A proofing cabinet for bread production

Abstract

This invention provides a proofing box for bread production, belonging to the technical field of bread proofing boxes. It includes a proofing box with evenly distributed tray racks inside, and a water tank installed at the bottom of the box. Symmetrical upper and lower fixing plates are fixedly connected to the inner sidewall of the proofing box, and a screw is rotatably connected between the two fixing plates via bearings. This invention utilizes spray pipes housed within a lifting frame and a first sliding block that slides with the lifting frame. A multi-stage electric telescopic rod drives the first sliding block to reciprocate along a groove. During cleaning, the spray pipes unfold from within the lifting frame and are perpendicular to it, so that the upper and lower sets of spray pipes are distributed opposite each other on both sides of the tray rack to be cleaned. After water is supplied by a pump, it is sprayed out through high-pressure nozzles. Simultaneously, the multi-stage electric telescopic rod drives the spray pipes to sweep back and forth along the length of the tray rack, achieving close-range high-pressure rinsing of areas difficult to reach by fixed spraying, such as the lower surface of the pipe rack, significantly improving the self-cleaning effect.

Description

Technical Field

[0001] This invention relates to the field of bread proofing box technology, and particularly to a proofing box for bread production. Background Technology

[0002] Proofing boxes for bread production are core equipment in the dough fermentation process, providing a constant temperature and humidity environment for the dough through a sealed cavity and temperature and humidity control system. Currently, the main humidification methods for proofing boxes are divided into bottom-mounted water tray electric heating evaporation and fixed spray systems. The former relies on passive diffusion of water vapor, while the latter uses fixed nozzles installed on the side walls or top of the box to atomize pressurized water and spray it into the cavity. To meet food safety and cleanliness requirements, some proofing boxes have begun to utilize their spray structure for self-cleaning, achieving automatic cleaning of the inner walls of the box by introducing cleaning media into the spray pipes.

[0003] However, existing proofing boxes still have significant shortcomings in terms of humidification uniformity and self-cleaning effect. First, the water mist sprayed from fixed nozzles is affected by gravity settling, resulting in a humidity gradient distribution within the cavity, with higher humidity at the top and lower at the bottom. This causes the surface of the bottom layer of dough to crack while the top layer of dough becomes excessively moist. The root cause is that the spray position is fixed and cannot be dynamically adjusted according to the spatial distribution of the dough. Second, proofing boxes typically have multiple layers of tube racks for placing trays. The lower surface of the tube racks and the corners where the tube racks connect to the box walls are prone to accumulating dough residue and condensation. However, the fixed spray structure has no adjustable spray angle or height. The cleaning jet is blocked by the upper tube racks and cannot reach the lower surface and corner areas of the lower tube racks, resulting in these areas not being effectively cleaned for a long time. The root cause is that the spray position is fixed and cannot achieve close-range sweeping and rinsing between the nozzles and the tube racks. Therefore, this application provides a proofing box for bread production to meet these needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a proofing box for bread production to solve the problems of uneven humidification caused by the fixed spray position of the existing proofing box and the existence of cleaning dead corners in the self-cleaning.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A proofing box for bread production includes a proofing box with evenly distributed tray racks inside. A water tank is installed at the bottom of the proofing box. Symmetrically fixed plates are fixedly connected to the inner wall of the proofing box. A screw is rotatably connected between the two fixed plates via bearings. A first servo motor that drives the screw to rotate is fixedly connected to the inner wall of the proofing box. Two second slides arranged vertically are threadedly connected to the outside of the screw. A lifting frame is fixedly connected to the outside of the second slides. A deflectable cleaning component is sleeved inside the lifting frame. The cleaning component is used for spray cleaning of the outside of the tray racks. The cleaning component includes a spray pipe inside the lifting frame and the first slides. A humidifying component is provided outside the lifting frame for humidifying the inside of the proofing box. The humidifying component includes an atomizing base fixedly connected to the outside of the lifting frame. The cleaning component and the lifting frame are connected by a switching component for switching the working state of the cleaning component. The switching component includes a second servo motor fixedly connected to the outside of the first slides and evenly distributed connecting holes on the inner wall of the lifting frame.

[0006] Optionally, guide rods symmetrically distributed on both sides of the screw are fixedly connected between the two fixed plates, and the guide rods are slidably connected to the second slide.

[0007] Optionally, the spray pipe is sleeved inside the lifting frame, the first slide is slidably connected to the spray pipe, and the first slide is rotatably connected to one end of the spray pipe.

[0008] Optionally, the end of the spray pipe near the first slide is connected to the water tank via a connecting pipe, and the spray pipe is equipped with evenly distributed high-pressure nozzles, and the water tank is equipped with a water pump whose output end is connected to the connecting pipe.

