Description

Technical Field

[0001] The present invention relates to the technical field of baking equipment, in particular to a continuous steam device. Background Art

[0002] In the prior art, there are two types of steam generators for ovens. One is a superheated evaporator, also called a built-in steam generator. The superheated evaporator has a built-in evaporating disk in a dry-burning state, and then uses a solenoid valve to control the external water source to flow into the built-in evaporating disk. The water in the evaporating disk is evaporated into steam through high temperature and then ejected from the exhaust hole. The ejected steam gelatinizes the dough in the oven to form a soft shell, and the dough extends and expands inside to achieve the shape of the bread. The other is a boiling water evaporator, also called an external steam generator. There is a heating disk filled with water at the bottom of the inner cavity of the steamer oven. The water in the water tank is added to the heating disk through the water injection hole, and then the evaporating disk is heated at high temperature to generate steam to heat the food. The heating principle of the boiling water evaporator is similar to that of a steamer.

[0003] The superheated evaporator has the characteristic of high steaming intensity. When in use, the superheated evaporator is heated first and then filled with water. After filling with water, a large amount of steam can be quickly generated in a short time to meet the high-intensity steam required by the oven before baking. However, after generating a large amount of steam, the superheated evaporator cools down and cannot continue to maintain the dry-burning overheating state. It takes heating time to reach the dry-burning state again. During this heating time, the superheated evaporator cannot continue to provide continuous steam to the oven, which will cause the moisture of the ingredients to be lost during the baking process of the oven. Especially when baking bread, it is difficult to bake the soft and chewy European or Asian bread that most people in Asia like to eat. Therefore, the existing superheated evaporator has the problem of short steaming time and moisture loss of ingredients during baking. Summary of the Invention

[0034] In order to further understand the content, features and effects of the present application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0035] See also Figure 1 , Figure 1 This is a three-dimensional diagram of a continuous steam device. The continuous steam device provided in this application includes a steam generating device 1, a superheated steam generator 2 and a steam pipe 3. The steam generating device 1 and the superheated steam generator 2 are both used to generate steam. The superheated steam generator 2 serves as the main steam generator and is used to provide a large amount of steam in a short period of time. The steam generating device 1 is used to continuously provide uninterrupted low-intensity steam. The steam pipe 3 connects the steam generating device 1 and the superheated steam generator 2 respectively, and transports the steam generated by the steam generating device 1 and the superheated steam generator 2.

[0036] See also Figure 2 、 Figure 3 and Figure 4 , Figure 2 This is the exploded view of the steam generating device. Figure 3 This is the exploded view of the superheated steam generator. Figure 4 This is a three-dimensional diagram of a steam generating device. The steam generating device 1 includes a first housing 11, a first heating assembly 12, and a first water injection pipe 13. During operation, the first water injection pipe 13 is connected to the water tank and is used to inject water into the first heating assembly 12. The first heating assembly 12 heats the water injected by the first water injection pipe 13, turning the water into steam. The first housing 11 serves as a reaction vessel and supports the steam.

[0037] A first evaporation chamber 111 is formed within the first shell 11. A first drain port 112 is also provided at the bottom of the first shell 11, communicating with the first evaporation chamber 111. The first heating assembly 12 includes a first heating element 121 and a water tank 122. The first heating element 121 is mounted within the first evaporation chamber 111, and the water tank 122 is connected above the first heating element 121. A first water injection pipe 13 is provided on the first shell 11, with one end extending outside the first shell 11 and the other end extending into the first evaporation chamber 111 and located above the water tank 122. The superheated steam generator 2 is disposed adjacent to the steam generating device 1, and the steam pipe 3 is connected to the first evaporation chamber 111 and the superheated steam generator 2, respectively.

[0038] In specific application, the first water injection pipe 13 of the steam generating device 1 and the superheated steam generator 2 are connected to the water tank respectively, the steam pipe 3 is connected to the baking equipment, and the continuous steam device is connected to the power supply, the steam generating device 1 and the superheated steam generator 2 start to preheat, and after the first evaporation chamber 111 and the superheated steam generator 2 reach the preset temperature, water is started to be injected into the superheated steam generator 2, and a large amount of steam is quickly generated in the superheated steam generator 2, and the steam is transported to the baking equipment through the steam pipe 3. The superheated steam generator 2 completes the high-intensity steaming action required by the pre-baking furnace. In the subsequent baking process, the first water injection pipe 13 continuously injects water into the first evaporation chamber 111 of the steam generating device 1. For water to generate steam, at this time, the first water injection pipe 13 injects water at a small flow rate and continuously. The water injected into the steam generating device 1 by the first water injection pipe 13 reaches the water tank 122 in the first evaporation chamber 111. The water tank 122 is heated by the first heating element 121 and continues to maintain a high temperature state. When the water reaches the water tank 122, it quickly begins to vaporize, and the unevaporated water quickly flows out of the first evaporation chamber 111 from the first drain port 112. The first heating component 12 continues to maintain a dry burning state, so that after the first water injection pipe 13 is injected with water, steam can be continuously generated for baking. The steam generated by the steam generating device 1 is transported to the baking equipment through the steam pipe 3, and the steam generating device 1 continuously provides the steam required for the subsequent stages of baking.

