Description

Technical Field

[0001] This utility model belongs to the field of pastry ovens, specifically relating to a hot air rotary oven for producing pastries. Background Technology

[0002] Pastries are made primarily from flour or rice flour, sugar, oil, eggs, and dairy products, along with various auxiliary ingredients, fillings, and seasonings. They are initially shaped and then processed through methods such as steaming, baking, frying, and stir-frying. During pastry processing, baking is often necessary to cook the pastries and improve their texture. A rotary oven, also known as a hot air rotary oven, is a device that uses various energy sources to heat the combustion chamber. Hot air is then delivered into the furnace through a heat exchanger and a fan to bake the items inside.

[0003] In existing hot air ovens, heating is typically done from the side and the baking rack is fixed. Since the baking rack inside the oven cannot rotate, hot air cannot be evenly distributed, which can easily cause the surface of thicker pastries to burn or the inside to remain uncooked when baking them.

[0004] Therefore, a hot air rotary oven for producing pastries is proposed. By installing a motor at the top of the oven box, the rotating shaft drives the baking rack to rotate, so that the pastries can be heated evenly. By having multiple round holes through the side wall of the baking rack, the hot air can fully contact the pastries, thus solving the problem of uneven heating during baking, which causes the surface of the pastries to burn or the inside to remain uncooked.

A connecting block 103 is fixedly connected to the lower end of the rotating rod 102, and a baking rack 104 is fixedly connected to the lower end of the connecting block 103. Multiple round holes 105 are opened through the left and right sides of the baking rack 104. A temperature sensor 106 is fixedly connected to the bottom of the inner wall of the baking rack 104. A motor 101 is set at the upper end of the oven box 1. Driven by the motor 101, the rotating shaft drives the baking rack 104 to rotate, so that the pastry can be heated evenly. The multiple round holes 105 opened through the side wall of the baking rack 104 can make the hot air fully contact the pastry. The temperature sensor 106 is set at the bottom of the baking rack 104, and the temperature of the heating tube 306 can be adjusted in real time, which solves the problem that the surface of the pastry is burnt or the inside is not cooked due to uneven heating during baking.

[0023] Please see Figure 2 In this embodiment, the front of the connecting block 103 is inverted U-shaped, and multiple round holes 105 are evenly distributed on the left and right sides of the baking rack 104. A support column 4 is fixedly connected to the lower edge of the oven box 1, and a support plate 5 is fixedly connected to the lower end of the support column 4. A lighting lamp 11 is fixedly connected to the top of the baking chamber 2. By fixing the lighting lamp 11 to the top of the baking chamber 2, the baking status of the pastry can be observed in real time through the transparent glass 9.

[0024] Please see Figure 3 and Figure 4 In this embodiment, the storage component includes a slide rail 201, a slider 202, a storage box 203, a fixing post 204, a limiting plate 205, and a limiting ring 206. The slide rail 201 is fixedly connected to the left and right sides of the inner wall of the baking rack 104. The slider 202 is slidably arranged on the inner wall of the slide rail 201. The storage box 203 is fixedly connected to the inner side of the slider 202. The fixing post 204 is fixedly connected to the front end of the baking rack 104. The limiting plate 205 is rotatably arranged on the outer wall of the fixing post 204. The limiting ring 206 is fixedly connected to the outer wall of the fixing post 204. By slidably arranging the storage box 203 on the inner wall of the baking rack 104, pastries can be easily taken out. By setting the limiting plate 205 at the front end of the baking rack 104, the storage box 203 can be limited to prevent it from sliding out of the slide rail 201 when rotating.

[0025] Please see Figure 5 In this embodiment, the baking assembly includes a fan 301, an L-shaped pipe 302, branch pipes 303, an air outlet pipe 304, a first groove 305, and a heating pipe 306. The fan 301 is fixedly connected to the bottom of the baking chamber 2. The L-shaped pipes 302 are fixedly connected to the left and right ends of the fan 301. Multiple branch pipes 303 are fixedly connected to the outer wall of the L-shaped pipes 302. Multiple air outlet pipes 304 are fixedly connected to the outer wall of the branch pipes 303. The first groove 305 is opened on the left and right sides of the inner wall of the baking chamber 2. The heating pipe 306 is fixedly connected to the front end of the inner wall of the first groove 305. By setting the air outlet pipe 304 on the outside of the baking rack 104, hot air is circulated in the baking chamber 2, thereby helping to distribute heat evenly and improve baking efficiency.

[0026] Please see Figure 6 In this embodiment, the oven chamber 1 is equipped with a control panel 6, a display screen 7, and control buttons 8 at the front end. The protective door 3 is equipped with a transparent glass 9 at the front end, and a handle 10 is fixedly connected to the front edge of the protective door 3. The motor 101, heating tube 306, temperature sensor 106, fan 301, and lighting 11 are electrically connected to the control panel 6. By providing the control panel 6, the heating tube 306 can be turned off in time when the temperature inside the baking chamber 2 is too high.

[0027] When using the product, first place the pastry into the storage box 203, then slide the storage box 203 onto the baking rack 104, and rotate the limiting plate 205 to limit the storage box 203 to prevent it from sliding out of the slide rail 201 during rotation. Then close the protective door 3 and press the control button 8 to start the heating tube 306, motor 101 and fan 301. Driven by the motor 101, the rotating shaft drives the baking rack 104 to rotate, so that the pastry can be heated evenly. Hot air comes into full contact with the pastry through the round holes 105 on the side wall of the baking rack 104. Through the real-time feedback of the temperature sensor 106, the temperature of the heating tube 306 can be adjusted in time, which solves the problem of the pastry being burnt on the surface or not cooked inside due to uneven heating during baking.

[0028] After the pastries are baked, the fan 301 is started via the control panel 6. The fan 301 delivers cold air to each branch pipe 303 and exhausts it through the air outlet pipe 304, allowing the pastries to cool down slowly and steadily, thus avoiding the problem of burns caused by excessively high pastry temperatures.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
