tubes on the top of the connecting plate are not uniform, and the length of the guide tubes near the edge is greater than that of the guide tubes near the center. The length of the guide tubes increases gradually from the center to the edge, and the tops of the several guide tubes form a concave arc surface structure.
[0018] Preferably, several lifting frames are slidably installed on the front and rear sides of the interior of the steaming box, and the lifting frames are connected by chains.

[0019] Preferably, a temperature sensor and a humidity sensor are fixedly installed on the inner wall of the protective curtain, and the bottom of the protective curtain is installed higher than the installation position of the conveyor belt.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] This invention, by installing several guide tubes of varying lengths on the top of the connecting plate, allows steam to enter the guide tubes simultaneously. The steam in the central part is preferentially discharged from the guide tube and begins to diffuse, while the steam in the surrounding parts is discharged later after its discharge path is extended by the guide tubes. This results in steam from different parts being discharged at different heights, changing the diffusion pattern of the steam. This facilitates the even transfer of the heat carried by the steam to each dough ball, ensuring the device's effectiveness in proofing and steaming the dough.
[0022] This invention features a steaming and proofing assembly installed inside the mounting box. Multiple transfer mesh plates containing dough are arranged longitudinally, and the same steaming and proofing assembly transmits high-temperature steam to the upper transfer mesh plates. The dough to be proofed is placed at a higher position, and the dough to be steamed is placed at a lower position. This allows the high-temperature steam to preferentially contact the dough to be steamed. After the heat is absorbed by the dough at the bottom, the cooled steam rises to a higher position for low-temperature proofing of the dough. This improves the utilization rate of high-temperature steam, reduces the number of steam generating structures, lowers the overall energy consumption of the device, and enables it to achieve multi-functionality.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0032] like Figures 1-7 As shown, this utility model proposes a multifunctional variable-station deformable tunnel pasta equipment, including a proofing and steaming component 1, a mounting box 2, a conveyor frame 3, and a drive box 4. A proofing and steaming box 202 is fixedly mounted on the top of the mounting box 2, and protective curtains 203 are fixedly mounted on both the left and right sides of the proofing and steaming box 202. An electrical cover 201 is fixedly mounted on the outer top of the proofing and steaming box 202. A control box 204 is fixedly mounted on the back of the mounting box 2. The mounting box 2 provides mounting positions for surrounding components. The proofing and steaming box 202 can be used to longitudinally arrange the conveyor mesh 301, thereby utilizing high-temperature steam to… The dough placed on the conveyor belt 301 is proofed or steamed. The protective curtain 203 can cover the left and right sides of the proofing and steaming box 202, thereby guiding the high-temperature steam to rise and concentrate the high-temperature steam in the proofing and steaming box 202, preventing it from being discharged from the left and right sides of the proofing and steaming box 202 and thus reducing the proofing and steaming effect. The electrical cover 201 can protect the internal components, thereby preventing foreign objects from being caught in the transmission structure inside the electrical cover 201 during operation, which could cause the equipment to jam and be damaged. The control box 204 can connect other electronic components through cables, thereby enabling the device to operate automatically.
[0033] The internal part of the installation box 2 is fixedly installed with a proofing and steaming component 1. The proofing and steaming component 1 can use high-temperature steam to proof or steam the dough. Thus, within the same device, by arranging different types of dough, the high-temperature steam can process different doughs separately during the rising process, realizing multi-functional proofing and steaming processing.
[0034] A conveyor frame 3 is fixedly installed on the right side of the mounting box 2. A transmission belt 302 is installed on the inner side of the conveyor frame 3 via several transmission shafts. A transfer mesh plate 301 is set on the top of the transmission belt 302. The conveyor frame 3 can provide installation positions for the surrounding components. The transmission belt 302 can be driven to roll by the transmission shafts. A servo motor is installed at one end of the transmission shaft. The servo motor is fixedly connected to the inner wall of the conveyor frame 3. The servo motor is a YE4-100KW type. When the servo motor is powered on and rotates, it drives the transmission shaft to rotate, so that the transmission belt 302 drives the transfer mesh plate 301 to move horizontally, so as to facilitate the translation of the dough.