[0039] In this way, through the coordination and compensation of the steam generating device 1 and the superheated steam generator 2, the problems of short steaming time and moisture loss of ingredients during baking existing in a single steam generator are solved. The two steam generators cooperate with each other, and can provide the high-intensity steam required by the oven before baking through the superheated steam generator 2, and can also meet the needs of continuously providing low-intensity steam after baking through the steam generating device 1, thereby ensuring the taste of the baked products.

[0040] Please review Figure 2 and Figure 4 Furthermore, one end of the water tank 122 is located at the pipe mouth of the first water injection pipe 13, and the other end is located at the first drain outlet 112.

[0041] In this way, it is further ensured that the water that flows into the water tank 122 and does not evaporate immediately flows out of the steam generating device 1 quickly through the first drain port 112, so that the first heating component 12 can always maintain a dry-burning overheating state during operation.

[0042] Furthermore, the water tank 122 has a tank bottom wall 1221, two tank side walls 1222 and an end wall 1223. The tank bottom wall 1221 is located above the first heating element 121 and is connected to the first heating element 121. One end of the tank is located at the pipe mouth of the first water injection pipe 13, and the other end is located at the first drain outlet 112. The two tank side walls 1222 are respectively located on both sides of the tank bottom wall 1221. The two tank side walls 1222 are arranged opposite each other, and the tank side walls 1222 and the end wall 1223 are both located on the side of the tank bottom wall 1221 away from the first heating element 121. The end wall 1223 is located at the end of the tank bottom wall 1221 close to the first water injection pipe 13. In this way, a water outlet 1224 is formed at the end of the water tank 122 away from the first water injection pipe 13, so that water that has not evaporated in time can flow out from the water outlet 1224.

[0043] During specific use, the water tank 122 is placed horizontally, or the end of the water tank 122 without the end wall 1223, that is, the end with the water outlet 1224, can be slightly tilted downward. After the water injected by the first water injection pipe 13 flows into the water tank 122, the unevaporated water can quickly flow into the water outlet 1224 of the water tank 122 from the bottom wall 1221 of the tank and flow out of the steam generating device 1 from the first drain port 112, thereby keeping the first heating component 12 in an overheated state.

[0044] Please review Figure 3 Furthermore, the superheated steam generator 2 includes a second shell 21, a second heating component 22 and a second water injection pipe 23. A second evaporation chamber 211 is formed inside the second shell 21. A second drain port 212 is also provided at the bottom of the second shell 21. The second drain port 212 is communicated with the second evaporation chamber 211; the second heating component 22 is arranged in the second evaporation chamber 211; the second water injection pipe 23 includes a second water injection pipe body 231. The second water injection pipe body 231 has a plurality of water injection holes 232. The plurality of water injection holes 232 are dispersed on the second water injection pipe body 231. The second water injection pipe body 231 is arranged in the second evaporation chamber 211 and covers the second heating component 22. One of the pipe openings of the second water injection pipe body 231 extends out of the second shell 21.

[0045] In specific application, the second water injection pipe 23 is connected to the water tank, and the second water injection pipe 23 evenly injects water into the second evaporation chamber 211 through the water injection hole 232 to ensure that the water is evenly spread on the second heating component 22. After the second water injection pipe 23 injects water into the second evaporation chamber 211, the second heating component 22 quickly vaporizes the injected water and transports it to the baking equipment through the steam pipe 3.

[0046] Furthermore, the second heating assembly 22 includes a second heating element 221 and an energy storage element 222; the energy storage element 222 includes an iron pipe 2221 and multiple threaded steel rods 2222, the iron pipe 2221 is arranged in the second evaporation chamber 211, the second heating element 221 is installed in the iron pipe 2222, the threaded steel rods 2222 are superimposed on each other in the second evaporation chamber 211, and they are located below the second water injection pipe 23 and connected to the iron pipe 2221, and the second water injection pipe 23 is arranged on the energy storage element 222.

