Abstract
Description
Technical Field
[0001] This invention relates to the field of oiling device technology, specifically to an oiling device for the surface of pastries used in food baking. Background Technology
[0002] Baked goods are convenient foods made from flour, yeast, salt, sugar, and water as basic ingredients, with the addition of appropriate amounts of oil, dairy products, eggs, and additives, through a series of complex baking processes. During the baking process, to improve the texture, color, and prevent cracking of pastries, edible oil is usually applied to the surface.
[0003] However, most existing oiling devices are scattered tools, requiring workers to constantly dip brushes in oil and apply it, which is inconvenient for workers to apply oil to pasta. This method is not only inefficient, but also makes it difficult to ensure the uniformity of oil application, increasing the workload of workers and reducing their efficiency. The oiling process also causes a lot of oil to drip outside the pasta, such as dripping onto the workbench, making cleaning very troublesome and wasting oil. Although there are many automatic oiling or spraying devices in the existing technology, they still have obvious defects: for example, existing automatic oiling devices still cannot effectively prevent oil from dripping when the brush head is not in contact with the pasta; while existing spraying devices can quickly and efficiently spray oil onto the surface of pasta, they also cause a lot of oil waste. Therefore, it is necessary to design an oiling device for pasta surfaces in food baking to improve the defects of existing equipment. Summary of the Invention

[0020] This device also includes a controller, the position of which is set by the operator according to the actual situation during operation. The controller is used to control the electrical components used in this solution, including but not limited to sensors, motors, telescopic rods, solenoid valves, displays, computer input devices, switches, communication devices, lights, speakers, and microphones. The controller is an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is used in conjunction with a motherboard, memory modules, storage media, and power supply, which is AC power or a lithium battery. When a display screen is provided, a graphics card is also included. For the operating principle of the controller, please refer to "Principles of Automatic Control," "Microcontroller Principles and Application Simulation Cases," and "Sensor Principles and Applications" published by Tsinghua University Press. Other books in this field can also be consulted. Other automation control and electrical components not mentioned are knowledge well known to those skilled in the art and will not be described in detail here.
[0021] In use, the dough pieces to be coated are evenly placed in a tray. The tray and dough pieces are then placed on the conveyor 4 via a stacking device. The conveyor 4 moves the tray to a position below the moving device 5 and then stops. The oiling gap is pre-set in the controller, which is the distance between two dough pieces in the direction perpendicular to the conveyor 4. The moving device 5 controls the oiling device 7 to move back and forth and left and right, thus thoroughly coating the surface of the dough pieces with oil. During the oiling process, a pressure sensor is installed at the brush head 78, which is electrically connected to the control device to monitor the contact between the brush head 78 and the dough pieces in real time. When only the upper surface needs to be coated with oil, the arc arm... The brush head 78 at the ends of the two curved arms 75 moves inward towards the fixed brush head 78 in the middle position. Driven by the moving device 5, the upper surface of the surface point is fully coated with oil. When it is necessary to coat the upper and side parts of the surface point with oil, the curved arm 75 moves outward from the curved end 74, and the brush head 78 at the ends of the two curved arms 75 moves to the side of the surface point. By cooperating with the position change and reciprocating movement of the moving device 5, the upper surface and side parts of the surface point are fully coated with oil. By changing the brush head 78 of different lengths, the distance between the two side brush heads 78 can be changed. By changing the brush head 78 of different shapes, such as direction or fan shape, the size of the coating area can be changed. After the brush head 78 comes into contact with the surface, the pressure sensor detects the pressure information, and the control device automatically controls the pressure pump to provide positive pressure. The gas pressure in the pressure pipe 721 drives the oil delivery pipe 720 to deliver oil, and the oil flows out through the oil outlet of the brush head 78. When the brush head 78 leaves contact with the surface, the pressure sensor obtains this information, and the control device automatically controls the pressure pump to provide a relatively small negative pressure. The oil in the oil delivery pipe 720 is recovered to a certain extent. The amount of oil recovered is extremely small, and the recovered oil will flow out in the next oiling process to prevent excess oil from dripping from the brush head 78.