[0035] A mounting frame 5 is fixedly installed on one side of the top of the conveyor frame 3. A dual-axis drive mechanism 502 is installed on the top of the mounting frame 5, and a clamp 501 is installed at the bottom of the dual-axis drive mechanism 502 via a cylinder. The mounting frame 5 can provide mounting positions for the surrounding components. The dual-axis drive mechanism 502 can move the clamp 501 in both left and right and up and down directions, thereby enabling the batch clamping of dough on the top of the conveyor belt 401, so that the dough can be moved from the conveyor belt 401 to the top of the transfer mesh plate 301, so that the dough can be sent into the proofing and steaming box 202 along with the transfer mesh plate 301 for proofing and steaming.
[0036] A drive box 4 is fixedly installed on the top back of the conveyor frame 3, and a conveyor belt 401 is driven to the front of the drive box 4. The conveyor belt 401 is arranged in a front-to-back direction and is located inside the mounting frame 5. A servo motor is installed inside the drive box 4. The servo motor is a YE4-100KW type. The servo motor drives the conveyor belt 401 to work when it is powered on. The conveyor belt 401 can continuously transport the dough to the bottom of the clamp 501, so that the clamp 501 can transfer the dough and arrange the dough steam on the top of the transfer mesh plate 301 for subsequent proofing and steaming of the dough.
[0037] Furthermore, the proofing and steaming assembly 1 includes a water tank 105. A controller 107 is fixedly installed on one side of the water tank 105, and a heating tube 106 is fixedly installed on one side of the controller 107. The heating tube 106 extends into the interior of the water tank 105 and is arranged in a serpentine pattern inside the water tank 105. A water injection pipe 108 is fixedly installed on the side of the water tank 105 near the top. A cover plate 109 is snapped onto the top of the water tank 105. The water tank 105 can store a certain amount of clean water, so that it can generate high-temperature steam after heating, so as to use the high-temperature steam to proof the dough. The controller 107 can be connected to an external power source to control the power supply to the heating tube 106, so that the heating tube 106 generates heat to heat the water inside the water tank 105 after being powered on. The water injection pipe 108 can be connected to an external water pipe to add clean water to the interior of the water tank 105. The cover plate 109 can provide a position for the top assembly to be installed.
[0038] Furthermore, a mounting plate 104 is fixedly installed inside the cover plate 109, and a temperature sensor and a humidity sensor are respectively installed on the bottom of the mounting plate 104. A vacuum pump 102 is fixedly installed on one side of the top of the cover plate 109, and a connecting pipe 110 is fixedly installed at the output end of the vacuum pump 102. Two guide pipes 112 are fixedly installed on the inner side of the connecting pipe 110, and the guide pipes 112 and the connecting pipes 110 are at a 45-degree angle. The mounting plate 104 provides a mounting position for the temperature sensor and humidity sensor at the bottom. The temperature sensor is a PT100 type, and the humidity sensor is an RS485 type. The temperature sensor and humidity sensor monitor the temperature and humidity inside the proofing chamber 202. The ambient temperature and humidity near the top of the device are monitored, enabling the device to adjust the temperature and emission rate of the high-temperature steam in conjunction with the temperature. This provides a suitable proofing environment for the dough that needs to proof on the upper layer. The ambient temperature is adjusted to 35 to 40 degrees Celsius, and the humidity is controlled between 75% and 85%, thus ensuring the proofing effect of the dough. The vacuum pump 102 is an N86KNE type, which can draw in the high-temperature steam inside the water tank 105 and transfer the high-temperature steam to the inside of the diffuser 103 through the connecting pipe 110 and the guide pipe 112. With the help of the guide pipe, the high-temperature steam rises in a spiral shape inside the diffuser 103, which increases the diffusion speed and diffusion area of the steam.
[0039] Furthermore, a diffuser cylinder 103 is fixedly installed on the top of the cover plate 109, and the diffuser cylinder 103 has a trumpet-shaped structure that is wider at the top and narrower at the bottom. The guide tube 112 extends into the interior of the diffuser cylinder 103. The diffuser cylinder 103 can work with the guide tube 112 to rapidly diffuse the high-temperature steam inside and expand the diffusion range of the steam, so that the high-temperature steam enters the interior of the connecting plate 111 evenly.
[0040] Furthermore, a connecting plate 111 is fixedly installed on the top of the diffuser 103, and several guide pipes 101 are fixedly installed on the top of the connecting plate 111. The bottom of the connecting plate 111 is connected to the diffuser 103, and several exhaust holes connected to the guide pipes 101 are opened on the top of the connecting plate 111. The connecting plate 111 can guide the high-temperature steam, so that the high-temperature steam enters each guide pipe 101 evenly and diffuses upward.
