[0002] Mooncakes are one of the most famous traditional snacks in my country and a traditional food for the Mid-Autumn Festival. Among them, Cantonese, Beijing, Suzhou, Chaozhou and Yunnan mooncakes are loved by people all over my country. Mooncakes are round and shared by the whole family, symbolizing reunion and harmony. They are a must-eat on the Mid-Autumn Festival. Today, there are many varieties of mooncakes with different flavors. In the production process of mooncakes, they need to be baked in a baking oven after being pressed and formed, and the heat in the baking oven is used to bake the mooncakes.

[0003] At present, there are still the following problems in the process of using a baking box to bake moon cakes: first, due to the temperature difference between different positions inside the baking box, the moon cakes at different positions will be heated inconsistently and unevenly. Some moon cakes are heated too high, while others are heated insufficiently, resulting in the taste, color, and baking degree of the moon cakes baked in the same box being inconsistent, affecting the quality of the moon cakes and the eating experience of consumers; second, when the moon cakes are baked and collected, the box door often needs to be opened continuously, resulting in the loss and waste of a large amount of heat in the baking box while the moon cakes are taken out. The next baking requires a lot of time and energy to be re-preheated and baked, which reduces the efficiency of moon cake baking and the utilization rate of heat, and increases the cost of moon cake baking. Therefore, it is objectively necessary to develop an efficient and energy-saving moon cake baking device that heats the moon cakes evenly, has a good baking effect, and can improve the utilization rate of heat. Utility Model Content

[0004] The utility model aims to provide a high-efficiency and energy-saving moon cake baking device which can heat the moon cakes evenly, achieve good baking effect and improve heat utilization.

[0006] Furthermore, an air outlet pipe of the baking chamber located at the top is connected to an air-to-air heat exchanger, and a hot air outlet of the air-to-air heat exchanger is connected to a cold air inlet of the gas heater.

[0007] Furthermore, a plurality of strip-shaped protrusions are arranged side by side and at intervals on the support plate, and the length direction of the strip-shaped protrusions is parallel to the conveying direction of the intermittent conveyor.

[0008] Furthermore, a plurality of baffles are arranged at intervals on the top of each baking chamber along the conveying direction of the intermittent conveyor, and an air flow channel is left between the lower end of the baffle and the support plate.

[0011] Furthermore, a scraper is obliquely provided on the outer wall of the box below the discharging end of the intermittent conveyor, the end of the scraper is in contact with the surface of the support plate, and a slag receiving groove is provided below the scraper.

[0012] When the utility model is in operation, the gas heater and the intermittent conveyor are started, and the gas is introduced into the box after being heated, and each baking chamber in the box is preheated first to increase the temperature of the baking chamber.

[0016] The present invention is further described below in conjunction with the accompanying drawings, but the present invention is not limited in any way. Any changes or improvements made based on the present invention belong to the protection scope of the present invention.

[0017] like Figures 1-2 As shown, the utility model includes a gas heater 1 and a box 2. The gas heater 1 is a prior art and is used to heat gas to generate hot air. The hot air is used to pass into the box 2 to heat and bake the moon cakes. The internal space of the box 2 is divided into a plurality of baking chambers 4 with the same structure from top to bottom by a partition 3. An intermittent conveyor 5 is provided in each baking chamber 4. The intermittent conveyor 5 is an existing conveying equipment and can intermittently convey the moon cakes. The feeding end and the discharging end of the intermittent conveyor 5 extend out of the opposite side walls of the box 2 respectively. A plurality of support plates 6 are arranged on the intermittent conveyor 5 at intervals along its conveying direction. An air delivery pipe is respectively arranged on the side wall of the baking chamber 4 above the feeding end and the discharging end of each intermittent conveyor 5. The two air delivery pipes are respectively an air inlet pipe 7 and an air outlet pipe 8. The air inlet pipe 7 of the baking chamber 4 at the bottom is connected to the hot air outlet of the gas heater 1, and the air inlet pipe 7 of the upper baking chamber 4 is connected to the air outlet pipe 8 of the adjacent baking chamber 4 below it.

[0018] When the utility model is in operation, the gas heater 1 and the intermittent conveyor 5 are started, and the gas is introduced into the box body 1 after being heated, and each baking chamber 4 in the box body 1 is preheated first to increase the temperature of the baking chamber 4. When the intermittent conveyor 5 is in a stopped state, the moon cakes to be baked are placed on the support plate 6 whose feeding end is exposed to the outside of the box body 2. Subsequently, the intermittent conveyor 5 is operated to deliver this part of the moon cakes into the corresponding baking chamber 4, and the intermittent conveyor 5 stops conveying, and new moon cakes are placed on the support plate 6 exposed to the outside of the box body 1 again, and so on, and the moon cakes are gradually placed on the support plate 6 of the intermittent conveyor 5 until the moon cakes in the baking chamber 4 are completely dried. Until moon cakes are placed on all the supporting plates 6, continue to introduce hot air with the required temperature. The hot air is first introduced into the baking chamber 4 from the air inlet pipe 7, then flows along the conveying direction of the intermittent conveyor 5, is discharged from the air outlet pipe 8 of the baking chamber 4 and introduced into the previous baking chamber 4, and so on. The hot air is introduced into each baking chamber 4 in turn to bake the moon cakes. When the moon cakes are baked, start the intermittent conveyor 5 again, and send the baked moon cakes out of the baking chamber 4 from the discharge end of the intermittent conveyor 5 in turn and take them away. At the same time, new moon cakes are put into the feeding end of the intermittent conveyor 5 as needed, and the baking of the moon cakes can continue.

