Abstract
Description
Technical Field
[0001] This invention relates to the field of dough fermentation equipment technology, and more specifically to a PLC control device for precise temperature and humidity regulation during proofing. Background Technology
[0002] The dough ferments using the respiration of yeast. The yeast breaks down the sugars in the flour into a large amount of carbon dioxide. These gases are wrapped by the gluten network, forming pores, which causes the dough to expand. During fermentation, flavor compounds are formed, creating the complex and profound aroma and flavor of bread. In order to control the dough fermentation process and prevent insufficient or excessive fermentation, it is essential to use dough proofing equipment to control the activity of yeast. First, existing dough fermentation equipment is more like an insulated box. After the dough is placed in the box, the yeast is kept at a suitable temperature for fermentation through insulation. Once the dough has fermented, if the temperature and humidity inside the box are not effectively controlled, the activity of the yeast cannot be reduced, and the dough is prone to over-fermentation, which affects the texture and taste. Secondly, in existing dough fermentation equipment, after the dough is placed, the bottom of the dough contacts the tray. During the fermentation process, because the contact area between the dough and the tray is relatively closed, the dough does not have sufficient contact with air, resulting in insufficient fermentation. This leads to a higher density at the bottom of the fermented bread, which affects the taste. Third, in the existing dough fermentation equipment, after fermentation is completed, the temperature inside the box gradually decreases. The humid air inside will condense into tiny water droplets when it cools down. These tiny water droplets aggregate to form a certain volume of liquid. When the contaminants remaining on the tray inside the box mix with the liquid, bacteria can easily grow, thus causing equipment contamination. In other words, the existing dough fermentation equipment does not have a certain cleaning function. Therefore, in order to solve the above problems, there is a need to provide a PLC control device for precise temperature and humidity regulation. Summary of the Invention
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a PLC control device for precise temperature and humidity regulation to solve the problems existing in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a PLC control device for precise temperature and humidity regulation during fermentation, comprising a fermentation chamber assembly, wherein a humidification component is fixedly installed at the bottom of the fermentation chamber assembly, and a placement component is also provided in the fermentation chamber assembly; The fermentation chamber assembly includes a PLC controller, and the humidification assembly includes an atomizing plate. The PLC controller controls and drives the atomizing plate to humidify the internal environment of the fermentation chamber assembly. The placement component includes end rods with adjustable height. Dough is placed on the end rod array. After the dough has fermented, the PLC controller controls the atomizing plate to be turned off to stop humidification.

[0007] Furthermore, the humidification component includes a water box, which is fixedly installed at the bottom of the fermentation chamber component. The front side of the water box is fixedly connected to the bottom side of the front chamber plate. A rear filter layer is provided between the rear side of the water box and the rear chamber plate. The water box stores purified water. The atomizing plate is installed in the water box. A rear air venting machine is also installed on the water box. Airflow enters the internal space of the water box from the rear filter layer and is discharged into the bottom space of the placement tray from the rear air venting machine. The placement tray is higher than the front air venting machine and the rear air venting machine.
[0008] Furthermore, the PLC controller is electrically connected to the heating element and controls the opening and closing of the heating element; the PLC controller is electrically connected to the front air intake fan and controls the opening and closing of the front air intake fan; the PLC controller is electrically connected to the atomizing plate and the rear air intake fan and controls the opening and closing of both; and the PLC controller is electrically connected to the exhaust fan and controls the opening and closing of the exhaust fan.
[0009] Furthermore, the end rods are evenly distributed in the placement tray and movably connected to it. The bottom of each end rod is fixed to the moving plate. Each of the four bottom corners of the moving plate is equipped with an electric cylinder. The drive shaft of each electric cylinder is fixedly connected to the four bottom corners of the moving plate. Each electric cylinder is fixedly installed on the water box. A protective cover is also fitted on the outside of each electric cylinder. The drive shaft of each electric cylinder passes through the protective cover and movably connected to it.
[0010] Furthermore, a lower laser generator is provided on the inner side of the left side plate, and an upper laser generator is provided above the lower laser generator. A lower receiver is provided on the inner side of the right side plate, and an upper receiver is provided above the lower receiver. The optical signal of the lower laser generator is received by the lower receiver, and the optical signal of the upper laser generator is received by the upper receiver.
[0011] Furthermore, the PLC controller is electrically connected to the electric cylinder and controls its opening and closing, and the PLC controller is electrically connected to the lower receiver and the upper receiver.