[0041] Furthermore, the lengths of the several guide tubes 101 on the top of the connecting plate 111 are not uniform, and the length of the guide tubes 101 near the edge is greater than that of the guide tubes 101 near the center. The length of the guide tubes 101 gradually increases from the center to the edge, and the tops of the several guide tubes 101 form a concave arc structure. The guide tubes 101 can achieve uniform diffusion of high-temperature steam. By setting guide tubes 101 of different lengths, the high-temperature steam at the perimeter is delayed in its discharge and diffusion, while the steam in the center is preferentially discharged from the shorter guide tubes 101 and begins to diffuse. After the steam in the center diffuses to a certain extent, it converges with the high-temperature steam discharged from the longer guide tubes 101 and then diffuses upward together. This ensures that the overall steam heating effect on the dough on the transfer mesh plate 301 is maintained, so that the heating degree of each dough is consistent, avoiding the uneven heating of the dough caused by traditional steaming methods, which affects the proofing and steaming effect of the dough.
[0042] Furthermore, several lifting frames 207 are slidably installed on the front and rear sides of the interior of the proofing and steaming box 202, and the lifting frames 207 are connected by chains. A motor 206 is fixedly installed on the top of the proofing and steaming box 202, and a transmission chain 205 is fitted on the outside of the output shaft of the motor 206. The transmission chain 205 is connected to the chain on the outside of the lifting frame 207 through a rotating roller. The lifting frame 207 can drive the transfer mesh plate 301 carrying the dough to move vertically, thereby arranging several groups of dough in a longitudinal direction. This allows the high-temperature steam to steam the dough at the bottom layer and proof the dough at the top layer during the rising process. The motor 206 is a YE3-200KW type. After the motor 206 is powered on, it can rotate, thereby driving multiple groups of lifting frames 207 to move vertically through the chain and transmission chain 205, so as to facilitate the longitudinal movement of the transfer mesh plate 301.
[0043] Furthermore, a temperature sensor and a humidity sensor are fixedly installed on the inner wall of the protective curtain 203, and the bottom of the protective curtain 203 is installed higher than the installation position of the conveyor belt 401. The temperature sensor adopts the PT100 type, and the humidity sensor adopts the RS485 type. By detecting the ambient temperature and humidity of the area near the top inside the proofing chamber 202 through the temperature sensor and humidity sensor, the device can be linked to adjust the temperature and exhaust speed of the high-temperature steam, thereby providing a suitable proofing environment for the dough that needs to be proofed in the upper layer, adjusting the ambient temperature to 35 to 40 degrees Celsius, and controlling the humidity between 75% and 85%, thereby ensuring the proofing effect of the dough.
[0044] Working principle: After the device is assembled, the untreated dough is moved by the conveyor belt 401 to the area below the clamp 501. The clamp 501 is moved by the dual-shaft drive mechanism 502, moving the dough in batches from the top of the conveyor belt 401 onto the transfer mesh plate 301 for arrangement. The transmission belt 302 pushes the transfer mesh plate 301 horizontally, moving it into the proofing chamber 202, where it engages with the inner wall of the lifting frame 207. The lifting frame 207 drives several transfer mesh plates 301 to move longitudinally, arranging the dough longitudinally inside the proofing chamber 202. Two sets of temperature and humidity sensors detect the temperature and humidity inside the proofing chamber 202 and the water tank 105, respectively. After the heating tube 106 is powered on, it heats the clean water inside the water tank 105 to generate high-temperature steam. The suction pump then draws the high-temperature steam, which enters the two guide tubes 112 through the connecting tube 110 and is discharged into the diffuser 103. After being guided by the diffuser 103, the high-temperature steam rises in a spiral shape and enters the connecting plate 111. It is then guided out through several guide tubes 101. During the rising process, the high-temperature steam first contacts the dough at the bottom and steams it. After the dough at the bottom absorbs some heat, the cooled steam then proofs the dough at the top. Thus, the same proofing and steaming box 202 and proofing and steaming component 1 can simultaneously perform the proofing and steaming processes on dough at different parts.
[0045] The above specific embodiments are merely several preferred embodiments of this utility model.