[0047] In this way, before the second water injection pipe 23 injects water into the superheated steam generator 2, the second heating component 22 can be heated and stored in advance, and the heat generated by the second heating element 221 is stored in the energy storage element 222, that is, the heat generated by the second heating element 221 is transferred to the multiple threaded steel rods 2222 through the iron pipe 2221. After the second water injection pipe 23 is injected with water, it contacts the threaded steel rods 2222, so that the superheated steam generator 2 can quickly generate a large amount of steam in a short time.

[0048] See also Figure 5 , Figure 5 This is a structural diagram of the superheated steam generator after the second shell is hidden. Furthermore, the superheated steam generator 2 also has a baffle 24, which is fixed in the second evaporation chamber 211 and located between the steam pipe 3 and the second water injection pipe 23.

[0049] In specific applications, the superheated steam generator 2 serves as the main steam generator to provide steam for the baking equipment. The temperature in the second evaporation chamber 211 will be very high before steam is generated. After water is injected into the second evaporation chamber 211, it is very likely that small water droplets will be transported to the baking equipment through the steam pipe 3, thereby affecting the taste of the baked products. After the baffle 24 is set, small water droplets can be effectively prevented from entering the steam pipe 3.

[0050] Please review Figure 1 Furthermore, the first shell 11 is located above the second shell 21 and the two are connected to each other.

[0051] In this way, the first shell 11 is arranged above the second shell 21, and the remaining heat of the superheated steam generator 2 can be transferred upward to the steam generating device 1, which ensures that the steam generating device 1 can be heated quickly and the heat of the steam generating device 1 is maintained sufficient, while saving the cost of heating the first heating component 12.

[0052] See also Figure 6 and review Figure 5 , Figure 6This is a schematic diagram of the structure of the temperature sensor fixing member. Furthermore, the superheated steam generator 2 also has a temperature sensor fixing member 25, which includes a hollow tube body 251 and a bottom wall 252. The bottom wall 252 is located at one end of the hollow tube body 251 and is connected to it. The hollow tube body 251 is arranged on the second shell 21. One end of the hollow tube body 251 connected to the bottom wall 252 extends into the second evaporation chamber 211, and the other end is located outside the second shell 21.

[0053] In this way, the continuous heating device can be installed with a temperature sensor probe, which is installed in the hollow tube body 251 and abutted against the bottom wall 252. The temperature sensor probe can be installed in the superheated steam generator 2 to facilitate temperature monitoring.

[0054] See also Figure 8 , Figure 8 It is a structural schematic diagram of a continuous steam device provided with a temperature limiter fixing part, further comprising a temperature limiter fixing part 26, which is located between the first shell 11 and the second shell 21 and is connected to the first shell 11 and the second shell 21 respectively.

[0055] In this way, a temperature sensor probe and a temperature limiter can be installed to provide dual overload protection for the continuous heating device. During specific use, the temperature limiter is installed in the temperature limiter fixing part 26, and the temperature limiter installed in the temperature limiter fixing part is electrically connected to the first heating component 12 and the second heating component 22 respectively. The temperature limiter needs to be set to a predetermined temperature. The temperature limiter senses the surface temperature of the first shell 11 and the second shell 21. When the surface temperature of the first shell 11 or the second shell 21 exceeds the preset temperature of the temperature limiter, the temperature limiter controls the first heating component 12 or the second heating component 22 to stop heating, thereby preventing the steam generating device 1 or the superheated steam generator 2 from being overloaded and damaged.

[0056] See also Figure 7 , Figure 7 Schematic diagram of the structure of the steam pipe. Further, the steam pipe 3 has a first tube body 31, a second tube body 32 and a third tube body 33 connected to each other. The first tube body 31 is connected to the first evaporation chamber 111, and the second tube body 32 is connected to the second evaporation chamber 211.

[0057] When in use, the first tube body 31 is connected to the first evaporation chamber 111, the second tube body 32 is connected to the second evaporation chamber 211, and the third tube body 33 is connected to the baking equipment, so that the steam generating device 1 and the superheated steam generator 2 of the continuous steam device share a steam pipe 3 to transport steam to the baking equipment.

[0058] In summary, the coordination and compensation between the steam generating device and the superheated steam generator solves the problems of short steaming time and moisture loss of ingredients during baking in a single steam generator. The two steam generating devices cooperate with each other, and can provide the high-intensity steam required by the oven before baking through the superheated steam generator, and can also continue to provide low-intensity steam after baking through the steam generating device, thereby ensuring the taste of the baked products.
