Description

Technical Field

[0001] This utility model relates to the field of kitchen technology, and specifically to a proofing room. Background Technology

[0002] With the increasing demand for automated catering and the rise of central kitchens, automatic proofing rooms used in pastry making have also seen significant development. For example, Chinese utility model patent CN214629527U discloses a proofing room including a proofing chamber for containing items; a circulation mechanism including a circulating fan, an upper air guide plate, and a lower air guide plate. The upper air guide plate has an air inlet, and the circulating fan draws air from the proofing chamber into the chamber through the air inlet. The lower air guide plate has an air outlet, and air is output through the outlets of the upper and lower air guide plates, forming a circulating air duct. This utility model's proofing chamber structure utilizes a circulating air duct to draw air from the top, send it into the circulating air duct through the air inlet, and then return it to the chamber through the outlet of the lower air guide plate. The circulating air duct structure is located within the proofing chamber, allowing for air circulation between the upper and lower parts. This makes the temperature and humidity within the proofing chamber controllable and allows for controlled variations. Furthermore, the hot air does not lose heat as it flows within the chamber, reducing energy consumption.

[0003] However, the above-mentioned solutions and other similar solutions all have the following problems: the volume of the proofing chamber is too small, which makes it impossible to maximize the volume of the proofing chamber. Therefore, the proofing efficiency of pastries is low, which hinders the further improvement of the scale of central kitchens or catering. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] It should be noted that the descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0033] See Figure 1-7 An embodiment of the proofing chamber of this utility model is shown, comprising: a proofing chamber 1, a circulation device 2, a spiral conveyor tower assembly 4, a humid air output device 3, and a heat source gas output device 5. The proofing chamber 1 is enclosed by a top plate and side walls and is used to accommodate pastries.

[0034] A spiral conveyor tower assembly 4, located within the proofing chamber 1, includes a first spiral conveyor tower 41 and a second spiral conveyor tower 42 arranged opposite to each other. The outer edges of each spiral conveyor tower are configured to be open to maximize the intake of humid and hot air, thereby facilitating proofing. It is understood that this invention does not limit the specific number of spiral conveyor tower assemblies 4. Those skilled in the art can configure two or more spiral conveyor tower assemblies 4 according to proofing requirements and the size of the proofing chamber 1; such structural variations still fall within the protection scope of this invention.

[0035] The first spiral conveyor tower 41 has a first conveyor belt 43 at its front bottom end for transferring the material to be proofed into the first spiral conveyor tower 41. The second spiral conveyor tower 42 has a third conveyor belt 45 at its rear bottom end for transferring the material to be proofed to the next process stage. A second conveyor belt 44 is also provided between the first spiral conveyor tower 41 and the second spiral conveyor tower 42. The second conveyor belt 44 is located at the top of the first spiral conveyor tower 41 and the second spiral conveyor tower 42 to connect the tops of the first spiral conveyor tower 41 and the second spiral conveyor tower 42, and to input the pastry from the first spiral conveyor tower 41 to the second spiral conveyor tower 42. A material inlet is provided on the side wall of the proofing chamber 1 corresponding to the input channel, and a material outlet is provided on the side wall of the proofing chamber 1 corresponding to the output channel, thus enabling continuous cyclic proofing of the pastry.

[0036] The heat source gas output device 5 is used to output heat source gas, which is hot steam in this embodiment, but can also be dry hot air. The humid air output device 3 is used to output humid air, and includes several humidifying pipes 31 disposed in the proofing chamber 1. Each humidifying pipe 31 is provided with a humid air output hole 311. The humidifying pipes 31 and the humid air output device 3 can be connected by a PVC plastic pipe 32 passing through the ceiling of the proofing room.

[0037] The circulation device 2 is installed on the side wall and is positioned at the same height as the spiral conveyor tower group 4. It is used to connect the heat source gas output device 5 and the humid air output device 3 respectively, so as to regulate the temperature and humidity of the spiral conveyor tower group 4.

[0038] By installing the circulation device 2 entirely on the side wall, avoiding the top, the height of the proofing chamber 1 is maximized, providing space for more pastries to proof. This allows for the accommodation of a large spiral conveyor tower, which is connected together by various conveyor belts. Pastries are fed into the spiral conveyor tower via a lower conveyor belt and transferred to the next spiral conveyor tower at a higher point, before being output from the bottom of the next spiral conveyor tower. This increases the travel distance of the pastries within the proofing chamber 1, effectively utilizing the space and improving the proofing efficiency of the pastries.

[0039] The circulation device 2 includes a circulating fan 22, a first variable-diameter connecting pipe 23, an air duct 24, a second variable-diameter connecting pipe 25, and a guide plate 26 arranged vertically from top to bottom. The circulating fan 22 is positioned corresponding to the humid air output hole 311 to blow humid air downwards. The diameter of the first variable-diameter connecting pipe 23 gradually increases downwards in the vertical direction, allowing the humid air to diffuse more evenly through the air duct 24. The diameter of the second variable-diameter connecting pipe 25 gradually decreases downwards in the vertical direction, increasing the flow velocity and decreasing the air pressure as the gas flows through the second variable-diameter pipe, allowing it to move rapidly downwards. The guide plate 26 has multiple output holes arranged vertically to release the humid air blown out by the circulating fan 22 into the proofing chamber 1.