[0012] Furthermore, the suction mechanism includes a suction ring, which is evenly installed on the drain holes. An inner cylinder is fixedly connected to the bottom of the inner ring of the suction ring, and an outer cylinder is fixedly connected to the bottom of the outer ring of the suction ring. The inner cylinder and the outer cylinder form a hollow ring cylinder. A drain groove is evenly distributed on the outer ring of the suction ring, and the drain groove communicates with the hollow ring cylinder. A sleeve is movably sleeved on the inner side of the inner cylinder. An air hole is evenly distributed on the moving plate, and the air hole is fixedly connected to the bottom of the sleeve. A piston ring column is also fixedly sleeved on the outer side of the sleeve. The piston ring column is movably sleeved with the hollow ring cylinder. A connecting pipe is connected between the hollow ring cylinders. An outer pipe is connected to the outside of the hollow ring cylinder. When the piston end of the piston ring column moves to the bottom of the interface of the outer pipe, the outer pipe communicates with the upper space of the hollow ring cylinder.
[0013] Furthermore, each end of the outer pipe is connected to a suction pipe, a sewage pump is fixedly installed on the outer side of the left side plate, the input end of the sewage pump is connected to the suction pipe, a collection box is also installed on the outer side of the left side plate, and a drain pipe is connected between the output end of the sewage pump and the collection box.
[0014] The technical effects and advantages of this invention are as follows: When the device is in use, the upper laser generator emits a laser beam, which is received by the upper receiver. After receiving the laser beam, the upper receiver sends an electrical signal to the PLC controller. The PLC controller controls the atomizing plate and the heating element to start. The atomizing plate humidifies the introduced airflow, and the heating element heats the fermentation environment. When the dough ferments and expands to the height of the upper laser generator, the laser beam at that point is blocked, the upper receiver stops sending electrical signals, and the PLC controller controls the atomizing plate and the heating element to turn off, thereby reducing the humidity and temperature of the fermentation environment, reducing yeast activity, and thus preventing the dough from over-fermenting. During the fermentation process, the bottom of the dough is placed on the array of end rods, allowing for sufficient airflow in the space at the bottom of the dough. This ensures that the bottom of the dough also ferments fully, preventing the bottom of the bread from becoming too dense after fermentation, which would affect the texture. When the dough ferments in the device, the moving plate drives the end rod to move upward. At this time, the piston end of the piston ring column also moves to the top of the hollow ring cylinder. The humid airflow diffuses into the upper space through the air hole and the sleeve. When the dough fermentation is complete, the ambient temperature drops, and the humid airflow forms small water droplets on the placement plate. The water droplets aggregate to form a water flow carrying contaminants and impurities into the hollow ring cylinder through the trough. When the moving plate moves downward to reset the end rod, the piston end of the piston ring column also moves to the bottom of the hollow ring cylinder, thereby connecting the outer pipe with the upper space of the hollow ring cylinder. After the sludge pump is started, the water flow carrying contaminants and impurities is absorbed by the outer pipe and discharged into the collection box through the drain pipe. The device uses the above method to absorb and treat the condensate and contaminants and impurities generated after fermentation, thereby improving the cleaning function of the device.

The temperature and humidity precise regulation PLC control device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] First embodiment of the present invention: Reference Figure 1 and Figure 2 The present invention provides a PLC control device for precise temperature and humidity regulation and fermentation, including a fermentation box assembly 1, and a humidification assembly 2 fixedly installed at the bottom of the fermentation box assembly 1; The fermentation chamber assembly 1 includes a front panel 101, a door 102 movably mounted on the upper side of the front panel 101, a front aerator 103 located at the bottom of the door 102, a front filter layer 104 mounted on the rear side of the front aerator 103, and a rear panel 105 on the rear side of the fermentation chamber assembly 1. An exhaust fan 106 is fixedly mounted on the upper end of the rear panel 105, a top plate 107 is fixedly mounted on the upper end of the exhaust fan 106, and an mounting plate 108 is fixedly mounted on the front side of the top plate 107. The inner side of the mounting plate 108 is provided with evenly distributed electric heating tubes 109, and the outer surface of the mounting plate 108 is provided with a PLC controller 110. The left side plate 111 is fixedly installed on the left side of the front box plate 101 and the rear box plate 105, and the right side plate 112 is fixedly installed on the right side of the front box plate 101 and the rear box plate 105. The evenly distributed placement tray 113 is fixedly installed between the front box plate 101 and the rear box plate 105, and the placement tray 113 is provided with evenly distributed drainage holes 114. The humidification component 2 includes a water box 201, which is fixedly installed at the bottom of the fermentation chamber component 1. The front side of the water box 201 is fixedly connected to the bottom side of the front panel 101. A rear filter layer 202 is provided between