[0009] Optionally, when the spray pipe is fully extended from the lifting frame, the high-pressure nozzles on the spray pipe correspond one-to-one with the pipe racks on the tray frame. The first slide block has a slot on its outside, and the lifting frame has a groove that matches the shape of the slot. The slot engages with the groove.

[0010] Optionally, a fixed frame is fixedly connected to one end of the lifting frame, and a multi-stage electric telescopic rod is fixedly connected inside the fixed frame. The telescopic part of the multi-stage electric telescopic rod is fixedly connected to the first slide.

[0011] Optionally, a through opening adapted to the size of the multi-stage electric telescopic rod is provided between the lifting frame and the fixed frame. The distance between the two lifting frames is greater than the height of the tray frame. A guide groove adapted to the shape of the fixed frame and the multi-stage electric telescopic rod is provided on the inner side wall of the proofing box. Both the fixed frame and the multi-stage electric telescopic rod are inserted into the guide groove.

[0012] Optionally, the atomizing base is L-shaped, with the short side of the atomizing base bent toward the location of the tray frame. A connecting cavity is provided between the atomizing base and the lifting frame, and evenly distributed atomizing nozzles are provided on the outside of the atomizing base.

[0013] Optionally, the drive shaft of the second servo motor extends to the inner side of the first slide and is fixedly connected to the end of the spray pipe. The position of the connecting hole corresponds one-to-one with the position of the high-pressure nozzle on the spray pipe, and the connecting hole and the connecting cavity are interconnected.

[0014] Optionally, a sealing ring is fixedly connected to the end of the connecting hole away from the connecting cavity, and a bevel is provided at the top of the high-pressure nozzle.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, a spray pipe housed in the lifting frame and a first sliding block that slides with the lifting frame are installed. The first sliding block is driven by a multi-stage electric telescopic rod to slide back and forth along the slide groove. During cleaning, the spray pipe unfolds from inside the lifting frame and is perpendicular to the lifting frame, so that the upper and lower spray pipes are distributed opposite each other on both sides of the tray frame to be cleaned. After the water pump supplies water, it is sprayed out through the high-pressure nozzle. At the same time, the multi-stage electric telescopic rod drives the spray pipe to sweep back and forth along the length of the tray frame, realizing close-range high-pressure rinsing of areas that are difficult to reach by fixed spraying, such as the lower surface of the pipe frame, which greatly improves the self-cleaning effect.

[0016] By rotating the spray pipe to the end of the first slide and driving it to deflect by the second servo motor, the cleaning component can automatically switch between unfolded and retracted states. When retracted, the spray pipe does not occupy extra space and does not affect the operation of the humidification component, thus avoiding interference from moving parts to the internal space of the box. When cleaning, the motor drives the spray pipe to deflect and unfold, which can quickly enter the working state. The switching process does not require manual intervention, has a high degree of automation, and effectively reduces labor intensity.

[0017] By creating connecting holes on the inner wall of the lifting frame that correspond one-to-one with the positions of the high-pressure nozzles, and installing sealing rings at the ends of the connecting holes, the spray pipe is retracted into the lifting frame during humidification. The top of the high-pressure nozzle connects to the connecting hole and is sealed by the sealing ring, allowing water to flow through the cleaning pipeline into the atomizing base and be sprayed out by the atomizing nozzle. This achieves the reuse of the cleaning component's pipeline by the humidification component. When the cleaning component is deployed, the high-pressure nozzle disengages from the connecting hole, and the humidification pipeline automatically disconnects. Function switching is completed synchronously by the deflection of the spray pipe. The structure is compact, eliminates the need for additional independent valves, and effectively controls manufacturing costs.

[0018] By setting guide grooves to provide lifting and clearance space for the fixed frame and multi-stage electric telescopic rods, and combining guide rods to limit and guide the second slide, the stability and positional accuracy of the lifting frame's lifting movement under screw drive are ensured. At the same time, the distance between the upper and lower lifting frames is greater than the height of the tray frame, so that the unfolded upper and lower spray pipes can be precisely distributed on the upper and lower sides of the tray frame, ensuring that high-pressure water flow acts on the pipe frame structure from both the upper and lower directions simultaneously, further improving the cleaning coverage and rinsing effect.

