Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to an integrated device for precise temperature control and oil draining for special fried dough skin. Background Technology

[0002] Specialized deep-frying equipment is a food processing device used for deep-frying various bean products, such as fried tofu skin, fried tofu, and fried dried tofu. Currently, equipment for producing specialized deep-fried skin is widely available on the market, but it addresses several key challenges: First, traditional equipment mostly uses mechanical temperature controllers or thermocouples with deep insertion for temperature measurement. The response speed is slow, the temperature measurement point is single, and it cannot truly reflect the instantaneous temperature of the frying area (especially near the oil surface). Moreover, the oil temperature fluctuates greatly, which can easily lead to uneven heating of the product, resulting in undercooked (undercooked) or overcooked (burnt) products, which seriously affects the quality and consistency of the products.

[0003] Secondly, deep-fried products are usually drained using simple methods such as lifting with a filter or letting the oil drip. This method is passive and inefficient, with the oil relying solely on gravity to flow down naturally. The draining time is short and insufficient, resulting in a high oil content in the finished product, which is greasy and does not meet the needs of modern healthy eating. It also increases the oil consumption cost in production.

[0004] To address the aforementioned problems, this invention provides an integrated device for precise temperature control and oil draining in the production of specialized fried dough skins. Summary of the Invention

[0011] As a further technical solution of this utility model, the upper surface of the rotating oil drain basket is also symmetrically provided with two sets of hanging slots, each set of hanging slots having two slots. The size of the hook is adapted to the size of the hanging slot. The external size of the frying basket is adapted to the internal size of the rotating oil drain basket. When the frying basket is placed in the rotating oil drain basket, the hook is locked in the hanging slot.

[0012] As a further technical solution of this utility model, the rotating oil draining assembly also includes rotating rods symmetrically installed in the middle of the two sides of the rotating oil draining basket. The two rotating rods are fixedly connected to the rotating oil draining basket. Fixed rods are symmetrically installed on the inner wall of the oil draining chamber. The two rotating rods pass through the middle of the two fixed rods and are rotatably connected to them. One end of one of the rotating rods extends through the oil draining tank to its outer wall and is connected to a drive motor. The drive motor is fixed to the outer wall of the oil draining tank by a bracket, and the output end of the drive motor is fixed to one end of the rotating rod.

It utilizes a rotating oil-draining component that combines centrifugal oil removal with gravity-assisted flow. This allows for easy placement of the fried food and frying basket into the rotating oil-draining basket for secure fixation. The tilted design of the rotating oil-draining basket ensures that the product continuously flips and shifts during rotation, preventing product accumulation in the central dead corner and ensuring that each side receives sufficient centrifugal oil removal. The effect is far superior to static dripping. Moreover, tilted centrifugal oil removal can significantly reduce the oil content of the finished product, meeting the trend of healthy consumption. At the same time, the spun-out oil can be collected, filtered, and partially reused, reducing oil consumption and waste. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution for a precision temperature control and oil draining integrated device for special fried dough: a precision temperature control and oil draining integrated device for special fried dough includes a frying box 1, a PLC controller 15 is installed in the middle of the front side of the frying box 1, and an electric heating element 17 is provided at the bottom of the frying chamber 11, which adopts stainless steel finned heating tubes or similar high-efficiency electric heating elements and is arranged at the bottom of the frying chamber. Its features are high thermal efficiency, fast heating, and close coordination with the instructions of the control system. The fryer box 1 is equipped with four support legs 18 at the bottom corners. The support legs 18 are equipped with universal self-locking wheels. The upper front side of the fryer box 1 is equipped with a handrail 14 to facilitate pushing the fryer box 1 to move. The other side of the fryer box 1 is equipped with a folding plate 13 to facilitate placing items.

[0020] The frying box 1 has a frying chamber 11 at the top. The upper part of the frying chamber 11 is symmetrically equipped with hanging rods 12. The frying basket 2 is supported by the two hanging rods 12 inside the frying chamber 11. Two sets of hooks 21 are symmetrically installed on both sides of the frying basket 2. Each set of hooks 21 consists of two hooks, and a handle 22 is connected between each pair of hooks 21 to facilitate the taking and putting away of the frying basket 2. The perimeter wall and bottom of the frying basket 2 are made of mesh to facilitate the draining of oil.

[0021] The perimeter and bottom of the frying basket 2 and the rotating oil draining basket 5 are mesh or have a large number of oil draining holes, and the surface of the cover plate 55 is also provided with oil draining holes. like Figure 5 As shown, an oil draining chamber 3 is provided on one side of the frying box 1. An oil drain pipe 16 extending to the bottom of the frying chamber 11 is installed at the lower end of one side of the frying box 1. An oil drain pipe 2 31 is provided at the bottom corner of the oil draining chamber 3. Both the oil drain pipe 2 31 and the oil drain pipe 16 are equipped with control valves to facilitate oil drainage. The bottom of both the oil draining chamber 3 and the frying chamber 11 are inclined to facilitate the flow and discharge of oil.