the rear side of the water box 201 and the rear panel 105. The water box 201 stores pure water and is equipped with an atomizing plate 203. A rear air purifier 204 is also installed on the water box 201. The airflow enters the internal space of the water box 201 from the rear filter layer 202 and is discharged into the bottom space of the placement tray 113 from the rear air purifier 204. The placement tray 113 is higher than the front air purifier 103 and the rear air purifier 204. The PLC controller 110 is electrically connected to the heating element 109 and controls the opening and closing of the heating element 109. The PLC controller 110 is electrically connected to the front air blower 103 and controls the opening and closing of the front air blower 103. The PLC controller 110 is electrically connected to the atomizing plate 203 and the rear air blower 204 and controls the opening and closing of both. The PLC controller 110 is electrically connected to the exhaust fan 106 and controls the opening and closing of the exhaust fan 106. In this embodiment, the dough is placed on the placement tray 113. After the equipment is turned on, the PLC controller 110 controls the heating element 109 and the exhaust fan 106 to start. The heating element 109 heats the internal environment, and the exhaust fan 106 exhausts air. In the early stage of dough fermentation, in order to increase the ambient humidity, the PLC controller 110 controls the front air intake fan 103 and the rear air intake fan 204 to start. The front air intake fan 103 and the rear air intake fan 204 draw air into the interior. The airflow passes through the front filter layer 104 and the rear filter layer 202 for drying and sterilization. After the PLC controller 110 controls the atomizing plate 203 to start, it produces air at the air intake end of the rear air intake fan 204. The generated water vapor mixes with the gas introduced at the rear filter layer 202 to form an airflow carrying fine droplets. This airflow mixes with the dry airflow introduced from the front air pump 103 and diffuses upwards from the leak 114, thereby providing a certain humidity environment for dough fermentation. The PLC controller 110 can adjust the output power of the atomizing plate 203 to adjust the humidity of the mixed airflow. At the same time, the PLC controller 110 can also adjust the output power of the heating tube 109 to adjust the ambient temperature. Therefore, in this embodiment, the device can adjust the temperature and humidity of dough fermentation in the above manner, so that the dough fermentation is more complete.
[0019] The second embodiment of the present invention: Reference Figure 3 and Figure 4 The placement component 3 includes end rods 301, which are evenly distributed in the placement tray 113 and movably connected to it. The bottom of each end rod 301 is fixed to the moving plate 302. Each of the four bottom corners of the moving plate 302 is equipped with an electric cylinder 303. The drive shaft of the electric cylinder 303 is fixedly connected to the four bottom corners of the moving plate 302. The electric cylinders 303 are fixedly installed on the water box 201. A protective cover 304 is also sleeved on the outside of the electric cylinder 303. The drive shaft of the electric cylinder 303 passes through the protective cover 304 and is movably connected to it. A lower laser generator 305 is provided on the inner side of the left plate 111, and an upper laser generator 306 is provided above the lower laser generator 305. A lower receiver 307 is provided on the inner side of the right plate 112, and an upper receiver 308 is provided above the lower receiver 307. The light signal of the lower laser generator 305 is received by the lower receiver 307, and the light signal of the upper laser generator 306 is received by the upper receiver 308. The PLC controller 110 is electrically connected to the electric cylinder 303 and controls its opening and closing. The PLC controller 110 is also electrically connected to the lower receiver 307 and the upper receiver 308. In this embodiment, the dough can be placed on the array end of the end rod 301. The lower laser generator 305 emits laser light, which is received by the lower receiver 307. After receiving the laser light, the lower receiver 307 sends an electrical signal to the PLC controller 110. The PLC controller 110 controls the electric cylinder 303 to start and drive the array of end rods 301 to move upward. When the top of the dough reaches the height of the lower laser generator 305, the laser light at that point is blocked, the lower receiver 307 stops emitting electrical signals, and the PLC controller 110 controls the electric cylinder 303 to turn off. The laser emitted by the upper laser generator 306 is received by the upper receiver 308. After receiving the laser, the upper receiver 308 sends an electrical signal to the PLC controller 110. The PLC controller 110 controls the atomizing plate 203 and the heating tube 109 to start. The atomizing plate 203 humidifies the introduced airflow, and the heating tube 109 heats the fermentation environment. When the dough ferments and expands to the height of the upper laser generator 306, the laser at that point is blocked, the upper receiver 308 stops sending electrical signals, and the PLC controller 110 controls the atomizing plate 203 and the heating tube 109 to turn off, thereby reducing the humidity and temperature of the fermentation environment, reducing yeast activity, and thus preventing the dough from over-fermenting. During the fermentation process, the bottom of the dough is placed on the array end of the end rod 301, and the airflow in the bottom space of the dough is sufficient, so that the bottom of the dough can also be fully fermented, preventing the bottom of the bread from being too dense after fermentation, which would affect the taste.