[0028] like Figures 1 to 10 As shown, an embodiment of the present invention provides a proofing box for bread production, including a proofing box 1. The proofing box 1 has evenly distributed tray racks 3 inside, and a water tank 2 is installed at the bottom of the proofing box 1. Two symmetrically arranged fixing plates 4 are fixedly connected to the inner wall of the proofing box 1. A screw 5 is rotatably connected between the two fixing plates 4 via a bearing. A first servo motor 7 is fixedly connected to the inner wall of the proofing box 1 to drive the screw 5 to rotate. Two vertically arranged second slides 17 are threadedly connected to the outside of the screw 5. A lifting frame 9 is fixedly connected to the outside of the second slides 17. A deflectable cleaning component is sleeved inside the lifting frame 9. The cleaning component is used for spray cleaning of the outside of the tray racks 3. A humidifying component is provided outside the lifting frame 9 for humidifying the inside of the proofing box 1. The cleaning component and the lifting frame 9 are connected via a switching component, which is used to switch the working state of the cleaning component. In normal working state, the cleaning component is completely stored in the lifting frame 9. At this time, the cleaning component is switched with the humidifying component via the switching component. The connection allows the humidification component to be in a working state. If it is necessary to adjust the humidity at different locations in the proofing box 1, the first servo motor 7 can work and drive the screw 5 to rotate through its drive shaft. Then, the screw 5 pushes the second slide 17 to rise and fall in the proofing box 1 through the external thread, changing the position of the humidification component in the proofing box 1 and performing humidification work. This ensures that the humidity at different locations inside the proofing box 1 is balanced, avoiding the situation where the bottom dough surface is dry and cracked while the top dough is too humid. When it is necessary to clean the internal structure of the proofing box 1 regularly, the switching component works and drives the cleaning component to unfold from the inside of the lifting frame 9. It can slide back and forth along the outside of the lifting frame 9, so that the working area of ​​the cleaning component can completely cover the tray rack 3. With the control of the first servo motor 7, it can fully complete the automatic cleaning of the tray rack 3 in the proofing box 1, realizing close-range sweeping and rinsing of the tube racks of each layer of tray rack 3, greatly reducing the workload of the staff and improving the cleaning effect and cleaning efficiency.

[0029] In this embodiment, as Figures 1 to 3As shown, guide rods 8 are symmetrically distributed on both sides of the screw 5 and fixedly connected between the two fixed plates 4. The guide rods 8 are slidably connected to the second slide 17. The guide rods 8 are used to guide and limit the movement of the second slide 17 in the proofing box 1, so as to prevent the screw 5 from rotating synchronously and driving the second slide 17 to rotate, and to ensure the stability of the second slide 17 when driving the lifting frame 9 to move up and down.

[0030] In this embodiment, as Figures 1 to 6 As shown, the cleaning assembly includes a spray pipe 13 inside the lifting frame 9 and a first slide 16. The spray pipe 13 is sleeved inside the lifting frame 9. The first slide 16 is slidably connected to the spray pipe 13, and the first slide 16 is rotatably connected to one end of the spray pipe 13. The end of the spray pipe 13 near the first slide 16 is connected to the water tank 2 through a connecting pipe 14. The spray pipe 13 is provided with evenly distributed high-pressure nozzles 21. The water tank 2 is equipped with a water pump whose output end is connected to the connecting pipe 14. When the spray pipe 13 is fully extended from the lifting frame 9, the positions of the high-pressure nozzles 21 on the spray pipe 13 correspond one-to-one with the pipe rack on the tray frame 3. The first slide block 16 has a slot 25 on its outside. The lifting frame 9 has a slide groove 20 that matches the shape of the slot 25. The slot 25 is engaged in the slide groove 20. One end of the lifting frame 9 is fixedly connected to a fixing frame 10. The fixing frame 10 has a multi-stage electric telescopic rod 11 fixedly connected inside. The telescopic part of the multi-stage electric telescopic rod 11 is fixedly connected to the first slide block 16. A through opening 18 that matches the size of the multi-stage electric telescopic rod 11 is opened between the lifting frame 9 and the fixing frame 10. The inner side wall of the proofing box 1 has a guide groove 6 that matches the shape of the fixing frame 10 and the multi-stage electric telescopic rod 11. The fixing frame 10 and the multi-stage electric telescopic rod 11 are both inserted into the guide groove 6.

