[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1-3 A continuous hot air dryer for fried rice, specifically designed for this purpose, combines the advantages of hot air drying and continuous production to achieve rapid, uniform, and efficient drying of fried rice. Specifically:

[0026] The dryer includes a frame 1, on which a conveying mechanism 2 for conveying fried rice is installed horizontally. This mechanism is a key component for the continuous conveying of fried rice. One side of the conveying mechanism 2 is set as the input side, and the other side is set as the output side. Preferably, the conveying mechanism 2 is a conveying mesh chain, which has the advantages of strong load-bearing capacity, stable operation, and easy cleaning, making it very suitable for conveying fried rice.

[0027] A hot air drying cylinder 3 is installed on the outside of the conveying mechanism 2. It is the main place for hot air drying of fried rice. A feed port for continuous input of fried rice is provided at the top of the hot air drying cylinder 3 on the input side, and a discharge port for continuous discharge of dried fried rice is provided at the bottom of the hot air drying cylinder 3 on the output side.

[0028] To facilitate the removal of moisture generated during the drying of fried rice, a steam exhaust device 8 is installed at the top of the hot air drying cylinder 3 at the discharge port. Preferably, the steam exhaust device 8 is an exhaust fan, and an exhaust hood that works in conjunction with the exhaust fan is also installed inside the hot air drying cylinder 3.

[0029] To better meet the drying requirements of fried rice, several hot air drying components 4 are sequentially installed on the hot air drying cylinder 3 from the inlet side to the outlet side. Preferably, the hot air drying component 4 includes an air inlet duct, which is connected to the top of the hot air drying cylinder 3 through an air inlet pipe. A heating tube 9 and an air filter 10 are installed inside the air inlet duct, and an air intake fan 11 is installed on the air inlet pipe. This facilitates the delivery of heated and filtered air into the hot air drying cylinder 3 through the air inlet duct, air inlet pipe, and air intake fan 11 to dry the fried rice. The heating tube 9 is responsible for heating the air to an appropriate temperature, while the air filter 10 is used to remove impurities and microorganisms from the air, ensuring that the air delivered into the hot air drying cylinder 3 is clean and hygienic. The air intake fan 11 provides the necessary power.

[0030] Preferably, an air knife 12 connected to the air inlet duct is also installed inside the hot air drying cylinder 3. The design of the air knife 12 allows the hot air to be blown more evenly on the fried rice, improving the drying efficiency. At the same time, in order to make full use of the hot air resources and reduce energy consumption, a return air duct connected to the air inlet duct is also installed on the side of the hot air drying cylinder 3. A one-way valve is installed on the return air duct to ensure that the hot air can only flow in one direction and avoid hot air short circuit or backflow.

[0031] To further improve the drying effect, several dispersing devices 5 are installed inside the hot air drying cylinder 3 to work with the conveying mechanism 2 to break up the fried rice. Each dispersing device 5 includes a support shaft installed horizontally inside the hot air drying cylinder 3, a dispersing rod mounted on the support shaft, and a drive motor mounted on the hot air drying cylinder 3 to drive the support shaft to rotate the dispersing rod. The drive motor drives the support shaft to rotate the dispersing rod, breaking up the fried rice. This helps the hot air to circulate between the fried rice grains, further improving the drying effect. At the same time, the dispersing process can also maintain the loose texture of the fried rice and improve the product quality.

[0032] Secondly, the hot air drying component 4 is provided in 3-5 units, and a dispersing device 5 is provided between each two adjacent hot air drying components 4. This arrangement can not only meet the drying requirements of fried rice, but also maintain the taste and quality of fried rice.

[0033] Several inspection and maintenance ports are also provided on the side of the hot air drying cylinder 3. The inspection and maintenance ports are sealed by the sealing door 6, which not only ensures the airtightness of the equipment, but also facilitates the inspection and maintenance operations of the staff.

[0034] A drainage pipe 7 is also connected to the bottom of the hot air drying cylinder 3 to drain the condensate produced during the drying of fried rice.

[0035] The actual usage process of the continuous hot air dryer for fried rice provided in this application:

[0036] I. Preparatory Work

[0037] Before use, it is necessary to check whether all parts of the fried rice continuous hot air dryer are intact, including the frame 1, conveying mechanism 2, hot air drying cylinder 3, hot air blowing assembly 4, and dispersing device 5. At the same time, it is also necessary to check whether the connections of the power supply, heating tube 9, air inlet fan 11, exhaust fan and other equipment are normal to ensure that the equipment can operate normally.

[0038] Before starting the equipment, the hot air drying cylinder 3 needs to be preheated. The air is heated by the heating pipe 9 and the hot air is sent into the hot air drying cylinder 3 by the air inlet fan 11 to make it reach an appropriate temperature. The preheating time depends on the specific situation of the equipment and the drying requirements of fried rice.

[0039] 2. Add fried rice

[0040] Once the equipment is preheated, fried rice can be added. The fried rice is continuously fed into the hot air drying cylinder 3 through the feed inlet. At the same time, the conveying mechanism 2 starts to run, conveying the fried rice to the output side.

[0041] To ensure that the fried rice is heated evenly, it should be distributed as evenly as possible on the conveyor mechanism 2 when adding the fried rice. If too much fried rice is piled up or unevenly distributed, it may result in poor drying effect.

[0042] III. Drying Process

[0043] During the conveying process, the fried rice will pass through several hot air drying components 4. These components send heated and filtered air into the hot air drying cylinder 3 through the air inlet duct, air inlet pipe and air inlet fan 11 to dry the fried rice. The temperature and wind speed of the hot air can be adjusted according to the drying requirements of the fried rice.

[0044] During the drying process, the breaking device 5 breaks up the fried rice. The drive motor drives the support shaft and breaking rod to rotate, breaking up the sticky parts between the fried rice particles, making them easier to heat and dry. At the same time, the breaking up process can also maintain the loose texture of the fried rice.

[0045] During the drying process, it is necessary to continuously monitor the drying status of the fried rice. If the drying effect of the fried rice is not good or the drying speed is too slow, the temperature and speed of the hot air or the working intensity of the dispersing device 5 can be adjusted appropriately.

[0046] IV. Drain the fried rice

[0047] After the fried rice passes through all the hot air drying components 4 and the dispersing device 5, it will be continuously discharged from the outlet on the output side.

[0048] The fried rice that is discharged needs to undergo quality inspection to check whether the degree of drying, taste and appearance of the fried rice meet the requirements. If any problems are found, the parameters of the equipment or the operation mode need to be adjusted in time.

[0049] V. Cleaning and Maintenance

[0050] After using the continuous hot air dryer for fried rice, the equipment needs to be cleaned, including cleaning the residue inside the hot air drying cylinder 3, cleaning the air inlet cylinder and air inlet pipe, etc. At the same time, it is also necessary to check whether there is any damage or wear on the various parts of the equipment, and repair or replace them in time.

[0051] In summary, the continuous hot air dryer for fried rice provided in this application has the advantages of compact structure, high drying efficiency, good product quality, and simple operation. It can meet the needs of rapid, uniform and efficient drying of fried rice and other foods, and is one of the indispensable pieces of equipment for food production enterprises.