[0020] The third embodiment of the present invention: Reference Figures 5-8 The suction mechanism 4 includes a suction ring 401, which is evenly installed on the drain holes 114. An inner cylinder 402 is fixedly connected to the bottom of the inner ring of the suction ring 401, and an outer cylinder 403 is fixedly connected to the bottom of the outer ring of the suction ring 401. The inner cylinder 402 and the outer cylinder 403 form a hollow ring cylinder. Evenly distributed drain grooves 404 are provided on the outer ring of the suction ring 401, communicating with the hollow ring cylinder. A sleeve 405 is movably sleeved on the inner side of the inner cylinder 402. The moving plate 302 has evenly distributed air holes 406. The air holes 406 are fixedly connected to the bottom of the sleeve 405. The outer side of the sleeve 405 is also fixedly sleeved with a piston ring column 407. The piston ring column 407 is movably sleeved with the cavity ring cylinder. The cavity ring cylinders are interconnected by a connecting pipe 408. The cavity ring cylinder is connected to an outer pipe 409. When the piston end of the piston ring column 407 moves to the bottom of the interface of the outer pipe 409, the outer pipe 409 is connected to the upper space of the cavity ring cylinder. The outer pipe 409 is connected to the end of the pipe with a suction pipe 410. A sewage pump 411 is fixedly installed on the outside of the left side plate 111. The input end of the sewage pump 411 is connected to the suction pipe 410. A collection box 412 is also installed on the outside of the left side plate 111. A drain pipe 413 is connected between the output end of the sewage pump 411 and the collection box 412. In this embodiment, when the dough ferments in the device, the moving plate 302 drives the end rod 301 to move upward. At this time, the piston end of the piston ring column 407 also moves to the top of the cavity ring cylinder. The humid airflow diffuses upward through the air hole 406 and the sleeve 405. When the dough fermentation is completed, the ambient temperature decreases, and the humid airflow forms small water droplets on the placement plate 113 when it cools down. After the water droplets aggregate, they form a water flow and carry pollutants and impurities into the cavity ring cylinder from the trough 404. When the moving plate 302 moves downward to reset the end rod 301, the piston end of the piston ring column 407 also moves to the bottom of the cavity ring cylinder, thereby connecting the outer tube 409 with the upper space of the cavity ring cylinder. After the suction pump 411 is started, the water flow carrying pollutants and impurities is absorbed by the outer tube 409 and discharged into the collection box 412 through the drain pipe 413. The device uses the above method to absorb and treat the condensate water flow and the pollutants and impurities carried after fermentation, thereby improving the cleaning function of the device.
[0021] The working principle of this invention is as follows: When using the device, the dough is placed on the placement tray 113. After the device is turned on, the PLC controller 110 controls the heating element 109 and the exhaust fan 106 to start. The heating element 109 heats the internal environment, and the exhaust fan 106 exhausts air outward. In the early stage of dough fermentation, in order to increase the ambient humidity, the PLC controller 110 controls the front air intake fan 103 and the rear air intake fan 204 to start. The front air intake fan 103 and the rear air intake fan 204 draw air inward. The airflow passes through the front filter layer 104 and the rear filter layer 202 for drying and sterilization. After the PLC controller 110 controls the atomizing plate 203 to start, the airflow from the rear air intake fan 204... Water vapor is generated at the air intake end. This water vapor mixes with the gas introduced at the rear filter layer 202 to form an airflow carrying fine droplets. This airflow mixes with the dry airflow introduced from the front air intake 103 and diffuses upward from the leak 114, thereby providing a certain humidity environment for dough fermentation. The PLC controller 110 can adjust the output power of the atomizing plate 203 to adjust the humidity of the mixed airflow. At the same time, the PLC controller 110 can also adjust the output power of the heating tube 109 to adjust the ambient temperature. Therefore, in this embodiment, the device can adjust the temperature and humidity of dough fermentation in the above manner, so that the dough fermentation is more complete. During the fermentation process, the bottom of the dough is placed on the array end of the end rod 301, and the airflow in the bottom space of the dough is sufficient, so that the bottom of the dough can also be fully fermented, preventing the bottom of the bread from being too dense after fermentation, which would affect the taste. When the dough ferments in the device, the moving plate 302 drives the end rod 301 to move upward. At this time, the piston end of the piston ring column 407 also moves to the top of the cavity ring cylinder. The humid airflow diffuses upward through the air hole 406 and the sleeve 405. When the dough fermentation is complete, the ambient temperature drops, and the humid airflow forms small water droplets on the placement plate 113 when it cools down. The water droplets aggregate to form a water flow and carry pollutants and impurities into the cavity ring cylinder from the trough 404. When the moving plate 302 moves downward to reset the end rod 301, the piston end of the piston ring column 407 also moves to the bottom of the cavity ring cylinder, thereby connecting the outer pipe 409 with the upper space of the cavity ring cylinder. After the suction pump 411 is started, the water flow carrying pollutants and impurities is absorbed by the outer pipe 409 and discharged into the collection box 412 through the drain pipe 413. The device uses the above method to absorb and treat the condensate water and pollutants and impurities generated after fermentation, thereby improving the cleaning function of the device.