[0031] The distance between the two lifting frames 9 is greater than the height of the tray frame 3. The spacing between the lifting frames 9 ensures that after the two sets of cleaning components are deployed, they can be distributed on the upper and lower sides of the tray frame 3 that needs to be cleaned, ensuring that the water spray during cleaning can completely cover the pipe frame structure of the tray frame 3. The opening of the guide groove 6 provides movement space for the fixed frame 10 and the multi-stage electric telescopic rod 11, allowing the fixed frame 10 and the multi-stage electric telescopic rod 11 to smoothly follow the lifting frame 9 in the proofing box 1 for raising and lowering. When the cleaning components are working, the spray pipe 13 is fully deployed from inside the lifting frame 9. The lifting frame 9 and the spray pipe 13 are perpendicular to each other. The two spray pipes 13 distributed vertically are set opposite each other, so that after the spray pipe 13 is deployed, its external high-pressure nozzle 21 is facing the pipe frame on the same set of tray frames 3. After that, the water pump starts, draws water from the water tank 2 and inputs it into the spray pipe 13 through the connecting pipe 14, and finally sprays the water into the tray frame 3. The high-pressure nozzle 21 on the spray pipe 13 sprays water onto the tube rack of the tray frame 3. At the same time, the multi-stage electric telescopic rod 11 also works and pushes the first slide block 16 to slide along the guide groove 25 and slide 20 on the inner side of the lifting frame 9 through its movable part, changing the position of the spray pipe 13 above the tray frame 3. As the multi-stage electric telescopic rod 11 advances, the high-pressure water jets sprayed by the spray pipe 13 and the high-pressure nozzle 21 can completely cover the tube rack area on the tray frame 3, thereby achieving a comprehensive cleaning of the tray frame 3. Afterwards, the spray pipe 13 retracts into the lifting frame 9, the first servo motor 7 works and adjusts the position of the second slide block 17 and the lifting frame 9 in the proofing box 1, so that the cleaning components move to different tray frames 3. Then the above working steps are repeated until the cleaning work of all the tray frames 3 in the proofing box 1 is completed, so that the proofing box for bread production can efficiently and comprehensively complete the automatic cleaning of the internal structure of the proofing box 1.

[0032] In this embodiment, as Figures 2 to 10As shown, the humidification component includes an atomizing base 12 fixedly connected to the outside of the lifting frame 9. The atomizing base 12 is generally L-shaped, with its short side bent towards the location of the tray frame 3. A connecting cavity 23 is provided between the atomizing base 12 and the lifting frame 9, and evenly distributed atomizing nozzles 19 are provided on the outside of the atomizing base 12. When the cleaning component is fully housed in the lifting frame 9, the humidification component is connected to the water pump and connecting pipe 14 through the structure of the cleaning component, and can perform humidification work. At this time, the first servo motor 7 works and drives the second sliding... The lifting and lowering of the base 17 and the lifting frame 9 inside the proofing box 1 can change the position of the entire humidification component in the proofing box 1. After the water flow is input into the atomizing base 12, it can be atomized and sprayed out through the atomizing nozzle 19 on the atomizing base 12 to achieve humidity control inside the proofing box 1. Since the height of the lifting frame 9 is adjustable, the humidity control inside the proofing box 1 is more balanced, which can effectively improve the proofing effect of bread. In addition, the entire humidification component also makes reasonable use of the mechanism adopted by the cleaning component, thus controlling the overall production cost of the proofing box.

[0033] In this embodiment, as Figures 2 to 9 As shown, the conversion assembly includes a second servo motor 15 fixedly connected to the outside of the first slide 16 and evenly distributed connecting holes 22 on the inner wall of the lifting frame 9. The drive shaft of the second servo motor 15 extends to the inside of the first slide 16 and is fixedly connected to the end of the spray pipe 13. The position of the connecting holes 22 corresponds one-to-one with the position of the high-pressure nozzles 21 on the spray pipe 13, and the connecting holes 22 and the connecting cavity 23 are interconnected. A sealing ring 24 is fixedly connected to the end of the connecting hole 22 away from the connecting cavity 23. The top of the high-pressure nozzle 21 has an inclined surface. When the spray pipe 13 is retracted into the inside of the lifting frame 9, the inclined surface on the high-pressure nozzle 21 abuts against the sealing ring 24 at the end of the connecting hole 22, and under the driving action of the second servo motor 15, the high-pressure nozzle 21 is guided to press the sealing ring 24 to achieve a sealed connection. It is necessary to connect the cleaning assembly and the lifting frame. When the relative positions of the two components are changed, the second servo motor 15 can drive the spray pipe 13 and the first slide block 16 to deflect through its drive shaft, thereby changing the relative position between the spray pipe 13 and the lifting frame 9. There are two position states. The first is the working state of the cleaning component, in which the cleaning component is fully extended and the spray pipe 13 and the lifting frame 9 are perpendicular to each other. At this time, the connection between the humidification component and the water pump and the connecting pipe 14 is disconnected, and the cleaning component can work. The second is the working state of the humidification component, in which the cleaning component is completely housed inside the lifting frame 9, the high-pressure nozzle 21 at the top of the spray pipe 13 is connected to the connecting hole 22, and the connection is sealed by the sealing ring 24. At this time, the humidification component is connected to the connecting pipe 14 and the water pump through the cleaning component, so that water can enter the humidification component for atomization and humidification.