[0022] like Figure 1As shown, a baffle 4 is installed on the upper side of both the frying chamber 1 and the draining chamber 3. An infrared thermometer 41 is installed on the baffle 4. The probe of the infrared thermometer 41 is facing the frying area in the frying chamber 11, which is used to monitor the oil temperature in real time without contact. The infrared thermometer 41 is based on the principle of thermal radiation of objects. It does not need to contact the medium and directly measures the true temperature of the oil surface, avoiding the lag of traditional temperature measurement methods. The PLC controller 15 compares this instantaneous temperature with the set value and quickly adjusts the power output of the heating element to achieve dynamic balance. like Figure 3-6 As shown, the inside of the oil draining chamber 3 is equipped with a rotatable rotating oil draining assembly. The rotating oil draining assembly includes a rotating oil draining basket 5 installed inside the oil draining chamber 3. A cover plate 55 is hinged to one side of the upper end of the rotating oil draining basket 5. A slot 56 is provided in the middle of one side of the cover plate 55. A buckle 57 is installed on the other side of the upper end of the rotating oil draining basket 5 corresponding to the slot 56. When the cover plate 55 is closed on the upper end of the rotating oil draining basket 5, the buckle 57 is inserted into the slot 56, and then the cover plate 55 is fixed by the locking ring, thereby fixing the frying basket 2 inside the rotating oil draining basket 5 for easy rotation and oil draining.

[0023] like Figure 6 As shown, the upper surface of the rotating oil drain basket 5 is also symmetrically provided with two sets of hanging slots 54. Each set of hanging slots 54 consists of two hooks. The size of the hook 21 is adapted to the size of the hanging slot 54. The external size of the frying basket 2 is adapted to the internal size of the rotating oil drain basket 5. When the frying basket 2 is placed in the rotating oil drain basket 5, the hook 21 is locked in the hanging slot 54 to ensure the stability of the frying basket 2.

[0024] like Figure 3 As shown, the rotating oil draining assembly also includes rotating rods 51 symmetrically installed on the middle of the two sides of the rotating oil draining basket 5. The two rotating rods 51 are fixedly connected to the rotating oil draining basket 5. Fixed rods 52 are symmetrically installed on the inner wall of the oil draining chamber 3. The two rotating rods 51 pass through the middle of the two fixed rods 52 and are rotatably connected to them. One end of one of the rotating rods 51 passes through the oil draining chamber 3 and extends to its outer wall and is connected to a drive motor 53. The drive motor 53 is fixed to the outer wall of the oil draining chamber 3 by a bracket, and the output end of the drive motor 53 is fixed to one end of the rotating rod 51. The rotating rod 51 and the oil draining chamber 3 are sealed and rotatably connected. The drive motor 53 can drive the rotating oil draining basket 5 to rotate, thereby realizing oil draining.

[0025] The working principle of this utility model is as follows: First, the food to be fried is placed into the frying basket 2, and then the frying basket 2 is hung on the hanging rod 12 using the hook 21. The hanging rod 12 is used to support the frying basket 2. At this time, the food in the frying basket 2 is just located in the oil in the frying chamber 11. Then, the electric heating element 17 is controlled by the PLC controller 15 to heat the oil. In addition, based on infrared thermal radiation temperature measurement technology, the infrared thermometer 41 installed on the baffle 4 non-contactly monitors the instantaneous temperature of the frying area (oil surface and oil layer where the frying basket is located) in the frying chamber in real time, and transmits the temperature signal to the PLC controller 15 in real time. The PLC controller 15 compares the measured temperature with the preset target temperature, and dynamically adjusts the power output (on / off or power adjustment) of the stainless steel finned heating tube at the bottom of the frying chamber 11 through closed-loop control logic such as PID algorithm (PID algorithm built into the PLC controller 15). Since the stainless steel finned heating tube has high thermal efficiency and fast heating, it can quickly respond to control commands and form a negative feedback regulation loop to ensure that the oil temperature is stable within the accuracy range of ±1℃, avoiding the lag and temperature fluctuation problems of traditional temperature measurement methods. After the frying basket 2 finishes frying in the frying chamber 11, it is lifted or transferred by the staff to the tilted rotating drain basket 5. It is stably fixed by the cooperation of the hook 21 and the hanging groove 54. After the cover plate 55 is closed, it is locked by the buckle 57. The rotating drain basket 5 is installed at an angle of 10°-30° on the rotating rod 51. Then, the PLC controller 15 starts the drive motor 53 to work, making it rotate at an adjustable low speed of 50-200 rpm, thereby driving the rotating drain basket 5 to rotate at a low speed. Since the basket is tilted, the product will roll and tumble towards the lower part of the basket wall during the rotation, avoiding accumulation in the central dead corner. At the same time, under the action of centrifugal force, the oil inside and outside is efficiently thrown out and flows into the oil collection tank below through the oil drain hole. After the oil is drained, the drive motor 53 stops, and the product can be taken out.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