[0040] The humidified air outlet 311 is located on one side of the humidifying tube 31, avoiding its vertical lower position. A cover plate 312 is movably connected to the humidified air outlet 311 via a damping assembly. The cover plate 312 is used to adjust the opening area of ​​the humidified air outlet 311. This creates a water storage area inside the humidifying tube 31 below the outlet, preventing water from condensing into the humidified air from dripping directly into the evaporation chamber 1. Furthermore, the cover plate 312 allows for adjustment of the opening area of ​​the humidified air outlet 311, thus facilitating the adjustment of the humidified air output effect.

[0041] In a preferred embodiment, the air duct 24 is a radiator, which is connected to the heat source gas output device 5 through a heating pipe. When the circulating fan 22 blows humid air downwards, the humid air exchanges heat with the radiator.

[0042] The heat source gas output device 5 includes an input pipe and an output pipe, which are respectively connected to the radiator. The heat source gas output by the heat source gas output device 5 exchanges heat with the air in the proofing chamber 1 through the radiator. The heat source gas output device 5 is used to output high-temperature gas, which can be hot steam or dry hot gas. The humid air output device 3 is used to output room-temperature gas with higher humidity. In operation, the operator can turn on the heat source gas output device 5 and the humid air output device 3 separately according to the specific temperature and humidity requirements, thereby controlling the temperature and humidity in the proofing chamber 1. For example, when heating is required, only the heat source gas output device 5 is turned on; when humidification is required, only the humid air output device 3 is turned on; and when both heating and humidification are required, both the heat source gas output device 5 and the humid air output device 3 are turned on simultaneously, so that the gas is blown into the proofing chamber 1 through the gas output port. In this way, temperature and humidity control can be performed more precisely.

[0043] The radiator includes an enclosed frame 241, within which are arranged several coils 243. The two ends of each coil 243 are connected to the input and output pipes of the heat source gas output device 5, respectively. Each coil is equipped with several heat dissipation fins 244. The gaps 242 between the coils or between the coils and the frame 241 form channels for the passage of humidified gas. In this way, when humidified air is output, some of the residual heat on the radiator can be carried away, thereby improving thermal efficiency and preventing heat waste.

[0044] In another preferred embodiment, the air duct 24 includes a hot steam output port (not shown in the figure), and the air duct 24 is connected to the heat source gas output device 5, which is used to output hot steam. When rapid humidification and heating are required during operation, the heat source gas output device 5 and the humid air output device 3 can be opened simultaneously. The hot steam and humid air mix within the air duct 24 and then enter the air guide plate 26 through the second reducing pipe 25 before being evenly output to the proofing chamber 1, thereby proofing the surface. This method is highly efficient in increasing the humidity within the proofing chamber 1. When the temperature reaches or is about to reach the predetermined temperature, only the humid air output device 3 needs to be opened while the heat source gas output device 5 is closed, allowing for more precise control of the humidity within the proofing chamber 1.

[0045] The bottom end of the air guide plate 26 is also provided with an air guide bend 27 that changes the direction of the gas blowing out to the horizontal direction, thereby providing a guiding effect for the gas at the end of the air guide plate 26, blowing it towards the central part of the proofing chamber 1, so as to make the gas fill the entire proofing chamber 1 as much as possible.

[0046] The circulation device 2 is configured in several units and is evenly arranged on the inner walls of the proofing chamber 1, so that gas can be transported from both sides of the proofing chamber 1 to the middle, thereby increasing the range of proofing points inside the proofing chamber 1.

[0047] The humidified air output device 3 includes a water tank 30, a gas inlet 36, and a humidified air outlet 37. The humidified air outlet 37 is connected to the humidification pipe 31. The water tank 30 contains several atomizers 33, and the gas inlet 36 is equipped with a drive fan 35. The drive fan 35 blows air into the water tank 30, and under the action of the atomizers 33, the atomized water and air mix to form a gas-liquid mixture, which then enters the gas outlet port through the humidified air outlet 37. Preferably, the atomizers 33 are ultrasonic vibration atomizers, which can atomize more finely. The water tank 30 also contains a water level controller 34 to provide an alarm when the water level is low.

[0048] Furthermore, the inner wall of the proofing chamber 1 is also provided with several cooling air outlets 6, which are connected to a cooling fan 62 via cooling air ducts 61. The cooling air ducts 61 are configured as independent pipelines to supplement lower-temperature air when the temperature inside the proofing chamber 1 is too high, thereby cooling the proofing chamber 1 and achieving a more precise temperature control effect. At the same time, because the cooling air outlets 6 are located on the side wall of the proofing chamber 1, the space inside the proofing chamber 1 is utilized more effectively, avoiding interference with the spiral conveyor tower assembly 4 from the height direction.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