[0019] During the use of the device, the hot air will pass through each baking chamber 4 in turn, and the whole device is in a flowing state. The hot air at each position is in a state of continuous renewal, avoiding the retention of hot air, so that the temperature difference between different positions inside each baking chamber 4 is small, thereby ensuring that the moon cakes at various positions are heated in a consistent state, and can all be evenly heated, with small differences in baking effects, thereby improving the consistency of taste, color, and baking degree of moon cakes baked in the same box, ensuring the quality of moon cakes and consumers' eating experience; secondly, when placing and collecting moon cakes, it is only necessary to start the intermittent conveyor 5, and only a small amount of hot air will escape from the gap between the intermittent conveyor 5 and the side wall of the box body 1. Compared with the current method of opening the box door for a long time when placing and taking out moon cakes, the amount of hot air escaping is small, and the heat loss and waste is less, which reduces the time and energy required to bake the next batch of moon cakes, thereby improving the baking efficiency and heat utilization of the moon cakes, and reducing the cost of baking moon cakes.

[0020] The air outlet pipe 8 of the baking chamber 4 at the top is connected with an air-to-air heat exchanger 9, which is an existing heat exchange device and can adopt a shell-and-tube heat exchange structure or other heat exchange structures. The hot air outlet of the air-to-air heat exchanger 9 is connected with the cold air inlet of the gas heater 1. The hot air discharged from the box 2 is sent to the air-to-air heat exchanger 9, and the waste heat in the hot air is used to preheat the gas. After the gas temperature is increased, it is introduced into the subsequent gas heater 1, which can reduce the waste of heat and the energy consumed by gas heating.

[0021] A plurality of strip-shaped protrusions 10 are arranged side by side and at intervals on the support plate 6, and the length direction of the strip-shaped protrusions 10 is parallel to the conveying direction of the intermittent conveyor 5. If the surface of the support plate 6 is relatively flat, when the moon cake is placed, the bottom of the moon cake will be tightly attached to the surface of the support plate 6, and the air flow cannot pass between the two, which will reduce the baking quality of the bottom of the moon cake. After the strip-shaped protrusions 10 are arranged, a circulation space for air flow is generated between the bottom of the moon cake and the support plate 6, and hot air can flow through this space, and then the bottom of the moon cake can be baked, increasing the contact area between the moon cake and the hot air, improving the uniformity of the moon cake baking, and then improving the baking efficiency and quality of the moon cake.

[0022] A plurality of baffles 11 are arranged at intervals on the top of each baking chamber 4 along the conveying direction of the intermittent conveyor 5, and an air flow channel 12 is left between the lower end of the baffle 11 and the support plate 6. The arrangement of the baffle 11 can prevent hot air from flowing directly through the top of the baking chamber 4, causing the problem of low heat utilization, and on the other hand, the hot air is blocked and guided, so that the hot air sinks and flows through the air flow channel 12 between the baffle 11 and the support plate 6, and the moon cakes are located in the air flow channel 12, thereby improving the heat utilization and the baking efficiency of the moon cakes.

[0023] The end of the air inlet pipe 7 is extended into the baking chamber 4 and connected to an aerator 13. The aerator 13 is a prior art and is used to evenly distribute the hot air in the baking chamber 4 to improve the baking consistency of each part of the moon cake.

[0024] The outer sides of the feed end and the discharge end of the intermittent conveyor 5 are both covered with covers 14, and the cover 14 is connected to the box body 2 by a mechanism that is easy to open and close. The mechanism that is easy to open and close is a prior art and is used for connecting the cover 14 and the box body 2. Through this mechanism, the cover 14 can be conveniently and quickly fixed to the box body 2, and the cover 14 can also be conveniently removed from the box body 2. In actual use, structures such as snaps can be selected as needed. In the present invention, the intermittent conveyor 5 is installed on the box 2, and both ends thereof extend out of the box 2. In order to ensure smooth moon cake transportation, a certain gap is left between the intermittent conveyor 5 and the side wall of the box 2, so that when the device is running, a small amount of hot air in the box 2 will escape from the gap, causing heat waste. In order to solve this problem, a cover 14 is provided. When the moon cake is baked, the cover 14 is set on both ends of the intermittent conveyor 5 and sealed and fixed on the side wall of the box 2. In this way, the hot air escaping from the gap will enter the cover 14, but because the space in the cover 14 is small, only a small amount of hot air can fill its internal space, and after the internal space of the cover 14 is full, the hot air will no longer escape from the gap, and the heat waste can be greatly reduced in this way. When the moon cake is baked, the cover 14 can be removed from the box 2 for easy collection of the moon cake.

[0025] A scraper 15 is obliquely provided on the outer wall of the box body 2 below the discharging end of the intermittent conveyor 5 , and the end of the scraper 15 contacts the surface of the support plate 6 . A slag receiving trough 16 is provided below the scraper 15 and the discharging end of the intermittent conveyor 5 . When the utility model is in operation, the moon cakes are placed on the support plate 6 for baking. During the baking process, some grease may seep out of the moon cakes on the one hand, and some debris may fall off on the other hand. These grease and debris will adhere to the support plate 6. If they are not cleaned in time, after the moon cakes are taken away, as the intermittent conveyor 5 runs, the support plate 6 will be in a state of facing down, and the grease and debris are located on the front of the support plate 6. At this time, the grease and debris will fall off, which is not convenient for cleaning and will pollute the baking chamber 4. The part that does not fall off will also affect the baking quality of the next batch of moon cakes. Therefore, in order to solve the above-mentioned problem, a scraper 15 is provided. When in use, when the support plate 6 faces down, the scraper 15 contacts the front of the support plate 6, and the grease and debris on the support plate 6 are scraped off outside the baking chamber 4 and fall into the slag receiving groove 16. In this way, the grease and debris can be prevented from falling into the baking chamber 4 to cause pollution, and the baking quality of the next batch of moon cakes can be guaranteed.
